Abstract
The invention discloses a circular base spherical outside surface rolling bearing, comprising an outer ring (1), an inner ring (2), a roller (3) and a sealing ring (4); the outer ring (1) is sheathed on the inner ring (2), the roller (3) is arranged between the outer ring (1) and the inner ring (2), a gap between the outer ring (1) and the inner ring (2) is sealed by the sealing ring (4); wherein the inner side of the outer ring (1) is a bearing roller path, 20 threaded through holes are uniformly distributed on the outer ring (1), and 20 threaded through holes are uniformly distributed on the inner ring (1); the threaded through holes on the inner ring and the outer ring have fixing functions, the bearing can be fixed in the working occasions by the bolt, so as to greatly simplify the assembling process, improve the working condition and improve the bearing life.
Description
Technical field
The present invention relates to a kind of circular base spherical outside surface rolling bearing, belong to the spherical outside surface rolling bearing technical field of usheing to seat.
Background technique
Rolling bearing units are owing to have advantages such as compact structure, perfect, the easy to loading and unloading and self-aligning amplitude of sealing are bigger, make the frame of many main frames can adopt into the technology of structural section punching out or welding, have also improved the performance of machine.Its characteristics are: brearing bore adopts plus tolerance, with cooperating of axle be Spielpassung, and be close to the firmware transmitted power, the requirement on machining accuracy to axle is lower like this, mounting or dismounting simultaneously are also very convenient; This bearing supply in full sets of can usheing to seat along with the development of this bearing, the special manufacturer of bearing with spherical outside surface seat also occurred simultaneously, so adopt this bearing support design and processing, can shorten the cycle greatly, reduces cost.
Rolling bearing pedestal is one of important mechanical fitting, and some domestic in recent years producers have also successively introduced the manufacturing technology and the equipment of the rolling bearing of usheing to seat, and begin to put into production, have formed standardization and seriation at present.Rolling bearing units owing to have advantages such as compact structure, perfect, the easy to loading and unloading and self-aligning amplitude of sealing are bigger, make the frame of many main frames can adopt into the technology of structural section punching out or welding to call rolling bearing units in the following text, have also improved the performance of machine.But there are problems such as assembling difficulty.
Summary of the invention
The present invention provides a kind of circular base spherical outside surface rolling bearing for solving on the above technical problem, has solved problems such as assembling difficulty.
A kind of circular base spherical outside surface rolling bearing of the present invention comprises outer ring, inner ring, roller, seal ring, ball blocking block and taper pin; The external diameter of the described outer ring fillet of leaning now to one side, then to the other; One circular arc roller raceway is arranged on the endoporus of outer ring, a little arc groove is arranged in the roller raceway; A side of circular arc roller raceway has a rectangular recess on the endoporus of outer ring; The outer ring has equally distributed tapped through hole vertically; Tapped through hole on the described outer ring is 20; One circular arc roller raceway is arranged on the external diameter of described inner ring, a little arc groove is arranged in the roller raceway; A side of circular arc roller raceway has a rectangular recess on the external diameter of inner ring; The endoporus of the described inner ring fillet of leaning now to one side, then to the other; One oil guiding hole is arranged between the external diameter of described inner ring and the endoporus, and oil guiding hole has a blind bolt near the endoporus side of inner ring; Equally distributed vertically tapped through hole is arranged on the inner ring, and the tapped through hole on the described inner ring is 20.Side on the circumference of described outer ring is offered cell body at the middle part, in the described cell body ball blocking block is set; The axial direction that is positioned at parallel described outer ring, described cell body position on described outer ring is offered pin-and-hole; Offer the conical bore of corresponding described outer ring pin-and-hole on the described ball blocking block, in described pin-and-hole and conical bore, taper pin is set, thereby described ball blocking block is locked on the described outer ring; Described ball blocking block is provided with raceway near inner ring one side, and one section little arc groove is arranged on the raceway.
The present invention compared with prior art, tapped through hole on the inner ring and the tapped through hole on the outer ring play fixation, connect and can simplify assembly process greatly, improve operating conditions and improve bearing life with bearing fixing in the workplace by bolt.
