a sector gear

Abstract

The invention provides a sector gear, comprising a connecting seat, a fan-shaped toothed plate is fixed on the outer edge of the connecting seat through a screw assembly, a rotating shaft is embedded in the middle of the connecting seat, and the rotating shaft is connected to the connecting seat in rotation, and a sliding shaft is arranged in the center of the rotating shaft. Slot, slidingly connects the movable connector in the chute, the surface of the movable connector is provided with a third bolt, the threaded end of the third bolt structure runs through the structure of the movable connector and the surface of the connecting seat interferes with the fixed movable connector in the chute, the movable connection The middle of the part is provided with a connection groove for connecting the transmission shaft. The present invention is provided with an adjustable elliptical chute similar to a track and field field and a movable connector on the sector gear. The fixed position and angle of the movable connector and the chute can be changed. , can adjust the transmission connection position of the sector gear, so that the transmission position deviates from the center of the gear circle, and can adjust the degree of eccentricity to meet different eccentric requirements. It has wide applicability and has 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
