Fixing connecting device used for bullet train high speed bogie bearing rotor

Abstract

The invention discloses a fixing connecting device used for a bullet train high speed bogie bearing rotor. The fixing connecting device includes a connecting assembly and a nipper. The connecting assembly includes two vertically placed force bearing plates. The top ends of the two force bearing plates are provided with multiple connecting rods. The bottoms of the two force bearing plates are provided with multiple limiting frames. The tops of the multiple limiting frames are provided with multiple squared hoop plates. The side walls of the multiple hoop plates are provided with multiple fixingholes. The side wall of the top end of the nipper is provided with multiple limiting holes. During using, firstly, through a nipper mouth inside the nipper, a user clamps the nipper on a rotation shaft transmission bar stably; through arc-shaped frame grooves in the bottoms of the force bearing plates, a rotor of the rotation shaft is fixed. Each force bearing plate is divided into two layers. When one of the force bearing plate is damaged, the other bearing plate can work continuously, so that the fixing connecting device is given better fault tolerance; the force bearing plates and the connecting rods are fastened through a bolt, and better stability is supplied to the fixing connecting device.

Description

technical field [0001] The invention relates to a fixed connection device, more precisely, a fixed connection device for a high-speed bogie bearing rotor of a train. Background technique [0002] There are certain defects in the design of the existing fixed connection device for the bearing rotor of the high-speed bogie of the motor car. First, the structure of the ordinary fixed connection device for the bearing rotor of the high-speed bogie of the motor car is complex, and the installation on the large bogie The disassembly process is relatively cumbersome. When the bogie fails, it is not conducive to timely disassembly and maintenance. Secondly, the fixed connection device of the high-speed bogie bearing rotor of ordinary trains adopts a single-layer connection structure. When a single force plate is damaged When , the work will be affected immediately, which is highly restrictive. Contents of the invention [0003] The invention mainly solves the technical problems ex...
