Abstract
The invention discloses a low-noise flexible filtering duplex chain wheel. The low-noise flexible filtering duplex chain wheel comprises a chain wheel body. The peripheral wall of the chain wheel body is provided with two chain wheel main bodies in parallel. The two sides of the two chain wheel main bodies are provided with gaskets which are installed on the chain wheel body in a sleeving mode and used for making contact with a chain plate of a chain correspondingly. The gaskets are made of abrasion-resistant rubber. The center of the chain wheel body is provided with central through holes which comprise the two sections of central through holes located in the two sides correspondingly. The two sections of central through holes are both conical holes, and the inner diameter of the conical holes is gradually decreased along the side where the conical holes are located in the direction pointing to the center of the chain wheel body. Rectangular tooth grooves are uniformly distributed in each conical hole in an annular mode. A wheel hub is installed in each section of conical hole in a sleeved mode. The peripheral wall of each wheel hub is provided with rectangular teeth matched with the rectangular tooth grooves, and a fit clearance is formed between each wheel hub and the corresponding conical hole. Each fit clearance is filled with a flexible elastic body used for integrally connecting the corresponding wheel hub with the chain wheel body.
Description
Technical field
The present invention relates to a kind of sprocket wheel, is specifically a kind of low noise flexible filtering duplicate sprocket.
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 low noise flexible filtering duplicate sprocket, can mitigate chaindriven bite phenomenon, and reduce noise.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
A kind of low noise flexible filtering duplicate sprocket, including sprocket body, it is provided with two sprocket wheels on the periphery wall of the sprocket body side by side, two sprocket wheels are respectively provided on two sides with the packing ring for being sleeved in the sprocket body and contacting for the carrier bar with chain, and the packing ring is made using abrasive rubber；The center of the sprocket body is provided with central through hole, the central through hole includes two sections respectively positioned at both sides, two sections of central through holes are disposed as bellmouth, and the internal diameter of the bellmouth is gradually reduced along the direction at the center of its place side sensing sprocket body, the bellmouth annular is laid with rectangle teeth groove；It is set with two sections of bellmouths and is provided with wheel hub, the periphery wall of the wheel hub is provided with the rectangular teeth with the rectangle tooth socket fit, and fit clearance between the wheel hub and the corresponding bellmouth, is provided with, the interior filling of the fit clearance is provided with the flexible elastomer for the wheel hub is connected as one with the sprocket body.
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, two bellmouths are axisymmetricly arranged.
Further, correspond with the sprocket indentations of the corresponding sprocket wheel on the periphery wall of the packing ring and be provided with radially outer arc convex.
The beneficial effects of the present invention is：
The low noise flexible filtering duplicate sprocket of the present invention, two sections of bellmouths are set to by the central through hole in the sprocket body, and in two sections of bellmouths installation wheel hub, and flexible elastomer is set between bellmouth and wheel hub, when sprocket wheel is engaged with chain, when sprocket wheel has bite with chain, by the deformation of flexible elastomer, bite can effectively be mitigated, 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.
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 low noise flexible filtering duplicate sprocket embodiment of the present invention；
