Abstract
The utility model discloses a carburization planetary gear gasket, its appearance are the body of conical canal shape, and this body is through carburization, and the lateral wall section of this body is circular-arc, and the less port edge of this body is inflected inwards and is formed annular groove of borduring the bottom in groove of borduring is equipped with rather than communicating storage tank the storage tank intussuseption is equipped with lubricating grease the inner wall of body is equipped with the lubrication channel of falling "V" shape, and this lubrication channel communicates with each other with the storage tank be equipped with the friction recess on the outer wall of body. Therefore, the technical effects of high strength and reliable structure are achieved, and the planetary gear is more stable and reliable in operation.
Description
Technical Field
The utility model relates to an accessory among the automotive differential, concretely relates to carburization planetary gear gasket.
Background
The differential structurally comprises a differential shell, a planetary gear, two planetary gear gaskets, a cross shaft, a left half shaft gear and a right half shaft gear, wherein the two planetary gears, the left half shaft gear and the right half shaft gear are respectively adjusted on the cross shaft and are in meshed transmission with each other, the back surface of the planetary gear is in a frustum cone shape, the common gasket is in a circular ring shape, and after the two planetary gears, the left half shaft gear and the right half shaft gear are arranged between the planetary gear and the inner wall of the differential shell, large friction force exists between the planetary gear and the gaskets, the planetary gear gaskets rotate along with the planetary gear, the planetary gear gaskets and the inner wall of the differential shell are abraded, the normal working position of the planetary gear is affected after abrasion, meshing engagement between the planetary gear and the left half shaft gear and the right half shaft gear is not tight.
Disclosure of Invention
In order to solve the above problems, an object of the present invention is to provide a carburized planetary gear spacer with high strength and reliable structure, so that the planetary gear is more stable and reliable in operation.
In order to achieve the above purpose, the utility model provides a following technical scheme: a carburization planetary gear gasket is a cone-shaped body, the body is subjected to carburization treatment, the section of the side wall of the body is arc-shaped, the edge of a smaller port of the body is bent inwards to form an annular edge covering groove, the bottom of the edge covering groove is provided with a containing groove communicated with the containing groove, lubricating grease is filled in the containing groove, an inverted V-shaped lubricating channel is arranged on the inner wall of the body and is communicated with the containing groove, and a friction groove is formed in the outer wall of the body.
The friction groove comprises a first strip-shaped friction groove and a second pentagram-shaped friction groove, the first friction groove is arranged at the position of a large port of the body and is circumferentially and uniformly distributed, and the second friction groove is arranged at the interval position of the first friction groove.
The utility model discloses a structure, can laminate on planetary gear's a side end face, it bordures hole end position of groove extensible to planetary gear, can make planetary gear one end location, lubricating grease in the storage tank can be taken out to the lubrication way along with planetary gear's rotation simultaneously, make to have the lubricity between body inner wall and the planetary gear more, reduce the friction, and friction recess and differential mechanism casing increase frictional force on the outer wall, just so make can not rotate along with planetary gear at the work body, and frictional force has been reduced, and intensity is higher after the body carburization, the wearability is better, the life-span that can effectively improve the use, so just, the technological effect that intensity is high and the structure is reliable has been realized, thereby make planetary gear more reliable and more stable in operation.
The invention is further described with reference to the accompanying drawings and the detailed description.
Drawings
FIG. 1 is a perspective view of an embodiment of the present invention;
FIG. 2 is a sectional view of an embodiment of the present invention;
fig. 3 is an enlarged view of a in fig. 2.
Detailed Description
The present invention will be specifically described below by way of examples.
As shown in fig. 1-3, the embodiment discloses a carburized planetary gear spacer, which has a tapered body 1, the body 1 is carburized, the cross section of the sidewall of the body 1 is arc-shaped, the smaller end edge of the body 1 is bent inward to form an annular edge-covering groove 2, the bottom of the edge-covering groove 2 is provided with a containing groove 3 communicated with the containing groove, the containing groove 3 is filled with grease, the inner wall of the body 1 is provided with an inverted "V" -shaped lubrication channel 4, the tip of the lubrication channel 4 is close to the end edge of the body 1, the lubrication channel 4 is communicated with the containing groove 3, and the outer wall of the body 1 is provided with a friction groove 5.
The friction groove 5 comprises a first strip-shaped friction groove 51 and a second pentagram-shaped friction groove 52, the second pentagram-shaped friction groove is provided with a plurality of edges which are vertical and horizontal, friction force can be improved, the first friction groove 51 is arranged at the position of a larger port of the body 1 and is circumferentially and uniformly distributed, and the second friction groove 52 is arranged at the interval position of the first friction groove 51. The arrangement of the first friction groove 51 and the second friction groove 52 mainly increases the contact area as much as possible, and meanwhile, the friction groove 5 can be in concave-convex fit with irregular parts on the inner wall of the differential body 1, so that the friction force between the body 1 and the inner wall of the differential body 1 is further improved, and the reliability of the structure fit structure is improved.
Adopt technical scheme, can laminate on planetary gear's a side end face, it bordures the hole tip position that groove 2 extendible to planetary gear, can make planetary gear one end location, simultaneously the lubricating grease in the storage tank 3 can be taken out to lubrication way 4 along with planetary gear's rotation on, make and have the lubricity more between 1 inner wall of body and the planetary gear, reduce the friction, and friction groove 5 and the differential mechanism casing on the outer wall increase frictional force, just so make and can not rotate along with planetary gear at work body 1, and reduced frictional force, and body 1 carburization back intensity is higher, the wearability is better, can effectively improve the life-span that the gasket used, just so realized intensity height and the reliable technological effect of structure, thereby make planetary gear more reliable and more stable in operation.
