Abstract
The invention belongs to a machine work class and in particular relates to a method for assembling a hydro-hybrid bearing, which is characterized in that: a bearing shell is fixed on a base; two ends of an axis is propped by the finial of the axis; the finial is also fixed on the base; two bearing inner rings are machined and respectively sleeved between the axis and the shell; an oil circuit on each inner ring is switched on in order that a hydrostatic system between the inner ring and the axis can operate; the inner rings float on the axis; adhesive is input in the gap between the shell and the inner rings; after the adhesive is solidified, the axis and the shell are dismounted from the base, that is completing the assembly of the hydro-hybrid bearing. As the homogenization of hydrostatic oil film in the method for assembling the hydro-hybrid bearing, the isotropic gaps between two inner rings and the axis are uniform, thereby ensuring the coaxiality between two inner rings; as the two inner rings are respectively machined, the degree of symmetry of each oil sink can be ensured. The hydro-hybrid bearing assembled by the assembling method of the invention has high precision, a reasonable structure and small axis vibration.
Description
Technical field
The invention belongs to field of mechanical manufacture technology, specifically is a kind of assembly method of dynamic and hydrostatic bearing.
Background technique
Dynamic and hydrostatic bearing is the bearing that a kind of performance is good, the life-span is long, be applicable on the principle that high speed and ultra high speed support, but the depth width of the oil groove of the necessary symmetry of each oil pocket that requires the support two ends on the structure, each oil pocket must be consistent, and the center line of two support ends is necessary coaxial.In reality is made, have inevitable error owing to make assembling, the coaxality of the degree of symmetry of each oil groove and two support ends is difficult to accomplish sufficiently high precision, when bearing high speed or ultra high speed rotation, running shaft can produce vibration, makes the dynamic and hydrostatic bearing precision reduce.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of assembly method of scientific and reasonable, simple and convenient, dynamic and hydrostatic bearing that precision is high is provided.
Technological scheme of the present invention is as follows:
A kind of assembly method of dynamic and hydrostatic bearing is characterized in that: bearing housing is fixed on the pedestal, and with top the withstanding of axle, axle toply also is fixed on the pedestal with the axle two ends; Process ring in the two bearings, ring in the two bearings is enclosed within respectively between axle and the bearing housing, connect the oil circuit on the bearing inner ring, make the static-pressure system work between bearing inner ring and the axle, bearing inner ring floats on the axle; Gap between bearing housing and bearing inner ring input adhesive, treat that adhesive solidifies after, axle and bearing housing are pulled down from pedestal, promptly finished the assembling of dynamic and hydrostatic bearing.
The present invention is because the homogenization of static pressure oil film, and ring keeps each to the gap equalization with axle in the two bearings, so ring is all concentric with axle in the two bearings, and coaxial between just having guaranteed also that two bearings is interior and encircling; And, make the degree of symmetry of each oil groove also can be guaranteed because ring processing respectively in the two bearings makes means such as the oil groove in the bearing inner ring hole can cut with line, numerical control internal grinder process.With the dynamic and hydrostatic bearing precision height of assembly method of the present invention assembling, rational in infrastructure, shaft vibration is little.
Description of drawings
Fig. 1 is an assembly method schematic representation of the present invention.
Embodiment
As shown in Figure 1, a kind of assembly method of dynamic and hydrostatic bearing is characterized in that:
A, bearing housing 5 is fixed on the pedestal 1,
B, axle 3 two ends top 2 are withstood with axle, axle top 2 also is fixed on the pedestal 1;
C, process ring 4 in the two bearings, ring 4 in the two bearings is enclosed within respectively between axle 3 and the bearing housing 5, connect the oil circuit on the bearing inner ring 4, make the static-pressure system work between the bearing inner ring 4 and spools 3, bearing inner ring 4 floats on spools 3;
D, the gap between bearing housing 5 and bearing inner ring 4 input adhesive 6, treat that adhesive 6 solidifies after, axle 3 and bearing housing 5 are pulled down from pedestal 1, promptly finished the assembling of dynamic and hydrostatic bearing.
