Abstract
The utility model relates to an alloy straightener bearing, which is particularly used for fittings of a steel cord straightener and belongs to the technical field of the steel cord straightener. The alloy straightener bearing comprises outer rings, inner rings, outer alloy sheaths, rolling elements, dust rings, first retainers and second retainers, wherein the rolling elements are connected with the outer rings and the inner rings and positioned with the first retainers and the second retainers; the retainers uniformly isolate the rolling elements to keep clearances and ensure concentricity; each dust ring is placed into a dust groove of each outer ring to form a set of bearing assembly; the outer alloy sheaths are arranged on the outer rings of the two sets of bearing assemblies in an embedding manner and are combined and connected with the two sets of bearing assemblies into a whole. The radial carrying capacity of the steel cord straightener bearing can be increased, and the service life of the steel cord straightener bearing can be prolonged, so that the non-abrasive failure of the bearing is avoided, the rated service life of the bearing is ensured, and the utilization ratio of the product is increased.
Description
Technical field
The utility model relates to a kind of alloy Straightener bearing, specifically is used for steel cord Straightener, belongs to steel cord industry Straightener accessory technical field.
Background technique
At present, the deep groove ball bearing that is used on the steel cord Straightener mainly is made up of outer ring, inner ring, retainer, retainer, rolling element, dust ring, lubricating grease etc.Be employed between outer ring and the inner ring rolling element is installed, with retainer location, even separation roller of retainer and maintenance rolling element proper exercise; Dust ring is put in the dustproof groove of outer ring, plays dustproof and prevents that grease from leaking outside, the lubricating grease lubricate; Purpose is to make to form the very thin oil film of one deck between bearing element face and slip surface; Preventing that metal from directly contacting with metal, thereby reduce bearing internal friction and wearing and tearing, prevent to burn sticking.When this kind bearing is assemblied on the workpiece; Bear big radial load; Steel cord aligning be through be fixed on aligning bearing on the straightening plate form about, high infraversion malposition eliminates pressure to steel cord aligning; The quality that the leveling effect of Straightener directly determines the steel cord in addition bearing the outer ring also the friction of invar cord surface abrasion is strengthened, make bearing failure.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; Thereby a kind of optimization design bearing structure is provided; Increase the wear resistance of bearing outer ring; Can effectively improve the bearing capacity of bearing, improve bearing and lost efficacy in advance, thereby guarantee the steel cord Straightener bearing that bearing and whole parts proper functioning turn round.
The technological scheme that provides according to the utility model; A kind of alloy Straightener bearing comprises outer ring, inner ring, outer alloy cover, rolling element, dust ring, first retainer and second retainer; Said rolling element connects outer ring and inner ring; And with first retainer and second retainer location, the even separation roller of retainer keeps the gap and guarantees concentricity, in the dustproof groove of outer ring, puts into dust ring and forms a cover bearing unit; Outer alloy cover is embedded on the outer ring of two cover bearing uniies, and two cover bearing uniies are connected into one.
Compared with present technology the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Under the prerequisite that guarantees steel cord Straightener bearing torque demand, improve bearing structure; Increased outer alloy cover; Improved steel cord Straightener bearing radially to bearing capacity, increased the working life of steel cord Straightener bearing, thereby avoided the non-abrasiveness of bearing to lose efficacy; Guarantee the specified working life of bearing, improved the utilization ratio of product.
Description of drawings
Fig. 1 is the utility model bearing structure schematic representation.
Embodiment
Following the utility model will combine the embodiment in the accompanying drawing to further describe:
As shown in Figure 1, comprise outer ring 1, inner ring 2, outer alloy cover 3, rolling element 4, dust ring 5, first retainer 6 and second retainer 7.
The utility model steel cord Straightener bearing adopts rolling element 4 connection outer rings 1 and inner ring 2; And with first retainer 6 and second retainer, 7 location, even separation roller 4 of retainer and maintenance rolling element proper exercise keep the gap and guarantee concentricity; And keep rolling element steady in a long-term to turn round; In the dustproof groove of outer ring 1, put into dust ring 5, in outer ring 1 and inner ring 2, inject grease and form a cover bearing unit, outer alloy cover 3 is embedded in two and overlaps on the outer ring of bearing uniies; And with two the cover bearing uniies be connected into one, can improve the hardness and the wear resistance of peripheral groove like this.Said two cover bearing unit structures are identical.
The utility model can effectively stop the bearing leakage that grease may occur in running up, and it is inner to have guaranteed not have foreign material to get into bearing simultaneously.Utilize two cover bearings to cooperate outer alloy cover to form the Straightener assembly bearing, well guaranteed the working life of bearing simultaneously.
