Technical Field

The invention relates to the field of transmission structures, in particular to a transmission wheel with a clutch structure.

Background

In a transmission structure, a transmission wheel is an important part, and common transmission wheels comprise belt wheels, chain wheels, gears and the like; in the transmission mechanism, the transmission wheel is generally in transmission connection with a driving device such as a motor, but in a complex application environment, the driving device needs to be connected with a clutch and then connected with the transmission wheel, so that the whole volume of the transmission mechanism is large, and the transmission mechanism is not beneficial to being applied to certain equipment requiring small volume; sometimes, in order to calculate the stroke of the transmission wheel, the driving device is also connected with a stroke meter, and the whole volume of the transmission mechanism is also large.

Disclosure of Invention

In view of the above, the present invention is directed to a transmission wheel with a clutch structure, which can solve the problem that the overall size of the transmission mechanism is large due to the need of connecting the clutch and the transmission wheel together in the driving device.

The technical scheme of the invention is realized as follows:

a driving wheel with a clutch structure comprises a wheel body and a transmission shaft which penetrates through the wheel body and is coaxial with the wheel body, wherein an inner cavity is formed in the wheel body, and an annular inner peripheral wall is formed in the wheel body through the inner cavity; the transmission shaft with the internal perisporium of wheel body forms separation and reunion structure, be equipped with the driving tooth on the periphery wall of wheel body.

As a further alternative of the driving wheel with the clutch structure, the inner cavity is concavely arranged from one end surface of the wheel body, the transmission shaft is sleeved with a damping piece, and the damping piece is arranged on one side of the concavely arranged inner cavity of the wheel body; the inner peripheral wall of the wheel body is concavely provided with a plurality of bayonets, at least one movable roller is arranged in the inner cavity, and the transmission shaft is provided with a shifting piece which is arranged in the inner cavity; the damping member forms a magnetic drag fit with the roller; the roller is engageable with the paddle to snap fit within the pocket.

As a further alternative of the transmission wheel with the clutch structure, one of the damping member and the roller is made of a magnetic material, and the other is made of a magnetic metal material.

As a further alternative of the driving wheel with the clutch structure, a pre-force member is arranged in the arc-shaped opening, abuts against the roller and applies elastic pre-force to the roller to urge the roller to move towards the relatively narrow part.

As a further alternative of the transmission wheel with the clutch structure, the roller is a cylinder or a sphere.

As a further alternative of the driving wheel with the clutch structure, a plurality of magnetic induction pieces which are distributed at equal intervals along the circumferential direction are arranged on one end face of the wheel body.
