Abstract

An annular hydraulic cylinder comprises an upper end cover (3) and a lower end cover (19). The upper end cover (3) and the lower end cover (19) are connected through six bolts (13) and six nuts (14), wherein the bolts and the nuts are evenly and circumferentially distributed. An annular hydraulic cylinder oil cavity (4), an annular piston rod (5), a piston (12) and a fixed stopping block (8) are arranged in the space between the upper end cover (3) and the lower end cover (19). The annular hydraulic cylinder further comprises an output shaft (11), wherein one end of the output shaft is connected with the upper end cover (3), and the other end of the output shaft sequentially penetrates through the annular piston rod (5) and the lower end cover (19) to stretch out of the lower end cover. The annular hydraulic cylinder has the advantages of being convenient to manufacture, compact in structure, low in fault rate, good in sealing performance and good in dynamic property.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to an annular hydraulic cylinder. Background technique [0002] The hydraulic cylinder is the core component of the hydraulic control system and is widely used in industry. It can convert the small power input by the motor into the high power output by the hydraulic pressure, so as to output high power and stability to the equipment. [0003] At present, the rack structure swing cylinder is commonly used to convert the linear reciprocating motion of the traditional hydraulic cylinder into the swing motion. The principle of the swing cylinder is to convert the reciprocating motion of the hydraulic cylinder into the positive and negative directions of the gear shaft through the gear rack. Swing and rotate, while converting the thrust of the reciprocating hydraulic cylinder into the output torque of the gear shaft. [0004] However, the failure rate of the rack-and-pinion ...
