Description

Technical Field

[0001] The present application relates to the technical field of bearing retainers, and in particular to a combined novel shock-absorbing bearing retainer. Background Art

[0002] When rolling bearings are working, especially when the load is complex and the bearings rotate at high speed, the cages have to bear great centrifugal force, impact and vibration. There is great sliding friction between the cages and the rolling elements, and a lot of heat is generated. The combined effect of force and heat can lead to cage failure, and in severe cases, it can cause the cage to burn and break. Therefore, the cage material is required to have good thermal conductivity, good wear resistance, low friction coefficient, low density, a certain combination of strength and toughness, good elasticity and stiffness. Commonly used bearing cages are mainly divided into metal cages and non-metal cages according to the type of material. There are also composite cages, etc. Bearing cages for special purposes should also meet the requirements of special working conditions, such as high temperature resistance, corrosion resistance, self-lubrication (used in vacuum) or non-magnetic.

[0003] The inventors have discovered that there are at least the following problems in this technology: currently, during the long-term use of the bearing retainer, due to the limited life of the components, it is necessary to perform regular inspection and maintenance on it; however, the existing bearing retainers are basically of one-piece design, and therefore are not convenient for inspection and maintenance. This will result in the inability to maintain the retainer, which will easily accelerate the wear of the bearing retainer and reduce the service life of the bearing retainer; therefore, a new combined shock-absorbing bearing retainer is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present application provides a new combined shock-absorbing bearing retainer, which has the advantages of a detachable connection of the bearing retainer, facilitating subsequent inspection and maintenance, and extending the service life of the bearing retainer. It solves the problem that the bearing retainer adopts an integrated design, which is inconvenient for inspection and maintenance, easily accelerates the wear of the bearing retainer, and reduces the service life of the bearing retainer.

[0005] In order to achieve the above-mentioned purpose of being more convenient during inspection and maintenance and extending the service life of the bearing retainer, the present application provides the following technical solutions: a combined new shock-absorbing bearing retainer, comprising a first retainer, a second retainer installed on the right side of the first retainer, and a splicing assembly installed between the first retainer and the second retainer;

[0006] The splicing assembly includes a first connecting block installed on the surface of the first retaining frame, a second connecting block installed on the outer surface of the second retaining frame, a rotating block installed inside the first retaining frame, a compression spring fixedly connected to the top of the rotating block, a rotating column fixedly connected to the top of the rotating block, a fixing plate fixedly connected to the top of the rotating column, a clamping sleeve fixedly connected to the bottom of the fixing plate, a bolt passing through the inside of the fixing plate, and a screw passing through the inside of the second connecting block.

[0007] In the present application, after the first retaining frame is plugged into the interior of the second retaining frame via the first connecting block, and the second connecting block is located inside the first retaining frame, the fixing plate is pulled to move outward, and the fixing plate is rotated a certain angle so that the clamping sleeve is located inside the second retaining frame and the first connecting block, and the fixing plate is initially limited under the action of the compression spring, and then the bolt is tightened to threadably connect the clamping sleeve and the first connecting block to fix the right half of the fixing plate, and the screw rod passes through the interior of the first retaining frame and is tightened to the interior of the rotating block to fix the second connecting block and the left half of the fixing plate, thereby achieving a more convenient effect of overhauling and maintaining the first retaining frame and the second retaining frame, thereby extending the service life of the device.

[0008] Furthermore, the first retaining frame and the second retaining frame are both fixedly connected with positioning columns inside, and the first connecting block and the second connecting block are respectively clamped in the first retaining frame and the second retaining frame through the positioning columns.

[0009] The beneficial effect of adopting the above further scheme is that when the first connecting block and the second connecting block are respectively located inside the first retaining frame and the second retaining frame, the two positioning columns can play a positioning effect, and try to avoid longitudinal displacement of the first connecting block and the second connecting block, laying a good foundation for subsequent fixation.

[0010] Furthermore, a connecting cavity is provided inside the first retaining frame and the second retaining frame, and the first connecting block and the second connecting block are respectively located inside the first retaining frame and the second retaining frame through the connecting cavity.

[0012] Furthermore, a mounting cavity is provided inside the first retaining frame, the rotating block and the compression spring are located inside the first retaining frame through the mounting cavity, and the compression spring slides on the outer surface of the rotating column.

[0013] The beneficial effect of adopting the above further solution is that the rotating block and the compression spring can be located inside the first retaining frame via the mounting cavity, and when the rotating block slides up and down, the mounting cavity can also play a role of limiting guidance.

[0014] Furthermore, a rotating column hole is provided inside the first retaining frame, and the rotating column rotates inside the first retaining frame through the rotating column hole.

[0015] The beneficial effect of adopting the above further solution is: ensuring that the rotating column hole can play a limiting role when the rotating column is slightly rotated, paving the way for subsequent clamping and limiting.

[0016] Furthermore, the fixing plate is in the shape of an arc-shaped plate, a bolt hole is provided inside the clamping sleeve, the bolt hole penetrates and extends to the inside of the first connecting block, and the bolt is detachably connected to the first connecting block.

[0017] The beneficial effect of adopting the above further solution is that the fixing plate can be securely fixed by bolts after being clamped with the first connecting block through the clamping sleeve, which provides convenience for subsequent maintenance and disassembly.

[0018] Furthermore, a sleeve hole is provided inside the second retaining frame, and the sleeve hole extends to the inside of the first connecting block. The pressing sleeve is located inside the second retaining frame and the first connecting block through the sleeve hole.

[0019] The beneficial effect of adopting the above further scheme is that after the clamping sleeve can limit the first connecting block inside the second retaining frame, the first connecting block will not only be limited by the bolt at one place, but can be limited again by the clamping sleeve, thereby further improving the reliability of the connection by adopting double insurance.

[0020] Furthermore, a connecting through hole is provided inside the second connecting block, and the connecting through hole penetrates and extends into the first retaining frame. A screw blind hole is provided inside the rotating block, and the screw is detachably connected to the rotating block through the screw blind hole.

[0021] The beneficial effect of adopting the above further scheme is: after the fixed plate is attached to the outer surface of the first retaining frame, the rotating block is located on the inner bottom wall of the installation cavity. At this time, the screw is inserted and tightened, and the second connecting block, the first retaining frame and the second connecting block can be connected into a whole, ensuring that the left half of the fixed plate is not in a loose state.

[0022] Compared with the prior art, the present application provides a new type of combined shock-absorbing bearing retainer, which has the following beneficial effects:

[0037] It should be noted that rubber bearings use rubber as a shock-absorbing material, which can provide good elasticity and shock absorption performance. Rubber bearings are usually used in building structures, vibrating machinery, and transportation. The main feature of shock-absorbing bearings is that they contain special shock-absorbing materials between their inner and outer rings, such as rubber or other polymer materials. These materials can provide a certain degree of elasticity and shock absorption when the bearing is in operation. When the equipment is running and vibrating, the shock-absorbing material can deform to absorb energy, thereby reducing the vibration and impact transmitted to other parts of the equipment.
