INTERNAL GEARS
B.I.R.S. Machine & Supply is a supplier of Internal Gears.
Internal gears are spur gears turned "inside out." The teeth are cut into the inside
diameter while the outside diameter is kept smooth. This design allows for the driving pinion to rotate internal to the gear, which, in turn, allows for clean operation. Internal gears are intended for light duty applications, these gears are available in many different materials. When choosing a mating spur gear, always remember that the difference in the number of teeth between the internal gear and pinion should not be less than 15 (14 1/2° PA) or 12 (20° PA).
