Abstract
The utility model belongs to a hydraulic clutch which transfers moment by using a liquid medium to form pressure. The utility model is characterized in that A body (6) (of the clutch (6) (also a belt wheel) is provided with one to a plurality of volumetric pumps, a driving shaft of the volumetric pump is meshed with a gear (4) fixed on a driving shaft (7) of an actuator by a gear (3), and an oil outlet of the volumetric pump is provided with a valve (5). The utility model has the advantages of simple structure, easy fabrication, stable combination, no noise, energy saving, sensitive and reliable operation, etc.
Description
The utility model is the novel hydraulic clutch.
The novel hydraulic clutch is to put forward on existing friction clutch exists the basis of serious deficiency.The deadly defect of friction clutch is: skid, frictional heating, easy scaling loss; Complex structure, boundary dimension are big; Friction plate costs an arm and a leg; Adjustment and displacement workload are big or the like.
The purpose of this utility model is to design a kind of novel hydraulic clutch that overcomes the above-mentioned deadly defect of existing friction clutch existence, this novel clutch has simple in structure, in conjunction with steadily, advantage such as noise free, saving energy, life-span be long, can offer large-scale crank press, horizontal forging machine, hotdie forging press and flying shear and realize service intermittent.
This novel hydraulic clutch action principle is finished by mechanism design cleverly, its main points are: be provided with one to several displacement pumps in the body (also being belt pulley) of clutch, the transmission shaft of displacement pump is meshed with gear on being fixed on actuator's transmission shaft with gear, oil outlet at pump is installed a valve, when valve is opened, belt pulley (body of clutch) rotation, small gear rotates round the gearwheel on actuator's transmission shaft on the transmission shaft of pump, pump is promptly worked, and plays recycle oil.This moment, the actuator transmission shaft was motionless, promptly clutch be in " from " state.When valve was shut, the oil outlet of pump was blocked, and the pressure chamber of pump forms high pressure.Small gear can not rotate round the gearwheel on actuator's transmission shaft on the transmission shaft of pump, so actuator's transmission shaft and clutch (belt pulley) constitute one, the belt pulley rotation drives actuator's transmission shaft rotation, the work of work actuator, this is that clutch is in the state of " closing ".
The principle of above-mentioned hydraulic coupling also can design one therein and realize to several radial plunger pumps to several gear pumps or.
Fig. 1 is for including screw pump hydraulic coupling schematic representation
Fig. 2 is for including axial piston pump hydraulic coupling schematic representation
Embodiment 1:
Fig. 1 has designed several screw pumps in clutch, be referred to as to include the screw pump hydraulic coupling.
The working principle of inner screw pump hydraulic coupling now is described by Fig. 1, promptly this clutch from, close state.Motor drives the housing rotation of clutch by belt, initiatively screw rod (1) end gear (3) will be rotated round the gearwheel (4) on actuator's transmission shaft (7), initiatively screw rod (1) drives driven screw rod (2) (also can be designed to 2) rotation, and liquid medium is pressed against hyperbaric chamber A from low-pressure cavity B screw slot.When control valve (5) during in open mode, hydraulic medium by chamber A by valve (5) to chamber B, again by chamber B to chamber A, the like this circulation.This moment, liquid medium can not form high pressure at chamber A, and initiatively the gear (3) on the screw rod (1) is gone up gearwheel (4) rotation round actuator's transmission shaft (7), and actuator's transmission shaft is motionless, clutch be in " from " state.Be closed as control valve (5), liquid medium can not must form high pressure so by chamber A to chamber B in the A of chamber.Active and driven screw rod just can not rotate.Promptly initiatively the gear (3) of screw rod end can not be around the rotation of the gearwheel (4) on actuator's transmission shaft, so belt pulley (clutch outer member 6) constitutes one with actuator's transmission shaft (7), belt pulley (clutch outer member 6) rotation, drive actuator's transmission shaft (7) rotation, the work of work actuator, promptly clutch is in the state of " closing ".
Embodiment 2:
Fig. 2 has designed one or several axial piston pumps in the novel hydraulic clutch, be referred to as to include the axial piston pump hydraulic coupling.Be meshed with gearwheel (7) on the actuator transmission shaft having designed gear (6) on the pump drive shaft.Designed control valve (8) at delivery side of pump, when valve (8) during in open mode, belt pulley (clutch outer member) is driven to rotate, gear (6) is around gear (7) rotation, be that pump drive shaft drives cylinder body (4) rotation, because the effect of swash plate (1) and piston shoes (2) makes generation to-and-fro motion such as plunger (3).When plunger was in the figure lower position, constantly toward overhanging, the sealed volume of plunger base constantly increased plunger, form parital vacuum, fluid in the clutch (communicating with atmosphere) is under the barometric pressure effect, and the waist shaped hole of process thrust plate (5) enters the bottom of plunger, finishes oil suction; And the plunger of bitmap top then constantly contracts inwards, and the sealed volume of plunger base constantly reduces, and the fluid pressurized is discharged through another waist shaped hole of thrust plate (5), finishes pressure (row) oil.Inlet port communicates in clutch with oil drain out.In such cases, the transmission shaft of actuator is motionless.Clutch be in " from " state.The shell of clutch is a belt pulley, also is flywheel.
When valve (8) when being closed, Ya Suo plunger is inactive inward.Then cylinder body can not rotate, can not rotate with the pump drive shaft of cylinder body rigid joint, and small gear can not be around the gearwheel rotation, belt pulley and actuator's transmission shaft constitute one like this, the motor moment of rotation, can be directly passed to actuator's transmission shaft, Here it is clutch is in " closing " state.
This invention has advance, practicability and science.Advance finds expression in hydraulic medium formation pressure comes carry-over moment; That practicability shows is simple in structure, easy to manufacture, in conjunction with steady noise free, save energy, handle sensitive reliable; Scientific performance is to adopt in the hydraulic coupling hydraulic element of (or design), all is long-tested, practical and reliable, all reaches perfection in theory with on the manufacturing process; And science also shows it cleverly on the structural design, during this clutch work, and " closing "---carry-over moment, " from "---clutch integral body becomes the flywheel of a stored energy.Therefore this invention is all to have very important significance at scientific progress or on application in practice.
