The invention relates to a self horning type ball-and-socket synchronization universal coupler with a safety pin, and is applied to industries of non-ferrous metal, petroleum and the like. In the self horning type ball-and-socket synchronization universal coupler, a flange, an outer ring, a spline sleeve, a steel pipe and a shaft sleeve are connected into a whole by a steel ball through a spline shaft head; a spring is sleeved between spring seats; a needle roller bearing is arranged between a shaft sleeve and a shaft head of an overload protection device; the safety pin passes through a hole which is perpendicular to the shaft sleeve and the shaft head; a press plate is arranged on the end part of the shaft head; straight grooves in which shaft baffle rings are arranged are formed on the two end surfaces of the safety pin; and during overload, the safety pin is cut off, and the shaft head and the shaft sleeve are separated and can relatively rotate by means of the bearing arranged between the shaft head and the shaft sleeve to stop power transmission, so the coupler and other external equipment are protected to the greatest extent, equipment damage caused by overload is avoided, and economic losses due to failure electric appliance protection is reduced. The self horning type ball-and-socket synchronization universal coupler is high in safety coefficient and reliability, an important supplement to overload protection of electrical equipment, convenient to maintain and low in cost, the influence on the service life of the coupler due to excessive impact is effectively reduced, and the potential safety hazard can be eliminated to the greatest extent.
Description
technical field [0001] The invention relates to a coupling of a mechanical coupling device, specifically a self-returning ball cage synchronous universal joint with a safety pin used in non-ferrous metals and petroleum industries with large impact force, less frequent overload, and continuous work. coupling. Background technique [0002] In the prior art, an invention patent named "Self-homing Ball Cage Synchronous Universal Coupling" and patent number "ZL02265760.6" has been disclosed. It has a compact and reliable structure, easy installation, replacement and maintenance, and is anti-loose. And self-homing effect is obvious. However, when the impact of external equipment such as motors, reducers or mechanical work execution parts is too large, the coupling with this structure cannot automatically stop the transmission and cannot protect the equipment connected to the coupling, which seriously affects the reliability of the coupling. and the service life of associated equ...
