Component Specifications

Definition
The Ring Body is the primary structural component of a Trunnion Ring assembly, designed to support and facilitate the rotation of large cylindrical loads in industrial applications such as kilns, mills, and rotary dryers. It is engineered to withstand significant radial and axial loads while maintaining precise alignment and minimal friction through integrated bearing surfaces. The component typically features mounting interfaces for rollers or bearings, lubrication channels, and attachment points for ancillary equipment.
Working Principle
The Ring Body operates on the principle of distributed load support through a continuous circular structure. It transfers weight from the rotating drum to stationary support rollers via precisely machined raceways, minimizing point loading and ensuring smooth rotation. The geometric design optimizes stress distribution to prevent deformation under operational loads.
Materials
Forged or cast steel (typically ASTM A36, A572 Grade 50, or equivalent alloy steels), with surface hardness of 200-300 HB for wear resistance. Optional coatings include flame-sprayed ceramics or hard chrome plating for abrasive environments.
