Abstract

The utility model relates to a cylindrical roller bearing which is composed of an inner sleeve ring, an outer sleeve ring, rollers and a remaining mechanism. The utility model is characterized in that each roller forms a hollow structure; a pin shaft supported by both end covers penetrates in the middle of each roller. The utility model has the advantages that the number of the bearing rollers is relatively large, and thus radial load can be greatly borne; the remaining mechanism can use steel parts, thus steel can be greatly saved, and the production cost can be reduced. The bearing is the ideal cylindrical roller bearing used for rail steel machines.

Description

Roller bearing

The utility model relates to a kind of bearing, the roller bearing of using on particularly a kind of rolling mill.

At present, can bear heavier radial load, often realize, and existing rolling mill bearing is because retainer is occupying a large amount of spaces, so increasing of bearing roller quantity has been subjected to influence by the quantity that increases roller in order to make the rail steel machine bearing.

The purpose of this utility model provides a kind of roller bearing, and this bearing as much as possible increases the quantity of roller by changing the structure of retainer, thereby improves the ability that the rail steel machine bearing bears radial load, overcomes existing deficiency with the rail steel machine bearing.

The purpose of this utility model can realize by following embodiment:

The utility model is made up of outer collar, inside race, roller and retaining mechanism, outer collar, inside race are identical with existing bearing, be characterized in, axial center hole is arranged on the roller, each roller links together by each bearing pin of retaining mechanism, be that roller is through on the bearing pin by its center hole, the direct sliding contact of roller and roller, roller and outer collar and inside race.Inner end cap, outer end cap and bearing pin are arranged on the retaining mechanism, and bearing pin has several, and what promptly having, what bearing pins roller is just had.Bearing pin is contained on the roller back and links together by spot welding or rivet hot and inside and outside end cap, and roller rotates on bearing pin during use.

The utility model can be made single-row, biserial, four row or multiple row roller bearings according to the quantity of outer collar.

The utility model has the advantages that: the quantity of roller takes up room owing to being provided with retainer, so it is more relatively, retaining mechanism is compared the saving material with original retainer, can use Steel Work, solve original retainer when increase in temperature since its be copper spare and very easily wearing and tearing scarce limit, can improve simultaneously the bearing capacity of bearing, reduce production costs, this bearing is a kind of desirable rolling mill bearing.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is an overall structure plan view of the present utility model

Fig. 2 looks partial sectional view for a left side

Shown in Fig. 1-2, this bearing is made up of outer collar (1), inside race (5), roller (6) and retaining mechanism, outer collar (1), inside race (5) are identical with existing bearing, be characterized on the roller (6) axial center hole being arranged, each roller (6) links together by retaining mechanism and each bearing pin (3), roller (6) and roller (6), roller (6) and outer collar (1) and directly sliding contact of inside race (5).Inner end cap (2) is arranged on the retaining mechanism, outer end cap (4) and bearing pin (3), bearing pin (3) has several, what promptly having, roller (6) is just had what bearing pins (3), bearing pin (3) is after loading onto roller (6), logical keep spot welding or rivet hot and inside and outside end cap and link together, during use, roller (6) is gone up at bearing pin (3) and is rotated.Thick in the middle of the bearing pin (3), two is thin, and middle thick part slightly is longer than roller (6), and the thin part in its two adds reserves the riveting amount man-hour.Retaining mechanism outer end cap (4) is identical with the corresponding hole of inner end cap (2) pitch-row and can pass bearing pin (3) smoothly.

Claims

1, a kind of roller bearing, form by outer collar (1), inside race (5), roller (6) and retaining mechanism, it is characterized in that on the roller (6) axial center hole being arranged, each roller (6) links together by each bearing pin (3) of retaining mechanism, roller (6) and roller (6), roller (6) and outer collar (1) and directly sliding contact of inside race (5); Inner end cap (2), outer end cap (4) and bearing pin (3) are arranged on the retaining mechanism, and bearing pin (3) has several, and what promptly having, roller is just had what bearing pins (3), and bearing pin (3) links together by spot welding or rivet hot and inside and outside end cap loading onto roller (6) back.

2, bearing according to claim 1 is characterized in that bearing pin (3) is middle thick, and two is thin, and middle thick part slightly is longer than roller (6), and the thin part in its two adds reserves the riveting amount man-hour.

3, bearing according to claim 1 is characterized in that retaining mechanism outer end cap (4) is identical with inner (2) corresponding hole pitch-row.

4, bearing according to claim 1 is characterized in that it can make single-row, biserial, four row or multiple row roller bearings according to the quantity of outer collar.
