I have a question regarding the inner hole of synchronous gears
Thread Content
The inner hole of a synchronizing gear can be either a cylindrical straight hole or a conical hole with a taper. May I ask everyone, in which situations is a cylindrical hole used, and in which situations is a conical hole used? Also, what are the differences between these two types of gears?
For cylindrical holes, a key is required to transmit torque, and the meshing position of the teeth cannot be adjusted； The keyless connection of the tapered hole allows for adjusting the rotation angle of the rotor (shaft).
So, aside from this difference, are there any other differences? For example, in terms of positioning and torque.
Tapered holes transmit more torque and provide more precise positioning.
