活塞型盘式离合器设计
摘要: 活塞型盘式离合器的基本特点在于其摩擦副的工作表面为环状平面,而摩擦片在工作时沿轴向移动,气室主要是推盘的气缸和活塞所组成,活塞与离合器体的法兰连成一体。工作时,压缩空气沿通道进入气室,使气缸(推盘)移动,挂合离合器。气动摩擦离合器(简称气离合器)是一种通用的机械传动部件,其主要功用是使工作机启动平稳,便于换挡以及过载保护。对气离合器的使用要求也和其他离合器一样,要求它工作可靠,挂合平稳,摘开迅速,散热性好,使用寿命长,结构简单轻巧,制造维护方便。由于气离合器不仅具有一般摩擦离合器操作平稳,可在机器运转过程中挂合和过载保护的优点,而且传动更柔和(利用空气的缓冲效果),操作更加迅速,方便,省力,易于实现远距离集中控制,因而在石油钻机上获得了广泛的应用。
本文的主要内容是根据设计要求完成了离合器的总体设计,通过对离合器的结构方案分析对比,对其结构形式,基本尺寸和主要参数进行了设计,并对活塞型盘式离合器的各零部件进行选型和校核计算。

The design of the clutch piston disc
Abstract: Piston-type clutch basic characteristics of the work in its surface friction ring plane, while the friction plate at work along the axial movement. Push plate chamber is posed of cylinder and piston, the piston and the clutch body flange fused. When its work, pressed air into the chamber along the channel, so that the cylinder (push plate) mobile, hanging together clutch. Air friction clutch (referred to as air clutch) is mon mechanical ponents, and its main function is to make a smooth start working machine, easy to shift, and overload protection. The use of gas clutch and clutch requirements as to require it is reliable and stable hanging together, picking open quickly, good heat dissipation, long life, simple structure, light, manufacturing and maintenance. As the gas clutch friction clutch operation is not only stable in general, can be linked to the process is running, the advantages of joint and overload protection, and drive more gently (the use of air cushion effect), the operation is more rapid, convenient, energy, easy to implement long-range focus control, and therefore on the oil rig to obtain a wide range of applications.
  The main content is based on the design requirements plete the overall design of the clutch, the clutch through the analysis parison of the structure of the program, its structure, basic dimensions and main parameters of the design, and piston-type disc ponents for each Selection and verification of the calculation.
