GEAR MANUFACTURING
Manufacturing Industrial Gears & Overhauling Industrial Gearboxes.
The most common type of gears. The teeth on spur gears are 90 degree to the side, or face, of the gear. This requires that spur gears run parallel to one another. spur gears can be arranged in ling trains to meet required ratio reductions as well as maintained required size constructions.
The larger of two gears are typically called the gear, with the smaller one being a pinion
Any gear with the teeth at any angle other that 90degrees to the face of the gear the advantage of helical gears is an increased load capacity due to the extended face width over spur geards.
Helical geards may also be run at 90 degree to one another by using gears with the same helix angle.
Straight bevel gears and mitre gears can be manufacturered from 24DP to 3DP up to 20 inches in diameter and produced to meet AGMA class 8 levels.
These gears can be run in set and matched togather using our Gleasan motorized test machines assuring that the tooth contact bearing is correct with, and without laoding, backlash between mates is correct to the mounting distance, and that the noise level of the gear doesn't exceed maufacturing requirements.
When helical gears transmit motion between tow parallel shafts end thrust may be avoided by using herringbone gears. Herringbone gears are basically two helical gears placed side by side, with apposite hands of teeth.
