Product Description
Product Description
Connecting the motor and impeller: The bearing box connects the motor to the impeller and drives it through a belt and pulley, allowing the motor to drive the impeller to rotate. This design not only increases the operating efficiency of the fan, but also reduces the occurrence of fan failures.
Supporting bearings: The bearing box plays a role in supporting the bearings, separating them from the wind system and preventing pollution. This design is particularly common in small fans and can use oil-free lubricated bearings.
Improving work efficiency: Through the design of the bearing box, the fan can operate more efficiently, reduce failure rates, and adjust the rotational speed of the motor to change the fan's air volume, thereby meeting different usage needs.
Adapt to different working conditions: The design of bearing housings also varies for different working conditions, such as high or low temperature environments. For example, when the medium temperature does not exceed 80 ℃, oil cooling is used, and when it exceeds this temperature, water cooling is used. For high-temperature fans, high-temperature bearing box 4 is used.
In summary, the fan bearing box plays a crucial role in the design and operation of the fan, not only connecting the motor and impeller to improve work efficiency and reduce failure rates, but also adapting to different working conditions.
