Paramax® 9000 Series

Achievement of short lead time and high quality at the same time by combining components systematically

High gear tooth strength

Although the general gear has a pressure angle of 20 degrees, the gear for PARAMAX has 25 degrees. Larger pressure angle can secure thicker dedendum resulting in stronger gear tooth. This makes possible the design of a gear box with larger load capacity and higher impact load resistance.

Tooth profile of 9000 series (pressure angle of 25 degrees)

Tooth profile of general gear (pressure angle of 20 degrees)

Improvement in thermal capacity

Cooling effect is significantly improved with the adoption of a newly designed cooling fan and a cooling air duct cover. Improved thermal capacity can prevent deterioration of lubrication oil due to overheating of the reducer main unit, and the reducer can be used even under severe operation conditions including continuous operation with sufficient margin.
