Abstract
The utility model belongs to the bearing cage technology. A low noise bearing cage with compact nails proposed comprises an upper cage, a lower cage and a rivet comprising two parts of a hob nail cap and a nail body which comprises four columns of different diameters. The lower end of the nail body is the first gradual expand diameter segment, and the transition section of the nail body and the rivet hole of the cage have a clearance fit. The second gradual expand diameter segment on the upper part of the transition section and the rivet hole of the cage expand the diameter form the clearance fit to an interference fit, and the highest end of the nail body is an interference fastening segment, which together with the rivet hole of the cage has the interference fit. The interference fastening segment of the rivet is tightly inserted into the rivet hole of the upper tablet cape and has the interference fit, and the rivet hole of the lower tablet cage is combined with the second gradual expand segment and the transition section of the rivet. The cage structure proposed by the utility model effectively ensures the ball pocket clearance of the cage, reduces the bearing noise, and meanwhile meets the requirement of the automatic assembly.
Description
(1) technical field:
The utility model belongs to the retainer technology, mainly proposes the low noise bearing retainer that a kind of band is marked closely.
(2) background technique:
Along with the continuous development of new and high technology, all kinds of main frames develop towards high-performance, low noise direction, and this just needs reliable performance, the life-span is long, precision is high low noise motor bearings supporting.Bearing industry is improving precision that focusing on of bearing quality improve medium and small deep groove ball bearing, reduce vibrating noise, improving on working life.In research and development noise reduction problem, only work hard at the manufacture view of bearing steel ball and inside and outside cover, adopt sophisticated equipment and technology, the raceway groove and the steel ball machining accuracy of inside and outside lasso reached certain level, but the noise problem that bearing exists still can not get basic solution.Mentioned on the schedule of bearing noise reduction as the retainer of one of bearing four big parts thus.Medium and small deep groove ball bearing retainer in using now adopts common cylinder rivet, be only applicable to " pine nail " technique for riveting of artificial plug pin, rivet hole is greater than rivet diameter, by artificial plug pin, promptly waste time and energy, there is the micro-play phenomenon after bearing assembles again, produce noise and different sound in the bearing operation, influence bearing quality, more can not adapt to the automation assembling of bearing, the play standard that influence is set.
(3) summary of the invention:
The purpose of this utility model promptly is to propose the low noise bearing retainer that a kind of band is marked closely, and makes its structural design can eliminate the micro-play phenomenon that existing retainer structure exists, thereby effectively reduces the bearing noise, and adapt to bearing automation assembling.
The utility model is finished the technological scheme that its invention task proposed: its rivet of the retainer of proposition has fastening section of gradually extension diameter section, changeover portion and interference and rivet and retainer is connected to form and carries tacked constructions; Rivet comprises the tack head of a nail and nail body two-part, the nail body partly has four sections cylinders that diameter is different, the nail body is first extension diameter section gradually bottom, think that the nail body enters in the rivet hole of retainer smoothly, the rivet hole Spielpassung of nail body changeover portion and retainer, the top of changeover portion is second extension diameter section gradually, with the rivet hole of retainer by Spielpassung to the interference fit hole enlargement; The top of nail body is fastening section of interference, the rivet hole interference fit of itself and retainer; Fastening section interior and rivet hole interference fit of rivet hole of tightly inserting a retainer of the interference of rivet, the rivet hole of following sheet retainer and rivet second gradually extension diameter section and changeover portion combine, because the second gradually upper end and the rivet hole interference fit of extension diameter section, assembling back lab retainer also is the drive fit state, constitutes the rivet arrangement that carries of retainer.
Its rivet of the retainer that the utility model proposes and rivet hole interference fit, can effectively overcome the micro-play phenomenon that retainer " pine nail " technique for riveting exists, can guarantee effectively that thereby retainer ball pocket play reduces the bearing noise, simultaneously two of its nail body partial design gradually extension diameter section and changeover portion can make it adapt to the requirement of automation assembling, its structure that carries rivet can improve the efficiency of assembling of retainer and bearing, adapts to the automation assembling especially.
(4) description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model retainer rivet arrangement schematic representation.
Accompanying drawing 3 is retainer and rivet assembly structure schematic representation.
Among the figure, 1-last slice retainer, 2-rivet, 3-following sheet retainer, 4-ball pocket, 5-tack head of a nail, fastening section of 6-interference, 7-the second extension diameter section gradually, 8-changeover portion, 9-the first extension diameter section gradually.
(5) embodiment:
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
Shown in accompanying drawing 1,2,3, its rivet 2 of the retainer of proposition has fastening section of gradually extension diameter section, changeover portion and interference and rivet and retainer is connected to form and carries tacked constructions.Shown in accompanying drawing 2,3, rivet 2 comprises the tack head of a nail 5 and nail body two-part, and the nail body partly has four sections cylinders that diameter is different, and the nail body is first extension diameter section 9 gradually bottom, thinks that the nail body enters in the rivet hole of retainer smoothly.The rivet hole Spielpassung of nail body changeover portion 8 and retainer.The top of changeover portion is second extension diameter section 7 gradually, with the rivet hole of retainer by Spielpassung to the interference fit hole enlargement, and play the guide-localization effect, be difficult for dislocation when guaranteeing riveted, guarantee that the play of ball pocket is constant; The top of nail body is fastening a section 6 of interference, the rivet hole interference fit of itself and retainer.As shown in Figure 3, interior and the rivet hole interference fit of rivet hole of a retainer 1 is tightly inserted in the interference of rivet for fastening section 6, the rivet hole of following sheet retainer 3 and rivet second gradually extension diameter section 7 and changeover portion 8 combine, assembling back lab retainer is a drive fit with rivet also, constitutes the tacked constructions that carries of retainer.As shown in Figure 1, retainer is after packing rivet into, and the lower end cylinder of rivet is pressed into head of a nail shape by pier.
