Abstract
The utility model relates to an elastic coupler of a safety pin, which is characterized in that a pin penetrates through a boss of a semi-coupler I to be embedded in a sliding bearing in the elastic sleeve fixedly connected with a semi-coupler II, the pin is twisted with a nut, the semi-coupler I is tightly twisted with the semi-coupler II by the but; the semi-coupler I is connected with a drive motor, the semi-coupler II is connected with a working end machine, the semi-coupler II and the working end machine are fixed by the safety pin. The drive motor and the working end are connected by the safety pin, when the load of the working end exceeds the given value of the safety pin, the safety pin is cut off because of overload, and then a driving end and the working end are separated, thereby protecting the drive motor and the working end machine (such as a speed reducer and the like), and effectively solving the problem that the elastic coupler cannot realize the protection of mechanical torsion overload.
Description
Technical field
The utility model relates to the safety pin elastic coupling flexible coupling, is mechanical type torque overload protection coupling.
Background technique
Existing elastic coupling flexible coupling seldom has mechanical type safety protection mode, can not protect the working end machinery very effectively.And torque limiter limits to its application area owing to cost an arm and a leg.Therefore need a kind of practicality and effective safety pin elastic coupling flexible coupling.
Summary of the invention
In order to realize that elastic coupling flexible coupling has the mechanical type safety protection device, protect the working end machinery effectively, the purpose of the utility model is to provide a kind of safety pin elastic coupling flexible coupling.It is applicable to needs the power transmission of torque protection occasion.
The purpose of the utility model realizes through following technological scheme:
A kind of safety pin elastic coupling flexible coupling comprises half-coupling I, nut, pin, elastic sleeve, sliding bearing, half-coupling II, safety pin.Pin passes in the sliding bearing in the elastic sleeve that half-coupling I boss embeds and half-coupling II is fixed, and pin is rotary with nut, with nut half-coupling I and half-coupling II is tightened; Half-coupling I is connected with drive motor, and half-coupling II is connected with the working end machinery, and with safety pin fixedly half-coupling II and working end machinery.
The utility model has the advantages that:
The utility model links together half-coupling II and working end machinery through safety pin; During the drive motor running; When the machinery load of working end surpassed the setting value of safety pin, safety pin was sheared because of overload and is broken off, and drive end and working end are thrown off; Thereby protection drive motor and working end equipment (like retarder etc.), solve elastic coupling flexible coupling effectively and can't reach the problem that the mechanical type torque overload is protected.When restarting, equipment can work on behind the replacing safety pin.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Embodiment
In conjunction with accompanying drawing, the technological scheme of the utility model is further described again:
As shown in Figure 1, a kind of safety pin elastic coupling flexible coupling comprises half-coupling I 1, nut 2, pin 3, elastic sleeve 4, sliding bearing 5, half-coupling II 6, safety pin 7.Pin 3 pass half-coupling I1 boss embed with the fixed elastic sleeve 4 of half-coupling II 6 in sliding bearing 5 in; Pin 3 is rotary with nut 2; With nut 2 half-coupling I 1 and half-coupling II 6 are tightened; Half-coupling I 1 is connected with drive motor, and half-coupling II 6 is connected with the working end machinery, and with safety pin 7 fixedly half-coupling II 6 and working end machinery.
Half-coupling I 1 is connected with drive motor, and half-coupling II 6 is connected with working end machinery (like speed reducer etc.), and moment of torsion passes to the working end machinery through half-coupling I 1, pin 3, elastic sleeve 4, half-coupling II 6, safety pin 7 successively.Behind torque overload, safety pin 7 is from half-coupling II 6 and the fracture of machinery input shaft joint, working end, and the working end quits work, and has solved elastic coupling flexible coupling and can't reach the problem that the mechanical type torque overload is protected.When restarting, with resuming work after the safety pin taking-up replacing of cutting off.
