Problems solved by technology

However, ordinary bearings are immersed in a small amount of lubricating oil when they leave the factory (because there is no oil storage structure), which will be consumed quickly during use. When the lubricating oil is lost, the bearing will be damaged soon. In order to solve this problem, we Developed a linear motion ball bearing that can continuously replenish lubricating oil, which not only improves the working accuracy of the bearing, but also prolongs the life of the bearing

Embodiment

[0024] first see attached figure 1 , is a linear bearing in the prior art, including an outer ring 11, balls 12 and a cage 13 arranged inside, and sealing rings 14 are respectively arranged at both ends of the outer ring 11. When the upper shaft is matched, the ball 12 and the shaft The rolling friction between the sealing ring 14 and the shaft is sealed and slipped to prevent dust from entering the outer ring 11. Because there is no oil storage structure in this setting method, only a small amount of lubricating oil is immersed in the bearing, which will be consumed quickly during use. When the lubricating oil is lost, the bearing will be damaged soon.

[0025] In this embodiment, for the linear bearing with the oil storage tank 3, refer to the attached Figure 2-8 , the linear bearing still includes the outer ring 21, as well as the balls 22 and the cage 23 arranged therein, and oil storage tanks 3 are respectively arranged at both ends of the outer ring 21. The side of th...

Abstract

The invention discloses a linear bearing with oil storage cabins. The linear bearing comprises an outer ring, a ball arranged in the outer ring and a retaining rack. The circular oil storage cabins with oil storage cavities are separately arranged at two ends of the outer ring, clamping mechanisms detachably connected to the outer ring are arranged on the sides, opposite to the outer ring, of theoil storage cavities, the oil storage cabins are formed in the sides, far away from the outer ring, of the oil storage cabins, the oil storage cavities on the side deviated from the outer ring are infit clamping to seal rings, and when the oil storage cabins are matched with the seal rings, an oil via hole is formed in the direction of center of circle, toward the oil storage cabins, of the oil storage cavities in a conducting manner. By arranging the oil storage cabins, the oil storage capability of the bearing is improved and the linear bearing is convenient to detach and mount.

Description

technical field [0001] The invention relates to the field of linear bearings, in particular to a linear bearing with an oil storage tank. Background technique [0002] With the continuous increase of mechanical automation production lines, precision transmission components are more widely used, and at the same time, the requirements for the precision and service life of rolling bearings are higher. When the rolling bearing is working, the rolling friction between the steel ball and the raceway must have lubricating oil to form a lubricating film between the steel ball and the raceway to avoid direct contact between the steel ball and the raceway, otherwise the steel ball and the raceway surface will form a Sliding friction, the contact point of the working surface is under the action of load, causing it to wear rapidly, causing fatigue spalling and shortening the service life of the bearing. However, ordinary bearings are immersed in a small amount of lubricating oil when t...
