Component Specifications

Definition
The dancer roll mount is a precision-engineered mechanical component designed to securely hold and align dancer rolls within web handling machinery. It provides stable mounting points, allows for controlled movement of the dancer roll assembly, and ensures proper tension distribution across the web material. This component typically includes mounting brackets, adjustment mechanisms, and bearing interfaces to accommodate the dancer roll's oscillating motion while maintaining precise alignment with other web path components.
Working Principle
The dancer roll mount operates by providing a rigid yet adjustable framework that supports the dancer roll's weight and dynamic forces. It allows the dancer roll to move vertically or pivot in response to web tension variations, with the mount's structure absorbing mechanical stresses and maintaining alignment. The mount's design ensures smooth, low-friction movement of the dancer assembly while preventing lateral drift or misalignment that could affect tension control accuracy.
Materials
Typically manufactured from structural steel (ASTM A36 or equivalent), stainless steel (304 or 316 grade for corrosive environments), or aluminum alloy (6061-T6 for lightweight applications). Critical bearing surfaces may include bronze bushings or polymer liners for reduced friction.
Technical Parameters
  • Weight 15-150 kg depending on size
  • Load Capacity 500-5000 kg depending on application
  • Surface Finish Ra 3.2 μm or better for bearing surfaces
  • Adjustment Range ±50 mm vertical, ±5° angular
  • Mounting Pattern Standardized bolt circle diameters
Standards
ISO 9001, DIN 15061, ISO 2768-mK

Frequently Asked Questions

What is the primary function of a dancer roll mount?

The primary function is to provide stable, adjustable support for dancer rolls while allowing controlled movement in response to web tension variations, ensuring consistent tension control across the material web.

How does material selection affect dancer roll mount performance?

Material selection determines the mount's strength, weight, corrosion resistance, and friction characteristics. Steel offers high strength for heavy loads, aluminum reduces weight for high-speed applications, and stainless steel provides corrosion resistance in harsh environments.
