Axial positioning device of spline transmission shaft

Abstract

The invention discloses an axial positioning device of a spline transmission shaft. The device comprises a limiting sleeve, an inner spline sleeve A, an inner spline sleeve B, and a clamp ring, the two inner spline sleeves sleeve the two ends of the spline transmission shaft, the right end of an inner spline hole of the inner spline sleeve B is provided with a clamp ring groove in the circumferential direction of the hole, the clamp ring is mounted in the clamp ring groove, the left end face of the clamp ring is in abut contact with the right end face of the spline transmission shaft, axial limiting of the spline transmission shaft can be achieved, the left end of the inner spline sleeve A is provided with an inner hole groove, the limiting sleeve s mounted in the inner hole groove, and can axially rotate in the inner hole groove, in the rotating process, the position relation of the limiting sleeve relative to the inner spline sleeve A comprises a locking position and an unlocking position, when the limiting sleeve rotates by the set angle, the limiting sleeve is clamped in the inner hole groove of the inner spline sleeve A, at the moment, the limiting sleeve is located on the locking position, the limiting sleeve is used for axially limiting the spline transmission shaft, in the rotating process, the positions outside the locking position are unlocking positions, and when thelimiting sleeve s located at the unlocking position, the limiting sleeve and the inner spline sleeve are detachable.

Description

technical field [0001] The invention relates to the technical field of transmission systems, in particular to an axial positioning device for a spline transmission shaft. Background technique [0002] The transmission shaft is a key part of the power transmission of the transmission system. Its performance plays a vital role in the function realization and reliability of the entire transmission system. In practical engineering applications, the transmission shaft has splines, transition fillets and lubrication holes. and other complex structural features. The axial positioning of the transmission shaft is an indispensable key link in the engineering design process. Under the condition of ensuring the function of the transmission shaft, it should also be easy to disassemble and have good maintainability. At present, the axial positioning of the transmission shaft is generally carried out by means of snap rings. This method requires the transmission system to have a large ope...

Problems solved by technology

[0003] As the transmission system develops towards the direction of high power density, its structural layout is compact and the space is small. At the same time, the transmission system generally adopts a modular design, and the components are related to each other. The transmission shaft is the main part connected between the components. The positioning method of the snap ring usually makes the transmission shaft difficult to disassemble, which seriously affects the disassembly efficiency of each component of the transmission system, and it is difficult to meet the maintenance conditions of the transmission system
