Helical Bevel Gear

Helical bevel gear refers to the tooth line on the crown wheel in the production shape. It is a straight bevel gear that does not pass through the cone top. Continuous bevel gear pair in the transmission process is relatively fewer teeth, easy to produce impact, information instability, and noise. Helical bevel gear pairs of bull gears and pinion gears have equal and opposite helical angles. Its fit degree is greater than that of straight bevel gear pair. Therefore, at high-speed operation, noise, and vibration are significantly reduced, and the number of helical teeth of the bevel gear pair can be relatively reduced so as to obtain a larger transmission ratio and compact structure.

Helical Bevel Gear Feature:

Helical teeth: The teeth of helical bevel gears are angled, which makes for smooth and efficient power transmission. The crooked teeth also help reduce noise and vibration during operation.

Spiral pattern: The teeth are cut into a spiral pattern, which causes the teeth to come into contact with each other gradually. This helps reduce impact loads and gear wear.

High load capacity: Helical bevel gears can handle high loads and torque levels, making them ideal for heavy-duty applications such as mining, construction, and industrial machinery.

Versatility: Helical bevel gears can be designed to meet various specifications, including gear ratio, load capacity, and noise level. This makes them a common choice for many different applications.

Good efficiency: Instead of efficiency like spiral bevel gears, spiral bevel gears still offer good levels of efficiency, with some designs achieving up to 98% efficiency.

Bevel Gear Uses:

Automotive applications: Bevel gears are commonly used in automotive differentials to transfer power from the drive shaft to the wheels. They are also used in steering systems and power take-off units.

Industrial machinery: Bevel gears are widely used in industrial machinery, such as machine tools, printing presses, packaging equipment, etc. They can be used to transmit power at right angles between axes, or to change the direction of rotation.

Robotics and automation: Bevel gears are widely used in robotics and automation systems, where they can be used to transmit power, change the direction of motion, and adjust the speed of rotational motion.

Household appliances: Bevel gears are used in many household appliances such as washing machines, vacuum cleaners and power tools. They are used to transfer power between the motor and the drive shaft, or to change the direction of motion.

Marine applications: Bevel gears are used in Marine propulsion systems, where they transfer power from the engine to the drive shaft. They are also used in steering systems and winches.
