Power Transmission

Among the common mechanical machines that exist are:

• Inclined plane (wedge)
• Levers
• Gears
• Belts
• Wheels
• Cams
• Cranks
• Springs

These basic machines form the basis for all mechanical power transmission (PT) components.

Among the most common types produced by modern manufacturers are:

• Belt drives - a belt wrapped around two or more sheaves (pulleys)
• Chain drives - a chain wrapped around two or more sprockets
• Gear drives - one or more sets of gears in direct contact with each other

Bearing Service, Inc. is a stocking distributor of mechanical power transmission products. In addition to the above three types of drives are other components which are considered as part of the power transmission family of products:

• Couplings - used to connect two shafts together
• Clutches - allow rotation of a shaft in a single direction
• Brakes - stop the rotation of a shaft
• Reducers - enclosed gear boxes with one or more sets of gears
• Motors - the primary driver which causes PT components to rotate
• Tapered bushings - used to mount other PT components on shafts
• Torque limiters - overload safety devices'
• Tensioners - reduce slack on belt or chain drives
• Material handling - belt conveyors, screw conveyors and bucket elevators
