Groove；And, the fitting projection that cooperation is inlayed with the deep-slotted chip breaker that the reinforcing annular part has.
Optionally, the fitting projection is is arranged on the reinforcing annular part, the surface in face of the bearing block side
The upper arc convex structure being suitable in embedded above-mentioned deep-slotted chip breaker.
Optionally, at least circumferential side side wall of the mosaic texture tilts shaping for relatively described bearing block side,
So that reinforcing annular part insertion in telescopiny is deeper, and the combination of the bearing block is tighter；The reinforcing annular part
Keep close by attachment structure between the bearing block to be fitting to connection.
Optionally, the attachment structure includes being molded over first pedestal, second pedestal and the reinforcing annular
The connecting hole of part correspondence position, and, it is arranged in the threaded connector of the connecting hole.
Optionally, after first pedestal and second pedestal are fastened, respective deep-slotted chip breaker constitutes an annular groove；Phase
The fitting projection on Ying Di, the reinforcing annular part is annular protrusion.
Optionally, several connecting holes on first pedestal and second pedestal centered on axis hole axle center etc.
Angle is arranged.
Optionally, the reinforcing annular part is arranged on the bearing that first pedestal and second pedestal are constituted
The two sides of seat.
Optionally, the reinforcing annular part is structure as a whole in side with first pedestal and/or second pedestal.
Invention also provides a kind of jaw crusher, including the bearing block structure described in any of the above-described.
Technical solution of the present invention, has the following advantages that：
A kind of bearing block structure that the present invention is provided, due to the setting of annular structural part, has shared the first pedestal and second
The stress of threaded connector between pedestal, extends the service life of threaded connector, improves safety and reliability.

Embodiment
Technical scheme is clearly and completely described below in conjunction with accompanying drawing, it is clear that described implementation
Example is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Fig. 1 shows a kind of jaw crusher embodiment that the present invention is provided.
The jaw crusher includes frame, quiet jaw component, dynamic jaw component and drive component.Wherein, quiet jaw component has quiet
The jaw plane of disruption, is fixedly connected with frame.Dynamic jaw component has the dynamic jaw plane of disruption, is installed on frame.The dynamic jaw plane of disruption is broken with quiet jaw
It is in up big and down small crusher chamber to be formed between broken face, and charging aperture and discharge gate are respectively arranged with crusher chamber head and the tail two ends.Driving
Component includes the driving bent axle being connected with dynamic jaw component.Driving bent axle is installed in frame by bearing block.Power set pass through
The dynamic relatively quiet jaw component of jaw component of driving bent axle driving is moved back and forth in close, remote mode, and imitation animal two jaw is realized broken
Material in broken crusher chamber.
Due to, it is necessary to crushing force is larger, larger effect is finally generated to bearing block in the jaw crusher course of work
Power, is easily damaged and damages, and a kind of bearing block structure is provided for this technical program.
The bearing block structure includes the first pedestal 6, the second pedestal 5 and is arranged on the first pedestal 6 and the both sides of the second pedestal 5
Reinforcing annular part 3.Wherein, the first pedestal 6 is fixedly mounted in frame.First pedestal 6 can be Split type structure with frame, pass through
Bolt, welding etc. are well known to those skilled in the art to be detachably connected the detachable installation that mode realizes the first pedestal and frame.
First pedestal can also set with frame and be structure as a whole.
First pedestal 6 and the second pedestal 5 are respectively the half of circular configuration substantially.Second pedestal 5 is installed on by bolt
One pedestal.First pedestal and the formation of the fasten and coordinate of the second pedestal 5 are with the axis hole passed through for installation axle 1.Installation axle 1 and axis hole
Between bearing 2 is installed.In the present embodiment, installation axle 1 is the driving bent axle of jaw crusher.
First pedestal 6 and the side of the second pedestal 5 are provided with the deep-slotted chip breaker using axis hole axis as the center of circle.Reinforcing annular part 3
Bearing block side is arranged on, the centre bore set with correspondence axis hole.Reinforcing annular part 3 also has the table in face of bearing block side
It is suitable to the fitting projection in embedded above-mentioned deep-slotted chip breaker on face.Fitting projection is arc convex structure corresponding with arc groove shape.
Reinforcing annular part 3 is realized by the cooperation of fitting projection and deep-slotted chip breaker with the first pedestal 6 and the second pedestal 5 be fixedly linked respectively.
Deep-slotted chip breaker and fitting projection at least circumferential side side wall are that relative bearing block side tilts shaping, and both pass through even
The connection of binding structure keeps close and is fitting to connection.Attachment structure includes the first pedestal 6, the second pedestal 5 and the corresponding position of reinforcing annular part 3
The connecting hole 7 put, and, it is arranged in the screw of connecting hole 7.It is designed so that reinforcing annular part 3 is embedding in telescopiny
Enter deeper, and the combination of bearing block is tighter, while can avoid because the bearing block produced by machining accuracy problem installs insecure
The problem of.
Attachment structure is provided with multiple.Multiple attachment structures are on the first pedestal 6 and the second pedestal 5 using axis hole axle center in
The heart is equiangularly arranged.
After first pedestal 6 and the second pedestal 5 are fastened, respective deep-slotted chip breaker constitutes an annular groove.Correspondingly, reinforcing annular
Fitting projection on part 3 is annular protrusion.
Because reinforcing annular part 3 with the first pedestal 6 and the second pedestal 5 by being fixedly connected respectively, share to existing
The active force of the bolt of the first pedestal 6 and the second pedestal 5 is connected in technology, security is improved, and reduce the possibility of damage
Property.
As another embodiment, reinforcing annular part 3 is integrated knot in side and the first pedestal 6 and/or the second pedestal 5
Structure.
It should be evident that deep-slotted chip breaker and/or fitting projection can be smaller for point-like, the structure of section shape, i.e. development length, i.e., not
It is confined to the groove and/or projection of circular shape.Can be deep-slotted chip breaker and the cooperation of multiple columnar projections.Deep-slotted chip breaker and cooperation are convex
Rise and synthesize mosaic texture 4.
It should be evident that reinforcing annular part 3 such as can directly be connected through a screw thread, weld at the company well known to those skilled in the art
The mode of connecing realizes the connection between the first pedestal and the second pedestal 5.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
