Helical Gear Description Features: Improved Meshing Performance: Compared to spur gears, helical gears provide more complete meshing during transmission. This ensures stable gear transmission and a more consistent force distribution. Broad Compatibility: This helical gear is compatible with mini V1 or V2 extruders, Sherpa metal extruders, and other dual-gear extruders that fit the same dimensions. Long Service Life: With a large contact area and prolonged meshing time, the helical gear endures less stress. This enhances its load-bearing capacity and extends its lifespan. Compact Structure: The compact design of the helical gear allows for an effective deceleration effect with a smaller gear structure. Specification: For: Mini V1 or V2 extruders, Sherpa metal extruders, Sherpa extruders Package Size: 9x6x1 cm (3.5x2.3x0.4 in) Package Weight: 10 g (0.3 oz) Packing List: 1 x Helical Gear with hole 1 x Helical Gear without hole
