Abstract
The utility model relates to a safety clutch, which is provided with a shaft sleeve, wherein a convex edge is arranged on one end of the outer edge of the shaft sleeve. The safety clutch is characterized in that a driving wheel is sleeved on the shaft sleeve close to the convex edge; a ball mounting sleeve and a spring pressing sleeve are arranged on the shaft sleeve adjacent to the driving wheel; balls are uniformly distributed and clamped between the driving wheel and the ball mounting sleeve; springs are uniformly distributed between the ball mounting sleeve and the spring pressing sleeve; an adjusting nut is arranged on the shaft sleeve which is positioned on one end of the spring pressing sleeve; and the safety clutch close to the ball mounting sleeve is also provided with a detecting head. The safety clutch has the advantages of simple structure, convenient processing, low cost, reliable operation, and capability of immediately separating a driving member and an operating member once the operating member is subjected to a moment which is more than a rated moment of a driving mechanism and then avoiding damage of important driving members due to overloaded external force.
Description
Technical field
The utility model belongs to a kind of mechanical transmission overload protection arrangement, particularly a kind of safety clutch.
Background technique
In mechanical transmission, the moment that is subjected to when workpiece is during greater than the rated moment of driving mechanism, in order to protect important transmission part because be subjected to the external force overload and be not damaged, uses clutch to connect driver part and workpiece usually.Existing clutch is common three kinds of roller type, wedge block type and click formulas, and these three kinds of clutch configurations are more complicated all, processes loaded down with trivial detailsly, thereby cost is higher.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of simple in structure, is convenient to processing, and cost is low, the safety clutch of reliable operation.
The utility model is achieved in that it has an axle sleeve, be provided with the convex edge at axle sleeve outer rim one end, its special way is: be set with driving wheel near the place, convex edge on axle sleeve, adjacent ball installation sleeve and the spring press-cover of being provided with on axle sleeve with driving wheel, all cloth holder has ball between driving wheel and ball installation sleeve, between ball installation sleeve and spring press-cover, be evenly equipped with spring, be positioned at spring press-cover one end and be provided with the adjustment nut on axle sleeve, this safety clutch also is being provided with detecting head near ball installation sleeve place.
Above-mentioned safety clutch, corresponding driving wheel place is provided with spacer on axle sleeve, to prolong the working life of axle sleeve.
Above-mentioned safety clutch is evenly equipped with ball hole on the end face of ball installation sleeve, corresponding each ball hole place is provided with conical socket respectively on the end face of driving wheel, and described ball is clamped between ball hole and the conical socket.
Above-mentioned safety clutch is positioned at adjustment nut outer end and also is provided with locking nut on axle sleeve.
The utility model has the advantages that: simple in structure, be convenient to processing, cost is low, reliable operation, in case when workpiece is subjected to moment greater than the rated moment of driving mechanism, can separate driver part and workpiece immediately, avoid important transmission part to be subjected to transshipping external force and damage.
