Description
A kind of fluid coupling relates to mainly and adheres to the fluid clutch of realizing clutch action by liquid.
Fluid coupling is to utilize liquid kinetic energy to come a kind of power formula hydraudynamic drive equipment of transmitted power.Traditional variable speed fluid coupling has two types at present: a kind of is the inlet adjusting formula, has the rotation oilcan, utilizes the scoop tube lift adjustment to enter coupler rotor chamber oil mass, and the coupler weight supporting is on motor and working machine and without casing; Another kind is the outlet regulating formula, and coupler is supported on the fixing casing, has to carry or external oil feed pump, and external refrigeration filtering oil-way system utilizes the scoop tube telescopic adjustment to discharge the oil mass in coupler rotor chamber.The fluid coupling of above-mentioned two kinds of structures all will be regulated rotating speed by scoop tube, and lubricated, fuel feeding, cooling and the discrete setting of speed adjustment system, so structure is looser, and required parts are more.
At above-mentioned deficiency, the purpose of this utility model provides a kind of box-type variable speed fluid coupling, and its compact structure, all parts all can be contained in the casing.
Adopt such technological scheme according to the purpose of model utility: fluid coupling comprises pump impeller, turbine, rotation case, pump impeller and turbine symmetric arrangement, in wheel, have many radial radiations and with the blade of parallel axes; On pump impeller and turbine, be connected with input shaft and output shaft respectively; Pump impeller, turbine, rotation case all are positioned at static housing, and input shaft, output shaft stretch out in static housing, and disc links with pump impeller, and rotation case rotates with input shaft, and are enclosed in outside the turbine, have oil injecting nozzle in the bottom of rotation case; Fuel tank is installed in the static housing, and guiding valve is equipped with in the fuel tank bottom, and the handle on the guiding valve stretches out static housing, and conductor is equipped with facing to the position of guiding valve in the fuel tank below, so that the oil in the fuel tank is flowed in the rotation case; Guide plate is equipped with facing to the position of disc in the top in the static housing.
The utility model rotational speed regulation is used guiding valve without scoop tube, and each parts of coupler are placed within the fixing casing jointly, so structure is simple relatively, compact, and required parts are less, solved coupler leakage of oil problem basically.
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is the cut-away view according to the box-type variable speed fluid coupling that the utility model proposes.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
This device comprises a static housing (13), and pump impeller (2), turbine (6), rotation case (11), fuel tank (8) are installed in the described casing.Pump impeller and turbine symmetric arrangement, in wheel, have many radial radiations and with the blade of parallel axes.On pump impeller and turbine, be connected with input shaft (1) and output shaft (10) respectively, and described input shaft and the output shaft the other end stretch out in static housing.Input shaft and motor link, and load machines such as output shaft and water pump or blower fan link.The same pump impeller of disc (3) (2) links, in static housing above facing to the position of disc guide plate (4) being housed, so that in the oily oriented flow oil sump tank that has got rid of by disc.Rotation case (11) rotates with input shaft, generally is connected on the disc (3), also can be connected in pump impeller (2) and go up or directly be connected on the input shaft (1).And rotation case is enclosed in outside the turbine (6), and fluid can be stored among pump impeller and the turbine.For fluid can be flowed out, have oil injecting nozzle (5) in the bottom of rotation case.Guiding valve (7) is equipped with in the fuel tank bottom, and the handle on the guiding valve stretches out static housing, so that the opening degree of regulating slide valve reaches the purpose that adjusts oil mass.Conductor (9) is equipped with facing to the position of guiding valve in the fuel tank below, thereby the oil in the fuel tank is flowed in the rotation case.In the static housing bottom, the disc both sides preferably install oil guide slot (12) again so that by disc get rid of to around fluid can flow back in the fuel tank more easily.On the top cover of static housing, preferably open a through hole, can prevent that the casing internal pressure is too high on the one hand, can in fuel tank, refuel easily on the other hand.Because coupler is in running, the temperature of fluid can rise to some extent, therefore is preferably in the water cooling tube that immerses in the oil is installed in the fuel tank, perhaps loads onto radiated rib at the static housing outer wall.
During this coupler rotor, the power of motor is passed to pump impeller (2) by input shaft (1), passes to the load machine by output shaft (10) after the effect of fluid passes to turbine (6).Working oil in the fuel tank of top flows into active chamber between coupler pump impeller (2) and the turbine (6) by manual guiding valve (7) control back, again oil injecting nozzle (5) discharge on the rotation case (11) through linking with pump impeller.The aperture of regulating slide valve can be regulated the output speed of oil mass in the active chamber or turbine.The fluid that flows out oil injecting nozzle and fall bottom half is around throwing back under the disc that connects with pump impeller (3) drive, flow into the top fuel tank by the guiding of guiding gutter (12) and guide plate (4), again after water composite cooling pipe in being immersed in oil and the cabinet exterior heat radiation cooling, flow into the coupler rotor chamber through guiding valve control again, and so constantly circulation.
