Background

The gear refers to a mechanical element which is provided with a gear on a wheel rim and continuously meshed with the gear to transmit motion and power. The gear transmission is a common power transmission device with low cost, has the advantages of stable movement, cleanness, low noise and the like, and is widely applied. The gear can be divided into gear teeth, tooth grooves, end faces, normal faces, addendum circles, dedendum circles, base circles, reference circles and the like according to the structure. The steels commonly used for manufacturing gears include quenched and tempered steels, quenched steels, carburized and quenched steels, and nitrided steels. The existing gear needs the matching of a connecting device and the connection and fixation of a rotating rod, and the independent taking and the installation of a flat key are troublesome. The traditional integral gear needs to disassemble the shaft and then axially disassemble the gear, and inevitably needs to disassemble a large amount of related parts at the same time, so the disassembling and reassembling process is very troublesome and the replacing time is long.
