Abstract
The invention discloses an integral type flexible sprocket. The integral type flexible sprocket comprises a sprocket body and a hub. Sprocket teeth are arranged in the middle of the peripheral wall of the sprocket body. A central through hole is formed in the center of the sprocket body. Involute internal splines are arranged in the central through hole. The peripheral wall of the hub is provided with involute external splines matched with the involute internal splines. A fit clearance is formed between the involute internal splines and the involute external splines and filled with a flexible elastic body used for connecting the sprocket body and the hub into a whole. The two sides of the sprocket body are also provided with fixing cover plates correspondingly, and the fixing cover plates are used for preventing the hub from moving axially. The integral type flexible sprocket can reduce the jamming phenomenon of chain transmission and lower noise, and is higher in structural strength.
Description
Technical field
The present invention relates to a kind of sprocket wheel, is specifically a kind of monoblock type flexibility sprocket wheel.
Background technology
Chain conveyer is a kind of kind of drive that the motion of the drive sprocket with special tooth profile and power are delivered to the driven sprocket with special tooth profile by chain.Chain conveyer has many advantages, compared with V belt translation, nonelastic slip and skidding, average ratios accurately, reliable operation, efficiency high；Transmission power is big, and overload capacity is strong, and the transmission size under identical operating mode is little；Required tensile force is little, and the pressure acted on axle is little；Can in high temperature, humidity, many dirt, have pollution etc. to work in adverse circumstances.Chaindriven shortcoming mainly has：The transmission being simply possible to use between two-parallel axis；High cost, it is easy to wear, easily extend, transmission stability is poor, can produce additional dynamic load, vibration, impact and noise, be not preferably used in rapidly reverse transmission during operating.
Wherein, sprocket wheel axial plane profile of tooth both sides are in arc-shaped, enter in order to chain link and exit engagement.Sprocket should have enough contact strengths and wearability, therefore how thermally treated the flank of tooth is.The engagement number of times of minor sprocket is more than big sprocket wheel, and suffered impulsive force is also big, therefore material therefor should typically be better than big sprocket wheel.Small-diameter sprocket can be made into solid formula；The sprocket wheel of intermediate diameters can be made into orifice-plate type；The sprocket wheel being relatively large in diameter may be designed to combination type, if the gear teeth fail because of abrasion, replaceable gear ring.Although existing sprocket wheel disclosure satisfy that use requirement to a certain extent, when being that chain is engaged, still inevitably there is the phenomenons such as bite, cause Chain conveyer there are problems that larger, and chain easily comes off.
The content of the invention
In view of this, it is an object of the invention to provide a kind of monoblock type flexibility sprocket wheel, can not only mitigate chaindriven bite phenomenon, reduce noise, and structural strength is higher.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
A kind of monoblock type flexibility sprocket wheel, including sprocket body and wheel hub, sprocket is provided with the middle part of the periphery wall of the sprocket body, and the center of the sprocket body is provided with central through hole, involute inner spline is provided with the central through hole, and the periphery wall of the wheel hub is provided with the involute outer spline coordinated with the involute inner spline；Filling in fit clearance, the fit clearance is provided between the involute inner spline and the involute outer spline is provided with the flexible elastomer for the sprocket body and the wheel hub are connected as one；The both sides of the sprocket body further respectively have the securing cover plate for preventing the wheel hub from moving in the axial direction.
Further, the flexible elastomer is made using polymer rubber alloy or soft metal coating.
Further, the width of the fit clearance is 0.5-2mm.
Further, on the securing cover plate, annular is laid with connection through hole, corresponds with the connection through hole and be provided with screwed hole in the sprocket body.
The beneficial effects of the present invention is：
The monoblock type flexibility sprocket wheel of the present invention, sprocket body and wheel hub are set to by split, and flexible elastomer is set in the fit clearance between sprocket body and wheel hub, when sprocket wheel is engaged with chain, when there is bite with chain in sprocket wheel, by the deformation of flexible elastomer, can effectively mitigate bite, and correspondingly reduce noise；Securing cover plate is fixedly installed by the two ends in sprocket body, can effectively prevent wheel hub from moving in the axial direction, i.e., can improve structural strength.
Description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and illustrates：
Fig. 1 is the structural representation of monoblock type flexibility sprocket wheel embodiment of the present invention；
Left views of the Fig. 2 for Fig. 1.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in figure 1, for the structural representation of monoblock type of the present invention flexibility sprocket wheel embodiment.The monoblock type flexibility sprocket wheel of the present embodiment, including sprocket body 1 and wheel hub 2, sprocket 3 is provided with the middle part of the periphery wall of sprocket body 1, and the center of sprocket body 1 is provided with central through hole, involute inner spline 4 is provided with central through hole, and the periphery wall of wheel hub 2 is provided with the involute outer spline 5 coordinated with involute inner spline 4.Filling in fit clearance, fit clearance is provided between involute inner spline 4 and involute outer spline 5 is provided with the flexible elastomer 6 for sprocket body 1 and wheel hub 2 are connected as one；The both sides of sprocket body 1 further respectively have the securing cover plate 7 for preventing wheel hub 2 from moving in the axial direction.
Further, flexible elastomer 6 is made using polymer rubber alloy or soft metal coating, and the width of fit clearance is 0.5-2mm, and the flexible elastomer 6 of the present embodiment is made using polymer rubber alloy, and the width of fit clearance is 1mm.
Further, on securing cover plate 7 annular be laid with connection through hole 8, in sprocket body 1 be connected through hole 8 one-to-one corresponding be provided with screwed hole 9.
The monoblock type flexibility sprocket wheel of the present embodiment, sprocket body and wheel hub are set to by split, and flexible elastomer is set in the fit clearance between sprocket body and wheel hub, when sprocket wheel is engaged with chain, when there is bite with chain in sprocket wheel, by the deformation of flexible elastomer, can effectively mitigate bite, and correspondingly reduce noise；Securing cover plate is fixedly installed by the two ends in sprocket body, can effectively prevent wheel hub from moving in the axial direction, i.e., can improve structural strength.
Embodiment described above is only the preferred embodiment lifted for absolutely proving the present invention, protection scope of the present invention not limited to this.Equivalent substitute or conversion that those skilled in the art are made on the basis of the present invention, within protection scope of the present invention.Protection scope of the present invention is defined by claims.
