Reverse Idler Wheels

Reverse Idler Wheels are designed for bucket elevators operating with LH chains and bucket attachments secured by pins and sidewalls. The wheels use exchangeable wear-resistant steel tread segments to support the chain. A welded steel hub is available with a raw or machined bore, keyway or preparation for a keyless clamping system. Catalogue models support LH chain sizes from 16 × 64 mm to 38 × 144 mm, with wheel diameters from 560 to 1550 mm. Other dimensions are available on request.

    • Introduction

    Reverse Idler Wheels guide and return LH chains at the non-driving end of a bucket elevator. They are suitable for systems in which pins and sidewalls connect the buckets to the chains.

    The chain rail uses exchangeable tread segments made from wear-resistant steel. The wheel and hub use welded steel construction.

    Hub configurations include:

       Raw bore;

       Machined bore according to customer requirements;

       Keyway;

       Machining for a keyless clamping system.

    The wheel incorporates guide discs that help control lateral chain movement. The guide disc diameter De corresponds to the chain rail diameter plus:

       Approximately 400 mm for wheel diameter D up to 980 mm;

       Approximately 500 mm for wheel diameter D up to 1280 mm.
