FAN MOTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18488445 titled 'FAN MOTOR
Simplified Explanation
The fan motor described in the patent application includes a preload applying device that applies force to one axial end of the bearing in an axial direction using elastic force. Additionally, a bush is coupled to the outer circumferential surface of the bearing and slidably mounted on the inner circumferential surface of the bearing housing in an axial direction. A protrusion on the bush interacts with a protrusion accommodating groove on the bearing housing to prevent slipping of the outer ring of the bearing.
- Preload applying device applies force to one axial end of the bearing using elastic force
- Bush is coupled to the outer circumferential surface of the bearing and prevents slipping of the outer ring
Potential Applications
The technology described in the patent application could be applied in various fan motors used in appliances, HVAC systems, automotive cooling systems, and industrial machinery.
Problems Solved
This technology solves the problem of maintaining an appropriate preload on the bearing in a fan motor while preventing slipping of the outer ring, which can lead to inefficiencies and potential damage to the motor.
Benefits
The benefits of this technology include improved efficiency and longevity of fan motors, reduced maintenance requirements, and enhanced performance in various applications.
Potential Commercial Applications
The technology could be commercially applied in the manufacturing of fan motors for appliances, HVAC systems, automotive industry, and industrial machinery, providing a competitive edge in terms of performance and reliability.
Possible Prior Art
One possible prior art could be the use of preload applying devices in fan motors to maintain proper bearing preload, but the specific combination of a preload applying device, bush, and protrusion accommodating groove may be unique to this patent application.
Unanswered Questions

This article does not provide a direct comparison to existing methods of maintaining bearing preload in fan motors.
What are the potential cost implications of implementing this technology in fan motor manufacturing?
The article does not address the potential cost implications of implementing this technology in fan motor manufacturing.
Original Abstract Submitted
A fan motor is disclosed. The fan motor includes a rotating shaft, a motor, a bearing, a bearing housing, a preload applying device, and a bush. The preload applying device is disposed between one axial end of the bearing and the bearing housing, and applies force to the one axial end of the bearing in an axial direction by using elastic force. The bush is coupled to an outer circumferential surface of the bearing and slidably mounted on an inner circumferential surface of the bearing housing in an axial direction. A protrusion is formed on one axial end portion of the bush, and a protrusion accommodating groove is formed on an axial inner surface of the bearing housing. Accordingly, the preload applying device can continuously apply an appropriate preload to the bearing, while the bush can suppress slipping of an outer ring of the bearing.
