Ceiling fan bearing system
A ceiling fan assembly including a stator assembly having a non-rotating motor shaft and stator slidably and non-rotationally coupled to the non-rotating motor shaft, a rotor assembly, a first bearing slidably mounted to the non-rotating motor shaft and rotatably coupling the rotor assembly to the stator assembly, and a first spacer located between the first bearing and the stator assembly to fix the sliding location of the first bearing relative to the stator along the non-rotating motor shaft.
1. A ceiling fan assembly comprising:
a stator assembly having a non-rotating motor shaft and stator slidably and non-rotationally coupled to the non-rotating motor shaft;
a rotor assembly;
a first bearing slidably mounted to the non-rotating motor shaft and rotatably coupling the rotor assembly to the stator assembly; and
a first spacer compressively retained between the first bearing and the stator assembly to fix the sliding location of the first bearing relative to the stator along the non-rotating motor shaft and wherein the first spacer does not extend radially beyond an outer edge of the first bearing.
2. The ceiling fan assembly of claim 1 , further comprising a second bearing and second spacer located on an opposite side of the stator than the first bearing and first spacer, with the second bearing slidably mounted to the non-rotating motor shaft, the second spacer located between the second bearing and the stator.
3. The ceiling fan assembly of claim 2 , wherein the second bearing rotatably couples the rotor assembly to the stator assembly.
4. The ceiling fan assembly of claim 2 , wherein the stator is compressively retained between the first and second spacers.
5. The ceiling fan assembly of claim 2 , wherein the first and second spacers are compressively retained between the first and second bearings.
6. The ceiling fan assembly of claim 5 , wherein the rotor assembly abuts at least one of the first and second bearings.
7. The ceiling fan assembly of claim 6 , wherein the rotor assembly abuts both the first and second bearings.
8. The ceiling fan assembly of claim 7 , wherein the rotor assembly comprises a housing abutting both the first and second bearings.
9. The ceiling fan assembly of claim 8 , wherein the housing is coupled to the rotor such that the housing rotates with the rotor.
10. The ceiling fan assembly of claim 8 , further comprising a spring member provided between the housing and each of the first and second bearings.
11. The ceiling fan assembly of claim 1 , wherein the stator assembly is compressively retained by at least one of the first spacer and first bearing.
12. The ceiling fan assembly of claim 11 , wherein the first spacer is compressively retained between the first bearing and the stator assembly.
13. The ceiling fan assembly of claim 1 , wherein the rotor assembly abuts the first bearing.
14. The ceiling fan assembly of claim 13 , wherein the first bearing is compressively retained between the rotor assembly and the first bearing.
15. The ceiling fan assembly of claim 14 , wherein the rotor assembly comprises a housing that compressively retains the first bearing.
16. The ceiling fan assembly of claim 1 , wherein the non-rotating motor shaft has a shoulder and at least one of the first bearing and first spacer abuts the shoulder.
17. The ceiling fan assembly of claim 16 , wherein the first bearing abuts the shoulder.
18. The ceiling fan assembly of claim 17 , wherein the first spacer circumscribes the shoulder.
19. The ceiling fan assembly of claim 18 , wherein the first spacer is compressively retained between the first bearing and the stator.
20. The ceiling fan assembly of claim 16 , wherein the motor shaft further comprises an aperture configure to allow electrical conduit to pass through to provide power to the stator.
