Abstract
The utility model discloses a heavy load heat supply three-phase asynchronous motor water-cooling bearing room structure, the outer circumference of bearing room casing encircles and the interval is provided with the heat dissipation muscle, and heat dissipation muscle and motor front end housing welded fastening, installs the bearing in the bearing room casing, and the bearing is a mouthful heavy load series bearing, and the bearing enclosing cover is installed in the outside of bearing, and the sealing washer clamp plate is installed in the outside of bearing enclosing cover. The utility model discloses at the indoor installation a mouthful heavy load series bearing of water-cooling bearing, improve the bearing's load capacity, compare the installation with two original bearings and dismantle the maintenance convenience. The outer circumference of the bearing chamber shell is provided with heat dissipation ribs, so that the heat dissipation capability of the water-cooling bearing chamber is improved. The heat generated by the bearing is taken away through a water-cooling heat dissipation mode by a structure that the front end cover of the motor is connected with the water-cooling bearing chamber through a heat dissipation rib. Because the motor front end cover is hollow and is directly connected with the water-cooling bearing chamber, the heat inside the motor is dissipated through the water-cooling bearing chamber, and the integral heat dissipation capacity of the motor is greatly improved.
Description
Technical Field
The utility model relates to the technical field of motors, especially, relate to a heavy load heat supply three-phase asynchronous motor water-cooling bearing room structure.
Background
Because the motor needs heavy-duty operation and operating environment temperature is high, and the bearing capacity requirement to the bearing is higher, two port bearings are adopted to the motor of prior art, improve bearing load capacity, but two port bearings generate heat seriously, and the fault rate is higher, dismantles and maintains the difficulty. The bearing is arranged on the front end cover of the motor, and heat generated by the motor and heat generated by the bearing are mutually influenced, so that the whole motor generates heat seriously, the heat dissipation capacity of the motor is poor, and the safe operation of the motor is influenced.
