Abstract
The utility model relates to the technical field of bearings, in particular to an integrated bearing. The integrated bearing comprises a bearing body and a central spindle. The bearing body is sleeved outside the central spindle. The bearing body comprises an outer ring, a retainer and rolling bodies. An outer ring rolling groove is disposed on the inner ring wall of the outer ring along the radial direction. An inner ring rolling groove is arranged in a position, corresponding to the outer ring rolling groove, of the outer wall of the central spindle along the radial direction of the central spindle. The inner ring rolling groove and the outer ring rolling groove form a roller path. The retainer is arranged between the outer ring and the central spindle. The rolling bodies are arranged in the roller path through the retainer in a moving mode. According to the integrated bearing, the inner ring rolling groove for assembling the rolling bodies is directly arranged on the central spindle, an inner ring is eliminated, and the assembling process of the inner ring and the central spindle is omitted. Consequently, influences caused by installation are effectively avoided, the machining accuracy of the bearing is maintained, noise and on-line reject ratio of the bearing are reduced, and the service life of the bearing is prolonged. Moreover, the integrated bearing saves selective assembly and installation of customers, reduces cost, and improves online qualified rate and production efficiency.
Description
Technical field
The utility model relates to technical field of bearings.
Background technique
Bearing (" Bearing ", Japan's person " axle is subjected to ") is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.The structure of existing bearing is (such as Fig. 1) usually, comprises outer ring 2, inner ring 3 and is fixed on rolling element 4 between the Internal and external cycle 3,2 by retainer 5; For some bearings, belong to frivolous series product such as the bearing on the automobile vacuum pump, bearing uses when installing, mandrel is plugged in the bearing inner race by interference fit and is installed together, and inner ring is with after mandrel cooperates, and distortion appears in inner ring, make the original precision forfeiture of bearing, as causing the circularity of raceway to change, precision and noise after bearing is installed change, and cause after the installation higher and life-span of noise reject ratio not reach requirement; And this bearing is when installing, and the changed play of bearing is larger, needs the apolegamy of internal diameter and mandrel size in the installation process, causes the online up-to-standard rate after the lower and installation of installation efficiency low.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of integrated bearing, adopts mandrel and inner ring to adopt integrated setting, and the impact of avoiding the apolegamy of mandrel and inner ring to install has reduced the running noise of bearing, the life-span of improving bearing.
For achieving the above object, the utility model provides following technological scheme: a kind of integrated bearing, include bearing body and mandrel, described bearing body is enclosed within the mandrel outside, described bearing body includes the outer ring, retainer and rolling element, offer the outer ring slot rolling that is disposed radially on the internal ring wall of outer ring, it is characterized in that: the position of corresponding outer ring slot rolling is provided with the inner ring slot rolling that radially arranges along mandrel on the outer wall of described mandrel, described inner ring slot rolling and outer ring slot rolling consist of raceway, described retainer is located between outer ring and the mandrel, and rolling element is assigned in the raceway by retainer is moving.
By adopting technique scheme, the elimination bearing inner race arranges, directly offer the inner ring slot rolling at mandrel and be used for the assembling rolling element, omitted the link that cooperates in traditional bearing inner race and the mandrel assembly process, effectively avoided installing the impact that causes, the machining accuracy of bearing is maintained, has reduced noise and the online reject ratio of bearing, promote the life-span of bearing; And this structure saved client's apolegamy and installation, makes cost, improved online up-to-standard rate, improved manufacturing efficiency.
The utility model further is set to: be provided with the seal ring that is positioned at the raceway both sides between the fitting surface of described outer ring and mandrel, form the Seal cage of accommodating rolling element between the outer ring of the seal ring of both sides and the fitting surface of mandrel.
By adopting technique scheme, seal ring effectively stops external dust, moisture and other foreign matter to enter bearing inside, well protects bearing, improves bearing working life.
The utility model further is set to: the axial length of described mandrel and the axial length of outer ring are suitable, and mandrel is provided with the some mounting holes that arrange vertically.
By adopting technique scheme, the length of mandrel and outer ring is suitable, makes bearing structure compact, on the mandrel mounting hole is set simultaneously, reaches the purpose of fixed outer part.
Below in conjunction with accompanying drawing the utility model is further described.
