Detailed Description

A bearing body capable of dissipating heat comprises an upper bearing body 110 and a lower bearing body 120, wherein the upper bearing body 110 and the lower bearing body 120 are folded to form a shaft hole for a shaft 130 to pass through, a bearing 140 is positioned in the shaft hole and sleeved on the shaft 130, a lock nut is arranged between an inner ring of the bearing 140 and the shaft, a heat dissipation fin 150 is arranged on the upper bearing body 110 and/or the lower bearing body 120, and the heat dissipation fin 150 is flaky and is vertically arranged on the upper bearing body 110 and/or the lower bearing body 120. Alternatively, the heat dissipation fins 150 may be disposed on the upper bearing body 110, the heat dissipation fins 150 may be disposed on the lower bearing body 120, or the heat dissipation fins 150 may be disposed on both the upper bearing body 110 and the lower bearing body 120. Since the bearings 140 are lubricated and cooled by the lubricant, heat generated by the rotation of the bearings 140 is transferred to the lubricant, which in turn transfers the heat to the bearing bodies. The heat can be exchanged with the surrounding environment through the radiating fins on the bearing body, and the contact area between the radiating fins 150 arranged vertically and the air is large, so that the heat in the bearing body can be efficiently discharged, the radiating effect is good, and the speed is high.

The lower bearing body 120 is provided with an oil chamber for storing lubricating oil therein. The bearings 140 are lubricated and cooled by using lubricating oil, and most of heat generated by the operation of the bearings 140 is transferred into the lubricating oil, so that the bearings are cooled.

The lower bearing body 120 is provided with heat dissipation fins 150, and the heat dissipation fins 150 are uniformly distributed along the circumferential direction of the lower bearing body 120 at intervals.

An oil chamber is provided in the lower bearing body 120, and most of the lubricating oil is stored in the bottom of the lower bearing body 120, that is, most of the heat generated by the bearing 140 is accumulated therein. Therefore, the utility model discloses set up fin 150 in the below of lower bearing body 120, be equivalent to the area of contact of bearing body 120 and air under the increase to quick direct heat is arranged the bearing body outside in with lubricating oil. The heat collected in the lubricating oil is avoided, so that the purpose of rapidly and timely cooling the bearing is achieved, and the cooling effect is greatly improved

The heat dissipation fins 150 are arranged along the axial direction of the lower bearing body 120 in the longitudinal direction.

The heat dissipation fins 150 extend to the two ends of the lower bearing body 120 in the axial direction toward the two sides in the length direction. The utility model provides a fin 150 is rectangular flat slice, and connects the both ends of bearing body 120 under, and this structure forms a complete power transmission route, on bearing body 120 was transferred to the load that bears on the bearing that also says so, then through the both ends of bearing body 120 under the fin 150 dispersion, transmit to the equipment frame on then. It can be seen that the heat sink 150 acts as a rib, and increases the strength of the bearing body while dissipating heat.

The number of the heat dissipation fins 150 is two or more.

A bearing pad 160 is disposed between the outer ring of the bearing 140 and the bearing body, and a bearing end cover 170 covers an end surface of the outer ring of the bearing 140 and is fixed to the upper bearing body 110.

The heat sink 150 and the lower bearing body 120 are integrally cast. The structure formed by integral casting is easy to process, low in cost and high in strength.

A framework oil seal 180 is arranged between the bearing end cover 170 and the shaft 130.

The heat dissipation fins 150 are evenly provided with 6 to 8 fins at intervals along the circumferential direction of the lower bearing body 120. The number of the heat dissipation fins 150 is determined by the lower bearing body 120, which not only increases the heat dissipation area, but also cannot be too dense, and the heat dissipation effect is very good as the use requirements can be met by the design of 6-8.

Bearing 140 is through the lubricated cooling of lubricating oil, and in the heat transfer to the lubricating oil of the rotatory production of bearing, lubricating oil is again to these heat transfer to the bearing body on, just so can exchange the heat through fin and surrounding environment on the bearing body, realize the efficient with the heat discharge of the internal portion of bearing, the radiating effect is good, fast. And meanwhile, additional parts are not added, the size of the bearing body is not increased, and the bearing is low in cost, easy to machine and easy to realize.
