Description

Technical Field

[0001] This utility model belongs to the technical field of thrust bearing pads, and particularly relates to a thrust bearing pad mounting structure. Background Technology

[0002] Thrust bearing pads are used in end-face support applications of rotating mechanisms in steelmaking, petrochemical, and chemical industries.

[0003] Currently, the thrust bearing pads can rotate 360° with the thrust disc, and some collisions between them are inevitable, causing excessive vibration, alloy damage, and other problems that affect unit operation. Therefore, we propose a thrust bearing pad installation structure. Utility Model Content

[0004] The purpose of this utility model is to provide a thrust bearing pad mounting structure to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a thrust bearing pad mounting structure, comprising: A gasket, wherein a thrust plate is provided on the gasket, and the top of the thrust plate is provided with several tile slots, which are interconnected. The thrust plate is provided with several round holes. Several tiles are snapped into tile slots, and the bottom of each tile is provided with a fulcrum and a limit screw hole; A plurality of through holes are provided, all of which are formed on the gasket. A connecting screw is inserted into each of the through holes, and the upper end of the connecting screw extends into the thrust plate. A limit screw is inserted into the round hole, and the upper end of the limit screw extends into the limit screw hole.

[0006] In this technical solution, by adjusting the bearing installation structure, the swing of the bearing is controlled within a certain range, avoiding mutual rotation and collision between bearings that could cause unit efficiency reduction or even shutdown. At the same time, by reasonably controlling the swing amplitude through connecting screws, the stability of the oil film's support force on rigid components is greatly enhanced, reducing unit vibration and increasing the unit's service life. The bearing bearing's bearing bearing bearing area is increased, enhancing the support force. Bearing bearing bearing slots are set in the thrust plate to allow the bearing bearing to sink and limit its rotation amplitude. Adjust the position of the fulcrum and limit screws under the bearing block so that the fulcrum is not in the center and is far away from the oil inlet side. As the center of gravity of the bearing block will tilt towards the oil inlet side, a stable oil film will be formed on the surface of the bearing block under the action of the thrust plate. At the same time, the limit screws can ensure that the bearing block does not fall off and limit the amplitude of fluctuation and swing, thus ensuring the safety of the bearing block and the stability of the unit.

[0007] In the above technical solution, furthermore, the upper end of the connecting screw is threadedly connected to the thrust plate.

[0008] In this technical solution, the upper end of the connecting screw is secured to the thrust plate, ensuring the structural stability of the thrust plate. In the above technical solution, further, the upper end of the limiting screw is threadedly connected to the limiting screw hole.

[0009] In this technical solution, it is ensured that the upper end of the limiting screw can be fixed in the screw hole. In the above technical solution, furthermore, the bottom end of the tile is adapted to the tile slot.

[0010] In this technical solution, it is ensured that the bottom end of the tile can be inserted into the tile slot.

[0011] In the above technical solution, furthermore, the number of the plurality of through holes is at least 8, and the number of the plurality of connecting screws is at least 8.

[0012] In this technical solution, it is ensured that the upper end of the connecting screw can pass through the through hole and be fixed on the thrust plate.

[0013] In the above technical solution, furthermore, the number of the aforementioned tiles is at least eight.

[0014] In this technical solution, by adjusting the bearing installation structure, the swing of the bearing is controlled within a certain range, avoiding mutual rotation and collision between bearings that could cause unit efficiency reduction or even shutdown, increasing the bearing bearing bearing bearing area and enhancing support.

[0015] In the above technical solution, furthermore, the number of the plurality of limiting screws is at least 8, and the number of the plurality of limiting screw holes is at least 8.

[0016] In this technical solution, it is ensured that the upper end of the limiting screw can enter the limiting screw hole and fix the tile.

[0017] The beneficial effects of this utility model are: 1. The thrust bearing pad mounting structure, by adjusting the tilting pad mounting structure, controls the swing of the bearing pad within a certain range, avoiding mutual rotation and collision between the bearing pads that could cause unit efficiency reduction or even shutdown. At the same time, by reasonably controlling the swing amplitude through the connecting screws, the stability of the oil film supporting the rigid components is greatly enhanced, reducing unit vibration and increasing the service life of the unit.

[0018] 2. The thrust bearing pad mounting structure increases the bearing pad's bearing area and enhances its support force. Pad slots are provided on the thrust plate to allow the pads to sink and limit their rotation range. The positions of the fulcrum and limit screws are adjusted below the pads so that the fulcrum is not in the center and is far from the oil inlet side. As the center of gravity of the pads tilts towards the oil inlet side, a stable oil film is formed on the pad surface under the action of the thrust plate. At the same time, the limit screws can ensure that the pads do not fall off and limit the amplitude of fluctuations and swings, ensuring the safety of the pads and the stability of the unit.
