Due to the toothed drive, no weight preload is required for deflection. In the reversing wheel for System 65, the chain is deflected in a relaxed state. This results in reduced chain crawler tractive force. Less surface pressure in chain links leads to reduced wear.
The thrust ring of the reversing wheel for System 65 is made of GS material or has a welded structure; the hub cross is made of GG material or has a welded structure. The hub is drilled and grooved for perfect fit. Flanged wheel diameter with tread diameter up to 1010 = tread diameter + approx. 400 m; with tread diameter from 111 0 mm = tread diameter + approx. 500 mm.
Advantages of reversing wheel for system 65
• The bearing ring and the hub plate are stable welded constructions
• Weight-loaded initial tensioning is not required at the deflection due to the interlocked drive. The chain is redirected into uncompressed condition: reduction in wear
