Abstract
The utility model discloses a flexible sprocket, including sprocket body and wheel hub, be equipped with the sprocket on the periphery wall of sprocket body, just the center of sprocket body is equipped with the central through hole, be equipped with the internal spline that gradually bursts at the seams in the central through hole, be equipped with on wheel hub's the periphery wall with internal spline's the external splines that gradually bursts at the seams gradually bursts at the seams, gradually burst at the seams the internal spline with it is equipped with the fit clearance gradually to burst at the seams between the external splines, pack in the fit clearance be equipped with be used for with the sprocket body with wheel hub connects flexible elastomer as an organic whole. The utility model discloses a flexible sprocket sets up to sprocket body and wheel hub through the components of a whole that can function independently to flexible elastomer is set up in the fit clearance between sprocket body and wheel hub, when the meshing of sprocket and chain, when there are the bite in sprocket and chain, through flexible elastomer 's deformation, the bite can be effectively alleviateed, and noise reduction correspondingly.
Description
Technical field
This utility model relates to a kind of sprocket wheel, and concrete is a kind of flexible 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 flexible sprocket wheel, it is possible to alleviates chaindriven bite phenomenon, and reduces noise.
For reaching above-mentioned purpose, this utility model provides following technical scheme:
A kind of flexible sprocket wheel, including sprocket body and wheel hub, the periphery wall of described sprocket body is provided with sprocket, and the center of described sprocket body is provided with central through hole, being provided with involute inner spline in described central through hole, the periphery wall of described wheel hub is provided with the involute outer spline coordinated with described involute inner spline；It is provided with fit clearance between described involute inner spline and described involute outer spline, in described fit clearance, fills the flexible elastomer being provided with for described sprocket body and described wheel hub being connected as one.
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.
The beneficial effects of the utility model are in that:
Flexible 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.
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 flexibility sprocket wheel embodiment.
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 flexibility sprocket wheel embodiment.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, being provided with involute inner spline 4 in central through hole, the periphery wall of wheel hub 2 is provided with the involute outer spline 5 coordinated with involute inner spline 4.It is provided with fit clearance between involute inner spline 4 and the involute outer spline 5 of the present embodiment, in fit clearance, fills the flexible elastomer 6 being provided with for sprocket body 1 and wheel hub 2 being connected as one.The width of fit clearance is 0.5-2mm, and flexible elastomer 6 adopts polymer rubber alloy or soft metal coating to make.The width of the fit clearance of the present embodiment is 1mm, and flexible elastomer 6 adopts polymer rubber alloy to make.
The flexible sprocket wheel of the present embodiment, 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.
Embodiment described above is only the preferred embodiment lifted for absolutely proving this utility model, and protection domain of the present utility model is not limited to this.Equivalent replacement that those skilled in the art make on this utility model basis or conversion, all within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with claims.
