Embodiment Construction
[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0021] as attached figure 1 and 2 As shown, the present invention provides an automatic centering device for intermediate bearings, which includes an inner bush 1, an outer bush 3, an inner rubber layer 2, an intermediate bush 4 and an outer rubber layer 5;
[0022] The inner bushing 1, the outer bushing 3 and the middle bushing 4 are all metal materials, the inner bushing 1 and the outer bushing 3 are complete rings, the middle bushing is an arc-shaped sheet structure with two petals of the same size, and the outer bushing The rubber layer 5 is vulcanized between the outer bush 3 and the middle bush 4, and the inner rubber layer 2 is vulcanized between the inner bush 1 and the middle bush 4; the inner bush 1 and the outer bush 3 are not the same as the middle bush 4 The corresponding top and bottom of the continuous part form a partial hollow structure....

The invention discloses automatic alignment devices for an intermediate bearing. Each automatic alignment device comprises an outer bushing, an outer rubber layer, an intermediate bushing, an inner rubber layer and an inner bushing, wherein the outer bushing, the intermediate bushing and the inner bushing are all metal parts; the outer bushing is sleeved on the intermediate bushing and the intermediate bushing is sleeved on the inner bushing; the outer rubber layer is vulcanized between the outer bushing and the intermediate bushing; and the inner rubber layer is vulcanized between the intermediate bushing and the inner bushing. Each automatic alignment device as a whole is mounted and fixed in a corresponding base through the corresponding outer bushing. Machine feet of the intermediate bearing is fixedly mounted in the inner bushings. The automatic alignment devices for the intermediate bearing utilize the elastic deformation of the inner rubber layers and the outer rubber layers toenable the intermediate bearing to automatically adjust the posture along with a main shaft so as to improve the alignment state of a shaft system and effectively isolate the vibration transmission ofthe shaft system to a hull through the bases.
Description
technical field [0001] The present invention is applied to the intermediate bearing in the cabin of a ship. Through its application, the alignment state of the shafting system during operation can be improved, and the deterioration of the alignment state of the shafting system caused by various factors such as hull deformation, impact, and operating state changes during operation can be eliminated. At the same time, it can effectively isolate the vibration transmission from the shaft system to the hull through the bearing base. Background technique [0002] At present, the intermediate bearing in the shafting cabin of the ship is fixed on the structural foundation by twisted bolts. This installation method has the following problems: [0003] a) Changes in hull deformation, loading capacity, and operating conditions lead to changes in the actual alignment of the ship's shafting, and deterioration of the alignment of the bearings, resulting in local loads on the bearings exce...
