Modularized assemblable rolling electric rotation transmission device

Abstract

The invention discloses a modularized assemblable rolling electric rotation transmission device. The device comprises an upper cover plate, an upper support ring, a sealing cover plate, a first overlapping housing, a transmission module unit, a second overlapping housing, a fixed plate and a lower cover plate. The transmission module unit comprises a keeping rack rivet, a contact roll ball upper keeping rack, an inner conducive ring wire, contact roll balls, an inner conductive ring, an outer conductive ring, an outer conductive ring wire and a contact roll ball lower keeping rack. The outer conductive ring sleeves the inner conductive ring. Multiple contact roll balls are movably installed between the outer conductive ring and the inner conductive ring through the contact roll ball upperkeeping rack and the contact roll ball lower keeping rack. Each contact roll ball keeps relative rolling between the inner conductive ring and the outer conductive ring in the relative position, so contact transmission of the current is achieved. The sealing cover plate is installed on a fixed screw of the inner conductive ring. According to the invention, through rolling contact transmission, wear is low; service lifetime of the product is quite long; and by use of the modularization structure, the device is simple in structure, convenient to assemble, high in exchangeability and convenient to maintain.

Description

technical field [0001] The invention designs a socket device, and in particular relates to a modularly assembled rolling electric rotary transmission device. Background technique [0002] At present, the slip rings on the market use the sliding friction contact method for current transmission. After a certain number of rotations, the degree of wear between the contact points continues to increase, and the wear becomes more and more serious. On the one hand, it affects the contact resistance of the current signal. On the other hand, the contacts are more likely to wear through sliding contact, which in turn affects the service life of the product. . Contents of the invention [0003] In order to solve the above-mentioned defects in the prior art, the present invention provides a rolling electric rotary transmission device that can be assembled modularly. On the one hand, it adopts the contact mode of rolling friction, which greatly reduces the degree of wear during the rot...
