Short Telescopic Universal Shaft

Short telescopic universal shaft is a power transmission device specifically designed for limited space conditions, which combines the angular compensation capability of the universal joint with the axial displacement compensation function of the telescopic joint. This composite transmission component performs well in working conditions that require simultaneous handling of axis offset and axial movement, and is widely used in automotive transmission systems, industrial machinery, marine propulsion systems, and aerospace fields.

Compared with traditional universal joints, the main features of short telescopic universal joints are their compact axial dimensions and unique telescopic structure design. Standard universal joints can usually only compensate for angular deviations, while short telescopic universal joints add axial displacement compensation capabilities ranging from ± 10mm to ± 50mm, and their overall length is longer than conventional ones; Universal shaft+sliding spline; The combination is shortened by 30% -50%.

Short telescopic universal couplings have been widely used in multiple fields due to their unique advantages:

1. Automotive industry:
   Connection between new energy vehicle motor and reducer (to solve axial displacement caused by motor pulse torque)
   Output shaft of four-wheel drive system transfer case (to compensate for body torsional deformation)
   Heavy truck transmission system (to adapt to chassis frame deformation)

2. Industrial equipment:
   CNC machine tool spindle coupling (compensating for thermal deformation displacement)
   Rolling mill universal joint shaft (bearing rolling impact load)
   Paper making machinery drying section (resistant to high temperature and humid environment)

As an important innovation in the field of precision transmission, the short telescopic cardan  shaft is constantly breaking through space limitations and performance boundaries through continuous technological progress, providing more efficient and reliable power transmission solutions for modern mechanical equipment.
