Shaft sinking - Wikipedia

The most visible feature of a traditionally-built mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist used, the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground). The headframe will also typically contain bins for storing ore being transferred to the processing facility. At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), w

A new mechanical system element representing a pulley-based differential transmission is proposed, which, when connected to a mass, is shown to simulate a capacitor in the general case. This new differential mass model provides an additional conceptual framework to model complex mechanical systems such as robotic manipulators.

Flat belt tracking on pulleys.

When the flat belt on such a pulley is off-center and the pulley rotating, the belt quickly moves up to the largest radius at the top of the crown and stays there. The crown is important to keep the belt "tracking" stable, preventing the belt from "walking off" the edge of the pulley. A crowned pulley eliminates the need for pulley flanges and ...
