Ceiling-fan motor

Abstract

The invention relates to a ceiling-fan motor, comprising a motor upper shell (3), a motor lower shell (6), a motor shaft (1), an upper bearing (2), a lower bearing (7), a motor stator (4) and a motor rotor (5), wherein the motor rotor (5) is arranged outside the motor stator in a matching mode; the center of the motor upper shell (3) is provided with an upper bearing chamber (31); the upper bearing (2) is positioned in the upper bearing chamber (31) and sleeved on the motor shaft (1); the center of the motor lower shell (6) is provided with a lower bearing chamber (61); the lower bearing (7) is arranged in the lower bearing chamber and sleeved on the motor shaft (1); and the motor rotor (5) is arranged in the inner circles of the motor upper shell (3) and the motor lower shell (6). The ceiling-fan motor is characterized by further comprising a wave-shaped spring gasket ring (8) which is arranged in the lower bearing chamber (61) and positioned at the bottom of the lower bearing (7); the upper bearing (2) is in clearance fit with the upper bearing chamber (31); and the lower bearing (7) is in clearance fit with the lower bearing chamber (61). The upper bearing, the lower bearing and the motor rotor are maintained at proper positions; the radial and axial positioning precision of the upper bearing and the lower bearing is improved; the rotary precision is improved; the vibration is reduced; and the bearing noise caused by resonance is avoided.

Description

technical field [0001] The invention relates to a motor for a ceiling fan. Background technique [0002] Currently used ceiling fan motors have an interference fit between the motor bearing and the bearing chamber. This structure is difficult to install during the production process, and it is easy to cause the edge to be stuck and the bearing to be damaged, resulting in poor motor performance and high noise generated by the bearing. Affect the overall quality and life of the motor. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a device that can effectively solve the problems of poor low-pressure jogging and difficult equipment in the production process, reduce the phenomenon of dragging edge jamming and bearing damage in the assembly process, and reduce bearing noise. A ceiling fan motor. [0004] In order to achieve the above object, the present invention is achieved in that it is a ...
