Description
Technical field
The utility model is related to a kind of automobile-used planet row, the planet wheel bearing screens knot of specifically a kind of planet row
Structure.
Background technology
China's relevant policies are to the subsidy of new-energy automobile, encouragement in recent years and support, also promote car enterprise to enter one after another and are somebody's turn to do
Field.And in many professionals, why the pure electric automobile of conventional " keeping up appearances " mixes motor-car by plug-in has been robbed public attention,
Or it is relevant with its current Predicament of Development.
Because infrastructure speedup is relatively slow, charging turns into many consumers temporarily insoluble realistic problem.This
Outside, the technical problem such as battery durable mileage is also urgently to be resolved hurrily.In face of technical bottleneck, the volume production plan of automobile vendor and market
Popularization also seems that extremely with caution not existing effect increases market reaction all the time.
By contrast, plug-in mixes motor-car type and efficiently solves the problems, such as the course continuation mileage of pure electric automobile, and by traditional power
System is combined together with pure power-driven power system, compensate for respective inferior position, and the advantage of both sides is maximized.In this background
Under, many experts think, compared to pure electric automobile, and plug-in hybrid electric vehicle type is more suitable for situation instantly.
Bearing inside the planetary gear of the planet row used in existing bus is cooperation really up to the mark, not spacing up and down.OK
Star-wheel ran at high speed after a period of time, along with the stress of bearing, caused the moving up and down of bearing, and meeting pair is so used for a long time
Bearing and planet wheel spindle cause larger abrasion, influence the precision of planet row, bearing, which is axially moved, can also produce into abnormal sound.
Utility model content
The purpose of this utility model is just to provide a kind of planet wheel bearing retaining structure of planet row, is expert at solving bearing
The problem of play causes planet wheel spindle abrasion big and influences planet row precision on spider gear shaft.
What the utility model was realized in：A kind of planet wheel bearing retaining structure of planet row, the planet row includes
Planet carrier, sun gear and some planetary gears, the planetary gear are arranged in the planet carrier, are worn in each planetary gear and are connected to row
Spider gear shaft, is connected to bearing between planetary gear and planet wheel spindle, in wearing on the shaft hole inner wall for connecing planet wheel spindle for the planetary gear
Upper and lower two necks are provided with, the neck on top is located at the upper edge of the bearing, and the neck of bottom is located at the bearing
Lower edge, one jump ring of clamping in each neck, the jump ring is stuck in the up/down edge of the bearing.
The utility model has added two jump-ring slots in the bearing position of planetary gear, bearing is placed on the axis hole of planetary gear, two
Hold first-class jump ring, you can effectively prevent the axial movement of bearing.
The utility model is the once innovation to planet row, it is therefore prevented that the axial movement of planet wheel bearing, reduces bearing
And the abrasion of planet wheel spindle, it is ensured that planet row normal operation and fit precision, extend the service life of planet carrier.
Utility model is suitable for the planet row of the various vehicles such as bus automobile, car, car.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of planet row.
In figure：1st, planet wheel spindle, 2, jump ring, 3, planetary gear, 4, bearing.
Embodiment
As shown in Figure 1 and Figure 2, planet row includes planet carrier, sun gear and planetary gear 3, sun gear（It is not shown）It is centrally located
In the middle part neutral of planet carrier 5, four planetary gears 3 are set in planet carrier, are in surround situation to sun gear placed in the middle, and
It is meshed with sun gear.
In Fig. 1, worn in each planetary gear 3 and be connected to planet wheel spindle 1, bearing is connected between planetary gear 3 and planet wheel spindle 1
4, upper and lower two necks are provided with the shaft hole inner wall for connect planet wheel spindle in wearing for planetary gear 3, the neck on top is located at bearing 4
Upper edge, the neck of bottom is located at the lower edge of bearing 4, and one jump ring 2 of clamping in each neck, the jump ring 2 on top is stuck in bearing 4
Upper edge, the jump ring 2 of bottom is stuck in the lower edge of bearing 4, is consequently formed the planet wheel bearing retaining structure of planet row.
When hybrid power system works, planetary gear 3 rolling bearing, two jump-ring slots can prevent bearing to be axially moved, and reduce
The abrasion of bearing 4 and planet wheel spindle 1, it is ensured that the normal operation of planet row and precision, extends the service life of planet carrier.
