Abstract
Provided is a centre type torque overload protection device. The centre type torque overload protection device is characterized in that the structure of cooperation between a spherical surface and an inner conical surface is used for achieving transmission and separation of torque, the structure with a belleville spring is used for providing specific axial force, and multi-conical-surface sliding blocks are used for transmitting the axial force. The centre type torque overload protection device has the advantages that due to the fact that the structure of cooperation between the spherical surface and the inner conical surface is adopted, radial component force and axial component force can be generated in the process of operation, the proportion between the radial component force and the axial component force is fixed, the radial component force is used for achieving transmission of the torque, and the axial component force is used for achieving separation of the torque when the torque reaches the limit; the structure of the belleville spring is used for providing the specific axial force, and an axial movement space needed by separation is provided due to the compressibility of the belleville spring; due to the fact that a set of multi-conical-surface sliding blocks are arranged in the circumferential direction, the purposes that when a value of the axial displacement reaches a fixed value, the spherical surface is completely separated from the inner conical surface, and transmission force becomes zero can be achieved.
Description
technical field:
The present invention relates to mechanical equipment technical field, refer 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 losses 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 object of this invention 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 object of the invention is to realize as follows: a kind of centre lathe type torque overload protection device; it is characterized in that: this invention adopts 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.
The working principle of this invention 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; when moment of torsion surpasses a certain limit value, belleville spring is continued compression, and 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 invention has the beneficial effects as follows:
1. adopt sphere and inner conical surface cooperating structure, produce radial component and the axial thrust load of certainty ratio during work, radial component is realized the transmission of moment of torsion, and axial thrust load is realized the disengagement when 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, in the time of can realizing axial displacement and reach certain value, sphere departs from completely from inner conical surface, transmits power vanishing.
accompanying drawing explanation:
Fig. 1 is meshing engagement structure schematic diagram of the present invention;
Fig. 2 is disengagement structure schematic diagram of the present invention;
In figure: 1-bulb track bar; 2-belleville spring; 3-slide block.
embodiment:
With reference to accompanying drawing; a kind of centre lathe type torque overload protection device; it is characterized in that: this invention adopts 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.
The working principle of this invention 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; when moment of torsion surpasses a certain limit value, belleville spring is continued compression, and 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.
Specific works process, compressed butterfly spring 2 is by slide block 3, bulb track bar 1 is pressed in inner conical surface, during transmitting torque, sphere has relative movement tendency with the conical surface, when moment of torsion surpasses a certain limit value, axial thrust load between sphere and the conical surface is greater than the pressure of belleville spring 2, belleville spring 2 continues compressed, bulb track bar 1 moves backward, when bulb track bar 1 moves in figure the position shown in " overload is thrown off ", the axial force of belleville spring 2 can not be delivered on bulb track bar 1 again, sphere departs from completely from the conical surface, protection while realizing overload is thrown off.
