Embodiment 1

[0013] The device for reducing the bearing temperature of this embodiment has a structure such as figure 1 and figure 2 As shown, including the bearing body, there are two oil return holes 1 with a diameter of Ф6.5mm on the lower side of the body, and the oil return area is 47% of the oil inlet area. The lines are at a 45° angle. Wherein, the bearing is a fully immersed tilting pad bearing, and the oil return holes 1 are distributed on the pad fixing frame of the bearing, specifically, the oil return holes 1 are distributed in the gap between two pads 2 on the pad fixing frame.

[0014] When using, first refer to the actual object, measure the oil return hole, bearing inner diameter, shaft diameter and other related dimensional parameters one by one, use the measured dimensional parameters to calculate the oil inlet cross-sectional area and oil return cross-sectional area of ​​the bearing, and judge by comparison Whether the high bearing temperature is caused by insufficien...

Abstract

The invention relates to a device for reducing bearing temperature, comprising a bearing body, wherein a group of oil return holes is formed in the side lower part of the bearing body, and the axial lead of the oil return holes and the center line of a bearing form an angle of 45 degrees. According to the invention, by forming the oil return holes in the bearing, the oil return quantity is increased so as to reduce the temperature of the bearing, on the premise that the integral structure, the strength and the working environment of the bearing are not affected, the problem of overhigh radial bearing temperature can be effectively controlled, the phenomenon of overhigh bearing temperature caused by insufficient oil return is avoided, the phenomenon of interlocking jump caused by overhigh bearing temperature is further avoided, and stable production is ensured.

Description

technical field [0001] The invention relates to a device for reducing the temperature of a bearing. Background technique [0002] 4TYD112 air compressor is an air distribution set for steelmaking projects, with single-shaft four-stage compression, and its rated displacement is 53000m 3 / h, speed 7353r / min. In the prior art, there is an oil supply hole between every two tiles of the bearing, and 5 small oil supply holes are evenly arranged in the circumferential direction, and the oil return is through the gap between the fixed retaining ring and the shaft of the bearing pad under pressure. Forced discharge, during the process of oil return and discharge, the bearing temperature rises rapidly. After the unit has been running for a period of time, it is found that the radial bearing temperature has risen sharply, around 105°C, while the interlock trip value of the unit temperature measurement point is 120°C, which affects the stable operation of the air separation unit , re...
