Inserting type gear

Abstract

The invention discloses a plug-in gear, which comprises a base wheel with a shaft hole in the center. The base wheel includes a left base wheel and a right base wheel fixedly connected coaxially, and the right base wheel is near the left base wheel. The outer circular surface is evenly spaced with right insertion slots arranged axially along the right base wheel, and the corresponding insertion slots of the left base wheel are provided with symmetrical left insertion slots, and the left insertion slot and the right insertion slot The size and structure of the slots are the same and the cross-section is L-shaped. A tooth block is fitted in each of the insertion slots. The tooth block includes a gear tooth part and an insertion joint that is respectively matched with the left insertion slot and the right insertion slot. The cross-section of the tooth part is trapezoidal, and the insertion part is inserted and fixed in the left insertion groove and the right insertion groove. The plug-in gear provided by the invention has simple structure, compact plug-in connection, gear teeth can be replaced at any time according to needs, and the use and maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a plug-in gear. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. Due to the good reliability and strong bearing capacity of gear transmission, transmission gears are widely used in machinery, instrument and other manufacturing industries. In all kinds of heavy machinery, gears are often used for transmission. In the long-term practical process, tooth surface wear and tooth damage are prone to occur. Ordinary one-piece gears cannot be disassembled. In the event of wear and tear, only the entire gear can be replaced, resulting in increased mechanical use and maintenance costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a plug-in gear with simple structure, compact plug...
