Features: The integrated shaftdesign ensures better concentricity of the gears, reduces eccentric rotation caused by assembly, and ensures more uniform transmission of finethreads. Hollow POMgear, reduction gear design, high transmission ratio, achieving greater extrusion torqueThe drivengear adopts doubleball bearings instead of original needle roller bearings, which have smaller clearances and high accuracy. The feedgear material is made of high-strength mold steel, and the surfaces treatments adopt NanoCoating. The overall hardness HRC value of the gear reaches 62-65; The surfaces hardness HV value reaches 1000-1200, greatly ensuring the strength, wear resistance, and corrosion resistance of the gear. Helical gear design, better meshing performances, smoother gear transmission, and more linear power transmission. The transmission overlap is large, the meshing time is long, and the contact area is large, which reduces stress, thereby improving the bearing capacity of the gear and extending its service life. Lightweight design ensures the strength of the gear itself while removing excess material on the gear, reducing its weight. Specifications: Name: NanoCoating Integrated Helical Gear Kit Processing Technology: POM Material: Polyformaldehyde and NanoCoated Mold Steel Scope of application: For Sherpamini extruders, for VORON V0, 0.1, and 0.2 series, or other places where this set of gears can be used. If you are good at mechanical design, you can also consider it as part of extruder design. Package Includes: 1Set NanoCoating OnePiece Helical Gear Kit note: Not applicable toBMG extruder Some productscan be equipped with forSherpa gears. Due to differences in dimensionsand tolerances, you can move the position by squeezing the black large gear or adding shims on the shaft to align the filaments inlet. Not applicable to all metalCNC forSherpa extruder
