Description

Plum blossom type expansion sleeve clamping type aluminum alloy coupling

Technical Field

The utility model relates to a shaft coupling technical field specifically is plum blossom mold bloated cover clamping mode aluminum alloy shaft coupling.

Background

The coupling is a mechanical part for coupling two shafts (a driving shaft and a driven shaft) of different mechanisms to rotate together to transmit torque. In the high-speed heavy-load power transmission, some couplings also have the functions of buffering and damping and improving the dynamic performance of a shaft system. The general coupling consists of two halves, which are connected to the driving shaft and the driven shaft, respectively.

Under the conditions of high speed, heavy load and impact, in order to realize centering and transfer of larger impact torque, an involute spline connection mode is mostly adopted when the driving shaft and the driven shaft are connected with the coupler. The traditional coupler is matched with a standard spline, when the spline is tight in size, the assembly is not easy, if the spline is hit hard, the internal bearing of a main engine is easily damaged, so that the hydraulic system is damaged early, when the spline is loose, enough tooth side gaps exist among the splines, the assembly is convenient, and under the condition of impact load, the spline is easily abraded. Under the working conditions of large impact load and frequent reversing, once the inner spline and the outer spline have tooth side gaps, the phenomenon of spline abrasion on a shaft or a hole can occur during working reversing.
