Description

Technical Field

[0001] The present application relates to the technical field of bearings, and in particular to an impact-resistant deep groove ball bearing. Background Art

[0002] Bearings are widely used in mechanical rotating equipment, and are classified into ball bearings, needle roller bearings, etc. Among them, ball bearings are the most commonly used bearing type, and deep groove ball bearings are the most commonly used rolling bearings. They have a simple structure and are easy to use. They are mainly used to bear radial loads and are now widely used.

[0003] In the patent with the published authorization announcement number CN201593555U, the deep groove ball bearing belongs to the field of mechanical technology. It solves the problems of the existing deep groove ball bearings that are not impact-resistant and have poor load-bearing capacity. The deep groove ball bearing includes a bearing inner ring, a bearing outer ring and a spherical ball with a retainer. A raceway is provided between the bearing inner ring and the bearing outer ring and the above-mentioned ball is located in the raceway. The bearing outer ring has an upper concave arc groove, the bearing inner ring has a lower concave arc groove, and the upper concave arc groove and the lower concave arc groove are positioned relative to each other to form a ball adding port. The deep groove ball bearing has the advantages of simple structure, good use effect and strong load-bearing capacity.

[0004] When the above device is implemented, the number of balls is increased without increasing the size of the overall bearing by adding a ball adding port, thereby enhancing its radial load-bearing capacity. However, the above device cannot seal the ball adding port, which causes the balls to easily fall off when the device is installed on the equipment for operation, and foreign impurities can easily enter the middle position between the outer ring and the inner ring of the bearing through the ball adding port, resulting in restricted rolling of the balls, which in turn affects the normal operation of the device.

[0016] By adopting the above technical solution, the upper and lower sides of the ball can be protected, ensuring that foreign matter will not be stuck in the middle position of the ball after the device is installed on the equipment.

[0017] As a preferred embodiment, the number of the blocking columns is two, and the two blocking columns are respectively arranged on the inner wall of the ball adding port on the inner side of the outer ring and the outer side of the inner ring.
