Problems solved by technology
[0002] Gears are common mechanical parts in people's lives. Through mutual meshing and transmission, the existing gears mainly include a circular gear body, with a shaft hole in the center of the gear body, and a ring gear on the outer profile of the gear body. Ordinary The shape of the gear is relatively simple, and the friction between the external gear body and the internal gear body is relatively large during use, which not only leads to greater resistance but also wears between the external gear body and the internal gear body, the service life is short, and it cannot meet various requirements. needs

The invention relates to a built-up gear part. The built-up gear part comprises an outer gear body, trapezoidal sawteeth, an inner gear body and pointed sawteeth; the outer side of the inner gear bodyis sleeved with the outer gear body; a round slide rail is installed on the periphery of an inner cavity of the outer gear body, and the surfaces of the upper side and the lower side of an inner cavity of the round slide rail are both provided with slide grooves; a ring is installed on the periphery of the inner gear body, and elastic devices are installed on the periphery of an inner cavity of the ring. According to the built-up gear part, the ring and the round slide rail are connected in a matched mode, and thus, the inner gear body can drive the ring to slide in the round slide rail; balls cooperate with the slide grooves, thus, the ring can drive the balls to slide in the slide grooves, and friction force between the outer gear body and the inner gear body is decreased; and resistance is reduced, in addition, the situation that the outer gear body and the inner gear body abrade each other is avoided, the service life is prolonged, and various requirements can be met.
Description
technical field [0001] The invention relates to the technical field of mechanical transmission components, in particular to a combined gear component for a gear device. Background technique [0002] Gears are common mechanical parts in people's lives. Through mutual meshing and transmission, the existing gears mainly include a circular gear body, with a shaft hole in the center of the gear body, and a ring gear on the outer profile of the gear body. Ordinary The shape of the gear is relatively simple, and the friction between the external gear body and the internal gear body is relatively large during use, which not only leads to greater resistance but also wears between the external gear body and the internal gear body, the service life is short, and it cannot meet various requirements. demand. Contents of the invention [0003] The purpose of the present invention is to provide a combined gear part to solve the problems raised in the background art above. [0004] In o...
