Abstract
The invention discloses a planetary gear driven floating load-balancing mechanism of a sun gear. The floating load-balancing mechanism comprises an input shaft (1), an external solar gear (2), an open circular ring (3), six pins (4), six balls (5) and the like, wherein six pin holes (11) are formed in the cylindrical surface of the input shaft (1); an open slot (41) is formed in the end face of each of the six pins (4); the six balls (5) are placed from the pin holes (11) of the input shaft (1) to be contacted with a tooth socket (21) of the external gear (2); the open circular ring (3) is elastically opened and is stuck in the open slots (41) on the end faces of the six pins (4); and the input shaft (1) and the external solar gear (2) are driven to drive a planetary mechanism to implement floating load-balancing under the universal action of the six balls (5).
Description
Technical field
The present invention relates to the sun gear floating load balancing mechanism of Planetary Gear Transmission in machinery.A kind of sun gear floating load balancing mechanism specifically.Due to the floating load balancing mechanism of conventional art, its axial length is very long, and discontinuity between gear, bearing capacity reduces greatly.So force people to have to improve load balancing mechanism, occur to avoid uneven phenomenon of carrying with the bearing capacity improving Planetary Gear Transmission.
Background technique
In prior art, people adopt monodentate coupling or bidentate coupling as the sun gear floating load balancing mechanism of Planetary Gear Transmission.But due to the floating load balancing mechanism of prior art, its axial length is very long, so that cause the deficiencies such as volume is large, Heavy Weight, consumptive material, power consumption.And the sun gear floating load balancing mechanism of the Planetary Gear Transmission that the present invention relates to, the ball exactly in the inter-tooth slots of sun gear transmits universal load, substantially reduces axial length, and volume is little, lightweight, economize material, energy-conservation, solves this difficult problem.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of sun gear floating load balancing mechanism.This load balancing mechanism is made up of an input shaft, sun external gear, opening annulus, six pins and six balls etc.; The cylndrical surface of input shaft is arranged six pin pin-and-holes, the end face upper shed groove of six pins, six balls are put into and contact with the teeth groove of external gear from the pin pin-and-hole of input shaft, the elasticity of opening annulus can strut and be installed on the end face upper shed groove of six pins, drives input shaft sun gear to drive the work of planetary mechanism floating load balancing under the universal effect of six balls.This technology so far there are no reported in literature mistake.
Accompanying drawing explanation
Accompanying drawing 1 is sun gear floating load balancing mechanism shaft side figure of the present invention.
Embodiment
We carry out detailed description to the present invention by reference to the accompanying drawings below.Mode of execution: with reference to Fig. 1 load balancing mechanism be an input shaft (1), sun external gear (2), opening annulus (3), six pins (4) with six balls composition such as (5); Input shaft cylndrical surface is (1) arranged six pin pin-and-holes (11), six pins end face upper shed groove (41) (4), (5) six balls are put into and are contacted with external gear teeth groove (2) (21) from input shaft pin pin-and-hole (11) (1), opening annulus elasticity (3) struts and is installed on six pins end face upper shed groove (41) (4), drive input shaft (1) sun external gear (2) under the universal effect (5) of six balls, drive the work of planetary mechanism floating load balancing.
Most preferred embodiment: reference Fig. 1 is the best exemplifying embodiment of sun gear floating load balancing mechanism.It is same as the prior art that present embodiment does not state part.
