Bevel Helical Gearbox

Bevel Helical Gearbox Features

  • Highly Standard Modular Designed: The bevel helical gearboxes are easily connected with and driven by different types of motors and various input power. The same type of geared motor can be adapted to optioned powers of motors. It is therefore easy to realize a different solution for varied requirements.
  • Ratio: Featured many closely divided ratios and a wide range of them. Very big final ratios can be obtained through combined units to reach extremely low output speeds.
  • Mounting Arrangement: No strict limitation to the mounting arrangement.
  • High Strength, Compact Dimension: Housings of bevel helical gearboxes are made of high-strength cast iron. Gears and shaft gears are finished with a gas carburizing process and precise grounding to sequentially get a high loading capacity of per certain volume.
  • Long Service Life: Under the condition of accurately selecting type size and the normal maintenance and use, main components of our helical bevel gearbox (except those easily-disabled parts) can last as long as more than 25,000 hours. Easily-disabled parts include lubricating oil, oil seals, and bearings.
  • Low Noise: All key components are finished by precise machining, accurate assembly, and finally tested, and therefore, fairly low noise is reached.
  • High Efficiency: The efficiency of the bevel helical gearbox can reach 95%, and The efficiency of the worm reducer can reach 89%.
  • Large radial loading ability.
  • Axial load ability of up to 5% of radial load.

What is a Bevel Helical Gearbox?

A helical bevel gearbox is a type of transmission that is used to transmit torque. The features of bevel helical gearboxes include efficiency in both directions of rotation, high efficiency at any input speed, and reduced backlash. There are different sizes that are available, which allow the unit to handle torques from 80 Nm to 500 Nm. The K series is a complete line of two-stage helical-bevel gear units. They set new standards with their sizes, which are particularly robust.

What is a Bevel Helical Gearbox Used For?

The bevel helical gearbox is similar to spur gears in the way it works, with the main advantage of a reverse module configuration. The spur and helical types have the same number of teeth, but the radial and spur gears must stagger in opposite directions. The bevel helical gearbox is the most commonly used type of gearbox in the industry today. And it is the most efficient device of its kind, operating at over 98% efficiency. The bevel helical gearbox is also perfect for high-load cases, such as power transfer between right-angle and parallel configurations.

Another variation of the bevel helical gearbox is the herringbone gear. This gear has special teeth that face in opposite directions so that it can handle more loads. They are also smoother and quieter than spur gears. A helical gearbox is modular, with individual gears or modules interchangeable to optimize the efficiency of the gearbox. These modular models also allow for the highest quality component integrity.

Both bevel and helical gears can transfer power between axes. A hypoid gear has a high transmission efficiency, while a helical gear has low meshing friction. They can be used in high-speed applications, such as motorcycle gears and bicycle gears. They can also transfer power between two axes that cross. And if you want to get a high-speed transmission device, you should opt for hypoid gear.

Helical Bevel Gearbox Design

Bevel helical gearboxes are designed with one or more helical teeth oriented at a specific angle to the axis. Because the helical teeth are positioned at an angle, the result is a helical gear that is quiet and efficient. The bevel helical gearbox is also more effective at transmitting power between parallel shafts than its traditional counterpart. And unlike conventional gearboxes, helical gearboxes are more durable and reliable than other types of gear.

Straight bevel gears are less common than helical gears. They are often used in automobiles and industrial machinery. They help connect a shaft with its wheels. The bevel surfaces allow the bevel gear to operate at an angle of 45 degrees. These gears are also useful in compressive systems and invert shaft rotation. And they are more flexible, providing higher efficiency, and reducing vibrations. If you need high-quality gear, a helical bevel gearbox is a right choice.

Helical Bevel VS Planetary Gearbox

  1. Planetary gears have high torque than helical gears, there are four points of meshing in a stage in planetary gear reducer while helical gears have one point of meshing in a stage.
  2. The spherical bearing is used in planetary gears while the taper bearing is used in helical gears.
  3. The straight cut along with the wheel of planetary while helical gears are cut at an angle along with the wheel.

Helical Bevel Gearbox Installation Usage & Maintenance

To install the gearboxes, it is necessary to note the following recommendations:

  • (1) Check the correct direction of rotation of the gearboxes output shaft before fitting the unit to the machine.
  • (2) Before mounting with the prime mover and device, please check the reducer's every axial diameter, aperture, key and not key and key slot, to be sure their dimensions are not deviation, and avoid assembling too tight or too loose, unless it will influence the reducer's performance.
  • (3) The mounting on the machine must be stable to avoid any vibration.
  • (4) Whenever possible protect the gear units against solar radiation and bad weather.
  • (5) In the case of particularly long periods of storage (4-6 months), if the oil seal is not immersed in the lubricant inside the gearbox, it is recommended to change it since the rubber could stick to the shaft or may even have lost the elasticity it needs to function properly.
  • (6) Painting must definitely not go over rubber parts and the holes on the breather plugs if any.
  • (7) When connecting with the hollow or solid shaft, please grease the joint to avoid lock or oxidation.
  • (8) Check the correct level of the lubricant through the indicator, if there is one.
  • (9) Starting must take place gradually, without immediately applying the maximum load.
  • (10) Supporting unit is required when using various reducers matched with the motor and the weight of the motor is a little bigger than common.
  • (11) Ensure the motor cools correctly by assuring good passage of air from the fan side.
  • (12) In the case of ambient temperatures <-5°C or > +40°C, please contact the Technical Service.
