The invention relates to an internally and externally combined mechanical self-locking hydraulic cylinder, which comprises a cylinder body, a piston slidably connected to the cylinder body, a piston rod fixedly connected to the piston, and an internal self-locking hydraulic cylinder arranged inside the cylinder body. component, an external self-locking component arranged outside the cylinder, and a housing sleeved on the external self-locking component, the housing is respectively connected to the cylinder and the external self-locking component, so The piston rod has a tooth portion arranged on its surface, the external self-locking assembly includes a gear and a gear brake connected to the gear, the gear meshes with the tooth portion, and the gear brake is connected to the housing physically. In the present invention, an internal self-locking component and an external self-locking component are respectively arranged inside and outside the hydraulic cylinder to realize joint internal and external locking of the hydraulic cylinder, ensuring high precision and high reliability of the long-term working position of the hydraulic cylinder.
Description
technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to an internal and external combined mechanical self-locking hydraulic cylinder. Background technique [0002] Hydraulic transmission is widely used in agricultural machinery, construction machinery, aerospace and other occasions because of its high power density, easy to achieve stepless speed regulation, standardization, and high degree of automation. Hydraulic cylinder is an important component widely used in modern industrial hydraulic industry. Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has a simple structure and reliable operation. When the hydraulic cylinder is used to realize the reciprocating motion, the reduction device can be omitted, and there is no transmission gap, and the movement is stable, so it is widely used in various mechanical hydraul...
