A drive is a system for transmitting power which sets machines and machine parts in motion (the term transmission is also often used).
In principle, the drive is the connection between the drive motor and the power-driven tool. Sometimes the tool requires the same speed, force and torque as the drive motor, but these can also differ from one another. We call this a variable transmission.
Within the mechanical power transmission, there are a number of ways to achieve transmission. These include V-belts, toothed belts, chains and shaft couplings.
With belt and chain drives, there are two parallel shafts onto which plates are mounted, which are connected to one another via an endless belt or chain. If the plates have the same diameter, they both rotate at the same speed; if the diameters are not the same then different speeds occur, which results in acceleration or deceleration of the drive.
Plates in this type of drive are available as standard in pre-drilled or taper bush versions (the latter is also known as a taper bus, taper lock or clamping sleeve).
If two shafts are in line with (or at an angle to) each other, shaft couplings can also be used to transmit power. These are available in different types: tyre couplings, elastic couplings, toothed couplings, fixed couplings, lamella couplings and cylindrical locking elements.
Mechanical transmissions are sometimes primarily used to transport products, rather than to transmit power. We call these internal transport drives, where the same type of transmissions are possible as for power transfer, but other requirements are placed on the products. Examples include friction properties or resistance to water and aggressive cleaning agents. Products in these drives are also often made of other materials, such as polyurethane (PU) or stainless steel.
