Background technology
In the assembling process of generator, the bearing of high-hardness is installed on generator rotor shaft, before bearing Fan blade is mounted directly on the armature spindle at end, the rear end of bearing is also directly to be contacted with generator housing.Since fan blade is aluminum Fan blade, such assembling structure of fan blade and bearing, the bearing inner race of high-hardness and the aluminum fan blade of soft material It being in direct contact, the contact surface of aluminum fan blade can be extruded slight recess by bearing inner race, in generator high speed rotation, the recess It can constantly deepen, so that fan blade is suspended to the sealing ring of bearing, ultimately cause bearing damage, the failures such as fan blade abrasion substantially reduce The service life of bearing and fan blade, while to client's later maintenance causing big inconvenience.
Invention content
The technical problem to be solved by the present invention is to the above-mentioned deficiencies for the prior art, provide a kind of simple in structure, processing It is convenient, it can effectively avoid aluminium fan blade and the new-generation machine bearing and aluminium fan blade assembling structure of bearing damage.
The technical scheme is that such:A kind of assembling structure of dynamo bearing and aluminium fan blade, including generator Ontology, the shaft front end of the engine block are equipped with bearing and aluminium fan blade successively, on the engine block of the bearing side Equipped with the positioning region for limiting bearing axial displacement, the positioning region includes annular limit that is parallel with bearing face and contacting Plane and convolution face perpendicular to the annular stop face are equipped with outer ring radial dimension in the through-hole being made of the convolution face The installation axle of fan blade washer compatible with the aluminium fan blade installation axle, the aluminium fan blade is plugged in the through-hole and compresses The fan blade washer.
As a further improvement, the outer ring radial dimension value of the fan blade washer is in the installation axle of the aluminium fan blade Between diameter and the range of outer diameter.
Further, the outer ring radial width of the fan blade washer is equal with the installation axle outer diameter of aluminium fan blade.
Further, the thickness of the fan blade washer be less than the convolution face width, i.e., the described fan blade washer it is recessed in In the through-hole.
Further, the fan blade washer is between the aluminium fan blade and bearing, in the engine block Fan blade washer is additionally provided between bearing to connect with the engine block.
Further, the fan blade washer is formed by the 65Mn casts of high rigidity.
Advantageous effect
Compared with prior art, the present invention having the advantage that:Fan blade washer, aluminum are added between bearing and aluminum fan blade The pressure that fan blade is subject to is transmitted to by fan blade washer on bearing, is thoroughly solved bearing inner race and is collapsed wind caused by aluminum fan blade The problem of leaf abrasion, bearing damage;Its fan blade washer is made of the 65Mn materials of high rigidity, substantially increases the wear-resisting of washer Property, effectively extend the service life of washer;The thickness of its fan blade washer is less than the length in convolution face, can be the installation of aluminium fan blade Axis provides space as positioning, and the radial width of fan blade washer is equal with the outer diameter of aluminium fan blade, effectively avoids installation fan blade pad It is interfered when circle.
Description of the drawings
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the structural schematic diagram of engine block in the present invention.
Wherein:1- engine blocks, 2- bearings, 3- aluminium fan blade, 4- fan blades washer, the positioning regions 11-, 12- annular stops face, 13- convolutions face, 14- through-holes.
Specific implementation mode
The present invention is described further for specific embodiment in below in conjunction with the accompanying drawings.
Refering to fig. 1-2, the assembling structure of a kind of dynamo bearing and aluminium fan blade of the invention, including engine block 1, The shaft front end of engine block 1 is equipped with bearing 2 and aluminium fan blade 3 successively, is equipped with and uses on the engine block 1 of 2 side of bearing In the positioning region 11 of limitation 2 axial displacement of bearing, can not only it play screens to bearing 2, but also the rigid of engine block 1 can be improved Property, enough installation spaces are provided for 3 installation axle of aluminium fan blade, which includes ring that is parallel with 2 end face of bearing and contacting Shape confined planes 12 and convolution face 13 perpendicular to the annular stop face 12 are equipped in the through-hole 14 being made of its convolution face 13 The installation axle of the fan blade washer 4 that outer ring radial dimension is adapted to 3 installation axle of aluminium fan blade, aluminium fan blade 3 is plugged in through-hole 14 simultaneously Compress fan blade washer 4;Its fan blade washer 4 is between aluminium fan blade 3 and bearing 2, and between engine block 1 and bearing 2 Fan blade washer 4 is additionally provided with to connect with its engine block 1.The assembling structure of the present invention, by engine block 1 and bearing 2 Between and the alternator shaft between bearing 2 and aluminium fan blade 3 on add fan blade washer 4, can avoid engine block 1 and aluminium wind High-speed friction between leaf 3 and bearing 2 causes to damage engine block 1, aluminium fan blade 3 and bearing 2, substantially prolongs generator Service life.
The outer ring radial dimension value of fan blade washer 4 in the present invention is between the installation axle internal diameter of aluminium fan blade 3 and the model of outer diameter Enclose interior value, it can be ensured that fan blade washer 4 smoothly penetrates in the through-hole 14 of engine block 1, and ensures the installation axle of aluminium fan blade 3 It being tightly attached on fan blade washer 4, it is preferred that the outer ring radial dimension of its fan blade washer 4 is equal with the installation axle outer diameter of aluminium fan blade 3, And the outer diameter tolerance of its fan blade washer 4 ranging from -0.1mm~0mm is ensuring that fan blade washer 4 is smoothly inserted in engine block 1 Through-hole 14 when, it is ensured that the installation axle of aluminium fan blade 3 is stuck in completely on fan blade washer 4, prevent aluminium fan blade 3 installation axle wear simultaneously It is recessed into and rubs with bearing 2;The thickness of its fan blade washer 4 be less than its circle round face 13 width degree, i.e., fan blade washer 4 it is recessed in In through-hole 14,14 inner wall of through-hole forms positioning between part and the installation axle outer wall of aluminium fan blade 3 beyond fan blade washer 4, can be The installation axle of aluminium fan blade 3 provides installation space, is conducive to the location and installation of aluminium fan blade 3, the installation axle of aluminium fan blade 3 is avoided to be exposed at power generation The outer surface of machine ontology 1, the phenomenon that causing aluminium 3 fluctuation of service of fan blade, it is preferred that its fan blade washer 4 is using high rigidity 65Mn casts form, and increase the intensity of fan blade washer 4, to improve the wearability of fan blade washer 4, substantially prolong The service life of generator.
What has been described above is only a preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, Without departing from the structure of the invention, several modifications and improvements can also be made, these all do not interfere with implementation of the present invention Effect and patent practicability.
