Rosta Inc. is the Canadian affiliate of Rosta, which is reputed for offering world-leading tensioning technology for customers around the globe. This technology is the concept for manufacturing machine components for maintenance-free tensioning of chain drives and belts. This is why Rosta supplies five models of motor bases in its portfolio.
Motor bases are self-tensioning motor mounts that support suspension in friction belt drives. Rosta’s lineup provides major advantages over similar tensioning solutions from competitors.
Constant transmission of nominal torque
These components are two-in-one systems that have motor supports with integrated self-tensioning systems. Rosta motor bases create constant transmission of the nominal torque by maintaining optimal belt tensions. This operation results in three kinds of user savings:
Energy savings. Rigid motor suspensions should be inspected and belts should be re-tensioned on a regular basis. Rigid suspensions usually have an energy loss of roughly five per cent, as many belt drives can stand slip loss of only ten per cent before decreasing delivered torque. Since this energy loss accumulates in the long run, it can become expensive. Rosta designs its motor bases to provide consistent compensation of belt slip.
Maintenance cost savings. Rigid motor suspensions have time-consuming maintenance processes that include removing belt covers, checking tensions, aligning pulleys, adjusting motor position, and performing test runs. But these Rosta elements are maintenance-free, which saves time and money.
Transmissions-belt savings. Workplaces often use friction belt drives to drive large inertial masses, such as starting up 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 lives threefold.
In addition, Rosta motor bases can mount motors of up to 500 kilowatts, which is equal to 750 PS in power.
