The Z15 type expansion coupling sleeve is suitable for the occasions that require high rotation accuracy and transmit large loads. The inner and outer cone rings of the Z15 type expansion sleeve are tightened with hexagon socket bolts, the joint surface is longer, and the center is neutral.
The main purpose of the Z14 type expansion coupling sleeve (referred to as the expansion sleeve) is to replace the connection of single keys and splines to realize the connection of mechanical parts (such as gears, flywheels, belt pulleys, etc.) and shafts to transfer loads. Its function In use, it is divided into two categories: expansion and locking.
When the rated load of the Z13 expansion coupling sleeve is less than the load to be transferred, two or more expansion sleeves can be used in series, and the total rated load is: Mtn=m.Mt where: Mtn---n total rated expansion sleeves Load; m-load factor.
