[ detailed description ] A
The utility model provides a from slidingtype bearing of area heat dissipation function, includes inner circle 1 and outer lane 2, and inner circle 1 is equipped with the connecting hole 11 that is used for supplying fixed axle to connect along the axial, and outer lane 2 is equipped with along the axial and is used for rotating the rotation hole 21 of being connected with inner circle 1, and inner circle 1 is equipped with along circumference with rotation hole 21 sliding connection's sliding connection structure 12, is equipped with heat dissipation channel 22 in the outer lane 2, and outer lane 2 has laid the vent 23 that is linked together with heat dissipation channel 22 along circumference.
Preferably, the heat dissipation passage 22 is annular and penetrates the outer ring 2, thereby further improving the heat dissipation effect.
In order to further improve the heat dissipation effect, the ventilation opening 23 is of a spiral structure with a narrow inner part and a wide outer part, so that a spiral air duct is formed, and the air inlet efficiency and the air outlet efficiency of the ventilation opening 23 are improved.
In order to prevent the rotation hole 21 from being separated from the inner ring 1 while the outer ring 2 is rotatably connected, the sliding connection structure 12 is an annular groove which is slidably matched with the rotation hole 21.
In order to effectively limit the inner ring 1 and the outer ring 2 to prevent the inner ring and the outer ring from axially moving, limiting plates 13 are arranged at two ends of the inner ring 1, and an annular groove is formed between the two limiting plates 13.
In order to ensure the compactness of the whole structure, the two ends of the outer ring 2 are provided with accommodating cavities 24 for accommodating the limiting plates 13.
Preferably, three ventilation openings 23 are uniformly distributed in the circumferential direction of the outer ring 2. Of course, the number of the ventilation openings 23 may be other than the number of the ventilation openings 23, but in order to ensure the heat dissipation effect and prevent the wind resistance from being large to affect the normal operation of the sliding bearing, the optimal number of the ventilation openings 23 is still three and is uniformly distributed in the circumferential direction of the outer ring 2.
The inner ring 1 is fixedly connected with the fixed shaft through a connecting hole 11, and the outer ring 2 is connected with an external transmission part through the periphery (such as a transmission belt which is wound on the periphery of the outer ring 2). When the sliding bearing works, the external transmission part drives the outer ring 2 to slidably rotate relative to the inner ring 1, the outer ring 2 can drive external air to circulate between the ventilation opening 23 and the annular heat dissipation channel 22, so that continuously flowing heat dissipation air is automatically formed and the heat dissipation is carried out on the inner part of the sliding bearing, the function of self heat dissipation is realized, the abrasion speed of the sliding bearing is reduced, and the service life of the whole sliding bearing is prolonged.
