How do you determine the wheel width of a gear? Is there a table to check? Do you have an empirical formula or something?
First, the width of the tooth is determined according to the coefficient of width of teeth. Generally speaking, the width of the wheel is wider than the width of the tooth. But you need to pay attention to the connection of wheel hub and gear. If the wheel hub and gear are interference fit, then the length of the wheel hub is determined according to the force transmission requirement under interference fit. If the wheel hub and gear are connected, pay attention to the strength of the key used by the wheel hub and the gear to transfer the force, and the strength of the key is related to the length of the key. Then you can completely determine the length of the wheel
Please refer to the mechanical design manual, the third chapter of the gear drive chapter. Also, in some of the 3D design software gear plug-in, there are recommended values, you can refer to.
There is no strict rule for the width of the gear wheel, and there is no direct formula for the width of the gear. It is related to the load and the working conditions. There is also a recommended value
