Abstract
An engine gear device belongs to the technical field of automobile and motorcycle component and comprises an engine gear body, a gear hole and at least one bearing group; wherein the gear hole is provided at the center of the engine gear body, the bearings are arranged in the gear hole and have tight fit to the inner wall of the gear hole, the bearings are longitudinally provided in the gear holeand are roller bearings. Compared to the prior art, the engine gear device has the advantages that since the engine gear is provided with bearings, the abrasion on the wall of the gear hole can be avoided, thereby prolonging service life of the engine gear device, and the engine gear device can be maintained via exchanging bearings without exchanging the whole gear device. The engine gear device has the advantages of simple exchange, reduced maintenance cost and improved product quality.
Description
Technical field
The utility model relates to a kind of engine gear device, particularly relates to a kind of engine gear device of adorning bearing, belongs to automobile, motorcycle part technical field.
Background technique
Automobile and motorcycle are the most frequently used traffic tool of people, and the engine gear device is one of most important parts in automobile and the motorcycle engine, also are a kind of easily worn parts.As shown in Figure 1, in the engine gear device of present automobile, motorcycle, bearing is not installed, when axle rotated with gear, the bore wall wore and tore easily, increased friction factor, reduction of service life; Because no bearing in the engine gear device makes very quick-wearing of bore wall, during maintenance, need to change whole gearing, make the maintain and replace difficulty big, the cost height.
The model utility content
The purpose of this utility model is the defective at above-mentioned prior art, and a kind of engine gear device is provided, and can avoid the wearing and tearing of bore wall, increases the service life.Reduce maintenance cost, it is convenient to change, and has reduced maintenance cost, has improved quality of product.
The technological scheme taked of the utility model is to achieve these goals: a kind of engine gear device, comprise engine gear main body, gear hole, engine gear main center is a gear hole, also comprises bearing, bearing is in gear hole, and bearing and gear hole inwall are drive fit; Lengthwise position in gear hole is provided with a group or more bearing.
Described bearing is vertically arranged with 2 groups at gear hole.
Described bearing is a needle bearing.
Described needle bearing is the HK101410 needle bearing.
Compared with prior art, the beneficial effects of the utility model are:
(1) owing to bearing has been installed, can avoid the wearing and tearing of bore wall, prolong the working life of engine gear device at engine gear;
(2) owing to, do not need to change whole gearing, just can finish maintenance, like this, just reduce maintenance cost, improve quality of product as long as change bearing;
(3) change conveniently, just can use at once as long as change bearing.

Accompanying drawing 1 original product master looks sectional view;
Accompanying drawing 2 the utility model masters look sectional view.
Description of reference numerals: 1 engine gear main body, 2 gear holes, 3 bearings
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
As shown in Figure 2, a kind of engine gear device comprises engine gear main body 1, gear hole 2, and engine gear main body 1 center is a gear hole 2, also comprises bearing 3, and bearing 3 is in gear hole 2, and bearing 3 is a drive fit with gear hole 2 inwalls; Lengthwise position in gear hole 2 is provided with 2 groups of bearings 3, and bearing 3 is the HK101410 needle bearing.When the HK101410 needle bearing weares and teares,, just can rework at once as long as simply it is replaced to new HK101410 needle bearing.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
