As shown in fig. 5, in a lever, the ball pair O is a middle fulcrum, the ball pair a is a load output point, and the ball pair B is an input driving point. It can be seen that, when the same force and distance are output, the longer AO and BO are, the smaller the swing angle of the lever is, and the smaller the frictional loss at the O point is, and similarly, the smaller the spherical diameter of the O point is, the smaller the frictional distance is, and the smaller the loss is. However, at the same time, the greater the stress of the ball pair, the higher the strength of the rod member is required. The same occurs for ball pairs a and B.
The distance between AO is small relative to the length OB, so the force is large at A, O and small at ball set B. Therefore, the driving is carried out at the position B, the input radial force can be greatly reduced, and the bearing capacity of the whole speed reducer is improved. As long as the strength at AO meets the requirement, the whole speed reducer can work normally. In addition, the number of the levers can be increased properly to share the load, so that the working load is further improved, different lever lengths, lever thicknesses and ball diameters can be selected under different use conditions, namely different component strengths are selected, and a reasonable balance can be sought among the volume, the efficiency and the torque.
