Description
Technical field
The utility model belongs to motor car engine manufacturing technology field, specially refers to a kind of multifunctional integral sprocket wheel that is used to be installed on the bent axle.
Background technique
In order to reduce vibration and to make moment of torsion be able to better transmission, all be equipped with trunnion shaft on the motor, to increase the travelling comfort of car load.Trunnion shaft generally is by being assemblied in gear on the bent axle through chain transmission, and oil pump, camshaft also are to cog through chain transmission by bent axle.Above-mentioned three gears that are assemblied in crankshaft front end all are the parts that separates separately, and are to process separately in process of production, will process locating stud on each gear and position.In course of working, all can inevitably there be certain axial error in each gear, like this when three gears all are assembled to crankshaft front end, a bigger stack tolerance can appear in the axial direction, make the sprocket wheel that is assemblied on the bent axle and the sprocket wheel that will drive (such as camshaft timing gear and crankshaft timing gear) not at grade, thereby do not make chain also not at grade, the stressed meeting of chain Off center face, the eccentric wear phenomenon appears, chain, the sprocket wheel and the guide rail lost of life, the long-term operation meeting makes timing deviation occur, and phase deviation will directly affect machine performance and reliability.
Summary of the invention
The purpose of this utility model provides a kind of multifunctional integral sprocket wheel, reducing assembly error, thereby reduces the eccentric wear phenomenon between each sprocket wheel and its actuation gear, the travelling comfort and the working life of raising car load.
Multifunctional integral sprocket wheel of the present utility model comprises that central authorities have the body of axis hole, one end of body is provided with positioning key, described body axially be provided with trunnion shaft sprocket wheel, crankshaft timing sprocket and oil pump sprocket wheel, key is that described trunnion shaft sprocket wheel, crankshaft timing sprocket, oil pump sprocket wheel and body are made into integration.
During assembling positioning key is aimed at match with the locating slot of bent axle, and tight a bolt by axis hole and to get final product convenient and reliable assembly.Positioning key can prevent effectively that sprocket wheel from when being subjected to high pulling torque, skidding around bent axle when guaranteeing to aim at timing, guarantee the normal operation of motor.With the combining and being made into integration of three sprocket wheel compactnesses with body, the complete machine transverse dimension is reduced, and reduced the axial overlay error of a plurality of sprocket wheels, and axial float is easy to control, therefore increased the stability of sprocket wheel, improved car load NVH performance.
Further, have at least the number of teeth of two adjacent sprocket wheels identical in described trunnion shaft sprocket wheel, crankshaft timing sprocket, the oil pump sprocket wheel with pitch.The number of teeth that can at first process two sprocket wheels identical with pitch are reprocessed remaining sprocket wheel like this, can reduce difficulty of processing, and manufacturing procedure is become simply, are convenient to processing, reduce cost.
Further, the two ends of described body all protrude in the plane at its sprocket wheel place, end, can be expressed to the chain on the sprocket wheel of end in the time of not only can avoiding bolt to tighten, and can also prevent that chain and the cylinder body side on the sprocket wheel of end from rubbing.
Further, in described trunnion shaft sprocket wheel, crankshaft timing sprocket, the oil pump sprocket wheel between the adjacent sprocket wheel at a distance of predetermined interval, bump and rub to avoid the chain between the adjacent sprocket wheel.
Multifunctional integral sprocket wheel of the present utility model combining and being made into integration with body three sprocket wheel compactnesses, processing and assembling is convenient, easily locatees, and axially overlay error is little, can effectively reduce the eccentric wear phenomenon between each sprocket wheel and its actuation gear, improve the travelling comfort and the working life of car load.

Embodiment
Describe the utility model in detail below in conjunction with specific embodiments and the drawings.
Embodiment 1:
As shown in Figure 1, 2, the multifunctional integral sprocket wheel of present embodiment comprises body 1, is furnished with trunnion shaft sprocket wheel 2, crankshaft timing sprocket 3 and oil pump sprocket wheel 4 on the body 1 vertically successively.Be furnished with the gear teeth respectively on the wheel disc of trunnion shaft sprocket wheel 2, crankshaft timing sprocket 3 and oil pump sprocket wheel 4, be used for and the chain match, to distinguish driven equilibrium axle, camshaft, oil pump by chain.Be first axle journal 5 between trunnion shaft sprocket wheel 2 and the crankshaft timing sprocket 3, the chain on chain in the time of can avoiding turning round on the trunnion shaft sprocket wheel 2 and the crankshaft timing sprocket 3 bumps and rubs; 4 on crankshaft timing sprocket 3 and oil pump sprocket wheel are second axle journals 6, and the chain on chain when preventing to turn round equally on the crankshaft timing sprocket 3 and the oil pump sprocket wheel 4 bumps and rubs; The outside of oil pump sprocket wheel 4 is the 3rd axle journals 7 that protrude in plane, oil pump sprocket wheel 4 place, is expressed to the chain on the oil pump sprocket wheel 4 in the time of can effectively avoiding bolt to tighten, and influences the normal operation of motor.
Be furnished with the boss 8 that protrudes in plane, trunnion shaft sprocket wheel 2 place in the outside of trunnion shaft sprocket wheel 2, be used for preventing that chain and cylinder body side on the trunnion shaft sprocket wheel 2 from rubbing, be furnished with positioning key 9 on the boss 8, be used for cooperating the location with the crankshaft front end positioning hole.The central authorities of body 1 are provided with axis hole 10, can be tightened on the bent axle by bolt.
Trunnion shaft sprocket wheel 2, crankshaft timing sprocket 3 and oil pump sprocket wheel 4 all adopt heat treatment process, have increased hardness, reduce wear.
In the present embodiment, for the ease of the relation of the velocity ratio between layout, processing and gear, crankshaft timing sprocket 2 is arranged between trunnion shaft sprocket wheel 2 and the oil pump sprocket wheel 4, and wherein crankshaft timing sprocket 3 is identical with the number of teeth and the pitch of oil pump sprocket wheel 4.Adding man-hour, crankshaft timing sprocket 3 can be processed simultaneously with the gear teeth of oil pump sprocket wheel 4, and then processes first axle journal 5, second axle journal 6 and the 3rd axle journal 7, processes trunnion shaft sprocket wheel 2 at last, to significantly reduce difficulty of processing and time.While first axle journal 5, after the length of second axle journal 6 and the 3rd axle journal 7 (being the interval between adjacent two sprocket wheels) will guarantee the fit on sprocket wheel, gap between adjacent chain is about 1.5mm, spacing between two chains too conference makes design not compact, be difficult for arranging that the too little meeting of spacing makes between chain and rubs.
