description

This paver feeding tension shaft is made of high-quality alloy round steel, processed by turning, grinding, quenching and tempering, and surface hardening. It features high coaxiality and tight tolerance on shaft journals, with excellent wear resistance, bending resistance and fatigue resistance. As the spindle supporting the driven wheel, the shaft bears radial load under alternating chain tension and vibration impact. When adjusting the tension mechanism, the tension shaft moves together with the driven wheel to loosen or tighten the chain. If the shaft bends, the journal is scratched, grooved or the thread section slips, tension control will fail. The chain will be loose and tight alternately, greatly raising the risk of tooth jumping and chain breakage. As an original replacement spare part, it is often inspected and replaced together during feeding mechanism overhaul and chain renewal, indispensable for stable feeding transmission.

product parameters

- Name: Tension Shaft
- Applicable Model: XCMG RP705 medium crawler paver
- Material: Alloy structural steel
- Process: Precision turning, cylindrical grinding, quenching and tempering, surface hardening, anti-rust treatment
- Function: Support driven wheel, adjust chain tension, carry transmission load

Applicable Scenarios

Support and tension adjustment for driven wheels on left and right paver feeding mechanisms; tension calibration after chain elongation; replacement for bent shafts, worn journals and damaged threads.

advantage

- Precisely machined with good coaxiality for smooth and jam-free rotation of driven wheel
- Surface-hardened journal delivers long wear life and resists scratching
- Quenched and tempered substrate provides sufficient toughness against bending under impact
- Matches original tension support and driven wheel assembly for direct replacement
- Smooth adjustment and controllable tension reduce chain jumping and breakage

FAQ

Q: Can a slightly worn tension shaft be reused after grinding?
A: Grinding repair is not recommended. It will change the journal fit clearance, cause shaking and accelerate chain wear. New shaft replacement is preferred.

Q: What adjustments are required after installing a new tension shaft?
A: Mount the driven wheel and chain, adjust chain tension to factory specification, rotate the chain manually and check for jamming or unilateral friction.

Q: What symptoms appear if the tension shaft bends?
A: Chain deviation, failed tension adjustment and seized driven wheel. Localized overload will rapidly stretch or break the chain.

Q: Can tension shafts for left and right feeding sides be interchanged?
A: Interchange is allowed with identical part numbers. Pay attention to thread direction and positioning steps to avoid reversed mounting.
