WebPressure angle is the angle between the gear center line and a line perpendicular to the line of action. It defines the tooth profile. Generally, pressure angle value is kept at 20°, 25°, 22.5°or 14.5°. Higher pressure angle increases gear strength and reduces tooth tip interference. But they cause higher noise and bearing load. WebDec 21, 2024 · Construction of a cycloid. The shape of the flank of a cycloidal gear is a so-called cycloid. A cycloid is constructed by rolling a rolling circle on a base circle. A fixed point on the rolling circle describes the cycloid as a trajectory curve. A distinction can also be made between an epicycloid and a hypocycloid.
