FILM PROJECTORS use a Geneva Drive for the stepwise transport of the film. The film drive is done for example with a so-called switching roller, which is seated on the cross shaft.

The press mechanism of a COFFEE BREWER for the compaction of the coffee powder is realized by a crank assembly. Here, a rotation is converted into a translatory motion.

The CHAIN DRIVE of a bicycle is a traction drive. Here, the torque is transferred to the output shaft of the rear wheel by the gears of the drive shaft, as a function of the gear ratio.

A DIFFERENTIAL MECHANISM in a motor vehicle rear axle is called axle differential and causes for the compensation of the rotational speeds between the two wheels.

The HUB GEAR is a mechanical transmission, which is installed in the rear wheel hub. Thereby, planetary transmissions are used. In this way, shifting systems from 2 to 14 gears can be realized.

In INTERNAL COMBUSTION ENGINES the reversed principle of a slider-crank mechanism is used. This causes the conversion of the rectilinear translation of the piston into a rotation of the crank shaft, and thus of the wheels.

In a VIDEO RECORDER various motion tasks can be realized. Often, combined gear designs are suitable for the realization of complex motions in need of minimum installation space.

A simple BARRIER DRIVE can be realized with a crank arm. Here, a rotating drive movement is converted into an oscillating output motion.

At a DESK LAMP two double cranks are connected in series with equal swing lengths and equal length of coupler and rack. This is a so-called parallel crank mechanism.

A MANUAL TRANSMISSION is the transmission in the drive train of a vehicle, which transmites the engine revolution to the drive revolution. Several gear sets allow different gear transmission ratios.

The STEERING GEAR OF A CAR is made of a worm gear. The power is transmitted from the steering wheel on the steering column to the steering gear, and from there to the steering rod on the steering levers on the steering knuckles.

In the INDEPENDENT WHEEL SUSPENSION of a car, the principle of the triangular control arm is used. The wheel suspension enables the suspension of the vehicle and allows steering, drive and braking movement.

The VALVE TIMING in an internal combustion engine consists of a planar cam mechanism and a subsequent mechanical linkage. Thus, the rotational movement is converted into a thrust movement.

In a DOOR LOCK different cam mechanisms and gearings are installed. These cause a conversion of the rotating movement of the key in a pushing motion of the bolt.
