Gear

Abstract

The invention relates to a gear. The gear comprises a gear inner ring and a gear outer ring, a connecting and fixing mechanism is arranged on the gear inner ring, a connecting insertion frame is arranged on the inner wall of the gear outer ring, the connecting insertion frame is detachably connected with the connecting and fixing mechanism, and a connecting branch chain is arranged on the connecting insertion frame. The gear can solve the following problems, existing in the actual using and machining process of an existing gear, that firstly, the shape structure of the existing gear is mostly an integrally-formed structure, the whole gear needs to be manually detached from the mounting position by using a tool in the replacement process, the mounting stability of a gear ring needs to be guaranteed during mounting, a connecting and fixing position is easily damaged due to repeated manual dismounting and mounting of the gear, the stability of the gear after mounting is affected, and the operation is complex when replacement is needed to be carried out on gears with different diameter specifications.

Description

technical field [0001] The invention relates to the technical field of gears, in particular to a gear. Background technique [0002] Gears refer to mechanical elements with gears on the rim that continuously mesh to transmit motion and power. Most of the gears used in mechanical equipment are casted. The casted gears are integrally formed. The formed gears have fixed structural specifications. When it is necessary to change the transmission speed of the gear during production and processing, it is necessary to replace the gear of the corresponding specification. The transmission speed of gears with different diameters and specifications is different during use. The replacement of gears in the processing operation has extremely strict requirements on its stability. [0003] At present, the following problems exist in the actual use and processing of the existing gears. First, the shape and structure of the current gears are mostly integrally formed structures. During the repl...

Problems solved by technology

[0003] At present, the following problems exist in the actual use and processing of the existing gears. First, the shape and structure of the current gears are mostly integrally formed structures. During the replacement process, manual tools are required to remove the entire gear from the installation position. The stability of the installation of the gear ring. Manually dismantling and installing the gear repeatedly will easily lead to damage to the fixed position of the connection, which will affect the stability of the gear after installation. It is complicated to replace the gears with different diameters and specifications.

[0004] In order to better improve the convenience of gear use, related technology R&D personnel have made innovative designs on the structure and use of gears. For example, the patent No. 202010637708.3 is a Chinese invention patent named a gear through the toothed plate and rack. The detachable connection method can meet the requirements of using incomplete gears of different specifications without dismantling the chainring, which improves the stability of the use of the gears. It cannot be solved, so the problem of how to perform stable and fast replacement for gears of different specifications needs to be solved urgently
