Abstract
The utility model relates to an integral differential mechanism which is used on an agricultural transporting vehicle, the structure is that a casing body is integration, the casing body is provided with two asymmetrical square holes on the left and right sides, a shaft of a planet gear is arranged in the casing body between the two holes, and a planet gear and a gear of a half shaft are arranged on the shaft of the planet gear, and a reduction gear is arranged outside the casing body. The utility model has the advantages of simple structure, firm integration, high reliability, high loading capability, safe use, easy installation and maintenance and high productive efficiency and completely satisfies the needs of the agricultural transportation vehicles.
Description
The integral type differential device that the utility model relates to is a kind of three, use on the four-wheel agricultural vehicle, integral type differential device in the particularly conjuncted back axle gearbox.
The differential mechanism that uses on the agricultural vehicle is split type differential mechanism at present, by a left side, right two halves connect by 8～10 bolts, a left side, right two halves housing has oilhole entirely, oilhole is little, oil inlet quantity is few, and planetary pinion and differential gear greasy property in the housing are poor, and the gear engagement situation is difficult to check, assembly precision is low, the two halves housing connects by 8～10 bolts, if when having the of poor quality or back axle bearing load of bolt big, bolt just may be cut off, thereby the gear in the damage gearbox casing, influence gearbox back axle working life, aborning, amount of finish is big, manufacturability is poor, after the assembling, be difficult to guarantee complex structure with conjuncted back axle joint bearing step coaxality, the cost height, manufacturing efficiency is low.
The utility model purpose provides a kind of novel integral type differential device, can effectively solve three, use the safety of differential mechanism on the four-wheel agricultural vehicle and problem efficiently.
This suitable novel purpose is achieved in that to be transformed existing split type differential mechanism, make it become overall structure, opposed two square holes are arranged on the housing, be convenient to assemble planetary pinion and differential gear, check the gear engagement situation, in housing internal diameter pin hole planet pin is housed, planetary pinion and differential gear are arranged on it, housing external diameter taper pin is equipped with reduction gear.
The utility model structural entity is solid, and assembling is simple, good manufacturability, and the reliability height, bearing capacity is big, and is safe in utilization, and cost is low, the manufacturing efficiency height.
Following structure accompanying drawing elaborates to structure of the present utility model.
Fig. 1 is the utility model structural profile plan view.
By shown in Figure 1, the utility model be by housing and planet pin and on planetary pinion, differential gear and outside reduction gear constitute, housing 4 is an integral body, the left and right square hole 9,8 that symmetry is arranged on it, planet pin 3 is housed in the housing between two square holes, planetary pinion 5 and differential gear 2 are arranged on it, the housing 4 outer reduction gear 7 that are equipped with, and having taper pin 6 fixing, planet pin 3 is fixing by round pin axle 1.
The utility model housing can adopt cast inblock, once finish, in producing and using, having overcome split type differential casing is that left and right two halves connect by 8～10 bolts, and amount of finish is big, and manufacturability is poor, halved body combination rear bearing step coaxality is difficult to guarantee, split type differential casing upper oil hole is little, and oil inlet quantity is few, the problem of planetary pinion and differential gear greasy property difference.The integral type differential device is convenient to assemble planetary pinion because of left and right two opposed big square holes on the housing, checks the gear engagement situation, amount of finish is little, and bearing step coaxality easily guarantees, the assembly precision height, the gear lubrication performance is good, uses reliably long service life, housing is rationally distributed, easy to assembly, the charge material amount improves 2～3 times, good reliability, satisfied the needs of agricultural transportation vehicle fully, it applies well received.
