Document Summary
If have motor connected to machine and alignment is off = leads to excessive vibrations = more destructive = machine can fail. Depending on how alignment is, need to couple power source to gear reducer or machine the right way. Expensive and less flexibility for what gear reduction you have. More common is having power source separate from gear reducer. Use coupling to connect, couple shafts together, ensures transferring right amount of torque. Dif classes of how well aligned the shafts are. Dif couplings to use to make sure that torque transfer is there. For well aligned, want rigid coupling, bolted connections. Can use chain coupling gears on ends of shafts with chain that wraps around both sides to give some flexibility. Or use faulk, uses grid like mesh wire wrapped around both ends. Well aligned shafts but have temp variations use spline to ensure have good torque transfer but. Poor alignment allow shafts to slide on each other.
