Abstract
The utility model relates to a radial-direction-adjustable tilting pad bearing, particularly relates to a radial-direction-adjustable tilting pad bearing for a pad block of a centrifugal fan and belongs to the technical field of tilting pad bearings. The tilting pad bearing comprises a bearing body, bearing bushes and a bearing neck, wherein the outer end of each bearing bush is connected with a bearing body through a support pin; the front end of each support pin and the corresponding bearing bush form a spherical contact rotating pair; the rear end of each support pin is embedded in a pin body installing hole; adjusting gaskets are arranged between each support pin and the corresponding pin body installing hole. According to the radial-direction-adjustable tilting pad bearing, during installing, the radial adjustment on the bearing bushes can be realized by adjusting the thicknesses and the number of the adjusting gaskets; the machining accuracy requirement is lowered; the machining and the assembling are relatively simple; the manufacturing cost is low; the stability requirement of a rotor on high speed and light load can be met; the radial-direction-adjustable tilting pad bearing is particularly suitable for a high-speed blade shaft of the centrifugal fan.
Description
Technical field
The utility model relates to a kind of radially adjustable tilting-pad bearing, and specifically the radially adjustable tilting-pad bearing of a kind of tile fragment for centrifugal blower, belongs to the pad bearing technical field of inclining.
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, is mainly 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 current tilting-pad bearing, axially locating adopts screw or straight pin to locate more, cannot realize radial regulation.Make requirement on machining accuracy higher, processing technology is complicated.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of radially adjustable tilting-pad bearing, by adjusting pad, bearing shell can be adjusted to suitable position, meet the stability requirement of high speed light loading lower rotor part, reduce tilting-pad bearing requirement on machining accuracy, assemble and process easy.
The technological scheme providing according to the utility model, radially adjustable tilting-pad bearing comprises bearing support, bearing shell and axle journal, axle journal is positioned at bearing support inner ring central position, between axle journal and bearing support, be provided with a plurality of along the circumferential direction equally distributed bearing shells, bearing shell the inner contacts with necked part by smooth arc surface, it is characterized in that: each bearing shell outer end is by a rest pin connection bearing body, between rest pin front end and bearing shell, form the revolute pair of sphere-contact, rest pin rear end embeds in the shank mounting hole of bearing support, between rest pin and shank mounting hole, be provided with adjustment pad.
Further, be provided with gap X between bearing shell and axle journal, X scope is 0.06 mm ~ 0.1mm.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, rationally, the radial regulation when being adjusted the thickness of pad and quantity and realized bearing shell and install by changes, reduces requirement on machining accuracy, processing and assemble easier, low cost of manufacture; Can meet the stability requirement of high speed light loading lower rotor part, be particularly useful for the quick runner axle of centrifugal blower.
Accompanying drawing explanation
