Composition Structure
- Double small gear shaft bearings: Two bearing supports can keep the gear and shaft precisely aligned, isolate and protect the motor bearing, and provide smooth/quiet operation.
- Worm small gear: The surface-hardened alloy steel gear has an optimized tooth shape, which can maximize gear contact and provide longer service life.
- Aluminum alloy housing: Lightweight, high strength, optimal heat dissipation, naturally corrosion-resistant.
- Worm: Fine-grained bronze alloy can minimize wear and provide maximum strength and durability.
- Motor coupling: Ensure accurate alignment of motor shaft, minimize wear, and provide low clearance/high strength connection.
- Output shaft: Also provides hollow and single or double-sided shaft models.
- Output bearing: Extra-large bearings provide high radial and axial load capacity and long service life.
- Oil seal: Double-lip oil seals provide additional sealing and protection to prevent component damage.
The composition structure of the Worm Speed Reducer-Replacement of Nord SMI Worm Gear Units SK1SMI31 is unique, and each part plays an important role in ensuring its efficient and reliable operation.
