[CN 201820527110.7] Elbow Joint Swing Hydraulic Motor for All-Sea Deep Hydraulic Manipulator
[CN 201820527110.7] Elbow Joint Swing Hydraulic Motor for All-Sea-Depth Hydraulic Manipulator Title: Elbow Joint Swing Hydraulic Motor for All-Sea-Depth Hydraulic Manipulator Application Number: CN 201820527110.7 Applicant: Hangzhou Yukong Electromechanical Engineering Co., Ltd. Application Date: 2018-4-13 Patent Type: Utility Model The utility model relates to the transformation and utilization of plunger hydraulic motor, and aims to provide an elbow joint swing hydraulic motor for all-sea-depth hydraulic manipulator. Including: the motor housing and the motor end face distribution plate of the multi-acting inner curve radial piston hydraulic motor, the inside of the motor output shaft is provided with an oil return distribution channel, an oil inlet distribution channel and a distribution channel that provide flow distribution and power distribution to the subsequent structure driven by the swing hydraulic motor; In the original three oil ports of the multi-acting inner curve radial piston hydraulic motor, the oil inlet and the oil outlet are respectively changed by hard pipe connection, in order to keep consistent with the direction of the flow distribution joint of the motor output shaft; The oil discharge port is blocked with a plug, and the internal channel of the front end cover of the motor is connected with the oil return flow distribution channel to realize the oil discharge inside the motor. The utility model has the functions of current distribution and angle detection, and has the characteristics of compact overall structure, small size, light weight, corrosion resistance, high pressure resistance, low minimum stable rotation speed, and arbitrary limit of swing angle.
