Abstract
The utility model discloses a synchronous pulley provided with a locking ring. The locking ring is arranged on the synchronous pulley, the axial line of the locking line and the axial line of the synchronous pulley are located on the same straight line, the locking ring is fixedly connected with the synchronous pulley, a radial gap is formed in the locking ring, a threaded counter bore is further formed in the side face of the locking ring, and the threaded counter bore penetrates through the gap and is perpendicular to the gap. Through the mode, the synchronous pulley can be directly connected with a ray axis, a key groove does not need to be formed in the synchronous pulley, connection is stable, sliding is not prone to occurring, and the service life of the synchronous pulley is prolonged.
Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of synchronous pulley with locking ring.
Background technique
Closed ring adhesive tape and corresponding belt wheel that synchronous belt pulley transmission is provided with equidistant tooth by an interior perimeter surface are formed.Synchronous pulley is generally made by materials such as steel, aluminum alloy, cast iron, brass, inside has circular hole, D shape hole, and the forms such as cone shape hole, surface treatment has the processing such as true qualities oxidation, blackout, zinc-plated, zinc electroplating with iridescent yellow chromate conversion coating, high frequency hardening.Timing Belt can be divided into neoprene by material and add textile rope Timing Belt, and polyurethane adds steel wire Timing Belt, by the shape of tooth, is mainly divided into stepped tooth and the large class of circle-arc tooth two, by toothed arrangement surface, can be divided into single cog Timing Belt and double cog synchronous belt again.Toothed belt transmission has velocity ratio accurately, without slippage, can obtain constant speed ratio, can precision drive, stable drive, energy shock-absorbing, noise is little, and transmission speed ratio scope is large, generally can reach 1: 10, allow linear velocity can reach 50m/s, transmission efficiency is high, generally can reach 98 ℅-99 ℅.Transmitted power is from several watts to hundreds of kilowatts.Compact structure is applicable multiaxis transmission also, and tension force is little, does not need to lubricate, pollution-free.During motion, with tooth, be meshed with the teeth groove of belt wheel and transmit motion and power, be a kind of engagement driving, thereby there are the various features of gear transmission, chain transmission and flat belt driving.Be widely used in the fields such as automobile, weaving, printing packaging equipment, needling equipment, office equipment, laser engraving equipment, tobacco, financial machine and tool, light of stage, communication food machinery, medical machinery, steel machinery, petrochemical industry, instrument and apparatus, various precision machine tools.
Existing synchronous pulley is keyway with connecting of axle, need to be on synchronous pulley and axle keystroke groove, connecting mode is unstable, easily loosening, key and keyway circular runout, axial motion, of long duration will wearing and tearing, key connects connecting generation notch effect, affects bearing capacity and the working life of workpiece.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of synchronous pulley with locking ring, can make synchronous pulley directly be connected with optical axis, need on synchronous pulley, not spline, and stable connection, is not easy to skid, and has improved the working life of synchronous pulley.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of synchronous pulley with locking ring is provided, on described synchronous pulley, be provided with a locking ring, the shaft axis of described locking ring and the shaft axis of synchronous pulley are on same straight line, between locking ring and synchronous pulley for being fixedly connected with, on described locking ring, have a seam radially, the side of locking ring also has a screw-threaded counterbore, and described screw-threaded counterbore is through seam and vertical with seam.
Preferably, described locking ring is connected with the bolt that is fixedly connected as between synchronous pulley.
Preferably, on described locking ring, also have a positioning pin hole.
The beneficial effects of the utility model are: the utility model arranges coaxial locking ring by the side at synchronous pulley, synchronous pulley can be directly connected with optical axis, need on synchronous pulley, not spline, connect more stable, be not easy to skid, improved the working life of synchronous pulley.
Accompanying drawing explanation
Fig. 1 is the plan view of prior art synchronous pulley;
Fig. 2 is the plan view of a kind of synchronous pulley one preferred embodiment with locking ring of the utility model;
Fig. 3 is the plan view of described a kind of synchronous pulley one preferred embodiment with locking ring.
In accompanying drawing, the mark of each parts is as follows: 1, synchronous pulley, 2, locking ring, 3, seam, 4, bolt, 5, positioning pin hole, 6, screw-threaded counterbore.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 2 and Fig. 3, the utility model is embodiment comprise:
A kind of synchronous pulley with locking ring, on described synchronous pulley 1, be provided with a locking ring 2, the shaft axis of the shaft axis of described locking ring 2 and synchronous pulley 1 is on same straight line, between locking ring 2 and synchronous pulley 1 for being fixedly connected with, on described locking ring 2, have a seam 3 radially, the side of locking ring 2 also has a screw-threaded counterbore 6, and described screw-threaded counterbore 6 is through seam 3 and vertical with seam 3.During installation, optical axis is stretched in axis hole, with bolt, be screwed into the screw-threaded counterbore 6 of locking ring 2 sides, be subject to the effect of bolt pretightening, the seam 3 on locking ring 2 tightens up, thereby the axis hole of optical axis and synchronous pulley 1 is combined closely, be connected and compare with key, improved the stability connecting, and be not easy wearing and tearing.
Further, described locking ring 2 is connected with the bolt that is fixedly connected as between synchronous pulley 1, and mounting or dismounting are convenient, are beneficial to maintenance.
Further, on described locking ring 2, also have a positioning pin hole 5, and on synchronous pulley 1, also have a tapped hole, the position of described tapped hole is corresponding with the position of positioning pin hole 5, bolt is screwed into positioning pin hole 5, has improved the stability that synchronous pulley 1 is connected with locking ring 2.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
