Description
Technical field
The present invention relates to a kind of bearing holder.
Background technology
In the retainer that (with diameter greater than 400mm) is used in existing large size bearing, including keep stand, retainer lid
And roller, roller is connected between holding stand and retainer lid, keeps stand, retainer lid and roller to use metal
Material is made, such as existing most use Copper alloy material is made.
This kind of retainer operationally, with the high-speed rotation of roller, was also easy to produce noise and height on retainer at that time
Warm deformation, influences the running precision of retainer, reduction of service life.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided a kind of bearing holder.
The technical solution adopted for the present invention to solve the technical problems is：A kind of bearing holder, including two axial directions are right
Claim the back-up ring for setting, several spacing blocks being made of self-lubricating material, each isolation are provided between two back-up ring
Block is fixedly installed between two back-up rings, and each spacing block constitutes cyclic structure between two back-up rings；On the single spacing block
At least one first slot rollings are offered, the first roller is respectively arranged with the first slot rolling of each spacing block；
There is gap between the end face of the two neighboring spacing block joint；
The gap forms the second slot rolling between two neighboring spacing block, the second rolling formed between each spacing block
The second roller is respectively arranged with groove.
Further, the both sides lower end of each spacing block is respectively arranged with rib, and two rib is fitted setting respectively
On the inner hole wall of both sides back-up ring.
Further, the both sides upper end of each spacing block is respectively arranged with rib, and two rib is fitted setting respectively
In the outside diameter wall of both sides back-up ring.
Further, the quantity of the first slot rolling is 1 or 2 or 3 or 4 or 5 on the spacing block.
Further, the material of the spacing block is PA66 or PA46 or PEEK.
Further, the spacing block is connected with two back-up rings through closing-up, and the rivet passes through back-up ring and spacing block
Afterwards with opposite back-up ring riveted.
The beneficial effects of the invention are as follows：It is arranged in the slot rolling of self-lubricating material by by roller, roller can be made when long
Between rotate after remain to make keep good greasy property between roller and spacing block, it is to avoid roller rotate sent on retainer
Noise.
Gap between adjacent spacing block, can improve the heat dispersion of whole retainer, it is to avoid retainer long-time work
Make and cause its high temperature deformation.
By the second slot rolling formed in gap, and the second roller set in the second slot rolling, this hair can be improved
The workload of bright retainer becomes big, and user can choose whether to need to install second in each second slot rolling as needed
Roller；When retainer is in semi-load pattern, the first roller can be only retained on retainer；When retainer is in full load pattern
When, the second roller can be installed in the second slot rolling again, the load capacity of retainer of the present invention is improved with this.
The setting of spacing block both sides rib, can meet the inner ring guiding or outer ring guiding of retainer, to meet retainer
Running precision and rise a guiding function.
The bonding strength between each spacing block and both sides back-up ring can be improved, it is to avoid because being arranged on the height of inner ring in retainer
Speed is rotated and isolation block assembly is deformed.

Specific embodiment
Presently in connection with specific embodiment, the present invention is further illustrated.These accompanying drawings be simplified schematic diagram only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant with the present invention.
As shown in Figure 1 to Figure 2, a kind of bearing holder, including two axially symmetric settings back-up ring 1, between two back-up rings 1
Several spacing blocks 2 being made of self-lubricating material are provided with, each spacing block 2 is fixedly installed between two back-up rings 1, and respectively
Spacing block 2 constitutes cyclic structure between two back-up rings 1；At least one first slot rollings 21 are offered on single spacing block 2, each isolation
The first roller 3 is respectively arranged with first slot rolling 21 of block 2, each spacing block 2 is formed through same mold injection；
The quantity of the first slot rolling 21 can be 1 or 2 or 3 or 4 or 5 on single spacing block 2, make
It is preferred, the present embodiment, the quantity of the first slot rolling 21 preferably one.
The material of spacing block 2 is PA66 or PA46 or PEEK plastics.
To improve the heat dispersion of retainer, there is gap between the end face of the joint of two neighboring spacing block 2.
In order to improve the load capacity of retainer, gap forms the second slot rolling 4 between two neighboring spacing block 2, respectively every
The second roller 5 is respectively arranged with the second slot rolling 4 formed between block 2.User can choose whether needs as needed
Second roller 5 is installed in each second slot rolling 4；When retainer is in semi-load pattern, as shown in figure 3, can be only on retainer
Retain the first roller 3；When retainer is in full load pattern, the second roller 5, the first rolling can be installed in the second slot rolling 4 again
The roller 5 of post 3 and second is used simultaneously, and the load capacity of retainer of the present invention is improved with this.
To improve stability of the spacing block 2 on retainer, the both sides of each spacing block 2 are respectively arranged with rib 22, rib
22 are structure as a whole with spacing block 2, and rib 22 is fixed on spacing block 2 to have two kinds of forms, and the first is the two of each spacing block 2
Side lower end is respectively arranged with rib 22, and when being coordinated with back-up ring 1, two ribs 22 are fitted be arranged on both sides back-up ring respectively
On 1 inner hole wall.Bearing with this kind of retainer is guided suitable for inner ring.
Another form is that the both sides upper end of each spacing block 2 is respectively arranged with rib 22, and two ribs 22 are fitted setting respectively
In the outside diameter wall of both sides back-up ring 1.Bearing with this kind of retainer is guided suitable for outer ring.
Combined by some pieces of spacing blocks 2 and be arranged between two back-up rings 1, what can be done retainer is more big, and diameter can
To accomplish more than 1 meter, each spacing block 2 is made of the die sinking of same mould, it can be ensured that the precision of retainer.
The bearing for installing retainer of the present invention is applied to inner ring guiding or outer ring guiding, when bearing high-speed rotation, protects
The running center irrelevance for holding frame is smaller, and spacing block 2 can produce radial displacement, now by spacing block 2 both sides rib 22 with
Cooperation between the inner hole wall of back-up ring 1, can effectively limit the radial displacement of spacing block 2, effectively improve spacing block 2 and back-up ring 1
Between cooperation intensity.
Spacing block 2 is connected with two back-up rings 1 through closing-up, rivet through after back-up ring 1 and spacing block 2 with opposite back-up ring 1
Riveted.By this cold carbon riveted attachment structure, retainer can be avoided from being deformed because of high temperature.
With above-mentioned according to desirable embodiment of the invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to its technical scope is determined according to right.
