Abstract
The utility model relates to a low percussion safety joint slack which belongs to the transmission connector. The utility model comprises an inner sleeve and an outer ring which are matched together, wherein spline grooves are arranged at the outer side of the inner sleeve and the inner side of the outer ring respectively. A big friction disk slice and a small friction disk slice are orderly sheathed between the inner sleeve and the outer ring at intervals, and a spline is arranged at the external periphery of the big friction disk slice, and corresponds to the spline groove on the outer ring. A spline is arranged on the internal periphery of the small friction disk slice, and corresponds to the spline groove on the inner sleeve; a pressing nut is arranged on the outer end of the inner sleeve. The utility model which has simple and reasonable structure is combined together by the pressing between the friction disk slices, and the joint slack has buffering capability and can be adjusted with favorable protection feature; the utility model has small hardness impact especially when the utility model is powered on or powered off, and can effectively prolong the service life of the application apparatus, such as a decelerator, an electric motor, etc. The utility model has low positioning requirement, flexible and convenient installation, high reliability and long service life, and is especially applied to the radiotherapy decelerator.
Description
Technical field
The utility model relates to a kind of improved coupling, belongs to transmission connection piece.
Background technique
Coupling is the transmission connection piece of often using; in the practice; most coupling all is directly to be rigidly connected; impact phenomenon is serious, steady inadequately when starting and shut down, and directly influences the working life of equipment; many times should adjust; as the accelerator that uses in the radiotherapy, drive the pivoted arm rotation of accelerator, need use coupling.
Summary of the invention
The purpose of this utility model is to provide a kind of low impact safety coupling, has shock-absorbing capacity, plays a protective role.
Low impact safety coupling described in the utility model, interior cover and outer ring that matched together is arranged, the outside of interior cover and the inboard of outer ring are respectively equipped with spline, in between cover and the outer ring successively at interval closed assembly big or small friction disc is arranged, the outer periphery of big friction disc is provided with spline, and corresponding with the spline on the outer ring, the inner periphery of friction disc is provided with spline, corresponding with the interior spline that puts, the outer end of interior cover is provided with gland nut.
The gland nut precession is compressed, and each friction disc is extruded and is pressed together, and the outer ring is connected with interior cover, and formation is flexible coupling.Suitably regulate the degree that compresses of gland nut, can when running into certain resistance, make between the friction disc and skid, play buffer protection function.During use, interior cover is connected the diaxon that needs connect respectively with the outer ring.
Friction disc can have 2-10, friction disc the more, frictional force is bigger.The friction disc of outer end can a side be a rubbing surface, and middle friction disc can be that both sides are rubbing surface.
Friction disc preferably is bonded on the metal frame by the copper wire asbestos and makes, and friction effect is good.
At the two butterfly springs of the inboard dress of gland nut, be beneficial to the impacting force of regulating gland nut, gland nut can use double nut.
The utility model is simple and reasonable; link together by compressing between friction disc, shock-absorbing capacity is arranged, can regulate; has the excellent protection characteristic; especially rigid impact is little when starting and shut down, and can effectively prolong the working life that retarder and motor etc. use equipment, and positioning requirements is low; convenient and flexible installation; the reliability height, long service life, suitable especially being applied on the radiotherapy accelerator.
