Novel rotating base

Abstract

The invention discloses a novel rotating base which comprises a shaft and a base. The shaft is connected with an upper cross beam of an alignment carrier roller in a welded mode, the base is connected with a lower cross beam of the alignment carrier roller in a welded mode, an angular contact bearing and a conical roller bearing are arranged between the shaft and the base in a vertically spaced mode, the upper portion of the base is nested in the lower portion of an opening hole in the upper cross beam, an O-shaped seal ring is arranged between the base and the nesting position of the upper cross beam, the part, on the lower end face of the conical roller bearing, of the shaft is sleeved with a gasket, the gasket is tightly pressed to the lower end face of the conical roller bearing through a nut, and a base end cover is connected to the bottom face of the base through fixing parts. The novel rotating base has the advantages that the angular contact bearing and the conical roller bearing are arranged between the shaft and the base, so that the shaft and the base are rotated flexibly; the O-shaped seal ring is arranged between the base and the upper cross beam, the seal performance is good, the alignment effect is good, and the service life is long.

Description

technical field [0001] The invention relates to a rotating base structure. Background technique [0002] Currently, if figure 1 Shown is a known rotating base for self-aligning rollers of belt conveyors, the structure is; first, the shaft 1 and the upper beam of the self-aligning roller are welded, and then the base 2 is welded to the lower beam of the self-aligning roller, Fill the lubricating cavity between the shaft 1 and the base 2 with lithium-based No. 2 grease, and finally install the retaining ring 3 and the washer 4 at the bottom of the shaft 1 to fix them. The disadvantages of this structure are: 1. The lithium-based No. 2 lubricating grease in the lubricating chamber 5 between the shaft 1 and the base 2 will gradually lose over time and reduce the lubrication effect, resulting in inflexible rotation or even inability to rotate; 2. The shaft 1. The retaining ring 3 and gasket 4 installed at the bottom of 1 can bear limited force. For example, when the material tr...

Problems solved by technology

The disadvantages of this structure are: 1. The lithium-based No. 2 lubricating grease in the lubricating chamber 5 between the shaft 1 and the base 2 will gradually lose over time and reduce the lubrication effect, resulting in inflexible rotation or even inability to rotate; 2. The shaft 1. The retaining ring 3 and gasket 4 installed at the bottom of 1 can bear limited force. For example, when the material transported by the belt conveyor has a large impact, it is easy to fail and cause falling off; 3. The sealing performance between the base and the upper beam is poor, and the content of the lubricating chamber Easy to enter impurities and affect the rotation

The disadvantages of this structure are: 1. There is no bearing between the lower end of the center shaft and the base, which will cause inflexible rotation; 2. The sealing performance between the base and the upper beam is poor, and impurities are easy to enter, which affects the rotation

The disadvantages of this structure are: 1. There is no bearing between the lower end of the center shaft and the base, which will cause inflexible rotation; 2. The sealing performance between the base and the upper beam is poor, and impurities are easy to enter, which affects the rotation

The disadvantages of this structure are: 1. There is no bearing between the lower end of the center shaft and the base, which will cause inflexible rotation; 2. The sealing performance between the base and the upper beam is poor, and impurities are easy to enter, which affects the rotation

The disadvantages of this structure are: 1. The sealing performance of the base and the upper beam is poor, and impurities are easy to enter and affect the rotation; 2. Neither the one-way ball bearing nor the deep groove ball bearing can withstand large axial loads. When a large impact occurs, the bearing is easily damaged, which affects the service life
