Abstract
The utility model relates to a roller transmitting force pintle valve hydraulic motor, comprising a shell body (2), a plunger piston body (3) and a connecting rod (4); the roller transmitting force pintle valve hydraulic motor is characterized in that: the roller transmitting force pintle valve hydraulic motor also comprises a blank cap (1), a rolling ball (5) and a pintle valve (6), the blank cap(1) is connected on the shell body (2), the plunger piston body (3) and the connecting rod (4) are arranged in the shell body (2), the rolling ball (5) is connected with the connecting rod (4), and the pintle valve (6) is arranged in the shell body (2). Roller force transmission is adopted by a crank shaft eccentric wheel, the friction line speed of the connecting rod is reduced, the abrasion isreduced and the mechanical efficiency is improved; a hole type shell body of a plunger type cylinder reduces a plunger piston sleeve and adopts a blank cap type, the whole weight of the motor is reduced, and the high pressure and the impact property of the motor are improved; the high pressure and the impact property of the motor are improved by the pintle valve; the processing difficulty is reduced and the performance and quality ratio are improved.
Description
Technical field
The utility model relates to a kind of oil hydraulic motor, particularly a kind of roller force transmission shaft flow-metering oil hydraulic motor.
Background technique
Now, the connecting rod of hydraulic motor line friction velocity that a lot of manufacturers use is big, and wearing and tearing are many, and mechanical efficiency is low; The oil hydraulic motor overall weight is big; Motor high pressure and impact property are poor.
Summary of the invention
Solve the above-mentioned technical problem that oil hydraulic motor exists, and a kind of roller force transmission shaft flow-metering oil hydraulic motor is provided.
For achieving the above object, the technical solution of the utility model is as follows:
Roller force transmission shaft flow-metering oil hydraulic motor comprises housing, plunger body, connecting rod, it is characterized in that, also comprise stifle, ball, pintle, stifle is connected on the housing, and plunger body, connecting rod are placed in the housing, and ball and connecting rod link together, and pintle is placed in the housing.
Beneficial effect:
The crankshaft eccentric wheel adopts the roller power transmission, reduces connecting rod friction linear velocity, reduces wear, improves mechanical efficiency; Plunger case cellular type housing reduces plunger bushing, adopts the stifle formula; Alleviate the motor overall weight, improve motor high pressure and impact property; Axle flow form improves motor high pressure and impact property; Reduce difficulty of processing, improve the performance quality ratio.
