Basically, the rotational movement of the pinion is directly transmitted to the crown wheel
of the drum trough the gears.
Using a toothed crown wheel
to move its two lateral chain loops, the motor rotates the trays like a dumbwaiter.
Instead of a torque-sensing centre differential there's now one with a crown wheel
When a worm gear drive crown wheel
failed due to overload on a crucial conveyor belt at British Sugar's plant in King's Lynn, the priority was to get things running again quickly - and the ultimate result was a minimum of 10% improved efficiency.
5:1 reduction through a crown wheel
and pinion and a locked differential.
The Volvo compact excavator boasts a number of advances: boom offset to work alongside walls; two travel speeds; direct slewing crown wheel
drive; variable-width chassis; quick change attachment bracket for speedy job changes; control pattern selector for either excavator (ISO) or backhoe (SAE) operation; a tilting counterweight that provides both optimum machine protection and easy access the engine: and simultaneous digging and high speed operations for faster cycle times.
The crown wheel
and pinion center drive and the differential housing form an assembly that can be exchanged as a single unit.
The only brass parts he used were in the pendulum and its pivot and the crown wheel
The steel crown wheel
and worm screw transmission is lubricated with specialist oil to ensure reliable operation at low temperatures.
The axles include spur gear hub reduction, spiral bevel crown wheel
