  • Patent number: 10495087
    Abstract: A compressor and a method of assembling the compressor are provided. The compressor includes: a shell; a motor arranged in the shell, the motor having a stator, a spacer mounted with a first bearing therein, a drive shaft supported by the first bearing and a rotor fixed onto the drive shaft; a low bearing support; a positioning member positioning the second bearing and being connected to the low bearing support; and a second bearing connected to the positioning member and/or the low bearing support and supporting the drive shaft. Furthermore, the positioning member may be removed from or maintained in the compressor after it is assembled. The present disclosure can avoid the adverse effects of the gravity of the rotor and the drive shaft and/or the magnetic force between the rotor and the stator on positioning the bearings and the drive shaft and can improve positioning accuracy and assembling efficiency.
