The bearing comprises a waist drum type outer ring, wherein two mounting screw holes are formed in two hard ends of the outer ring, a thickening step and a sealing groove are formed in one plane of the two planes, the sealing groove is formed in the other plane of the two planes, and a single-row or double-row steel ball groove is formed in an inner hole of the inner ring.
Description
Technical Field
The utility model relates to a waist drum bearing, in particular to an integrated waist drum bearing.
Background
The bearing is a part for fixing and reducing the friction coefficient of load in the mechanical transmission process, and is used for reducing the friction coefficient in the power transmission process and keeping the center position of the shaft fixed when other parts move relative to each other on the shaft. These bearings are generally composed of an outer race, an inner race, steel balls, a storage shelf and a dust cap, some of which are applied to a bearing housing; such as application No. 201520162771.0, publication No. 2015.07.29, entitled "bearing device" disclosed in chinese patent document; the bearing device comprises a rolling bearing and a bearing seat, wherein the bearing seat comprises a bearing seat body and an installation seat body, the installation seat body is fixed on the bearing seat body, the installation seat body is provided with a support bottom surface, a plurality of installation holes are formed in the installation seat body, a bearing seat hole is formed in the bearing seat body, a front end limiting check ring is arranged at an axial front port of the bearing seat hole, a rear end limiting check ring is arranged at an axial rear port of the bearing seat hole, the rolling bearing is assembled in the bearing seat hole, one axial end of the rolling bearing is in limiting fit with the front end limiting check ring, the other axial end of the rolling bearing is in limiting fit with the rear end limiting check ring, the installation seat body is arranged at the rear end of the bearing seat shaft, the corresponding rolling bearing is arranged on the support bottom surface of the bearing seat body along the axial direction, and the installation holes are distributed in an annular shape. However, the bearing seat body and the outer ring of the product and the like are generally designed in a split structure, so that the production and assembly are inconvenient, and the stability is poor.
Disclosure of Invention
In order to overcome the defects, the utility model aims to provide an integrated waist drum bearing for the field, so that the technical problems that the stability of the existing similar waist drum bearing seat product is poor, and the bearing seat and an outer ring are difficult to be integrally produced and assembled are solved. The purpose is realized by the following technical scheme.
An integrated waist drum bearing comprises an outer ring and an inner ring, wherein steel balls distributed at equal intervals are arranged between the inner diameter of the outer ring and the outer diameter of the inner ring; the outer ring is an outer ring seat, triangular extension edges symmetrically arranged at two ends of the outer ring seat are respectively provided with an installation screw hole, a central ring hole of the outer ring seat protrudes towards the top, and a steel ball is arranged between the central ring hole of the outer ring seat and the outer diameter of the inner ring. Thereby this waist drum bearing's outer lane and outer lane seat integrated into one piece have left out the outer lane structure, have made things convenient for holistic assembly, have improved holistic firmness and stability.
The ring opening of the inner ring is higher than the central ring hole of the outer ring seat. Thereby facilitating the arrangement of the following transverse screw holes, the sleeving and fixing with external equipment and the addition of lubricant.
And at least one side of the inner ring higher than the ring opening of the outer ring seat is provided with a transverse screw hole. Thereby facilitating the fixing of the inner race of the drum bearing to an external device or component through the transverse screw hole.
And a single row or double rows of steel balls are arranged between the central ring hole of the outer ring seat and the outer diameter of the inner ring. The double-row steel balls in the two steel ball structures have better stability, but the size of the double-row steel balls can be increased.
The utility model has reasonable structural design, wide application range, convenient installation and use, and good stability and firmness; the bearing is suitable for being used as an integrated waist drum bearing and is suitable for structural improvement of similar products.

Detailed Description
The construction and use of the utility model will now be further described with reference to the accompanying drawings. As shown in fig. 1-3, the waist drum bearing comprises an outer ring seat 1 and an inner ring 2, wherein triangular extension edges symmetrically arranged at two ends of the outer ring seat are respectively provided with an installation screw hole 101, a central ring hole of the outer ring seat protrudes towards the top, steel balls 3 are distributed between the central ring hole of the outer ring seat and the outer diameter of the inner ring at equal intervals, the steel balls are provided with retainers, and annular ring grooves at two sides of the steel balls are provided with dust covers. The opening of the inner ring is higher than the central hole of the outer ring seat, at least one side of the inner ring higher than the opening of the outer ring seat is provided with a transverse screw hole 201, and a single row or double rows of steel balls are arranged between the central hole of the outer ring seat and the outer diameter of the inner ring.
When the waist drum bearing is used, the waist drum bearing is arranged on equipment through the fixing and mounting hole, the inner ring is inserted into the shaft part, and the shaft part can be fixed on the inner ring through the transverse screw hole according to requirements.
To sum up, this bearing includes that waist drum-type outer lane two firm ends set up two installation screw holes, and one of them plane sets up thickening step and seal groove on two planes, and another plane sets up the seal groove, sets up single row or double steel ball slot in the hole. One end of the inner ring is provided with two transverse screw holes, the other end of the inner ring is provided with two sealing grooves, a single-row or double-row steel ball groove is arranged between the two sealing grooves, and a steel ball, a retainer and a sealing ring are arranged between the inner ring and the outer ring. Therefore, the waist drum bearing can directly mount the steel ball on the waist drum shell and the connecting sleeve by detaching and recombining the shell and the bearing of the same kind of products, thereby stabilizing the mounting precision and the combination precision and ensuring the stable operation of machinery.
