Abstract

A ring plug type electro-hydraulic actuator belongs to the technical field of hydraulic power. A bearing, an oil distribution sleeve, a spring, a ring plug, a guide ring, a swash plate, a driving ring, a swash plate, a guide ring, a ring plug, a spring, an oil distribution sleeve, a spring, a ring plug, a guide ring, a swash plate, a driving ring, a swash plate, a guide ring, a ring plug, a spring, an oil distribution sleeve and a bearing are sequentially arranged on a hydraulic pump stator from left to right in a sleeving manner, a piston of a piston rod assembly is arranged in an oil cylinder in a seal sliding manner, a piston rod at one end of the piston rod assembly penetrates through a through hole in the center of a seal end cover in a seal sliding manner, and a piston rod at the other end of the piston rod assembly penetrates through a through hole in the center of a connector end cover in a seal sliding manner. The ring plug type electro-hydraulic actuator is high in integration degree, rapid in piston rod action and reaction and high in conversion efficiency, and belongs to a mechanical, electrical and hydraulic integrated product. Internal leakage between high and low pressure oil cavities is little, and the self-sucking capability is strong.

Description

technical field [0001] The invention belongs to the technical field of hydraulic power. Background technique [0002] Hydraulic systems play an important role in modern industrial technology. At present, most typical hydraulic systems are composed of hydraulic auxiliary components such as hydraulic pump stations, hydraulic cylinders, valve groups and pipelines. Typical hydraulic systems have the following shortcomings: high maintenance requirements for hydraulic systems; high requirements for manufacturing precision of hydraulic components; Difficult maintenance; difficult manufacturing, high cost; large overall volume and quality of the system; hidden dangers of external leakage; not suitable for long-distance transportation, etc. The hydraulic pump station is connected to the motor through a coupling, which has the following disadvantages and deficiencies: noise and energy loss caused by the cooling fan of the motor; noise and vibration caused by the non-concentricity of ...
