Abstract

The utility model relates to a super-plastic wear-resistant oil-bearing cradle roll for the supporting and operating of the conveyer belt. The utility model is characterized in that one end of the main shaft of the cradle roll is sheathed with a horizontal oil-bearing lower rubber brick and a horizontal oil-bearing upper rubber brick, and the horizontal bracing needle rollers are evenly arranged between the upper rubber brick and the lower rubber brick. The tile-shaped wearing pieces with metal powder are arranged between the needle rollers. Besides, the other end of the main shaft is sheathed with a sloped oil-bearing lower rubber brick and a sloped oil-bearing upper rubber brick, and the needle rollers are evenly arranged between the upper rubber brick and the lower rubber brick. The fan-shaped friction plates are arranged between the needle rollers. The upper and lower rubber bricks of the roll and the friction plates are made by the ultrahigh molecular weight polyethylene synthetic plastics. The utility model has the advantages of good lubricity, low attrition rate, long service life, high bearing performance, low noise and good anti-corrosive performance.

Description

Super-plastic wear-resistant oil-bearing cradle roll

The utility model belongs to the improvement of belt conveyor idler pulley structure.

At present, belt conveyer is to be widely used in the visual plant that coal, mining industry, storage etc. transmit industries, and the idler pulley below its belt conveyor is the key component that supports operation, plays a part to support to transmit adhesive tape.Because during belt transportation, be triangular form, the heavy form that is of idler pulley is the downward triangular form in summit in fact, existing idler pulley material, structure is that the steel pipe that always adopts for many years becomes liner with the cast iron finished surface, overlap common steel bearing, because idler pulley is that heeling condition is by dress on belt conveyer, its bearing is vertical with axle, so behind conveyed article on the adhesive tape, when adhesive tape is heavily downward, the loading angle of bearing is not vertical and parallel, ground work a core and axle sleeve will occur and come off because the bearing length time weares and teares under bevelled angle pressure, and idler pulley is scrapped, even belt conveyor is damaged, cause whole piece conveyer parking maintenance, both influenced the normal operation of conveyer, cause increase maintenance work intensity and bearing to scrap in a large number again.

The purpose of this utility model provides that a kind of lubricity is good, abrasion factor is low, the super of long service life moulded wear-resisting oil-containing idler pulley.

The utility model is achieved in that at idler pulley main shaft one end and is socketed with abrading block and last abrading block under the horizontal oil-containing, is laid with the horizontal support needle roller between upper and lower abrading block, is provided with a watt shape friction lining between needle roller; Be socketed with abrading block and last abrading block under the inclined-plane oil-containing at the main shaft other end, between the upper and lower abrading block in inclined-plane, be laid with needle roller, be provided with fan-shaped friction lining between its needle roller.For improving leak tightness, be provided with piston ring in following abrading block outer end, be provided with sealing shroud at the main shaft two ends, be provided with piston ring in the sealing cover, seal cover cap is housed at the sealing shroud two ends, thereby forms the sealing of 3 roads; For making idler pulley when operation wearing and tearing little, improve lubricity, its middle part is provided with volume whelk blade and is marked with lubricating oil between main shaft and cylinder, lubricating oil can be seeped on needle roller and the Friction disk by the alveolus hole on the last abrading block and help cunning, its flight can be rolled onto lubricating oil the upper end, makes that abrading block and needle roller obtain sufficient fluid under its level.

For making idler pulley long service life, anticorrosion, noise reduction sound, the upper and lower abrading block of its cylinder, Friction disk all adopt the ultra-high molecular weight polyethylene synthetic plastics to make.

Compared with the prior art the utility model has that lubricity is good, abrasion factor is low, long service life, firmly, advantage such as flexible, load-bearing property height, corrosion prevention, noise be low.

Below in conjunction with accompanying drawing the utility model is done to describe:

Fig. 1 is the utility model structural representation

Fig. 2 is that Fig. 1 left side is looked, scheme drawing is looked on the right side

Fig. 3 is Figure 1A-A cross-sectional schematic

Fig. 4 is Figure 1B-B cross-sectional schematic

Referring to accompanying drawing: be socketed with abrading block 13 and last abrading block 11 under the horizontal oil-containing at idler pulley main shaft 1 one ends, last, following abrading block 11, be laid with 4 horizontal support needle rollers 12 between 13, a watt shape containing metal powder friction lining 14 is housed between needle roller 12, the other end at main shaft 1 is socketed with abrading block 6 and last abrading block 8 under the inclined-plane oil-containing, on the inclined-plane, following abrading block 8, uniform between 64 needle rollers 7 are housed, fan-shaped Friction disk 10 is housed between its needle roller 7, it is abrading block 13 down, 6

Friction disks

14,10 and needle roller 12,7 play a part to help sliding reduce friction and support load-bearing, at main shaft 1 two ends sealing shroud 4 is housed, in the sealing cover 4 piston ring 3 is housed, play dustproof, waterproof, anti-leakage of oil effect, in following abrading block 6 outer ends piston ring 15 is housed, load onto seal cover cap 2 in sealing shroud 4 outer ends, thereby strengthened the sealing effectiveness at main shaft 1 two ends.For improving the lubricating oil effect, its middle part is equipped with volume whelk blade 9 and is marked with lubricating oil between main shaft 1 and cylinder 5, when cylinder 5 rotates, can drive flight 9 rotates, lubricating oil is rolled onto the upper end, makes its upper end and the part of spindle parallel needle roller 12 obtain abundant oil lubrication (seeing Fig. 1, Fig. 2, Fig. 3, Fig. 4).
