An experimental method to measure gear tooth stiffness throughout and beyond the path of contact
نویسنده
چکیده
A method is presented that allows the accurate measurement of the tooth pair stiVness of a pair of spur gears. The method reveals the stiVness behaviour throughout the full length of the normal path of contact and also into the extended contact region when tooth corner contact occurs. The method makes use of the properties of transmission error plots for mean and alternating components over a range of tooth loads (Harris maps). It avoids the usual problem when measuring tooth de ̄ections that de ̄ections of other test rig components are diYcult to eliminate. Also included are predicted Harris maps for a pair of high contact ratio spur gears, showing the eVects of various simplifying assumptions, together with a measured map.

Predicting Depth and Path of Subsurface Crack Propagation at Gear Tooth Flank under Cyclic Contact Loading
In this paper, a two-dimensional computational model is proposed for predicting the initiation position and propagation path of subsurface crack of spur gear tooth flank. In order to simulate the contact of teeth, an equivalent model of two contacting cylinders is used. The problem is assumed to be under linear elastic fracture mechanic conditions and finite element method is used for numerical...

The surface tooth wear which occurs at the gear contact region due to inadequate contact strength of the tooth is one of the predominant modes of gear failures. Currently, higher contact ratio spur gears are increasingly used in power transmission applications such as aircraft, wind turbine, automobiles and compact tracked vehicles due to their high load carrying capacity. In this work, the di...

متن کاملInfluence of Addendum Modification Factor on Root Stresses in Normal Contact Ratio Asymmetric Spur Gears
Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...
