gear box or speed reducer.
In worm gears, an axle or shafts has a screw that connects with another gear. This system is used when you need to change the direction of motion and reduce speed
A tread-wheel crane was a wooden lifting device that was used in Ancient Rome. The device had a large wooden wheel which was powered by workers when they used the pedals.
They used the idea of wheel hubsApex
A turbine.
Bevel gears can change the speed and motion and Worm gears can reduce speed and direction of motion.
it is used to change directions
a cannon
it is used to change directions
A crown gear has teeth that engage with other bevel gears. The teeth stick out at right angles to the face of the wheel. A worm gear is a screw that attaches to a wheel by engaging teeth along the wheel. As the screw turns, the wheel also moves and the drive reduces rotational speed and allows for higher torque. Worm gears are used when a project requires large gear reductions.
yes you can reverse worm and gear. A worm gear can rotate the worm, its based on the lead angle, pressure angle and co.efficient of friction between the pairs.
A bass guitar head.
It could be worn tie rod ends, if not then you need to check the steering box. The worm gear could be worn and you can adjust it with the nut on the steering box.
The early bird gets the worm. or you could use...The squeaky wheel gets the oil, The loudest dog get shot first, etc.
