Component Specifications

Definition
A mechanical adjustment system consisting of calibrated bolts and precision shims designed to fine-tune the position, angle, and contact pressure of scraper or plow blades in industrial machinery. This mechanism enables micron-level adjustments to optimize material removal, wear distribution, and operational efficiency while maintaining structural integrity under dynamic loads.
Working Principle
Utilizes threaded fasteners (bolts) to apply controlled displacement forces, combined with calibrated shims (thin spacers) to achieve precise dimensional adjustments. The bolt tension creates clamping force while shims provide fixed offset distances, allowing for repeatable positioning adjustments through mechanical interference and friction locking.
Materials
Bolts: Grade 8.8 or 10.9 steel with zinc plating or stainless steel A2/A4 for corrosive environments. Shims: Cold-rolled steel (CRS) 1008/1010, stainless steel 304/316, or brass C36000 for specific applications. Hardness: Bolts 22-32 HRC, shims 70-90 HRB.
Technical Parameters
  • Bolt Size M8-M16
  • Resolution 0.05mm per shim
  • Load Capacity 500-2000N per bolt
  • Shim Thickness 0.1mm-2.0mm
  • Adjustment Range ±5mm
  • Temperature Range -20°C to 150°C
  • Torque Specification 20-100 Nm
Standards
ISO 4014, ISO 4032, DIN 933, DIN 125

Frequently Asked Questions

How often should adjustment mechanisms be inspected?

Inspect every 500 operating hours or monthly, checking for bolt torque loss, shim wear, and corrosion. Critical applications may require weekly checks.

Can different material shims be mixed in one assembly?

No, mixing materials can cause galvanic corrosion and inconsistent compression. Use identical material shims throughout each adjustment point.

What lubrication is recommended for adjustment bolts?

Use anti-seize compound (copper or nickel-based) on threads to prevent galling and ensure consistent torque values during adjustments.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
