Embodiment
With reference to the accompanying drawings 1, shown in the accompanying drawing 2, input shaft 2 one ends are supported on the input bearing 3 of the input shaft bearing 4 that is installed on the casing 14, the other end is supported on the shell on the back bearing 15 at ladder place of the output shaft bearing 9 that is installed on the casing 14, on the excircle of shell on the back, have 2～3 holes, deep fat in the active chamber (hydraudynamic drive has 1.5%～3% hydraulic losses) is discharged, and oil pump is thrown cold oil into the coupler rotor chamber, realizes thermal equilibrium.Pump impeller 5 rigid joint in the front end of input shaft and the casing, the rear end connects with prime mover.One end of output shaft 10 is supported on the output bearing 13 of cascade output shaft bearing 9 front ends that are installed on the casing 14, the other end is supported on the output bearing 12 of stepped shaft bearing 9 rear ends, turbine 8 rigid joint in the front end of output shaft 10 and the casing, the rear end of output shaft connects with working machine.During work, input shaft is by motor drives and drive pump impeller 5 rotations, the pump impeller that has many radial blades quickens and pours the turbine 8 that has many radial blades with pump impeller equally with the centrifugal in the active chamber, drive the rotation of turbine and output shaft, thereby give the load that is attached thereto transmission of power.Liquid in the active chamber is provided by oil-way system, and oil feed pump sucks working oil and behind supercooler 23, enters oil rectifier 21 from 20 li of fuel tanks, and after the filtering, part oil is for bearing lubrication, and another part oil enters two-position three way magnetic valve 16.When electromagnetic valve during in the I position, the oil that enters two-position three way magnetic valve is oil sump tanks 20 all, do not have oil in coupler rotor the chamber in, realize disengaging fully; When electromagnetic valve during in the II position, the oil that enters two position three-way valve is by two-position two-way solenoid valve 17 controls.When two-position two-way solenoid valve was logical, oil entered in the coupler rotor chamber by two-position two-way solenoid valve, and active chamber is oil-filled entirely, realized the function of combination; When two-position two-way solenoid valve closed, oil entered in the coupler rotor chamber by electromagnetic proportional valve 18 parts, and the active chamber part is oil-filled, played the effect of limit square.When the coupler part was oil-filled, its overload torque reduced, and as 30% when oil-filled, under the stuck situation of working machine, motor torque is about 90% of specified carry-over moment.The control of oil-way system can be adopted the interactive automatic control system of PLC Programmable Controller, also can adopt the three-way valve manual control system.The input end of working machine is equipped with tachometer (or moment instrument), when working machine transships, signal is transferred to control system, control system is sent instruction, the oil mass that control enters active chamber by electromagnetic proportional valve realizes that part is oil-filled, and the position of electromagnetic proportional valve is debugged setting in advance, thereby play the effect of limit square, realize the function of overload protection; Perhaps oil-filled by manual three-way valve control.
Advantage of the present invention is that axial dimension is little, be difficult for to produce vibrations, adopts the valve control oil-filled, realize from and function, and overload protection function is arranged.
