Embodiment Construction
[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0035] Such as figure 1 As shown, the left housing 1, the right housing 1' and the middle housing 10 constitute the closed cavity of the hydraulic transformer; the rotating shaft 11 is mounted on the left and right housings 1, 1 through the left bearing 13 and the right bearing 13' respectively. 'in the bearing chamber, the left and right plunger cylinders 6, 6' are connected to the rotating shaft 11 through the left and right driving pins 8, 8' respectively, and the axes of the left and right plunger cylinders 6, 6' are connected to the axis of the rotating shaft 11 The axes are in the same plane, and the angle α=8° is formed. Under the action of the high-pressure oil source, the left and right plungers 9, 9' undergo telescopic movement in the left and right plunger chambers 7, 7' respectively, driving the left and right plungers. , the righ...

The invention discloses a hydraulic pressure transformer with two cylinder bodies, and belongs to the technical field of hydraulic parts. The hydraulic pressure transformer with the two cylinder bodies is characterized in that a left outer disc with left outer disc inner teeth is arranged outside a boss of a left inner disc with left inner disc first outer teeth and left inner disc second outer teeth in a sleeving mode; the right end surface of the left outer disc and the left end surface of the boss of the left inner disc are attached to the left end surface of a left plunger cylinder; the left inner disc is connected with a left shell body through a left positioning pin; the left outer disc is connected with a left swinging motor rotor through a left spline; a right outer disc with right outer disc inner teeth is arranged outside a boss of a right inner disc with right inner disc first outer teeth and right inner disc second outer teeth in a sleeving mode; the left end surface of the right outer disc and the left end surface of the boss of the right inner disc are attached to the right end surface of a right plunger cylinder; the right inner disc is connected with a right shell body through a right positioning pin; and the right outer disc is connected with a right swinging motor rotor through a right spline. The hydraulic pressure transformer with the two cylinder bodies has the advantages that the hydraulic pressure transformer has a large transformation ratio, the instant flow fluctuation is small, vibration and noise are effectively lowered, and servo control is easy to achieve.
Description
technical field [0001] The invention belongs to the technical field of hydraulic components, and in particular relates to a hydraulic transformer with double cylinders. Background technique [0002] The constant pressure network secondary regulation technology is a very important energy-saving solution in the field of hydraulic transmission today. The hydraulic transformer is the core component of the secondary regulation technology of the constant voltage network. Innas company applied for the invention patent of WO9731185A1. In this patent, the distribution plate of the hydraulic transformer is evenly arranged with three waist-shaped grooves, which are respectively connected with the constant voltage source, the load and the low voltage source. "The Development Status of Hydraulic Transformers" summarizes the technical problems of hydraulic transformers, which are "control problems", "vibration and noise", and "interface problems between the distribution plate and the rea...
