Description

Rolling bearing device with rotatable bearing pressing plate
Technical Field
The invention belongs to the technical field of bearings, and relates to a rolling bearing device with a rotatable bearing pressing plate.
Background
In the automobile transmission, the bearing is used as a key part of the automobile transmission, the design and manufacturing quality of the bearing influence the performance and the service life of the automobile transmission, and the correct installation and use method and the reasonable peripheral fixing structure of the bearing have important influence on the service life of the bearing and the automobile transmission.
At present, in the application of the bearing in the automobile transmission, the bearing is combined with the peripheral parts and components thereof, and the use of the bearing as a bearing unit is a trend. Therefore, the assembling process of the automobile transmission can be simplified, the assembling efficiency is improved, a more reasonable peripheral structure and a more reasonable fixing mode can be provided for the application of the bearing, the service life of the bearing is prolonged, the service life of the automobile transmission is prolonged, the use and maintenance cost of a user is reduced, and the carbon emission of an automobile in the life cycle is reduced.
In general, as shown in fig. 1, a rotating shaft (input shaft or intermediate shaft) 5 of an automobile transmission is located inside a case 1 and rotates supported by a rolling bearing 3. The bearing inner ring 10 of the rolling bearing 3 is mounted on the end of the rotating shaft 5 in a manner such as interference fit, which suppresses circumferential sliding, and is axially fixed by the snap ring 4 and the step of the rotating shaft 5. For ease of assembly, the outer race 9 of the rolling bearing is mounted in a freely sliding manner, such as a clearance fit, at the recess 2 of the housing 1. Therefore, the relative sliding phenomenon between the outer ring 9 of the rolling bearing and the concave part 2 of the box body can occur during the use process of the transmission. The long-time relative sliding causes the surface of the box concave part 2 to be worn, the clearance between the bearing outer ring 9 and the box concave part 2 is increased, abnormal noise is generated, and the transmission is scrapped.
At present, it is a common practice to solve the problem that the outer ring 9 of the rolling bearing body 3 is provided with a bearing outer ring stepped groove 9a, the bearing pressure plate 6 is installed on the bearing outer ring stepped groove 9a of the rolling bearing through a special structure B, and the bearing pressure plate 6 and the rolling bearing body 3 constitute a bearing unit. In order to facilitate the mounting of the bearing unit on the transmission, it is necessary to ensure that the bearing pressure plate 6 cannot fall off the rolling bearing 3 before assembly, and it is also necessary that the bearing pressure plate 6 can rotate freely on the rolling bearing 3. The bearing pressure plate 6 is provided with a plurality of assembly threaded holes 8, and the bearing unit can be arranged on the box body 1 through the threaded holes 8 and the bolts 7. Since there is a certain gap Δ c between the bearing pressure plate 6 and the housing 1 before installation, the bearing pressure plate 6 is tightened by the bolts 7 after installation to elastically deform the bearing pressure plate 6, and the bearing outer ring 9 is firmly fixed by the elastic force. In the running process of the transmission, the bearing outer ring 9 is not easy to slide relative to the box body concave part 2, so that noise is not easy to generate, and the service life of the bearing and the transmission is prolonged. Therefore, a special structure that allows the bearing retainer 6 to rotate freely on the rolling bearing 3 without falling off the rolling bearing 3 becomes a key for improving the life of the bearing and the transmission.
Patent CN 203067568U describes a rolling bearing unit with a bearing pressure plate. The bearing pressure plate and the bearing are combined by a snap ring with a plurality of convex outer diameter locking parts, and a plurality of grooves corresponding to the convex outer diameter locking parts of the snap ring are formed on the bearing pressure plate. When the combination operation is carried out, the bearing pressing plate presses the outer diameter locking part of the clamping ring to be flattened along the axial direction to the inner side, other parts of the clamping ring do not excessively protrude outwards along the radial direction and do not interfere with the inner diameter surface of the bearing pressing plate, and therefore the outer ring is stably combined with the baffle plate.
Patent CN 104870845 a discloses a method for manufacturing a rolling bearing with a bearing pressure plate. The bearing outer ring is provided with a groove in the circumferential direction, and the bearing pressure plate is provided with a plurality of structures which have special shapes and can deform along the radial direction. When the combination operation is carried out, the material of the deformable part of the bearing pressure plate is extruded and deformed by pressure, and at least part of the material is moved into the groove in the circumferential direction of the bearing outer ring, so that the bearing pressure plate is ensured not to fall off from the bearing.
In the above two patents, the manufacturing of the snap ring with special structure and the stamping die with the bearing press plate with special shape and deformation is complex, and the size is difficult to control. And the material needs to be subjected to plastic deformation by pressure processing, the plastic deformation amount is difficult to control, and the dispersion difference is large. The size precision of the clamping ring and the bearing pressure plate and the technological requirement for implementation of combined operation are high, and the phenomenon that the bearing pressure plate falls off from the bearing outer ring or the bearing pressure plate and the bearing outer ring are clamped easily occurs.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
Fig. 1 to 7 show a housing 1, a housing recess 2, a rolling bearing body 3, a snap ring 4, a rotating shaft 5, a bearing pressure plate 6, a bearing pressure plate stepped groove 6a, a bolt 7, a threaded hole 8, a bearing outer ring 9, a bearing outer ring stepped groove 9a, a bearing outer ring groove 9B, a bearing outer ring stepped surface 9-a, an inner ring 10, a snap ring 11, a retainer 12, a retainer bottom 12a, a rolling element 13, a seal structure 14, a special structure B, and the like.
As shown in fig. 1 to 7, the invention is a rolling bearing device with a rotatable bearing pressing plate, comprising a rolling bearing body 3 and a bearing outer ring step groove 9a arranged on a bearing outer ring 9 of the rolling bearing body 3, wherein the bearing pressing plate 6 is arranged at the bearing outer ring step groove 9a in a matching manner, and the bearing pressing plate 6 is tightly attached to a step surface 9-a at the bearing outer ring step groove 9 a; the rolling bearing body comprises a bearing inner ring 10, a retainer 12, a rolling body 13 and a bearing outer ring 9; the inner hole of the bearing pressing plate 6 is provided with a bearing pressing plate step groove 6a, the axial outer side of the bearing outer ring step groove 9a is provided with a bearing outer ring groove 9b, a clamping ring 11 is arranged in the bearing outer ring groove 9b, and the clamping ring 11 limits the bearing pressing plate 6.
The method for combining the rolling bearing body 3, the bearing pressure plate 6 and the clamping ring 11 comprises the following steps; firstly, a bearing pressure plate 6 is arranged in a bearing outer ring step groove 9a of a bearing outer ring 9 of a rolling bearing body 3, and the bearing pressure plate 6 is attached to a bearing outer ring step surface 9-A at the bearing outer ring step groove 9 a. Then, the snap ring 11 is fitted into the bearing outer ring stepped groove 9a along a gap Δ L1 between the bearing presser stepped groove 6a and the bearing outer ring stepped groove 9 a.
It can be understood that, in order to ensure reliable position limitation of the bearing pressure plate 6, the wire diameter of the clamping ring 11 is larger than the depth Δ H2 of the bearing outer ring groove 9b, and the part of the clamping ring 11 protruding out of the bearing outer ring groove 9b forms position limitation on the clamping ring 11, so as to prevent the bearing pressure plate 6 from falling off the bearing outer ring 9. A gap Delta L3 is formed between the clamping ring 11 and the bearing pressure plate 6, and the bearing pressure plate 6 can freely rotate on the bearing outer ring 9.
The inner ring of the bearing pressure plate 6 and the outer ring of the bearing outer ring stepped groove 9a have a gap Δ L. The bearing outer ring stepped groove 9a has a width Δ H1 and a depth Δ H2. In order to ensure that the bearing pressure plate 6 can be easily arranged on the bearing outer ring step groove 9a, and the bearing pressure plate 6 can flexibly rotate on the bearing outer ring. The clearance delta L between the inner diameter of the bearing pressure plate 6 and the bearing outer ring step groove 9a is more than or equal to 0.15mm, and the clearance delta L is less than or equal to 0.2mm in order to prevent the bearing pressure plate 6 from falling off.
The minimum thickness between the bottom of the raceway of the bearing outer ring 9 and the step groove 9a of the bearing outer ring is delta h, the delta h is more than or equal to 0.25 multiplied by Dw, and the Dw is the diameter of the rolling body 13. In order to ensure the thickness Δ h, the bearing outer ring 9 and the bearing inner ring 10 can be designed to be offset, that is, the distance B1 between the center of the inner and outer ring raceways and the two end faces is not equal to B2, as shown in fig. 6. The width B2 of the side of the bearing outer ring step groove 9a is larger than B1. To prevent the bearing cage 12 from interfering with the seal 14, the cage 12 is a plastic cage and its cage bottom 12a should be on the larger side of B1 and B2.
In order to ensure the manufacturability and the strength of the clamping ring 11 and prevent the cover plate from falling off, the diameter of the clamping ring 11 is W, the inner diameter is Dr, and W =0.5~1.5 mm. Its inner diameter Dr =0.95 × Ds, Ds is the diameter of the bearing outer ring groove 9 b. The fastening ring 11 needs to be fitted through the gap Δ L1 between the bearing retainer plate stepped groove 6a and the bearing outer ring stepped groove 9 a. Since the material of the clamping ring 11 can be compressed, this gap Δ L1 ≈ W. The width and depth of the bearing pressure plate step groove 6a determine the strength of the bearing pressure plate, so the wire diameter W of the clamping ring 11 related to the part is less than or equal to 1.5 mm. The clamp ring 11 is fitted in the bearing outer ring groove 9b to ensure that the clamp ring 11 does not fall off the bearing outer ring groove 9b and is easily fitted, and has a sufficient protrusion amount Δ L2 to prevent the bearing presser 6 from falling off. The width delta H1 of the bearing outer ring groove 9b is approximately equal to W, the width delta H2 is approximately equal to 0.5 multiplied by W, and the diameter Ds is approximately equal to 1/0.95 multiplied by Dr. In order to ensure that burrs are not easily generated from the bearing outer ring groove 9b to the bearing end face in the machining process, the distance between the bearing outer ring groove 9b and the end face is delta H3 which is approximately equal to W +1.0 mm.
The depth of the bearing-outer-ring groove 9b is half the diameter of the clamp ring 11, and the width of the bearing-outer-ring groove 9b is substantially equal to the diameter of the clamp ring 11.
The distance between the bearing pressure plate step groove 6a and the bearing outer ring step groove 9a is equal to the diameter of the clamping ring 11.
In the specific production practice, the clamping ring 11 can be made of rubber, and according to different use temperature requirements of the bearing, rubber made of materials such as NBR, ACM, HNBR, FKM and the like can be adopted, and a rubber ring with a certain wire diameter and inner diameter can be made as required.
The clamping ring 11 can also be made of spring steel, and an annular spring with a certain wire diameter and inner diameter can be made according to requirements.
It can be understood that the bearing pressure plate 6 is further provided with a threaded hole 8 to ensure that the bearing pressure plate 6 is installed on the box body 1 through the threaded hole 8 and the bolt 7 when the product of the invention is used, and because a gap Δ c exists between the bearing pressure plate 6 and the box body 1, the bearing pressure plate 6 can generate elastic deformation in the locking process of the bolt 7, and the elastic force generated by the deformation presses the bearing outer ring through the step surface 9-A of the bearing outer ring 9, so that the bearing outer ring 9 and the box body 1 are not easy to slide relatively in the working process. In order to ensure the contact strength between the bearing pressure plate 6 and the step surface 9-A, the complete contact length H of the bearing pressure plate 6 and the step surface 9-A is more than 0.10 Dw. And the thickness t at the bearing pressure plate step groove 6a needs to be as large as possible, and t is approximately equal to delta H3. In order to ensure that the bearing pressure plate 6 is installed at the bearing outer ring 9 to rotate flexibly, a fillet R1= Min0.3mm is arranged at the bearing pressure plate step groove 6 a.
The rolling bearing 3 is not limited to the ball bearing shown in the figure, and may be a roller bearing.
Further, the cage 12 of the rolling bearing 3 is not limited to the plastic cage of the illustrated embodiment, and may be a low carbon steel stamped cage.
Further, the rolling elements 13 of the rolling bearing 3 are not limited to the bearing steel material, but may be a ceramic material.
Further, the sealing device 14 of the rolling bearing 3 is not limited to the rubber seal ring of the illustrated embodiment, and may be a metal dust cap.
The invention has the technical effects that: according to the invention, through the optimized design of the matching parts of the bearing pressure plate, the bearing outer ring and the clamping ring, the problem that the bearing pressure plate is not easy to fall off on the bearing outer ring and cannot be locked is realized. The device has the advantages of simple structure, convenient assembly, lower requirements on the dimensional accuracy of the bearing pressure plate, the bearing outer ring and the clamping ring, reduction of the manufacturing cost and high reliability. The problems of high requirement on the dimensional accuracy of each part, difficulty in assembly, easiness in falling and blocking in the prior patent technology are solved.
The above description has been given only for the details of the presently novel preferred embodiment. Various modifications and additions may be made to the described embodiments or may be substituted in a similar manner by those skilled in the art to which the present invention pertains, and the technical scope of the present invention should be determined by the claims, and the meaning equivalent to the contents of the claims and all modifications within the scope thereof should be included.
