AI Technical Summary

Technical Problem

In multi-stage floating gear transmission systems, the cumulative axial clearance tolerance is difficult to control precisely, leading to complex assembly and easy operational failures, such as seizing or vibration and noise problems.

Method used

It adopts a combination structure of adjusting seat, mandrel and elastic element. The adjusting seat is screwed to the housing, and the elastic element pushes the mandrel to contact the floating gear. Combined with the scale line, the axial clearance can be accurately adjusted, simplifying the assembly process.

Benefits of technology

This eliminates the need for measurement and adjustment shims during assembly, reducing assembly difficulty, simplifying procedures, ensuring axial clearance meets design requirements, and preventing operational malfunctions.

Abstract

This invention discloses an axial clearance adjustment mechanism for a multi-stage floating gear transmission system, comprising an adjusting seat, a spindle, and an elastic element. The adjusting seat is adjustablely mounted on the housing of the multi-stage floating gear transmission system. A fastening structure is provided on the adjusting seat to fix it to the housing. The adjusting seat is screwed to the housing of the multi-stage floating gear transmission system, and the fastening structure is a locking nut. An adjusting cavity is provided inside the adjusting seat. The spindle passes through the adjusting seat, with one end passing through the adjusting cavity and extending into the housing, and the other end extending to the outside of the adjusting seat to form a measuring section. The elastic element, a spring, is disposed in the adjusting cavity and is used to elastically push the spindle into contact with the floating gear. This invention achieves accurate fulfillment of design requirements and eliminates the need for measurement and adjustment shims during assembly, effectively reducing assembly difficulty and assembly steps.
