Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a novel sealed backing bearing. Background Technique

[0002] In the prior art, the installation between the bearing and the shaft is roughly as follows: the inner ring of the bearing is sleeved on the shaft, and then a clamping groove is formed in the bearing, and a snap ring is clamped in the clamping groove to limit the axial movement of the inner ring. Or, by arranging locking nuts at both ends of the rotating shaft to limit the position of the inner ring of the bearing; when installing the backing bearing on the backing support shaft with the conventional bearing installation method, it is necessary to sleeve the backing bearings one by one onto the backing support shaft. After a predetermined number of backing bearings are all sleeved, then clamp and fix them at both ends of the backing support shaft. With the conventional installation method, the backing support shaft cannot shake at all. Once it shakes, more than a dozen backing bearings will slide off and need to be reinstalled, resulting in a relatively cumbersome and inconvenient overall installation process of the bearing and affecting the efficiency. For this reason, we propose a novel sealed backing bearing. Content of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a novel sealed backing bearing.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solution: a novel sealed backing bearing, including a bearing outer lining and a bearing inner lining. An embedding groove is formed in the periphery of the bearing inner lining, and bearing balls are clamped in the embedding groove. A packaging groove communicating with the inside of the bearing outer lining is formed in the end face of the bearing outer lining, and a packaging shaft sleeve that is packaged and matched with the packaging groove is arranged inside the packaging groove.

[0005] Preferably, the bearing inner lining is in rolling support cooperation with the inner side of the bearing outer lining through the bearing balls in the embedding groove, and the bearing balls inside the bearing inner lining can be in a directly inserted installation state inside the bearing outer lining through the packaging groove.

[0006] Preferably, an external thread is formed on the periphery of the packaging shaft sleeve, an internal thread is formed on the inner side of the packaging groove, a sealing gasket is coated on the surface of the external thread, and the sealing gasket has a deformation characteristic. The packaging shaft sleeve is in threaded connection and cooperation with the internal thread on the inner side of the packaging groove through the external thread.

[0007] Furthermore, when the external thread on the periphery of the packaging shaft sleeve is in threaded connection with the internal thread on the inner side of the packaging groove, the sealing gasket on the surface of the external thread is in a state of being threadedly engaged through the external thread and the internal thread.

[0008] Preferably, a spherical groove is provided on one side of the packaging sleeve and the inner side of the bearing outer liner, and a limit ball is movably engaged inside the spherical groove. Both ends of the bearing inner liner are provided with a docking groove, and the docking groove is an annular groove body;

[0009] Furthermore, when the bearing liner is inserted into the bearing outer liner, the limiting ball on the inner side of the bearing outer liner is in a limited sliding fit with the docking groove at one end of the bearing liner, and when the packaging sleeve is docked with the inside of the packaging groove, the limiting ball on one side of the packaging sleeve is in a limited sliding fit with the docking groove at the other end of the bearing liner.

[0010] Beneficial Effects

[0011] The utility model provides a new type of sealed backing bearing, which has the following beneficial effects:

[0012] 1. A new type of sealed backing bearing. In this article, when assembling the bearing, multiple groups of bearing balls can be first embedded in the embedding groove inside the bearing liner. At this time, the assembled bearing liner and bearing balls can be directly horizontally inserted into the bearing outer liner through the packaging groove for docking. There is no need to stack multiple groups of bearing balls in sequence as in the traditional way. After the bearing liner and the embedding groove are inserted into the bearing outer liner, the packaging sleeve can be connected and matched with the internal thread on the inner side of the packaging groove through the external thread. In this way, the bearing as a whole can be quickly disassembled and assembled, thereby achieving the effect of improving the efficiency of bearing disassembly and assembly.

[0013] 2. A new type of sealed backing bearing, after the bearing liner and multiple groups of bearing balls are docked and installed with the inside of the bearing outer liner, they can be connected and matched with the internal threads on the inner side of the packaging groove through the external threads on the outer periphery of the packaging sleeve, and the sealing gasket on the surface of the external thread can cooperate with the external thread and the internal thread to bite and seal each other, thereby improving the internal sealing effect of the bearing outer liner.

[0014] 3. A new type of sealed backing bearing, wherein a spherical groove is provided on one side of the packaging sleeve and one side inside the bearing liner, and a limit ball is movably engaged inside the spherical groove. When the bearing liner is inserted into the bearing liner, the docking groove at one end of the bearing liner can be docked with the limit ball on the inner side of the bearing liner. After the packaging sleeve is docked and installed with the inside of the packaging groove, the limit ball on one side of the packaging sleeve can be docked with the docking groove at the other end of the bearing liner. At this time, when the bearing liner is located inside the bearing liner and rotates, the two ends of the bearing liner can be slidably limited by the limit balls, thereby achieving the effect of ensuring the rotation stability of the bearing liner located inside the bearing liner.
