A liquid coupling or hydraulic coupling is a hydrodynamic or ‘hydrokinetic’ device used to transmit rotating mechanical power. It’s been found in automobile transmissions as an alternative to a mechanical clutch. It also has widespread application in marine and commercial machine drives, where variable speed operation and managed start-up without shock loading of the energy transmission system is essential.
Features:
Improve the starting capability of electric motor, protect electric motor against overloading, damp shock, load fluctuation and torsional vibration, and balance and load distribution in the event of multimotor drives.
Applications:
Belt conveyers, csraper conveyers, and conveyers of most types Bucket elevators, ball mills, hoisters, crushers, excavators, mixers, straighteners, cranes, etc.
SELECTION:
Without special requirements the following technical data sheet and power chart are accustomed to choose the proper size of fluid coupling with oil medium based on the power transmitted and the quickness of engine,e,i,the input of the fluid coupling.
When ordering,make sure you specify the dimensions of the shaft ends of lmotor and driven machine(or reducer)including diamenter,tolerance or fit of the shafts(if no tolerance or fit is specified,the bores will be machined th H7),fit length of the shafts,width and depth of the keys (of spot the standard Simply no.enforced).For ordering the fluid couplings with belt pulley,brake puley or othe unique requirements please state the technical data in detail.
YOXz is a coincidence machine with moving wheel which is in the output stage of the coincidence machine and is connected with elastic axle connecting machine (plum blossom type elastic axle connecting machine or elastic pillar axle-connecting machine or actually the axle-connecting machine designated by customers). Usually there are 3 connection types.
YOXz is inner wheel driver which includes tight framework and 
the smallest axle size.The fittings of YOXz have got a wide usage, simple structure and the size of it has basically be unified in the trade.The connection style of YOXz is that the axle size of it is longer but it is unnecessary to move the electromotive machine and decelerating machine. Only demolish the poor pillar and linked spiral bolt can unload the coincidence machine so that it is extreme convenient. Customer must offer the size of electromotive machine axle (d1 L1) and decelerating machine axle (d2 L2). The wheel size (Dz Lz C) in the table is merely for reference, the actual size is set by customers.
Attention:
the tiniest size Dp belt tray can perform.the largeat size the dl axle hole can doYOXp type is a connection style of belt tray with hydraulic coincidence machine. The electromotive machine (or decelerating machine) axle straight inserts in the axle hole of the coincidence machine which would work in tools transported by belt.Customer must supply the connection size of electromotive machine axle (d1 L1) and the detailed specification and size of belt tray.
YOXm is one that the axle of decelerating machine directly inserts in the axle hole of coincidence machine and the electromotive machine point ML(GB5272-85) connects with plum blossom type elastic axle connecting machine. It is reliable linked and has simple structure, the smallest axle size which really is a common connection type in current small coincidence machine.
Customer must supply the size of electromotive machine axle (d1 L1) and decerating machine axle (d2 L2) as shown in the picture, others if customer do not supply, we will produce according to the sizes in the desk.
