HIGH SPEED GEARS-DESIGN AND APPLICATION by James R.

WebNov 9, 2024 · The involute form means that spur gears only produce radial forces (no axial forces), but the method of tooth meshing causes high stress on the gear teeth and high noise production. Because of this, spur gears are typically used for lower speed applications, although they can be used at almost any speed.

WebIf the wear expands until the tooth profile gets out of the shape, the gear can not be properly meshed anymore. Tooth surface fatigue occurs when the load is applied on the tooth surface repeatedly, or when the force is applied on the tooth is larger than endurance limit of the material. WebSep 22, 1974 · INTRODUCTION 1.I. THE EXCITATION FUNCTION The load on the teeth of a pair of gear wheels in mesh consists of a component corresponding to the transmitted power plus a fluctuating increment of dynamic origin. The excitation that produces the latter comes from within the system.
