Abstract
The invention discloses a flexible chain wheel. The flexible chain wheel comprises a chain wheel body and a wheel hub. The peripheral wall of the chain wheel body is provided with chain wheel teeth, and center of the chain wheel body is provided with a central through hole. The central through hole is internally provided with an involute inner spline. The peripheral wall of the wheel hub is provided with an involute outer spline matched with the involute inner spline. A fit clearance is formed between the involute inner spline and the involute outer spline and is filled with a flexible elastic body used for integrally connecting the chain wheel body with the wheel hub. The flexible chain wheel is arranged to be the chain wheel body and the wheel hub in a split mode; the flexible elastic body is arranged in the position, between the chain wheel body and the wheel hub, of the interior of the fit clearance; and when the chain wheel is engaged with a chain and when clamping stagnation exists between the chain wheel and the chain, through deformation of the flexible elastic body, clamping stagnation can be effectively relieved, and noise is accordingly reduced.
Description
Technical field
The present invention relates to a kind of sprocket wheel, is specifically a kind of flexible 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 flexible sprocket wheel, can mitigate chaindriven bite phenomenon, and reduce noise.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
A kind of flexible sprocket wheel, including sprocket body and wheel hub, the periphery wall of the sprocket body is provided with sprocket, 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.
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.
The beneficial effects of the present invention is：
The flexible 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.
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 flexibility sprocket wheel embodiment of the invention.
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 flexibility sprocket wheel embodiment of the invention.The flexible sprocket wheel of the present embodiment, including sprocket body 1 and wheel hub 2, the periphery wall of sprocket body 1 is provided with sprocket 3, 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 the involute inner spline 4 and involute outer spline 5 of the present embodiment is provided with the flexible elastomer 6 for sprocket body 1 and wheel hub 2 are connected as one.The width of fit clearance is 0.5-2mm, and flexible elastomer 6 made using polymer rubber alloy or soft metal coating.The width of the fit clearance of the present embodiment is 1mm, and flexible elastomer 6 made using polymer rubber alloy.
The flexible 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.
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.
