Problems solved by technology
This will easily cause the motor bearing to run under overload, the temperature of the bearing will rise, the grease will become thinner, and then there will be poor lubrication, which will eventually lead to a shortened service life of the bearing, or even burn out

The invention relates to a lubricating structure of a bearing assembly of a vertical motor for water conservancy and biochemistry, comprising an upper bearing part and a lower bearing part; the upper bearing part and the lower bearing part are set on a rotating shaft to form a whole. The upper bearing part uses a rotating shaft to pass through the bearing outer cover and the bearing inner cover, and the bearing outer cover and the bearing inner cover lock the bearing outer ring on the end cover; two and a half snap rings, the upper oil throwing ring, and the lower oil throwing ring The ring is installed on the rotating shaft; the outer cover of the bearing is provided with a sealing disc. The lower end bearing part adopts a rotating shaft to pass through the bearing inner cover, and the bearing outer cover and the bearing inner cover lock the bearing outer ring on the insulating end cover; the first lower end bearing and the second lower end bearing are provided with a shaft sleeve, and the shaft sleeve is covered with an insulating layer. The invention is beneficial to the discharge of waste grease, can prevent the grease from leaking into the inside of the motor, and can increase the lubricating effect of the NU bearing.
Description
technical field [0001] The invention relates to a lubricating structure for a bearing assembly of a vertical motor used in water conservancy and biochemistry, in particular to a bearing configuration and installation structure for YSL560 series motors. Background technique [0002] YSL series water conservancy and biochemical motors usually adopt V1 and V2 two vertical installations to facilitate the installation of water conservancy equipment or fermentation equipment. Its bearing configuration and installation structure are quite different from those of horizontal motors, and its bearing force and load transmission mode are also special. First of all, since the load is mostly driven by pulleys, the upper bearing has to bear a large radial tension, so cylindrical roller bearings are often used to increase its carrying capacity. Secondly, the bearing at the lower end of the motor bears a large force, and the situation is more complicated. The bearing at the lower end of the...
