Abstract
The utility model discloses an eccentric gear mechanism, which belongs to the field of mechanical structures and comprises an eccentric gear and a main shaft, wherein the eccentric gear is arranged on the main shaft, screw holes and bumps are arranged on the eccentric gear, the combination part of the eccentric gear and the main shaft is provided with a gasket, and the middle part of the main shaft is provided with a bearing group. The gasket is arranged between the eccentric gear and the main shaft, so that the main shaft is protected from being scratched, and the eccentric gear does not easily slide; and a plurality of bearings are arranged on the main shaft, so that the mechanism can operate in a balanced way, the friction is reduced, abrasion to the mechanism is reduced, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of mechanical mechanism, is specifically related to a kind of eccentric gear mechanism.
Background technique
Common eccentric gear mechanism is arranged on eccentricity gear above main shaft, and on eccentricity gear, offer screw, and use bolt that eccentricity gear is fixed on above main shaft, pressure can cause the main shaft cut to deepen for a long time, make eccentricity gear shake, fixed effect is poor.Existing eccentric gear mechanism joint frictional force is large, easily makes mechanism and scraps because of wearing and tearing, causes shorten working life.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The model utility content
It is strong that the purpose of this utility model is to provide a kind of stable row, the eccentric gear mechanism of long service life.
For reaching above-mentioned purpose, the technological scheme that the utility model adopts is: a kind of eccentric gear mechanism is provided, comprises eccentricity gear and main shaft, eccentricity gear is arranged on main shaft.Eccentricity gear is provided with screw and projection, and and the connecting part of main shaft between be provided with pad, and the middle part of main shaft is provided with bearing pack.
Preferably, pad is arranged between the bottom and main shaft of screw.
Preferably, bearing pack comprises three bearings.
Preferably, projection is evenly distributed on the lateral ends of eccentricity gear.
In sum, the utility model advantage: be provided with pad between screw and main shaft, main shaft is protected, prevent that main shaft is scratched, make eccentricity gear be difficult for sliding; On main shaft, be provided with a plurality of bearings, make the mechanism can balanced running, friction reduces, and the wearing and tearing of mechanism are reduced, and increase working life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, eccentricity gear; 2, main shaft; 3, screw; 4, projection; 5, bearing pack.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
The present utility model a kind of eccentric gear mechanism is provided, as shown in Figure 1, comprise eccentricity gear 1 and main shaft 2, eccentricity gear 1 is arranged on main shaft 2.Eccentricity gear 1 is provided with screw 3 and projection 4, and an end of main shaft 2 gos deep into eccentricity gear 1 inside, and uses screw rod to pass screw 3 eccentricity gear 1 is fixed on main shaft 2.Between the connecting part of eccentricity gear 1 and main shaft 2, be provided with pad; The middle part of described main shaft 2 is provided with bearing pack 5.
Further, pad is arranged between the bottom and main shaft 2 of screw 3.
Further, bearing pack 5 comprises three bearings.
Further, projection 4 is evenly distributed on the lateral ends of eccentricity gear 1.This lateral ends refers to the round nose of eccentricity gear 1 near bearing pack 5.
Although by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
