Description
Technical field
The present invention relates to a kind of sprocket wheel, is specifically a kind of monoblock type low noise 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 low noise 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 low noise flexibility sprocket wheel, including sprocket body and wheel hub, it is provided with sprocket, and the sprocket body to cover is equiped with the middle part of the periphery wall of the sprocket body and be located at respectively the sprocket both sides the packing ring contacted for the carrier bar with chain, the packing ring is made using abrasive rubber；The center of the sprocket body is provided with central through hole, is provided with involute inner spline in 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.
Further, the teeth groove on the periphery wall of the packing ring and between the two neighboring sprocket is corresponded and is provided with radially outer arc convex.
The beneficial effects of the present invention is：
The monoblock type low noise 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；On the other hand, by arranging using packing ring made by abrasive rubber, when being that chain is engaged, the carrier bar of chain is directly engaged with abrasive rubber, can be prevented effectively from rigid collision, further reduces 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 low noise 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 low noise of the present invention flexibility sprocket wheel embodiment.The monoblock type low noise 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 set is equiped with sprocket body 1, packing ring 10 is made using abrasive rubber, teeth groove 11 on the periphery wall of the packing ring 10 of the present embodiment and between two neighboring sprocket 3 is corresponded and is provided with radially outer arc convex 12, can be effectively increased the service life of packing ring 10.
The center of sprocket body 1 is provided with central through hole, is provided with involute inner spline 4 in 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.
