I want to ask, if I want to connect a shaft from a motor that only has a diameter of 4 mm to a steel rod with a diameter of 30 mm, what should I do so that the motor can rotate the steel rod?
What that enormous size mismatch is telling me, is that likely there are other under- or overdesigns there somewhere. Could you please share more about that ... machinery?Steven123456789 said:a motor that only has a diameter of 4 mm to a steel rod with a diameter of 30 mm
2 bearings, ID 30 mm x OD 37 mm x width 4 mmBaluncore said:Welcome to PF.
How you couple the shafts will depend on how the 30 mm diameter bar is supported, on a frame by one or more bearings, of what type?
Is it balanced?
What is the maximum operating rpm of the motor and bar?
How is the motor mounted to the frame?
Can it self-align with the 30 mm bar?
Or must the coupling be flexible?
How much torque will the motor be providing?
Or what is the 30 mm bar being used for?
