Bevel Gearboxes

A bevel gearbox, also known as an angular gear, is a type of gearbox that consists of two bevel gears that mesh together and transfer power between two shafts. The two gears are designed in such a way that their bevel angles fit together.

Winco bevel gearboxes are frequently used when a right angle is needed in the drive direction, as they can change the direction of rotation by 90 degrees. They are often employed in applications where a high torque transfer in a compact size is required, such as in machines.

Bevel gearboxes are available in various sizes within a sealed aluminum housing.

Applications of Bevel Gearboxes / Angular Gear Drives

Bevel gearboxes are used in a variety of machines, such as in machine tools, conveyor systems, and packaging machines. Generally, angular gear drives are frequently used for deflecting and adjusting height.

Bevel Gearboxes as Standard or Custom Solutions from Winco

Bevel gearboxes are often used as standard gearboxes in many industrial applications. Here are some reasons why bevel gearboxes are popular as standard gearboxes:

• Efficiency: Bevel gearboxes generally have higher efficiency than other types of gearboxes, such as worm gears or spur gears. This means they consume less energy and are therefore more cost-effective.
• Versatility: Bevel gearboxes can be used for a variety of applications, as they are available in different sizes.
• Robustness: Bevel gearboxes are robust and durable.
• Quiet Operation: Bevel gearboxes generally operate quietly and generate little to no vibrations during operation.
• Precision: Bevel gearboxes can operate very precisely and allow for accurate torque transfer.

Overall, bevel gearboxes are popular as standard gearboxes in many industrial applications due to their efficiency, versatility, robustness, quiet operation, and precision.

Worm Gearboxes

A worm gearbox is a type of gearbox consisting of a worm and a worm wheel. The worm is a spiral, screw-shaped shaft that engages with the worm wheel. When the worm turns, it moves the worm wheel in a rotary motion.

The worm wheel generally has fewer teeth than the worm and is typically mounted at a right angle to the worm axis.

Worm gearboxes have the advantage of providing a high reduction ratio and high torque, making them suitable for applications where high loads need to be transferred.

Considerations: What to Keep in Mind with Worm Gearboxes

• Lubrication: Worm gearboxes require sufficient lubrication to achieve optimal performance. All worm gearboxes from Winco are lubricated for life and thus maintenance-free.
• Heat Dissipation: Worm gearboxes often generate heat due to the contact between the worm and the worm wheel. Therefore, it is important to ensure that the gearbox can dissipate this heat to prevent overheating.
• Noise Generation: Worm gearboxes can have increased noise levels due to the contact surface between the worm and worm wheel.

Self-locking Worm Gearboxes

A self-locking worm gearbox is a special version of a worm gearbox, where the worm wheel is designed in such a way that it cannot rotate backward easily when no force is applied to the gearbox. This means that the gearbox is "locked" in a certain position and cannot move without external influence.

This type of gearbox has the advantage of providing an additional safety function, which is required in some applications, such as when a drive must be stopped in a dangerous position. Self-locking worm gearboxes are also useful in applications where constant rotation in only one direction is needed, such as in conveyor systems or applications with inclines.

Winco provides self-locking worm gearboxes for many gear ratios.

Construction and Material of Bevel Gearboxes and Worm Gearboxes

Winco bevel gearboxes and worm gearboxes are made from an aluminum housing. Aluminum housings offer several advantages over housings made from other materials, such as steel or cast iron. Here are some reasons why gearboxes are used in aluminum housings:

• Weight: Aluminum is lightweight compared to steel or cast iron, resulting in a lighter gearbox.
• Corrosion Resistance: Aluminum is more resistant to corrosion than steel and cast iron.
• Heat Dissipation: Aluminum is a good heat conductor, meaning it can effectively dissipate heat. This is important because bevel gearboxes and worm gearboxes can generate heat during operation that needs to be dissipated to prevent overheating of the gearbox.
