Radial plunger type multiple-action inner curved hydraulic motor

Abstract

The invention relates to a radial plunger type multiple-action inner curved hydraulic motor, which is hydraulic equipment mainly applicable to stokeholes and other severe working environments. The hydraulic motor mainly comprises an output shaft, an installation seat, gear rings, a plunger piston, a driving disk, a rear seat, an oil pan, a brake, a brake axle, and the like. Tracks of the motor adopt the gear rings processed by a single curve track formula so as to meet plunger piston movement, the use of multiple types of sealing rings can avoid obvious leakage between a high pressure chamber and a low pressure chamber, and meanwhile, miniature leakage rate can meet the requirement of a bearing on lubrication, thereby guaranteeing that a machine can not be damaged due to overtemperature in the process of running.

Description

technical field [0001] The invention relates to a hydraulic motor, in particular to a radial cylinder suitable for severe working conditions, in which the unstable change of the hydraulic system has less influence on its use, and the oil cavity seal is less affected by the hydraulic system. Plug type multi-action internal curve hydraulic motor. Background technique [0002] The hydraulic motor is a hydraulic driving method with a wide range of applications. At present, the hydraulic motors used in the furnace equipment usually use oil seals to seal the oil. However, the hydraulic system piping of the blast furnace equipment is long, and the hydraulic system is often unstable. At present Oil leakage and oil seal failure of the hydraulic motor often occur in the use of the blast furnace. At the same time, the environment in front of the blast furnace is harsh, resulting in a short service life of the conventional motor. At the same time, the traditional track curve of this ty...

[0002] The hydraulic motor is a hydraulic driving method with a wide range of applications. At present, the hydraulic motors used in the furnace equipment usually use oil seals to seal the oil. However, the hydraulic system piping of the blast furnace equipment is long, and the hydraulic system is often unstable. At present Oil leakage of hydraulic motors and failure of oil seals often occur in the use of hydraulic motors. At the same time, the environment in front of the blast furnace is harsh, resulting in a short service life of conventional motors.

At the same time, the traditional track curve of this type of hydraulic motor is a combined curve, and the transition of the curve between the acceleration section and the deceleration section usually has a certain impact on the flow rate of the motor.
