Description
Technical field
The utility model relates to tractor differential, especially a kind of 30-40 horsepower wheel type tractor differential gear planetary pinion fixing device.
Background technique
At present, the 30-40 horsepower wheeled tractor that domestic production is sold is all to adopt two planet gear type differential mechanisms substantially, and wherein planetary pinion and differential casing only depend on a planet pin to fix.This conventional planetary pinion fixing device, its drawback is that the stationarity of transmission is poor, when the load-carrying of tractor is loaded when large, under the effect of torque force, differential axle very easily ruptures, and causes the planetary pinion shock differential casing that flies out, cause housing to break, thereby make the working life of differential mechanism short.
In view of above-mentioned reason, existing tractor differential planetary pinion fixing device need to be improved innovation.
Model utility content
The utility model object is to overcome deficiency of the prior art, and a kind of 30-40 horsepower wheel type tractor differential gear planetary pinion fixing device is provided, simple in structure, easy to manufacture, coordinates differential mechanism stable drive, and anti-load-carrying load obviously strengthens; Greatly reduce the ratio of planetary pinion axle fracture, reduce maintenance and maintenance cost, increase the service life; Improve complete machine of tractor performance, saved cost of production; Be convenient to promote, meet multiple market and user's demand.
The utility model is in order to realize above-mentioned object, adopt following technological scheme: a kind of 30-40 horsepower wheel type tractor differential gear planetary pinion fixing device, by planetary pinion minor axis, planet pin coupling block, planetary pinion major axis, planetary pinion major axis fixed hole, planetary pinion minor axis fixed hole forms; Planet pin coupling block middle part arranges planetary pinion major axis fixed hole, in planetary pinion major axis fixed hole, planetary pinion major axis is set; Planetary pinion major axis 3 both sides arrange planetary pinion minor axis fixed hole, in planetary pinion minor axis fixed hole, planetary pinion minor axis are set.
Upper and lower planetary pinion minor axis coaxial line correspondence is arranged on the both sides of planetary pinion major axis 3.
The utility model contains planetary pinion minor axis, planetary pinion major axis and coupling block; Planetary pinion minor axis one end is linked together through coupling block and coupling block, and one end is fixed by fixed hole in addition; When planetary pinion major axis passes coupling block, one end is fixed by fixed hole; Planetary pinion minor axis, planetary pinion major axis are linked together by coupling block.
The beneficial effects of the utility model are: simple and compact for structure, design science is reasonable, easy to use, handling safety.Simple in structure, easy to manufacture, coordinate differential mechanism stable drive, anti-load-carrying load obviously strengthens; Greatly reduce the ratio of planetary pinion axle fracture, reduce maintenance and maintenance cost, increase the service life; Improve complete machine of tractor performance, saved cost of production; Be convenient to promote, meet multiple market and user's demand.
The utility model is easy to assembly, improve the stationarity of transmission, when the load-carrying of tractor, load when large, at utmost reduce the planetary pinion causing because of the fracture of planetary pinion fixing device and clash into the housing that housing causes and break, thereby increase the working life of differential mechanism, reduce maintenance and maintenance cost.This structure investment is low, is convenient to promote on 30-40 horsepower wheeled tractor; Be widely used in farm tractor.Saved cost of production; Meet multiple market and user's demand, reduce the financial cost of peasant household, invest low, easy to utilize.
