Dec 21, 2006 · You can make gears with fewer teeth without undercutting on a 20 deg. gear than a 14-1/2 deg. gear. 2. 20 deg. gears require a closer tolerance on the gear-to-gear center distance to obtain the same backlash as 14-1/2 deg. gears. These are the two basic rules. So if you need small gears without undercutting the teeth, you need a larger pressure angle.

pressure angle gear_Gear Tooth Pressure angle - practicalmachinist.comOct 13, 2006 · A 20 degree pressure angle allows for a smaller gear with less teeth before they begin to undercut making the base thinner than the pitch circle thickness of the tooth. With a 14.5pa this begins to occur at around 25 teeth for an 18 dp gear but not until about 15 teeth for a 20pa gear.

There are other design considerations when changing to a higher-pressure angle.
pressure angle gear_Why is 14.5° a commonly used pressure angle in gears ...In gearing, according to Wikipedia and Dr. Rainer Hessmer's involute gear generator, the most popular pressure angles in the industry are 14.5°, 20° and 25°, with 20° being the most abundant. I can appreciate why 20° and 25° might be common values since they are nice round numbers.

pressure angle gear_List of gear nomenclature - WikipediaIn bevel gears, the shaft angle is the sum of the two pitch angles. In hypoid gears, the shaft angle is given when starting a design, and it does not have a fixed relation to the pitch angles and spiral angles.
pressure angle gear_Custom Spur GearsSpur Gears may be operated in a “gear-train” of two or more gears but they must all be of the same diametral pitch and pressure angle. Gears with 14-1/2° pressure angle will not operate with those cut to 20° pressure angle.
