Description: Universal joint transmission component (Cardan shaft) for flat rotary fine screens within corn starch production lines. Installed between gear reducer motor and screen box; key power transmission spare for screening equipment. Composed of central splined shaft plus universal joint assemblies at both ends. It transfers rotary torque from gear reducer motor to screen box eccentric vibration mechanism, while accommodating angular misalignment and axial displacement between motor shaft and screen box input shaft, compensating assembly tolerances and positional shift caused by screen body vibration movement.
Intermediate splined shaft: Telescopic splined shaft providing axial expansion and contraction to compensate assembly distance errors.
Universal joint yokes: U shaped fork ends housing cross spider and shaft journals.
Cross spider: Cross form hinge component enabling angular offset torque transmission.
Needle roller bearings: Fitted on cross spider journals lowering friction and wear.
Connection flanges: End flanges coupling to motor output shaft and screen box input shaft respectively.
Bearing unit seals: Seals for universal joint bearing cavity blocking dust ingress.
Grease nipple: Lubrication port for periodic cross spider and spline set greasing.
Operates on universal joint hinge torque transmission principle.
1. Power input: Gear reducer motor output shaft drives one end of universal drive shaft via flange coupling.
2. Angular misalignment compensation: Dual end universal joints accommodate shaft angular offset while maintaining torque transfer even for non co axial mounting conditions.
3. Axial telescoping: Intermediate spline joint freely expands / contracts axially to absorb assembly distance error plus dynamic screen body positional shift.
4. Power output: Opposite shaft end drives screen box eccentric mechanism via flange to generate rotary vibration.
5. Continuous cyclic operation: Shaft rotates persistently, driving screen body planar rotary motion to complete screening workflows.
High transmission efficiency: Universal joint design delivers low torque loss and stable power transfer.
Angular compensation capability: Tolerates large angular offset between coupled shafts; reduces alignment precision requirements during installation.
Axial telescopic function: Spline joint absorbs assembly error and dynamic operational displacement.
Food grade material options: Stainless steel variants available, corrosion resistant, easy to clean.
Wear resistant construction: Cross spider plus needle roller bearings configuration offers long wear service life.
Dust tight sealing: Sealed construction prevents dust penetration into moving parts.
Service friendly: Periodic greasing maintenance only; individual worn components are replaceable.
