Zero-Max Crown Gear drives provide directional motion change in all types of power transmission systems. They are right angle gear drives that operate quietly, are compact and sealed from contaminants. High class 10 spiral bevel gears and non-magnetic stainless steel shafts are features.
The Crown Gear drives were designed to cover the full spectrum of machine applications from packaging systems to food processing and material handling systems. They are suitable for a wide range of horsepower, torque and shaft speed requirements. Zero-Max offers the drives in standard two and three way models with 1:1 and 2:1 speed rations, shaft diameter combinations of 3/8, 1/2 and 5/8 and 3/4 inch.
The hardened class 10 spiral bevel gears are permanently mounted to the shafts with locking pins. The result is a durable connection for use in heavy load applications without maintenance.
Long-life precision hardened and ground ball bearings provide quite operation at speeds up to 2,000 rpm in most environments. The drives are pre-lubricated and completely enclosed in heavy-duty cast aluminum housings. The design ensures that internal gears remain permanently aligned, lubricated and free from outside debris contaminants.
Optional features include different shaft configurations, housing modifications for special mounting requirements and special finishes that include squared, splined, extended, shortened, stepped and combinations. Housing modifications include machining of special mounting flanges and mounting holes.
"Crown drives have been increasingly popular for use in automation systems because of their high quality, robust design and minimal backlash operation," says Robert Mainz, Zero-Max sales manager. "They easily handle reciprocating motion in most automated packaging machinery, paper converting, food processing and similar applications."
