Be installed in the anti-dust seal on the ring in the described metal;
Be installed on the described axle sleeve and with the contacted speed counter of described anti-dust seal.
Preferably, in above-mentioned speed counting device, ring designs for integral type in described anti-dust seal and the described metal.
Preferably, in above-mentioned speed counting device, ring is gone up with described front rim touching position and is provided with rubber layer in the described metal.
Preferably, in above-mentioned speed counting device, the quantity of described metal flange is two.
Preferably, in above-mentioned speed counting device, on described metal flange is symmetricly set on and encircles in the described metal.
Preferably, in above-mentioned speed counting device, the lip of described speed counter and described anti-dust seal is an interference fit.
Preferably, in above-mentioned speed counting device, described transmission worm gear is a plastics transmission worm gear.
From technique scheme as can be seen, among the utility model embodiment in the speed counting device anti-dust seal by in the metal ring be installed on the axle sleeve, ring plays anti-loosening effect in the metal, and ring is that the such dust of interference fit just can't enter from this contact surface with front rim in the metal.Therefore when work, can reduce the wearing and tearing of anti-dust seal and front rim, can extend, therefore will improve the dustproof effect of speed counting device, and then prolong the service life of front rim 1 so wearing and tearing reduce the anti-dust seal period of service.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The detail drawing of the speed counting device that Fig. 1 provides for the utility model embodiment;
The assembly drowing of the speed counting device that Fig. 2 provides for the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of speed counting device, to improve the dustproof effect of speed counter.
As depicted in figs. 1 and 2, this speed counting device is installed on the front rim 1 of motor bike, by the speed of measuring the motorcycle front-wheel rim and then the moving velocity that obtains motor bike, is provided with anti-dust seal 3 between speed counter and motorcycle front-wheel rim.This anti-dust seal 3 is to be installed on the axle sleeve by ring 2 in the metal, can prolong the service life of anti-dust seal 3.
This concrete speed counting device comprises: ring 2, anti-dust seal 3, speed counter 5 and transmission worm gear 7 in front rim 1, axle sleeve 6, the metal, and wherein, described axle sleeve 6 is sleeved on the main shaft of motorcycle front-wheel rim 1; Described transmission worm gear 7 is contained on the axle sleeve 6; Ring 2 is sleeved on the axle sleeve 6 in the metal, and with the fit system of front rim 1 be interference fit, adopt interference fit can prevent effectively that ring 2 is loosening in the metal, ring 2 is provided with metal flange 21 near an end of the bearing 1 that front rim 1 is installed in the metal, metal flange 21 cooperates with the boss of transmission worm gear 7, and the rotation mileage of front rim 1 is passed.Ring 2 is an interference fit with the fit system of front rim 1 in the metal, and then stops dust to enter in the bearing 4 of front rim by the slit between ring 2 and the front rim 1 in the metal effectively; Anti-dust seal 3 is sleeved in the metal and contacts on the ring 2 and with speed counter 5.
For ring in anti-dust seal 3 easy for installation and the metal is not got rid of split-type design certainly 2 for integral type designs, can change wherein parts when the component wear separately for split-type design.For integral type design, its dust reduction capability is more reliable, can be because of not the coming off of anti-dust seal 3, enter bearing 4 and cause in the slit of dust ring 2 in anti-dust seal 3 and the metal.Transmission worm gear 7 is a metal transmission worm gear, can also be plastics transmission worm gear, adopts plastics transmission worm gear can alleviate the weight and the cost of speed counter, reduces the front-wheel rolling resistance, improves vehicle performance.
For dustproof better, the joining place of ring 2 is provided with the gradient in anti-dust seal 3 and metal, even therefore dust enters also and can accumulate at the orlop of the gradient from the slit of anti-dust seal 3 and front rim, and can directly not enter bearing 4 inside.
The metal flange 21 on the ring 2 makes the interior ring of bearing 4 and metal have certain distance in the metal in addition, therefore, can have certain spatial cache even dust enters also.
In order to encircle 2 in the fixing metal better, the quantity of metal flange 21 is two, and there are certain distance in two metal flange 21, and it is fixing more firm for ring 2 in the metal of this spline structure.Preferably, metal flange 21 is symmetricly set in the described metal on the ring 2, is symmetrical arranged to guarantee fixing more firm of ring in the metal 2, and it is more even to guarantee that ring 2 in the metal acts on the power of transmission worm gear 7.
In order to guarantee the leakproofness of speed counter 5 and anti-dust seal 3 better, the lip 31 and the fit system between the speed counter 5 of anti-dust seal 3 are interference fit.
From technique scheme as can be seen, among the utility model embodiment in the speed counting device anti-dust seal 32 be installed on the axle sleeve 6 by ring in the metal, ring 2 plays anti-loosening effect in the metal, and ring 2 and front rim 1 just can't enter from this contact surface for the such dust of interference fit in the metal.Therefore when work, can reduce the wearing and tearing of anti-dust seal and front rim 1, can extend, therefore will improve the dustproof effect of speed counting device, and then prolong the service life of front rim 1 so wearing and tearing reduce the anti-dust seal period of service.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
