Structural Analysis of Steel Ball Type Universal Coupling Features Ball Ball Universal Coupling

The main characteristics of the ball-type universal joint include: input shaft, inner sleeve, cage, steel ball, jacket, output shaft, sealing cover, jacket and output shaft are monolithic structure; the open end of the jacket is provided with 40 ° chamfer; the shaft is connected between the input shaft and the inner sleeve;
Ball-type universal coupling has excellent performance such as full constant speed, self-determined rotation center, high transmission efficiency, absorption of vibration and impact, large swing angle, and high dynamic balance accuracy, and is mainly used for the steering axle of heavy-duty trucks. Device. It is mainly to solve the existing cross-country type of all-wheel drive structure of trucks, special military vehicles, such as the use of dual cross shaft coupling can not be more effectively adapted to the traffic on the informal road, can not meet people on trucks, special military vehicles Driving performance is high and comfort is required.
The ball type universal coupling discloses a coupling device for a common rail oil pump of a diesel engine. The coupling includes a coupling body, and a side of the coupling body is fixedly connected to a first metal elastic piece through a connecting device. The first metal elastic piece is provided with a connecting hole corresponding to the power output flange for powering the common rail oil pump; the other side of the coupling body is fixedly connected with a second metal elastic piece through a connecting device. The second metal elastic piece is provided with a connecting hole corresponding to the power input flange of the common rail oil pump of the diesel engine; the first metal elastic piece and the second metal elastic piece play the role of transmitting power on one hand, and the two metal elastic pieces are in the axial direction. Can make a certain range of deformation, in the radial direction can be a certain degree of bending, can better adapt to the axial and radial deviation between the two shafts, smooth transmission of power, thus reducing noise, improve the life of the pump At the same time, improve the quality of the diesel engine.
