Abstract
The utility model discloses a kind of double ditch high-precision emery wheels, belong to idler wheel field, a kind of double ditch high-precision emery wheels include first groove, second groove, idler wheel matrix, boss；The upper end of the idler wheel matrix is disposed with first groove, boss, second groove, and the boss is located at the centre position of idler wheel matrix upper end, and the first groove, second groove are symmetrical about the boss.A kind of double ditch high-precision emery wheels disclosed by the utility model, by the way that double grooves are arranged so that double ditches of bearing can disposably be completed to process, and improve production efficiency, ensure that the relative positional accuracy of double ditches.
Description
Technical field
The utility model patent is related to idler wheel field, more particularly to a kind of double ditch high-precision emery wheels.
Background technology
Tiltable between the inside and outside circle of double-row angular contact bal bearing is limited, and inclination angle is allowed to depend on the inside of bearing
Gap, bearing size, interior design and power and torque on bearing are acted on, and maximum allowable inclination angle should ensure that in bearing not
It will produce excessively high additional stress.If there are inclinations angle between the inside and outside circle of bearing, the service life of bearing will be influenced, while causing axis
Acknowledgement of consignment turns accuracy decline, and running noise increases.Double-row angular contact bal bearing generally uses nylon cages or brass entity to keep
Frame.Although double-row angular contact bal bearing should be noted that bearing can bear bi-directional axial load when installing, if there is filling slot in side
When, then it should be noted that not allow predominantly axially load pass through side limes marginis jaggy.Bearing using when should be noted that and make without dress
The side raceway of segment mouth bears Main Load.
The twice ditch of traditional double-row angular contact bal bearing is processed respectively.
But inspection shaft in the prior art, there is apparent defect, machining accuracy is difficult to ensure double ditches respectively, simultaneously
Separate machined can cause processing technology complicated, low production efficiency.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of double ditch high-precision emery wheels, with solution
The problem of machining accuracy is difficult to ensure certainly double ditches respectively, while separate machined can cause processing technology complicated, low production efficiency.
The technical solution adopted in the utility model is：A kind of double ditch high-precision emery wheels, including first groove, are provided
Two grooves, idler wheel matrix, boss；The upper end of the idler wheel matrix is disposed with first groove, boss, second groove, described
Boss is located at the centre position of idler wheel matrix upper end, and the first groove, second groove are symmetrical about the boss.First
Groove, second groove are two boss shapes for processing grinding wheel, then pass through the boss sharp processing of the grinding wheel of processing
Bearing can largely improve production efficiency, while only need to ensure that the size of emery wheel ensures that processing
Bearing out is qualified, when abrasion of grinding wheel, can process new grinding wheel quickly, shorten die manufacturing cycle.
As being further improved for this programme, the size of the first groove is set according to the groove dimensions of actual processing bearing
It sets, the size of the second groove is identical as the first groove size.
Compared with prior art, the advantageous effect of the utility model patent is：
1, a kind of double ditch high-precision emery wheels provided by the utility model, by the way that double grooves are arranged so that pair of bearing
Ditch can disposably be completed to process, and improve production efficiency, ensure that the relative positional accuracy of double ditches.
Description of the drawings
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
The detailed description of one step, wherein：
Fig. 1 is the overall structure diagram of the utility model patent.
It is attached：The label of each component is as follows in figure：1- first grooves, 2- second grooves, 3- idler wheels matrix, 4- boss.
Specific implementation mode
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art and technical solution are briefly described, it should be apparent that, in being described below
Attached drawing be only some embodiments of the utility model, for those of ordinary skill in the art, do not paying creativeness
Under the premise of labour, other attached drawings are can also be obtained according to these attached drawings.
1 pair of the utility model further illustrates below in conjunction with the accompanying drawings.A kind of double ditch high-precision gold described in the utility model
Rigid idler wheel, including first groove 1, second groove 2, idler wheel matrix 3, boss 4；The upper end of the idler wheel matrix 3 is disposed with
First groove 1, boss 4, second groove 2, the boss 4 are located at the centre position of 3 upper end of idler wheel matrix, first ditch
Slot 1, second groove 2 are symmetrical about the boss 4.First groove 1, second groove 2 are two boss for processing grinding wheel
Shape can largely improve production efficiency, while only then by the boss sharp processing bearing of the grinding wheel of processing
It needs to ensure that the size of emery wheel ensures that the bearing processed is qualified, when abrasion of grinding wheel, can process quickly
Go out new grinding wheel, shortens die manufacturing cycle.
In this example, the size of the first groove 1 is arranged according to the groove dimensions of actual processing bearing, and described second
The size of groove 2 is identical as 1 size of the first groove.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any change or replacement expected without creative work should be covered within the scope of the utility model.
Therefore, the scope of protection of the utility model should be determined by the scope of protection defined in the claims.
