B-Series bevel helical gearbox - right angle heavy duty

Capability Highlights

2 to 4 gear stages delivering right-angle power transmission
Gleason spiral bevel input stage for high efficiency and low noise
Flender B-Series exact dimensional and performance interchange
Heavy cast iron or fabricated steel housings for shock resistance

Typical Applications

Cement rotary kilns and crushers
Port crane hoists and travel drives
Water treatment aerators and clarifiers
Right-angle heavy belt conveyors

Engineering Focus

Right-angle mounting footprint and shaft alignment
Bevel gear meshing accuracy and noise levels under load
Overhung load (OHL) limits on the output shaft
Labyrinth sealing for harsh, dusty, or wet environments

Key Evaluation Matrix

Metric	Typical Range	Why It Matters
Nominal Torque Range	3,600 to 1,400,000 Nm	Right-angle drives must handle the same immense torque as parallel units but often in tighter footprints.
Ratio Range	i = 5 to 400	Versatile reduction capabilities for heavy-duty process machinery.

RFQ Checklist

Provide incumbent model code (e.g., Flender B3SH11)
Specify mounting orientation (horizontal, vertical, upright)
Define cooling requirements (fan, internal coil, external system)
Include 2D/3D installation envelope drawings

Risk Controls

Bevel gear failure under shock load: We utilize premium case-hardened alloy steels and hard-finishing (lapping/grinding) for the bevel stage.
Oil leakage in vertical shaft installations: Vertical units feature dry-well construction and specialized double-lip or labyrinth sealing systems.
