Abstract

The invention discloses an expansion bushing buffering coupler which comprises a torque input end sleeve and a torque output end sleeve connected with the torque input end sleeve. The torque output end sleeve is in splined connection with a driven shaft. An inner adapter sleeve and an outer adapter sleeve sleeving the inner adapter sleeve are arranged in the torque input end sleeve. The inner adapter sleeve is in splined connection with a driving shaft. The outer adapter sleeve is in splined connection with the torque input end sleeve. The inner adapter sleeve is in conical fit with the outer adapter sleeve. The end, close to the torque input end sleeve, of the inner adapter sleeve is provided with a radial convex plate which is provided with connecting bolts extending into the outer adapter sleeve. The expansion bushing buffering coupler is simple in structure, reliable in use, higher in applicability and capable of being applied to the working conditions that torque and impact are large and non-periodic frequent reversing exists.

Description

technical field

[0001] The invention belongs to the technical field of shaft couplings, in particular to an expansion sleeve buffer coupling. Background technique

[0002] A coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the functions of buffering, damping and improving the dynamic performance of the shafting. A general coupling consists of two halves, which are connected to the driving shaft and the driven shaft respectively. In the case of high speed, heavy load and impact, in order to achieve centering and transmit large impact torque, the drive shaft and driven shaft are mostly connected to the coupling by involute spline connection. However, affected by the size of the structure, the spline size on the drive shaft on the drive shaft is often small (such as hydraulic motors), and th...
