Description

Tool for installing piston

Technical Field

The utility model relates to the technical field of piston installation, in particular to a tool for installing a piston.

Background

The inner curve radial piston hydraulic motor is a low-speed high-torque hydraulic motor and is widely applied to working conditions such as coal machine markets, reverse well drilling machines, crushers and the like.

In the inner curve radial piston hydraulic motor, the most critical component is a rotor piston component assembly, and oil entering the system pushes the piston to do work through an orifice of a rotor, so that an externally connected spline shaft is driven to be output to corresponding equipment, and the conversion of hydraulic energy and kinetic energy is realized. Because the rotor is accurate with the cooperation of piston, in order to prevent that fluid from leaking out from the gap between piston and the rotor, seal with elastic sealing ring, not only reduced the leakage of fluid like this, but also be easier with heat transfer for the oil liquid to circulate than the sealing member of general material. However, when the piston assembled by the piston ring is installed in the rotor, the piston ring is difficult to install, and has small size, good elasticity and strength, and only a user can press the piston ring by hand to carefully squeeze the piston ring into the rotor hole, so that the efficiency is low, the finger strength of the worker is required to be high, and the handle is easy to be injured when a large amount of operations are performed.
