曲柄压力机一般都装有摩擦离合器与制动器。离合器与制动器的布置可分为三类:①离合器、制动器均置于两支承之间;②离合器置于两支承之间,而制动器悬于压力机的后方;③离合器、制动器都悬臂安置在压力机的前、后方。这三类布置都有旋转进气头密封装置,前两类布置又需旋转轴进气密封装置。这两种装置的结构及工作性能直接影响离合器、制动器的工作状态和压力机能否正常工作。我厂在压力机的使用和维修过程中,对这两种装置的结构进行了多次改造,取得了良好效果。
Crank presses are generally equipped with friction clutches and brakes. Clutch and brake arrangement can be divided into three categories: ① Clutch, brakes are placed between the two bearings; ② clutch placed between the two bearings, and the brake hanging in the rear of the press; ③ clutches, brakes are placed in the cantilever pressure Machine before and after. These three types of arrangements have a rotary intake head seal, the first two types of arrangements need to rotate the shaft intake seal. The structure and working performance of these two devices have a direct impact on the working conditions of the clutches and brakes and whether the press can work normally. I plant in the press the use and maintenance process, the structure of these two devices conducted several transformations, and achieved good results.
