worm shaft

Both flanks of the worm shaft will now be coated with spotting color.

The worm shaft is mounted on two ballrace bearings.

This also had he advantage that it is easy to connect such boxes in series, using the rear end of the worm shaft as an output.

Mount worm shaft and wheel sequentially.

The wheel is mounted in its housing, but is still axially displaceable, i.e. transverse to the worm shaft axis.

This means we know exactly where the helical motor worm shaft is, and exactly where the burr drive shaft is.

This power steering gear uses a recirculating ball system in which steel balls act as rolling threads between the steering worm shaft and the rack piston.

In addition as duplex teeth are executed as involute gear they are insensitive in regards to modifications of the center distance, e.g. caused by worm shaft deflections.

Mines were moved by hydraulic worm shafts, the aft racks connecting directly to the launch tubes, which had vertically sliding hydraulic doors (rather than the usual hinged ones of torpedo tubes).
