Abstract

The invention brings forward an oil cylinder driven power set, which comprises at least one hydraulic cylinder, a crankshaft and a fixed part. wherein the hydraulic cylinder comprises a cylinder, a piston and a piston rod. The cylinder is swingably arranged on the fixed part. The piston is fixedly connected with a first end of the piston rod. The crankshaft comprises a main journal and a rod journal, wherein the main journal is arranged on the fixed part; a second end of the piston rod is arranged on the rod journal, and the integral body forms a crank link mechanism to convert straight reciprocating motion of the piston rod into rotary movement of the crankshaft. According to the invention, the crankshaft is driven through hydraulic pressure to output rotary movement. The oil cylinder driven power set has advantages of large output torque, stationary operation, no offset load and overall stroke operation, is convenient to control, has a simple structure, is easy to implement, and is especially suitable for low-speed and large-torque application environment.

Description

technical field

[0001] The invention mainly relates to the field of power system and hydraulic pressure, in particular to a power device driven by an oil cylinder, in particular to a power device with high output torque. Background technique

[0002] In commonly used power devices such as diesel engines and gasoline engines, the cylinder is the source of its driving force. Fuel burns inside the cylinder to propel figure 1 The piston 11' shown moves, and then through the transmission of the connecting rod 12' and the crankshaft 2', the power is output to the corresponding executive components. The connecting rod 12' is the connecting part connecting the piston 11' and the crankshaft 2'. During the working process, the small end of the connecting rod 12' reciprocates with the piston 11', and the large end of the connecting rod 12' revolves around the crankshaft with the connecting rod journal of the crankshaft. The axis of 2' rotates, and the shaft between the big and small ...
