Abstract
The invention discloses an adjustable oil deflector ring and an adjustment method thereof. The adjustable oil deflector ring comprises an oil-deflector ring arranged on the end surface of a bearing case, an inner hole and a rotor of an oil seal gear, and an adjustment screw arranged in each position at 45 degree angle to the vertical line of the lower half part of the oil-deflector ring. The adjustment method thereof comprises the following steps: positioning the upper and the lower half parts of the oil-deflector ring, tightening the upper and lower half parts by using a split surface bolt, initially positioning the oil-deflector ring on the bearing case by using a connection screw between the bearing case and the oil-deflector ring, adjusting the adjustment screws in the positions at 45 degree angle to the vertical line of the lower half part of the oil-deflector ring, and tightening the screws when the clearance between the inner hole of the oil deflector ring and the surface of the rotor meets the requirements. The invention has the advantages of easy operation, good effect, and convenience for field installation and adjustment.
Description
Technical field
The invention belongs to large-scale thermal power equipment and be used for bearing housing oil retaining part spare.
Background technique
Flinger ring is for being installed on the bearing housing, promptly be embedded in the bearing housing end face, the endoporus of its oil sealing tooth and the gap of rotor surface, when being installed, adjustment realizes (as shown in Figure 1 and Figure 2) by the repair or the cushioning of first split place adjustment piece, at last tightly on the bearing housing end face, it is bigger to adjust difficulty, makes troubles for on-the-spot the installation.
Summary of the invention
One of purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art part, designs to be easy to adjust, and brings adjustable easily flinger ring can for on-the-spot the installation.
Two of purpose of the present invention is to adopt this adjustable flinger ring to carry out the scene adjustment is installed.
The objective of the invention is such realization: on 45 ° position about second Vertical direction of flinger ring body, respectively add one and adjust screw, by adjusting the elongation of screw, change the radial position of flinger ring, make the endoporus of flinger ring and the gap, the left and right sides between rotor surface and after the gap reaches designing requirement up and down, again with flinger ring and bearing housing end face tight.
Described flinger ring body and bearing housing are tightly being that bolt by being circumference is connected.
It is after making second flinger ring in place earlier that described adjustable flinger ring carries out the on-the-spot method that adjustment is installed, with the split bolt with second is tight on it, attachment screw with bearing housing and flinger ring carries out the initial position flinger ring on bearing housing again, adjust 45 ° of locational adjustment screws about second Vertical direction of flinger ring, after the gap between flinger ring endoporus and rotor surface reaches requirement, the stressed joint screw is got final product.
Advantage of the present invention is: simple to operate, effective, and bring convenience for on-the-spot installation adjustment.

Embodiment
With reference to Fig. 1-Fig. 4, the present invention includes the flinger ring that is installed on the bearing housing end face, the endoporus of oil sealing tooth 14 and rotor 10 promptly respectively add one and adjust screw 5 on 45 ° position about second 4 Vertical direction of flinger ring body.
On the flinger ring body divides, following two halves, when last, following two halves flinger ring 2 and 4 in place after, to go up with split bolt 9, following two halves flinger ring 2 and 4 is tight, again with the attachment screw 7 first initial position flinger rings of bearing housing and flinger ring on bearing housing, attachment screw 7 is along circumference, 45 ° locational adjustment screw 5 about second 4 Vertical direction of adjustment flinger ring, by adjusting the elongation of screw, change the radial position of flinger ring, make the endoporus of flinger ring and the gap, the left and right sides 3 between rotor surface and after gap 3 reaches designing requirement up and down, again with flinger ring and bearing housing end face with attachment screw 7 tight.
Claims (3)
1. an adjustable flinger ring comprises the flinger ring that is installed on the bearing housing end face, and the endoporus of oil sealing tooth and rotor is characterized in that: respectively add one and adjust screw on 45 ° position about second Vertical direction of flinger ring body.
2. adjustable flinger ring as claimed in claim 1 is characterized in that: the flinger ring body is to be connected tight by the bolt that is circumference with bearing housing.
3. the adjusting method of an adjustable flinger ring is: after making second flinger ring in place earlier, with the split bolt with second is tight on it, attachment screw with bearing housing and flinger ring carries out the initial position flinger ring on bearing housing again, adjust 45 ° of locational adjustment screws about second Vertical direction of flinger ring, after the gap between flinger ring endoporus and rotor surface reaches requirement, the stressed joint screw is got final product.
