Description
Technical field
It is specifically a kind of duplicate sprocket the present invention relates to a kind of 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, and compared with V belt translation, nonelastic slip and skidding, average ratios are accurate, reliable operation, efficiency high；Transmission power is big, and overload capacity is strong, and the transmission size under identical operating mode is small；Required tensile force is small, and the pressure acted on axle is small；Can in high temperature, humidity, many dirt, there is pollution etc. to work in adverse circumstances.Chaindriven shortcoming mainly has：It is simply possible to use in the transmission between two-parallel axis；High cost, easy to wear, easily elongation, transmission stability is poor, and additional dynamic load, vibration, impact and noise can be produced during operating, is not preferably used in rapidly reverse transmission.
Wherein, sprocket wheel axial plane tooth form both sides are in arc-shaped, enter and exit engagement in order to chain link.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 combined 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 flexible filtering duplicate sprocket, chaindriven bite phenomenon can not only be mitigated, noise is reduced, and structural strength is higher.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of monoblock type flexible filtering duplicate sprocket, including sprocket body, two sprocket wheels are provided with the periphery wall of the sprocket body side by side, 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 the side sensing sprocket body where it, and 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 the flexible elastomer filled be provided with for the wheel hub with the sprocket body to be connected as one is provided with fit clearance, the fit clearance between the wheel hub and the corresponding bellmouth；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 of polymer rubber alloy or soft metal coating.
Further, the width of the fit clearance is 0.5-2mm.
Further, two bellmouths are axisymmetricly set.
Further, annular is laid with connection through hole on the securing cover plate, is corresponded with the connection through hole in the sprocket body and is provided with screwed hole.
Further, the screwed hole is arranged between the two neighboring rectangle teeth groove.
The beneficial effects of the present invention are：
Monoblock type flexible filtering duplicate sprocket of the invention, two sections of bellmouths are set to by the central through hole in 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 and chain have bite, by the deformation of flexible elastomer, bite can effectively be mitigated, 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.
Brief 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 flexible filtering duplicate sprocket embodiment of the present invention；
