Motor Including Bearing Assembly

Abstract

A bearing assembly including a bearing seat, at least one bearing and a shaft is disclosed. The bearing seat includes a chamber, a shaft-coupling hole and a shaft hole. The shaft-coupling hole and the shaft hole intercommunicate with the chamber. The bearing seat has a slit which is adjustable. The at least one bearing is received in the chamber. The shaft extends through the shaft hole and the at least one bearing and includes at least one abutment portion. The at least one bearing abuts the at least one abutment portion. In addition, a motor including a bearing assembly is disclosed.

What is claimed is: 
     
         1 . A motor including a bearing assembly, comprising:
 a housing;   a stator received in the housing;   a bearing seat mounted to the housing and having a slit which is adjustable;   a bearing received in the bearing seat and including an inner race and an outer race;   a shaft extending through the bearing; and   a rotor coupled with the shaft and rotating relatively to the stator.   
     
     
         2 . The motor including the bearing assembly as claimed in  claim 1 , wherein a bottom plate is coupled with a bottom of the housing and includes a seat coupled with an end of the shaft. 
     
     
         3 . The motor including the bearing assembly as claimed in  claim 2 , wherein a support is disposed between the shaft and the seat and is a self-lubricating bearing, an oil bearing or a ball bearing. 
     
     
         4 . The motor including the bearing assembly as claimed in  claim 1 , wherein the inner race has an outer diameter and the outer race has an outer diameter, wherein the bearing seat has a shaft hole, and wherein the shaft hole has a diameter larger than the outer diameter of the inner race and smaller than the outer diameter of the outer race. 
     
     
         5 . The motor including the bearing assembly as claimed in  claim 1 , wherein a positioning ring is disposed between the rotor and the shaft and has an end connected to the inner race of the bearing. 
     
     
         6 . The motor including the bearing assembly as claimed in  claim 3 , wherein the shaft is coupled with an elastic element, and wherein the elastic element has an end connected to an end of the positioning ring, as well as another end connected to an end of the support. 
     
     
         7 . The motor including the bearing assembly as claimed in  claim 1 , wherein the bearing seat includes a horizontal through-hole extending through the slit, and wherein a positioning member extends through the horizontal through-hole to adjust the slit. 
     
     
         8 . The motor including the bearing assembly as claimed in  claim 7 , wherein the positioning member includes a screw and a nut. 
     
     
         9 . The motor including the bearing assembly as claimed in  claim 7 , wherein the horizontal through-hole is provided with inner threads, and wherein the positioning member is provided with outer threads and is threaded through the inner threads of the horizontal through-hole. 
     
     
         10 . The motor including the bearing assembly as claimed in  claim 1 , further including a positioning ring fit around the bearing seat via a hole thereof, wherein the positioning ring includes a slit extending through the positioning ring from an inner periphery delimiting the hole to an outer periphery of the positioning ring, wherein a horizontal through-hole extends through the slit, and wherein a positioning member extends through the horizontal through-hole to adjust the slit.
