Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation
Book text can be implemented accordingly.
As shown in Figure 1-3, the utility model provides a kind of automobile bearing block, comprising: bearing block ontology, the bearing
Seat body bottom portion is mounting portion 1, and mounting portion 1 is connect with external agency, and the middle section of the bearing block ontology is fixed part, institute
The side for stating fixed part is equipped with body openings portion 10, is variant part 3, the body openings portion 10 above the body openings portion 10
Lower section is preload portion 11；
Bearing 2 is installed, one end of the bearing 2 is equipped with opening, and the opening is in body openings portion in the fixed part
10 sides, the opening of bearing 2 has a flexible deformation, and then elastic force is passed to bearing block ontology, and bearing block ontology is in bullet
Property power under the action of, portion 3 can be deformed in the top of opening portion 10, transmission shaft 12 is packed into bearing 2, because bearing 2 is opened
Mouth has a flexible deformation, so the internal diameter of bearing 2 will increase, the increase of internal diameter can be more convenient the loading of transmission shaft 12, simultaneously
The influence because of 12 machining tolerance of transmission shaft can also be overcome, and transmission shaft 12 is caused to assemble inconvenient problem；
The side of the variant part 3 is equipped with through-hole 9, is equipped with fastening screw 6 in the through-hole 9, and the fastening screw 6 is from upper
Through-hole 9 is passed through to lower, is equipped with the first ball pad 7 and the second ball pad 8 between the head of screw and through-hole 9 of the fastening screw 6, described the
The contact surface of one ball pad 7 and the second ball pad 8 is the spherical surface of cooperation, and first ball pad 7 and the contact surface of fastening screw 6 are flat
The contact surface of face, second ball pad 8 and variant part 3 is plane, during the connection process, because the reason of variant part 3, through-hole 9
Axis it is not parallel with the threaded hole in preload portion 11, so fastening screw 6 is during tightening, axis is to become always
Change, in practical work, the fastening screw 6 after fastening is often curved, causes dismounting fastening screw 6 all highly difficult, after giving
Continuous work causes no small trouble, passes through the first ball pad 7 of setting and the second ball pad 8, the contact of the first ball pad 7 and the second ball pad 8
Face is the spherical surface of cooperation, can effectively solve the problems, such as that fastening screw 6 bent, during the fastening process, axis is fastening screw 6
Change always, the cooperation spherical surface of the first ball pad 7 and the second ball pad 8 can the variation of adaptive fastening screw 6 always axis, no
Will lead to fastening screw 6 bent, and easy disassembly will not impact subsequent work, the fastening screw 6 and preload portion 11
By the threaded connection in preload portion 11, variant part 3 and preload portion 11 can be integrally connected by fastening screw 6, press variant part 3
Mandrel holds 2, and then compresses transmission shaft 12.
Specific work process are as follows: transmission shaft 12 is packed into the bearing 2 in fixed part, the head of screw of the fastening screw 6
The first ball pad 7 and the second ball pad 8 are equipped between through-hole 9, the contact surface of first ball pad 7 and the second ball pad 8 is to cooperate
Spherical surface, first ball pad 7 and the contact surface of fastening screw 6 are plane, and second ball pad 8 and the contact surface of variant part 3 are
Plane, during the connection process, because the axis of through-hole 9 is not parallel with the threaded hole in preload portion 11 the reason of variant part 3,
So fastening screw 6 is during tightening, axis changes always, and the contact surface of the first ball pad 7 and the second ball pad 8 is
The spherical surface of cooperation can effectively solve the problems, such as that fastening screw 6 bent, and during the fastening process, axis is always to fastening screw 6
Variation, the cooperation spherical surface of the first ball pad 7 and the second ball pad 8 can the variation of adaptive fastening screw 6 always axis, will not lead
Fastening screw 6 is caused to bent, variant part 3 and preload portion 11 are integrally connected by easy disassembly, fastening screw 6, make 3 compression axis of variant part
2 are held, and then compresses transmission shaft 12, can solve the influence because of 12 machining tolerance of transmission shaft, and leads to the assembly of transmission shaft 12 not side
Just the problem of.
The through-hole 9 is strip, and during the fastening process, axis changes always fastening screw 6, and strip leads to
Hole 9 can provide the space of variation for fastening screw 6, avoid fastening screw 6 and the inside of through-hole 9 from colliding with, influence to fasten
Effect；The top center position of the variant part 3 is equipped with oil filler point 4, is equipped with solenoid valve 5 at the oil filler point 4, passes through setting
Solenoid valve 5 and oil filler point 4 can automatically control in external lubricating oil injection bearing 2, extend the service life of bearing 2, together
When also mitigate the labor intensity of artificial addition lubricating oil；
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization.It can be applied to various fields suitable for the present invention completely.For those skilled in the art,
Other modifications may be easily implemented.Therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
