KG Worm W2S L2-B Module 2.0 Pressure angle 20 degrees (straight teeth) S45C Precision rolled finish W2S L2-B 1 pc

Catalog number: W2S L2-B Features: ●Because it is processed by cold rolling, the surface of the thread is hardened by work hardening, and since the metal fiber structure is not cut, it has better mechanical properties than machine-cut worms. ●The surface hardness after rolling is 1.2 to 1.3 times the hardness of the base material, and the hardness of the thread surface is HB240 to 260. ●Since the surface roughness of the thread surface of a rolled worm is mirror-like, when used in combination with a worm wheel, the life of the worm gear is longer than when combined with a machined worm. Applications: ●Used in general industrial machinery, medical equipment, food machinery, etc. Specifications: ●Module: 2●Number of threads: 2●Reference circle diameter (mm): φ31●Hole diameter (mm): φ12●Shape: B●Tooth width (mm): 35●Total length (mm): 50●Tooth tip circle diameter (mm): φ35●Hub length (mm): 15●Hub outer diameter (mm): φ25●Lead angle: 7°25′●Twist direction: L●Worm twist direction and number of threads (mm): L2●Worm twist direction and number of threads: L2●Tooth shape: Straight teeth●Pressure angle: 20° Material/Finish: ●S45C carbon steel for machine construction Note: ●To obtain ideal meshing, accurately adjust the squareness when assembling the worm and worm wheel. ●Since the friction of the tooth surface at the meshing of the worm and worm wheel is large, please use it in a way that lubricates it as much as possible. ●Use a worm and a worm wheel with the same twist direction and the same number of threads. ● Design the worm shaft and worm wheel shaft to be sturdy and with bearings as close to the gears as possible to prevent bending. ● Please note that the axial thrust acting on the worm will be quite large. For information on axial thrust, please refer to the KG Gear Information in the general catalog.
