Planetary gearboxes are an excellent solution for providing high torque and low speed rotation. Planetary gearboxes are used in various industrial applications such as lever mechanisms, transportation vehicles, aerospace systems, and many others. The unique feature of planetary gearboxes is their compactness and high strength at high torque loads, which makes them effective for heavy engineering tasks, especially in combination with quality conveyor components.
Feature of operation of planetary gearboxes
A planetary gearbox is a mechanism for transmitting rotational torque, which consists of a central wheel rotating around its axis and planetary wheels rotating around the central wheel. Planetary gearboxes have a complex design compared to worm gearboxes. For example, the housing of Bonfiglioli planetary gearboxes is made of high-strength cast iron, gears are installed onto a specialized driver that self-centers for optimal load distribution. It can have 1 to 4 stages of reduction (most commonly used is the two-stage planetary gearbox). Those with a reinforced shaft have tapered roller bearings, making them an ideal option for heavy-duty operating conditions. A planetary motor-gearbox has a drive from an electric motor or a hydraulic motor.
Features to consider when selecting a planetary gearbox
When considering the technical nature of planetary gearboxes, it is important to select them based on the following key criteria:
- Power rating: When selecting and purchasing a gearbox, it is important to pay attention to its power rating and ensure that it can operate with the required load.
- Gear ratio: The gear ratio of a planetary gearbox should correspond to the necessary reduction in torque for the system. It should be noted that planetary gearboxes typically have a high gear ratio, which allows for a significant reduction in torque.
- Operating environment: The operating environment in which the gearbox will be used is also an important criterion if you have decided to purchase a planetary gearbox. When selecting, it is necessary to pay attention to protection from moisture, dust, vibration, and other hazards that can affect the operation of the gearbox. Manufacturers usually indicate the level of protection for gearboxes in specifications, which allows you to choose a model that best suits the needs of a particular system.
The utilization of a planetary gearbox can greatly decrease the expense and dimensions of the drive system.
To aid in the selection of gearboxes, there are specific configurators available. Presently, to properly select Bonfiglioli gearboxes that meet your requirements, we suggest using the Mosaico configurator, which will help you save both time and money.
