许多林业机械——悬挂式挖坑机、旋耕机、植树机等都装有牙嵌安全离合器,以便过载时保护机械部件的安全。但是,这种离合器的主要缺陷是灵敏度太低,以至仍有损坏机件的现象发生。因此,提高安全离合器灵敏度是设计这类林业机械不可忽视的一环。利用圆锥螺旋弹簧受力——变形不遵守虎克定律的特点,可对现有牙嵌安全离合器进行改进。以提高其灵敏度。 Many forestry machinery - hanging digging machines, rotary tillers, tree planting machines, etc. are equipped with claw safety clutch, in order to protect the safety of mechanical parts overload. However, the main drawback of this type of clutch is that the sensitivity is so low that damage to the mechanism can still occur. Therefore, to improve the safety clutch sensitivity is the design of such forestry machinery can not be ignored. The use of conical coil spring force - deformation does not comply with the characteristics of Hooke’s law, the existing tooth-embedded safety clutch can be improved. To increase its sensitivity.
