Motorbase units by Rosta support suspension in friction belt drives

Five models of Rosta motorbases are available.

Rosta Inc. is the Canadian affiliate of Rosta, known for providing the best in tensioning technology for businesses around the world. This technology is the concept for manufacturing machine components for maintenance-free tensioning of chain drives and belts. This is why Rosta offers five types of motorbases in its portfolio. Motorbase units are self-tensioning motor mounts that support suspension in friction belt drives. Rosta’s lineup offers key benefits over competitors’ similar products.

Three kinds of savings

These elements are two-in-one systems that have motor supports that have motor supports with integrated self-tensioning systems. Rosta motorbases create constant transmission of the nominal torque by maintaining optimal belt tension. There are three kinds of savings resulting from this operation:

• Energy savings – Users should inspect rigid motor suspensions and re-tension their belts on a regular basis. Rigid suspensions typically have an energy loss of about five per cent, since many belt drives can stand slip loss of only ten per cent before decreasing delivered torque. As this energy loss accumulates over the long term, it can become costly. Rosta makes its motorbase units to deliver consistent compensation of belt slip.
• Maintenance cost savings – Rigid motor suspensions have time-consuming maintenance processes that include removing belt covers, checking tension, aligning pulleys, adjusting motor position, and performing test runs. But these Rosta elements are maintenance-free, which saves money and time.
• Transmission-belt savings – Workplaces frequently use friction belt drives to drive large inertial masses, like starting up large flywheels for saws, pumps, presses, or stamping equipment. Other motor suspensions result in excessive stretch and early wear in seat belts. But Rosta mounts deflect slightly at startup and then swivel back to normal working positions when mass rotation is stable. Treating belts more gently can extend their operational lifespans threefold.

Rosta motorbase units can also mount motors of up to 500 kilowatts – equal to 750 PS in power.
