Description
Technical field
The utility model relates to gear drive, is specifically related to the two unsteady planetary gear mechanisms of a kind of two-stage.
Background technique
At present, domestic existing two unsteady planetary gear mechanisms are the load uniform distribution that makes three planet wheels, the tooth-like relocation mechanism that the overwhelming majority has adopted sun gear, planet carrier to float simultaneously, this pair of relocation mechanism rotary inertia is big, and accuracy of manufacturing requires high, make difficulty, on a small scale the manufacture cost height.
Summary of the invention
The purpose of this utility model be to provide a kind of accuracy of manufacturing require low, be easy to make, cost is low, noise is little, efficient is high, long service life, two unsteady planetary gear mechanisms of two-stage easy to maintenance.
The technological scheme that the utility model adopted is: the two unsteady planetary gear mechanisms of two-stage comprise input shaft, high-speed sun pinion, high-speed row star-wheel, high-speed row spider gear shaft, bearing, high-speed carrier, high speed internal gear, gear tie-plate, snap ring bolt, frame, low-speed sun pinion, low-speed planets, low-speed planets axle, low-speed carrier, low speed internal gear and top.In the high-speed carrier part, high-speed sun pinion and high speed internal gear are two to float, and in the low-speed carrier part, low-speed sun pinion and low speed internal gear are two to float.High speed internal gear and low speed internal gear all connect with the gear tie-plate with the gear engagement form, and are axially fixed on the gear tie-plate by the snap ring bolt, and the gear tie-plate is fixed on the frame.Input shaft radially connects with high-speed sun pinion with inside and outside tooth mesh form, the other end of high-speed sun pinion and three radially outer gearings of high-speed row star-wheel, high-speed sun pinion is by the top axial restraint, the high-speed row star-wheel by high-speed row spider gear shaft and bearing fixing on high-speed carrier, and with the high speed internal gear in mesh.High-speed carrier one end is fixed on the frame, the other end is fixed on the gear tie-plate, engagement in high-speed carrier and the low-speed sun pinion, low-speed sun pinion and low-speed planets outer gearing, low-speed sun pinion is by the top axial restraint, low-speed planets by low-speed planets axle and bearing fixing on low-speed carrier, and with the low speed internal gear in mesh, low-speed carrier one end is fixed on the gear tie-plate, and the other end is fixed on the frame.
During work, power source inputs to high-speed sun pinion by input shaft, exports low-speed sun pinion through the high-speed row star-wheel to by high-speed carrier then, exports working machine from low-speed sun pinion to through low-speed planets and low-speed carrier again, thereby finishes whole transmission process.
The utlity model has following advantage: the two-stage planetary mechanism all adopts the sun gear input, planet carrier output, and the two driving mechanisms that float of sun gear and internal gear, thus make the device fabrication required precision low, be easy to make, cost is low, and operational noise is little simultaneously, the efficient height, long service life, easy to maintenance.
