工程设计计算器
面向轴设计、螺栓连接、轴承、梁、齿轮和制造的专业级机械计算器。所有方法均可追溯至 ISO、ASME、VDI、DIN 和 AGMA 标准。
Beam Deflection Calculator
Determine the deflection, maximum bending moment, shear forces, bending stress, and support reactions for simply supported, cantilever, and fixed-fixed beams.
Key & Splines Shear Strength Calculator
Calculate shear strength of square/rectangular keys and involute splines per AGMA 2001 and DIN 3271 standards for keyed shaft connections.
AGMA 2001 Gear Strength Calculator
Calculate gear tooth bending strength (Lewis method) and surface pitting durability per AGMA 2001-B88 for spur and helical gears. Validates against ISO 6336 limits.
Shaft Diameter Calculator (Torsion)
Calculate required minimum shaft diameter under pure torsional loading for solid and hollow shafts.
Shaft Combined Bending & Torsion
Calculate required shaft diameter based on ASME B106.1M fatigue criteria combining bending and torsional moments.
Bearing L10 Fatigue Life
Determine rating life L10 in hours or revolutions for ball and roller bearings under constant radial loads.
Shaft Torsional Deflection & Stress
Calculate angle of twist, torsional shear stress, and polar moment of inertia for solid and hollow circular shafts under applied torque.
ISO 281 Bearing Dynamic Load Life Calculator
Calculate bearing dynamic load rating, equivalent load, and L10/Average life for ball and roller bearings per ISO 281:206. Includes relubrication life adjustment.
Engineering Unit Converter
