Sometimes, we split teh gear on a plane perpendicular to its axis, and add torque to the system by using the two halves together with springs. Essentially, this system functions like a single gear with expanding teeth. We also taper teeth (in the axial direction), and allow the gear to slide in that same direction to fill the gap more easily.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

The traditional methods of backlash measurement include lead wire method and gap measurement method, 13 The backlash can be obtained by measuring the thickness of the thinnest part after the gear extrudes the lead wire or by measuring the data with a feeler gauge. The traditional method can get better precision in static measurement, and can be used as a reference for single backlash measurement.
