Abstract
A cantilever planet wheel reducing mechanism for a vehicle drive axle comprises a blocking cushion, a roller pin, a bolt, a flat washer, a planet wheel shaft, a cylindrical pin, a gasket, a planet wheel, and a planet wheel frame. The planet wheel shaft is sleeved on the planet wheel frame in an interference fit mode, the gasket is mounted between the planet wheel and the planet wheel frame, the blocking cushion is mounted on the planet wheel shaft, the bolt is mounted between the blocking cushion and the planet wheel shaft through the flat washer, the cylindrical pin is arranged between the blocking cushion and the planet wheel shaft, and the roller pin is arranged between the planet wheel shaft and the planet wheel. By means of the cantilever planet wheel reducing mechanism, operation reliability of a cantilever planet wheel of the cantilever planet wheel reducing mechanism is effectively improved, impact of the roller pin to the blocking cushion is avoided, and the strength of the planet wheel shaft is improved. The cantilever planet wheel reducing mechanism is compact in structure, good in reliability and convenient to use and repair.
Description
Technical field
The utility model belongs to the vehicle drive axle field, relates to a kind of vehicle drive axle reducing gear, relates in particular to a kind of vehicle drive axle cantilever planet gear reducing mechanism.
Background technique
At present, in the vehicle drive axle parts of domestic main flow, ransaxle planetary gear speed reducing mechanism used is mainly the planet wheel cantilever.Process jump-ring slot on planet wheel shaft, by the mode of jump ring and gear pad, prevent the play of needle roller between planet wheel shaft and planet wheel, this structure is general mode, and purposes is more extensive.But this structure there will be the needle roller play, constantly impact gear and pad and cause the cracked of gear pad, destroy the whole limit planetary gear speed reducing mechanism of taking turns.On planet wheel shaft, fluting causes the injury to axle itself simultaneously, makes the strength decreased of planet wheel shaft, affects whole service life.Therefore, develop a kind of rational in infrastructure, service-strong cantilever planet gear reducing mechanism, prevent that needle roller from being necessary to the impact of gear pad and the intensity of raising planet wheel shaft
.
The model utility content
The purpose of this utility model be to provide a kind of compact structure, good reliability, easy maintenance, vehicle drive axle cantilever planet gear reducing mechanism.
The utility model achieves the above object by the following technical programs: vehicle drive axle cantilever planet gear reducing mechanism comprises: gear pad, needle roller, bolt, plain washer, planet wheel shaft, straight pin, pad, planet wheel, planetary wheel carrier; The planet wheel shaft interference is on planetary wheel carrier, and pad is arranged between planet wheel and planetary wheel carrier, and the gear pad is arranged on planet wheel shaft, and bolt is packed into by plain washer in the middle part of gear pad and planet wheel shaft.Be provided with straight pin between gear pad and planet wheel shaft.Be provided with needle roller between planet wheel shaft and planet wheel.
The utility model can reach following good effect after adopting technique scheme: effectively improved planetary gear speed reducing mechanism cantilever planet wheel maintainability, prevented the impact of needle roller to the gear pad, improved the intensity of planet wheel shaft.This mechanism structure compactness, good reliability, easy maintenance.
The accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model vehicle drive axle with the cantilever planet gear reducing mechanism.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Vehicle drive axle cantilever planet gear reducing mechanism, comprise: gear pad 1, needle roller 2, bolt 3, plain washer 4, planet wheel shaft 5, straight pin 6, pad 7, planet wheel 8, planetary wheel carrier 9, pass through special tooling, with press equipment by the planet hole of planet wheel shaft 5 force fit planetary wheel carriers 9, needle roller 2 use butter are bonded at uniformly to the inner hole wall of planet wheel 8, block needle roller 2 with pad 7 and gear pad 1 at two ends, planet wheel hole, needle roller 2 will be housed, the planet wheel component that gear pad 1 and pad 7 form, be inserted in planet wheel shaft 5, behind gear pad 1 use straight pin 6 location, bolt 3 and plain washer 4 will be kept off to pad 1 to be fixed on planet wheel shaft 6, install successively each planetary pinion, this cantilever planet wheel slowing-down structure has assembled.
When work, needle roller 2 between planet wheel shaft 5 and planet wheel 8 is enclosed between gear pad 1 and pad 7, gear pad 1 is due to architecture advances, thickness increases, the play of needle roller 2 is difficult to be corrupted to gear pad 1, gear pad 1 use straight pin 6 is positioned on planet wheel shaft 5, can not rotate, and has guaranteed the stationarity of part running.
The utility model has improved planetary gear speed reducing mechanism cantilever planet wheel maintainability effectively, has prevented the impact of needle roller to the gear pad, has improved the intensity of planet wheel shaft.This mechanism structure compactness, good reliability, easy maintenance.
