Design method of a slider-type cross cardan shaft used for high torque

Abstract

In order to improve the lubricity of the cross cardan shaft and reduce wear and bearing capacity, the present invention provides a design method for a slider-type cross cardan shaft used for high torque, which includes the first universal joint yoke and the second joint yoke connected to each other. Two universal joint yokes, the first universal joint yoke extends into the depression at the left end of the second universal joint yoke through the protrusion at the right end and connects with the bottom surface of the depression; and the second universal joint yoke is connected to the bottom surface of the depression; The neck diameter of a universal joint yoke is larger than the body diameter; a groove for placing lubricant is arranged on the bottom surface of the recessed part. In the present invention, lubricant is provided between the contact surfaces of the universal joint yokes, which reduces wear and improves the service life, and at the same time increases the diameter of the neck of the first universal joint yoke, so that the cross cardan shaft has High bearing capacity.

Description

technical field [0001] The invention relates to a design method of a slider-type cross cardan shaft used for high torque. Background technique [0002] The cross cardan shaft is a widely used mechanical component in the rolling equipment of the metallurgical industry. It is mainly used to transmit the power and motion of two transmission shafts that are not on the same straight line, but the cross cardan shaft of this kind is adapted to connect with each other. There is no lubricating facility between the two forks, and the wear and tear of the high-speed and frequent-running fork is serious, which shortens the service life, and the diameter of the neck of the first universal joint yoke in the cross cardan shaft is small, and the load-carrying capacity Low, prone to breakage. Contents of the invention [0003] The purpose of the present invention is to provide a design method for a slider-type cross cardan shaft used for high torque, so as to improve its lubricity and red...
