Abstract
The utility model discloses a five-axis drive planet frame of a planet speed reducer, which is a single-sheet type planet frame, comprising a planet frame, a planet gear shaft and planet gears, wherein five axial holes are evenly distributed on the circumference of the planet frame, five planet gears (4) are respectively installed in the axial holes of the planet frame through the planet gear shaft (2), and a planet frame center hole is an involute gear splined hole, an output shaft (1) is installed on the involute gear splined hole of the planet frame through spline. The planet frame has low processing difficulty, and can increase the transmission efficiency of the speed reducer by times.
Description
Technical field
The utility model relates to the planet carrier of planetary speed reducer, is specifically related to a kind of five shaft drive planet carriers of planetary speed reducer.
Background technique
At present, the planet carrier of traditional planetary speed reducer is combined by three planet wheel shafts, three planet wheels and biplate integrated type usually, this biplate monolithic construction not only in the processing process difficulty of processing big, occur easily in the course of working scrapping, be unfavorable for the saving of cost, unfavorable to market competition, and in assembly process, also be difficult to install, its precision can not guarantee that transmission efficiency does not satisfy the demand in market.
Summary of the invention
The purpose of this utility model is: a kind of five shaft drive planet carriers of planetary speed reducer are provided, and this planet carrier difficulty of processing is low, and can also improve several times to the transmission efficiency of speed reducer.
Technical solution of the present utility model is: this planet carrier is the one chip planet carrier, comprise planet carrier, planet wheel shaft and planet wheel, five axis holes evenly distribute on the circumference of planet carrier, five planet wheels are installed in the axis hole of planet carrier by planet wheel shaft respectively, the planet carrier center hole is the involute cylindrical gear spline hole, and output shaft is installed on the involute cylindrical gear spline hole of planet carrier by spline.
In the five shaft drive planet carriers of planetary speed reducer of the present utility model, be provided with needle bearing between planet wheel and the planet wheel shaft.
In the five shaft drive planet carriers of planetary speed reducer of the present utility model, planet wheel engagement sun gear and ring gear.
Five planet carrier volumes of the present utility model are little, in light weight, speed ratio big, noise free, compact structure, transmission is accurate, operates steadily, and load is even, bearing capacity is big, the transmission ratio height, good airproof performance is under the equal volume situation, its bearing capacity is 4 to 5 times of other speed reducer bearing capacity, and max. output torque can reach 6000N*M.
