Description

A kind of axle envelope end bearing block

Technical field

The utility model belongs to the technical field of bearing block, and in particular to a kind of axle envelope end bearing block.

Background technology

All it is that bearing is installed at the both ends of axle on current many wind valve devices, then is arranged on by bearing block on flat board, so Afterwards by the rotation of the rotating band movable valve blade of drive shaft, so as to realize the opening and closing of valve, under the conditions of prior art Bearing block be cylinder type, centre offers bearing hole, there is problems in that：Need to add when bearing rotates and keep one Quantitative lubricating oil or lubricating grease, this just proposes requirement to the sealing property of bearing block, and bearing at work can not By the inner ring of bearing and outer ring top at grade, if top is at grade, bearing face abrasion can be accelerated, so Certain test just is proposed to the pattern of bearing block.

The content of the invention

The purpose of this utility model is to provide a kind of axle envelope end bearing block, asked with solve to propose in above-mentioned background technology Topic.

To achieve the above object, the utility model provides following technical scheme：A kind of axle envelope end bearing block, including pedestal, Described pedestal is stepped, two seat ears is provided with big disk side, the seat ear described in two is on pedestal center line institute It is symmetrical in plane, a bolt hole is respectively arranged with the seat ear described in two, from the bottom surface of the big disk of described pedestal Inwardly it is provided with a bearing hole, the internal diameter of described bearing hole is identical with the external diameter of the outer ring of institute installation bearing, depth and axle The width held is identical, the center line of described bearing hole and the centerline collineation of pedestal.

Preferably, offer one in the baseplane of described bearing hole to rise as high as the banks, the described internal diameter ratio risen as high as the banks is installed The external diameter of the outer ring of bearing is small, and the external diameter than the inner ring of installed bearing is big.

Preferably, be provided with a groove on the baseplane of described pedestal, the plane in the left side of described groove with The distance between right side plan risen as high as the banks is identical for the width of bearing to be installed.

Preferably, a circle seal groove, the depth ratio of described seal groove are provided with the right side plan of described pedestal Sealing strip to be mounted diameter it is small.

Preferably, an oil filler point is offered in the left surface of described pedestal, described oil filler point passes through pedestal, with putting down Groove penetrates, and described oil filler point is screw thread oil filler point.

Preferably, the corner on described pedestal is respectively provided with chamfering, the left plane of the big disk of described pedestal with it is small Turning between disk is arranged to right angle chamfering, and remaining chamfering is rounded corner.

Compared with prior art, the beneficial effects of the utility model are：Somewhat processing is only needed just to be molded after casting, It is easy to process；Oil filler point is added, can ensure there is the lubrication of abundance during bearing operation, while add seal groove so that profit Lubricating oil is not easy to flow out.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in embodiment of the present utility model is entered Row clearly and completely describes, it is clear that and described embodiment is only the utility model part of the embodiment, rather than all Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise Lower obtained every other embodiment, belong to the scope of the utility model protection.

As shown in Figure 1 and Figure 2, a kind of axle envelope end bearing block of the present utility model, its structure are as follows：One cylinder ladder The pedestal 1 of shape, two seat ears 2 being provided with big disk side, the two ears 2 are symmetrical on plane where the center line of pedestal 1, And a bolt hole 21 is respectively arranged with every seat ear 2, the bolt hole 21 is the through hole of cylinder, from the big of pedestal 1 The bottom surface of disk is inwardly provided with a bearing hole 3, and the internal diameter of the bearing hole 3 is identical with the external diameter of the outer ring of institute installation bearing, Depth is identical with the width of bearing, and the centerline collineation of the center line of bearing hole 3 and pedestal 1.

Generally, the inner ring of Self-aligning bearing, outer ring can not by approximately the same plane simultaneously dieback, if pushed up simultaneously Extremely, then Self-aligning bearing does not have aligning effect, so, one is offered in the baseplane of bearing hole 3 and rises as high as the banks 31, this rises as high as the banks 31 Internal diameter it is smaller than the external diameter of the outer ring of installed bearing, the external diameter than the inner ring of installed bearing is big, so bearing install After good, by dieback, inner ring can lack the movement of displacement for the only outer ring of bearing, serve the effect of aligning.Simultaneously in pedestal 1 Baseplane on be provided with a groove 32, the plane in the left side of the groove 32 is with 31 the distance between the right side plan of rising as high as the banks The width of bearing to be installed is identical.

Bearing, which needs to use lubricating oil in the running, to be lubricated, and in order to facilitate oiling, is offered in the left surface of pedestal 1 One oil filler point 5, the oil filler point 5 pass through pedestal 1, and with 31 insertions of rising as high as the banks, oil filler point 5 is screw thread oil filler point, and oil filler point 5 uses spiral shell Line oil filler point is to, in the inward turning intake plug of oil filler point 5, prevent outflow of lubrication oil after oil has been noted.

In order to prevent bearing block after mounting, lubricating oil may leak between pedestal 1 and mounting surface, so Be provided with a circle seal groove 4 on the right side plan of pedestal 1, the depth ratio of seal groove 4 sealing strip to be mounted diameter it is small； By compressing sealing ring during installation, outflow of lubrication oil is prevented.In order to avoid some sharp wedge angles on bearing block be present, in pedestal Corner on 1 is respectively provided with chamfering, and the turning between the left plane and roundel of the big disk of pedestal 1 is arranged to right angle chamfering, Remaining chamfering is rounded corner.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
