Abstract
The invention relates to a method for fixing a thrust bearing ring, which is suitable for fixing the thrust bearing ring in a precise rotating shaft system on a bearing seat. The bearing pedestal has the advantages that the thrust bearing ring can be fixed on bearing pedestals made of materials with different expansion coefficients, mutual influence caused by mutual deformation is small when the environmental temperature changes, and the precision of a rotary shaft system is guaranteed. The thrust bearing ring is positioned on the mounting surface of the bearing seat through the three radial positioning blocks; in a plurality of through-holes of the radial edge circumference equipartition of thrust bearing ring, the embedding compresses tightly the cover, and the screw through penetrating the compression cover is spacing with the thrust bearing ring along the axial, makes the connection face of thrust bearing ring just laminate with the installation face of bearing frame. Gaps are reserved among the radial positioning blocks, the pressing sleeve and the thrust bearing ring, so that the thrust bearing ring can freely expand and contract when the temperature changes.
Description
Technical field
The present invention relates to the fixation method of the collar of thrust bearing in rotary axis, particularly a kind of fixation method of the collar of thrust bearing.
Background technique
In order to guarantee the running accuracy of electro-optic theodolite vertical shaft series, the planeness of the collar of thrust bearing roller surface in the axle system there is higher required precision.Generally be to be fixed on the collar of thrust bearing on the bearing support of cast iron or cast steel, because the collar of thrust bearing and bearing support expansion coefficient basically identical are when variation of ambient temperature, less to the influence of the collar of thrust bearing.And in order to alleviate weight of equipment; The material selection cast aluminium of bearing support, so just exist the collar of thrust bearing be fixed on the inconsistent material of the expansion coefficient of the collar of thrust bearing on, when bigger variation takes place in ambient temperature; Because the distortion of the collar of thrust bearing and bearing support is inconsistent; Cause the collar of thrust bearing to deform, influence the running accuracy of axle system, and then influence the measuring accuracy of electro-optic theodolite.
Summary of the invention
The object of the invention just provides a kind of fixation method of the collar of thrust bearing; Use so that the collar of thrust bearing is fixed on the bearing support of processing with the expansion coefficient material different of the collar of thrust bearing; When ambient temperature changes; Inconsistent to cause the collar of thrust bearing to deform less by the distortion of the collar of thrust bearing and bearing support, makes rotary axis have lower temperature sensitivity.
The fixation method of a kind of collar of thrust bearing provided by the invention, through three radial location pieces, with the collar of thrust bearing in the enterprising conduct of the attachment face of bearing support to the location; In a plurality of through holes that are uniformly distributed along the circumference of the collar of thrust bearing, embed clamping sleeve, through the screw that penetrates clamping sleeve that the collar of thrust bearing is spacing vertically, the junction surface of the collar of thrust bearing and the attachment face of bearing support are just fitted; Radial location piece and clamping sleeve all and gapped between the collar of thrust bearing make the collar of thrust bearing when temperature changes, and can freely stretch.
At the described collar of thrust bearing, open three equally distributed flutings at circumferencial direction, fluting has the bi-side that are parallel to each other, and the fluting direction is along the collar of thrust bearing radially; On the circumference of certain radius, be uniformly distributed with a plurality of through holes.
At described radial location piece,, guarantee that the gap is 0.002～0.004mm with collar of thrust bearing fluting side surfaces contacted; With the collar of thrust bearing an amount of gap radially arranged, when ambient temperature changed, the radial location piece did not interfere with the collar of thrust bearing.
At described clamping sleeve, it has an amount of gap with the through hole of the collar of thrust bearing on diametric(al), and when ambient temperature changed, clamping sleeve did not interfere with collar of thrust bearing through hole; Its length guarantees behind the screw pretension than the long 0.01～0.02mm of the through hole of the collar of thrust bearing, the junction surface of the collar of thrust bearing and the attachment face of bearing support is just fitted.
At the junction surface of the described collar of thrust bearing and the attachment face of bearing support, its planeness is less than 0.01mm.
The fixation method advantage of this collar of thrust bearing of the present invention: 1) simple and reliable for structure, it is convenient to implement; 2) can be fixed on the bearing support with the different expansion coefficient material of the collar of thrust bearing the collar of thrust bearing; Again can be when ambient temperature changes; Influencing each other that distortion causes each other is little, guarantees the precision of rotary axis, makes rotary axis have lower temperature sensitivity.
