Worm Speed Reducer-Replacement of Nord SI Worm Gear Unit SK1SI50

Introduction

The Worm Speed Reducer-Replacement of Nord SI Worm Gear Unit SK1SI50 is a highly versatile and modular worm gear unit that covers a range of industry-standard center distances, from 31mm to 75mm, and torque capacities of up to 3,779 pound-inches. It offers a wide range of standard, single worm and compound worm ratios, ranging from 5:1 to 10,000:1. The series is characterized by a smooth outer surface and individual foot and flange gearboxes, ensuring excellent modularity. This flexibility allows for a wide range of input and output mounting options as well as various output shaft options.

Features

• Universal base and flange mounting housing
• Can adapt to any mounting position
• Easy-to-assemble accessories
• Standard configurations for NEMA, IEC, or solid shaft input
• Can accommodate C-Face motors or brake motors
• Hollow shaft and solid shaft gear sets
• Angular gear sets
• High overload capacity
• Specific application versions
• Soft and quiet operation
• Aluminum housing version, lightweight
• Optional 10:1 helical gear pre-stage and double worm gear units
• Modular, flexible, and widely used
• Output shaft bearings, high load capacity

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: Surface-hardened alloy steel gears with optimized tooth shapes can maximize gear contact and provide longer service life.
• Aluminum alloy housing: Lightweight, high strength, optimal heat dissipation, and naturally corrosion-resistant.
• Flange or torque arm mounting options are available.
• Input configurations: NEMA, IEC, and free input shaft designs are available at any time. Integrated motor mounting is optional. Can adapt to servo motors.
• Worm: Fine-grained bronze alloy can minimize wear and provide maximum strength and durability.
• Motor coupling: Ensures accurate alignment of the motor shaft, minimizes wear, and provides low clearance/high strength connections.
• Output shaft: Also provides hollow bore and single or double sided shaft models.
• Output shaft bearings: Oversized bearings provide high radial and axial load capacity and long service life.
• Oil seal: Double-lip oil seal provides additional sealing and protection to prevent component damage.

Advantages

• Easy to assemble and disassemble.
• Eliminate common frictional corrosion in bushing-mounted inputs.
• Maintain shaft alignment and provide vibration-free torque transfer.
• Protect and isolate motor and gearbox shaft bearings.
• Provide a robust, high-strength, near-zero clearance connection.
• Reduce the likelihood of bearing, shaft, and key failures.

Motors for Worm Gear Reducers

Worm gear reducers are often used in conjunction with electric motors, with the motor providing the power to drive the gear reducer. The gear reducer then reduces the speed and increases the torque of the motor's output shaft, making it more suitable for a wide range of applications. Our company also provides various types of electric motors for sale, which are perfect for use with our worm gear reducers. The combination of our high-quality motors and worm gear reducers can provide you with a reliable and efficient power transmission solution for your application.
