Annotation The operation of well sucker rod pump installations is the most massive way of mechanized oil production. A significant part of the wells equipped with low-speed plants of this type have a low flow rate and high water cut. Such conditions create certain restrictions on updating and modernization of the production fund of equipment in operation. The life cycle of a rocking machine is usually significant and often exceeds 20 years. During ISPR operation, both ground and downhole equipment will inevitably wear out. A significant proportion of failures of the ground part of low-speed ISPR is associated with the reduction of the rocking machine, which is the most responsible and most expensive drive element. The resource of the gearbox directly depends on its load, which is characterized by the moment on its crank (output) shaft. Reducing the maximum torque and moment fluctuations in one full swing of the rocking machine will significantly increase the reliability of the gearbox and the entire installation. This paper describes the mathematical apparatus for calculating the moment on the crank shaft of the gearbox, based on the exact kinematics of the drive and the principle of possible movements. The proposed methodology will allow to solve the problems of designing a balancing drive of a low-speed ISPR, to determine the requirements for the engine and transmission.
