This worm gear set works with a 6mm D-shaft as the input to the worm and the brass worm gear is able to fasten to an output shaft using a clamping or set screw hub. The 24mm center distance between the worm and the mating worm gear makes 1120 Series U-Channel the ideal structure to house this gear set in.
This gear set comes with the necessary hub and hardware to fasten both the pinion and the hub gear to 6mm D-shafting. The gears are constructed of zinc plated steel in order to hold up to extreme applications
This 20 tooth, MOD 0.8 gear will mate with any MOD 0.8 gear. However when building on pattern, the most common partner for this gear is a 100 tooth hub gear. This combo will create a 5:1 ratio, underdrive or overdrive depending on whether you’re set out to increase the speed or maximize torque.
This 30 tooth, MOD 0.8 gear will mate with any MOD 0.8 gear. However when building on pattern, the most common partners for this gear are another 30 tooth gear, or a 90 tooth hub gear. Utilizing a second 30 tooth gear will create a compact 1:1 ratio on a 24mm center distance. A 1:1 ratio is useful when you have an assembly where you want two pieces to move at the same time, but in opposite directions. Mating with a 90 tooth hub gear will create a 3:1 ratio on 48mm centers and can be used as an overdrive or underdrive.
This 12 tooth servo gear is most commonly used to drive the 108 tooth hub gear, spaced 48mm away, in order to create a massive 9:1 ratio. For a more compact setup, it will also mate with a 48 tooth hub gear, spaced 24mm away to create a 4:1 ratio.
