Abstract
The utility model relates to a broken tiles fixing structure of a tilting-pad bearing. The broken tiles fixing structure of the tilting-pad bearing comprises a bearing body, bearing pads, a shaft neck, end covers, fixing pins and bolts, wherein the bearing pad is placed between the bearing body and the shaft neck, the end covers are fixing at two sides of the bearing body through the bolts, a small hole is drilled in each end cover, the fixing pins are embedded in the small holes, and the bearing pads are located in a radial direction through the fixing pins at two ends of the bearing body. Gaps are axially formed between the end covers and the bearing pads, and the bearing pads can be effectively and axially located due to the fact that reasonable gaps are arranged. Gaps are formed between the bearing pads and the shaft neck. The broken tiles fixing structure of the tilting-pad bearing has the advantages of being simple, compact and reasonable in structure, simple in processing and assembly, convenient to process and assemble, low in manufacturing cost, capable of meeting requirements of stability of a rotor under the high speed and light load, and particularly suitable for a high speed impeller shaft of a centrifugal fan.
Description
Technical field
The utility model relates to a kind of tile fragment fixed structure of tilting-pad bearing, and specifically a kind of tile fragment of the tilting-pad radial bearing for centrifugal blower is fixed, and belongs to the mechanical structure technical field.
Background technique
The tile fragment of tilting-pad radial bearing can be adjusted its gradient automatically with the variation of load, speed, is the best bearing type of stability, mainly is applicable to the operating mode of high speed light loading.The rotating speed of centrifugal blower is higher, and tilting-pad bearing can form best oil film when working conditions change, and good anti-vibration is not easy to produce oil whip.
The tile fragment of present tilting-pad radial bearing, axially locating adopts screw to locate more.Need to drive a positioning hole at a watt back, and open a tapped through hole in the oil groove of bearing support.Screw screws in tapped through hole, then enters the positioning hole of watt back of the body, realizes in such a way the axially locating of tile fragment.Such mode is assembled complexity, processes more loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of tile fragment fixed structure of tilting-pad bearing is provided, and this is simple and reasonable, assembles and process easy, can satisfy the stability requirement of high speed light loading lower rotor part, be particularly useful for the quick runner axle of centrifugal blower.
According to the technological scheme that the utility model provides, a kind of tile fragment fixed structure of tilting-pad bearing comprises bearing support, bearing shell, axle journal, end cap, fixing pin and screw, and described bearing shell is between bearing support and axle journal.Described end cap is fixed by screws in bearing support both sides, is drilled with aperture on end cap, aperture embedded fixing pin, bearing shell carries out radial location by the fixing pin at two ends.Described end cap and bearing shell are Y axially being provided with the gap, and Y arranges and can carry out effective axially locating to bearing shell by rational gap between 0.5mm to 1mm.
As a further improvement on the present invention, described bearing shell is the great circle arc that radius is R on axial plane, and R is not less than 800mm.
As a further improvement on the present invention, be provided with gap X between described bearing shell and axle journal, and X is between 0.06-0.1mm.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable; Processing is easier with assembling, low cost of manufacture; Can satisfy the stability requirement of high speed light loading lower rotor part, be particularly useful for the quick runner axle of centrifugal blower.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is the A-A view of Fig. 1.
Embodiment
Following the utility model embodiment is further described in connection with accompanying drawing:
As shown in Figure 1 and Figure 2: the present embodiment comprises bearing support 1, bearing shell 2, axle journal 3, end cap 4, fixing pin 5 and screw 6, and described bearing shell 2 is between bearing support 1 and axle journal 3.Described end cap 4 is fixed on bearing support 1 both sides by screw 6, is drilled with aperture on end cap 4, aperture embedded fixing pin 5, bearing shell 2 carries out radial location by the fixing pin 5 at two ends.Described end cap 4 is Y with bearing shell 2 axially being provided with the gap, and Y arranges and can carry out effective axially locating to bearing shell by rational gap between 0.5mm to 1mm.The outside of bearing shell 2 is the great circle arc that radius is R on axial plane, described radius R is not less than 800mm; Be provided with gap X between bearing shell and axle journal, and X is between 0.06-0.1mm.
When rotor journal 3 rotates, bearing shell 2 can compensate rotor journal in axial inclination by the swing of circular arc R in axial plane in the outside, make oil film wedge thickness remain at state comparatively uniformly in axial distribution, simultaneously, because bearing shell 2 is less with the gap of axle journal 3, relatively reduce the radial vibration of rotor journal 3, improved the working stability of rotor.
Prove through repetition test, when the utility model was used for driving the impeller shaft of high-speed centrifugal fan, the working stability of rotor can meet design requirement fully.
