一、棘轮机构的组成部份及其用途：棘轮机构是顿巴斯－１型采煤康拜因牵引部传达电动机动力及调速的一个重要机构。为此，棘轮机构是由棘轮，工作插爪，制动插爪，小轴，弹簧及调速板组成的。（见图１） 二、棘轮强度的计算： １．工作插爪和棘轮的啮合点：当工作插爪和棘轮工 First, the ratchet mechanism components and their use: ratchet mechanism is a Donburi-1 Coal Kang Baine traction motor to convey motor power and speed an important body. For this reason, the ratchet mechanism is composed of a ratchet, a working insert, a brake insert, a small shaft, a spring and a speed control plate. (See Figure 1) Second, the calculation of ratchet strength: 1. Engagement point of working claw and ratchet: When working claw and ratchet work
