Enhancing Operational Efficiency in Drum Rotation Systems in Asphalt Production Facilities
Climax Keyless Locking Assemblies provide an alternative method for assembling rotary trunnions in asphalt plants, replacing traditional sweat-fit techniques with a more serviceable and mechanically efficient solutions.
Asphalt production facilities utilize a series of trunnion assemblies to support and rotate drums containing heated asphalt mix. Traditionally, trunnion wheels are either machined from a single forged steel billet to exact dimensions or, more commonly, made using a “sweat fit” configuration. Using this “sweat fit” method, the axle is fitted between dual bearings and the mounted wheel, creating a rigid but maintenance-intensive assembly.
In the event of bearing failure or tire wear, the entire assembly requires disassembly for service. Due to the complexities of a sweat fit, separating the axle from the wheel is often difficult., necessitating elevated temperatures and the use of high-tonnage hydraulic presses, resulting in extended downtime and increased labor costs.
