Z9 type expansion joint sleeve

Expansion sleeve model: Z9 type

Expansion sleeve surface treatment: light decoration, polishing

Expansion sleeve material: 45#,40Cr,304,430, etc.

Expansion sleeve use: link on the outer diameter of the wheel hub.

Expansion sleeve features: tightness, compact self-centering function; easy assembly and disassembly.

Usage: Combination and disassembly should be operated according to the usage method of the data page.When using, basically do not degrease.Degreasing may reduce the transmission torque, so special attention is required.It can be used in multiple stages, but must be combined according to regulations, such as confirming the strength of the wheel hub and strictly managing the connection torque.At the same time, the transmission torque is not doubled according to the combined quantity.Therefore, special attention is required.

Precautions for expansion sleeves: It is recommended to perform heat treatment such as quenching on the hub and shaft.Insufficient shaft strength results in reduced transmission torque, or the connecting ring is attached to the shaft and cannot be pulled out of the connection. After disassembly and reuse, pay attention to the deformation and lengthening of the bolt.When the bolt is deformed and becomes longer, it cannot be reused.New bolts need to be replaced.
