Description
Technical field
This utility model relates to a kind of sprocket wheel, and concrete is a kind of monoblock type low noise flexible filtering sprocket wheel.
Background technology
Chain conveyer is a kind of kind of drive that the motion and power with the drive sprocket of special tooth profile 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 is accurate, reliable operation, and efficiency is 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, acts on the pressure on axle little；Can at high temperature, humidity, many dirt, have in the adverse circumstances such as pollution and work.Chaindriven shortcoming mainly has: be simply possible to use in the transmission between two-parallel axis；Cost is high, easy to wear, easily extends, and transmission stability is poor, can produce additional dynamic load, vibration, impact and noise, be not preferably used in transmission reverse rapidly during operating.
Wherein, sprocket wheel axial plane profile of tooth both sides are arc-shaped, in order to chain link enters and exits 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 generally should 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 lost efficacy because of abrasion, and replaceable gear ring.Although existing sprocket wheel disclosure satisfy that instructions for use to a certain extent, but is in that when chain engages, still inevitably there is the phenomenons such as bite, cause that Chain conveyer exists the problems such as bigger noise, and chain easily comes off.
Summary of the invention
In view of this, the purpose of this utility model is in that to provide a kind of monoblock type low noise flexible filtering sprocket wheel, can not only alleviate chaindriven bite phenomenon, reduce noise, and structural strength is higher.
For reaching above-mentioned purpose, this utility model provides following technical scheme:
A kind of monoblock type low noise flexible filtering sprocket wheel, including sprocket body and wheel hub, it is provided with sprocket in the middle part of the periphery wall of described sprocket body, and set is equiped with and lays respectively at described sprocket both sides the packing ring for contact with the carrier bar of chain in described sprocket body, described packing ring employing abrasive rubber is made；The center of described sprocket body is provided with central through hole, is provided with rectangle internal spline in described central through hole, and the periphery wall of described wheel hub is provided with the rectangle external splines coordinated with described rectangle internal spline；It is provided with fit clearance between described rectangle internal spline and described rectangle external splines, in described fit clearance, fills the flexible elastomer being provided with for described sprocket body and described wheel hub being connected as one；The both sides of described sprocket body further respectively have the securing cover plate for preventing described wheel hub from moving in the axial direction.
Further, described flexible elastomer adopts polymer rubber alloy or soft metal coating to make.
Further, the width of described fit clearance is 0.5-2mm.
Further, on described securing cover plate, annular is laid with connection through hole, and described sprocket body is provided with screwed hole with the described through hole one_to_one corresponding that is connected.
Further, described screwed hole is correspondingly arranged with the tooth top of described rectangle internal spline.
Further, the periphery wall of described packing ring is provided with radially outer arc convex with the teeth groove one_to_one corresponding between adjacent two described sprockets.
The beneficial effects of the utility model are in that:
Monoblock type low noise flexible filtering sprocket wheel of the present utility model, sprocket body and wheel hub it is set to by split, and in the fit clearance between sprocket body and wheel hub, flexible elastomer is set, when sprocket wheel engages with chain, when there is bite with chain in sprocket wheel, by the deformation of flexible elastomer, can effectively alleviate bite, and correspondingly reduce noise；On the other hand, by arranging the packing ring adopting abrasive rubber to make, being in that when chain engages, the carrier bar of chain directly contacts cooperation with abrasive rubber, it is possible to is prevented effectively from rigid collision, reduces noise further；It is fixedly installed securing cover plate by the two ends in sprocket body, it is possible to effectively prevent wheel hub from moving in the axial direction, namely can improve structural strength.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, this utility model provides drawings described below to illustrate:
Fig. 1 is the structural representation of this utility model monoblock type low noise flexible filtering sprocket wheel embodiment；
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can be better understood from this utility model and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As it is shown in figure 1, be the structural representation of this utility model monoblock type low noise flexible filtering sprocket wheel embodiment.The monoblock type low noise flexible filtering sprocket wheel of the present embodiment, including sprocket body 1 and wheel hub 2, sprocket 3 it is provided with in the middle part of the periphery wall of sprocket body 1, and set is equiped with and lays respectively at sprocket 3 both sides the packing ring 10 for contacting with the carrier bar of chain in sprocket body 1, packing ring 10 adopts abrasive rubber to make, the periphery wall of the packing ring 10 of the present embodiment is provided with radially outer arc convex 12 with teeth groove 11 one_to_one corresponding between adjacent two sprockets 3, it is possible to be effectively increased the service life of packing ring 10.
