Double-chain double-shaft gear bearing transmission structure of three-dimensional garage chain shifting plate

Abstract

The invention relates to a vertical circulation type three-dimensional garage, in particular to a double-chain double-shaft gear bearing transmission structure of a three-dimensional garage chain shifting plate. The structure comprises a front rack, a rear rack, the chain shifting plate and a transmission shaft, an output shaft of a driving device is provided with a first chain wheel, the output shaft is connected with one end of a driving shaft through a first coupler, a second chain wheel is mounted at the other end of the driving shaft, the driving shaft is connected with the rear rack through a first bearing seat, and the driving shaft is parallel to the transmission shaft; a third chain wheel and a fourth chain wheel which are arranged on the transmission shaft are respectively transmitted with the first chain wheel and the second chain wheel through a transmission chain, the two ends of the transmission shaft are respectively provided with gears, the gears are engaged with an inner gear ring of an inner gear type slewing bearing, the inner end face of the inner gear ring is provided with the chain shifting plate, and the outer ring of the inner gear type slewing bearing is respectively fixedly connected with the front rack and the rear rack. According to the structure, the inner gear type slewing bearing is adopted, so that the diameter and the number of teeth of the chain shifting plate are increased, the sliding of a roller of a lifting chain in the chain shifting plate is reduced, and the service life of the chain shifting plate is prolonged.

Description

technical field [0001] The invention relates to a three-dimensional garage of vertical circulation type, in particular to a double-chain double-shaft gear bearing transmission structure of a shifting plate of a three-dimensional garage. Background technique [0002] The vertical circulation type three-dimensional garage includes a front frame, a rear frame, a drive shaft, a sprocket, a lifting chain, a drive mechanism, a vehicle-loading plate and a control mechanism, and an entrance and exit are arranged at the bottom of the front end of the front frame. Two drive shafts are horizontally installed on the upper and lower parts of the front frame and the rear frame respectively, and the two ends of the drive shafts are equipped with a chain plate, which drives the lifting chain to do reciprocating circular motion, and the car plate is installed on the lifting chain. Due to the small number of teeth on the chain plate, the pitch of the lifting chain is roughly such that the rol...

AI Technical Summary

Problems solved by technology

Due to the small number of teeth on the chain plate, the pitch of the lifting chain is roughly such that the rollers of the lifting chain slide in the chain plate, resulting in large wear and tear on the chain plate, inner and outer guide rails, and large noise. The damage of the chain plate; after increasing the diameter and the number of teeth of the chain plate, the chain plate is prone to deformation, causing the lifting chain to fall off the chain
