Abstract
Description
Technical field:
[0001] The utility model relates to the technical field related to a bearing seat, and more specifically to a novel thrust sliding bearing for ships. Background technology:
[0002] Sliding bearings are widely used in all walks of life. Bearing shells are generally made of bearing alloys. During the operation of the ship, the rotating shaft will move as the ship tilts and sways, generating axial thrust on the bearing. If the end face of the bearing shell is used directly to bear the force, it is easy to cause alloy wear. In severe cases, the shell will burn out. In this case, the only option is to replace the bearing shell, which is not only costly but also unsafe.
[0003] Therefore, if the thrust structure of the bearing is changed so that it has a certain thrust bearing capacity, this problem can be well solved. Utility model content:
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a novel thrust sliding bearing for ships, which can form an effective oil film on the front end face and the rear end face of the bearing body, can withstand a smaller axial load, reduce end face wear, and improve thrust bearing capacity.
[0005] The solution of the utility model to solve the technical problem is:
[0006] A novel thrust sliding bearing for ships comprises a bearing body, a front end face and a rear end face of the bearing body are formed with a plurality of wedge-shaped blocks protruding outwards, and an outer wall face of the wedge-shaped block is formed with an oil guide groove;
[0007] The outer wall of the bearing body is formed with oil inlet ring grooves near the front and rear ends, and the inner wall surface of the upper part of the oil inlet ring groove is formed with a plurality of vertical oil inlet holes extending toward the central axis of the bearing body, and a transverse oil inlet hole is formed between the two corresponding front and rear wedge blocks of the upper part, and the front and rear ends of the transverse oil inlet hole extend out of the inner end surfaces of the oil guide grooves of the two corresponding front and rear wedge blocks and communicate with the two oil guide grooves, and the corresponding vertical oil inlet hole is communicated with the transverse oil inlet hole.
[0008] The outer end of the vertical oil inlet hole is communicated with the oil inlet ring groove, and the inner end of the vertical oil inlet hole extends out of the inner side wall of the corresponding transverse oil inlet hole and is communicated with the transverse oil inlet hole.
[0009] The outstanding effects of the utility model are:
[0010] It can form an effective oil film on the front and rear faces of the bearing body, can withstand smaller axial loads, reduce end face wear, and improve thrust bearing capacity. Description of the drawings:

[0013] Figure 3 yes Figure 1 Schematic diagram of the local structure after AA rotation. Specific implementation method:
[0014] For example, see Figures 1 to 3 As shown, a new thrust sliding bearing for ships includes a bearing body 10. The bearing body 10 is an annular body composed of two upper and lower semicircular arc-shaped bearing shells pressed against each other.
[0015] Furthermore, a plurality of outwardly protruding wedge blocks 11 are formed on the front and rear surfaces of the bearing body 10, an oil guide groove 12 is formed on the front wall surface of the wedge block 11 on the front surface of the bearing body 10, and an oil guide groove 12 is formed on the rear wall surface of the wedge block 11 on the rear surface of the bearing body 10;
[0016] Furthermore, the front and rear ends of the outer wall of the bearing body 10 are formed with conical wall surfaces, and the two conical wall surfaces of the outer wall of the bearing body 10 are formed with oil inlet ring grooves 13. A plurality of vertical oil inlet holes 14 extending toward the central axis of the bearing body 10 are formed on the inner wall surface from the upper part of the oil inlet ring groove 13 to the left and right side edges, and a plurality of transverse oil inlet holes 15 extending forward and backward are formed from the upper part of the bearing body 10 to the middle part of the left and right sides. The two ends of the transverse oil inlet holes 15 extend out of the inner wall surfaces of the oil guide grooves 12 of the two corresponding wedge blocks 11 in the front and rear and communicate with the two oil guide grooves 12, and the corresponding vertical oil inlet holes 14 are communicated with the transverse oil inlet holes 15.
[0017] The outer end of the vertical oil inlet hole 14 is communicated with the oil inlet ring groove 13 , and the inner end of the vertical oil inlet hole 14 extends out of the inner side wall of the corresponding transverse oil inlet hole 15 and communicates with the transverse oil inlet hole 15 .
[0018] The oil guide grooves 12 of the wedge block 11 at the lower part of the front and rear surfaces of the bearing body 10 are vertical grooves, and both ends thereof extend out of the top and bottom surfaces of the wedge block 11 .
[0019] The oil guide grooves 12 of the wedge blocks 11 at the top and both sides are elongated grooves, and one end of the oil guide grooves close to the outer wall of the bearing body 10 extends out of the corresponding wall surface of the wedge block 11 .
[0020] A plurality of connecting screw holes are formed in the middle of the outer side wall of the bearing body 10 .
[0021] When the present embodiment is in use, the external lubricating oil enters the oil inlet ring groove 13 of the bearing body 10 through the oil inlet hole of the bearing seat (it drips from the upper oil inlet hole of the bearing seat into the upper part of the oil inlet ring groove 13), and then the oil flows along the oil inlet ring groove 13, part of the oil enters the corresponding transverse oil inlet hole 15 through the vertical oil inlet hole 14, and then enters the corresponding oil guide groove 12 of the wedge block 11 from the front and rear ends of the transverse oil inlet hole 15, and the oil flows out along the oil guide groove 12; and as the end face of the rotating component rotates along the outer end face of the wedge block 11, the oil is smeared on the end face, and at the same time, the excess oil will be brought into the oil guide groove 12 below and the outer end face of the wedge block 11 below will also be smeared with oil, and finally an effective oil film is formed on the outer end faces of all the wedge blocks 11, which can withstand a smaller axial load, reduce the wear of the end face, and improve the thrust bearing capacity.
