FLEXIBLE SPINDLES
Flexible Spindle TypesSince the commercial development of gear type spindles in the early 1950's, their use has been universally accepted on all types of mill drives.

There are other factors which underline the importance of gear type spindles in mill drives. Ever increasing demands for higher rates of production necessarily result in increasing demands for higher speeds, higher torques, improved rolled - product quality, less maintenance and minimum downtime.

Ameridrives International patented the crowned gear tooth, and now offers Advanced Gear Design (patent pending). This optimized geometry crowned gear tooth increases capacities up to 300% greater than previous designs for high torque, high misalignment applications and longer life. Their constant angular velocity at misalignment angles ensures smooth power transmission, resulting in uniform size and improved surface quality of rolling mill products.

Styles

The SF Flanged Spindle is for medium duty, medium torque applications where relatively high misalignment capacity is required and where equipment is not subjected to frequent disconnection of drive components.

The SL Leveler Spindle is for medium duty, medium torque applications where relatively high misalignment capacity is required and where equipment is disconnected quickly and/or frequently.

The SM Mill Spindle is used on heavy-duty, high-torque applications requiring rugged strength such as metals rolling mill main drives and similar heavy equipment.

The VL Mill Spindle is used on medium to heavy duty metals rolling main drives and auxiliary equipment.
