Double-stator swing hydraulic multi-speed motor

Abstract

The invention discloses a double-stator swing hydraulic multi-speed motor. n raised inner and outer motor fan-shaped moving blades (33 and 31) are respectively arranged on the inner and outer surfaces of a ring-shaped rotor (2) of the double-stator swing hydraulic multi-speed motor; n raised inner motor fan-shaped fixed blades (32) are arranged on the outer surface of an inner stator (1); n raised outer motor fan-shaped fixed blades (30) are arranged on the inner surface of an outer stator (3); the inner stator (1) is arranged in a die cavity of the ring-shaped rotor (2); and the ring-shaped rotor (2) is arranged in a die cavity of the outer stator (3). The double-stator swing hydraulic multi-speed motor works stably, is small in size, light in weight and high in specific power, and is easy to process and manufacture; and by adoption of the double-stator swing hydraulic multi-speed motor, different inner and outer swing motors with a plurality of discharge capacities are realized in one shell, wherein the discharge capacities of the inner and outer swing motors have a certain proportional relation, and through different combinations of the inner and outer swing motors, the swing motors can output a variety of angular speeds and torques.

Description

technical field [0001] The invention relates to a hydraulic variable volume machine, in particular to a double-stator swing hydraulic multi-speed motor. Background technique [0002] Swing hydraulic motor, as an important actuator that can make the load obtain 360° reciprocating swing motion without any speed change mechanism, is being increasingly widely used in various industries. Various existing swing hydraulic motors can only output one angular velocity when the input flow rate is constant. In order to change the output angular velocity of the motor, components such as a variable pump or a throttle valve must be used to change the input flow of the motor. As a result, the efficiency of the system is reduced, the cost is increased, and the structure is complicated. Existing swing motors are all swing motors with one rotor corresponding to one stator and only one pair of oil inlet and outlet ports. There is only one connection method, and differential connection cannot ...

As a result, the efficiency of the system is reduced, the cost is increased, and the structure is complicated

Existing swing motors are all swing motors with one rotor corresponding to one stator and only one pair of oil inlet and outlet ports. There is only one connection method, and differential connection cannot be realized, so it is difficult to realize a wide range of speed and torque changes, which greatly limits the swing Scope of application of hydraulic motor
