Abstract

The utility model relates to a split self-aligning roller bearing, which comprises a bearing outer ring, a bearing inner ring, rollers and a retaining frame. The bearing outer ring and the bearing inner ring are both radial split structures and consist of two semi-rings respectively, peripheral surfaces at two ends of the bearing inner ring are both provided with ring slots, and clamps fixing the two semi-rings of the bearing inner ring are arranged inside the ring slots. The retaining frame is an axial split structure, two portions of the retaining frame are connected via a strut, and the rollers are waist-drum-shaped rollers in single row. The bearing outer ring and the bearing inner ring consist of two semi-rings respectively and are easy for mounting, dismounting, cleaning and maintaining, thereby being capable of effectively reducing time for maintenance of the bearing.

Description

A kind of subdivision selfaligning roller bearing

Technical field

The utility model relates to a kind of subdivision selfaligning roller bearing.

Background technique

On the pebble mill of cement industry; require bearing the bearing capacity height, be easy to install, shut down maintenance time short; owing to enter dust easily in the bearing of the special pebble mill of working environment; need often to shut down maintenance and carry out preventive maintenance, this just requires bearing to be easy to disassemble installation to shorten the time of maintenance.In addition, factor such as the installation position of adding bearing is narrow, the spatial position is limited, the time that traditional double-row self-aligning roller bearing is used when shutting down maintenance, installing/dismounting is just longer, can't reduce maintenance downtime to greatest extent.Traditional double-row self-aligning roller bearing also can't reach the performance requirement to high bearing capacity of main frame simultaneously.

The model utility content

The purpose of this utility model provides a kind of subdivision selfaligning roller bearing, the used time of installing/dismounting when overhauling to shorten bearing.

For achieving the above object, the utility model adopts following technological scheme: a kind of subdivision selfaligning roller bearing, comprise bearing outer ring, bearing inner race, roller and retainer, described bearing outer ring and bearing inner race are radially split-type structural, form by two half-turns, be provided with annular groove on the side face at described bearing inner race two ends, be provided with two clips that half-turn is fixed together in this annular groove bearing inner race.

Described retainer is axially to divide body structure, and two-part of retainer are connected by pillar, and described roller is single-row waist drum type roller.

One end of described pillar is provided with screw thread, the end face of the other end is provided with screwdriver slot, the lintel of the retainer that cooperates with roller one end part is provided with the tapped hole that cooperates with the threaded end of pillar, and the retainer that cooperates with roller the other end lintel partly is provided with screwdriver slot with pillar and is provided with and holds adaptive through hole.

Bearing outer ring of the present utility model and bearing inner race are formed by two half-turns, and two half-turns of bearing inner race are fixed together by clip, are easy to installation, dismounting, cleaning maintenance, can effectively reduce the bearing used time in when maintenance.

Because retainer of the present utility model is axially to divide body structure, two-part retainer is connected by pillar, and the intermediate portion of waist drum type roller does not just have retainer so, so just can increase the quantity of roller effectively, improves the bearing capacity of bearing.In addition, roller of the present utility model is single-row, can adapt to the narrow occasion in Bearing Installation position.
