Embodiment
As shown in drawings, make each mechanical part of the utility model hydraulic couplers, prepare electric accordingly, instrument.Because installation precision requires high, this Coupler needs on-the-spot the installation.At first, have good positioning motor 26 and working machine 28, and both shaft centre lines are on the same horizontal axis, and making it fixing, the body of Coupler is in them between the two.The utility model hydraulic couplers comprises box assembly, rotating machinery assembly and oil circulating system assembly, preceding two big assemblies are installed between motor and the working machine, and the rotating machinery assembly comprises input assembly and output precision, are installed in respectively in motor 26 and the working machine 28 extended rotating shafts.Described output precision comprises output shaft 18, turbine A 13, turbine B 14 and turbine backing plate 9, on one side be to have comprised input shaft 4, input labyrinth bush 6, oil-feed dish 7 with what connected, the input assembly of pump impeller A8 and shell 11, be hung on the mounting base of motor 26, on the axle that motor stretches out, use bolt; Another side is that pump impeller B 17 is packed in the output precision with connecting cylinder 15, loads onto output labyrinth bush 19, reinstalls on the axle that working machine 28 stretches out, and uses bolt; Like this, pump impeller A and pump impeller B by connecting cylinder 15 symmetry connections, be positioned at the both sides of input shaft and output shaft, turbine A and turbine B are installed between the two, turbine A and turbine B link together by turbine backing plate 9, are provided with oil-through hole between the two, form an active chamber by pump impeller A and turbine A, form another active chamber by turbine B and pump impeller B, the active chamber of two symmetries by input shaft 4 and output shaft 18, be positioned in the rotating shaft of motor 26 and working machine 28; Adjust between pump impeller A and the turbine end clearance between turbine B and the pump impeller B; Between 3mm~6mm, the gap departure is less than 0.10/1000; And adjust the relative jerk value of external diameter, and its deviation should be come the parallelism and the coaxality of calibration motor and working machine central axis with this less than 0.12/1000, thus the fixed electrical machinery base.
With connecting cylinder 15, pump impeller A and shell 11 connect, and carry out the installation of box assembly again; Housing seat 3 is inserted on the swivel assembly that the school has installed, load onto bearing support 1, and input labyrinth bush 6, output labyrinth bush 19, proofread and correct housing seat 3, make its radial clearance identical, install oil inlet pipe 2 and conduit 10 again, through filler opening flange 161 and oil drain out flange 162, be connected with oil system 25 respectively with oil cooler 29; The case lid 12 that closes tights a bolt; Install input labyrinth bush 5 then, and output labyrinth bush 20.
At last.The oil circulating system assembly is installed.Wherein oil feed pump 22, oil cooler 29 is installed in the base plane that is lower than Coupler, (failing) oil pipe (line) of being correlated with in the connection, load onto the upper and lower water pipe of oil cooler, the oil pipe output terminal of oil cooler 29, receive the filler opening flange 161 of Coupler, and the oil drain out flange 162 of cooler oil pipe input end and Coupler joins, and links conduit 10 again.
The utility model hydraulic couplers is by the oily circulating load of regulation and control oil system, and the storage of the interior working oil of Coupler, regulates the rotating speed and the power of working machine.Therefore, 15 li flow control valve 212 is installed, solenoid directional control valve 211 and relief valve 213 are installed on (failing) oil pipe (road) at connecting cylinder.And the dexterity of action and the accuracy of inspection solenoid directional control valve.
When using the utility model hydraulic couplers, at first, start Oil pump electrical machinery 23 and oil feed pump 22, connect solenoid directional control valve 211,, treat that the rotating speed of Coupler output terminal increases toward (failing) oil pipe (road) fuel feeding, refuel by spells, until reaching the highest test-run a machine rotating speed that working machine 28 is allowed; Connect solenoid directional control valve 211, the working oil that makes (failing) oil pipe (road) is toward fuel tank (being positioned at outside the figure not expression in the accompanying drawing) lining oil extraction, and the rotating speed of output terminal decreases, and oil extraction by spells, until the minimum speed that working machine allowed.By connecting solenoid directional control valve, toward the oiling of (fail) oil pipe (road) lining, perhaps oil extraction in the fuel tank is to reach the purpose of adjusting active chamber internal memory oil mass during debugging.
The cyclic process of working oil is that oil feed pump 22 goes out the oil pump in the fuel tank after motor 26 starts, through flow control valve 212, regulate oil drain quantity, flow to oil circulating system, after oil cooler 29 coolings, through filler opening flange 161, arrive the oil inlet pipe 2 of Coupler, through oil-feed dish 7, enter in the pump impeller A, working oil obtains quickening in pump impeller, flows to the outer rim of turbine A by the outer rim of pump impeller A, promotes turbine A rotation; Fluid flows to inner edge from turbine A outer rim, and the liquid of fluid can be converted into mechanical energy, through output shaft output, drives working machine; Wherein a part of fluid, by the oil-through hole of turbine A, flow to turbine B, flow to pump impeller B through turbine B, pump impeller B similarly quickens fluid, makes it to obtain the liquid energy; Swiftly flowing working oil flows to the outer rim of turbine B by pump impeller B outer rim, promotes turbine B rotation; When fluid flows to inner edge by turbine B outer rim, its liquid can be converted into mechanical energy, through output shaft output, thereby realizes the transmission of power.After the working solution of turbine A, turbine B slows down, flow back to pump impeller A again, pump impeller B quickens, the liquid energy of reentrying, so circulation constantly.Central a part of working solution, by the gap between pump impeller A and the turbine A, and the flow control valve 212 in connecting cylinder 15 inner chambers is flowed out in the gap between pump impeller B and the turbine B, flow to catheter lumen 101, flow out from conduit 10, through oil drain out flange 162, (failing) oil pipe (road) flows to 29 li of oil coolers again, cool off, flow back into Coupler afterwards again, through filler opening flange 161, to oil inlet pipe 2.This cyclic process, the temperature that makes working oil enter Coupler is lower than 75 ℃, and should be lower than 90 ℃ from the oily temperature that Coupler comes out.The cooling water pressure of cooler should be greater than 0.2Mpa.
By in oil system, refueling, the work oil mass of swivel assembly is increased, carry-over moment just increases, and output speed improves; Otherwise when the past fuel tank oil extraction of oil system, the work oil mass reduces, and carry-over moment just reduces, and output speed decreases.Like this,, reach the control output speed by adjusting to the oil mass in oil system and the swivel assembly, its control accuracy height, the linear relationship of controlled quentity controlled variable and rotating speed is good.Working pressure in the oil system requires oil pressure greater than 0.05Mpa, and relief valve 213 is installed on the oil feed pump, and given its oil pressure relief is 0.63Mpa.The utility model hydraulic couplers is applicable to the hydraudynamic drive of high rotating speed, high-power, speed governing frequently.
