Maysville, Ky. – STOBER™ Drives, Inc. has developed a new KL helical bevel gear unit, a compact right-angle drive that meets the packaging manufacturing industry’s latest machine requirements. The space-saving gear reducer comes in sizes 1 and 2, and is perfect for packaging, filling, conveying, general automation and wash-down.
When compared with the conventional STOBER K1 helical bevel gear unit version, the new KL1 supplies increased torque density of well over 100 percent. The size reduction for the KL was achieved by a newly designed, 2-stage gear set geometry. The housing dimensions of the two sizes illustrate the new shape factor. In the KL1 version, the length is 113.5 mm, the width 81mm and the depth 90 mm; this represents a volume of only 0.83 liters.
The KL2 is 143.5 mm long, 98 mm wide and 108 mm deep, which makes its volume only 1.52 liters. This compact housing also gives a significant weight reduction, which is an advantage for drive dynamics, particularly on traveling axes.
Input speeds of up to 6,000 rpm are possible in cyclic operation with a torque range up to 65 Nm. The highly stiff, compact and symmetrical design requires no offset because the unit looks virtually the same on either side. On the output side, the new right-angle gear unit offers various options for output shafts and mounting methods, including solid shafts with and without keys, and hollow output shafts with and without keys. Output shafts are available in carbon and stainless steel.
Motors from other suppliers can be fitted using an adapter with a backlash-free coupling that features thermal length compensation. Both sizes are available in all the different versions.
