Grinding and Bending Vibration Method for Gear Couplings

Therefore, the outer teeth of the wheel hub are relatively short and drum shaped, while the inner gear ring is a relatively long straight tooth, which enables the coupling to compensate for the comprehensive displacement caused by various factors. When grinding teeth, apply the prepared abrasive to the teeth, evenly spread lubricating oil, and push the wheel hub to the position where the inner and outer gear rings will be stuck. Push the inner gear ring on the outer side of the wheel hub back and forth by hand, causing relative movement along the axis direction, and lubricating and running in under the action of abrasive. When grinding teeth, the force should be uniform, the movement should be kept horizontal, the speed of movement should be lower, and the running in time should not be too long each time to prevent overheating of the running in surface.

The bending vibration test of the gear coupling was conducted on a high-speed rotating steam turbine generator and air supply fan, and a brief explanation was given on the bending vibration caused by the gear coupling; Bending vibration tests were conducted on the shaft system of the gear coupling connection under different parameter conditions such as unbalance, lubrication conditions, clearance, error, and load; In addition, Shan Nei and Rangu et al. conducted a nonlinear analysis of the bending vibration of the half coupling system under the action of dry friction on the tooth surface. The vibration of the gear coupling is mainly related to the misalignment of the inner and outer gears and the friction of the tooth surface. Special attention should be paid to the lubrication of the tooth surface during high-speed rotation.
