Abstract
A torque overload safety protection device belongs to the technical field of transmission and safety protection. A convex surface of a convex conical friction disc and a concave surface of a concave conical friction disc are combined with each other, a plane bearing is mounted on a drive shaft, another plane bearing is mounted on a driven shaft, the drive shaft and the driven shaft are respectively arranged on two sides of the convex conical friction disc and the concave conical friction disc, annular press plates are mounted on the drive shaft and the driven shaft through sliding bearings respectively, tension bars are mounted between the two annular press plates, springs are mounted at the ends, extending out of one of the annular press plates, of the tension bars, and nuts are mounted at the ends of the springs on the tension bars. The torque overload safety protection device has the advantage that torque can be regulated conveniently.
Description
Technical field
The present invention relates to a kind of torque overload safety protection device, belong to transmission and security protection technology field.
Background technique
In the important transmission system of some transmissions; In order to prevent because torque overload and damage equipment or other security incident takes place; Generally the moment of torsion safety protection device to be set in transmission system; Although the existing moment of torsion safety protection device of crossing is not quite similar in principle and above the structure,, generally there is the uncontrollable defective of moment of torsion; Though the torque value that has can be regulated,, the defective that exists torque adjustment to bother.
Summary of the invention
The objective of the invention is to: though can regulate to uncontrollable defective of the existing moment of torsion of existing torque overload safety protection device or torque value; But; Have the defective of torque adjustment trouble, the present invention provides a kind of novel torque overload safety protection device.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of torque overload safety protection device; It comprises: driving shaft, sliding bearing, plane bearing, stayed mast, nut, spring, dome awl friction disk, friction plate, recessed circular cone friction disk, annular pressing plate, driven axle are formed; It is characterized in that: driving shaft vertically is fixed on the central position of dome awl wiping dish; Driven axle vertically is fixed on the central position of recessed circular cone friction disk; Described dome awl friction disk has identical tapering with convex-concave circular cone above the recessed circular cone friction disk; Riveted joint has a friction plate on the recessed circular cone of recessed circular cone friction disk, and the dome awl friction disk and the recessed circular cone friction disk convex-concave conical surface are close together mutually, at the driving shaft of convex cone friction disk and concave cone friction disk both sides and a plane bearing is installed above the driven axle separately; Respectively annular pressing plate is installed at driving shaft and above the driven axle through sliding bearing; Between two annular pressing plates, stayed mast is housed, spring is equipped with in the outstanding wherein end of an annular pressing plate of stayed mast, on the stayed mast of spring end, nut is housed.
Beneficial effect: the present invention is through the position of adjusting nut on pull bar; Just can reach the purpose of regulating pressure between two friction disks, thereby, but to the purpose of regulating friction torque between the two; So; The present invention not only has the effect of regulating moment of torsion, simultaneously, also has torque adjustment and has a few easily.
