How to choose the suitable B3SH06-12.5-A reducer bevel gear

The bevel gears of B3SH06-12.5-A reducer need to comprehensively consider material characteristics, transmission parameters and working conditions. The following are the key points:

1. Materials and heat treatment requirements

1. ‌Alloy steel material‌20Cr2Ni4A carburized steel
   is recommended , the tooth surface hardness must reach HRC58-62, and the core hardness HRC35-40 to ensure the bending fatigue strength is increased by 30%

2. Surface treatment process‌Laser impact enhancement treatment can form -400MPa residual compressive stress layer, with a fatigue life of 2-3
   times , suitable for high impact load scenarios‌

2. Transmission parameter matching

1. Speed ​​ratio and torque adaptation‌ The speed ratio of
the B3SH series is 5-400, and the transmission ratio needs to be calculated based on the motor output speed and load requirements. For example, when the 1500r/min motor drives a 30r/min load, the model with a speed ratio of 50 should be selected‌

2. Multi-stage transmission distribution
‌High reduction ratio requirements (such as i>100) It is recommended to use multi-stage transmission, and the transmission ratios at each level are allocated according to the principle of 'small front and large rear' to balance the gear load and lubrication effect.

3. Mechanical interface design

1. ‌shaft system connection ‌the tolerance of
   the input shaft and motor shaft diameter must be controlled within ±0.01mm. ISO standard flat key or involute spline is recommended, and torque transmission efficiency is ≥98%

2. Installation method:
   Horizontal installation requires the coaxial error of ≤0.05mm/100mm. Vertical installation requires the configuration of double-lip sealing ring and axial load bearing.

4. Working condition adaptability

1. Environmental protection‌Not
   - engaged surfaces are recommended to plating hard chrome (10-15μm) or PVD coating (TiN/TiCN), salt spray test is ≥500 hours without rust‌

2. ‌Luction and Heat Dissipation‌Recommended
   PAO synthetic oil (ISO VG320), built-in PT100 thermal resistance to monitor oil temperature, triggering auxiliary heat dissipation‌

5. Special scenarios Selection suggestions

• Heavy-load application : Instantaneous overload torque must be ≥1.3 times the rated value (lasting ≤10 minutes), adapted to the power range of 5.5-4400kW

• ‌Dust Environment‌ : Select IP66 sealing level, the combination of labyrinth seal + fluoroelastic oil seal can adapt to 1000mg/m³ dust concentration‌
