Abstract
The invention discloses a disc type rotor stacking and splicing inner curve low-speed large-torque hydraulic motor. A rotor is of a split structure, and the structure is composed of a plurality of sets of rotors; and the rotors are arranged in the axial direction of a main shaft and are combined and fixed together through an inner spline and an outer spline. Due to the structure, the machining technology of the rotors is good, the requirement for machining equipment is reduced, the machining requirement can be met by using general equipment, the investment capital of the equipment is reduced, the machining cost is reduced, and batch production is facilitated. The rotor structure is used as a key component of the hydraulic motor, and through the improvement of the rotor structure and the technology, the manufacturing cost of the inner curve low-speed large-torque hydraulic motor is reduced.
Description
Technical field
The present invention relates to a kind of disk rotor inner curve low speed high torque hydraulic motor of oil hydraulic motor field, particularly relate to the inner curve low speed high torque hydraulic motor that spelling folded by a kind of disk rotor.
