Embodiments of the first aspect
Embodiments of a first aspect of the present application provide a gearbox, fig. 1 is an exploded perspective view of the gearbox, gears, gear cover, and fig. 2 is a top view schematic of the gearbox housing the gears.
As shown in fig. 1, the gear box 1 has a gear drive shaft housing 11 and a gear housing 12. The gear drive shaft accommodating portion 11 accommodates the gear drive shaft 2, and the gear drive shaft 2 extends in the first direction D1. The gear housing 12 houses the gear 3, and the gear 3 may be disk-shaped.
As shown in fig. 1, the gear housing portion 12 includes: a bottom portion 121 and a peripheral wall portion 122.
The bottom portion 121 supports the gear post 4, and the gear post 4 is disposed along a second direction D2, the second direction D2 being perpendicular to the first direction D1. As shown in fig. 2, the gear 3 may be fitted around the outer circumference of the gear post 4.
The peripheral wall portion 122 extends from the outer peripheral portion of the bottom portion 121 in the second direction D2, and surrounds the outer peripheral surface of the gear 3.
As shown in fig. 1 and 2, a groove 1222 is formed in an inner peripheral surface 1221 of the peripheral wall 122 facing the outer peripheral surface of the gear 3, and the groove 1222 is recessed toward the bottom portion 121 from a surface of the peripheral wall 122 away from the bottom portion 121. The groove portion 1222 accommodates lubricant.
According to the first aspect of the embodiment of the present application, the groove portion 1222 for accommodating the lubricant is formed on the inner peripheral surface of the peripheral wall portion 122 of the gear case 1, and the groove portion 1222 is recessed from the surface of the peripheral wall portion 122 to the opposite side (i.e., the side of the bottom portion 121), whereby the lubricant can be easily and reliably applied to the meshing portion of the gear drive shaft and the gear through the opening of the groove portion 1222 at the recess of the surface of the peripheral wall portion 122.
In at least one embodiment, the lubricant contained by the groove 1222 may be, for example: grease, engine oil, solid lubricant, and the like.
In at least one embodiment, the gear housing 1 may be manufactured by resin injection molding, wherein the gear driving shaft housing 11 and the gear housing 12 may be integrally molded parts by injection molding. In the case of applying the lubricant using the groove portion 1222, the gear drive shaft 2 is entirely wrapped around the gear drive shaft housing portion 11 of the gear case 1 except for the meshing portion between the gear drive shaft 2 and the gear 3, and thus the concentricity is improved when the gear drive shaft 2 is attached to the gear drive shaft housing portion 11.
In at least one embodiment, as shown in fig. 1, the peripheral wall portion 122 of the gear housing portion 12 is also formed with a communication hole portion 1223. The communication hole 1223 communicates the gear housing portion 12 and the gear drive shaft housing portion 11. The groove portion 1222 and the communication hole portion 1223 at least partially coincide in the axial direction (i.e., in the second direction) as viewed in the direction perpendicular to the axial direction, that is, the extension of the groove portion 1222 in the axial direction is at least partially the same as the extension of the communication hole portion 1223 in the axial direction. For example, the axial position of the lower end surface of the groove 1222 is the same as the axial position of the lower end surface of the communication hole 1223 or is lower than the lower end surface of the communication hole 1223; for example, the axial position of the upper end surface of the groove 1222 is the same as the axial position of the upper end surface of the communication hole 1223 or is located above the upper end surface of the communication hole 1223. Thereby, the lubricant in the groove portion 1222 can be sufficiently applied to the meshing portion of the gear and the gear drive shaft in the axial direction.
In at least one embodiment, the circumferentially extending longer peripheral wall portion 122 between the groove portion 1222 and the communication hole portion 1223 may be located on the downstream side of the communication hole portion 1223 in the rotation direction of the gear 3, whereby the outer periphery of the gear 3 comes into contact with the lubricant in the groove portion 1222 and the portion of the gear 3 that has come into contact with the lubricant subsequently meshes with the gear drive shaft 2 through the communication hole portion 1223, so that most of the lubricant can lubricate the meshing portion between the gear drive shaft 2 and the gear 3.
In at least one embodiment, the communication hole portion 1223 and the groove portion 1222 are at least 1/2 times the circumferential length of the inner circumferential surface of the circumferential wall portion 122 in the circumferential direction minimum distance in the circumferential direction of the circumferential wall portion 122. Since the circumferential distance between the communication hole 1223 and the groove 1222 is short, most of the lubricant contacting the outer periphery of the gear 3 can lubricate the meshing portion in time.
For example, the circumferential distance between one end of the communication hole portion 1223 in the circumferential direction near the groove portion 1222 and one end of the groove portion 1222 in the circumferential direction near the communication hole portion 1223 is 1/2 or less, preferably 1/4 or less, of the circumferential length of the inner circumferential surface of the circumferential wall portion 122; for another example, the communication hole portions 1223 at least partially overlap with the groove portions 1222 in the circumferential direction (not shown in fig. 1 and 2), whereby most of the lubricant in the groove portions 1222 can enter the communication hole portions 1223.
In at least one embodiment, the inner circumferential surface 1221 of the circumferential wall portion 122 has a circumferential groove (not shown) extending from the communication hole portion 1223 to the groove portion 1222 or extending in the circumferential direction from the groove portion 1222 to the communication hole portion 1223. In one specific embodiment, the circumferential groove communicates with both the communication hole portion 1223 and the groove portion 1222, for example, both circumferential ends of the circumferential groove communicate with the communication hole portion 1223 and the groove portion 1222, respectively. Thus, in a case where the through hole 1223 and the groove 1222 do not overlap in the circumferential direction, the lubricant can enter the communication hole 1223 through the circumferential groove.
As shown in fig. 1, the gear box 1 further has: a protruding part 13. The protruding portion 13 protrudes radially outward from the outer peripheral surface of the peripheral wall portion 122 of the gear housing portion 12. The number of the protruding portions 13 may be at least one, and the at least one protruding portion 13 is distributed along the circumferential direction of the circumferential wall portion 122, for example, the number of the protruding portions 13 of fig. 1 is 4 (2 protruding portions 13 are indicated by a reference numeral).
One protruding portion 13 overlaps the groove portion 1222 as viewed in the radial direction of the gear 3. Although the groove 1222 reduces the rigidity of the peripheral wall 122, the groove 1222 can be made to have a greater thickness in the peripheral wall of the protruding portion 13, thereby complementing the rigidity.
As shown in fig. 1, the protruding portion 13 has a recess 131 that is recessed from a surface away from the bottom portion 121 toward the bottom portion 121 in the axial direction, and the recess 131 can receive a foot portion of the gear cover 14 described below.
As shown in fig. 1, the gear box 1 further has: a gear cover 14. The gear cover 14 may have: a disk-shaped cover 141; a first leg 142 projecting radially outward from the outer peripheral edge of the lid 141; a second foot 143 extending from a radially outer end of the first foot 142 towards the bottom 121. The cover portion 141 may be provided on a side (i.e., an upper side) of the gear 3 away from the bottom portion 121. When the second leg 143 is received in the recess 131 of the protruding portion 13, the cover portion 141 may cover the upper side of the gear 3.
As shown in fig. 1, the second foot 143 may have a protrusion 1431 protruding in the circumferential direction. When the second leg 143 is press-fitted into the recess 131, the protrusion 1431 is fixed to the inner peripheral surface of the recess 131, so that the second leg 143 can be fixed in the recess 131, and the gear cover 14 can be firmly fixed to the gear housing 12.
As shown in fig. 1, the gear housing portion 12 further includes a first wall portion 1224 and a second wall portion 1225 that protrude in a direction away from the bottom portion 121 (i.e., upward) from a surface 122A of the peripheral wall portion 122 away from the bottom portion 121. The first wall portion 1224 and the second wall portion 1225 are opposed to each other in the circumferential direction along the circumferential wall portion 122 with a slit 1226 interposed therebetween.
When the second foot 143 is received in the recess 131 of the protruding portion 13, the first foot 142 of the gear cover 14 may be disposed in the gap 1226. A surface of the first foot 142 facing the bottom portion 121 may directly or indirectly abut a surface 122A of the peripheral wall portion 122 remote from the bottom portion 121. For example, a surface (i.e., a lower surface) of the first leg 142 facing the bottom 121 directly abuts against the surface 122A of the peripheral wall 122, or abuts against the surface via an adhesive or an O-ring. The lubricant in the groove portion 1222 can be suppressed from leaking to the outside of the gear case 1 by the first wall portion 1224, the second wall portion 1225, the lower surface of the first foot 142, and the upper surface 122A of the peripheral wall portion 122.
As shown in fig. 1, inner circumferential surfaces 1224A and 1225A of the first wall portion 1224 and the second wall portion 1225 are located radially outward of the inner circumferential surface 1221 of the peripheral wall portion 122 with respect to the peripheral wall portion 122. Since a part of the groove 1222 is located radially outward of the peripheral wall 122 with respect to the inner peripheral surfaces 1224A and 1225A of the first wall 1224 and the second wall 1225, the groove 1222 can be formed to have a large radial dimension, and thus the groove 1222 has a large capacity.
As shown in fig. 1, the groove portion 1222 is located further radially inward of the peripheral wall portion 122 than the recess 131, thereby defining the maximum value of the radial dimension of the groove portion 1222 and preventing the lubricant in the groove portion 1222 from leaking.
According to the embodiment of the first aspect of the present application, the groove portion for accommodating the lubricant is formed in the inner peripheral surface of the peripheral wall portion of the gear case, whereby the lubricant can be easily and reliably applied to the meshing portion of the gear drive shaft and the gear.
Embodiments of the second aspect

Since the structure of the gear box has been described in detail in the embodiment of the first aspect, the contents thereof are incorporated herein, and the description thereof is omitted here.
In embodiments of the second aspect of the present application, the motor assembly may also have a motor (not shown), a geared drive shaft 2 and a gear 3. Wherein the motor drives the gear drive shaft 2 to rotate, the gear drive shaft 2 is meshed with the gear 3, so that the gear 3 is driven to rotate, and the rotation of the gear 3 can be transmitted to the outside of the gear box through the connecting structure. As for the structure of the motor, reference can be made to the related art.
In the embodiments of the second aspect of the present application, the field in which the motor assembly can be used is not limited, and for example, the motor assembly may be used in a sunroof drive system of an automobile, or in other fields.
According to the embodiment of the second aspect of the present application, by forming the groove portion for accommodating the lubricant in the inner peripheral surface of the peripheral wall portion of the gear case, it is possible to easily and reliably apply the lubricant to the meshing portion of the gear drive shaft and the gear, thereby extending the service life of the gear drive shaft and the gear and improving the reliability.
The present application has been described in conjunction with specific embodiments, but it should be understood by those skilled in the art that these descriptions are intended to be illustrative, and not limiting. Various modifications and adaptations of the present application may occur to those skilled in the art based on the spirit and principles of the application and are within the scope of the application.
