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 the machinery.A kind of sun gear floating load balancing mechanism specifically.Because the floating load balancing mechanism of conventional art, its axial length is very long, and discontinuity between the gear, and bearing capacity reduces greatly.So force people to have to improve load balancing mechanism, to avoid the uneven bearing capacity that Planetary Gear Transmission occurs to improve phenomenon of carrying.
Background technique
In the prior art, people adopt monodentate coupling or bidentate coupling as the sun gear floating load balancing mechanism of Planetary Gear Transmission.But because 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 in the inter-tooth slots of sun gear transmits universal load exactly, has greatly shortened axial length, and volume is little, lightweight, economize material, energy-conservation, has solved 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 comprised of an input shaft, a sun external gear, an opening annulus, six pins and six balls etc.; Six pin pin-and-holes are set on the cylndrical surface of input shaft, the end face upper shed groove of six pins, six balls are put into from the pin pin-and-hole of input shaft and are contacted with the teeth groove of external gear, the elasticity of opening annulus can strut and be installed on the end face upper shed groove of six pins, drives the input shaft sun gear and 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.
Description of drawings
Accompanying drawing 1 is sun gear floating load balancing mechanism shaft side figure of the present invention.
Embodiment
Below we carry out detailed description to the present invention by reference to the accompanying drawings.Mode of execution: be an input shaft ⑴, a sun external gear ⑵, opening annulus ⑶, six pin ⑷ and six compositions such as ball ⑸ with reference to Fig. 1 load balancing mechanism; Six pin pin-and-holes (11) are set on the cylndrical surface of input shaft ⑴, the end face upper shed groove (41) of six pin ⑷, six ball ⑸ put into from the pin pin-and-hole (11) of input shaft ⑴ and contact with the teeth groove (21) of external gear ⑵, the elasticity of opening annulus ⑶ struts and is installed on the end face upper shed groove (41) of six pin ⑷, drives input shaft ⑴ sun external gear ⑵ and drive the work of planetary mechanism floating load balancing under the universal effect of six ball ⑸.
Most preferred embodiment: be the best exemplifying embodiment of sun gear floating load balancing mechanism with reference to Fig. 1.It is same as the prior art that present embodiment is not stated part.
