Abstract
An integrated bearing holder is mainly characterized in that: a rivet post which has one end integrated with the top of the supporting beam of the holder and is in parallel with the supporting beam is arranged on top of each supporting beam of the holder, the rivet posts are arranged in the corresponding through holes on the holder cover, and the other end of each rivet post is riveted on the holder cover. The utility model can reduce defective index and comprehensive production cost, and greatly improves production efficiency, the service life, the revolution precision, the rated load and the integral bearing capacity of the bearing.
Description
Technical field the utility model relates to the retainer of a kind of rolling bearing, particularly rolling bearing.
Background technique is present, the retainer of roller bearing is generally by keeping stand, retainer lid and rivet three parts to form, promptly in each the pillar beam that keeps stand, be provided with through hole in parallel, these through holes are corresponding with the through hole that retainer covers again, are equipped with a rivet that both are riveted together keeping stand and retainer to cover in the through hole of every group of correspondence.Its deficiency is: boring the time causes the skew in hole easily on (1) retainer seat beam, thereby causes the retainer reject rate high, not only waste of manpower and equipment, and increased the cost of production of bearing; (2) because rivet is little, processing is difficulty relatively, so reject rate is also very high, equally also increases the cost of production of bearing; (3) because rivet is little, and positive pressure is big again during riveted, easily produce the riveted distortion, influence the comprehensive quality and the working life of bearing; (4) rivet must be installed by hand, and labor intensity is big, and manufacturing efficiency is low; (5) mould therefor complex structure, the manufacture cost height; (6) this structure retainer is owing to connect by rivet, and rivet head has certain elongation, when the bearing integral physical dimension is determined, influenced the effective length of roller, rivet hole on the retainer seat beam has limited the assembling number of roller simultaneously, thereby define the load rating of bearing, greatly influenced the comprehensive usability of bearing, (7) bearing is being hit, under the vibration and the applying working condition of alternating stress, rivet is kept stand and the retainer lid shearing force that relative movement produced bigger, thus the retainer lid is easy and body portion from, thereby cause early stage damage, and influence the whole service life of bearing owing to retainer.
The summary of the invention the purpose of this utility model is to provide a kind of comprehensive quality and the working life that can not only improve bearing, and the integrated bearing retainer that can also enhance productivity and reduce cost.The utility model mainly is by the retainer lid and keeps stand dimerous.Be equipped with on each the pillar beam-ends top that keeps stand wherein that an end is connected as a single entity with it and with the riveted post of pillar Liangping row.Best, this riveted post is located at pillar beam-ends top center, the i.e. central lines of the center line of riveted post and pillar beam.These riveted posts are positioned at retainer again and cover the through hole corresponding with them, and the other end is riveted on retainer and covers.
The utility model has following advantage compared to existing technology: (1) has saved many manufacturing procedures, has not only improved manufacturing efficiency, has also reduced comprehensive cost of production.(2) eliminate the shearing force that keeps stand and lid relative movement that the link between them is produced, thereby improved the working life and the comprehensive usability of bearing.(3) assembly quality is good, and binding site is solid and reliable, and riveted joint back retainer does not produce distortion, can improve the bearing rotating accuracy greatly like this, can improve load rating 25%.(4) can dwindle the shared space of pillar beam, can in the useful space, increase the number of roller, improve the comprehensive load capacity of bearing; (5) can make link and maintenance stand, lid homogeneity, eliminate because of the expansion coefficient difference causes the rivet fracture and made the problem of bearing reduction in working life.(6) reduced reject rate about 35% in the retainer course of working.
