Abstract
A push-type transmission mechanism has a base, a plurality of fixing discs securely mounted on the base, and a driving component rotatably mounted on the base. The driving component includes a plurality of cam portions. Each fixing disc has a plurality of driven rolling components which can move in radial directions of the fixing discs and can protrude out of outer surfaces by abutment of the cam portions. An inner surface of a transmission block forms a corrugation structure extending continuously in a circumferential direction. The corrugation structure is abutted by the driven rolling components. Thus, speed is changed through the driven rolling component connecting to the corrugation structure. Besides, with the driven rolling components driven by the cam portions, power can be transmitted with high torque.
Claims15
A push-type transmission mechanism comprising:
- a power transmission assembly comprising:
- a base;
- a first fixing disc being an annular object, an end surface of the first fixing disc mounted on the base, and the first fixing disc comprising:
- a plurality of first limiting portions arranged in a circle, spaced apart from each other at intervals, and protruding from an edge of another end surface of the first fixing disc;
- a plurality of driven rolling components, part of the driven rolling components mounted in the intervals of the first limiting portions and being capable of moving in radial directions of the first fixing disc;
- a driving component rotatably mounted on the base and comprising:
- a first cam portion formed on an outer surface of the driving component and abutting on said part of the driven rolling components that are mounted in the intervals of the first fixing disc;
- and
- a second cam portion formed on the outer surface of the driving component and adjacent to an end surface of the first cam portion;
- and
- a second fixing disc, an end surface of the second fixing disc securely connected to the base and facing toward the first fixing disc, the second fixing disc comprising:
- a plurality of second limiting portions arranged in a circle, spaced apart from each other at intervals, and protruding from an edge of the end surface of the second fixing disc;
- the first limiting portions and the second limiting portion staggered with respect to each other;
- the remaining driven rolling components, which are other than the ones mounted on the first fixing disc, mounted in the intervals of the second limiting portions and being capable of moving in radial directions of the second fixing disc;
- each one of the remaining driven rolling components abutting on the second cam portion of the driving component;
- a cover mounted on the base, sleeved on the first fixing disc, and forming:
- an opening at a center of the cover;
- and
- an output assembly comprising:
- a transmission block rotatably mounted between the second fixing disc and the cover, and forming:
- an output component protruding from a surface of a first end of the transmission block and mounted in the opening of the cover;
- and
- a corrugation structure formed continuously in a circumferential direction of an inner surface of a second end of the transmission block opposite the first end of the transmission block, the driven rolling components being capable of abutting the corrugation structure.
