Abstract

The utility model discloses a work roll thrust bearing, which comprises a shaft rod; a deep groove ball bearing and a thrust ball bearing are arranged at the outer side of the shaft rod; and the diameter of the deep groove ball bearing or the thrust ball bearing is 2 to 6 times that of the shaft rod. The work roll thrust bearing has the advantages that: 1, because the deep groove ball bearing and the thrust ball bearing are arranged at the outer side of the shaft rod, the radial force of a work roll on a thrust shaft can be eliminated, abrasion of the thrust bearing is reduced, and the thrust bearing is convenient to install; and 2, the size of the bearing is increased, the strength of the thrust shaft is enhanced, and the service life of the thrust bearing is further prolonged.

Description

Worker's roller thrust bearing

Technical field

The utility model relates to a kind of thrust bearing, particularly a kind of thrust bearing that is used for worker's roller.

Background technique

Worker's roller thrust bearing is the special bearing that is used for the work roll axially locating; (1800r/min) its load is big when producing the line high speed operation, and load has very big impact, stuck the burning out to such an extent as to thrust bearing wearing and tearing temperature raises; Cause worker's roller to come off and cause reduction of speed to be shut down; The number of times that causes roll change in a day has badly influenced the normal operation and the steel band quality of production line, and has expended a large amount of manpower and materials up to surplus ten times because bearing breaks.A kind of thrust bearing as shown in Figure 1 is located in the fitting seat at two ends of work roll, comprises outer ring 21, inner ring 23 and roller 22; Roller is located between outer ring and the inner ring, and in the operation of rolling, the end face of upper and lower work roll is withstood in the outer ring of bearing; Drive down at the high speed rotating of work roll, the frictional force that produces between work roll and the bearing outer ring makes the bearing outer ring high speed rotating, and the outer ring of this bearing, inner ring and roller are bearing larger axis from the work roll generation to power; Its problem is that roller end face is the face contact with contacting of outer ring, is difficult for forming oil film; Its end wear is bigger, reduces the working life of bearing, and lubricant oil is thrown to the inwall of outer ring easily; Can not flow out the accumulation of impurities in causes heat and the lubricant oil, the limit speed and the life-span of further having reduced bearing smoothly.

Summary of the invention

The utility model technical problem to be solved provides a kind of worker's roller thrust bearing, strengthens its intensity and prolongs its working life.

The said worker's roller of the utility model thrust bearing, running shaft is contained in the bearing outside, and the running shaft outside is equipped with deep groove ball bearing or thrust ball bearing and is positioned at bearing outside.

In addition, the diameter of said deep groove ball bearing or thrust ball bearing be shaft diameter 2-6 doubly.

Setting sleeve and jump ring are housed between deep groove ball bearing and the bearing outside.

One disk is housed on the running shaft can be along running shaft slip or one-body molded with running shaft; Its radius is greater than the radius of running shaft; Thrust ball bearing is contained in disk one side and can pushes against bearing outside; Deep groove ball bearing is contained in the disk opposite side, and setting sleeve and jump ring are housed between deep groove ball bearing and the bearing outside.

The said worker's roller of the utility model thrust bearing, its advantage is following:

1. deep groove ball bearing and thrust ball bearing are installed in the axostylus axostyle outside, can eliminate the radial force of worker's roller to thrust shaft, reduce the thrust bearing wearing and tearing, and are convenient to install;

2. increase bearing size and strengthen the intensity of thrust shaft, the working life of further having improved thrust bearing.

Fig. 1 is the structural representation of existing worker's roller thrust bearing;

Fig. 2 is the schematic cross-section of the said worker's roller of the utility model thrust bearing.

Embodiment

Worker's roller thrust bearing, its structure is following:

As shown in Figure 2, the said worker's roller of the utility model thrust bearing, running shaft 3 is contained in the bearing outside 1; The running shaft outside is equipped with deep groove ball bearing 4 and thrust ball bearing 2 and is positioned at bearing outside, and in addition, the diameter of said deep groove ball bearing 4 or thrust ball bearing 2 is 2-6 a times of shaft diameter; The working life that can increase bearing size and strengthen the intensity of thrust shaft and improve thrust bearing like this; One disk is housed on the running shaft 3, and said disk can be along running shaft 3 slips or one-body molded with running shaft 3, and its radius is greater than the radius of running shaft; Thrust ball bearing 2 is contained in disk one side and can pushes against bearing outside; Deep groove ball bearing 4 is contained in the disk opposite side, and setting sleeve 5 and jump ring 6 are housed between deep groove ball bearing 4 and the bearing outside, can be limited in thrust ball bearing 2 on the running shaft 3 better like this and it is operated steadily.

During use, the worker's roller that can the rotation on the thrust bearing be coupling, and drive the rotation of worker's roller; Through test shows; Thrust bearing only needs the time-based maintenance secondary weekly after reaching the standard grade and using, follow-up the needs safeguard it again, has improved the break shortcoming of the steel band degradation that causes of thrust shaft.

In sum, the utility model provides the thrust bearing of the worker's roller with good strength and smoothness, improves its life-span and increases the pressure rolling yield of products.
