Problems solved by technology

However, the existing one-way clutches often have the top teeth of the driving gear and the large flywheel, resulting in severe wear of the driving gear
In order to prevent the top tooth phenomenon, in the production of the driving gear, the end of the driving gear in contact with the large flywheel is generally made into a bevel to reduce the contact surface between the driving gear and the large flywheel, but in actual use, it often occurs Top tooth phenomenon, causing grinding damage to the drive gear

Embodiment 1

[0014] Embodiment 1: as figure 1 , 3 , shown in 4: after various parts are made according to the designed shape, the straight-tooth key 16 is processed on the inner wall of the hollow shaft 4, and the helical spline is processed at the place where the movable sleeve 7 is to be installed, so that the movable sleeve 7 is pushed forward When rotating with the angle of the helical spline, the friction copper sheet 9, the friction steel sheet 8 and the movable spacer 11 are successively installed on the movable sleeve 7, and the friction copper sheet 9 and the friction steel sheet 8 are overlapped layer by layer, and the The inner circumferential teeth of the friction steel plate 8 mesh with the keyway on the movable sleeve 7, and are fastened by the spring 10 and the positioning pin 12, and are installed on the hollow shaft 4 together, and then a flat washer 13 and a snap ring 14 are used to secure it. Fix it, insert it into the drive shell 6, and make the internal helical spline...

Embodiment 2

[0015] Embodiment 2: as figure 2 As shown, in the one-way clutch formed in Embodiment 1, the inner cavity of the hollow shaft 4 is respectively processed into a drive pinion movable cavity 15, a spring telescopic cavity 17 and a push rod cavity 18, and on the inner wall of the drive pinion movable cavity 15 A straight-toothed key 16 is set, and one end of the driving pinion 2 is also processed into a corresponding straight-toothed key 19, and the driving pinion 2 inserted in the movable cavity 15 of the driving pinion is connected with the straight-toothed key on the hollow shaft 4 through the straight-toothed key 19 16 meshes.

Abstract

This invention discloses a one-way clutch which meshing gear will not push out. It consists of drive gearshaft, friction sheet steel, friction sheet copper, moving sleeve, springs, fitting pins, moving filling pieces, flat filling pieces, snap rings and drive shell. Through matching the spur gear keys with hollow axle, the drive gearshaft is inserted into the expanding inside of the hollow axle in order to make the drive gearshaft move lengthwisely inside the drive gearshaft of the hollow axle. With the inner spiral keys on the inner surface of the drive shell, the drive gearshaft will rotate when progressing. The rotation can mesh the drive gear and big flywheels. The advantages are prolonging the life of one-way clutch and reducing the production cost and use-cost.

Description

technical field [0001] The invention relates to the field of starter manufacture on an internal combustion engine, in particular to a one-way clutch with the function of protecting meshing teeth. Background technique [0002] The one-way clutch is an important part of the starter on an internal combustion engine such as a car, and it realizes the function of the starter. However, the driving gear and the top teeth of the large flywheel often occur in the existing one-way clutch, thereby causing severe wear of the driving gear. In order to prevent the top tooth phenomenon, in the production of the driving gear, the end of the driving gear in contact with the large flywheel is generally made into a bevel to reduce the contact surface between the driving gear and the large flywheel, but in actual use, it still often occurs Top tooth phenomenon, causing grinding damage to the drive gear. Contents of the invention [0003] The technical problem to be solved by the present inv...
