Practical Lubrication of Open Gearing
Type 2 open gear drives typically consist of an actuator, pinion and a gear or a series of connecting gears used to transmit continuous loads. They are normally used to power stationary or semi-stationary equipment such as kilns, grinding mills, rotary furnaces, dryers, debarkers, rubber mills, paper mills and finishing mills.

Spiral Bevel and Hypoid Gear Cutting Technology Update
hobbed gears can also be finished by skiving. Grinding is not recommended for face-hobbed gears, as discussed later in the paper. Face hob cycle times are often faster than face milling due to the continuous indexing method, and face hobbing is always a complet-ing process. In face milling, one slot is cut at a time, Figure 1—Single indexing.

Grinding Mill Foundations
Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).

Basics of the Gear Milling or Gashing Process. With gashing, the gear wheel is held steady while a milling cutter advances axially along the face width of the gear blank. This process can be used to rough or semi-finish the tooth space with extra stock allowance for successive hobbing, grinding, shaving, or honing operations.
