Abstract
The present invention is a kind of shell bearing position restorative procedure, is included the following steps：1. centering, clamping on vertical lathe by shell；2. turning expands the hole of bearing position；3. in bearing position insertion sleeve, sleeve is with bearing position using interference fit；4. being punched on the inner wall of sleeve, punching quantity is no less than two, and punching depth will meet：It drills through sleeve and forms blind hole in inner walls；5. being inserted into holding pin in the hole on the inner wall of sleeve, ensureing in the complete immersed hole of holding pin and being inserted into the blind hole of inner walls, to play the role of fixes sleeve；6. finishing sleeve lining to required size.Step 4. in punching quantity be two, and two holes are arranged in parallel along the direction of bearing position axis.Step 4. in inner walls on blind hole depth be not less than 1.5 times of blind hole diameter.Present invention reduces the cost of the shell parts such as maintenance gear case, bearing block, ensure its required size requirement and accuracy class.
Description
Technical field
The present invention relates to shell part repairing and reusing technical field more particularly to a kind of shell bearing position reparation sides
Method.
Background technology
The shell parts such as gear-box, bearing block are due to designing and processing etc., bearing position interference volume often very little, then
Person often has overload, unbalance loading etc. due to the special running environment factor of gear-box (especially wind turbine gearbox), bearing block
Applying working condition；These reasons are easy to make the bearing outer ring race circle of gear-box, bearing block that bearing position abrasion size be caused to transfinite；When
When gearbox shaft bearing outer-ring runs circle, the service life for reducing gear-box or bearing block can be accelerated；Shell part is a machine
One of the important part of tool device, it is with high costs, therefore, economically consider, the shell part of abrasion is generally returned
It repaiies to reuse, when the shell parts such as gear-box or bearing block are reprocessed, it is necessary to repair bearing position, ensure its size public affairs
Difference and geometric tolerance, general restorative procedure often will fill in axle sleeve after the reaming of bearing position, axle sleeve connect insecure with shell
And low precision, it is easy to occur to wear again quickly.
Invention content
Present invention seek to address that the deficiencies in the prior art, and a kind of shell bearing position restorative procedure is provided.
The present invention to achieve the above object, using following technical scheme：A kind of shell bearing position restorative procedure, including it is as follows
Step：
1. centering, clamping on vertical lathe by shell；
2. turning expands the hole of bearing position；
3. in bearing position insertion sleeve, sleeve is with bearing position using interference fit；
4. being punched on the inner wall of sleeve, punching quantity is no less than two, and punching depth will meet：Drill through sleeve and in shell
Internal wall forms blind hole；
5. being inserted into holding pin in the hole on the inner wall of sleeve, ensureing in the complete immersed hole of holding pin and being inserted into inner walls
Blind hole in, to play the role of fixes sleeve；
6. finishing sleeve lining to required size.
Step 4. in punching quantity be two, and two holes are arranged in parallel along the direction of bearing position axis.
Step 4. in inner walls on blind hole depth be not less than 1.5 times of blind hole diameter.
The beneficial effects of the invention are as follows：Present invention reduces the costs of the shell parts such as maintenance gear case, bearing block, protect
Demonstrate,prove its required size requirement and accuracy class.
Description of the drawings
Fig. 1 is middle casing of the present invention, the connection diagram of sleeve and holding pin；
Fig. 2 is the enlarged drawing at A in Fig. 1；
In figure：1- shells；2- sleeves；3- holding pins；
It is described in detail with reference to attached drawing below with reference to the embodiment of the present invention.
Specific implementation mode
With reference to embodiment, the invention will be further described：
As shown in Fig. 1~Fig. 2, a kind of shell bearing position restorative procedure includes the following steps：
1. centering, clamping on vertical lathe by shell 1；
2. turning expands the hole of bearing position；
3. the insertion sleeve 2 in bearing position, sleeve 2 is with bearing position using interference fit；
4. being punched on the inner wall of sleeve 2, punching quantity is no less than two, and punching depth will meet：Drill through sleeve 2 and
1 inner wall of shell forms blind hole；
5. being inserted into holding pin 3 in the hole on the inner wall of sleeve 2, ensureing in 3 complete immersed hole of holding pin and being inserted into shell 1
In the blind hole of inner wall, to play the role of fixes sleeve 2；
6. finishing 2 inner wall of sleeve to required size.
Step 4. in punching quantity be two, and two holes are arranged in parallel along the direction of bearing position axis.
Step 4. in 1 inner wall of shell on blind hole depth be not less than 1.5 times of blind hole diameter.
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as using the various improvement of inventive concept and technical scheme of the present invention progress, or not improved directly apply to other fields
It closes, within protection scope of the present invention.
