A transmission or gearbox uses gear ratios so as to offer torque and speed conversions from one rotating power source to another. "Transmission" means the whole drive train which includes, prop shaft, gearbox, clutch, differential and final drive shafts. Transmissions are more frequently utilized in motor vehicles. The transmission alters the output of the internal combustion engine to be able to drive the wheels. These engines have to work at a high rate of rotational speed, something that is not right for stopping, starting or slower travel. The transmission increases torque in the process of decreasing the higher engine speed to the slower wheel speed. Transmissions are even utilized on fixed machines, pedal bikes and wherever rotational speed and rotational torque need change.

Single ratio transmissions exist, and they operate by altering the torque and speed of motor output. Lots of transmissions have several gear ratios and could switch between them as their speed changes. This gear switching can be carried out automatically or by hand. Reverse and forward, or directional control, can be supplied too.

The transmission in motor vehicles will generally connect to the engines crankshaft. The output travels through the driveshaft to one or more differentials in effect driving the wheels. A differential's most important purpose is to be able to alter the rotational direction, even though, it can likewise supply gear reduction too.

Power transmission torque converters and other hybrid configurations are other alternative instruments used for torque and speed alteration. Regular gear/belt transmissions are not the only machine existing.

The simplest of transmissions are simply called gearboxes and they supply gear reductions in conjunction with right angle change in the direction of the shaft. Every so often these simple gearboxes are utilized on PTO machines or powered agricultural machinery. The axial PTO shaft is at odds with the usual need for the powered shaft. This shaft is either vertical, or horizontally extending from one side of the implement to another, depending on the piece of machine. Snow blowers and silage choppers are examples of more complex machinery which have drives supplying output in many directions.

The kind of gearbox in a wind turbine is much more complicated and larger as opposed to the PTO gearboxes found in farm machinery. These gearboxes change the slow, high torque rotation of the turbine into the quicker rotation of the electrical generator. Weighing up to quite a few tons, and depending on the size of the turbine, these gearboxes normally have 3 stages to accomplish a whole gear ratio beginning from 40:1 to over 100:1. To be able to remain compact and so as to distribute the massive amount of torque of the turbine over more teeth of the low-speed shaft, the primary stage of the gearbox is typically a planetary gear. Endurance of these gearboxes has been a problem for some time.
