Description
Technical field
The present invention relates to bearings to assemble field, and in particular to a kind of assembly method of deep groove ball bearing secondary series rolling element.
Background technique
Miniature bearing, inner ring internal diameter is smaller, is usually no more than 10mm, and ball size is less than 1.622mm, and weight compared with
Gently, automatic assembling is relatively difficult to achieve.The assembly of usual single-row miniature deep groove ball bearing rolling element has special assembling die, miniature
The assembly of biserial deep groove ball bearing first row rolling element usually can apply above-mentioned assembling die, but assemble in secondary series rolling element
When, due to the presence of first row rolling element and first row retainer, secondary series rolling element is made to be difficult to connect with above-mentioned assembling die
Touching, therefore the assembly of secondary series rolling element is not available above-mentioned assembling die.The assembly of secondary series rolling element at present is by outer ring
It puts on the table, outer ring axis (i.e. in the horizontal direction) parallel with table surface, outer ring outer ring surface are contacted with workbench, hand
Work tweezers put rolling element on outer ring raceway, then the second inner ring is placed in the top of rolling element in outer ring, due to rolling element
Quality and small volume, tweezers press from both sides ball, and rolling element is easily fallen, and the rolling element set when placement inner ring easily skids off channel, fills
Ball process is extremely time-consuming, inefficiency, and the rolling element to set when preventing and placing inner ring skids off channel, can use the side of immersion oil
Formula increases rolling element surface viscosity, is sticked to rolling element in raceway, but the effect is unsatisfactory, and also needs after assembling to axis
It holds inside to be cleaned, increases cleaning difficulty.
Summary of the invention
The object of the present invention is to provide a kind of assembly method of deep groove ball bearing secondary series rolling element, this method operation letters
It is single, it is easy to get started, it can be improved working efficiency.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of deep groove ball bearing secondary series rolling
The assembly method of body, comprising the following steps:
Step 1: the bearing for assembling first row rolling element and first row retainer is fixed on the table, make outer ring
Axial one end vertical with table surface, outer ring secondary series rolling element to be assembled is upward；
Step 2: the second inner ring is put into outer ring, outer ring central axes are deviateed (i.e. in the second inner ring in the second inner ring central axes
Axis is not overlapped with outer ring central axes) make between the second inner ring outer ring surface and outer ring inner ring face side at a distance of relatively close, other side phase
Away from farther out, wherein side maximum distance apart from each other is greater than the diameter of secondary series rolling element, so that secondary series rolling element can
It is loaded into；
Step 3: side apart from each other between the second inner ring outer ring surface and outer ring inner ring face is put into one in semicircular ring
The gasket of shape, the internal diameter of the gasket are greater than the second inner ring outer diameter, and the outer diameter of gasket is less than outer ring internal diameter, and one end of gasket connects
There is the handle for moving the gasket (including being put into, taking out)；
Step 4: secondary series rolling element required for bearing is all placed on gasket, by being pre-designed spacer thickness
Keep secondary series rolling element corresponding for the position of raceway of assembling secondary series rolling element in outer ring, mobile second inner ring makes the
(secondary series rolling element is clamped in corresponding raceway by the second inner ring and outer ring at this time to the coincidence of outer ring central axes for two inner ring central axes
It is interior), locating shaft is inserted into the axis hole of the second inner ring and the first inner ring so that the relative position of the second inner ring and outer ring is fixed；
Step 5: take out gasket, stirring secondary series rolling element makes secondary series rolling element be evenly distributed on the second inner ring and outer
Between circle, it is then inserted into secondary series retainer between the second inner ring and outer ring, that is, completes miniature biserial deep groove ball bearing second
The assembly of column rolling element.
Further, in step 1, the upper surface of the workbench is equipped with equal with outer ring outer diameter for fixing outer ring
Columnar groove on the table, depth of groove are less than the height of outer ring；Further, the depth of groove is that outer ring is high
The half of degree.
Further, in step 2, the second inner ring outer ring surface is with outer ring inner ring face at a distance of closer side phase inscribe.
Further, in step 4, the sum of spacer thickness and secondary series rolling element radius are equal to first row retainer upper end
The distance of sagittal plane where raceway center in face to outer ring for assembling secondary series rolling element.
Further, handle is vertical with gasket upper surface.
Further, handle and gasket integrally connected.
The utility model has the advantages that operation of the present invention is simple, and it is easy to get started, working efficiency can be significantly improved；Assembly method of the present invention without
It need to be by rolling element immersion oil, it is ensured that biserial miniature bearing assembles the cleaning inside rear bearing, reduces the slight of bearing cleaning work；This
In inventive step one, outer ring is axially vertical with table surface, to be assembled to face upward, axial parallel with table surface with outer ring
It compares, rolling element is packed into from top to bottom, and it is low to the clamping device size requirement of rolling element, it is able to use larger (the opposite tweezer of size
For son) tool carry out dress ball, convenient for the clamping and assembly of rolling element.
