Automatic lubrication device of vertical type pump bearing

Abstract

An automatic lubrication device of a vertical type pump bearing relates to pumps. The automatic lubrication device is characterized in that a bearing is arranged in a bearing body; an outer bearing is fixed in the bearing body through an outer bearing gland; a main shaft is arranged in the bearing; a lubricant cavity is arranged at the lower part of the bearing; a lubrication body is arranged between the bearing and the main shaft; an inner bearing is fixed on the main shaft through the lubrication body; a ring-shaped oil storage tank is formed between the outer bearing gland and the lubrication body; a cone-shaped body is arranged on the outer side at the lower end of the lubrication body; a ring-shaped oil storage cavity is arranged at the inside diameter at the lower end of the lubrication body; an oil supply hole is formed at the upper part of the ring-shaped oil storage cavity; the oil supply hole is mutually communicated with the oil storage tank at the upper part of the bearing; and the oil storage tank is mutually communicated with the bearing. Therefore, lubricant in the lubricant cavity easily runs upward, the oil supply effect is good, the lubrication effect is good, the operation reliability is high, the service life of the pump is long, and the automatic lubrication device is suitable for the vertical type pump.

Description

technical field [0001] The invention relates to pumps, in particular to an automatic lubricating device for vertical pump bearings. Background technique [0002] We know that the existing vertical pump bearing lubricating device is to have a bearing in the bearing body, the bearing outer sleeve is fixed in the bearing body through the bearing outer cover gland, the bearing inner sleeve is fixed on the main shaft through the shaft sleeve, and the lubricating oil is installed under the bearing. cavity. This kind of vertical pump bearing lubricating device, because there is a lubricating oil chamber under the bearing, the lubricating oil in the lubricating oil chamber is not easy to go up, and the lubricating oil entering the bearing also quickly flows into the lubricating oil chamber, the oil supply effect is poor, and the lubricating effect is poor. Low operational reliability and short pump life. Contents of the invention [0003] The technical problem solved by the pres...

Problems solved by technology

[0003] The technical problem solved by the present invention is that the lubricating oil in the lubricating oil cavity is not easy to go up, and the lubricating oil entering the bearing also quickly flows into the lubricating oil cavity, resulting in poor oil supply effect, poor lubricating effect, low operating reliability and short pump life To solve the problem, provide a vertical pump bearing automatic lubricating device with easy upward movement of the lubricating oil in the lubricating oil chamber, good oil supply effect, good lubricating effect, high operation reliability and long service life of the pump
