Thermal Capacity of Helical Gearboxes in Continuous Operation

Buyer takeawayLosses leave the gearbox as heat, and allowable oil temperature depends on both the duty and the surroundings.No manufacturer-specific thermal rating, allowable oil temperature or cooling requirement is invented. Losses leave the gearbox as heat, and...

Choosing a Helical Gearbox Ratio for Variable-Speed Machines

Buyer takeawayA ratio has to serve the whole required output-speed range while the motor still produces safe torque and cooling.Examples describe motor and machine behavior generally; motor low-frequency limits require an actual manufacturer datasheet. A ratio has to...
