description

This welded crank assembly is fabricated by welding high-grade alloy steel plates and forged shaft ends. Critical load-bearing welds are completed with multi-pass welding followed by stress relief to reduce residual stress and resist cracking under cyclic load. Machined shaft bores and lugs guarantee accurate center distance and concentricity for perfect fit with drive shafts and rod pins. After shot blasting, multi-layer protective coating is applied against hot asphalt, abrasive aggregate, muddy water and oil. Driven by the drive shaft, its eccentric geometry converts rotation into reciprocating movement for synchronized, smooth feed operation and reduces jamming and impact noise.

advantage

- Combined forged and welded construction provides high strength and fatigue resistance for cyclic impact
- Post-weld stress relief minimizes the risk of weld cracking
- Precision machined holes ensure easy fitting and synchronous transmission
- Durable protective coating resists corrosion and abrasion on construction sites
- Complete OEM welded assembly for direct drop-in replacement without on-site fabrication
- Accurate eccentric dimension keeps feed stroke within design specification

FAQ

Q: Can a crank with tiny weld cracks remain in service?
A: No. Cracks propagate rapidly under cyclic load and may lead to sudden fracture. Replace or perform professional repair and inspection immediately.

Q: Does a defective crank cause feed mechanism shaking?
A: Crank distortion, shifted eccentricity and weld cracks are common causes. Also check pins, bushings and drive shaft wear.

Q: What failures occur if the crank breaks?
A: The feed system stops. A sudden fracture may strike adjacent parts and cause secondary damage.

Q: Must connecting rod pins and bushings be replaced together?
A: Replace scored or excessively worn pins and bushings; undamaged ones may be reused.

Q: How to handle paint loss and rust?
A: Sand and recoat for light surface rust. Replace the assembly if rust penetrates welds or structural distortion appears.
