λ=f(i) curve for fluid couplings

SELECTION:
　　Without special requirements the following technical data sheet and power chart are used to select the proper size of fluid coupling with oil medium according to the power transmitted and the speed of motor,e,i,the input of the fluid coupling.
When ordering,please 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 notice the standard No.enforced).For ordering the fluid couplings with belt pulley,brake puley or othe special requirements please state the technical data in detail.

　　YOXz is a coincidence machine with moving wheel which is in the output point 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 even the axle-connecting machine designated by customers). Usually there are 3 connection types.

　　YOXz is inner wheel driver which has tight structure and the smallest axle size.The fittings of YOXz have 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 weak pillar and connected spiral bolt can unload the coincidence machine so 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 just for reference, the actual size is decided by customers.

Attention:
　　the smallest size Dp belt tray can do.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 directly inserts in the axle hole of the coincidence machine which is suitable in equipment 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 connected and has simple structure, the smallest axle size which 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 manufacture according to the sizes in the table.

　　YOXf is a type 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).
　　The relevant elastic axle connecting machine, connecting size and outer size is basically the same with YOXe type.
