Two-way overload protection transmission device

Abstract

The invention relates to a two-way overload protection transmission device. The two-way overload protection transmission device is characterized by comprising a driving wheel, an output shaft, pressure keeping springs and transition rollers; the driving wheel is used for inputting power; multiple grooves are peripherally and uniformly distributed in the peripheral surface of an inner hole of the driving wheel; one transition roller is mounted in one groove; the output shaft is arranged in the inner hole of the driving wheel; multiple concave cavities corresponding to the grooves one to one are peripherally and uniformly distributed in the outer periphery of the output shaft; the inner half parts of the transition rollers are positioned in the concave cavities; one pressure keeping spring is arranged in one concave cavity; one ends of the pressure keeping springs are ejected against the bottoms of the concave cavities, and the other ends of the pressure keeping springs are ejected against the transition rollers; and the sum of the diameters of the transition rollers and the lengths of the pressure keeping springs in limit compression is smaller than or equal to the depths of the concave cavities. The two-way overload protection transmission device is simple and compact in structure and convenient for installation, can realize reliable overload protection in the torque transfer process, and guarantees the equipment safety in overloading.

Description

technical field [0001] The invention relates to a two-way overload protection transmission device, which belongs to the technical field of mechanical transmission design. Background technique [0002] When electric motors, generators or other rotating mechanical equipment transmit energy or signals, they usually have a rated maximum transmission torque. For example, due to other failures such as load damage or mechanism blockage, it will cause the motor to burn out or cause large-scale failure. Therefore, a transmission device with overload protection is required. The existing transmission device with overload protection is usually complicated in structure, and it is difficult to realize two-way transmission. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a two-way overload protection transmission device, which has a simple and compact structure, is easy to install, can realize reliable o...
