Technology Overview

1. Introducing Globoid Worm Gear:

- Advantages of High Reduction Ratio and Simple Structure: Double-enveloping worm gears, known as globoid worm gears, offer a simple yet efficient solution to common issues such as heat generation and premature damage. Their high reduction ratio is a key advantage.
- Unique Enveloping Design: As the name suggests, these gears have a distinctive structure that envelops and conforms to the curves of both the wheel and the shaft, providing a precise and secure fit.
- Superior Performance and Stability: Among worm gears developed to date, globoid worm gears exhibit the highest performance-to-efficiency ratio and possess a stable structural design.

2. Cylindrical Worm Gear:

- High Ratio and Simple Structure: Cylindrical worm gears offer a high gear ratio and a straightforward, easy-to-produce structure.
- Low Contact Points: However, they have fewer engagement points between gear teeth, which can lead to increased heat generation and a higher risk of premature breakage and damage.

3. Globoid Worm Gears:

- High Gear Ratio and Complex Structure: Globoid worm gears provide a high gear ratio but have a seemingly simple yet challenging-to-produce structure.
- Simultaneous Teeth Area Contact: Their structure involves more engagement and continuous sliding contact, resulting in efficient transmission and reduced heat generation.

Comparison of Gear Contact Pattern After Running-in

- Regular cylindrical worm gears have point or line contacts, whereas globoid worm gears have simultaneous area contact. This means multiple gear teeth are engaged and mesh at the same time for maximized force transmission.
- When the gear shaft drive rotates, the contact area gradually expands, resulting in stable and consistent power transmission and increased efficiency and longevity of the product.

5. Process:

- From Start to Finish. We possesses the technological knowledge that is implemented in all stages of production.
- We have developed algorithms accounting for geometry and topology from product design, modulation, manufacturing, and performance testing.
- Simulating our gear reducers and gear contact structure virtually with digital simulation programs.

Problem & Solution

Market Problem: Addressed by Globoid Worm Gears

1. Traditional Gear Design Issues:

Common-Causes-Of-Gear-Failure, Globoid Worm Gear, Model Globoid Worm Drive, Worms and worm gears, Worm Gear, globoid worm, Enveloping worm gear, Double Enveloping Worm Gearsets, Double-envelop worm gear sets, Double enveloping Worm Gear, Cone Drive Double Enveloping Worm Gear, — Gear problems are pretty common-and natural

- Lack of Design Technologies: Outdated or manual design processes lead to inefficiencies and potential errors.
- Built Without Considering Machinery Use: Gears might not be optimized for specific machinery, causing performance issues or compatibility problems.
- Outdated Design for Core Roles: Existing gears might be bulky, inefficient, or prone to wear due to older design principles.

2. Limitations of Traditional Gear Applications:

- Using Different Gear Levels: Multiple gear stages might be needed to achieve desired ratios, increasing complexity and size.
- Clear Separation of Gear Technology: Different gear types for specific purposes limit flexibility and efficiency when combined.

Mekonglink Solution: “Power + Precision” Worm Gears: The All-in-One Solution

Traditional gear designs often fall into two categories:
- Power Gears: Built for high torque but can be noisy, inefficient, and less precise.
- Precision Gears: Optimized for smooth, quiet operation but may not handle heavy loads.
- The Challenge: Where Power Meets Precision

Many applications require both power and precision simultaneously. Traditional gears force a choice, sacrificing one for the other, or requiring a complex and bulky multi-stage system.

Gear “Power + Precision” Worm Gears – A Better Way
- Power + Precision: Our unique designs, including globoid and cylindrical options, deliver high torque capacity and smooth, precise operation in a single unit.
- Long Life: Engineered for durability and minimal wear, these gears offer extended lifespan and reduced maintenance needs.
- Low NVH: Experience quieter operation with minimal noise and vibration (NVH).
- High Efficiency: Eastern Gear’s worm gears optimize power transfer, minimizing energy loss and maximizing performance.
- Downsizing: Achieve the same results in a smaller footprint compared to traditional multi-stage gear systems.

Application & Case

Development of a 5 DoF collaborative robot arm

Increased Payload: Their goal is to achieve a 50% increase in payload capacity compared to similar cobots. This means the arm can handle significantly heavier objects.
Reduced Manufacturing Cost: They aim for a 35% reduction in manufacturing costs, making the cobot more affordable.
Key Technology: Globoid Worm Gears – The secret weapon here is the use of globoid worm gears in the arm’s joints. These gears offer several advantages:
- High Reduction Ratio: They can significantly reduce speed while increasing torque, allowing the cobot to handle heavier objects.
- Simple Structure: They are relatively easy to manufacture compared to some other gear types, potentially contributing to the cost reduction goal.
- Superior Performance: Globoid worm gears can offer better efficiency and stability compared to traditional worm gears, potentially improving the cobot’s overall performance.
