Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a high-speed and heavy-load bearing seat. Background Art

[0002] Due to the structural characteristics of rolling bearings, their rollers will generate friction with the inner and outer rings and release heat during operation. The uneven heat generation and dissipation cause temperature differences between the rollers, inner rings and outer rings of the rolling bearings, resulting in different degrees of expansion of the rollers, inner rings and outer rings. The inner ring has the highest temperature and expands most seriously, followed by the rollers, and the outer ring has the smallest temperature. For high-speed and heavy-load bearing seats, the temperature difference between the inside and outside is more serious due to the large diameter of the bearings used, the large load they bear and the high speed. This will lead to a decrease in the radial clearance of the rolling bearing and an increase in friction.

[0003] The patent with application number 202120765233.6 discloses a sliding bearing seat, which relates to the technical field of bearing seats. The utility model includes an installation mechanism, a sliding device, a main device, a fixing device, a water cooling device and an adjusting device. The installation mechanism includes a mounting base, the sliding device includes a slide rail and a slide groove, the main device includes a bearing seat body and an upper bearing shell, the lower surface of the bearing seat body is welded to the upper surface of the slide rail, the fixing device includes a bearing cover and a fixing screw, the water cooling device includes a sealing ring and a water channel, the inner surfaces of several sealing rings are connected to the outer surface of the bearing seat body, the outer surfaces of several water channels are welded to the inner surface of the bearing seat body, and the adjusting device includes an adjusting screw.

[0004] The above technical solution utilizes the water circulation mechanism on the outside of the bearing seat to dissipate heat from the bearing. However, since the water circulation mechanism can only dissipate heat from the outside of the bearing where the temperature is lower, the temperature difference inside the bearing is aggravated, resulting in a decrease in the radial clearance of the rolling bearing and an increase in friction. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and to provide a high-speed and heavy-load bearing seat, which realizes the function of uniform heat dissipation of the bearing by wind and circulating lubricating oil through a wind mechanism in conjunction with a circulation structure and a heat dissipation box structure, thereby solving the problem of reduced radial clearance and increased friction of the rolling bearing caused by excessive temperature difference between the inside and outside of the bearing.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed and heavy-load bearing seat, comprising a base and a fastening frame fixed to the top of the base, wherein a bearing body is symmetrically fixed in the base, and heat dissipation grooves are provided on both sides of the base, and the bottom walls of the two heat dissipation grooves are provided with mounting grooves, and a cooling box is embedded in the mounting grooves, a heat sink is fixed on the top of the cooling box, and a circulation mechanism connected to the bearing body is provided on the cooling box, and a wind mechanism is bonded to the inner walls of the two bearing bodies.

[0007] Preferably, the wind power mechanism comprises a mounting ring fixed to a side wall of a rotor of a bearing body and wind blades fixed to the side wall of the mounting ring in an annular array.

[0008] Furthermore, a lubrication cavity is provided at the center of the bearing body, and balls are embedded in the lubrication cavity in a ring array.

[0009] Furthermore, a micro water pump is embedded and fixed at the bottom end of the base, and the circulation mechanism includes a circulation pipe fixed at both ends of the micro water pump and a delivery pipe fixed at both ends of the two cooling boxes.

[0010] Furthermore, the two circulation pipes are respectively connected to the bottom ends of the two cooling boxes, the delivery pipes at both ends of the two cooling boxes are respectively connected to the lubrication chambers on both sides of the two bearing bodies, and a heat dissipation chamber connected to the heat dissipation groove is arranged between the two bearing bodies.

[0011] Furthermore, both ends of the bearing body are provided with oil seals embedded and fixed in the base, and both ends of the base are provided with mounting holes.

[0012] Furthermore, screw holes are symmetrically provided on both sides of the top surface of the base, and bolts threadedly inserted into the screw holes are provided on the top of the fastening frame.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model has heat dissipation grooves at both ends of the base and a mounting ring fixed on the inner wall of the bearing body. The interior of the bearing rotates synchronously with the shaft body, thereby driving the mounting ring and the wind blades to rotate synchronously. During the rotation, air flows between the two heat dissipation grooves, and during the flow, the inner and outer sides of the bearing are cooled at the same time, thereby improving the heat dissipation effect of the bearing.

[0015] (2) The utility model provides an installation groove on the bottom wall of the heat dissipation groove, in which a cooling box is embedded and fixed, and a heat sink embedded in the heat dissipation groove is provided on the top of the cooling box.

The lubricating oil is used for heat dissipation and heat conduction, which greatly reduces the problem of reduced radial clearance and increased friction of the rolling bearing caused by excessive temperature difference between the various parts of the bearing.
