Abstract
This utility model embodiment discloses a kind of synchronous pulley, including wheel in metal and the plastic roller on wheel outer surface in being sheathed on described metal, the periphery of described plastic roller is provided with tooth intermeshing with Timing Belt, in described metal, the center of wheel offers axis hole, and the face that in described metal, wheel and described plastic roller be combined with each other is respectively provided with the stopper slot and projection being mutually twisted.The beneficial effects of the utility model are: a kind of synchronous pulley that this utility model provides, it has good axiality, being difficult to contraction distortion and torque resistant performance is good, guarantee good through-drive simultaneously, the face of gear of this outer surface does not haves burr and damages Timing Belt.
Description
Technical field
This utility model relates to a kind of drive, particularly a kind of synchronous pulley.
Background technology
Traditional synchronous pulley has greatly two kinds, i.e. metal belt wheel and plastic cement belt wheel, and material is single, exists all
Many problems, the synchronous pulley overall dimensions of metal material is stable, but processing cost is high, and particularly duplex synchronizes
Belt wheel is installed fixing again after needing to process two wheels, it is impossible to ensure good axiality, band wheel surface
Because the revolution mark stayed after Jia Gong, easily wear and tear Timing Belt, greatly reduces the service life of Timing Belt,
Plastic material synchronize wheel because the feature of plastic material itself, easily produce contraction distortion, external dimensions with
The diameter increase synchronous pulley becomes unstable, and plastic roller is not easy to realize good fixing with axle in addition.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of synchronous pulley, it has
Good axiality, is difficult to contraction distortion and torque resistant performance is good, guarantees good through-drive, in addition simultaneously
The face of gear on surface does not haves burr and damages Timing Belt.
In order to solve above-mentioned technical problem, this utility model embodiment provides a kind of synchronous pulley, and it improves it
Place is: the plastic roller on wheel outer surface, described plastic roller in including the interior wheel of metal and being sheathed on described metal
Periphery be provided with tooth intermeshing with Timing Belt, the center of wheel offers axis hole, described gold in described metal
It is respectively provided with, on the face that in belonging to, wheel and described plastic roller be combined with each other, the stopper slot and projection being mutually twisted.
In said structure, in described metal, wheel uses aluminum material.
Implement this utility model embodiment, have the advantages that
In this utility model embodiment, a kind of synchronous pulley that this utility model provides, it has good same
Axle degree, is difficult to contraction distortion and torque resistant performance is good, guarantees good through-drive, the tooth of this outer surface simultaneously
Wheel face does not haves burr and damages Timing Belt.
Accompanying drawing explanation
Fig. 1 is the structure partial sectional view of a synchronous pulley in this utility model embodiment.
Fig. 2 is the generalized section that in Fig. 1, synchronous pulley assembles with axle.
Fig. 3 is the structure partial sectional view of this utility model another synchronous pulley of embodiment.
Fig. 4 is the generalized section of synchronous pulley in Fig. 3.
Fig. 5 is the generalized section of this utility model another kind synchronous pulley and axle assembling.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by detailed description of the invention:
Referring to figs. 1 through shown in Fig. 5, Fig. 1, Fig. 3 and Fig. 5 respectively illustrate a few money typical Timing Belt rolling hitch
Structure, as it can be seen, this utility model discloses a kind of synchronous pulley, including taking turns 2 in metal and being sheathed on gold
Plastic roller 1 on wheel 2 outer surfaces in belonging to, the periphery of plastic roller 1 is provided with tooth 12 intermeshing with Timing Belt,
It should be understood that the center of wheel 2 offers axis hole 22 in metal, in order to axle 4 is by bearing 3 and Timing Belt
Wheel assembles mutually, additionally, in order to strengthen plastic roller and the stability of wheel 2 in metal, take turns 2 and mould in metal
The stopper slot 21 and protruding 11 being mutually twisted it is respectively provided with, of course for enhancing on the face that rubber tire 1 be combined with each other
The torque resistant performance of synchronous pulley alleviates synchronous pulley weight simultaneously, wheel 2 employing aluminum material in metal.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to this reality
With novel restriction.In technological thought category of the present utility model, various deformation and amendment can occur,
Retouching, amendment or the equivalent that all those of ordinary skill in the art are made as described above, belongs to
The scope that this utility model is protected.
Claims (2)
1. a synchronous pulley, it is characterised in that: take turns in including metal and be sheathed on wheel appearance in described metal
Plastic roller on face, the periphery of described plastic roller is provided with tooth intermeshing with Timing Belt, wheel in described metal
Center offer axis hole, the face that wheel and described plastic roller be combined with each other in described metal is respectively provided with mutually
The stopper slot of occlusion and projection.
A kind of synchronous pulley the most according to claim 1, it is characterised in that: in described metal, wheel uses
Aluminum material.
