Embodiment

[0017] When the glue injection plunger 3 is in the high pressure area of ​​the curved guide rail 1, the rotor body 4 is connected to the high pressure oil in the plunger cavity, and under the action of the high pressure oil, the glue injection plunger 3 is pushed out of the rotor plunger cavity, so that the roller 2 is in close contact with the rotor body. On the curved guide rail 1, and roll along the downward extension direction of the curved guide rail 1. When the injection plunger 3 is in the low-pressure area of ​​the curved guide rail 1, it is connected to the low-pressure oil return in the plunger cavity of the rotor body 4. Since the pressure in the low-pressure area is lower than that in the high-pressure area, the rollers receive thrust when the curved guide rail 1 rises and the rollers 2 Push the injection plunger back into the rotor plunger chamber.

[0018] The original plunger is all made of metal parts, and the moment of inertia formed during the movement is rel...

Abstract

The invention relates to a glue-injecting plunger structure for a hydraulic motor. The glue-injecting plunger structure comprises a rotor body, a roller and a glue-injecting plunger. A plunger cavity is vertically formed in the rotor body. An oil inlet is formed in the lower end of the plunger cavity, wherein one side of the oil inlet communicates with an oil-way. The glue-injecting plunger is vertically inserted and arranged in the upper portion of the plunger cavity. The glue-injecting plunger comprises a metal body and a glue-injecting body. The glue-injecting body is arranged at the lower end of the metal body. The roller is arranged at the upper end of the glue-injecting plunger. The upper end of the roller is arranged on a curve guide rail. The glue-injecting plunger structure has the characteristics of reducing the rotary inertia of the hydraulic motor, reducing the inertia of the plunger and the like.

Description

technical field [0001] The invention relates to the technical field of hydraulic motor plungers, in particular to a glue injection plunger structure for hydraulic motors. Background technique [0002] At present, the hydraulic motor industry generally uses solid metal plungers for hydraulic motors. The solid metal plunger can meet the requirements in use, but it increases the inertial force of the plunger and increases the moment of inertia of the hydraulic motor. The use of hydraulic motors increases the time during the braking process, which reduces the rigidity of the hydraulic system. In order to solve this problem, it is necessary to design a glue injection plunger. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a glue injection plunger structure for hydraulic motors, which effectively reduces the quality of the working plunger, reduces the inertia force of the plunger during the operation of the hydraulic...
