The worm and worm can not be rotated.



Problem: The worm wheel is made of dual-phase steel with high hardness. The worm 40Cr. is found to be unscrewed after assembly. The manufacturer said that the hardness is too high. I suspect assembly. I don't know the tall man.



Answer: worm wheel hardness should be lower than worm hardness. After assembling worm wheel and worm, check the following items.



After the above check, check the assembly clearance of the bearing. You can try it after loosening the end cap bolts on both sides.



Another way of saying is: excluding the lubrication problem, I think it is the accuracy of assembly.



The reason is that the internal resistance is greater than your input power. There should be two types of resistance here, the assembly accuracy produces similar to interference resistance; the turbine and worm itself resistance.



For the latter, the drive end is basically a labor-saving drive design, so the accuracy of assembly is mostly.
