Eliminate Unnecessary Dowtime in Asphalt Mixing Plants

Climax Keyless Locking Assemblies facilitate the repair and rebuild of rotary asphalt plant trunnion providing a cost effective and maintenance friendly alternative to the traditional sweat fit methods.

Asphalt plants incorporate the use of a series of trunnions for rotating drums containing hot asphalt mix. For years these trunnion wheels were manufactured from one piece of steel forged to the precise dimensions, or more commonly, an expensive and troublesome “sweat fit” assembly where the axle runs between two bearings and the mounted wheel. In the event of a bearing failure or tire replacement , an assembly repair is required. Most often disassembly of the axle from the wheel is extremely difficult and often impossible requiring the assistance of heat and high tonnage  presses.

The loss of productivity during this often lengthy downtime repair had management looking for a less demanding solution . Climax C405-series heavy duty keyless locking assemblies replicate the interference fit required for this application, allow for easy installation with simple hand tools, and most importantly, simplified disassembly and repair with the same hand tools when the need arises. With the use of a Climax C405 keyless locking assembly, replacement of a damaged shaft or wheel is not only possible , but efficient. Locking assemblies only required a straight bore through the wheel with easily obtained surface finishes and liberal tolerances . C405s installed between the shaft and the component bore are capable of transmitting the high torque, thrust and bending loads necessary for these applications .

Climax carries an extensive inventory of keyless locking devices with the capability to engineer custom designs to fit any application challenge.

For Rotating Applications:

• Keys, keyways, and set screws prone to shaft damage and keyway fretting

• Shrink or press fits that are difficult and costly to install and remove

• Requires the use of simple hand tools for installation and removal

• Tolerate tranmission of high torque, thrust, and bending loads
