Description

A kind of drum-shaped tooth type friction coupling
Technical field
The utility model relates to a kind of coupling, is specially a kind of drum-shaped tooth type friction coupling.
Background technique
Coupling is that two axles (being driving shaft and driven shaft) that are used for connecting in the different institutions make it the mechanical parts of common rotation with transmitting torque.In the power transmission of high-speed overload, it is the effect of dynamic performance that some coupling also has buffering, vibration damping and raising axle.Coupling is made up of two halves, connects with driving shaft and driven shaft respectively.General power engine mostly links by means of coupling and working machine.
At present, conventional coupling is when work, because the moment of torsion that it transmitted often changes, when transmission power surpasses rated torque, driven coupling can not stop operating, thereby causes device to overload and be damaged, and Security is relatively poor, and transmitting torque is limited.
Summary of the invention
The utility model provides a kind of drum-shaped tooth type friction coupling, has solved defective of the prior art, and braking moment is big, and transmitting torque is big, and is safe.
Realize that the technological scheme that the utility model above-mentioned purpose is adopted is:
A kind of drum-shaped tooth type friction coupling comprises driving shaft, driven shaft, driving axle housing that is connected with driving shaft and the driven axle sleeve that is connected with driven shaft at least, and driving shaft transfers a torque to driven shaft through driving axle housing and driven axle sleeve; Driven axle sleeve is cylindric; Be set on the driven shaft, driving axle housing is stepped, and less one section of diameter is set on the driving shaft; One section outside that is enclosed within driven axle sleeve that diameter is bigger; Be provided with the enclosing cover that is fixedly connected with driving axle housing between driving axle housing and the driven axle sleeve, enclosing cover be circular and with the common circular chamber that forms of driving axle housing and driven axle sleeve, be provided with limit in the chamber and turn round device; Limit is turned round the regulator that device comprises intermeshing inner blade and outer gear piece at least and is used to regulate distance between the inside and outside gear piece; Wherein inner blade is fixed on the outer wall of driven axle sleeve, and outer gear piece is fixed on the inwall of driving axle housing, and regulator is fixed between enclosing cover and inner blade or the outer gear piece.
Inner blade and outer gear piece are circular, are provided with friction plate between the two.
Regulator comprises spacer, spring and bolt A; Spacer is positioned at chamber and is circular; Contact with inner blade or outer gear piece; Cover outward and be provided with two equally distributed through holes at least, bolt A is installed on outer cover and the end of bolt A is positioned at chamber through through hole, and spring is between bolt A and spacer.The external stability of enclosing cover is connected with nut, and bolt A is installed in the through hole through nut.As preferably, used spring is a belleville spring.
Enclosing cover is fixedly connected with driving axle housing through bolt B.
The drum-shaped tooth type friction coupling that the utility model provides has following advantage: the rated torque of this coupling can be regulated through regulator; When the transmitting torque of driving shaft surpasses rated torque; The inner blade that is provided with between driving axle housing and the driven axle sleeve skids with outer gear piece relatively; Thereby driven shaft is stopped operating, avoided device to be damaged the Security when guaranteeing to overload because of overload.When institute's transmitting torque is reduced to rated torque, no longer skid between driving axle housing and the driven axle sleeve, device recovers to run well.This drum-shaped tooth type friction coupling also has good stability, advantage that transmitting torque is big simultaneously.
Description of drawings
The structural representation of the drum-shaped tooth type friction coupling that Fig. 1 provides for the utility model;
Among the figure, 1-driving shaft, 2-driven shaft, 3-driving axle housing, the driven axle sleeve of 4-, 5-enclosing cover, 6-inner blade, the outer gear piece of 7-, 8-friction plate, 9-bolt A, 10-bolt B, 11-spacer, 12-spring.
Embodiment
The utility model is done bright in detail specifically below in conjunction with accompanying drawing.
The structure of the drum-shaped tooth type friction coupling that the utility model provides is as shown in Figure 1, turns round device by driving shaft 1, driven shaft 2, driving axle housing 3, driven axle sleeve 4, enclosing cover 5 and limit and forms.Driven axle sleeve 4 is cylindric, and the one of which end is set on the driven shaft 2, and with driven shaft 2 between be connected through spline; Driving axle housing 3 is stepped, and less one section of its diameter is loaded on the driving shaft 1 one section outside that is enclosed within driven axle sleeve 4 that diameter is bigger through the spline connecting sleeve.
Enclosing cover 5 is between driving axle housing 3 and driven axle sleeve 4; Enclosing cover 5 is circular and is fixedly connected with driving axle housing 3 through bolt B 10, and the chamber that the common formation of enclosing cover 5 and driving axle housing 3 and driven axle sleeve 4 one is circular is provided with in the chamber to limit and turns round device; Limit is turned round device and is made up of inner blade 6, outer gear piece 7, friction plate 8 and regulator; Inner blade 6 is meshing with each other with outer gear piece 7, and both are circular, friction plate 8 inner blade 6 and outside between the gear piece 7; Inner blade 6 is fixed on the outer wall of driven axle sleeve 4, and outer gear piece 7 is fixed on the inwall of driving axle housing 3.
Regulator is fixed between enclosing cover 5 and the interior or outer gear piece, is used to regulate the distance between the inside and outside gear piece.Regulator comprises spacer 11, spring 12 and bolt A9, and spacer 11 is positioned at chamber and for circular, contacts with inner blade or outer gear piece, is provided with two equally distributed through holes on the enclosing cover 5 at least, and in the present embodiment, through hole is provided with four.The external stability of enclosing cover 5 is connected with nut, and bolt A9 is installed in the through hole through nut, and the end of bolt A9 is positioned at chamber, and spring 12 is between bolt A9 and spacer 11, and in the present embodiment, used spring is a belleville spring.
The drum-shaped tooth type friction coupling that the utility model provides is provided with limit and turns round device between driving axle housing and the driven axle sleeve, not only rational in infrastructure, braking moment is big, and the big I of the pretightening force of spring is by bolt A adjustment, thereby sets the rated torque of this coupling.When the moment of torsion of drum-shaped tooth type friction coupling transmission is no more than the rated torque of setting, unit normal run; When the moment of torsion of drum-shaped tooth type friction coupling transmission surpasses the rated torque that sets; Produce sliding friction between outer gear piece, friction plate and the inner blade thereby slide relative takes place; This moment, driven shaft stopped operating automatically; Avoid device to be damaged because of overload, thus the Security when guaranteeing to overload.And when institute's transfer of torque is decreased to less than rated torque again, produce static friction between outer gear piece and the inner blade, and make relative movement disappear, device recovers proper functioning.
