Reciprocating-type hydraulic transmission coupling

Abstract

The invention provides a reciprocating-type hydraulic transmission coupling, which comprises a hydraulic control circuit, transmission oil and a main machine; the main machine comprises a shell, a machine core, a transmission shaft a and a transmission shaft b; the shell consists of a machine base, a front cover, a rear cover and an end cover; bearings c are arranged in the rear cover; a bearing a and a bearing b are arranged in the front cover; the transmission shaft a is arranged in the bearings c, and the transmission shaft b is arranged in the bearing a and the bearing b; the machine core consists of a cylinder body, a plunger, a cam, a slipping boot and a return stroke ring; the plunger is arranged along the radial direction in the cylinder body; an eccentric circular hole is formed in the inner side of the cam; the slipping boot is contacted with the cam and is hinged with the plunger; the return stroke ring is arranged in the eccentric circular hole in the cam. The coupling has starting and overload protection ability, is high in transmission efficiency and is easy to control; when magneto-rheological fluid is used as the transmission oil, the reciprocating-type hydraulic transmission coupling provided by the invention also has the advantages that the control sensitivity is high, and automatic computer control can be easily realized.

Description

Technical field [0001] The invention belongs to the technical field of hydraulic transmission, and particularly relates to a reciprocating hydraulic transmission coupling. The invention is a reciprocating hydraulic transmission coupling realized by improving the existing reciprocating pump and hydraulic motor technology. Background technique [0002] Fluid coupling, also known as fluid coupling, is a non-rigid coupling, which is widely used in metallurgical equipment, mining machinery, power equipment, chemicals, automobiles, ships and other fields. [0003] The hydraulic coupling has the following structure. Its pump wheel and turbine form a closed working chamber that allows liquid to circulate. The pump wheel is mounted on the input shaft and the turbine is mounted on the output shaft. When the power machine drives the input shaft to rotate, the liquid is thrown out by the centrifugal pump wheel. After this high-speed liquid enters the turbine, it drives the turbine to rotate, ...

AI Technical Summary

Problems solved by technology

However, due to the frictional resistance generated by the flow, the transmission oil is easy to heat up and the oil temperature is high, so the energy loss is large and the transmission efficiency is low

Moreover, the hydraulic coupling is not easy to control the load torque and speed, the control sensitivity is low, and the response time is long

Therefore, these defects of the hydraulic coupling limit its application range
