This set of high-quality helical steel sprockets features a 9_1 gear ratio in Dual Sector Gear (DSG) configuration. Unlike the standard 16 teeth per 1 cycle, these sprockets have two sets of 8 teeth on each side of the disc. This translates to two shots per full rotation of the disc. The helical sprockets are machined with precision CNC machines, resulting in improved performance, reduced noise, and lower power consumption. They also have reinforced gears and a better axis for increased durability. The oblique tooth arrangement of the helical gears results in quiet operation and smoother running, as well as more precise motion control thanks to the increased points of contact. These advantages make helical gears a preferred choice for mechanical and mechatronic systems.
