The novel planetary gear box is characterized in that the inner-ring thrust bearing bush (6) and the outer-ring thrust bearing bush (7) form constraint on rotation and revolution of a planetary gear assembly; in the constraint, three planetary gear assemblies which are respectively composed of the planetary gear shaft (8) and the planetary gear (10) are uniformly distributed; the output sun gear (11) completes transmission output by virtue of the connecting toothed sleeve (12) and the output shaft (13); and the output sun gear (11) is located and fixed by the three planetary gears (10) which are uniformly distributed.
Description
Technical field
The utility model relates to epicyclic gearbox, is specifically related to a kind of novel epicyclic gearbox.
Background technique
The setting type of common planetary pinion transmission all belongs to the NGW type, and promptly basic building block is by two sun gears, and several planet wheels and pivoted arm are formed, and the output sun gear is through axle and bearing fixing.Because traditional epicyclic gearbox has adopted planet carrier; For avoiding too high planet carrier rotating speed to cause stirring lubricant oil; Thereby cause the decrease in efficiency of power consumption penalty and transmission device, the rotating speed of planet carrier is restricted in traditional epicyclic gearbox, has influenced whole output speed.
Summary of the invention
The purpose of the utility model is need be through axle and bearing fixing to traditional epicyclic gearbox output sun gear; And overall performance receives the shortcoming of planet carrier restriction; A kind of novel and epicyclic gearbox that efficient is high is provided; Promptly constitute the kinematic constraint of planetary wheeling assembly, and three planet wheels in the planetary wheeling assembly can play the effect of accurate location and fixing output sun gear through ring thrust bearing shoe in installing and outer shroud thrust bearing shoe.Owing to adopted three equally distributed planetary wheeling assemblies and adopted thrust bearing shoe to substitute traditional planet carrier, so epicyclic gearbox has the advantage that running noises is little, efficient is high and velocity ratio is bigger.
The technological scheme of the utility model is:
A kind of novel epicyclic gearbox; Comprise casing 1, poly Vbelt wheel 2, input shaft 3, spheric roller bearing 4, lubricant pipe 5, interior ring thrust bearing shoe 6, outer shroud thrust bearing shoe 7, planet pin 8, input sun gear 9, planetary pinion 10, output sun gear 11, connect tooth cover 12, output shaft 13, it is characterized in that planet pin 8 and planetary pinion 10 constitute planetary wheeling assembly; The constraint of interior ring thrust bearing shoe 6 and 7 formation planetary wheeling assembly rotations of outer shroud thrust bearing shoe and revolution; In this constraint, be uniform-distribution with three same planetary wheeling assemblies that constitute by planet pin 8 and planetary pinion 10, revolve round the sun around input sun gear 9 and output sun gear 11 in the time of the planetary wheeling assembly rotation; Output sun gear 11 is accomplished transmission output through connecting tooth cover 12 with output shaft 13; Owing to be uniform-distribution with three planetary pinions 10, output sun gear 11 is by three planetary pinions, 10 location and fixing.
The utlity model has following advantage:
1) the utility model velocity ratio is bigger.Because thrust bearing shoe can bear higher rotation speed, this epicyclic gearbox velocity ratio is bigger.
2) running noises is little.Owing to be that three equally distributed planetary wheeling assemblies revolve round the sun around sun gear, so sun gear is stressed evenly, running noises is little during gear-box work.
3) transmission efficiency is high.Because no traditional planet carrier, the efficient of this epicyclic gearbox is higher.
