The temperature conditions of the Tovar temperature gradient and the temperature difference of the tow under different specific pressures. The temperature difference here is the average of 8 points. Due to the thermal insulation of the fluoroplastic layer, the temperature difference of the tova is small. The average of the 8 measuring points did not exceed 1 °C under all operating conditions. The temperature difference of the tovar increases with the increase of the specific pressure, and the relationship with the linear velocity increases with the increase of the linear velocity at low speed, and reaches the maximum when the linear velocity reaches a certain value (15s). value. After that, the Towa temperature difference decreases with the increase of the line speed. The corresponding Tovar temperature gradient has the same law. The tovar temperature gradient was less than 0.16 ° C / cm under all operating conditions. The highest oil film temperature point is located near the oil side and the outer round side. The ratio of the oil film pressure ratio to the highest oil film pressure value and the unit specific pressure is called the pressure ratio. Its size reflects the influence of factors such as deformation of the tile on the oil film pressure. The ratio is between 2.1-2.76 under all test conditions and is in the optimal ratio range. It shows that the test bearing has a good tile shape and the bearing capacity of the bearing is large. The three circumferential curves are the inner diameter side, the middle diameter and the outer diameter side; both radial curves are on the oil side.

According to the deformation mechanism of the lower baffle supported by the spring beam, the circumferential tile shape is the same as the radial tile shape, but the values ​​are different. This means that there is also a problem of oil wedge divergence in the oil inlet area. The circumferential direction is the direction of oil flow, which will destroy the formation of dynamic pressure lubrication. For this reason, it is necessary to machine the profile in the inlet and outlet areas and remove the oil wedge divergence area. And decrease. It is because of the existence of such concave deformation that the plate-like distribution of the radial oil film pressure is formed, and the radial temperature difference is not large; it is also due to the circumferential pre-gava convex deformation (profile), week The pressure on the oil film will be parabolic. It should also be noted that the spring beam supporting the plastic tile steel base surface has a convex deformation relative to the surface of the mirror plate, and is also referred to only with respect to the mirror plate. If the thermal convex deformation of the steel base surface is deducted, the deformation of the steel base surface under the oil film pressure is also concave deformation.

It is not difficult to see that the total loss increases with the increase of the unit specific pressure and the linear velocity of the bearing bush, especially as the linear velocity increases. This is mainly because the stirring loss increases sharply as the linear velocity increases. The dynamic friction coefficient of the tile reduces the total loss of the bearing under various working conditions minus the agitation loss under the line speed condition, and the friction loss of the bearing bush can be obtained, and the dynamic friction coefficient of the tile surface can be calculated, and the spring beam is supported. Compared with tungsten-gold tiles, the dynamic friction coefficient of plastic tiles at medium and low speeds is lower than that of tungsten-gold tiles, while the dynamic friction coefficient of plastic tiles at high speeds can be higher than that of tungsten-gold tiles. This is due to the thermal insulation of the plastic and the elasticity of the elastic layer, so that the plastic tile at high speed has a large concave deformation, a low oil temperature and a thick oil film. It should be noted that the measurement of the loss is rough and part of the heat is transferred from the oil tank wall and other parts to the surrounding air and is not counted. Stirring loss at the same line speed is not difficult to see from the above test results. The spring beam support plastic tile thrust bearing is the same as the tungsten beam thrust bearing supported by the spring beam. It has a low temperature rise of the oil film, a uniform thickness of the oil film, and thus a large bearing area and pressure. The peak value is small and the bearing capacity is large; while the high temperature and heavy load have lower temperature rise, the oil film pressure ratio is smaller, and the advantage is more prominent. In addition, the elastic metal plastic tile has some advantages that the tungsten metal tile does not have (such as the high oil pressure jacking device can be eliminated), it can be said that the plastic tile can not only be used together with the spring beam support, but also has broad application prospects. .
