KG Geared Spiral Bevel Gear BG1.5S 20L30R-8H BG1.5S 20L30R-8H 1 pc

Catalog number: BG1.5S 20L30R-8H Features: ●Compared to gear cutting products, it can rotate at high speeds and is quieter. ●High strength specifications. After induction hardening of the teeth, the teeth are polished to a high precision. As a result, bending strength and tooth surface strength are improved by more than 20% compared to gear cutting products. ●Can be customized to high precision. The outer circumference of the hub and the outer circumference of the teeth are polished to maintain precision and ease of processing when additional processing is performed by the customer. (The outer circumference of the teeth is chamfered parallel to the axis, so it can be chucked with high precision.) ●Ideal for high-speed operation. ●Compared to gear cutting products, it can rotate at high speeds and is quieter. Applications: ●Used for general industrial machinery, high-speed rotating tool equipment, etc. Specifications: ●Module: 1.5●Number of teeth: 20●Reference circle diameter (mm): φ30●Assembly distance (mm): 37●Hole diameter (mm): φ8●Total length (mm): 22.49●Tooth width (mm): 9●Tooth tip circle diameter (mm): φ32●Hub outer diameter (mm): φ26●Hub length (mm): 14●Hole length (mm): 24●Tooth ratio: 1:1.5●Tooth tip angle: 31°21′●Gear precision: Tooth surface grinding finish●JIS B 1704 Class 1●Pressure angle: 20°●Twist angle 35°●Backlash amount can be set to 30μ or less Material/Finish: ●SCM440 (Chrome molybdenum steel) Note: ●Avoid meshing with gear cutting products or other products, and use only with our gear cutting products. ●For high-precision customization, be sure to use a raw jaw scroll chuck and reduce the runout of the hole surface of the product as close to zero as possible.
