Problems solved by technology

[0004] In order to solve the above-mentioned technical problem of unbalanced force between the supporting pads of the existing supporting sliding bearing, the object of the present invention is to provide a load-balancing sliding bearing, which uses a rotating load-balancing block and a moving load-balancing block. The load equalizing adjustment mechanism adjusts the gap between the supporting pads and the journal, and finally achieves a uniform gap between the supporting pads and the journal through force balance to achieve load balancing, and achieves a good uniform load distribution between the supporting pads to achieve Characteristics of force balance among supporting tiles

Embodiment 1

[0037] This embodiment is basically as follows: Figure 1 The embodiment provides a uniform load sliding bearing for balancing the radial force of the rotor; The sliding bearing is divided into four layers from inside to outside, including the outermost bearing shell body, the innermost supporting pad 5 and the load sharing adjustment mechanism arranged between the outer bearing shell body and the supporting pad 5. The bearing shell body provided in this embodiment includes the upper half 1 and the lower half 2 of the bearing shell body. The upper half 1 and the lower half 2 of the bearing shell body are in surface contact and realize fixed and removable connection, and the whole bearing shell body is in a ring structure after assembly, An installation space for installing the journal 6 and each support pad 5 is formed in the annular structure, so that each support pad 5 is evenly arranged around the journal 6. The design purpose of the load sharing adjustment mechanism is to solve...

Embodiment 2

[0048] Embodiment 2 is basically the same as embodiment 1, with the difference that: Figure 3 and Figure 4 As shown in the figure: as a preferred embodiment of embodiment 1, a spray block 10 for injecting oil into the bearing is installed on the rotating load sharing block 4 in this embodiment, the oil inlet of the spray block 10 is connected with the oil inlet hole 8 of the rotating load sharing block 4, and the oil outlet hole of the spray block 10 corresponds to the support pad 5.

[0049] To sum up, the uniform load sliding bearing in this embodiment has simple structure and fast assembly speed. Combined with the oil inlet ring groove 9 on the bearing shell body, the oil inlet hole 8 on the rotating uniform load block 4 and the spray block 10, when the bearing is in service, the lubricating oil can enter the spray block 10 through the oil inlet ring groove 9 on the bearing shell body, the bearing shell body and the oil inlet hole 8 of the rotating uniform load block 4, and dir...

Abstract

The invention discloses a load balancing sliding bearing, which relates to the technical field of sliding bearings; it comprises a bearing body, a supporting pad block and a load balancing adjustment mechanism. The blocks are arranged corresponding to the supporting pads and are in contact with the supporting pads. The moving load equalizing block is connected with the bearing body and the rotating load equalizing block, so that the sliding of the moving load equalizing block along the radial direction of the bearing can be transformed into the sliding of the rotating load equalizing block along the Circumferential rotation, and then during the operation of supporting the sliding bearing, the supporting pads are linked together through the load-sharing adjustment mechanism, and the gap between each supporting pad and the journal is adaptively adjusted; through the implementation of this technical solution, the current situation is effectively solved. There is a technical problem of unbalanced force between the supporting pads of the sliding bearing. The uniform clearance and uniform force of the pads are respectively for the upper half tile and the lower half tile. The load is evenly distributed to achieve the characteristics of force balance among the supporting tiles.

Description

technical field [0001] The invention relates to the technical field of sliding bearings, in particular to a load sharing sliding bearing. Background technology [0002] Sliding bearings are divided into supporting sliding bearings and thrust sliding bearings. Supporting sliding bearings are used to balance the radial force of the rotor, and thrust sliding bearings are used to balance the axial thrust of the rotor. In the prior art, the sliding bearing with uniform load block has been applied in the thrust bearing, such as the self balancing thrust bearing of Kingsbury company and Waukesha company, but the application of uniform load block in supporting sliding bearing has not been reported. [0003] As the existing support sliding bearing is used in the application of large specific pressure and high speed, the inventor of the application has found in practice that the existing support sliding bearing has the following defects: due to the influence of different thickness and impr...
