KG worm W2S L1=C module 2.0 pressure angle 20 degrees (straight teeth) S45C precision rolled finish W2S L1=C 1 pc

Catalog number: W2S L1=C 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 grooves: 1●Reference circle diameter (mm): φ31●Hole diameter (mm): φ14●Shape: C●Tooth width (mm): 41●Total length (mm): 65●Tooth tip circle diameter (mm): φ35●Hub length (mm): 12 (lhR), 12 (lhL)●Hub outer diameter (mm): φ25●Key groove b2×t2: 5×2.3●Lead angle 3°42′●Twist direction: L●Worm twist direction and number of grooves (mm): L1●Worm twist direction and number of grooves: L1●Tooth shape: Straight teeth●Pressure angle: 20° Material/Finish: ●S45C carbon steel for machine construction Set contents/Accessories: ●Key material is included. Note: ●To obtain ideal meshing, be sure to accurately adjust the squareness when assembling the worm and worm wheel. ●Since there is a large amount of friction on the tooth surfaces when the worm and worm wheel mesh, we recommend that you operate the product in a lubricant whenever possible. ●Use a worm and worm wheel with the same twisting direction and number of threads. ●Design the worm shaft and worm wheel shaft to be sturdy, with bearings as close to the gears as possible to prevent bending. ●Please note that the axial thrust acting on the worm is quite large. For information on axial thrust, please refer to the KG Gear Information in the general catalog.
