The Neeter Drive gearbox is an ultra compact unit and is available in 5 sizes and 5 gear ratios. The design employs a central bearing housing support on the 1:1 and 1.5:1 gear ratios, and a small extended bearing housing on the input side of the gearboxes with ratios 2:1 and above and hollow shaft output. It is a high torque rated unit with good thermal characteristics. It is available in solid shaft and hollow output shaft configurations and has the option of a motor mounting flange, for easy direct coupling of a standard electric motor.
General Design Features
S.G. Iron to BS27789:1985, Grade 420/12.
All gears are made from alloy steel and case hardened.
Pinion (input) and gear shaft (output) are fitted with twin taper roller bearings to provide almost unchanged backlash over a long life.
All units are fitted with spring energized single lipped oil seals and all flanges are sealed by O-rings.
Lubrication is dependent upon the operating conditions, oil for higher speeds and semi fluid grease for medium and low speeds.
Note: All units are shipped dry from the factory and should be lubricated before use.
Life of gears including mountings 10,000 hours.
Reduction ratio bevel gear units are approximately 95% - 98% efficient. Please consult Neeter Drive regarding increasing ratios.
All units are rated for in-line connection. If a unit is to be fitted with a belt pulley, chain sprocket etc., radial forces must be considered. If in doubt please consult Neeter Drive.
Note: Where operating conditions deviate from those described above please consult Neeter Drive.
