Description
Technical field
The present invention relates to bearing arrangement part field, specially a kind of half shaft bearing block.
Background technology
Bearing holder device is widely used in various plant equipment, and the bearing block of existing bearing holder device is monoblock type,
Be mostly installed at two ends of torsion bar, top and the bogie of bearing block are connected, in installation process, it is necessary to first by torsion bar shaft through
On bearing block, then bearing block and torsion bar shaft be co-mounted on the bogie of car, so need larger installing space, for
Narrow space and bearing block must be separately mounted to the situation on bogie with torsion bar shaft, to improve the weldability of bearing block
Can, the material selection of bearing block is that hardness is not high but the preferable steel of welding performance, between bearing block inwall and bearing outer ring are
Gap coordinates, and there is friction, to improve the wearability of bearing block inwall, generally electroplates one layer of electrodeposited coating to improve it in inner wall surface
Anti-wear performance.But bearing block is rigidly poor, it is easily deformed after being on active service for a long time, needs first to repair enough when returning repair in shop reason
Size, is then ground to design size, and reparation must electroplate thicker electrodeposited coating again to enough sizes and just can guarantee that.But
The finite thickness of electrodeposited coating, most thick no more than 0.15mm, otherwise its adhesion is greatly reduced;In electroplating process, such as protect
Shield is not in place, can cause bearing block end thread corrosion.So the requirement of people can not be completed.
The content of the invention
It is an object of the invention to provide a kind of half shaft bearing block, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of half shaft bearing block, including bearing block main body,
The bearing block body interior is provided with stiff dough figure layer, and lower stiff dough figure layer, the axle is provided below in the upper stiff dough figure layer
Housing body top is provided with below the first internal surface layer, first internal surface layer and is provided with the second internal surface layer, the bearing block master
Body bottom, which is provided with the 3rd internal surface layer, the bearing block main body, is provided with spacing hole, and ring is provided with the left of the spacing hole
It is provided with shape flange plate, the upper annular flange plate on arc angle, the arc angle and is provided with arc angle circular hole, the upper ring
It is provided with shape flange plate in chamfering, the bearing block main body and is provided with waist-shaped hole, is provided with the left of the bearing block main body
It is provided with the right side of breach, second internal surface layer below lower waist-shaped hole, the 3rd internal surface layer and is provided with lower annular flange plate, institute
State to be provided with outside annular on the right side of lower annular flange plate and extend plank, the annular flange plate is integrated into the bearing block main body
The overall structure of type.
It is preferred that, the thickness of the upper hard-surface coating and the lower hard-surface coating is 0.2mm~0.4mm.
It is preferred that, the internal diameter size of first internal surface layer is more than the internal diameter size of the 3rd internal surface layer.
It is preferred that, at least one opening end of the bearing block main body is provided with the breach or the outer extension of the annular
Plate.
It is preferred that, the arc angle circular hole and the upper mounting hole, the lower mounting hole be radially arranged or cloth vertically
Put.
Compared with prior art, the beneficial effects of the invention are as follows：Bearing block agent structure is simple, has a wide range of application, bearing
The hard-surface coating that the operating power brought acts on bearing block is operated, hard-surface coating can offset the effect of bearing, reduce bearing
The deformation probability of seat;And because the thickness of hard-surface coating is not limited, by the high-wear resistance and thickness of hard-surface coating
Size, reduces the abrasion between bearing and bearing block, increases the service life of bearing block, reduces the frequency of maintenance of bearing block.Will
Existing electrodeposited coating is changed to the hard-surface coating that spraying is formed, and very well, the thickness of spraying will not also cause painting to the adhesion property of coating
Layer comes off, and the limitation of size is not sprayed, it is possible to increase the wear-resisting intensity between bearing and bearing block, for bearing base inner surface
The protection of comprehensive adhesiveness is carried out, the corrosion probability of bearing block is reduced.Due to using spraying method in bearing base inner surface shape
Into coating, coating thickness is easily controlled, and thickness range is very wide, due to no thickness limitation hardness can higher, wearability more
Good, spraying method adhesion is more preferable so that the service life of bearing block is longer, in coating preparation process will not damaging substrate and
Miscellaneous part.
