Tooth Root Carrying Capacity


Tooth Root Carrying Capacity

For a successful application of new or modified construction elements component testing plays an important role. Tests under practical conditions as well as analogy tests provide the opportunity to determine the performance of components.
In order to determine the load carrying capacity or life span of gears, tests are carried out concerning surface durability and bending strength. Tooth root load carrying capacity is mainly influenced by the gear’s material, geometry, manufacturing method and parameters, assembly and operating conditions. WZL supports the following test rigs to determine the bending strength of gears:
Back-to-back test rigs providing real tooth contact are used to determine surface durability and bending strength. The load is applied to the test gear within a power circuit which can be opened and closed by a clutch. In contrast to back-to-back tests, the load of the test gear in pulsator tests is applied by an analogy process and not within a mesh. A single gear wheel is clamped between brackets and the applied force simulates the bending stress of the teeth.
The described tests have been and are conducted in many projects and represent one of the core competences of the gear department at WZL.
