Technical Field
The utility model relates to a gear especially relates to a composite gear of automobile engine.
Background
The combination gear of an automobile engine is one of the more important accessories in an automobile transmission device. Automobile engine's composite gear generally all is gear wheel and pinion combination and forms, has gear wheel and pinion integrated into one piece structure on the market, also has the split type grafting package assembly of gear wheel and pinion, and the integrated into one piece structure is in the use, if the teeth of a cogwheel wearing and tearing back need wholly change, and the replacement cost is high, and split type grafting package assembly bears the ability greatly reduced of moment, and structural strength is poor, and grafting department takes place easily to damage, and current composite gear is lubricated unsatisfactory in effect moreover.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the combined gear of the automobile engine has a good using effect.
In order to solve the technical problem, the utility model discloses a technical scheme is: a composite gear for an automotive engine, comprising: the gear comprises a gear body, a large gear ring and a small gear ring, wherein the gear body comprises a large gear body part and a small gear body part which are integrally formed, a plurality of first splines are uniformly arranged on the outer side of the main body part of the big gear wheel, a plurality of first spline grooves matched with the first splines are uniformly arranged on the inner side of the big gear ring, the first splines are connected with the first spline grooves in an interference fit manner, a plurality of big gear teeth are uniformly arranged on the outer side of the big gear ring, a plurality of second splines are uniformly arranged on the outer side of the small gear body part, a plurality of second spline grooves which are matched with the second splines are uniformly arranged on the inner side of the small gear ring, the second splines are in interference fit with the second spline grooves, and a plurality of small gear teeth are uniformly arranged on the outer side of the small gear ring, and shaft holes which are communicated with each other are arranged in the middle parts of the large gear body part and the small gear body part in a penetrating manner.
In order to better solve the technical problem, the utility model discloses a further technical scheme is: a plurality of oil storage holes uniformly penetrate through the large gear body part along the axial direction, and a plug is arranged at one end, far away from the small gear body part, of each oil storage hole.
The utility model has the advantages that: the utility model provides an automobile engine's composite gear, novel structure, gear body's big gear portion and pinion portion adopt the integrated into one piece structure, structural strength is good, not fragile, big ring gear and pinion ring adopt interference fit's mode to connect respectively on gear body, can change alone the little teeth of a cogwheel on big ring gear and the pinion ring on the pinion ring gear, the replacement cost is low, radially set up a plurality of oil storage holes in big gear portion and can store partial lubricating oil, lubricating oil slowly oozes slowly from the gap between big gear portion and the pinion ring gear and can carry out long-time effective lubrication to gear end face and big and small teeth of a cogwheel, excellent in use effect.
