Bearing sealing device

Abstract

The invention discloses a bearing sealing device. The device comprises a main shaft and a rotating shaft, and bearing blocks are fixedly connected to both the upper side and the lower side of the leftend of the rotating shaft; bearing end covers are fixedly connected to both the upper side and the lower side of the right end of each bearing block, and self-tapping screws are installed on both theleft side and the right side in each bearing end cover; an annular groove is formed in the upper surface of the left side of the rotating shaft, and floating sealing rings are arranged on both the upper side and the lower side in the annular groove; the main shaft is fixedly connected among the self-tapping screws, the main shaft is fixedly arranged on the lower surface of the rotating shaft, anda U-shaped sealing ring is fixedly connected to the upper surface between the main shaft and the rotating shaft; and a bearing inner cover is arranged at the lower end of the U-shaped sealing ring, abearing rod is fixedly connected to the lower end of the bearing inner cover, and oil injection holes are formed in the left side and the right side of the U-shaped sealing ring. The bearing sealingdevice has the advantages of being reasonable and simple in structural design, high in practicability, excellent in sealing effect, compact in structure and convenient to install, so that popularization and use are facilitated.

Description

technical field [0001] The invention belongs to the technical field of sealing devices, and in particular relates to a bearing sealing device. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. It can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the shaft fixed. The purpose of the bearing seal is to prevent the leakage of lubricating oil in the bearing part, and to prevent the external dust, moisture, foreign matter and other harmful objects from invading the inside of the bearing, so that the bearing can operate safely and permanently under the required conditions. [0003] However, the current bearing sealing device still has some shortcomings and deficiencies in some aspects, such as: the sealing effect of the sealing device is not good, and the le...

Problems solved by technology

[0003] However, the current bearing sealing device still has some shortcomings and deficiencies in some aspects, such as: the sealing effect of the sealing device is not good, and the leakage of lubricating oil is prone to cause pollution, and the structure of the device is not compact enough, which also leads to poor sealing. Therefore seek a kind of bearing sealing device to become the problem that main solution at present
