Worm Speed Reducer-Replacement of Nord Helical Worm Gear Unit SK02050
Introduction
The Worm Gearbox is a multi-stage bevel gear apparatus where the motor shaft and the output shaft form a 90° angle. This allows for flexible installation in situations with limited mounting space. These gearboxes are made of high-strength aluminum or die-cast aluminum, ensuring maximum strength and rigidity while remaining lightweight. They can be further protected through surface treatment. This series has a wide power range, ranging from 0.16 horsepower to 20 horsepower, with output torque of up to 27,350 pounds per inch. The broad range of speed ratios (from 5.37:1 to 330:1) can best meet customers' needs, and the motor can be directly installed without couplings or adapters (NEMA or IEC). We provide Nord brand replacements for helical worm gear reducers, which are of good quality and at a competitive price. It is important to note that our products are replacement parts, not original parts. If you need to purchase original parts, please contact the original supplier.
Structure of Helical Worm Reducer
The helical worm reducer is composed of several parts, each with its own function:
- Gearbox housing: Made of high-strength gray cast iron, it provides a sturdy structure for the gearbox.
- Input shaft and bearings: The input shaft is supported by high-quality bearings, ensuring smooth operation.
- Helical gears: Made of high-alloy steel, the helical gears are surface-hardened for durability.
- Worm shaft and bearings: The worm shaft is supported by high-quality bearings, ensuring smooth operation.
- Worm gear: Welded with special bronze wheel rims, the worm gear is constructed to ensure high reliability.
- Oil seals: Prevent oil leakage and ensure smooth operation.
- Bolt-on output shaft: Ensures easy installation and replacement.
