Abstract
A scroll compressor includes a rotor, a stator, a rotary shaft, an end bracket, an orbiting scroll, a fixed scroll, a suction type cooling fan, and a discharge brush. The discharge brush is fixed to the end bracket facing the cooling fan by a fixing member attached in a radial direction relative to the rotary shaft, and one end of which is in contact with the rotary shaft, in a space secured by the clearance.
Claims4
A scroll compressor comprising:
- a rotor that is stored in a motor casing;
- a stator that is stored in the motor casing, and drives the rotor to rotate;
- a rotary shaft that is held by bearings, and rotates integrally with the rotor;
- an end bracket through which one end portion of the rotary shaft passes, and which seals the motor casing;
- an orbiting scroll that supports the other end portion of the rotary shaft, and orbits as the rotary shaft rotates;
- a fixed scroll that is disposed facing the orbiting scroll;
- a suction type cooling fan which is fixed to the one end portion of the rotary shaft while being apart by a clearance from the end bracket, and which suctions outside air through a suction port provided in an end surface of a fan cover, the end surface facing the end bracket, and generates cooling wind for cooling the fixed scroll or the orbiting scroll in the fan cover, as a rotary vane accommodated in the fan cover rotates;
- a discharge brush which is fixed to the end bracket facing the cooling fan by a fixing member attached in a radial direction relative to the rotary shaft, and one end of which is in contact with the rotary shaft, in a space secured by the clearance;
- and
- a counter weight that is provided in the one end portion of the rotary shaft, the one end portion being located adjacent to the cooling fan.
