Example Embodiment

[0009] Such as figure 1 As shown, a drum-shaped elastic oil tank supports a bidirectional thrust bearing, which is composed of the following components: Babbitt alloy tile 1, support pad 2, drum-shaped elastic oil tank 3, supporting iron 4, ring 5, connecting pipe 6, bearing seat 7 . The babbitt alloy bush 1 and the support bush 2 are connected by a key and form a thrust bearing bush. The thrust bearing bush is supported on the drum-shaped elastic oil tank 3. The spherical support 4 and the ring 5 are located in the drum-shaped elastic oil tank 3. The oil tanks 3 are communicated with each other through the connecting pipe 6, and the drum-shaped elastic oil tank 3 filled with hydraulic oil is fixedly installed on the bearing seat 7.

[0010] Such as figure 2 As shown, the axisymmetric structure of the drum-shaped elastic oil tank ensures that its upper surface is inclined under the action of the oil film pressure on the tile surface without being restricted by the direction. T...

Abstract

The invention relates to a bidirectional thrust bearing supported by drum-shaped elastic oil tanks. A babbit metal tile and a support tile are connected through a key to form a thrust bearing shoe together, the thrust bearing shoe is supported on the drum-shaped elastic oil tanks; spherical support iron and a circular ring are arranged in each drum-shaped elastic oil tank; the drum-shaped elastic oil tanks are communicated with each other through a communicating pipe; and the drum-shaped elastic oil tanks, which are filled with hydraulic oil, are fixedly mounted on a bearing support. The bidirectional thrust bearing has the advantages that the mounting and the maintenance are simple; the load-bearing capacity is high; loads among tiles can be balanced automatically; due to the spherical support iron, the security of the drum-shaped elastic oil tanks is improved; and through the adoption of the structure of a large-scale bidirectional thrust bearing, the bidirectional thrust bearing is suitable for the field of large-scale power generation motors of pump storage units and the other fields.

Description

technical field [0001] The invention relates to a two-way thrust bearing supported by a drum-shaped elastic oil tank. Background technique [0002] The two-way thrust bearing is one of the most important components in the generator motor of the pumped storage unit. It bears the weight of the rotor of the generator set and the axial water thrust. Its working performance is not only directly related to the safe operation of the unit, but also affects the output of the unit. and efficiency. As the capacity of the generator motor of the pumped storage unit increases, the load on the thrust bearing is also increasing, and the requirements for the two-way thrust bearing are also higher. The effective way to solve this problem is to adopt a new bidirectional thrust bearing pad and supporting structure and to optimize the bearing structure parameters. [0003] The currently used supporting structures such as spherical pillars are difficult to meet the development needs of the pump...
