Embodiment Construction
[0021] In the rolling bearing heat dissipation method provided by the present invention, the main shaft 14 and the rolling bearing 12 are correspondingly installed in the bearing hole of the bearing seat, and the outer cylindrical surface of the rolling bearing outer ring and the matching section 300 on the inner wall surface of the bearing hole of the bearing seat are correspondingly tightly fitted. , the cooling groove on the inner wall surface of the bearing hole and the outer cylindrical surface of the rolling bearing outer ring form a cooling pipeline 100. When the main shaft 14 drives the bearing inner ring and the rollers to rotate, the cooling fluid is injected into the cooling pipeline under high pressure, and the cooling fluid Enter the cooling pipe 100 and output from the fluid output channel. When the cooling fluid flows in the cooling pipe 100, the cooling fluid flowing through the cooling pipe 100 exchanges heat with the outer ring of the bearing to realize heat di...

The invention discloses a rolling bearing radiating device, which comprises a bearing block. The bearing block is provided with a bearing hole, the axial direction of the bearing hole is defined as a front-and-back direction, the inner wall surface of the bearing hole is provided with at least two matching sections which are used for being correspondingly in close fit with an outer cylindrical surface of a bearing outer ring during use, and extend along the front-and-back direction, a radiating groove is formed between every two adjacent matching sections on the inner wall surface of the bearing hole, cooling fluid flows through the radiating grooves, and the bearing block is also provided with a fluid input channel and a fluid output channel which are communicated with the radiating grooves. The radiating device also comprises a supply system which is used for supplying the cooling fluid to the radiating grooves. A radiating method is convenient to use, rolling bearings are cooled by continuously and circularly inputting the low-temperature cooling fluid in a cooling pipeline and outputting the high-temperature cooling fluid from the cooling pipeline, and a work environment of the rolling bearings is improved.
Description
technical field [0001] The invention belongs to the technical field of heat dissipation for bearings, and in particular relates to a heat dissipation device for high-speed and heavy-duty rolling bearings. Background technique [0002] Rolling bearings will generate a lot of heat due to friction during operation. In conventional designs, this heat will be dissipated to the outside through the circulation of lubricating oil (grease) and heat conduction of the bearing seat, so as to ensure the normal operation of rolling bearings at the allowable temperature. When the rolling bearing bears a large load and runs at a high speed (close to the reference speed or limit speed of the bearing) or is in one of the working conditions, the heat generated by the bearing due to friction will increase sharply. The circulation and the heat conduction of the bearing seat cannot dissipate the heat generated by the bearing in time, so that the temperature of the bearing will continue to rise, w...
