The term transmission refers to the whole drive train, along with the final drive shafts, differential, gearbox, prop shafts and clutch. Transmissions are more commonly utilized in vehicles. The transmission adapts the output of the internal combustion engine so as to drive the wheels. These engines should perform at a high rate of rotational speed, something that is not right for stopping, starting or slower travel. The transmission raises torque in the process of decreasing the higher engine speed to the slower wheel speed. Transmissions are also used on fixed equipment, pedal bikes and anywhere rotational torque and rotational speed require change.
There are single ratio transmissions which perform by changing the torque and speed of motor output. There are many various gear transmissions with the ability to shift amid ratios as their speed changes. This gear switching can be done automatically or by hand. Reverse and forward, or directional control, may be provided also.
In motor vehicles, the transmission is frequently connected to the crankshaft of the engine. The transmission output travels via the driveshaft to one or more differentials and this process drives the wheels. A differential's most important purpose is to be able to adjust the rotational direction, though, it can likewise provide gear reduction too.  
Power transmission torque converters and other hybrid configurations are other alternative instruments for speed and torque change. Standard gear/belt transmissions are not the only machine existing.
The simplest of transmissions are simply known as gearboxes and they provide gear reductions in conjunction with right angle change in the direction of the shaft. At times these simple gearboxes are utilized on PTO equipment or powered agricultural machinery. The axial PTO shaft is at odds with the common need for the powered shaft. This particular shaft is either vertical, or horizontally extending from one side of the implement to another, which depends on the piece of machinery. Snow blowers and silage choppers are examples of more complicated machines which have drives supplying output in several directions.
The type of gearbox in a wind turbine is a lot more complex and bigger compared to the PTO gearboxes found in farm machines. These gearboxes change the slow, high torque rotation of the turbine into the faster rotation of the electrical generator. Weighing up to several tons, and depending upon the size of the turbine, these gearboxes normally have 3 stages so as to achieve a whole gear ratio from 40:1 to more than 100:1. To be able to remain compact and so as to supply the massive amount of torque of the turbine over more teeth of the low-speed shaft, the first stage of the gearbox is usually a planetary gear. Endurance of these gearboxes has been an issue for some time.
