<p>The greater wheel rim is for the drive of a rotary or drum oven, diffuser or rod mill. The toothed surface (1) is of hardened metal, and is raised from the centre of the wheel base (2a). The wheel itself is 1.5 to 2 times as thick as the surface hardened layer. The wheel base also overhangs (2b) the hardened layer at each side by at least 1.5 times the tooth height. The narrow web (3) is connected to the central plane of the wheel base, and provides the driving connection. There are strengthening ribs (4) between the wheel base and the web.</p> |
