| Variable Speed Drives Hi-Ratio Series Overview | ||||||||||||||||||||||||||
| Lovejoy | ||||||||||||||||||||||||||
| Fixed Center Drives 1/3 through 3 HP Wide Variable Speed Belts In general, fixed center drives provide a greater total speed ratio than adjustable center drives. Traditional designs offer two pulleys of the same diameter, which means that a large portion of the driven speed range will be above motor speed. For those applications that require wide speed range and low driven speed, this has been a problem. Lovejoy's new Hi-Ratio system solves this problem by mating smaller driver and larger driven pulleys to provide the unique combination of broader driven speed ranges and lower minimum driven speeds. Features ■ Precision-balanced cast iron flanges for durability ■ No maintenance required, thanks to a unique self-lubricating bearing material used between sliding surfaces ■ Driven pulley springs are calibrated to maintain correct flange pressure against the belt ■ Minimum offset with the most common "C" mount configuration ■ Compact drive package because the driver and driven units are nearly in line with one another ■ Three drive packages available, ranging from 1/3 through 5 HP with a 1,750 RPM motor. Speed ratios up to 11.5:1 can be attained A motorized control feature is available for all three drive packages, making it possible to convert from the standard handwheel to convenient remote control. This option consists of a servo motor that opens and closes the driver pulley flanges from a separate control station, allowing accurate speed adjustment in locations that may be inconvenient, remote or hazardous. Conversion is easy, requiring only the removal of the handwheel and torque rod from the standard manual pulley, installing the motorized torque arm in place of the handwheel, and connecting the CN2601 control switch to the servo motor and power source. Every fixed center drive requires a torque arm bracket to prevent rotation of the handwheel so that it can be adjusted while the motor is running. Lovejoy offers a universally adaptable bracket, the Model 501. | ||||||||||||||||||||||||||
