Abstract

The invention relates to a hydraulic transformer, in particular to an electrically controlled clino-axis piston hydraulic transformer. The hydraulic transformer of the invention aims at solving the problems that the current hydraulic transformer is mainly controlled by hands and is inconvenient for operation and difficult for ensuring precision. The front end of a transitional plate (4) of the invention is arranged in the lower part of a shell body (9) and connected with a port plate (2); the rear end of the transitional plate (4) is connected with a main shaft (6) of the port plate; a rear end cover (5) is arranged on the main shaft (6) of the port plate and fixedly connected with the shell body (9); the front end surface of the rear end cover (5) mutually contacts the rear end surface of the transitional plate (4); a driven gear (11) on the transitional plate (4) is meshed with a driving gear (12) on a gear shaft (3); the gear shaft (3) is connected with the outputting end of an servo motor (7) by a coupler (8). The servo motor is adopted in the invention to control the rotating angle of the driven gear by the gear shaft; servo control is introduced, thus not only having convenient operation, but also being capable of realizing precise control and improving the controlling performance of a system.

Description

technical field [0001] The invention relates to a hydraulic transformer. Background technique [0002] Existing hydraulic transformers are mainly controlled manually. The principle is that the manual control lever is coaxial with the driving gear, and the driven gear is controlled by the manual control lever, that is, the rotation angle of the hydraulic transformer distribution plate is controlled to realize voltage transformation. The disadvantage of manual control is that the operation is inconvenient and the accuracy is difficult to guarantee. Contents of the invention [0003] The purpose of the present invention is to provide an electronically controlled inclined-axis plunger type hydraulic transformer to solve the problems that the existing hydraulic transformer is mainly controlled manually, the operation is inconvenient, and the accuracy is difficult to guarantee. [0004] The invention includes a plunger pump, a flow distribution plate, a gear shaft, a rear end c...
