Abstract

The utility model relates to a laminated bearing, which relates to a support for a shaft in mechanical transmission. Figure (1) is an assembly profile chart of the laminated bearing, the shaft and a bearing seat. The laminated bearing is composed of a plurality of hard laminated pieces (8) and soft laminated pieces (9) which are laminated in a mode of interphase arrangement; the utility model is sheathed on a rotary shaft (1) and assembled in a bearing housing (5); the rotation of an adjusting screw (10) can adjust the axial clamping force of the utility model to lead to the radial deformation of the soft laminated pieces and make up for the abrasion quantity of the bearing. The interphase arrangement of the hard laminated pieces and the soft laminated pieces makes lube favorably sealed. Gaps are formed between the hard laminated pieces and the rotary shaft, and the soft laminated pieces match tightly with the shaft, which has buffering effect on the impact force of the shaft.

Description

Laminated bearing

The utility model relates to direct supporting---the laminate patch bearing of the axle in a kind of mechanical transmission, and the laminate patch bearing is assemblied in the bearing support, and bearing support is the false bearing of axle.

At present, directly supporting of the axle in the mechanical transmission, a part is realized by whole sliding bearing.This is a kind of simple bearing for a long time of having continued to use.

Whole sliding bearing maintenance trouble after the wearing and tearing, is often wanted the integral replacing bearing, high material consumption; Whole sliding bearing encapsulation is poor, and lubricant oil expends greatly, and leaks seriously contaminated site; Between whole sliding bearing and the rotating shaft only is the skim oil film, and the impact force of countershaft does not have buffer function, and rotating shaft damages easily.

The purpose of this utility model is the bearing that a kind of novelty will be provided---the laminate patch bearing, progressively replace existing whole sliding bearing, and reduce materials consumption, reduce the place and pollute, prolong the rotating shaft life-span.

The structure of laminate patch bearing as shown in Figure 1, being coincided alternately by soft laminate patch (2) and hard laminate patch (3) forms, and is enclosed within the direct supporting that rotating shaft (1) has just become rotating shaft---laminate patch bearing.The hard laminate patch of laminate patch bearing is a hard sheet bearing parts, and big gap is arranged between the rotating shaft, makes easily; Soft laminate patch is soft sheet bearing parts, cooperate with axle tightr, can radial deformation, therefore fit tolerance is not had harsh requirement, easy to manufacture.

Unique texture of the present utility model has formed the adjustable and the self-enclosed property of laminate patch bearing, thereby has overcome the number of drawbacks of whole sliding bearing.

Per two hard laminate patches of soft laminate patch clamping a slice can be considered one " junior unit " of laminate patch bearing.Because hard laminate patch and rotating shaft are gapped, can store lubricant oil.Soft laminate patch is made by plastic material, can relax the impact force of rotating shaft, prolongs the rotating shaft life-span.A laminate patch bearing is combined by several " junior units ", makes the laminate patch bearing have self-enclosed property.Lubricant oil is difficult for leaking, and reduces oil consumption and field-free ground contamination.Because soft laminate patch is to be made by soft plasticity sheet shaped materials, regulate the axial clamping force of laminate patch bearing, just can cause the radial deformation of soft laminate patch, remedy the wear extent of bearing, the laminate patch bearing has adjustable.Be convenient to maintenance, save material.

The laminate patch bearing be the axle direct supporting, it must be contained in the axle false bearing---could use in the bearing support, Fig. 2 be the laminate patch bearing housing in rotating shaft, be contained in the sectional drawing in the bearing support.

Below in conjunction with Fig. 2, further set forth the laminate patch bearing performance.The laminate patch bearing that some hard laminate patches (8) and soft laminate patch (9) coincide alternately and form is enclosed within the rotating shaft (1), is contained in the bearing shell (5).To stud with the fixed cover (4) of seal ring (2) by fastening screw trip bolt (3), be firmly fastened to left side in bearing shell (5).The right-hand member of bearing shell (5) has an adjustable cap (13), and seal ring (12) is wherein arranged, and adjusting screw (10) and stopping shim (11) are arranged on it.Open stopping shim (11), rotation adjusting screw (10) just can be adjusted the axial force of adjustable cap (13) to soft laminate patch (9), causes the radial deformation of soft laminate patch, makes the laminate patch bearing have adjustable.Lubricant oil (6) in the extraordinary lubricating cup (7) provides lubricant oil by the gap of oil circuit between hard laminate patch and rotating shaft of laminate patch bearing inside.Some soft laminate patches have just realized the self-enclosed property of laminate patch bearing.The bearing shell, parts such as fastening cover and adjustable cap have been formed bearing support, are linked by the set screw (14) of bearing support and applying portion.

Claims

1, the chip select bearing is the direct supporting of the axle in the mechanical transmission, as present general whole sliding bearing, must be assemblied in the bearing support and use, its technical characteristics is that the laminate patch bearing is to be coincided alternately with soft laminate patch by hard laminate patch to be in the same place, the bearing support of packing into, be enclosed within on the transmission shaft, as the direct supporting of axle.

2, laminate patch bearing according to claim 1 is characterized in that hard laminate patch and soft laminate patch all are the bearing partss of sheet.
