When designing a machine that needs to turn motion 90 degrees, engineers usually look at standard planetary gearheads or traditional worm reducers. Standard worm gears are great for high reduction ratios in tight spaces, but they come with two well-known headaches: backlash and friction. The DieQua Precision Worm (DPW) series takes a different approach. By using dual-pitch gear teeth and advanced metallurgy, it minimizes backlash without ruining tooth alignment or cutting into gear life. 1. How Dual-Pitch Teeth Control Backlash In a standard worm gear, the [...]
