The contact area map of the gear provides the drive and non-transmission surfaces of the drive gear, the driven gear, and the contact between the root and the top of the tooth, showing the maximum order, contact path and contact model.
In the contact area diagram of the gear, the same digital network is uneven on the tooth surface due to the change of the tooth depth coordinate of the action plane. The network line at the root is denser than the top, reflecting the undulations and irregularities, considering the actual test. Experience can be known: its contact point trajectory is slightly deviated from the direction of the tooth height, but the Wuxi vacuum pump does not produce diagonal contact; the contact trace itself is not curved enough to avoid the shape of bad spots such as fishtail.
However, since the direction of the tooth is biased to the ferrous sulfate of the water at the top of the tooth, the gear pair will be affected by the load concentration and must be paid enough attention. Therefore, the effective application of the contact curve map establishes the first safety line for the gear transmission quality.
In the specific application process, four sensitive elements are analyzed, that is, the tooth-shaped trimming amount in the tooth height direction, the drum shape in the tooth length direction, the pressure angle change and the helix angle change to seek the change of the gear pair. For example, the amount of drum shape in the direction of the tooth direction directly affects the contact length of the image. When the amount of drum shape becomes small, the contact pattern becomes longer, and vice versa.
By predicting these geometric characteristics, adjusting the design data, and fine-tuning the loaded state, satisfactory results can be obtained.
