Abstract

The invention discloses a novel gear and relates to the technical field of gears, and the novel gear is used for solving the problem that a gear is inconvenient to mount when a gear shaft cannot rotate. The novel gear comprises a gear plate and a gear seat, wherein a mounting hole is formed in the center of the gear plate; at least three threaded holes are formed in the circumference which takes the center of the gear plate as a circle center; the gear seat is a circular metal plate; a circular boss matched with the mounting hole is arranged at the center of one end face of the gear seat; a wheel shaft hole matched with the gear shaft and a flat key penetrates through the boss and the gear seat; cambered slots are uniformly formed in the gear seat outside the boss along the circumferential direction, and the number of the cambered slots is the same as that of the threaded holes; the multiple cambered slots are respectively opposite to the multiple threaded holes; screws are mounted in the cambered slots and the corresponding threaded holes in a matched manner. The wheel shaft hole is matched with the corresponding gear shaft and the flat key by rotating the gear seat, so that the gear can be accurately meshed, and a driving gear and a driven gear are convenient to mount.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a gear with easy installation. Background technique [0002] In the process of installing the intermeshing gears, when the gear shaft does not rotate flexibly, or the gear shaft cannot rotate, it is difficult to install the gear on the gear shaft through the keyway under the condition of ensuring accurate meshing of the gears. If the gear is first installed on the gear shaft through the keyway, it is difficult for the two gears to ensure more accurate meshing, or even cannot mesh. Especially when multiple gears need to be meshed on a gear shaft, it is relatively difficult to ensure that each gear can be meshed more accurately. Nowadays, gear meshing is used in many places in the machinery industry, and some machines with high precision requirements have higher and higher requirements for the accuracy of gear meshing. Therefore, there is an urgent need for a gear that can ensure a...
