Description

Open bearing with dust cover

Technical Field

The utility model belongs to the technical field of the bearing, concretely relates to open bearing with shield.

Background

The bearing is an important part in modern mechanical equipment, and generally comprises an inner ring, an outer ring and a roller, and the shape of the bearing is different according to different application scenes.

In machinery such as car, motorcycle, partial bearing is in the oil bath environment at the during operation, and the bearing that uses in the oil bath environment of current is mostly open bearing, is in non-sealing state because of the lubricating oil in the oil bath environment, and after bearing operation a period, outside impurity can get into lubricating oil in, gets into inside the bearing via lubricating oil again, makes the inside wearing and tearing of bearing accelerate, influences the life of bearing, influences the operation of whole mechanical equipment.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a take open bearing of shield, the shield neither influences the lubricating oil lubrication, can block the impurity in the oil bath again.

1 in order to realize above-mentioned purpose, the utility model discloses a technical scheme is: the utility model provides an open bearing with shield, includes outer lane, inner circle and roller, still includes the shield that sets up in the roller both sides, be equipped with a plurality of through-hole on the shield, the shield is whole to be netted.

Among the above-mentioned technical scheme, compare in current open bearing and increased netted shield, when being in the oil bath environment, the shield can stop inside the impurity entering bearing in the oil bath, does not influence inside lubricating oil business turn over bearing again simultaneously, prolongs bearing life when guaranteeing lubricated effect.

2 as the utility model discloses a further setting, the aperture of through-hole is between 100 mu m ~300 mu m.

Among the above-mentioned technical scheme, inside most impurity got into the bearing can be blockked to the through-hole in this aperture range, and enabled lubricating oil smooth and easy, convenient processing simultaneously.

3 as the utility model discloses a further setting, the shield is including being annular flaky shield main part and the butt portion that sets up the axial cross-section of following the department outside the shield main part and be the Jiong font, the opening of butt portion is towards the inner circle, the shield main part passes through connecting portion with the butt portion and connects, be equipped with the annular mounting groove that supplies the butt portion butt on the medial surface of outer lane, butt portion and mounting groove interference fit.

Among the above-mentioned technical scheme, the convenient shield of shape of butt portion installs to the mounting groove in, makes the shield of installation completion can not remove or break away from the mounting groove at the bearing operation in-process simultaneously, guarantees that the shield blocks the effect of impurity.

4 as the utility model discloses a further setting, the interior edge of connecting portion is connected with the outer edge of shield main part, and the outer edge of connecting portion is connected near the border of roller with butt portion, connecting portion are by interior edge to the direction slope of following to being close to the roller outward.

Among the above-mentioned technical scheme, connecting portion are by interior edge to outer along the direction slope that is close to the roller, and butt portion and connecting portion form the structure of similar buckle, make things convenient for butt portion installation to advance the mounting groove, also prevent that the butt portion that the installation was accomplished from breaking away from in the mounting groove.

5 as the utility model discloses a further setting, connecting portion and shield main part are at 130 ~150 between towards the contained angle of roller one side.

Among the above-mentioned technical scheme, the contained angle is when above-mentioned angle, has both made things convenient for the shield installation, guarantees the intensity of shield again.

The present invention will be further described with reference to the accompanying drawings.
