Abstract
A centre type torque overload protection device is characterized in that transmission and separation of torque are achieved through a matching structure of a spherical surface and an inner conical surface, and specific axial force is provided through a belleville spring structure and transmitted through multi-conical-surface sliding blocks. The centre type torque overload protection device has the advantages that the matching structure of the spherical surface and the inner conical surface is adopted, proportional radial component force and axial component force are generated in the work process, the radial component force achieves transmission of the torque, and the axial component force achieves separation when the torque reaches a limit; the specific axial force is provided through the belleville spring structure, and required axial movement space is provided for separation through the compressibility of a belleville spring; a set of the multi-conical-surface sliding blocks are arranged in the circumferential direction, so that the spherical surface is separated from the inner conical surface completely when the axial displacement reaches a certain value, and transmission force becomes zero.
Description
Technical field
The utility model relates to mechanical equipment technical field, refers in particular to a kind of centre lathe type torque overload protection device.
Background technique
In the evolution of drive technology, coupling is to connect the indispensable element of power equipment, and along with the development of industrial technology, production automation degree is more and more higher.In process of production because a variety of causes such as vibration for a long time, impact may make the component in manufacturing mechanism loosening; the phenomenons such as generation and other action component are stuck; cause whole system overload, the destruction of causing unrepairable, causes the loss such as equipment replacement, shutdown shut-down huge thus.Therefore, the overload protection problem attention that has caused people gradually.
In the processing of overload protection, what mainly consider is the overload trip gear of linkage member, makes moment of torsion can not continue to transmit.
Summary of the invention
The purpose of this utility model is to provide a kind of centre lathe type torque overload protection device, for meeting the demand of the Overloading protective coupling under different torque demands.
The purpose of this utility model realizes as follows: a kind of centre lathe type torque overload protection device, it is characterized in that: adopt sphere and inner conical surface cooperating structure to realize transmission and the disengagement of moment of torsion, adopt disk-shape spring structure that specific axial force is provided, adopt the slide block of many conical surfaces to transmit axial force, working principle is: compressed butterfly spring passes through slide block, bulb track bar is pressed in inner conical surface, the radial component that sphere contacts with the conical surface can transmitting torque, in the time that moment of torsion exceedes a certain limit value, belleville spring is continued compression, bulb track bar moves backward, when sphere departs from completely from the conical surface, the protection while realizing overload is thrown off.
Described sphere and inner conical surface cooperating structure, conical surface angle at 60 ° within the scope of 150 °.
The slide block of described many conical surfaces has the structure of two planes, two cylndrical surface and three conical surfaces, and wherein three conical surfaces are main stress surface.
The beneficial effects of the utility model are:
1. adopt sphere and inner conical surface cooperating structure, produce radial component and the axial thrust load of certainty ratio when work, radial component is realized the transmission of moment of torsion, and axial thrust load is realized the disengagement in the time that moment of torsion reaches restriction;
2. adopt disk-shape spring structure that specific axial force is provided, utilize the compressibility of belleville spring to provide simultaneously and throw off the required space that moves axially;
3. the slide block of circumferential directions conical surface more than a group, can realize axial displacement and reach certain value time, sphere departs from completely from inner conical surface, transmits power vanishing.
accompanying drawing explanation:
