Abstract
The utility model discloses a curved-surface-undercut one-way clutch. A sliding shaft (5) is penetratingly disposed on a belt pulley (1), a curved-surface fixed tooth (2) and a curved-surface sliding tooth (3) to form the surface-undercut one-way clutch through a sliding shaft sleeve (4). The curved-surface fixed tooth (2) is fixed on the belt pulley (1) through screws. The curved-surface sliding tooth (3) matches with the curved-surface fixed tooth (2) through a sliding spring (6), a bearing, an oil seal, key pins and a washer. The curved-surface fixed tooth (2) is provided with a curved surface having an undercut. The undercut curved surface of the curved-surface sliding tooth (3) matches with the curved surface of the curved-surface fixed tooth (2). A combing pawl of the curved-surface sliding tooth (3) matches with a combining pawl of the sliding shaft sleeve (4). The surface-undercut one-way clutch is simple in structure. The curved-surface fixed tooth is in surface-undercut fit with the curved-surface sliding tooth, and accordingly the surface-undercut one-way clutch is low in slipping coefficient, firm in combining, high in torque, high in strength, resistant to wear and long in service life.
Description
Technical field
The utility model relates to clutch, is specifically related to a kind of curved surface reverse buckling type one-way clutch.
Background technology
In recent years, along with improving constantly of Tendency of Agricultural Machinery in China level, agricultural machinery is being brought into play key effect in agricultural production, and agricultural manufacturing industry has also obtained significant progress.As everyone knows, grain header is one of agricultural machinery commonly used, and the work under bad environment of grain header often runs into problems such as high temperature, mire, pasture and water winding, ceding of Taiwan obstruction, causes the ball-type clutch not wear-resistant, and service life is short, and maintenance cost is high.
Summary of the invention
The purpose of the utility model is: a kind of curved surface reverse buckling type one-way clutch is provided, and curved surface rotation spring is auxiliary, in conjunction with firm, and long service life, maintenance cost is low.
The technical solution of the utility model is: this clutch comprises belt pulley, curved surface fixed teeth, curved surface slide teeth, sliding shaft sleeve and sliding axle; Sliding axle is installed on belt pulley, curved surface fixed teeth, the curved surface slide teeth through the sliding shaft sleeve penetration type and constitutes clutch; Wherein, The curved surface fixed teeth is fixed on the belt pulley through screw, and the curved surface slide teeth cooperates the curved surface fixed teeth through sliding spring, bearing, oil sealing, key pin and pad, establishes the curved surface of band back-off on the curved surface fixed teeth; The curved surface of the band back-off of curved surface slide teeth cooperates the curved surface of curved surface fixed teeth, and the engagement pawl of curved surface slide teeth cooperates the engagement pawl of sliding bearing.
During use; The rotational slide axle; Sliding axle drives the sliding shaft sleeve displacement, the engagement pawl of the engagement pawl interlock curved surface slide teeth of sliding shaft sleeve, curved surface slide teeth displacement simultaneously; Assisting down of sliding spring, the curved surface of curved surface slide teeth is combined together by curved surface fixed teeth, curved surface slide teeth through the curved surface of back-off interlock curved surface fixed teeth.
The utility model is simple in structure, and the curved surface fixed teeth is the curved surface reverse buckling type with the curved surface slide teeth and cooperates, and the coefficient that skids is low, in conjunction with firm, and high pulling torque, high strength, wear-resistant, the long-life, operation effectiveness is good.
