Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] see Figure 1-4 , the present invention provides a technical solution: a combined gear structure, including a mounting hole 2, the mounting hole 2 is set on the middle inner wall of the gear 1, the inner wall of the mounting hole 2 is fitted with a rotating shaft 3, and the outer side of the rotating shaft 3 is equipped with a positioning Institution 4.
[0023] The positioning mechanism 4 includes a block 401, a roller 402, a pin shaft 403, a swash pl...

The invention discloses a combined gear structure which comprises a mounting hole, the mounting hole is formed in the inner wall of the middle of a gear, the inner wall of the mounting hole is in clearance fit with a rotating shaft, and a positioning mechanism is mounted at the outside of the rotating shaft. Compared with the prior art, the combined gear structure has the following advantages that through cooperation of the gear, the mounting hole, the rotating shaft, a clamping block, ta roller, a pin, an inclined plate, a round block, a shell and a torsion spring, the rotating shaft drives the clamping block to be inserted into the shell, the clamping block applies an outward force to the roller, and the roller drives the inclined plate to rotate outwards through the pin and the round block so that the torsion spring can be compressed; on the contrary, the roller can be reset to clamp and locate the clamping block through the elasticity of the torsion spring so that the rotating shaft is accurately located in the mounting hole in the gear, the mounting deviation is avoided, the stable transmission of the gear is ensured, and the problems that when a conventional combined gear structure is used, the gear and the shaft cannot be located and mounted, the mounting deviation is easy to occur, and the transmission is influenced are solved.
Description
technical field [0001] The invention relates to the technical field of gear structures, in particular to a combined gear structure. Background technique [0002] Gears refer to the mechanical elements with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. With the development of production, the stability of gear operation has been paid attention to. It is used in combination with the shaft, but when the existing combined gear structure is in use, the gear and the shaft cannot be positioned and installed, and the installation deviation is prone to occur, which affects the transmission. It can only be installed on the matching shaft and has a single function. Contents of the invention [0003] The purpose of the present invention is to provide a combined gear structure to solve the problem that the existing combined gear structure proposed in the above background technology cannot po...
