Problems solved by technology

[0003] The existing one-way device assembly is generally composed of gear parts, collars, oil seal pressure rings, star wheels, rollers, casings, etc. The oil seal pressure ring and gear parts are in hard contact, causing serious wear and tear during work. The gap between the two will become larger and larger, resulting in oil leakage, which seriously affects the quality of use; the contact surface between the star wheel and the gear part is prone to movement, resulting in a gap between the two and direct oil leakage, which seriously affects the quality of use; The material of the technical bushing is ordinary copper bushing without any treatment, resulting in a short service life. The existing one-way device generally has a service life of 35,000 times, which cannot meet the demand for long life.

Embodiment Construction

[0012] Such as figure 1 , figure 2 As shown, a checker assembly includes: a gear part 1, a collar 2, an oil seal pressure ring 3, a star wheel 5, a roller 6, a flat spring 7, and a case 4. The gear part 1 includes a gear 11 and a bushing 12, a bushing 12 is installed on the inner wall of the gear 11, and the bushing 12 is made of tin bronze, a high-strength wear-resistant material. The evenly distributed diamond-shaped pits are installed in the diamond-shaped pits with graphite blocks of the same shape, and the graphite blocks are used to improve the friction resistance; the material of the oil seal pressure ring 3 is rubber material with strong wear resistance and sealing; the roller 6 and the flat spring 7 are put into the curved surface cavity of the star wheel 5 and injected with an appropriate amount of lubricating grease. The oil seal pressure ring 3 is spread on the star wheel 5, and the gear part 1 slides into the star wheel through the roller 6. In the cavity of th...

Abstract

The invention discloses a one-way device assembly, which comprises a gear component, a retaining ring, an oil seal press ring, a star wheel, a roller, a flat spring and a shell. The gear component comprises a gear and a bush, the bush is mounted on the inner wall of the gear and is selectively made of high-strength wear-resistant materials, a diamond concave pit is arranged on the inner surface of the bush, a graphite block with the shape identical to that of the diamond concave pit is mounted in the diamond concave pit, the oil seal press ring is selectively made of soft materials with high wear resistance and sealing property, the roller and the flat spring are respectively mounted in a curved-surface cavity of the star wheel, the curved-surface cavity of the star wheel is filled with a defined amount of lubricating grease, the oil seal press ring is laid on the star wheel, the gear component slips into the cavity of the star wheel via a surface of the roller, a corresponding concave and convex structure is arranged on a surface, which contacts with the star wheel, of the gear component, so that the star wheel is in close fit with the gear component, the retaining ring is mounted in a gear groove, the shell is sleeved on the retaining ring and tightly wraps the star wheel, and the retaining ring, the oil seal press ring and the star wheel are fixed without loosening. The one-way device assembly has the advantages of leakage resistance, high abrasion resistance, high quality and long service life.

Description

technical field [0001] The invention relates to a one-way device assembly, which is used for an automobile starter. Background technique [0002] The one-way device assembly is a key part of the automobile starter. Its function is to reliably transmit the torque from the starter to the crankshaft of the engine during the starting process and to protect the starter armature from overrunning by its one-way function after the engine is started. High speed and damage, so the quality of the one-way device assembly directly affects the life of the car. [0003] The existing one-way device assembly is generally composed of gear parts, collars, oil seal pressure rings, star wheels, rollers, casings, etc. The oil seal pressure ring and gear parts are in hard contact, causing serious wear and tear during work. The gap between the two will become larger and larger, resulting in oil leakage, which seriously affects the quality of use; the contact surface between the star wheel and the ...
