Abstract
The utility model discloses a kind of bearing cages with mortise-tenon joint structure, including retainer ontology, retainer ontology is inc circular ring shape, several evenly spaced pocket holes are provided on the periphery of retainer ontology, the left side of retainer ontology is provided with mortise, the right side of retainer ontology is provided with tenon corresponding with the mortise, and tenon is fitted in mortise, and there are the adjusting gaps that width is h between the left side of tenon and the left side of mortise.Retainer ontology uses inc cirque structure, it is equipped by the mortise of the tenon of one end and the other end again, and there are certain gaps between tenon and mortise, so that retainer ontology had both had the adjustable effect of diameter, it ensure that the flexibility of retainer ontology, and the steel ball in pocket hole is allow more uniformly to be distributed in bearing is rolled into again so that retainer ontology has certain limitation.
Description
Technical field
The utility model belongs to technical field of bearings, and in particular to a kind of bearing cage with mortise-tenon joint structure.
Background technology
Bearing is mainly used for determining the position of rotary shaft and other part relative motions, and it is whole that its quality directly affects machinery
The working performance of machine drives the movement of associated mechanisms by the operating of bearing.And steel ball plays rotation inside raceway and makees
With while, bearing function is also carry, to make bearing circumference stress equalization, so retainer is needed uniformly to be distributed steel ball
In Bearing inner.Existing retainer is welded into integral solder closed loop configuration retainer, has open loop type retainer, integral solder to close
Ring structure retainer size has been fixed, and can cause retainer and bearing wear when being mismatched with Bearing inner size, and generate
Noise.And open loop type retainer is too small to the constraint of steel ball, steel ball cannot be made to be uniformly distributed in raceway.
Invention content
In order to solve the above technical problems, the purpose of this utility model is to propose that a kind of bearing with mortise-tenon joint structure is protected
Holder.
In order to realize that above-mentioned purpose of utility model, the utility model use technical solution as described below：
A kind of bearing cage with mortise-tenon joint structure, including retainer ontology, retainer ontology are inc
Circular ring shape is provided with several evenly spaced pocket holes, the left side setting of retainer ontology on the periphery of retainer ontology
There are mortise, the right side of retainer ontology to be provided with tenon corresponding with the mortise, tenon is fitted in mortise, and tenon
There are the adjusting gaps that width is h between the left side and the left side of mortise of head.
Further, the tenon is in left wide right narrow dovetail shaped with mortise, and tenon right side and retainer ontology are left
End face is connected by changeover portion, and the width of changeover portion is h, and the height of changeover portion is identical as the height of tenon right side, mortise
Upper and lower side is made of flat face and inclined surface, and the width of flat face is h.
Further, the tenon, changeover portion and retainer ontology are integrally formed.
Further, the retainer ontology is molded by steel plate bending.
Due to the adoption of the above technical scheme, the utility model has following superiority：
Retainer ontology uses inc cirque structure, then equipped by the tenon of one end and the mortise of the other end,
And there are certain gaps between tenon and mortise so that retainer ontology had both had the adjustable effect of diameter, protected
The flexibility of retainer ontology has been demonstrate,proved, and the steel ball in pocket hole is allow more uniformly to be distributed in bearing is rolled into again,
So that retainer ontology has certain limitation.

In figure：1, retainer ontology；2, tenon；3, mortise；4, changeover portion；5, flat face；6, inclined surface；7, pocket hole.
Specific implementation mode
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figure 1, 2, 3, a kind of bearing cage with mortise-tenon joint structure, including retainer ontology 1, retainer
Ontology 1 is inc circular ring shape, and several evenly spaced pocket holes 7, retainer are provided on the periphery of retainer ontology 1
The left side of ontology 1 is provided with mortise 3, and the right side of retainer ontology 1 is provided with tenon 2 corresponding with the mortise 3, tenon
First 2 are fitted in mortise 3, and there are the adjusting gaps that width is h between the left side of tenon 2 and the left side of mortise 3.
The tenon 2 is in left wide right narrow dovetail shaped with mortise 3, and 2 right side of tenon and 1 left side of retainer ontology are logical
The connection of changeover portion 4 is crossed, the width of changeover portion 4 is h, and the height of changeover portion 4 is identical as the height of 2 right side of tenon, mortise 3
Upper and lower side is made of flat face 5 and inclined surface 6, and the width of flat face 5 is h.
The tenon 2, changeover portion 4 and retainer ontology 1 are integrally formed.
The retainer ontology 1 is molded by steel plate bending.
Retainer ontology uses inc cirque structure, then equipped by the tenon of one end and the mortise of the other end,
And there are certain gaps between tenon and mortise so that retainer ontology had both had the adjustable effect of diameter, protected
The flexibility of retainer ontology has been demonstrate,proved, and the steel ball in pocket hole is allow more uniformly to be distributed in bearing is rolled into again,
So that retainer ontology has certain limitation.
