The content of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of spherical bearing, by directly will
The inner ring of spherical bearing block is processed into spherical outside surface, spherical bearing steel disk function is directly realized by spherical bearing block so that ball
Spherical bearing is reduced to two parts by three original parts, saves cost, reduces rigging error, improves precision；Together
When, oil groove is opened in the Internal Spherical Surface of spherical bearing block, without processing oil groove in spherical bearing copper dish, reduces and is processed into
This.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
A kind of spherical bearing, including spherical bearing block and spherical bearing copper dish, the spherical bearing block have Internal Spherical Surface, ball
Spherical bearing copper dish have spherical outside surface, and the spherical outside surface and Internal Spherical Surface match；It is equal along its axis in the Internal Spherical Surface of spherical bearing block
It is even that some spherical rollers are distributed with, along its axis it is evenly distributed with some oil grooves, spherical axis in the Internal Spherical Surface of spherical bearing block
The Internal Spherical Surface of bearing is provided with some arc grooves, and the arc groove and oil groove intersect and insertion.By directly by spherical bearing block
Inner ring be processed into spherical outside surface, spherical bearing steel disk function is directly realized by spherical bearing block so that spherical bearing is by original
Three parts come are reduced to two parts, save cost, reduce rigging error, improve precision；Meanwhile, oil groove is opened
It is located in the Internal Spherical Surface of spherical bearing block, without processing oil groove in spherical bearing copper dish, reduces processing cost.
Preferably, the oil groove is in circular arc, oil groove is arranged at intervals successively with arc groove, and adjacent oil groove and circular arc
Intersect insertion between groove, all oil grooves cross with arc groove in spherical bearing block in the center of Internal Spherical Surface.
Preferably, the quantity of the oil groove is eight, the quantity of arc groove is eight.
Preferably, the Internal Spherical Surface of the oil groove and spherical bearing block is by arc transition, the arc groove and spherical axis
The Internal Spherical Surface of bearing passes through arc transition.
The spherical bearing block is steel.By original copper spherical bearing copper dish and original spherical bearing block one into
Type is made, and material uses steel, and its service life is greatly increased.
Compared with prior art, the beneficial effects of the invention are as follows：The inner ring of spherical bearing block is processed into by directly outer
Sphere, spherical bearing steel disk function is directly realized by spherical bearing block so that spherical bearing is subtracted by three original parts
It is less two parts, saves cost, reduce rigging error, improve precision；Meanwhile, oil groove is opened in spherical bearing block
Internal Spherical Surface on, without processing oil groove in spherical bearing copper dish, reduce processing cost.

Embodiment
Embodiment of the present utility model is made a detailed explanation below in conjunction with the accompanying drawings.
A kind of spherical bearing as shown in Figure 1 to 4, including spherical bearing block 1 and spherical bearing copper dish 2, spherical bearing
Seat 1 is steel.The spherical bearing block 1 has Internal Spherical Surface 11, and spherical bearing copper dish 2 have spherical outside surface 21, the spherical outside surface 21
Match with Internal Spherical Surface 11.In the Internal Spherical Surface 11 of spherical bearing block 1 some spherical rollers 13 are evenly distributed with along its axis so that
Friction between spherical bearing block 1 and spherical bearing copper dish 2 is changed into rolling friction, reduces abrasion between the two, increasing it makes
Use the life-span.Along its axis be evenly distributed with some oil grooves 14 in the Internal Spherical Surface 11 of spherical bearing block 1, spherical bearing block 1 it is interior
Sphere 11 is provided with some arc grooves 15.Oil groove 14 is in circular arc, and oil groove 14 is arranged at intervals successively with arc groove 15, and adjacent
Intersect insertion between oil groove 14 and arc groove 15, all oil groove 14 is with arc groove 15 in spherical bearing block 1 in Internal Spherical Surface 11
Center crosses.
Oil groove 14 in the present embodiment is arranged on the axial direction of the Internal Spherical Surface 11 of spherical bearing block 1 consequently facilitating it adds
Work, passes through the setting of arc groove 15 and oil groove 14 so that spherical bearing, can be between Internal Spherical Surface 11 and spherical outside surface 21 when rotating
Uniform oil film is formed, the shock absorption and cooling effect of this oil film are more preferable.Pass through lubrication between Internal Spherical Surface 11 and spherical outside surface 21
Oil cooling but, reduces the adhesive wear caused by the deficiency that radiates；, also can be by because of abrasion by the setting of oil groove 14 and arc groove 15
