Two groups of racks drive the racks on a piston oil cylinder or an air cylinder to be engaged with small gears on an input shaft at left and right respectively, the oil cylinder or the air cylinder is controlled by a mechanical control check valve and a hydraulic control reversing valve to drive the piston oil cylinder or the air cylinder driven by the racks to reciprocate automatically and straightly and to lead the small gears engaged with the racks of the oil cylinder or the air cylinder to rotate forwards and reversely, the small gears lead the movable gears of the input shaft and a clutch to rotate forwards and reversely, through reversing by middle gears, the output shaft continuously rotates in one direction. The hydraulic or barometric motor has a simple structure and reliable operation; the oil or air pipelines are provided with hydraulic or barometric control elements such as a speed adjusting valve, a pressure adjusting valve and the like for achieving the functions of the hydraulic or barometric motor with variable torques and variable rotating speeds from low speed to super-low speed.
Description
Affiliated technical field
The utility model relates to a kind of hydraulic pressure or air pressure motor, especially can make the kinetic energy of hydraulic pressure or air pressure convert low speed, high pulling torque hydraulic pressure or the air pressure motor that main axis rotation is moved to.
Background technique
At present, known oil hydraulic motor is can change the hydraulic pressure that oil hydraulic pump produces into rotatablely move a kind of executive component, and oil hydraulic motor has gear type, blade type, axial piston and radial plunger type.The characteristics of gear-type hydraulic motor and vane motor are simple in structure, easy to maintenance, but because sealing is relatively poor, and volumetric efficiency is low, the low-speed running instability can only be the oil hydraulic motor of rotating speed height, little moment of torsion.The characteristics of axial piston and radial piston hydraulic motor are the volumetric efficiency height, can make low-speed big, but complex structure, part number is many, manufacture process requirement height, cost costliness, turbidity test sensitivity and maintenance levels to medium are had relatively high expectations, and generally are applied on the more important equipment.
Summary of the invention
In order to overcome at ask for something is not higher, but needs the equipment needs of low-speed big, and it is a kind of simple in structure that the utility model provides, volumetric efficiency height, low-speed big hydraulic pressure or air pressure motor easy to maintenance.
The technological scheme that its technical problem that solves the utility model adopts is: done reciprocating linear motion by left and right sides tooth bar drive piston oil cylinder, make with the left and right sides meshing small gear of tooth bar piston rod and produce positive and negative rotation motion, small gear makes that input shaft produces positive and negative rotation motion on it, slip fine module gear and slip large module gear are housed on the input shaft, it is big to slide, fine module gear, bearing, compositions such as clutch inner sleeve Wedged piece have positive and negative direction lock to two free wheel devicees, no matter make with the sliding gear input shaft that matches in two free wheel devicees to just or to the opposite direction rotation motion, always there is a sliding gear under the free wheel device locking and just or rotation motion in the other direction.Correspondingly on the output shaft parallel with input shaft mix two fixed gears, wherein a gear is mutually meshing with slip large module gear on the input shaft, another part gear with another part slip fine module gear on the input shaft through mutually meshing behind intermediate gear.The speed ratio of two groups of gears is identical, but the modulus difference of tooth makes its centre distance identical.A sliding gear rotates because of the free wheel device locking on input shaft, another part sliding gear has locking to slide because of Chao gets over Li He Qi No, because of one group of gear wherein is through the intermediate gear commutation, make that corresponding two gears of mixing rotate to same direction on the output shaft.Left and right sides tooth bar drive piston oil cylinder piston alternately starts the left and right sides machine control one-way valve of oil cylinder top dress simultaneously, because machine control one-way valve in the left and right sides links to each other with the pilot operated directional control valve of being made up of spool, valve seat, valve pocket etc., make the pilot operated directional control valve that links to each other reach automatic reverse in one-period, and low speed high torque hydraulic motor can steadily be rotated continuously.The low speed high torque hydraulic motor oil circuit is mixed the former devices of hydraulic control such as series flow control valve, pressure regulator valve, just can realize variable torque, and the low speed of speed variable is to the function of the oil hydraulic motor of ultra-low speed big torsional moment.
The beneficial effects of the utility model are: have variable torque with compositions such as simple piston or stick harness cylinder structure and tooth bar, gear, clutches, the low speed of speed variable is to the oil hydraulic motor of ultra-low speed big torsional moment, and its power source pressurized air has in this way just become air pressure motor.
