Abstract
A tractor differential gear assembly with a lining mainly comprises a shell body, a differential gear left semi shaft gear, a differential gear planetary gear, a differential gear planetary gear shaft and a differential gear right semi shaft gear, wherein an inner hole of the differential gear planetary gear is equipped with the matched component lining, the differential gear planetary gear shaft is equipped in the differential gear planetary gear lining, the differential gear left semi shaft gear and the differential gear right semi shaft gear are equipped on the differential gear shell body, and a differential gear planetary gear shaft pin 6 is equipped on the differential gear shell body and tightened. The utility model maintains the differential gear shell body and the left and right semi shaft gear on the basis of the prior each types differential gear, only reasonably designed lining is added on the inner hole of the differential gear planetary gear to apply in the differential gear assembly, which can effectively increase the using life of the differential gear, with a good social and economic benefit.
Description
(1) technical field:
The utility model belongs to the tractor field, relates to a kind of tractor differential assembly of belt material cover.
(2) background technique:
The tractor differential assembly of China's production at present, its differential pinion gear endoporus directly contacts and relatively rotates with the differential spider pinion shaft diameter of axle, this structure has solved the wearing and tearing between differential spider pinion shaft and the differential pinion gear endoporus and has lubricated, but the processing and the heat treatment of differential spider pinion shaft and differential pinion gear is had very high requirement; Differential spider pinion shaft requires to process oil groove behind the wear-resisting phosphatization surface.Its shortcoming is part processing and heat treatment process complexity, and manufacturing efficiency is low and cost is higher; Moreover, on differential spider pinion shaft, to process oil groove in order to improve the lubricating condition of planetary pinion and planet pin, can enter abrasive dust in the Sump lubrication oil excessively and cause differential pinion gear endoporus and differential mechanism planet wheel shaft to add galling.
(3) summary of the invention:
The purpose of this utility model be to provide a kind of reduce differential pinion gear endoporus and differential mechanism planet wheel shaft between the two frictional force, improve lubricating condition, improve the tractor differential assembly of the belt material cover of bearing capacity.
The utility model can be achieved through the following technical solutions above-mentioned purpose: the tractor differential assembly of belt material cover is mainly by differential casing 1, differential left differential gear 2, differential pinion gear 3, differential spider pinion shaft 5, differential mechanism right axle shaft gear 7 is formed, it is characterized in that: be pressed with the composite bush 4 that matches with it in differential pinion gear 3 endoporus, differential spider pinion shaft 5 is packed in the differential pinion gear bush hole, differential left differential gear 2, differential mechanism right axle shaft gear 7, the differential casing of packing into, differential spider pinion shaft pin 6 are packed into and are locked in the differential casing 1.
The utility model can reach following beneficial effect: keep differential casing, left and right sides differential gear constant in existing various differential assemblies, only need in the differential pinion gear endoporus, to install lining additional by reasonably designing lining profile and size, be used for differential assembly, can overcome the above-mentioned shortcoming of the tractor differential assembly of present China production.Improve the working life of differential assembly, had good society and economic benefit.
(4) description of drawings:
Fig. 1 is the tractor differential assembly structural representation of the utility model belt material cover.
(5) embodiment:
As shown in Figure 1, the tractor differential assembly of belt material cover mainly is made up of differential casing 1, differential left differential gear 2, differential pinion gear 3, differential spider pinion shaft 5, differential mechanism right axle shaft gear 7, be pressed with the composite bush 4 that matches with it in differential pinion gear 3 endoporus, differential spider pinion shaft 5 is packed in the differential pinion gear bush hole, differential left differential gear 2, differential mechanism right axle shaft gear 7, the differential casing of packing into, differential spider pinion shaft pin 6 are packed into and are locked in the differential casing 1.
Differential mechanism is not under the differential working condition: the power that the tractor differential assembly of belt material cover passes over from motor drives differential casing 1 and rotates, the moving differential spider pinion shaft 5 of differential casing 1 rotating band rotates, the planetary pinion of belt material cover rotates with the moving differential mechanism left and right half gear 2,7 of differential spider pinion shaft 5 rotating band together, differential mechanism left and right half gear level is rotated, do not relatively rotate between belt material cover planetary pinion and the planet pin 5, differential mechanism does not play differential action.
Under the differential mechanism differential working state: the power that the tractor differential assembly of belt material cover passes over from motor drives differential casing 1 and rotates, the moving differential spider pinion shaft 5 of differential casing 1 rotating band rotates, the planetary pinion of belt material cover rotates with the moving differential mechanism left and right half gear 2,7 of differential spider pinion shaft 5 rotating band together, and the planetary pinion of belt material cover rotates the differential action that left and right two- semiaxle gear 2,7 different rotating speeds of realization are realized differential assembly relative to differential spider pinion shaft 5.
Claims (1)
1. the tractor differential assembly of belt material cover, mainly by differential casing (1), differential left differential gear (2), differential pinion gear (3), differential spider pinion shaft (5), differential mechanism right axle shaft gear (7) is formed, it is characterized in that: be pressed with the composite bush (4) that matches with it in differential pinion gear (3) endoporus, differential spider pinion shaft (5) is packed in the differential pinion gear bush hole, differential left differential gear (2), differential mechanism right axle shaft gear (7) differential casing (1) of packing into, differential spider pinion shaft pin (6) are packed into and are locked in the differential casing (1).
