Tooth surface design and analysis of pure rolling contact bevel gears based on preset transmission error
To address the problem that pure rolling bevel gears are prone to angular velocity mutation
vibration
and noise excitation under the influence of mounting errors
a tooth surface design method with low sensitivity to mounting errors was proposed.
Methods
2
Firstly
based on the influence of installation errors on angular velocity
the transmission error curve was preset as a parabolic type. Secondly
the theoretical tooth surface of the pinion was modified using the preset transmission error curve to establish a mathematical model of the target tooth surface. Finally
a 3D solid model of the modified bevel gear was constructed
and tooth contact analysis was performed.
Results
2
The results show that the derived transmission error curve is consistent with the preset curve
validating the effectiveness of the modification. The actual meshing points of the optimized tooth surface deviate from the edges
and the overall contact area centers on the tooth surface
effectively avoiding edge contact and stress concentration.
