The Design of YOX360 Constant filling fluid coupling
Abstract
This paper presents the design of YOX360 constant filling fluid coupling， including materials select , the design of parts of the product and the final a whole form, and shows in various parts of products with the map of CAD.
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.
When the power machine through the input shaft driven rotary pump wheel coupling, the cavity filled with the work of the working fluid and the impeller by centrifugal force to promote the dual role of the pump from the radius of the smaller round of pressure to accelerate the entrance was thrown round the radius of the larger pump exports, at the same time, the moment of momentum of liquid was incremental, that is, pump input power machine round to mechanical energy is transformed into kinetic energy of working liquid. When the work of kinetic energy with the liquid pump liquid into the round of exports across the turbine, the flow will be the impact of turbine blades to rotate in the same direction round pump, that is converted into liquid kinetic energy and mechanical energy to drive the turbine rotation and promote the work of the work machine. End of the liquid kinetic energy release of the work of the entrance of the flow of liquid from the turbine turbine pump export and re-enter the round of import, and start the next circulation. In this way, the working liquid in the pump and the turbine wheel of doing non-stop inter-cycle circulation spiral movement, the input shaft and output shaft in the absence of any mechanical connection, the liquid kinetic energy alone would be flexible to connect together.
