Abstract
It the utility model is related to a kind of small speed reducing ratio high accuracy planetary reducer, belong to reductor equipment technical field, including input shaft and output shaft, adpting flange, input shaft one end connection sun gear are set with input shaft, sun gear engages with planetary gear, planetary gear is connected on roller excircle by needle roller, and on adpting flange, planetary gear engages with rotation ring gear for roller one end, ring gear connection output shaft is rotated, the gearratio between output shaft and input shaft is 1:2.The structure allows the accurate planetary reducer to realize low back clearance, gearratio=2, and going for transmission system needs low back clearance, the application scenario of small speed reducing ratio.
Description
Technical field
A kind of small speed reducing ratio high accuracy planetary reducer is the utility model is related to, belongs to reductor equipment technical field.
Background technology
Accurate planetary reducer has many merits such as small size, high pulling torque, high speed reducing ratio, low back clearance, gradually extensively should
For elaborate servo transmission field.But existing accurate planetary reducer speed reducing ratio is generally higher than 3, it is difficult to accomplish smaller deceleration
Than.When the low back clearance of transmission system needs, small speed reducing ratio, the accurate planetary reducer of tradition will be difficult to meet wanting for transmission system
Ask.
Utility model content
Deficiency of the prior art, the technical problems to be solved in the utility model are more than：A kind of small deceleration is provided
Than high-precision planetary reducer, low back clearance is realized, small speed reducing ratio, is solved the above problems.
Small speed reducing ratio high accuracy planetary reducer described in the utility model, including input shaft and output shaft, on input shaft
Adpting flange, input shaft one end connection sun gear are set with, sun gear engages with planetary gear, and planetary gear is connected to rolling by needle roller
On post excircle, on adpting flange, planetary gear engages with rotation ring gear for roller one end, rotation ring gear connection output
Axle, the gearratio between output shaft and input shaft are 1:2.
During work, power is transferred to sun gear by input shaft, and rotary motion is transferred to planetary gear, planetary gear by sun gear
Needle roller is provided between roller, planetary gear can rotate on roller, while planetary gear transmits rotary movement to rotation internal tooth
Circle, rotation ring gear export power by output shaft.
Described roller one end is pressed into the end face of adpting flange by interference fit.
It is to be rigidly connected between described rotation ring gear and output shaft.
Possessed beneficial effect is the utility model compared with prior art：
Small speed reducing ratio high accuracy planetary reducer makes the accurate planetary reducer by improving conventional planetary speed reducer structure
Low back clearance, gearratio=2 can be realized, going for transmission system needs low back clearance, the application scenario of small speed reducing ratio, ensures
The accuracy of transmission, make whole transmission system volume smaller, it is more efficient.

Embodiment
Embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in figure 1, small speed reducing ratio high accuracy planetary reducer includes input shaft 1 and output shaft 4, it is set with input shaft 1
There are adpting flange 2, the one end of input shaft 1 connection sun gear 3, sun gear 3 is engaged with planetary gear 6, and planetary gear 6 is connected by needle roller 7
On the excircle of roller 8, the one end of roller 8 is pressed into the end face of adpting flange 2 by interference fit, in planetary gear 6 and rotation
Gear ring 5 engages, and rotation ring gear 5 connects output shaft 4, and the gearratio between output shaft 4 and input shaft 1 is 1:2.
It is to be rigidly connected between rotation ring gear 5 and output shaft 4.
During work, the power of servomotor is transferred to sun gear 3 by input shaft 7, and rotary motion is transferred to by sun gear 3
Planetary gear 6, planetary gear 6 can be rotated by needle roller 7 on roller 8, while planetary gear 6 transmits rotary movement to rotation internal tooth
Circle 5, rotation ring gear 5 export power by output shaft 4.Low back clearance, gearratio=2 are realized, go for transmission system
Need low back clearance, the application scenario of small speed reducing ratio.
