Abstract

The utility model discloses an automobile engine exhaust cam shaft in right time belt pulley, including a plurality of spoke of the teeth of a cogwheel with the connection teeth of a cogwheel, the shape and the quality of spoke all different, produce out of balance at the high -speed in -process that rotates of belt pulley, be used for offsetting and rotate the disequilibrium that produces with belt pulley matched with camshaft. The utility model discloses an automobile engine exhaust cam shaft in right time belt pulley, through finite element analysis to the part analog computation, find the part shape that accords with the part function most and be convenient for make, the density distribution of each part of close check part when taking shape, make the part accord with the imbalance degree requirement, can be used for offsetting the disequilibrium of camshaft, thereby reduce the whole vibrations of engine, it is more steady to make its operation, the vibrations that produce when high -speed operation the that the disequilibrium that can effectively solve the camshaft leads to, it is littleer to compare the engine vibrations of not having this design, it is more steady to operate, and has good practicality.

Description

A kind of car engine timing exhaust cam shaft pulley
Technical field
This utility model relates to powder metallurgical technology, is specifically related to a kind of car engine timing exhaust cam shaft pulley.
Background technology
Car engine timing exhaust cam shaft pulley, use within the engine, be arranged on timing exhaust cam shaft, transmit power by belt, drive cam axle thus controlling the folding of exhaust valve, owing to camshaft is that eccentric shaft is asymmetric, producing vibrations when running up, existing belt pulley is homogeneous texture, vibrations can not be weakened, offset the imbalance of camshaft, thus causing the overall vibrations of electromotor, galloping.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of car engine timing exhaust cam shaft pulley, the vibrations produced when running up that the disequilibrium to effectively solving camshaft causes, operates more steady.
Technical scheme: in order to realize foregoing invention purpose, the scheme that this utility model adopts is:
A kind of car engine timing exhaust cam shaft pulley, including the gear teeth and several spokes connecting the gear teeth, the shape of described spoke and quality are all different, produce imbalance in belt pulley high-speed rotation process, are used for offsetting the imbalance that the cam axle matched with belt pulley produces.
Having 3 at described spoke, a spoke is provided with abnormity keyway wherein, and the angle of the centrage of described abnormity keyway and another spoke is 115 ° ± 5 °.
The powder metallurgy of described camshaft pulley consists of: Fe: surplus;Cu:1.5 ~ 3.9%;C:0.3 ~ 0.6%;Impurity is less than 2%.
The density of described camshaft pulley is at 6.6g/cm3Above, perpendicularity: within ⊥ 0.025mm, timing angle: 217 ° of 23' ± 15 ', tooth external diameter total run-out: within 0.15, tapering: 0.15%MAX, degree of unbalancedness: 58g cm+/-7.
The preparation method of described car engine timing exhaust cam shaft pulley, comprises the following steps:
1) draw materials under 500T hydraulic press effect, shape in water cooling mold;
2) sinter in continuous sintering furnace, sintering temperature 1120 DEG C, guipure speed 110mm/min, atmosphere RX;
3) it is processed processing in 550T sizing rolling machine;
4) product examine;
6) cleaning, clean medium is trichloro ethylene, ultrasonic cleansing;
7) shipment.
Beneficial effect: compared with prior art, car engine timing exhaust cam shaft pulley of the present utility model, by finite element analysis, part simulation is calculated, find and meet part function most and be easy to the part shape manufactured, the Density Distribution of part each several part is strictly controlled when shaping, part is made to meet degree of unbalancedness requirement, can be used to offset the imbalance of camshaft, thus reducing the vibrations of electromotor entirety, it is made to operate more steady, can effectively solve the vibrations produced when running up that the disequilibrium of camshaft causes, compare the engine vibration without this design less, operate more steady, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of car engine timing exhaust cam shaft pulley.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, this utility model is described further.
Car engine timing exhaust cam shaft pulley of the present utility model, by finite element analysis, part simulation is calculated, find and meet part function most and be easy to the part shape manufactured, as shown in Figure 1, structure mainly includes the gear teeth 1 and 3 spokes 2, each spoke shape is different, quality also differs, the Density Distribution of part each several part is strictly controlled when shaping, part is made to meet degree of unbalancedness requirement, can be used to offset the imbalance of camshaft, thus reducing the vibrations of electromotor entirety, it is made to operate more steady, can effectively solve the vibrations produced when running up that the disequilibrium of camshaft causes, compare the engine vibration without this design less, operate more steady.It is provided with abnormity keyway 3 preferably in one of them spoke, abnormity keyway 3 centrage with the centerlines of another spoke (fan-shaped spoke) within the scope of 115 ° ± 5 °, now imbalance is by the difformity of 3 spokes, makes Mass Distribution unbalanced and is formed, it is easy to make.
The preparation method of this car engine timing exhaust cam shaft pulley, comprises the following steps:
1) draw materials under 500T hydraulic press effect, shape in water cooling mold;The powder metallurgy of camshaft pulley consists of: Fe: surplus;Cu:1.5 ~ 3.9%;C:0.3 ~ 0.6%;Impurity is less than 2%.
2) sinter in continuous sintering furnace, sintering temperature 1120 DEG C, guipure speed 110mm/min, atmosphere RX;
3) it is processed processing in 550T sizing rolling machine;
4) product examine;
6) cleaning, clean medium is trichloro ethylene, ultrasonic cleansing;
7) shipment.
The car engine timing exhaust cam shaft pulley Progressive symmetric erythrokeratodermia of final preparation can be detected, and concrete outcome parameter is as follows:
Density: 6.6g/cm3Above, perpendicularity: within ⊥ 0.025mm, timing angle: 217 ° of 23' ± 15 ', tooth external diameter total run-out: within 0.15, tapering: 0.15%MAX, degree of unbalancedness: 58g cm+/-7.
Car engine timing exhaust cam shaft pulley of the present utility model, by finite element analysis, part simulation is calculated, find meet most part function and be easy to manufacture part shape, shape time strictly control part each several part Density Distribution (sectional wheel radiant density compare other two wheel the high 0.1 ~ 0.2g/cm of radiant density3Each spoke centre is symmetrical, Density Distribution is uniformly), make part meet degree of unbalancedness requirement, it is possible to be used for offsetting the imbalance of camshaft, thus reducing the vibrations of electromotor entirety, make it operate more steady, can effectively solve the vibrations produced when running up that the disequilibrium of camshaft causes, compare the engine vibration without this design less, operating is more steady, has good practicality.
