Let me introduce the characteristics of the bevel gear of the B3SH04 reducer in detail

The bevel gear (bevel gear) of the B3SH04 reducer is designed for medium-power industrial applications, and its core features are as follows:

1. Materials and heat treatment process

1. ‌High- strength alloy steel‌
   uses 20Cr2Ni4A carburized steel, with a depth of carburized layer of 1.2-1.6mm, a tooth surface hardness of HRC58-62, a core hardness HRC35-40, and a bending fatigue strength of 30% increased.

2. Surface strengthening technology
   The tooth surface is laser impact strengthened, and the residual compressive stress reaches -400MPa, and the fatigue life is extended by 2-3 times.

2. Structural design optimization

1‌. The helical angle error of tooth shape parameters‌‌0.1
° , the tooth direction deviation‌‌0.005mm/m, the meshing contact area‌ 90%, reducing bearing wear caused by axial force‌

2‌. The box seal
adopts a combination of maze seal + fluoroelastic oil seal, dustproof level IP66, adapts to the environment of dust concentration of 1000mg/m³

3. Working condition adaptability

1. Heavy load capacity‌Instantaneous
   overload torque reaches 1.3 times the rated value (lasting ≤10 minutes), adapted to the power range of 5.5-4400kW

2. Environmental protection
   gear non-meshing surface plated hard chrome (10-15μm) or PVD coating (TiN/TiCN), salt spray test ≥500 hours without rust‌

4. Maintenance and reliability

1. ‌Luxing system‌Recommended
   to use PAO synthetic oil (ISO VG320), with a flash point ≥240℃, and a high-temperature viscosity retention rate >90%

2. ‌Monitoring Design‌Built
   -in PT100 thermal resistance monitors oil temperature in real time, ≥80℃ triggers auxiliary heat dissipation, and ≥100℃ automatically reduces load

Note: As the basic model of B3SH series, its bevel gear design balances cost and performance, and is suitable for medium-negative mine conveyors, concrete mixers, etc.
