Structure of the Worm Gear Unit
The Worm Speed Reducer - Replacement of Nord SMI Worm Gear Units SK1SMI40 consists of various components, each serving a specific purpose:
1. Dual Small Gear Shaft Bearings
The two bearings support and maintain precise alignment of the gears and shafts, isolating and protecting the motor bearings and providing smooth and quiet operation.
2. Worm and Small Gear
The worm is made of fine-grained bronze alloy, minimizing wear and providing maximum strength and durability. The surface-hardened alloy steel small gear has optimized tooth profiles, maximizing gear contact and prolonging the lifespan.
3. Aluminum Alloy Housing
The lightweight aluminum alloy housing offers high strength, optimal heat dissipation, and natural corrosion resistance.
4. Motor Coupling
The motor coupling ensures accurate alignment of the motor shaft, minimizes wear, and provides a low-clearance, high-strength connection.
5. Output Shaft
The output shaft is available with a hollow bore and single or double-sided shaft options.
6. Output Bearings
The oversized bearings provide high radial and axial load capacity and long service life.
7. Oil Seal
The double-lip oil seal provides additional sealing and protection to prevent component damage.
