Problems solved by technology

Therefore, there is a large gap between the pitch curve adopted by the non-circular gear in the hydraulic motor and the ideal theoretical curve.
[0006] 2. The structural design of the motor is unreasonable
Due to the use of rear body distribution, not only the structure of the motor is very complicated, the weight increases, and oil leakage is prone to occur, but also because the motor can only be output by shaft rotation, the motor needs to change its motion through a series of transmission mechanisms under many working conditions. Form can only be used, which greatly increases the transmission chain and reduces efficiency; even in some occasions it cannot be used at all

Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, the shell-rotating hydraulic motor of the present invention includes a mandrel 10, a heart wheel 11 sleeved on the mandrel 10, a peripheral wheel 5 and a non-circular gear train composed of 7 planetary gears. There is an oil inlet 1 on the mandrel 11. , oil outlet 2, also have front body 3, rear body 7, sealing ring 9, bearing 8, front and rear body 3,7 to be fastened and connected by screw 6 in addition. The number of the periphery of the heart wheel is three, the number of the periphery of the peripheral wheel is four, the triangular heart wheel 11, and the quadrilateral peripheral wheel 5 are formed as figure 2 The knot curves shown are unique. Six flow distribution holes 12 are opened on the heart wheel 11 and distributed symmetrically, the number of which is twice the number around the heart wheel 11 . The heart wheel 11 is fixedly connected with the mandrel 10 , and the hydraulic oil enters the heart wheel 11 through the ...

Abstract

This invention discloses a non-round gear planetary wheel system shell rotary hydraulic motor, which contains oil intake, oil outlet, front unit, rear unit, core wheel, cycle wheel, planetary wheel and core shaft featuring the core shaft is fixed and the shell is rotated, flow distributed hole is holed in core shaft and its number is two times of the number of cycle of core wheel, the cycle wheel and core wheel forming unique section curve. Said invention has simple making process, large torsion, stable driving, low noise and fine sealability.

Description

technical field [0001] The invention belongs to the technical field of planetary gear hydraulic power actuators, and in particular relates to a low-speed high-torque hydraulic motor with a non-circular gear planetary train casing. Background technique [0002] Low-speed high-torque hydraulic motor is a widely used hydraulic actuator. Its structure is various. The common ones are plunger motor, vane motor, inner curve motor and non-circular gear hydraulic motor. They are usually based on Output torque in the form of shaft rotation. In particular, the non-circular gear planetary gear train hydraulic motor is a relatively new form of hydraulic motor. Patent No. 151883 in Poland in 1971, Patent No. 3852002 in the United States in 1972, and Patent No. 90104412.1 in China in 1990 are all patents for this motor. The structure and principle are described. The non-circular gear planetary gear train hydraulic motor disclosed in the above patent documents ...
