Abstract
The utility model discloses a kind of bearing fixing device, is made up of the upper card key of body, a lower card key and two；Wherein, body is bearing, lower card key, the supporting mass of upper card key, for installing the shell of bearing, internal diameter size is identical with bearing outer ring outside dimension, the annular groove of card key and upper card key under installation is machined with the middle part of the inner surface of body 1, lower card key and upper card key are split to form by a complete circle, and thickness is identical with the width of body annular groove.The utility model proposes bearing outer ring fixing device, contrast prior art, be easy to process bearing case mounting hole, ensure cylindricity and coaxial bearing degree, and improve bearing and bear axial load requirement.
Description
Technical field
The utility model belongs to mechanical engineering technical field, is related to one kind and holds fixing device.
Background technology
Existing bearing fixed form generally use China Machine Press《Mechanical design handbook》The P20-98 of volume 3 is related to
Structure, as the axial restraint mode of bearing outer ring can take end cap fastening, circlip fastening, locating snap ring fastening, shoulder block it is tight
Gu etc. mode, but above fixed form is respectively present that space-consuming is big, bearing capacity is small, not easy processing the defects of.
Utility model content
The purpose of this utility model is to provide a kind of bearing fixing device, overcomes bearing capacity in existing bearing fastening means
It is small, not easy processing the defects of.
The technical solution of the utility model is：A kind of bearing fixing device, it is characterised in that：By 1, lower card key of body
2 and two upper card keys 3 form；Wherein, the internal diameter size of body 1 is identical with bearing outer ring outside dimension, in the inner surface of body 1
Middle part is machined with the annular groove of the lower card key 2 of installation and upper card key 3.
Beneficial effect：The utility model proposes bearing outer ring fixing device, contrast prior art, be easy to process bearing outside
Shell mounting hole, ensure cylindricity and coaxial bearing degree, and improve bearing and bear axial load requirement.
Brief description of the drawings
Fig. 1 is the card key figure of the utility model embodiment；
Fig. 2 is the installation diagram of the utility model embodiment.
Embodiment
To make the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
It is described in further detail.
The utility model provides a kind of bearing fixing device, is made up of 1, lower card key 2 of body and two upper card keys 3；
Wherein, body 1 is bearing, lower card key, the supporting mass of upper card key, for installing the shell of bearing, internal diameter size and bearing outer ring
Outside dimension is identical, and the annular groove of card key 2 and upper card key 3 under installation, the lower He of card key 2 are machined with the middle part of the inner surface of body 1
Upper card key 3 is split to form by a complete circle, and thickness is identical with the width of the annular groove of body 1.
The implementation process of the present apparatus：1. processing inner cylinder face on body 1, diameter is identical with bearing outside diameter；2. process ring
Shape groove diameter is identical with card key external diameter, and annular groove width is identical with card key thickness；3. card key 2 and upper card under being installed in annular groove
Key 3；4. installing taper roll bearing using back-to-back mode, paste both ends of the surface of the back side of bearing outer ring respectively with card key
Close, bearing outer ring external diameter is interference fitted with body, and rotating shaft is arranged in bearing.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as the scope of protection of the utility model.
