Abstract
There is a trend in the industry to make gears with a profile contact ratio greater than 2.0. The main reason is that these gears would run quieter by constantly having two or more teeth sharing the load. In order to obtain a profile contact ratio greater than 2.0, it is necessary to meet two requirements:
- 1.Have a fairly large number of teeth on each gear.
- 2.Have a low generating pressure angle of about 20° or lower.
Use of such gears, perform quieter than gears with a profile contact ratio that is greater than 1.0 but close to 1.0, where two teeth share the load only part of the time. These gears will be referred to as silent gears or low pressure angle gears. The disadvantage of these gears is that they have low horsepower capacity.
