Embodiment Construction
[0014] The technical solutions of the present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. It can be understood that the experimental examples described here are only used to explain the present invention, not to limit the present invention.
[0015] In this embodiment, an external gear with a variable number of teeth includes an external gear mounting seat (1), a double-tooth mounting block (2), a single-tooth mounting block (3), and a mounting block stopper (4). The center of the gear mounting seat (1) has a shaft hole (12), and the outer ring of the external gear mounting seat (1) has a mounting block guide groove (10), and the side of the mounting block guide groove (10) has a 43° guide groove fan The ring notch (9), the left side of the notch of the fan ring of the guide slot (9) is a threaded blind hole (8), the right side of the notch of the fan ring of the guide slot (9) is a through hole (11), an...

The invention discloses an external gear with variable tooth number. The external gear includes an external gear mounting seat, a double-teeth mounting block, a single-tooth mounting block and a mounting block stop piece; an axle hole is formed in the center of the external gear mounting seat, a mounting block guide groove is formed in the outer ring of the outer gear mounting seat, a guide groovefan ring notch is formed in the side face of the mounting block guide groove, a threaded blind hole is formed in the left side of the guide groove fan ring notch, and a through hole is formed in theright side of the guide groove fan ring notch; and the double-teeth mounting block and the single-tooth mounting block enter the mounting block guide groove through the guide groove fan ring notch andare connected with the external gear mounting seat, two gear teeth are arranged on the outer surface of the double-teeth mounting block, one gear tooth is arranged on the outer surface of the single-tooth mounting block, a through hole is formed in the middle of the single-tooth mounting block, and the mounting block stop piece is mounted in the guide groove fan ring notch through bolts. According to the external gear with variable tooth number, the number of the gear teeth of the gear is changed easily, the number of teeth can be quickly changed to meet the speed ratio change needs of the design and development phase of the gearbox by adopting the structure, and the production costs are reduced accordingly.
Description
technical field [0001] The invention relates to an external gear with a variable number of teeth, belonging to the technical field of gear structures. Background technique [0002] In the mechanical industry, power transmission is a very important part, and gear transmission is one of the important transmission mechanisms. It has the advantages of relatively accurate transmission, high efficiency, compact structure, reliable operation and long life. [0003] At present, in the design process of the gearbox, when the speed ratio of the gearbox changes, the number of teeth of the gear needs to be changed quickly, and the previously processed gears also become waste products, resulting in a waste of resources. Therefore, an urgent solution is needed. Contents of the invention [0004] The object of the present invention is to address the above problems and propose a variable number of teeth external gear to solve the problem of waste of resources due to the need for speed rat...
