Description

Novel bearing with windshield Technical Field The utility model relates to the technical field of bearings, in particular to a novel bearing with a windshield. Background The bearing is a key component in the machine and is used for determining the relative movement position of the rotating shaft and other parts, and the quality of the bearing directly influences the working performance of the whole machine. In order to prevent dust and other pollutants from entering the inside of the bearing and sealing lubricating oil, the use effect and the service life of the bearing are improved, and a sealing mechanism is usually arranged between the inner ring and the outer ring of the bearing. The existing outer spherical ball bearing for the fan with the seat has the defects that the sealing mode has obvious defects in a high wind speed environment and is not ideal in effect, and oil dirt and dust enter a bearing chamber due to too large wind force, while the traditional bearing has some protective measures, more bearings adopt rubber lips as sealing mechanisms, so that the bearing is in early failure. Disclosure of utility model The utility model aims to provide a novel bearing with a windshield, so as to solve the problems in the background art. The novel bearing with the windshield comprises a vertical bearing seat, a windshield cover and an end cover, wherein a plurality of bolts are arranged on the outer ring of the windshield cover and the outer ring of the end cover, the windshield cover is fixedly arranged at one end of the vertical bearing seat through the bolts, the end cover is fixedly arranged at the other end of the vertical bearing seat through the bolts, a bearing outer ring and two windshields positioned at two ends of the bearing outer ring are fixedly arranged in the vertical bearing seat, a bearing inner ring is arranged on the inner side of the bearing outer ring, a mandrel is arranged in the bearing inner ring, two sealing rings and a plurality of steel balls positioned between the two sealing rings are arranged between the bearing outer ring and the bearing inner ring, one opposite sides of the two windshields are respectively connected with one sides of the two sealing rings, and the windproof and dustproof functions of the fan bearing are improved. Preferably, the two windshields are both annular and concentric with the center hole of the bearing inner ring. Preferably, two retainers are arranged between the bearing outer ring and the bearing inner ring, the two retainers are positioned on two sides of the plurality of steel balls, the plurality of steel balls are clamped by the two retainers from two ends, the plurality of steel balls are limited and fixed, and the stability of the plurality of steel balls is improved. Preferably, the two sealing rings are respectively positioned at the opening of the gap between the bearing outer ring and the bearing inner ring, and the two sealing rings seal the gap between the bearing outer ring and the bearing inner ring from two ends. Preferably, the two windshields are sleeved on the bearing inner ring, the two windshields are connected with one side of the two sealing rings, which is away from the two sealing rings, in a contact way, the windshields play a role in wind shielding, and dust and oil stains are prevented from being blown into the bearing seal. Preferably, the mandrel passes through the middle part of the windproof cover and extends to the outside, and a windproof sealing ring is fixedly arranged at the joint of the windproof cover and the mandrel and seals the joint of the windproof cover and the mandrel. Compared with the prior art, the utility model has the beneficial effects that the additional wind-proof device can thoroughly prevent oil dirt and dust blown in by strong wind from entering the bearing chamber, and prevent early failure of the bearing caused by dust and oil dirt blown in by the bearing seal, thereby prolonging the service life of the bearing.
