The Design of YOX500 Constant filling fluid coupling
Abstract
The fluid strength coupler is transmits the power using the liquid kinetic energy and the potential energy one kind of fluid drive equipment .Fluid coupling is essentially centrifugal pump and turbine combination. It mainly consists of the input shaft, output shaft, pump wheels, turbine, casings, auxiliary chamber and safety devices, etc. Input shaft connects with the power machine at one end and the other end with the pump wheel; turbine output shaft connects with turbine at one end and the other end connects with the work machine. Pump wheel and turbine layout symmetrical, round to set up a certain number of leaves. Pump wheel and casings fix into a sealed cavity, the cavity fills with liquid in order to transfer driving force for the work. The configuration Cyprus, such as the protection of explosive devices, is to ensure that coupling is not in overload, when the accident occurs. Limits the moment fluid strength coupler to be able to sharpen the prime mover starting capacity, starts the big inertia working machine steadily, the isolation vibration, relaxes the impact, the protection transmission system dynamic overload, is coordinated the load distributions between many prime movers, cannot modulate velocity and be separated from.
The fluid strength coupler has the following advantage :(1) Stepless speed regulation. In the electric motor rotational speed constant under may the stepless regulation working machine's rotational speed, compares with the traditional throttle adjustment may save the electrical energy massively. (2)The underloading or the idling starter motor and starts the big inertia load gradually, sharpens asynchronous machine's starting capacity) (3) The protection dynamic overload, between the coupler pump pulley and the turbine wheel does not have the machinery relation, the torque is passes fries in oil transmits, is one kind of flexibility and has the slippery difference transmission. When the load moment of resistance increases suddenly, its slippery difference may increase even applies the brake, the electrical machinery may continue to revolve does not send the parking. (4)Between even many electrical machinery's load sharing. When many motor-driven identical load, allows each electrical machinery's rotational speed to have the difference slightly, causes each electrical machinery's load sharing to be even. (5) May isolate the vibration, relaxes the impact. (6) May facilitate realizes the meeting and parting. The coupler flow channel oil charge is the joint, namely is separated from the oil evacuation (7) It not have the attrition besides the bearing, the work piece is reliable, the life is long. Therefore, in departments and so on metallurgy, electricity generation, mine, municipal engineering, chemical industry, transportation, spinning and weaving and light industry, obtained the widespread application.
