Description

Technical Field

[0001] This utility model belongs to the field of self-aligning roller bearing technology, and more specifically, it relates to a combined MB type vibrating screen special retainer. Background Technology

[0002] The retainer of the MB type self-aligning roller bearing for vibrating screens is usually composed of two solid brass retainers. Each retainer corresponds to a row of spherical rollers, and each row of rollers is supported by an independent retainer. This ensures that the two rows of rollers can synchronously adapt to the bending or misalignment of the shaft during self-alignment and avoid mutual interference. The double retainer structure distributes the centrifugal force and friction of the rollers, making it particularly suitable for high-speed or heavy-load scenarios such as vibrating screens. Existing combined MB type vibrating screen retainers generally consist of a main frame and multiple retainer arms for mounting the rollers.

[0003] Existing application number: CN202020653969.X, this utility model discloses a combined MB-type vibrating screen retainer, including a retainer base. Limiting protrusions are fixedly installed on both sides of the retainer base, and a placement groove is formed between the limiting protrusions. The limiting protrusions are arranged in a ring on the outer side of the retainer base. The outer surface of the limiting protrusions has a chamfered portion. A cylindrical roller is arranged inside the placement groove. A clamping mechanism is arranged inside the limiting protrusions. A locking mechanism is connected to the joint of the retainer base. The clamping mechanism consists of a clamping post, a fixing slot, a connecting head, a protective pad, and a telescopic spring. One end of the clamping post extends into the interior of the limiting protrusion, and the fixing slot is opened inside the limiting protrusion. This combined MB-type vibrating screen retainer can prevent the sealing ring from affecting the rolling of the cylindrical rollers on the retainer, and can facilitate the installation and disassembly of the retainer.

[0004] Based on the above, when the vibrating screen is running under high load and high frequency vibration conditions, the working surface of the retainer arm in contact with the roller is prone to wear. However, the existing retainer arm lacks a visual wear indication structure, and it is necessary to rely on disassembly for inspection or experience judgment, which leads to untimely maintenance and may cause consequences such as roller detachment and bearing failure. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a combined MB-type vibrating screen retainer. This solves the problem that when existing vibrating screens operate under high load and high frequency vibration conditions, the working surface of the retainer arm in contact with the roller is prone to wear. However, existing retainer arms lack a visual wear indicator structure, requiring disassembly for inspection or experience-based judgment, which leads to untimely maintenance and may result in roller detachment, bearing failure, and other consequences.

[0006] The purpose and effect of this utility model, a combined MB-type vibrating screen retainer, are achieved by the following specific technical means:

[0007] A combined MB-type vibrating screen retainer includes a main frame, retainer arms, wear indicator holes, wear indicator blocks, auxiliary lubrication grooves, auxiliary lubrication sponge blocks, stabilizing operation components, and transport auxiliary components. Multiple retainer arms are provided, and these arms are distributed and fixedly connected to the front of the main frame. Multiple wear indicator holes are provided, distributed on the outer sides of the multiple retainer arms. Multiple wear indicator blocks are provided, each fixedly connected inside one of the multiple wear indicator holes. Multiple auxiliary lubrication grooves are provided, distributed on the left and right sides of the multiple retainer arms. Multiple auxiliary lubrication sponge blocks are provided, each disposed within one of the multiple auxiliary lubrication grooves. Multiple sets of stabilizing operation components are provided, distributed behind the multiple retainer arms. The transport auxiliary components are located inside and at the front of the main frame.

[0008] Furthermore, the cross-section of the wear indicator hole is a rectangular slot structure, and the slot length of the wear indicator hole is adapted to the overall length of the wear indicator block.

[0009] Furthermore, the cross-section of the auxiliary lubrication groove is a rectangular groove structure, and the groove length of the auxiliary lubrication groove is adapted to the overall length of the auxiliary lubrication sponge block.

[0010] Furthermore, the stable operation component includes: a buffer pad; two buffer pads are provided, and the two buffer pads are respectively fixedly connected to the left and right sides of the rear end of the retainer arm.

[0011] Furthermore, the transport auxiliary component includes: a first positioning hole and a first positioning post; the first positioning hole is formed inside the main frame; the first positioning post and the first positioning hole are interference-fitted.

[0012] Furthermore, the transport auxiliary component also includes: a second positioning hole and a second positioning post; the second positioning hole is opened inside a retainer arm at the bottom; the second positioning post is fixedly connected to the front of the first positioning post, and the second positioning post and the second positioning hole are interference-fitted.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, wear indicator holes are made on the outside of the retainer arm and wear indicator blocks are embedded to achieve visual wear monitoring. Lubricating sponge blocks are set on both sides of the retainer arm. During operation, the sponge blocks slowly release grease to continuously lubricate the roller contact parts, effectively reducing rotational noise and reducing the risk of dry friction. Nylon or rubber buffer pads are attached to the rear end of the retainer arm. Their elasticity absorbs the vibration energy of the roller operation, reduces rigid collisions, further reduces bearing operating noise, and improves stability under high load vibration conditions.

[0015] Secondly, with the cooperation of transportation auxiliary components, the two retainers used for one MB type bearing can be assembled and transported together, thereby reducing the overall volume during transportation, making it easier to handle and operate, and making it more convenient and intuitive to count the quantity.

[0016] This invention enables visual wear monitoring of the retainer arm, significantly reducing wear and noise between the retainer arm and rollers during bearing operation. It also allows for the assembly and transport of two retainers compatible with a single set of MB type bearings, effectively reducing transport volume and facilitating handling and quantity counting.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0027] This utility model provides a combined MB-type vibrating screen retainer, including a main frame 1, retainer arms 2, wear marking holes 3, wear marking blocks 301, auxiliary lubrication grooves 4, auxiliary lubrication sponge blocks 401, and stabilizing components.

Multiple auxiliary lubrication sponge blocks 401 are provided, and are respectively disposed inside the multiple auxiliary lubrication grooves 4. Multiple sets of stabilizing components are provided, distributed behind the multiple retainer arms 2.

[0028] The cross-section of the wear marking hole 3 is a rectangular slot structure, and the slot length of the wear marking hole 3 is adapted to the overall length of the wear marking block 301.

[0029] The auxiliary lubrication groove 4 has a rectangular groove structure in its cross-section, and the groove length of the auxiliary lubrication groove 4 is adapted to the overall length of the auxiliary lubrication sponge block 401.

[0030] The stable operation component includes: buffer pads 5; two buffer pads 5 are provided, and the two buffer pads 5 are fixedly connected to the left and right sides of the rear end of the retainer arm 2 respectively.

[0031] The specific usage and function of this embodiment are as follows: During use, the wear indicator block 301 is fixedly connected to the inside of the wear indicator hole 3 with glue. If the retainer arm 2 is severely worn during long-term operation, causing the wear indicator block 301 to become exposed, it indicates that the entire retainer needs to be replaced in time. When assembling, the auxiliary lubrication sponge block 401 is first soaked in grease, then inserted into the auxiliary lubrication groove 4, and then the roller is assembled. Later, when the roller is running, the grease in the auxiliary lubrication sponge block 401 is slowly released, effectively reducing the noise of the roller when rotating. The buffer pad 5 is made of nylon or rubber and is glued to the left and right sides of the rear end of the retainer arm 2, which can effectively absorb the vibration noise of the roller during operation.

[0032] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes a transportation auxiliary component, which is located inside and in front of the main frame 1.
