KG Worm W1.5SU R1-B Module 1.5 Pressure angle 20 degrees (straight teeth) S45C Precision rolled finish W1.5SU R1-B 1 pc

Catalog number: W1.5SU R1-B Features: ●The worm has a precision rolled finish. ●Module 0.5, 0.8, 1.0, pressure angle 20° (straight teeth). ●Since the surface roughness of the threaded 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: 1.5●Number of threads: 1●Reference circle diameter (mm): φ25●Hole diameter (mm): φ10●Shape: B●Tooth width (mm): 30●Total length (mm): 43●Tooth tip circle diameter (mm): φ28●Hub length (mm): 13●Hub outer diameter (mm): φ20●Lead angle 3°26′●Worm twist direction and number of threads: R1●Twist direction: R●Worm twist direction and number of threads (mm): R1●Tooth shape: Straight teeth●Pressure angle: 20° Material/Finish: ●Stainless steel (SUS304) Note: ●To obtain ideal meshing, accurately adjust the squareness when assembling the worm and worm wheel. ●Since the friction of the tooth surface is large when the worm and worm wheel mesh, 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.
