High elastic rubber alloy shaft coupling device

Abstract

A high elastic rubber alloy shaft coupling, comprising a input shaft flange plate (1), elastic body (3), output coupling plate (5) and a output coupling cover (7). Inner toothing circular trapeziform tooth surface of the input shaft flange plate (1) and the external toothing trapeziform tooth surface of the elastic body (3) present an axial tapering slide fit, the elastic body (3) is bonded with the output coupling plate (5) into an integral body in a high strength. The elastic body (3) is a new type engineering composite material, the two-axial end face indent radian radius R is 40 to 60 millimeters, which is embedded with a steel wire ring (4), the torisonal vibration strength is intensified, the torsion angle is controlled in a moderate extent, which can adaptively adjust and compensate non-alignment error of shaft installment, non-counterbalance moment during power transmission is reduced greatly. Advantages of the shaft coupling are vibration damping, noise reduction, safe, reliable, highly effective, energy-saving, using life is long and installment is simple. The shaft coupling of the invention can be applied for power transmission systems of machinery warships, vehicles, petroleum, water conservancy and national defence weapons.

Description

technical field [0001] The invention belongs to the field of mechanical transmission in mechanical engineering, in particular to a high elastic rubber alloy shaft coupling. Background technique [0002] For a long time, various power devices such as ship propulsion systems, locomotives, excavators, cranes, heavy vehicles, compressors, generator sets, etc. in the mechanical transmission system have caused the main factor of torsional vibration of the shaft system due to the unevenness of the output torque. . After a long period of use, the elastic body of the elastic coupling of the German Vulkan company is prone to elastic fatigue damage of the rubber, the torsional vibration strength of the elastic body is reduced, and the maximum torque it can withstand is reduced, so that not only the high torque in the torsional direction The elasticity decreases, and the elasticity decreases in the axial, radial and angular directions, which cannot better compensate the misalignment er...

Problems solved by technology

After a long period of use, the elastic body of the elastic coupling of the German Vulkan company is prone to elastic fatigue damage of the rubber, the torsional vibration strength of the elastic body is reduced, and the maximum torque it can bear is reduced, so that not only the high torque in the torsional direction The elasticity decreases, and the elasticity decreases in the axial, radial and angular directions, which cannot better compensate the misalignment error of the shaft transmission mechanism due to the installation and operation process, and the change in the absorbency of the elastic body is affected by the use environment. Requires frequent replacement of elastic couplings
