Technical Field

[0001] The utility model belongs to the technical field of bearing maintenance, in particular to a cylindrical roller bearing with an outer ring end face having an oil hole. Background Art

[0002] Bearings are a key mechanical component in modern industrial production and are widely used in various mechanical equipment. Cylindrical roller bearings play an important role in many fields due to their high load-bearing capacity, high rotation accuracy, and low friction coefficient.

[0003] However, during the use of cylindrical roller bearings, lubrication and protection issues have always been key factors affecting their performance and life. Cylindrical roller bearings are difficult to lubricate, maintain, and add oil, and cannot be maintained in a timely and effective manner. At the same time, in harsh working environments, impurities such as dust and moisture can easily invade the interior of the bearing, causing serious impact on the normal operation of the bearing and reducing the service life and reliability of the bearing. For this reason, it is necessary to provide a cylindrical roller bearing with an oil hole on the outer ring end face, which can not only facilitate the addition of oil and achieve timely maintenance of the bearing, but also prevent dust and moisture from invading through an effective sealing device, thereby providing good protection for the bearing. Utility Model Content

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model provides an oil filling hole to add oil between the outer ring and the inner ring, thereby maintaining the cylindrical roller. At the same time, the oil filling hole can be blocked or opened by cooperating with the rotating ring and the sealing assembly, thereby providing dustproof and waterproof protection for the inner cavity of the outer ring, thereby achieving the purpose of facilitating maintenance and effectively preventing dust and water;

[0020] Hereinafter, embodiments of a cylindrical roller bearing with an outer ring end surface having an oil hole according to the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4A cylindrical roller bearing with an oil hole on the outer ring end face of an embodiment of the utility model is shown, comprising an outer ring 1: an inner ring 2 is provided in the inner cavity of the outer ring 1, a plurality of rotatable cylindrical rollers 8 are distributed annularly between the outer ring 1 and the inner ring 2, a plurality of oil filling holes 3 are annularly opened on the front side of the outer ring 1, a limiting ring 4 is fixedly connected to the front side of the outer ring 1, a rotating ring 5 is rotatably connected to the surface of the limiting ring 4, a sealing component 6 is provided on the front side of the outer ring 1, the sealing component 6 includes a sealing plate 61 annularly fixedly connected to the inner cavity of the rotating ring 5, a rubber plug 62 is fixedly connected to the rear side of the sealing plate 61, the rubber plug 62 is pressed into the inner cavity of the oil filling hole 3, a fixing ring 63 is fixedly connected to the edge of the front side of the outer ring 1, a plurality of damping plates 64 are fixedly connected to the inner wall of the fixing ring 63, and a plurality of damping plates 64 are fixedly connected to the inner wall of the rotating ring The surface of 5 is provided with a plurality of limit slots 65 adapted to the damping plate 64. The damping plate 64 is an elastic spring, which is engaged in the inner cavity of the limit slot 65. Through the setting of the sealing component 6, the sealing plate 61 and the rubber plug 62 are used in combination to seal the oil filling hole 3, so that when no oil is added, the interior of the outer ring 1 is shielded and protected to prevent dust from invading. At the same time, with the cooperation of the fixing ring 63, the damping plate 64 and the limit slot 65, the rotating ring 5 is damped and limited, so that the rubber plug 62 can be stably engaged in the inner cavity of the oil filling hole 3, thereby improving the reliability of the rubber plug 62 when sealing the oil filling hole 3. The top and bottom of the front side of the rotating ring 5 are fixedly connected with the toggle block 7.

[0022] Working principle: When the utility model is used, the user rotates the rotating ring 5 by turning the block 7. The rotating ring 5 drives the sealing plate 61 to rotate during the rotation. The sealing plate 61 drives the rubber plug 62 to separate from the inner cavity of the oil filling hole 3 during the rotation. At this time, the oil filling hole 3 remains open. The user can fill the oil between the outer ring 1 and the inner ring 2 through the oil filling hole 3 to lubricate and maintain the cylindrical roller 8 in the inner cavity of the outer ring 1. After maintenance, the user rotates the toggle block 7 in the opposite direction to make the rotating ring 5 and the sealing plate 6 1 rotates in the opposite direction, so that the rubber plug 62 is re-engaged in the inner cavity of the oil filling hole 3 to block the oil filling hole 3. During the rotation of the rotating ring 5, the limiting groove 65 repeatedly squeezes and toggles the damping plate 64, causing the damping plate 64 to deform. After the rotating ring 5 stops rotating, the damping plate 64 is engaged in the inner cavity of the current limiting groove 65 to limit the rotating ring 5. At the same time, the sealing plate 61 and the rubber plug 62 are limited, so that the rubber plug 62 can be stably engaged in the inner cavity of the oil filling hole 3.

[0023] In summary, the cylindrical roller bearing with an oil hole on the outer ring end face can add oil between the outer ring 1 and the inner ring 2 through the setting of the oil filling hole 3, so as to maintain the cylindrical roller 8. At the same time, the oil filling hole 3 can be blocked or opened by the coordinated use of the rotating ring 5 and the sealing assembly 6, thereby providing dustproof and waterproof protection for the inner cavity of the outer ring 1, thereby achieving the purpose of facilitating maintenance and effectively preventing dust and water.
