It is a worm gear with shafts perpendicular to each other. It consists of a helical worm screw and a circular cogwheel. Some applications of this device are automatic doors or elevators systems, where motion in one direction and blocking the...

It is a mitre gear. It is made up of bevel gears that consist of two conical cogwheels. This device is used to transmit motion between two perpendicular shafts.

It is a spur gear. This type of gear is the simplest one, normally used for low or medium speeds, since they are noisy if not well-formed.

It is a two-stage spur gear. Two-stage gears are used when rotation transmission between shafts cannot be obtained with only one pair of gears.

It is a variable speed belt drive. Continuously variable gearboxes are the ideal transmission since they change the speed ratio continuously. For that reason they are considered an automatic transmission with infinite number of ratios. Variable...

It is a control gear. Its function is to control the space between teeth.

It is a multiple-disk clutch. Multiple-disk clutches allow for transmitting higher torques. Such clutches are used in the steering of chain tractors.

It is a pedestal bearing. Bearings are commonly used in industry, their function is to withstand a load while in contact with other body, having relative movement between them.
