Telescopic Cardan Shafts
A telescopic cardan shaft is a mechanical transmission device that combines cardan shafts and telescopic functions, capable of transmitting power in the presence of angular displacement and axial displacement between shafts. This device is widely used in transmission systems that require compensation for axial displacement and angular deviation.
The telescopic cardan shaft mainly consists of the following key components:
cardan shaft section: usually adopts a cross axis or ball cage structure, allowing for a certain degree of angular deviation between the two axes
Expansion slide sleeve: achieves axial expansion and contraction function through spline or groove structure
Sealing system: prevent lubricant leakage and contamination from entering
Lubrication device: Ensure smooth operation of all moving parts
The working principle is based on two independent but collaborative functions: the cardan shaft compensates for angular deviation, and the telescopic mechanism compensates for axial displacement. The combination of the two enables the transmission system to adapt to complex working conditions.
