Abstract
The utility model relates to a kind of engine gear assembly, comprises master gear, the wheel disc be arranged on described master gear, the pinion that is connected with described master gear by described wheel disc; Described master gear comprises master gear body, the lightening grooves be arranged on described master gear body, the proof rubber layer be arranged in described lightening grooves, be arranged on described master gear body two ends mounting hole, be distributed on oval mounting hole on described master gear body and rectangle mounting hole successively; Described lightening grooves is positioned at the side of described master gear body; Described wheel disc is provided with fluting; Described wheel disc inwall is provided with wearing layer.The utility model, by being arranged on proof rubber layer in lightening grooves and being arranged on the wearing layer of wheel disc inwall, extends service life of gear, arranges the mounting hole of plurality of specifications, easy for installation, stable transmission; Lightening grooves and stiffening rib are set, both decreased gear weight, reduce manufacture cost, in turn ensure that the strength and stiffness that gear is enough.
Description
Technical field
The utility model relates to auto parts and components field, particularly a kind of engine gear assembly.
Background technique
Motor be a kind of can other form can be converted into another kind of can machine, be normally mechanical energy chemical energy.Motor was both applicable to power generating apparatus, also can refer to the whole machine comprising power plant.
Gear assembly is the common gearing parts of engine interior.The gear assembly of available engine mounted inside vibrates comparatively large in the course of the work, and the wearing and tearing between gear can be made for a long time comparatively large, affect service life of gear, loosening appears in transmission, and then has influence on the normal work of motor.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of easy for installation, and transmission is firm, the engine gear assembly of long service life.Described technological scheme is as follows:
The utility model embodiment provides a kind of engine gear assembly, and described engine gear assembly comprises master gear, the wheel disc be arranged on described master gear, the pinion that is connected with described master gear by described wheel disc;
Described master gear comprises master gear body, the lightening grooves be arranged on described master gear body, the proof rubber layer be arranged in described lightening grooves, be arranged on described master gear body two ends mounting hole, be distributed on oval mounting hole on described master gear body and rectangle mounting hole successively; Described lightening grooves is positioned at the side of described master gear body; Described wheel disc is provided with fluting; Described wheel disc inwall is provided with wearing layer.
Described master gear also comprises the stiffening rib be distributed on described master gear body; Described lightening grooves is positioned at the both sides of described master gear body.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
By being arranged on proof rubber layer in lightening grooves and being arranged on the wearing layer of wheel disc inwall, extend service life of gear, the mounting hole of plurality of specifications is set, easy for installation, stable transmission; Lightening grooves and stiffening rib are set, both decreased gear weight, reduce manufacture cost, in turn ensure that the strength and stiffness that gear is enough.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the engine gear assembly that the utility model embodiment one provides;
Fig. 2 is the sectional view of the engine gear assembly that the utility model embodiment one provides;
Fig. 3 is the structural representation of the engine gear assembly that the utility model embodiment two provides;
Fig. 4 is the sectional view of the engine gear assembly that the utility model embodiment two provides.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment one
The utility model embodiment one provides a kind of engine gear assembly, and see Fig. 1, Fig. 2, described engine gear assembly comprises master gear 1, the wheel disc 2 be arranged on master gear 1, the pinion 3 that is connected with master gear 1 by wheel disc 2.
Particularly, master gear 1 comprise master gear body 11, the lightening grooves 12 be arranged on master gear body 11, the proof rubber layer 13 be arranged in lightening grooves 12, be arranged on master gear body 11 two ends mounting hole 14, be distributed on oval mounting hole 15 on master gear body 11 and rectangle mounting hole 16 successively; Lightening grooves 12 is positioned at the side of master gear body 11; If lightening grooves loss of weight is undue, has influence on integral rigidity and the intensity of gear, stiffening rib can be set on master gear body, significantly can improve strength and stiffness like this, and weight increase is few.
Particularly, wheel disc 2 is provided with fluting 21, wheel disc 2 inwall is provided with wearing layer 22, is used for extending service life of gear.
Embodiment two
The utility model embodiment two provides a kind of engine gear assembly, see Fig. 3, Fig. 4, with embodiment one unlike, master gear 1 also comprises the stiffening rib 17 be distributed on master gear body 11; Lightening grooves 12 is positioned at the both sides of master gear body 11.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
By being arranged on proof rubber layer in lightening grooves and being arranged on the wearing layer of wheel disc inwall, extend service life of gear, the mounting hole of plurality of specifications is set, easy for installation, stable transmission; Lightening grooves and stiffening rib are set, both decreased gear weight, reduce manufacture cost, in turn ensure that the strength and stiffness that gear is enough.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
