Sector gear

Abstract

The invention provides a sector gear. The sector gear comprises a connecting base, wherein a sector fluted disc is fixed to the outer edge of the connecting base through a screw assembly, a rotating shaft is embedded into the middle of the connecting base and is rotationally connected with the connecting base, a sliding groove is formed in the center of the rotating shaft, a movable connecting piece is slidably connected into the sliding groove, a third bolt is arranged on the surface of the movable connecting piece, the threaded end of the third bolt structure penetrates through the movable connecting piece structure and abuts against the surface of the connecting base to fix the position, in the sliding groove, of the movable connecting piece, and a connecting groove used for being connected with a transmission shaft is formed in the middle of the movable connecting piece. The sector gear is provided with the adjustable oval sliding groove like an athletic field and the movable connecting piece, the transmission connecting position of the sector gear can be adjusted through the change of the fixed position and angle of the movable connecting piece and the sliding groove, the transmission position deviates from the circle center of the gear, the eccentric degree can be adjusted to meet different eccentricity requirements, and therefore the sector gear has higher applicability and a good development prospect.

Description

technical field [0001] The invention relates to the field of transmission parts, in particular to a sector gear. Background technique [0002] A sector gear is an incomplete disc gear, and it is called a sector gear because of its shape similar to a fan. It is often used in the reciprocating transmission of mechanical devices. Compared with the complete disc gear, it has the advantages of small size and other advantages. It is often used in precision instruments to improve the compactness of the overall transmission structure and reduce the overall structural volume. [0003] However, in some mechanical devices, it is necessary to use eccentric transmission parts. Through the difference in the distance between the eccentric transmission part edge transmission mechanism and the transmission shaft, the curve change of transmission speed and other specific effects can be realized, and the eccentric sector gear is a non-standard part. , often need to be customized, because the ...

[0003] However, in some mechanical devices, it is necessary to use eccentric transmission parts. Through the difference in the distance between the eccentric transmission part edge transmission mechanism and the transmission shaft, the curve change of transmission speed and other specific effects can be realized, and the eccentric sector gear is a non-standard part. , often need to be customized, because the different requirements for eccentric positions need to be customized each time, which is not universal, resulting in a large increase in manufacturing costs and sales prices
