These ultra compact low torque bevel gearboxes are designed to be lightweight and offer flexible mounting options through it’s ‘monobloc’ housing. This bevel gearbox is perhaps best described as a popular multi-purpose bevel gearbox that has been specified across a very broad range of applications. The 4 bolt hole design of the 2000 series provides improved mounting stability when compared to the 3 bolt hole design of the 4000 series.
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 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 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.
Close tolerance gear cutting and high accuracy assembly ensures extremely low operating noise levels, even at high running speeds.
Standard unit, final gear assembly, angular clearances are held to within 15’ - 30’ of arc.
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.
There are no special design features available for the Range-P bevel gearboxes. For a special design bevel gearbox please view the Neeter Drive Range-N. To discuss your requirments further please contact your nearest representative.
