Motion system designers looking for a smooth operating, quiet right angle gear drive might consider Zero-Max Crown gear drives. They feature heat treated AGMA Class 10 spiral bevel gears and non-magnetic stainless steel shafts providing long term, maintenance free operation. Zero-Max Crown gear drives feature long-life, precision hardened and ground ball bearings handling speeds up to 2,000 rpm in most operating environments. The internal gears are permanently mounted to the shafts with locking pins. This provides a very resilient and durable connection for use in heavy load applications while requiring no maintenance.
Zero-Max ensures their drives are predictably smooth operating, and similar model sizes have identical performance characteristics when designed into multiple drive setups. To accomplish this, Zero-Max drives are hand-shimmed and hand-assembled for perfect bearing and gear alignment. The drives are pre-lubricated during assembly, then completely enclosed in a heavy-duty anodized aluminum housing. This design ensures that internal gears stay permanently aligned, lubricated and free of contamination from outside debris. Zero-Max Crown drives are suitable for a wide range of machine applications including food processing, packaging and material handling systems. Standard two and three way models are available with 1:1 and 2:1 speed ratios in shaft diameter combinations of 3/8, 1/2, 5/8 and 3/4 inch.
"System designers increasingly prefer gear drives that operate quietly without maintenance requirements," reports Robert Mainz, Zero-Max sales manager. "Crown drives fulfill those requirements. They have become a preferred choice for automated systems because of their robust design and quiet operation."
