Classification
● Function: Mesh transmission, deceleration and torque increase, transmission of power and torque
● Material: 20CrMnTi/20CrMnMo/17CrNiMo6 alloy steel
● Process: carburizing and quenching+precision grinding of teeth, tooth surface hardness HRC 58-62
● Accuracy: Levels 5-7 (GB/T10095)
● Type:
○ helical gear (R/S/K/F series): smooth, low-noise, heavy-duty
○ Straight gear (ZQ/PM series): simple structure, suitable for old-fashioned reducers
○ Gear shaft (small gear+shaft integrated): high strength, high concentricity
Shaft (input shaft/output shaft/intermediate shaft)
● Function: Support gears, transmit torque, connect motors and working machines
● Material: 42CrMo/45 # steel, quenched and tempered treatment
● Structure:
○ Input shaft: connected to motor, high speed, medium low torque
○ Output shaft: connected to load, low speed, high torque
○ Intermediate shaft (gear shaft): multi-stage transmission, integrated gear+shaft
● Features: High bending strength, shear resistance, high-precision coaxiality
Bearings (support and wear reduction)
● Function: Support shaft and gear, reduce friction, ensure concentricity, and withstand radial/axial forces
● Common types:
○ Deep groove ball bearings (62xx/63xx): High speed, light medium load
○ Spherical roller bearing (222xx): Heavy load, impact, allowing for a small amount of centering deviation
○ Conical roller bearings (32xxx): withstand combined radial and axial loads
○ Needle roller bearings: compact space, large radial load
● Brands: SKF, FAG, NSK, HRB, ZW
Oil seal (double lip skeleton oil seal)
● Function: Leak proof, dustproof, sealed and lubricated
● Material:
○ Nitrile rubber (NBR): universal, oil resistant, -30 ℃~120 ℃
○ Fluororubber (FKM): resistant to high temperatures and chemical corrosion (180 ℃+)
● Structure: Double lips (main lip+secondary lip)+metal frame+spring
● Function:
○ Inside: Seal lubricating oil
○ Outer side: dustproof, waterproof, and prevent impurities from entering
● Common specifications: 30 × 45 × 10, 40 × 60 × 10, 50 × 70 × 12, 60 × 85 × 12, etc
● Function: Skeleton+Protection+Sealing+Heat Dissipation+Installation
● Material:
HT250 gray cast iron (universal type): shock-absorbing, easy to cast, low cost
○ QT500/QT600 ductile iron (heavy-duty type): higher strength, impact resistance
○ Cast steel (ultra heavy/mining): high strength, resistant to extreme working conditions
● Structure:
○ Split type (box cover+box seat): easy to assemble and maintain
○ Integrated: Good rigidity and high precision
