Description
Technical field
This utility model relates to mechanical field, particularly relates to a kind of four point touching ball slewing bearing.
Background technology
In use, general structure is fairly simple for existing device, to bearing top circle and bearing
Typically insert multiple ball between inner circle, increase between bearing top circle and bearing inner circle and ball
Friction, it has not been convenient to reduced between bearing top circle and bearing inner circle and ball by four rolling
Friction, increases contact area, wastes resource, add use cost, and be not easy
Being replaced, bring inconvenience for user, also device is in use, to different size
Bearing top circle the most convenient when being replaced, it has not been convenient to by support bar according to outside bearing
The size of circle is adjusted, and decreases the scope of application, have impact on the use of user, also has dress
Put in use, typically the rotating shaft of fixed dimension can only be fixed, it has not been convenient to by fixing
The rotating shaft of different thicknesses is fixed by plate, reduces range, brings user not
Just.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of 4 points
Contact ball slewing bearing.
This utility model is to be achieved through the following technical solutions:
A kind of four point touching ball slewing bearing, including bearing inner circle, symmetrical in described bearing inner circle
It is provided with support bar, is provided with fixed plate inside described support bar, outside described support bar, is provided with roller,
It is provided with trip bolt between described roller and support bar, outside described roller, is provided with bearing top circle,
It is uniformly provided with through hole on described bearing top circle.
As optimal technical scheme of the present utility model, described support bar is with round thread in bearing even
Connect.
As optimal technical scheme of the present utility model, described support bar is fixing with fixed plate to be connected.
As optimal technical scheme of the present utility model, described roller and support bar are by fastening spiral shell
Nail is articulated and connected.
As optimal technical scheme of the present utility model, described roller is slidably connected with bearing top circle.
Compared with prior art, the beneficial effects of the utility model are:
This utility model, by arranging support bar, is preferably adjusted according to the size of bearing top circle
Joint, facilitates different size of bearing to use, and conveniently carries out different size of bearing top circle
Change, saved resource, decreased use cost, added range, for user band
Carried out convenience, by arranging four rolling, preferably decrease bearing inner circle and bearing top circle with
The contact area of ball, the friction between decreasing, add the service life of bearing, save
Resource, decreases use cost, provides conveniently for user, by arranging fixed plate,
Preferably the rotating shaft to different thicknesses is fixed, and adds the scope of application, and simple in construction,
Reasonable in design, easy to operate, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, bearing inner circle, 2, fixed plate, 3, trip bolt, 4, support bar, 5,
Bearing top circle, 6, through hole, 7, roller.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment
Technical scheme be clearly and completely described, it is clear that described embodiment be only this
The a part of embodiment of utility model rather than whole embodiments.Based on this utility model
In embodiment, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of technical scheme of this utility model offer:
A kind of four point touching ball slewing bearing, including bearing inner circle 1, symmetrical in bearing inner circle 1
Being provided with support bar 4, support bar 4 is threadeded with bearing inner circle 1, is provided with inside support bar 4
Fixed plate 2, support bar 4 is fixing with fixed plate 2 to be connected, and is provided with roller 7 outside support bar 4,
Being provided with trip bolt 3 between roller 7 and support bar 4, roller 7 and support bar 4 are by fastening
Screw 3 is articulated and connected, and is provided with bearing top circle 5, roller 7 and bearing top circle 5 outside roller 7
It is slidably connected, bearing top circle 5 is uniformly provided with through hole 6.
During onsite application, device is suitably positioned, then by bearing top circle 5 by logical
Hole 6 is fixed to specify position, then rotates support bar 4, makes four rolling 7 and bearing top circle
5 carry out good contact, then rotating shaft are fixed by fixed plate 2, proceed by running,
When bearing top circle 5 is replaced by needs, it is only necessary to according to the size of bearing top circle 5 to
Strut 4 is adjusted, and can also be changed by regulation support bar 4 and turn different thicknesses
Axle is fixed, and uses convenient, and when the position of bearing top circle 5 places, regulation is tight
Gu screw 3, adjust the angles and positions of roller 7, make roller 7 good with bearing top circle 5
Contact, then rotating shaft starts band dynamic bearing and rotates.
Embodiment the most of the present utility model, common for this area
For technical staff, it is possible to understand that in the case of without departing from principle of the present utility model and spirit
These embodiments can be carried out multiple change, revise, replace and modification, of the present utility model
Scope is defined by the appended claims and the equivalents thereof.
