Abstract
The utility model discloses a guide vane bearing, comprising a double-way connecting screw rod. The guide vane bearing is characterized in that: two ends of the double-way screw rod are respectively connected with two tight knot pieces; each tight knot piece consists of an inner ring rod head of an outer spherical surface and an outer ring rod head of an inner spherical surface; an axel journal head of the inner ring rod head has out screw threads and is provided with a mounting nut; an axel journal head of the outer ring rod head has outer screw threads; and the two spherical surfaces are in small clearance fit and are fixed through a clamping sleeve. The guide vane bearing has larger bearing capacity and impact-resistant capacity, and has the characteristics of corrosion resistance, abrasion resistance, self alignment, self lubrication and scale resistance, thereby achieving a structure which can transmit larger torque and is firm on the whole. Moreover, the guide vane bearing can be applicable to a guide vane transmission structure in the turbomachinery field, fulfill the aim of transmitting the higher torque under smaller angular deflection, and is convenient to be installed, compact in structure and suitable to be popularized.
Description
Technical field
The utility model belongs to the turbomachinery field, is specifically related to a kind of guide vane bearing, is used for the compressor vanes transmission, realizes the mechanical transmission to compressor vanes.
Background technique
Existing plain bearing is made of closed type race ring and ball rack etc. usually, can't be installed in the stator drive bearing that is used for the turbomachinery field.
Summary of the invention
The purpose of this utility model is, a kind of guide vane bearing is provided, and this guide vane bearing can be installed on the rotating shaft connecting rod of stator easily, thereby realizes the transmission to the high pulling torque power under the small angle rotation of stator.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of guide vane bearing, comprise a two-way connecting screw rod, it is characterized in that, the two ends of this two-way connecting screw rod are connected with two movable joint spares respectively, and described movable joint spare is made up of the inner ring bar head of an outer spherical surface and the outer ring bar head of an inner ball surface, is outside thread on the inner ring bar head axle journal head, and have an installation nut, and be internal thread on the bar head axle journal head of outer ring, two spheres are assembled by little Spielpassung, and fix with cutting ferrule.
Guide vane bearing of the present utility model has bigger bearing capacity and impact resistance, and have anti-corrosion property, wear resistance, from the characteristics of aligning, selflubricating, anti-dirt, can transmit high torque, firm structure generally thereby reach.Can be applied in the stator drive mechanism of turbomachinery field, realize transmitting under the less situation of angular deflection purpose than high pulling torque, and easy for installation, compact structure, the suitable popularization.
Description of drawings
Fig. 1 is a guide vane bearing structural representation of the present utility model;
Fig. 2 is the guide vane bearing scheme of installation; Wherein (a) is that guide vane bearing is fixed on by being threaded on the stator transmission group, (b) is fixing rear guide vane bearing movable schematic representation;
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment
Referring to accompanying drawing, the utility model guide vane bearing is divided into attachable three parts, and promptly two movable joint spares 2 and a two-way connecting screw rod 3 are formed.
Movable joint spare 2 mainly is made up of the inner ring bar head of an outer spherical surface and the outer ring bar head of an inner ball surface, is outside thread 4 on the inner ring bar head axle journal head, and the band same specification is installed nut 1, and is internal thread on the bar head axle journal head of outer ring, so that be connected with two-way connecting screw rod 1.Two spheres are assembled by little Spielpassung, and fixing with cutting ferrule 5, and are firm to guarantee the location.
Two-way connecting screw rod 3 two ends are the bidirectional helicals that match with movable joint spare 2, and are with fixing pin that three parts are locked fully behind movable joint spare 2 and two-way connecting screw rod 3 mount good positions, guarantee fastening.
Guide vane bearing of the present utility model is fixed on (shown in Fig. 2 a) on the stator transmission group by being threaded, the function of finish transmission, regulating stator.
Guide vane bearing of the present utility model has bigger bearing capacity and impact resistance, and has anti-corruption The property, wearability, Self-aligning, self-lubricating, anti-dirt characteristics, thereby reach can transmit high torque, Firm structure generally.
