Lubricating device for bearing on vertical shaft of disc-type separator

Abstract

The invention discloses a lubricating device for a bearing on the vertical shaft of a disc-type separator. The lubricating device comprises a vertical shaft, a bearing seat, an upper bearing I, and upper bearing II, a spacer sleeve, a lower bearing, a gland, a lubricating sleeve, a belt pulley and parallel tightening nuts. A blind hole is axially arranged in the center of the vertical shaft. A through hole is arranged at the bottom part of the blind hole. An annular oil groove is arranged on the lubricating sleeve. A small hole is arranged at the bottom of the annular oil groove and is communicated with the upper bearing I on the vertical shaft. A certain clearance is arranged between the spacer sleeve and the inner wall of the bearing seat. A through hole and a hole are respectively arranged on the end surface of the belt pulley and the bottom side surface of the belt pulley. The blind hole at the lower part of the vertical shaft is matched with the upper part of a suction tube. An axial through hole is arranged at the upper part of the suction tube. An air plug is transversely installed in a perforated hole at the middle part of the suction tube. An axial small hole is arranged at the lower part of the suction tube. Axial blind holes staggered with the small hole are arranged around the small hole, wherein the lower part of each axial blind hole is closed. The suction tube is arranged in an oil tank. The invention has the advantages that the accessories are reduced, the damage rate of the accessories is reduced and the lubrication effect is improved; and the structure is simple, the maintenance is convenient and the cost is low.

Description

(1) Technical field: [0001] The invention relates to a bearing lubricating device, in particular to a bearing lubricating device on a vertical shaft of a disc separator. (two) background technology: [0002] The disc separator is a kind of machine that performs separation work through high-speed rotation, and the bearing on the vertical shaft of the disc separator is the main working bearing on the disc separator. Lubrication has a great impact on the fatigue life of the bearing and friction, wear, vibration, etc. Important impact, without normal lubrication, the bearing will not work properly. About 40% of the causes of bearing damage are related to poor lubrication. Therefore, good lubrication of bearings is an effective measure to reduce friction and wear of bearings. At present, the bearing lubrication methods on the vertical shaft of the disc separator mainly include oil drop lubrication, oil pool lubrication, and oil pump lubrication. Drip oil lubrication uses a nee...
