Selecting the Right Gearbox

Bevel Gears

The GLEASON spiral bevel gears, of case-hardened alloy steel, provide an advancing, simultaneous mesh across several adjacent teeth, thereby ensuring smooth, evenly distributed, high load transmission, which is enhanced by, bi-directional, “running-in”, in pairs.

Shafts

Shafts are of case-hardened and ground alloy-steel. Exceptions are: both, the smallest casting sizes, types 2000 & 2002 and types 2012 & 2028, where shafts are all of hardened and temperated, low alloy-steel. All shafts are carried by generously sized, high quality, deep groove, ball bearings of established make.

Design Speed & Life

Optimum performance, at continuous full rated power transmission, is based on an input-shaft design-speed of 1400 RPM. This provides an average, trouble-free, operating design-life of 10,000 hours. However, where units are used as speed “increasers”, optimum performance, “input” design-speed is reduced to 500 RPM for the 3:1 ratios and, to 750 RPM for the 2:1 ratios. For all the types 4-way and 3-way independent shaft with a gear ratio difference of 1:1, the input shaft is the shaft A or C, where as the output shaft is B and D.

Operating Temperature

Operating case-temperature should be kept within the permissible limit of -18° C to +80°C (0°F to 170°F), to ensure trouble-free running.

Quiet Running

Close tolerance gear cutting and high accuracy assembly ensures extremely low operating noise levels, even at high running speeds.

Alignment Accuracy

Standard unit, final gear assembly, angular clearances are held to within 15’ - 30’ of arc.

Lubrication

All units are supplied fully charged with oil. The 2000 series is lubricated with synthetic oil. The lubrication is for life, they do not need replenishments or changes for all the lifetime of the gear.
