Description

Technical Field

[0001] The invention relates to the technical field of deep groove ball bearings, in particular to a precision heavy-load deep groove ball bearing. Background Art

[0002] In heavy-load environments, in order to ensure the accuracy and stability of the equipment, precision heavy-load deep groove ball bearings are usually used for high-precision positioning to adapt to complex load conditions. Existing precision heavy-load deep groove ball bearings are usually composed of a bearing inner ring, bearing balls, a bearing outer ring and a bearing cage.

[0003] For example: the utility model with application number CN202020848886.6 discloses a deep groove ball bearing that can bear heavy axial loads, specifically including an outer ring, an inner ring and a plurality of symmetrically arranged rolling elements, the inner ring is located inside the outer ring, the plurality of rolling elements are located between the inner ring and the outer ring, and the upper and lower ends are both in contact with a retainer, the two retainers are tightly connected by a plurality of rivets, the inner and outer rings are both provided with an annular groove on one side close to the upper and lower ends, the groove walls of the two grooves are provided with an annular groove, the two grooves are in contact with a dustproof plate, the two dustproof plates are provided with a clamping mechanism on both sides, the two retainers are provided with a connection hole inside and on the right side of the rivet, and a reinforcement mechanism is provided in the connection hole. The utility model can reinforce the retainer in the bearing to prevent the rivet from breaking when the axial force is too large, resulting in damage to the retainer and the bearing.

[0004] However, during the use of precision heavy-loaded deep groove ball bearings, due to the heavy load conditions, the bearings are subjected to a large load and the contact pressure between the bearing balls and the inner and outer rings is also very large. In order to reduce fatigue wear between the bearing balls and the inner and outer rings, workers are usually required to apply grease to the bearings regularly, which is a cumbersome operation. At the same time, frequent maintenance operations also increase downtime, making it inconvenient to use. Summary of the invention

[0005] In view of this, the present invention provides a precision heavy-loaded deep groove ball bearing, which has a grease outlet groove and a sealing baffle that can automatically flow out grease to lubricate the bearing. During the rotation of the bearing retainer, the control push frame will be driven to rotate. As the control push frame rotates, it will slowly contact the control slide plate, so that the control push frame squeezes the control slide plate, and the control slide plate slides in the outer ring body of the bearing. During the sliding of the control slide plate, the connecting slide plate will be driven to slide in the connecting slide groove to provide guidance for the control slide plate. As the control slide plate slides, the fixed spring will be squeezed. In the initial state, the control protrusion will squeeze the control roller, so that the sealing baffle is closed to seal the grease outlet groove. As the control slide plate moves, the control protrusion will be driven to move. As the control protrusion moves, the fixed plate will drive the sealing baffle to slowly open, so that the grease in the grease storage groove flows out to lubricate the bearing balls.

When the dustproof ring needs to be replaced, the control slide is pulled, and then the connecting bracket is driven to move and squeeze the connecting spring through a series of transmissions. As the connecting bracket moves, the clamping connection with the fixed block is released, and the staff can remove the dustproof ring at this time. The operation is simple and quick, which effectively improves the convenience of the deep groove ball bearing. BRIEF DESCRIPTION OF THE DRAWINGS
