Self-centering jaw coupler with stepless adjustable connecting aperture

Abstract

The invention relates to a self-centering jaw coupler with a stepless adjustable connecting aperture, and belongs to the technical field of couplers. The coupler comprises a first sleeve body (1), a first clamping jaw spring body, a main body (4), a second clamping jaw spring body and a second sleeve body (7). The clamping jaw spring body is formed by sequentially staggering n clamping jaws and n springs into a ring, and sequencing and connecting the n clamping jaws and the n springs. A cross-shaped connecting body (44) on the main body (4) comprises a longitudinal connecting end and a transverse connecting end, so that the coupler can deflect in multiple dimensions, and a small amount of misalignment of two shafts can be tolerated. According to the self-centering jaw coupler with the stepless adjustable connecting aperture provided by the invention, through the mode that the multiple clamping jaws can concentrically move in the radial direction to enable a connecting shaft and the coupler to be automatically centered, the problem that two connecting axes do not coincide when an open single-opening coupler in clearance fit is tightened and fixed at present is solved, the self-centering jaw coupler with the stepless adjustable connecting aperture provided by the invention has the characteristic that a connecting hole is adjustable in a stepless mode, and the coupler can be suitable for connection of shaft diameters with multiple sizes, is beneficial to batch production and cost reduction, and has the advantages of simple and convenient installation, accurate centering of the axis position, wide applicable rotating speed range and the like.

Description

technical field [0001] The invention specifically relates to a self-centering jaw coupling with infinitely adjustable connection aperture, which belongs to the technical field of couplings. Background technique [0002] In production and life, most of the high-speed motors drive the driven parts to rotate, and the motor and the driven parts are connected by couplings to transmit torque. The quality of the shaft alignment between the motor shaft and the driven equipment directly affects the driven equipment And the running state of the motor, such as poor alignment, increased vibration, increased noise, damage to the mechanical seal, decreased efficiency of the follower, and increased energy consumption. Good alignment can reduce production loss, prolong the service life of equipment, slow down the failure of bearings and seals, reduce the vibration of equipment, reduce the wear of couplings, reduce maintenance costs, and reduce power consumption. [0003] Nowadays, in order...
