This page explains how Gear Housing is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The protective enclosure that houses and supports the gears, bearings, and other components of a main drive gearbox.
Technical details and manufacturing context for Gear Housing
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Torque | 500–5000 N·m | Determines gearbox size and material selection.ISO 6336 |
| Gear Ratio | 5–100 | Customizable per application. |
| Input Speed | 500–3000 rpm | Higher speeds require better lubrication and cooling. |
| Operating Temperature | -20–80 °C | Outside range may affect seal integrity and lubricant viscosity. |
| Ingress Protection | IP54–IP65 | Higher IP for dusty or wet environments.IEC 60529 |
| Material Grade | HT250–QT450 | Cast iron for cost, ductile iron for strength.GB/T 1348 |
| Wall Thickness | 8–20 mm | Thicker for higher pressure or rigidity. |
| Weight | 50–500 kg | Affects installation and support structure. |
| Machining Tolerance | ±0.05 mm | Critical for bearing fits and sealing surfaces.ISO 2768-m |
| Surface Roughness | Ra 1.6–3.2 μm | Smoother for sealing surfaces.ISO 1302 |
| Pressure Rating | 1.0–1.6 MPa | |
| Vibration Level | ≤4.5 mm/s | Higher vibration indicates misalignment or wear.ISO 10816 |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Atmospheric to 2 bar (internal pressure from gear operation, venting required for higher) |
| other spec: | Max shaft speed: 5000 RPM, Vibration limit: 5 mm/s RMS, IP rating: IP65 standard |
| temperature: | -40°C to 150°C (operating range, dependent on seal and material selection) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.
Quoted from the published standard.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Common materials include cast iron, aluminum alloy, and steel. Material grades such as HT250 or QT450 may be specified, depending on strength and cost requirements. The choice affects weight, rigidity, and thermal properties.
The reference range is -20 to 80 °C. Outside this range, seal integrity and lubricant viscosity may be affected. Always verify the specific model's limits with the manufacturer.
Higher IP ratings (e.g., IP65) are suitable for dusty or wet environments, providing better protection against contaminants. The required rating depends on the operating environment.
According to ISO 10816, a vibration level above 4.5 mm/s may indicate misalignment, wear, or other issues. It is a signal to inspect the gearbox and its mounting.
