Description
Technical field
The utility model belongs to bearing mounting technology field, especially a kind of auxiliary device that is used for the miniature bearing assembling.
Background technique
For miniature bearing, because the internal diameter of inner ring is not more than 10 millimeters, and the diameter of spin is generally below 1.588mm, and minimum spin is merely about 0.3mm, and spin weight is lighter.Especially ceramic ball, weight is merely about 40% of comparable size spin weight.
Because the spin that miniature bearing uses or the volume of ceramic ball is little, light weight, so assemble up extremely difficultly, the air-flow that the assembly crewman breathes out just can blow away ceramic ball, therefore, very easily loses spin during assembling.
Summary of the invention
In order to address the above problem; The utility model has designed a kind of auxiliary device that is used for the miniature bearing assembling; Adopt this auxiliary device can avoid the use of vaseline, do not lose spin in the assembly process, the spin easy fixation is in retainer pocket hole; It is simple in structure, easy to make that auxiliary device has, and can improve the efficiency of assembling of miniature bearing.
For realizing the foregoing invention purpose, the utility model adopts following technological scheme:
A kind of auxiliary device that is used for the miniature bearing assembling; Miniature bearing comprises outer ring, inner ring, retainer and spin; Wherein the external diameter of the internal diameter of outer ring, inner ring, retainer height, ball radius are all given; This auxiliary device is made up of support ring and receipts ball, and the positioning ring of wherein receiving on the ball is connected in ring seat top, and support ring is socketed in the positioning ring of receiving ball.
Above-mentioned support ring is spill; The bottom of support ring has endoporus; The diameter of said endoporus is less than the external diameter of inner ring, the outside diameter d c of support ring and the internal diameter coupling of receiving positioning ring on the ball, the height overall H1 of support ring with receive ball on the interior ring height of positioning ring equate; The interior ring of the thickness of said endoporus=height overall H1-support ring is high, high half the in the retainer height of the interior ring of support ring.
The height overall H1+ ball radius of the high H=support ring of outer shroud of positioning ring on the above-mentioned receipts ball; Receive the internal diameter of the outer shroud external diameter >=outer ring of positioning ring on the ball; The high height overall H1 with support ring of interior ring that receives positioning ring on the ball is complementary; The ring seat top of receiving on the ball has the concavity oil trap, and the inner diameter d n of this oil trap is less than the external diameter of inner ring but greater than the diameter of said endoporus.
Owing to adopted technique scheme, the utility model to produce following beneficial effect:
1, receiving ball and support ring should confirm according to the miniature bearing physical dimension of being assembled, and the miniature bearing of different model should supportingly design corresponding receipts ball and support ring, and receipts ball and support ring have simple in structure, easy to make, the characteristics of assembling practicality.
2, use the utility model can avoid using in the assembly process vaseline; Guaranteed that miniature bearing is inner clean; Reduced the phenomenon of losing of spin in the assembly process, soak into the lubricating oil retainer and can adsorb spin, and can play self-lubricating function; Can improve the efficiency of assembling of same model miniature bearing greatly, save assembly crewman's work energy.

Embodiment
The utility model is a kind of auxiliary device that is used for the miniature bearing assembling, and miniature bearing comprises outer ring, inner ring, retainer and spin, and wherein the external diameter of the internal diameter of outer ring, inner ring, retainer height, ball radius are all given.
The auxiliary device of the utility model is made up of support ring 1 and receipts ball 2, and the positioning ring of wherein receiving on the ball 2 2.2 is connected in ring seat 2.1 tops, and support ring 1 is socketed in the positioning ring 2.2 of receiving ball 2.
The support ring 1 of the utility model is spill; The bottom of support ring 1 has endoporus; The diameter of said endoporus is less than the external diameter of inner ring, the outside diameter d c of support ring 1 and the internal diameter coupling of receiving positioning ring 2.2 on the ball 2, the height overall H1 of support ring 1 with receive ball 2 on the interior ring height of positioning ring 2.2 equate; The interior ring of the thickness of said endoporus=height overall H1-support ring 1 is high, high half the in the retainer height of the interior ring of support ring 1.
The height overall H1+ ball radius of the high H=support ring of outer shroud of positioning ring 2.2 on the above-mentioned receipts ball 2; Receive the internal diameter of the outer shroud external diameter >=outer ring of positioning ring 2.2 on the ball 2; The high height overall H1 with support ring 1 of interior ring that receives positioning ring 2.2 on the ball 2 is complementary; Ring seat 2.1 tops of receiving on the ball 2 have the concavity oil trap, and the inner diameter d n of this oil trap is less than the external diameter of inner ring but greater than the diameter of said endoporus.
When using the utility model; The retainer that is soaked with lubricant oil is placed in the support ring 1; The inner ring of on retainer, packing into then; Because the external diameter of inner ring is greater than the diameter of said endoporus; Therefore inner ring can not fall into said endoporus, high intilted annular slope, the high assembling supporting surface that constitutes spin of the outer shroud of this annular slope and support ring 1 of forming of the high and interior ring of outer shroud of receiving positioning ring 2.2 on the ball 2; To be provided with that quantity equates and the spin that is soaked with lubricant oil is put on the said assembling supporting surface with retainer pocket hole; Said assembling supporting surface can guarantee that spin presses close to retainer and can not lose, stir one of them spin gently and this spin got in one of them pocket hole of retainer with little spoon to get in retainer pocket holes until all spin, an end that then outer ring is had an inclined-plane aim at retainer and push downwards with receive ball 2 on the outer shroud height of positioning ring 2.2 contact fully; To be unkitted the micro rolling ball bearing for preparing then and receive ball 2 and support ring 1, and continue to push the outer ring and make itself and inner ring keeping parallelism promptly accomplish the assembly process of miniature bearing together with receiving to remove again after ball 2 together turns with support ring 1.
