Abstract
The utility model relates to an anti-wear bearing retainer, comprising a retainer body. The retainer body comprises an alloy steel substrate which is provided with a groove, and the surface of the alloy steel substrate and the surface of the groove are respectively coated with a ceramic coating. The anti-wear bearing retainer has good inner toughness and high surface strength, adopts alloy steel replacing copper as the retainer substrate, and is beneficial to reducing the manufacturing cost.
Description
Technical field
The utility model relates to a kind of retainer, especially relates to a kind of anti-wear bearing retainer.
Background technique
The main bearing of blower fan is the critical component of wind-driven generator, and its safe and reliable operation is directly connected to the performance of whole blower fan, and will guarantee bearing energy safe and reliable operation, must guarantee that then bearing obtains good lubricating in running; Usually lubricant medium is very responsive to impurity, and a spot of metal granule all might cause the reduction of lubricant medium performance, and therefore the wearing and tearing that reduce between each metal parts are particularly important.Existing blower fan main shaft holds the copper cage often of use, and the copper powder that produces in its running can make the greasy property of lubricant medium significantly reduce; In addition, the manufacture cost height of copper cage accounts for more than 30% of bearing assembly basis.
The model utility content
In order to overcome the above-mentioned defective that prior art exists, the utility model provides a kind of low cost of manufacture, can not produce the main bearing retainer that resistance to wears of poisonous metal powder in the bearing running.
The technical solution of the utility model is: it comprises the retainer body, and described retainer body comprises the alloyed steel matrix, and the alloyed steel matrix is provided with groove, and alloyed steel matrix surface and groove surfaces all are coated with one deck ceramic coating.
The preferred 100-200 μ of the thickness of described ceramic coating m.
When bearing in when operation because the effect of groove, help avoiding contacting of generation face and face between retainer and the bearing; Along with the injection of lubricant medium, help between retainer and bearing, forming oil film; Ceramic coating makes the metalwork of retainer and bearing surface separate, and the friction factor of ceramic coating is little, thereby helps reducing the friction between retainer and the race ring, reduces the generation of metallic dust, helps guaranteeing the bearing safe and reliable operation.
The utility model internal toughness is good, the surface strength height; Adopt the alloyed steel Alloy instead of Copper as the retainer matrix, help reducing manufacture cost.
Description of drawings
Fig. 1 is the utility model example structure schematic representation;
Fig. 2 is retainer of the utility model and the schematic cross-section after the bearing assembling.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
With reference to accompanying drawing, present embodiment comprises retainer body 5, and described retainer body 5 comprises alloyed steel matrix 4, and alloyed steel matrix 4 is provided with groove 2, and alloyed steel matrix 4 surfaces and groove 2 surfaces all are coated with one deck ceramic coating 3.
The thickness of described ceramic coating 3 is 120 μ m.
When bearing 1 in when operation, because the effect of groove 2, help avoiding contacting of generation face and face between retainer 5 and the bearing 1, injection along with lubricant medium, help between retainer 5 and bearing 1, forming oil film,, thereby help reducing friction between retainer 5 and the lubricant medium again because the friction factor of ceramic coating 3 is little, do not influence the greasy property of lubricant medium, guarantee the operation that bearing can be safe and reliable.
