Crossed Helical Gear: The Versatile Gear Transmission

Crossed helical gears are a type of gear transmission that offers a wide range of applications and benefits. They are widely used in various industries due to their reliability, accuracy, and high transmission efficiency. Let's explore the features, advantages, and maintenance of crossed helical gears.

Features and Classification

Crossed helical gears belong to the category of intersecting shaft gear transmissions. They can be further classified into straight tooth bevel gear transmission and curved tooth bevel gear transmission.

The straight tooth bevel gear transmission involves two peripheral lines intersecting at a 90° angle. It is commonly used and easy to manufacture and install. However, it is less stable, has a lower bearing capacity, and is suitable for low-speed operations with small loads.

On the other hand, the curved tooth bevel gear transmission offers a larger intersection and coincidence between the two shafts. It provides stable operation, high bearing capacity, significant axial force, and is suitable for high-speed transmissions with heavy loads.

Ventajas y Material

Compared to other transmissions, crossed helical gears have several advantages. They provide reliable and accurate motion transmission with a constant instantaneous transmission ratio between the two wheels. The circumferential speed and power range of crossed helical gears are comprehensive, while maintaining high transmission efficiency (generally 0.94-0.99). They also have a long service life, compact structure, and simple maintenance.

Crossed helical gears can be manufactured using various materials, including brass, C45 steel, stainless steel, copper, POM, aluminum, and alloy. The choice of material depends on the specific application requirements.

Instalación, mantenimiento y reparación

Proper installation and maintenance play a crucial role in extending the service life of crossed helical gears. Here are some key points to consider:

1. Installation and running-in: Follow the technical requirements during gear installation and run in a pair of new gears under no-load and step-by-step loading conditions for several hours. Clean the gearbox and replace the oil before use.

2. Proper use: Start-up, loading, unloading, and gear shifting should be stable to avoid impact loads and potential damage to the gear teeth.

3. Lubrication system: Regularly check the lubrication system for oil level, oil supply condition, and oil quality. Replace and replenish the lubricating oil based on the manufacturer's specifications.

4. Monitoring: Regularly monitor the operating status, paying attention to any abnormal sounds, overheating, or other signs of malfunction. Consider using automatic detection devices for high-speed, heavy-load, or critical gear transmissions.

5. Protective cover: Install a protective cover for open gear transmissions to prevent dust, chips, and debris from entering the tooth surface, ensuring gear surface integrity and personal safety.
