Abstract
The utility model discloses a torque-limited belt pulley, which belongs to a part of a mechanical driver. The utility model solves the defects that: in the prior art, a specified bottleneck part needs to be designed to cope with high impact load, the arrangement of a safe clutch is complex, and models cannot be easily matched. The torque-limited belt pulley comprises a belt pulley and a transitional axle sleeve, the belt pulley is arranged on the outer part of the transitional axle sleeve, and a tapered roller bearing and a dustproof ring are arranged between the belt pulley and the transitional axle sleeve; a clutch disc and two nuts are arranged on the transitional axle sleeve at one side of the belt pulley, and the clutch disc is slidably connected on the transitional axle sleeve through a flat key; a disc spring is arranged between the clutch plate and the nuts, a thrust washer is arranged between the nuts, and a key slot is arranged in the transitional axle sleeve. The utility model is mainly used in the driver of mechanical equipment with high impact load.
Description
Technical field
The utility model belongs to a kind of parts of mechanical transmission, specifically, relates in particular to a kind of limit square belt pulley.
Background technique
In the structural design that has greater impact load mechanized equipment, generally speaking, selecting to damage the back in its transmission system changes and the relatively low part of cost easily, and it is designed to weak link, it can be easy to damage when equipment is subjected to greater impact load, thereby the disconnection Transmitted chains is realized safety protection to other component with this; The method that also has a kind of most convenient, be that the safety clutch that can either avoid part of damage can recycle again is set in transmission system, but, the many pattern outputs of existing safety clutch with sprocket wheel, gear or coupling, safety clutch by standard design may not be complementary with specific machinery, and because practical application is fewer, buying is also difficult.
Summary of the invention
To need specialized designs weak link part to deal with greater impact load in the prior art in order solving, the defective that safety clutch more complicated, model are not easy to mate to be set, the utility model provides a kind of limit square belt pulley.
The utility model is achieved through the following technical solutions:
A kind of limit square belt pulley comprises belt pulley and transition axle sleeve, and belt pulley is enclosed within transition axle sleeve outside, and the transition axis of belt pulley one side puts and is provided with clutch-plate and nut, and clutch-plate is slidingly connected at transition axis by flat key and puts; Be provided with belleville spring between clutch-plate and the nut, be provided with keyway in the transition axle sleeve.
Be provided with tapered roller bearing between belt pulley and the transition axle sleeve.Belt pulley and transition axis inner room are provided with dust ring.Transition axis puts and can be provided with two nuts, is provided with thrust washer between the nut.
Compared with prior art, the beneficial effects of the utility model are: be provided with tapered roller bearing between belt pulley and the transition axle sleeve, replace the friction that radially slides in the existing safety clutch in the mode of rolling friction, reduced wearing and tearing, convenient lubricated, the circular runout precision keeps easily; Simple in structure, be output as belt pulley and can directly pack on the motor shaft, easy to use.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Belt pulley in the drawings, 1; 2, transition axle sleeve; 3, dust ring; 4, tapered roller bearing; 5, clutch-plate; 6, belleville spring; 7, thrust washer; 8, nut; 9, keyway; 10, flat key.
A kind of limit square belt pulley comprises belt pulley 1 and transition axle sleeve 2, and belt pulley 1 is enclosed within transition axle sleeve 2 outsides, is provided with tapered roller bearing 4 and dust ring 3 between belt pulley 1 and the transition axle sleeve 2; The transition axle sleeve 2 of belt pulley 1 one sides is provided with clutch-plate 5 and two nuts 8, and clutch-plate 5 is slidingly connected on the transition axle sleeve 2 by flat key 10; Be provided with belleville spring 6 between clutch-plate 5 and the nut 8, be provided with thrust washer 7 between the nut 8, be provided with keyway 9 in the transition axle sleeve 2.
The utility model is at first fixedlyed connected with motor shaft or transmission shaft by keyway 9 in use; Regulate the amount of deformation of belleville spring 6 by nut 8, thereby change the pressure of belt pulley 1 and clutch-plate 5 end faces, regulate the maximum torque of transmission with this.
The utility model is when work, transition axle sleeve 2 passes to belt pulley 1 with moment of torsion, when 1 bringing onto load of belt pulley surpasses transition axle sleeve 2 and passes to the maximum torque that belt pulley 1 sets, belt pulley 1 will skid with clutch-plate 5 contacted end faces, play the effect of security insurance with this.
