本文指出苏联杜盖尔斯基在推导夹钳轮传动公式里的力学概念错误,因而推得的公式在理论上是错误的。提出了正确的公式。并指出Marik公式是本公式的特例。还证明在架空索道夹钳轮所选用的参数内,本公式或Marik公式均可化为简单的公式—欧拉公式,其最大误差很小。最后还指出一个在计算中不应忽略的问题和一个计算方面的小错误。 This paper points out that the concept of mechanics in the Soviet Union Dugueskii’s derivation of the formula of the torque transmission in the clamp-type wheel is wrong. Therefore, the formula deduced in theory is wrong in theory. Put forward the correct formula. It is pointed out that the Marik formula is a special case of this formula. It has also been shown that this formula, or Marik’s formula, can be turned into a simple formula called Euler’s formula, with the maximum error being very small, within the parameters chosen for the ropeway clamp wheel. Finally, it points out a problem that should not be neglected in the calculation and a minor error in the calculation.
