195、2100等小型柴油机除少数用马达启动外,大多数靠手摇启动。在农忙季节,一个人要照看1～2台车,每当作业开始时,启动后一人挂皮带既别扭又危险,若挂上皮带后再启动,则太费劲。此外作业中如需暂停动力,由于没有离合装置,要么把皮带卸下,否则就得灭车。我们在2100小座机上改装了一套离合装置,通过一年来操作使用,效果很好。改装方法简单,用料少,基层单位都能做到,结构见图。滑轮可以铸造,也可以用铁木结构。其直径与座机动力轮一般大;轮宽为皮带宽的1.5倍。轴承可选用换下来的旧滚珠(206)或用铸 195,2100 and other small diesel engines except for a few started with a motor, most of the start by hand. In a busy season, a person to take care of 1 to 2 trolley, whenever the job started, after the start of a hanging belt is both uncomfortable and dangerous, if the belt after hanging start, it is too strenuous. In addition, if you need to suspend power during operation, you should either remove the belt or remove the belt because there is no clutch device. We retrofitted a clutch set on a 2100 small plane that worked well for a year and worked well. Conversion method is simple, less materials, grass-roots units can do, the structure shown in Figure. Pulleys can be cast, you can also use iron wood structure. Its diameter is generally large with the power wheel base; wheel width of 1.5 times the belt width. Bearings can be used to replace the old ball (206) or cast
