Universal flexible multi-functional coupling

Abstract

The invention relates to a universal flexible multi-functional coupling, which comprises two half coupling taper sleeves and a middle section, wherein the middle section comprises three jointing plates, an adjustable slip joint and a universal joint; the adjustable slip joint comprises a mandrel and a shaft sleeve sleeved on the mandrel; key slots are correspondingly reserved at the internal axial position of the shaft sleeve and the external axial position of the mandrel respectively; the shaft sleeve and the mandrel are fixed by slip keys in the key slots; the joint plate I is connected with a flange plate on the end part of the shaft sleeve; the flange plate at one end of the universal joint is connected with that on the end part of the mandrel; the flange plate at the other end of the universal joint is connected with the jointing plate II; the jointing plates II and III are connected; and the two half coupling taper sleeves are connected to the outsides of the jointing plates I and III respectively. The coupling has the advantages of great axial and angular compensation, high fatigue-durable torque, high-temperature resistance without deformation, high flexibility, low amplitude, low noise, short assembly and disassembly time, long service life and the like, and is the multifunctional coupling with high comprehensive performance.

Description

technical field [0001] The invention belongs to the field of shaft couplings, in particular to a universal flexible multifunctional coupling. Background technique [0002] As a motor to transmit power, the most common one is to connect the output shaft of the motor with the transmission shaft through a coupling, so that the power of the motor can be transmitted. However, the universal and diaphragm couplings used at home and abroad often cannot meet the technical requirements for high-temperature working conditions and high-temperature medium equipment in the use and installation of passive equipment. In metallurgy, petrochemical, petroleum Various equipment used such as: high temperature pump, rolling machine and various test platforms. When the temperature of the high-temperature medium pumped out by the high-temperature pump exceeds 200°C, the pump shaft is affected by the heat of the high-temperature conduction pump shaft, and the pump shaft is deformed, causing the dia...

Problems solved by technology

However, the coupling still has some shortcomings, such as: single use, can only be used between the fixed distance between the driving machine and the driven machine; the axial kink angle is small, the allowable speed is low, the fatigue torque is small, weak, large amplitude, and easy to deform under high temperature conditions; in addition, this type of coupling has high requirements for the accuracy of the distance between the end faces of the two shafts during installation, it is difficult to install and adjust, and it is time-consuming and laborious
