Improvement of bearing housing end cap seal

The transmission part of the blower and induced draft fan of our factory is driven directly by the motor through the elastic coupling. It is equipped with two double row radial spherical can bearings, which are used to lubricate the bearings through the oil pool. It is equipped with an oil ring, but the leak is quite serious. Cause of leakage: When the oil ring is smashed into the inner wall of the end cap, the oil will flow along the surface of the hole wall to the fan shaft on the back of the oil slinger. The gap between the hole and the shaft is 0.1 to 0.3 mm. Due to the high fan speed (about 1000 r/min), it is difficult to form an oil film to prevent leakage. To this end, we have tried the aluminum ring seal.
