Abstract
The invention relates to a radially adjustable tiltable pad bearing, in particular relates to the tiltable bearing the pad of which is radially adjustable and belongs to the technical field of tiltable pad bearings. The radially adjustable tiltable pad bearing comprises a bearing body, bearing bushes and a bearing neck, wherein the outer end of each bearing bush is connected with the bearing body through a support pin; an angular contact rotation pair is formed between the front end of the support pin and the bearing bush; the rear end of the support pin is embedded in a pin body installing hole of the bearing body; adjusting washers are arranged between the support pin and the pin body installing hole. According to the radially adjustable tiltable pad bearing, radial adjustment can be realized by changing the thickness and amount of the adjusting washers, the machining accuracy requirement is lowered, machining and assembly are relatively simple and the manufacture cost is low; the stability requirement of the rotor with high speed and light load is met; the radially adjustable tiltable pad bearing is particularly suitable for a high speed vane wheel shaft of the centrifugal fan.
Description
Technical field
The present invention relates to a kind of radially adjustable tilting-pad bearing, 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 in the time of 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 complexity.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thereby a kind of radially adjustable tilting-pad bearing is provided, bearing shell can be adjusted to suitable position by adjusting pad, meet the stability requirement of high speed light loading lower rotor part, reduce tilting-pad bearing requirement on machining accuracy, assemble and process easy.
According to technological scheme provided by the invention, 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 multiple along the circumferential direction equally distributed bearing shells, bearing shell is inner to be contacted 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 present invention has the following advantages:
The present invention 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 changeing, 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.
