Abstract
The utility model discloses a kind of safety coupling with overload protection function, this safety coupling comprises motor side attachment portion and equipment end attachment portion, face-flange is provided with in motor side attachment portion, be provided with external tooth flange in equipment end attachment portion, face-flange is connected by safety pin with external tooth flange; In external tooth flange, be provided with bearings axle, external tooth flange is contained on bearings axle by bearing housing.Adopt this safety coupling can proterctive equipment, can not be damaged because of overload.
Description
Technical field
The utility model relates to a kind of smelter coupling, specifically a kind of safety coupling with overload protection function.
Background technique
In the industrial production, two axles (driving shaft and driven shaft) that coupling is used in connection different institutions make it jointly to rotate with the mechanical parts of transmitting torque.In the power transmission of high-speed overload, some coupling also has the effect of buffering, vibration damping and raising axle system dynamic performance.Coupling is made up of two halves, connects respectively with driving shaft and driven shaft.General power engine is mostly connected by means of coupling and working machine.Traditional coupling does not have overload protection function, and load can damage equipment, occur substantial equipment accident after exceeding setting moment of torsion.
Summary of the invention
The purpose of this utility model is to provide a kind of safety coupling with overload protection function, adopts this safety coupling can proterctive equipment, can not be damaged because of overload.
The purpose of this utility model is achieved through the following technical solutions:
A kind of safety coupling with overload protection function, it is characterized in that: this safety coupling comprises motor side attachment portion and equipment end attachment portion, face-flange is provided with in motor side attachment portion, be provided with external tooth flange in equipment end attachment portion, face-flange is connected by safety pin with external tooth flange; In external tooth flange, be provided with bearings axle, external tooth flange is contained on bearings axle by bearing housing.
In the utility model, the shearing diameter of safety pin and quantity obtain as required, and are checked by destruction test.Face-flange is connected by 6 safety pins with external tooth flange; 6 safety pins are evenly distributed on face-flange and external tooth flange circumferentially.The working speed of described safety pin is 500-1000 rev/min; The shearing diameter of safety pin is 4.95-5.05mm.The limit torque of described safety pin is 23875Nm.
In order to carry out overload protection to some special equipment, after namely load exceedes setting moment of torsion, fractureing by safety pin, plays the effect of proterctive equipment.
Compared with prior art, adopt this safety coupling can proterctive equipment, can not be damaged because of overload.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of safety coupling with overload protection function, see Fig. 1, this safety coupling comprises the motor side attachment portion 1 be connected with motor, the equipment end attachment portion 5 be connected with the equipment 8 that needs are protected, face-flange 2 is provided with in motor side attachment portion, be provided with external tooth flange 3 in equipment end attachment portion 5, face-flange is connected by safety pin 6 with external tooth flange; The shearing diameter of safety pin and quantity can calculate as required, and are checked by destruction test.Face-flange is connected by 6 safety pins with external tooth flange; 6 safety pins are evenly distributed on face-flange and external tooth flange circumferentially.The working speed of safety pin is 500-1000 rev/min; The shearing diameter of safety pin is 4.95-5.05mm.The limit torque of safety pin is 23875Nm.In external tooth flange, be provided with bearings axle 4, external tooth flange is sleeved on bearings axle by bearing 7.
In machine operation; after overload; once safety pin fractures; motor side attachment portion 1 in equipment, face-flange 2 and bearings axle 4 are linked to be an entirety; supported by bearing 7 between external tooth flange 3, form idle running, ensure that the equipment end attachment portion 5 of working end does not also fall down; so just can protect equipment, can not be damaged because of overload.
