Description

Novel bearing lubrication device

Technical Field

The utility model belongs to the technical field of the lubricated technique of bearing and specifically relates to a novel bearing is lubricated device.

Background

The bearing means a member for fixing and reducing a friction coefficient of a load during a mechanical transmission, and also means a member for reducing a friction coefficient during a power transmission and keeping a center position of a shaft fixed when other members relatively move with each other on the shaft, as it is. The bearing is a lightweight part in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load of equipment in the transmission process.

In either a rolling bearing or a sliding bearing, when the shaft rotates, the rotating part and the static part of the shaft cannot be in direct contact, otherwise the shaft can be damaged due to friction. In order to prevent friction of the dynamic and static portions, a lubricant must be added. The action of the lubricant on the bearing mainly shows three aspects of lubrication action, cooling action and cleaning action. The leakage condition always appears in hot rolling mill bearing lubrication on the existing market, and the cooling effect of the bearing is very poor. When the leakage phenomenon occurs, the sealing device is mainly covered tightly by a simple gland, the effect is general, and the shaft head is abraded. The cooling effect of the bearing is poor, and the bearing is damaged.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a novel bearing lubricating device, which comprises a gland, a filler, a bearing cover, two oil slingers and a bearing seat, wherein the two oil slingers are respectively arranged at two sides of the bearing; the bearing cover is internally provided with an annular oil duct which is uniformly distributed along the axial direction of the oil retainer body; a first chamber, a second chamber and a third chamber are sequentially arranged in the bearing cover, and the three chambers are communicated; the bearing is arranged in the second chamber; oil return holes are formed below the first bin and the third bin; and an oil retaining groove penetrating through the annular oil duct is formed in the inner wall of the second chamber, and the oil retaining groove is formed by distributing guide grooves formed in the bottom of the annular oil duct along the axial direction.

Further, the inner surface of the slinger is provided with a plurality of small holes for introducing or discharging oil.

Further, the oil retaining groove is formed by a plurality of guide grooves which are distributed at intervals along the axial direction of the oil retaining ring body.

Furthermore, the outer wall of the oil retainer is uniformly distributed with radiating fins along the axial direction, and the radiating fins are provided with radiating holes which are uniformly distributed.

Further, the slinger is integrally formed.

The utility model discloses increase two oil slingers on bearing both sides, through the oil slinger when lubricating oil flows from the bearing, the oil slinger that is driven by the high-speed rotation of spindle nose throws away, through the bottom oil gallery, directly returns and falls. The other part of lubricating oil flows through an oil blocking groove of the shaft end vehicle and is directly thrown out by the high-speed rotation of the shaft end, and the internal annular oil passage of the bearing cover is designed, so that the oil is not accumulated at the bottom and directly returns through an oil return hole at the bottom, the rapid circulating cooling of the bearing is realized, the overheating abrasion of the bearing is effectively avoided, and the lubricating oil is quickly and effectively returned out at the bottom. Because the oil flowing through the shaft end is little, the leakage (filling) is not tightly pressed, and the abrasion to the shaft end is effectively avoided.
