Abstract
The utility model provides an overload safety clutch. The safety clutch comprises a belt wheel and an output shaft and is characterized in that a clutch device is arranged on the output shaft, the clutch device comprises a flange disk, a spring, a spring base, a shaft, steel balls and flat keys, the belt wheel is sleeved on the shaft in an idling mode, the steel balls are distributed evenly on one side of the flange disk, the spring is installed on the other side of the flange disk, the spring is fixed by the spring base and a nut, and the flange disk and the shaft are connected and the shaft and the output shaft are connected though the flat keys. The overload safety clutch has the advantages that only the belt wheel of the clutch device which is arranged on the output shaft idles when failure of the output shaft occurs, so that the device can not be damaged due to overload.
Description
Technical field
The utility model relates to a kind of gearing field, a kind of overload clutch of concrete finger.
Background technique
When the torque of motor output was rotated by belt drive belt pulley, if output terminal breaks down, motor and output shaft still in running, will burn out motor or damage equipment because of overload like this.
The model utility content
The purpose of the utility model overcomes deficiency of the prior art exactly, and a kind of overload clutch is provided.
For realizing above-mentioned purpose, the technological scheme that the utility model adopted is achieved in that
A kind of overload clutch is provided, comprises belt pulley, output shaft, it is characterized in that: output shaft is provided with engaging and disengaging gear; Engaging and disengaging gear is made up of flange plate, spring, spring seat, axle, steel ball and flat key; Said belt bye is enclosed within on the axle, and an end of said flange plate is evenly distributed with the ball-type pit, in the ball-type pit steel ball is housed; Another side is equipped with spring, and spring is fixed by spring seat and nut; Flange plate is connected by flat key with output shaft with axle, axle.
The advantage of the utility model is: the engaging and disengaging gear of design on output shaft, and belt pulley idle running be can guarantee when output terminal breaks down, to have only, thereby can motor or damage equipment do not burnt out because of overload.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
Embodiment
Seeing also accompanying drawing, is a kind of overload clutch shown in the figure, comprises belt pulley 1, output shaft 2; Output shaft 2 is provided with engaging and disengaging gear, and engaging and disengaging gear is made up of flange plate 3, spring 4, spring seat 5, axle 6, steel ball 7, and belt pulley 1 sky is enclosed within on the axle 6; One end of said flange plate 3 is 4 ball-type pits of distribution evenly; 4 steel balls 7 are housed in the ball-type pit, and another side is equipped with 4 springs 4, and spring 4 is fixing by spring seat 5 and nut 8; Flange plate 3 is connected by flat key 9,10 with output shaft 2 with axle 6, axle 6.
Working principle and process: belt pulley 1 sky is enclosed within on the axle 6, and torque passes to flange plate 3 by the equally distributed steel ball 7 of end face, and flange plate 3 and axle 6, spools 6 are connected by flat key 9,10 with coupling shaft 2, and transmitting torque; The size of its output torque is regulated by spring 4; When output terminal 11 breaks down when being obstructed, torque increases, axial thrust load to the right of generation between belt pulley 1 and flange plate 3; Force flange plate 3 pressure springs 4 to move right; Steel ball 7 is separated from the ball-type pit and slides at flange plate 3, and axle 6 just stops operating, and reaches the effect of safe clutch.Fault after discharging resets steel ball 7, just can recover normal operation.
Preceding text have shown the detailed embodiment of the utility model, and are obvious, and those skilled in the art can carry out part and revise and change under the prerequisite of the utility model; The content of mentioning in the description of preceding text and the accompanying drawing is not to be the restriction to the utility model only as illustrative case; Have a kind of overload clutch of technical characteristics described herein, all fall into this patent protection domain.
