Hydrostatic coupler and automatic unloading mounting method of gear shaft thereof in working process

Abstract

The invention discloses a hydrostatic coupler and an automatic unloading mounting method of a gear shaft thereof in a working process. The coupler comprises a driving gear which is mounted on a poweroutput shaft of a prime mover and can rotate synchronously along with the power output shaft of the prime mover and a driven gear engaged to the driving gear, wherein an inner ring of the driven gearis elliptical, a hollow gear shaft which is connected to a working machine and drives the working machine to work is inserted into the inner ring of the driven gear, one end of the gear shaft is closed by a top cover and communicates to a pipeline of the working machine through a pressure supply device while the other end of the gear shaft is closed by a spring seat, and a spring mounted on the spring seat is connected to a piston in the gear shaft. The hydrostatic coupler disclosed by the invention achieves separation and union functions by matching the spring, the piston, a plunger hole anda plunger in the gear shaft, and can control connection or disconnection of the prime mover and the working machine by means of the pressure output by the working machine under the circumstance that the prime mover works continuously, so that the working machine is started or stopped.

Description

technical field [0001] The invention belongs to the field of power transmission and control, in particular to a method for automatically unloading and installing a hydrostatic coupling and its gear shaft in the working process in the field. Background technique [0002] The power between the traditional working machine (such as hydraulic pump, air compressor, etc.) , usually by stopping the prime mover or unloading the unloading valve to reduce energy consumption and prolong the life of the working machine. However, stopping the prime mover is not suitable for applications where the prime mover cannot be stopped or cannot be started and stopped frequently; although unloading of the unloading valve can ensure that the prime mover and the working machine run in a low-energy mode under unloaded conditions, the working machine is always working, and There is energy consumption. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
