High wear on worm & worm wheel
High wear on worm & worm wheel
(OP)
I am employing a worm & worm-wheel on application. It lifts and lowers a load, using an beam/arm.
The problem I am experiencing is a large amount of wear on the worm wheel and sometimes there is a vibrating whine when the load is beimng lowered. Could the load be overspeeding the motor?
One minute the gearset is quiet, then all of a sudden the noise appears.
Also I would like to know if anyone can recoomend a good worm and wheel grease
Thank-you for your time,
Regards.

To test this, can you turn somehow safely apply the load to the system without the motor connected to see if you can make the worm spin? If it does, then the load can overcome the drive.
The solution would then be to either create enough friction in the mesh to prevent backdrive (at the expense of wear and efficiency), or change out the gear and worm to a lower helix pair.
