Spojení kapalin

A fluid coupling nebo hydraulic coupling is a hydrodynamic or ‘hydrokinetic’ device used to transmit rotating mechanical power. It is employed in automotive transmissions in lieu of mechanical clutches. It is also used in industrial and marine machine drives in which it is possible to control the speed of operation and starting-up without shock loading of the transmission power system are vital.

Fluid Coupling Characteristics

-Improve the starting capability of the electric motor

-Protect the motor against overloading, damp shock, load fluctuation, and torsional vibration

-Balance and load distribution in case of multi-motor drives

YOXz YOXzⅡ YOXzⅢ Fluid Couplings Size and Specification

Fluid Drive CouplingYOXz je koincidenční stroj s pohyblivým kolem, které je ve výstupním bodě koincidenčního stroje a je spojeno s pružným osovým spojovacím strojem (pružný osový spojovací stroj typu švestkový květ nebo pružný sloupový osový spojovací stroj nebo dokonce osový spojovací stroj určený zákazníkem). Obvykle existují 3 typy připojení.
YOXz je ovladač vnitřního kola, který má těsnou strukturu a nejmenší velikost nápravy.Kování YOXz má široké využití, jednoduchou strukturu a jeho velikost je v podstatě sjednocena v obchodě.Styl připojení YOXz je, že velikost nápravy je delší, ale je zbytečné pohybovat elektromotorickým strojem a zpomalovacím strojem. Pouze vybouráním slabého pilíře a připojeným spirálovým šroubem lze vyložit náhodný stroj, takže je to extrémně pohodlné. Zákazník musí nabídnout velikost nápravy elektromotorického stroje (d1 L1) a nápravy zpomalovacího stroje (d2 L2). Velikost kola (Dz Lz C) v tabulce je pouze orientační, o skutečné velikosti rozhoduje zákazník.

YOXe YOXf Fluid Couplings Specification and Size

YOXf is a type of fluip coupling connected both sides, the axle size of which is longer. But it has simple structure and it is more easy and convenient for fixing and amending (unnecessary to move the electromotive machine and decelerating machine but only the elastic pillar and connecting spiral bolt can unload the coincidence machine).
Příslušný pružný spojovací stroj nápravy, velikost spojů a vnější velikost je v podstatě stejná jako u typu YOXe.

Fluid Couplings Advantages and Disadvantages

There are a variety of advantages and disadvantages to hydrodynamic fluid couplings may be discussed. One of them is that the fluid drive coupling could restrict the amount of torque that is transmitted through the motor. This is due to the fact that motors’ output torque the motor will be restricted when the output and input speed are the same.

Another advantage in fluid coupling is it can provide an absorption mechanism for shock of a mechanical nature. This is particularly important in situations where shock loads are encountered. For example, conveyors in mines carry many tons of materials each day. If the load gets excessively heavy, there will be an increase in wear and wear and tear on the drive assembly.

Another benefit for the use of a fluid coupling system is the fact that it gives soft starting. This helps reduce stress on the machine and also stop the coupling from cracking. The fluid coupling may be utilized to transfer the greatest torque that is possible.

The disadvantage for the fluid coupling is it could need more maintenance. This could include inspecting the fluid in the coupling and in the components. The manufacturer could also suggest altering the viscosity. The fluid used for a fluid coupling may differ according to the load, operating conditions, and also the casing of the fluid.
