Structure of the Gearbox

The structure of this model of worm gear reducer consists of:

• Double Small Gear Shaft Bearings: The two bearings support and keep the gears and shafts accurately aligned, isolate and protect the motor bearings, and provide smooth and quiet operation.
• Worm Small Gear: The surface-hardened alloy steel gear has an optimized gear profile that maximizes gear contact and provides longer life.
• Aluminum Alloy Housing: The lightweight, high-strength, and natural corrosion-resistant aluminum alloy housing provides optimal heat dissipation.
• Worm: The fine-grained bronze alloy minimizes wear and provides maximum strength and durability.
• Motor Coupler: The motor coupler ensures accurate alignment of the motor shaft, minimizes wear, and provides a low clearance/high-strength connection.
• Output Shaft: The gear reducer also provides hollow bore and single or double-sided shaft models.
• Output Shaft Bearings: The oversized bearings provide high radial and axial load capacity and long service life.
• Oil Seal: The double-lip oil seal provides additional sealing and protection to prevent component damage.

Advantages of Compact Worm Gear Reducer

The advantages of this compact worm gear reducer are:

• Easy to Assemble and Disassemble: The modular construction of the worm gear reducer makes it easy to assemble and disassemble.
• Protecting and Isolating Motor and Reducer Shaft Bearings: The worm gear reducer protects and isolates the motor and reducer shaft bearings.
• Provides a Strong, High-Strength, Near-Zero Gap Connection: The worm gear reducer provides a strong, high-strength, near-zero gap connection.
