[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. Gears are widely used in daily life and industrial production. Gears can be seen in automobiles, clocks, elevators, gas meters and other equipment. However, existing gears still have defects and deficiencies in some aspects that need to be improved:

[0003] For example, a high-strength gear with application number: CN202223308276.5 relates to the field of gear technology, including a gear body, the outer surface of the gear body is sleeved with a gear sleeve, one side of the gear sleeve is fixedly installed with a mounting plate, a fixing bolt is rotatably connected between the mounting plate and the gear body, a keyway is provided at the middle position of the surface of the gear body, a threaded hole is provided on the surface of the gear body, and the threaded hole is meshed with the fixing bolt, the fixing bolt is equidistantly distributed on the gear body and the mounting plate in a circumferential state, through holes are provided around the mounting plate, and the middle part of the gear sleeve is a hollow structure. In actual use, by arranging the gear body, the gear sleeve, the mounting plate, the fixing bolt and the keyway, and by installing the gear sleeve on the outer surface of the gear body, the strength of the gear teeth is effectively improved, which plays a role in protecting the gear teeth. At the same time, the gear sleeve can be quickly removed from the gear body, which is convenient for people to maintain it.

[0004] Most of the gears in the above documents are fixed by connecting and processing the rotating shaft, end face and gear. When the gear is in operation, it is impossible to further limit and fix the two, and the connection between the two is not tight enough. When the speed of the gear is high, the two may become loose, thereby reducing the stability of the gear operation. At the same time, the strength of the gear itself is not high, and the loose gear will cause wear to itself to a certain extent, thereby reducing the service life of the gear.

[0005] So we proposed a high-strength compact gear to solve the above-mentioned problems. Utility Model Content

[0011] A movable groove is provided on the inner side of the end surface, a fixed rod is fixedly connected inside the movable groove, and a limit block is nested and connected inside the movable groove;

[0012] The outer end of the limit block is fixedly connected with a clamping plate, and a buffer spring is fixedly connected between the outer side of the clamping plate and the movable groove, and a rotating rod is hinged between the clamping plate and the driving plate.

[0013] Furthermore, the nested block forms an elastic structure through a reset spring and an end surface, and the nested block forms an integrated structure through a pull rod and a driving plate, and the rotating rod forms a rotating structure through a driving plate and a locking plate.

[0014] Furthermore, the limit block forms a sliding structure through the clamping plate and the movable groove, and the clamping plate forms an elastic structure through the buffer spring and the movable groove, and the inner side of the clamping plate can be nested and clamped with the fixing rod.

[0015] Furthermore, the reinforcing mechanism includes an auxiliary ring, which is fixedly connected to the top of the reinforcing ring, and the inner side of the auxiliary ring is nested with auxiliary balls, and the outer side of the auxiliary ring is fixedly connected with a supporting plate;

At this time, the locking plate can be relatively engaged with the fixed rod, and the fixed rod limits the driving plate, and further limits the nesting block to prevent the nesting block from continuously moving outward due to centrifugal force and colliding with the gear bar.
