A thrust bearing with tapered raceways on rings

Abstract

This utility model belongs to the field of thrust bearings, specifically relating to a thrust bearing with a tapered raceway. It includes a shaft ring, with a seat ring fixedly mounted to the lower end of the shaft ring by bolts. Multiple annular and evenly distributed rollers are movably fitted between the shaft ring and the seat ring. The upper ends of the rollers contact a piston, and a pressure block is fixedly connected to the top of the piston. The pressure block is slidably connected to the shaft ring. This utility model, through the design of the rollers, causes them to roll within the raceway, thereby reducing rolling friction and rolling resistance. During the rotation of the rollers, they compress the piston, pushing it and causing the pressure block to move upwards. The pressure block then compresses a sponge pad, squeezing out the lubricating oil inside the pad. The lubricating oil then automatically lubricates the rollers, further reducing rolling friction and extending service life. Furthermore, lubricant replenishment is convenient and easy to use.

Description

Technical Field

[0001] This utility model relates to the field of thrust bearing technology, specifically a thrust bearing with tapered raceways on the raceways. Background Technology

[0002] A thrust bearing is a type of bearing specifically designed to withstand axial loads (forces along the axial direction). This type of bearing is typically designed to withstand high axial loads without damage, making it very useful when it is necessary to support rotating components on the bearing while also bearing axial loads.

[0003] Utility model patent CN215890771U discloses a planar thrust bearing, belonging to the field of bearing technology. It includes a shaft ring, a seat ring, a damping ring, and an outer cover. The shaft ring, damping ring, and seat ring are assembled in parallel to form an assembly structure. The outer cover is fixed to the shaft ring or the seat ring and covers the outer circumferential surface of the assembly structure. The damping ring has multiple oil storage holes on its side in contact with the shaft ring. These oil storage holes are evenly distributed on the circumference of five virtual circles of different diameters, coaxially arranged. The oil storage holes on two circumferences spaced one circumference apart are arranged along the same radial direction. This utility model reduces the frictional resistance between the shaft ring and the damping ring and improves the bearing's service life by providing multiple densely distributed oil storage holes on the damping ring.

[0004] In existing technologies, lubrication of the bearing rollers is inconvenient during the use of thrust bearings, and the high frictional force during roller rotation can affect their service life. Therefore, improvements are needed. Utility Model Content

[0019] Please see Figure 1 , Figure 2 The top of the pressure block 5 is in contact with a sponge pad 7, which is fixedly connected to the shaft ring 1. The shaft ring 1 has a flow channel 8 inside, which communicates with the sponge pad 7. A plug 12 is threadedly connected inside the flow channel 8. A guide rod 10 is fixedly connected to the upper end of the pressure block 5, and the guide rod 10 is slidably connected to the shaft ring 1. A first spring 11 is provided on the outside of the guide rod 10. One end of the first spring 11 is fixedly connected to the pressure block 5, and the other end of the first spring 11 is fixedly connected to the shaft ring 1. By designing the first spring 11, the force of the first spring 11 can act on the pressure block 5. A support mechanism 9 is provided on the shaft ring 1.

[0020] Please see Figure 1 , Figure 3 The support mechanism 9 includes a connecting block 91. The upper end of the seat ring 2 is fixedly connected to the connecting block 91. A support column 92 is slidably sleeved on the outer side of the connecting block 91. A limit screw 93 is threadedly connected inside the support column 92. The limit screw 93 is slidably connected to the connecting block 91. By designing the limit screw 93, the support column 92 and the connecting block 91 can be connected and fixed. The support column 92 is slidably connected to the shaft ring 1. A fixing rod 94 is fixedly connected inside the support column 92. A second spring 95 is provided on the outer side of the fixing rod 94. One end of the second spring 95 is fixedly connected to the slider 96, and the other end of the second spring 95 is fixedly connected to... The support column 92 is fixedly connected. By designing a second spring 95, the force of the second spring 95 can act on the slider 96. The slider 96 is slidably sleeved on the outside of the fixed rod 94. The slider 96 is slidably connected to the support column 92. The slider 96 is movably sleeved with a retaining ball 97.

[0021] The specific implementation process of this utility model is as follows: During use, when the bearing is working, the roller 3 will rotate between the shaft ring 1 and the seat ring 2. When the roller 3 rotates, it will contact the piston 4 and squeeze the piston 4. The piston 4 will be squeezed and pushed upward. The piston 4 will separate from the inner wall of the shaft ring 1. The piston 4 will drive the pressure block 5 to move upward. The pressure block 5 will squeeze the sponge pad 7. At the same time, the pressure block 5 will drive the guide rod 10 to move upward. The pressure block 5 will squeeze the first spring 11. At this time, the lubricating oil stored inside the sponge pad 7 will be squeezed out. The lubricating oil flows through the through hole 6. Then the lubricating oil flows out through the gap between the piston 4 and the shaft ring 1. The lubricating oil can automatically lubricate the roller 3, which can further reduce rolling friction and improve service life. It can be removed by rotating the plug 12. The flow channel 8 makes it convenient to replenish the lubricating oil and convenient to use.

[0022] The support column 92, positioned between the shaft ring 1 and the seat ring 2, provides auxiliary internal support, enhancing the bearing's structural strength, increasing the axial force it can withstand, and improving its durability. To remove the support column 92, first unscrew the limiting screw 93 from the support column 92 to separate it from the connecting block 91. Then, separate the shaft ring 1 from the seat ring 2 and pull the support column 92 outwards. This causes the retaining ball 97 to move, rolling along the arc surface of the groove 98. The retaining ball 97 is pushed horizontally by the compression, causing the slider 96 to slide along the fixed rod 94 and compress the second spring 95, separating the retaining ball 97 from the groove 98. The support column 92 can then be pulled out from the shaft ring 1 for easy inspection and maintenance of the bearing's internal structure.
