Abstract
The utility model relates to a planetary wheel, which comprises a planetary wheel body, wherein a groove is arranged on the end surface of the planetary wheel body. Because the groove in radial arrangement is arranged on the end surface of the planetary wheel body, lubricating oil can realize the lubricating effect on slide bearings and the end surface of the planetary wheel body through the groove, the gap between the slide bearings and the end surface of the planetary wheel body is smaller, the axial floating of the planetary wheel in the rotation process can be reduced, the vibration noise in the planetary wheel rotation process can be avoided, and the service life of the planetary wheel can be prolonged. Because the processing precision of the planetary wheel does not need to be improved, the processing cost of the planetary wheel can not be increased.
Description
Technical field
The utility model relates to a kind of mechanical transmission component, specifically, relates to a kind of planet wheel.
Background technique
Planet comes in automatic transmission and the driving mechanism and generally uses, planet row generally comprises planet carrier and a plurality of planet wheels that are arranged on the planet carrier, the excircle place of planet carrier is provided with cavity, planet wheel is positioned at cavity and is connected with planet carrier by bearing pin, be provided with sliding bearing between the end face of planet wheel and the planet carrier, be provided with the gap between the end face of planet wheel and the sliding bearing, lubricant oil is lubricated by the end face of this gap to sliding bearing and planet wheel.
In the course of the work, the rotating speed of planet wheel is very high, the rotating speed of planet wheel is up to 20,000 commentaries on classics/per minutes in automatic transmission case, owing to have the gap between the end face of planet wheel and the sliding bearing, under high-revolving situation, the axial float of planet wheel is bigger, is easy to generate vibration noise, and influences planet wheel and planet row's working life.In order to reduce vibration noise, planet wheel reaches and the machining accuracy of its meshed gears by improving usually, and along with the raising of machining accuracy, its processing technology requires high more, and then has improved processing cost.
The model utility content
Problem to be solved in the utility model is at above problem, provide a kind of axial float in the course of the work little, be difficult for to produce vibration noise, long service life, planet wheel that cost is low.
For addressing the above problem, the technological scheme that the utility model adopted is: a kind of planet wheel, comprise the planet wheel body, and the end face of described planet wheel body is provided with groove.
As a kind of optimized project, described groove is arranged on two end faces of planet wheel body.
As a kind of optimized project, described groove follows the radially setting of star-wheel body.
As a kind of optimized project, the cross section of described groove is an arc.
A kind of concrete optimized project is respectively arranged with several grooves on two end faces of described planet wheel body.
A kind of concrete optimized project, the quantity that is positioned at the groove on one of them end face of planet wheel body equates with the quantity of groove on being positioned at another end face of planet wheel body.
A kind of concrete optimized project, the groove that is positioned on one of them end face of planet wheel body is symmetrical arranged with the groove that is positioned on another end face of planet wheel body.
A kind of concrete optimized project, the groove that is positioned on the planet wheel body end face follows circumferentially evenly distributing of star-wheel body.
A kind of concrete optimized project, each end face of described planet wheel body is provided with 6 grooves.
The utility model is taked above technological scheme, have the following advantages: because the end face of planet wheel body is provided with the groove that radially is provided with, lubricant oil can be lubricated by the end face of groove to sliding bearing and planet wheel body, so can make the gap between the end face of sliding bearing and planet wheel body littler, thereby reduced the axial float of planet wheel in rotation process, thereby avoided the vibration noise in the planet wheel rotation process, prolonged the working life of planet wheel, owing to do not need to improve the machining accuracy of planet wheel, so can not improve the processing cost of planet wheel.
The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 2 is the sectional view of accompanying drawing 1;
Accompanying drawing 3 is the assembly structure schematic representation of planet wheel;
Accompanying drawing 4 is the left view of accompanying drawing 3.
Among the figure:
The 1-planet wheel; 2-planet wheel body; The 3-groove; The 4-bearing pin; The 5-oil duct; The 6-sliding bearing; 7-first planet carrier; 8-second planet carrier.
Embodiment
Embodiment: as shown in Figures 1 and 2, a kind of planet wheel, comprise cylindrical planetary wheel body 2, be respectively arranged with 6 grooves 3 on two end faces of planet wheel body 2, six grooves 3 follow circumferentially evenly distributing of star-wheel body 2, groove 3 follows the radially setting of star-wheel body 2, and the cross section of groove 3 is an arc, and the excircle of planet wheel body 2 is provided with the gear teeth.
The groove 3 that is positioned on planet wheel body 2 one of them end face is symmetrical arranged with the groove 3 that is positioned on planet wheel body 2 another end faces.
Can increase or reduce the quantity of groove 3 as required, the shape of groove 3 cross sections also can be other shapes, as triangle, rectangle etc., groove 3 on two end faces also can adopt other modes in the setting that makes progress in week, and groove 3 also can only be arranged on the end face of planet wheel body 2 as required.
Shown in accompanying drawing 3 and accompanying drawing 4, planet carrier is made up of first planet carrier 7 and second planet carrier 8, first planet carrier 7 and second planet carrier 8 weld together, the excircle place of planet carrier is provided with the cavity that holds planet wheel 1, the excircle of planet carrier is provided with four planet wheels 1, and planet wheel 1 is connected with planet carrier by bearing pin 4, and bearing pin 4 is provided with oil duct 5, be provided with needle bearing between bearing pin 4 and the planet wheel 1, be provided with sliding bearing 6 between the end face of planet wheel 1 and the planet carrier.
In planet wheel 1 working procedure, lubricant oil enters by oil duct 5, through behind the needle bearing, enter in the groove 3 on planet wheel 1 end face, parts of lubricating oil enters in the groove 3 from the cavity that holds planet wheel 1 simultaneously, the lubricant oil that enters in the groove 3 is lubricated the end face and the sliding bearing of planet wheel 1, because planet wheel 1 is provided with groove 3, so the end face and the gap between the sliding bearing of planet wheel 1 are very little, effectively reduced the axial float of planet wheel 1 in rotation process, thereby avoided the vibration noise of planet wheel 1 in rotation process, prolonged the working life of planet wheel 1.
