Description

Technical Field

[0001] This utility model belongs to the field of bearing technology, and more specifically, it relates to an anti-vibration bearing cage. Background Technology

[0002] The bearing cage can evenly separate the rolling elements to prevent them from colliding and rubbing against each other. In order to buffer the vibration of the bearing during operation, the cage is usually equipped with anti-vibration bars, rubber bushings and other buffer structures to absorb and buffer the vibration and impact generated by the bearing during operation and reduce the vibration amplitude.

[0003] For example, CN219809286U discloses a bearing cage, including a frame body, which comprises a top ring, a bottom ring, and several support members evenly distributed circumferentially between the top and bottom rings. Windows for mounting rolling elements are formed between adjacent support members. The cage includes an axial limiting mechanism and a radial limiting mechanism. The radial limiting mechanism includes a block disposed on the top ring and a corresponding slot on the bottom ring. Upper and lower adjacent frames are axially fixed by the insertion and engagement of the block and the slot. The radial limiting mechanism includes a retaining spring. A corresponding retaining groove is provided on the block. After the block is inserted into the slot, its retaining groove extends beyond the slot. The upper and lower adjacent frames are axially fixed by the retaining spring engaging with the retaining groove. This utility model provides a bearing cage in which multiple cages can be combined and move synchronously as needed.

[0004] Based on the above, in bearings used in vibration environments, the grease is prone to uneven distribution due to vibration, resulting in insufficient lubrication of the rolling elements in certain areas. This leads to inconsistent wear on different parts of the rolling elements, affecting the balance of the rolling elements and the operational stability of the bearing. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an anti-vibration bearing cage to solve the problem that in bearings used in vibration environments, the grease is easily unevenly distributed due to vibration, leading to insufficient lubrication of the rolling elements in certain areas, resulting in inconsistent wear of different parts of the rolling elements, affecting the balance of the rolling elements, and affecting the operational stability of the bearing.

[0006] The purpose and effect of this anti-vibration bearing cage are achieved by the following specific technical means:

Two cage bodies are provided, and multiple engineering plastic pads are provided, evenly distributed and inserted into the inner sides of the two cage bodies, which are then fixedly connected by bolts.

[0008] Furthermore, the detection structure includes sliding detection rods and limiting mounting rods; multiple sliding detection rods are provided, and the multiple sliding detection rods are evenly distributed and slidably connected to the inner sides of the two cage bodies; multiple limiting mounting rods are provided, and the multiple limiting mounting rods are respectively fixedly connected to the middle of the multiple sliding detection rods.

[0009] Furthermore, the detection structure also includes a detection pressure sensor and a reset rubber elastic element; multiple detection pressure sensors are provided, and the multiple detection pressure sensors are respectively fixedly connected to the ends of multiple limiting mounting rods; multiple reset rubber elastic elements are provided, and the multiple sliding detection rods are respectively elastically connected to the two cage bodies through the multiple reset rubber elastic elements.

[0010] Furthermore, the extrusion structure includes a fixed mounting plate and position indicator pins; multiple fixed mounting plates are provided, and the multiple fixed mounting plates are evenly distributed and fixedly connected to the outer sides of the two cage bodies; multiple position indicator pins are provided, and the multiple position indicator pins are respectively fixedly connected to the middle of the multiple fixed mounting plates.

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

[0014] This invention uses engineering plastic pads to absorb vibration and impact, reducing collisions and friction of rolling elements caused by vibration, and mitigating the impact of vibration on bearing stability. A corrugated rubber elastic element pushes a grease extrusion plate to evenly distribute grease to the contact areas of the rolling elements, preventing uneven grease distribution due to vibration and ensuring sufficient lubrication of all parts of the rolling elements. This avoids inconsistent wear. The invention can monitor the pressure changes of the engineering plastic pads in real time. When the pads soften due to high temperature, an alarm is issued to remind operators to cool the bearing promptly, preventing rolling element jamming or detachment caused by continued bearing operation after cage softening. When grease is insufficient, an alarm is automatically issued to remind operators to add grease. Furthermore, the engineering plastic pads can be replaced individually, eliminating the need to replace the entire cage when wear occurs, reducing maintenance costs and improving bearing stability and service life.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a vibration-resistant bearing cage, including a cage body 1, engineering plastic pads 2, grease storage tanks 3, a detection structure, grease extrusion plates 4, warning pressure sensors 5, and corrugated rubber elastic elements 6. Two cage bodies 1 are provided, and multiple engineering plastic pads 2 are provided, evenly distributed and inserted into the inner sides of the two cage bodies 1, which are then fixedly connected by bolts. Multiple grease storage tanks 3 are provided, evenly distributed and located inside the multiple engineering plastic pads 2. The detection structure is located inside the cage body 1. Multiple grease extrusion plates 4 are provided, slidably connected to the inner sides of the multiple grease storage tanks 3. Multiple warning pressure sensors 5 are provided, fixedly connected to the outer sides of the multiple grease extrusion plates 4. Multiple corrugated rubber elastic elements 6 are provided, and the multiple grease extrusion plates 4 are elastically connected to the multiple engineering plastic pads 2 through the multiple corrugated rubber elastic elements 6.

[0027] The detection structure includes a sliding detection rod 103 and a limiting installation rod 104. Multiple sliding detection rods 103 are provided, and the multiple sliding detection rods 103 are evenly distributed and slidably connected to the inner side of the two retainer bodies 1. Multiple limiting installation rods 104 are provided, and the multiple limiting installation rods 104 are respectively fixedly connected to the middle of the multiple sliding detection rods 103.

[0028] The detection structure also includes a detection pressure sensor 105 and a reset rubber elastic element 106; multiple detection pressure sensors 105 are provided, and multiple detection pressure sensors 105 are respectively fixedly connected to the ends of multiple limit mounting rods 104; multiple reset rubber elastic elements 106 are provided, and multiple sliding detection rods 103 are elastically connected to two cage bodies 1 through multiple reset rubber elastic elements 106.

[0029] The specific usage and function of this embodiment: Multiple audible and visual alarms are installed on the outside of the equipment where the bearing is installed, with each bearing corresponding to one audible and visual alarm. The detection pressure sensor 105 and the warning pressure sensor 5 are both connected to the control circuit of the audible and visual alarms via a wireless transmission module. After the bearing cage is assembled, the engineering plastic pad 2 continuously applies pressure to the sliding detection rod 103, causing the sliding detection rod 103 to compress and reset the rubber elastic element 106 and press the limiting mounting rod 104 and the detection pressure sensor 105. At this time, the detection pressure sensor 105 senses a large pressure. When the engineering plastic pad 2 softens due to high temperature, the pressure on the sliding detection rod 103 decreases, and the restoring force of the reset rubber elastic element 106 pushes the sliding detection rod 103 outward. At this time, the pressure sensed by the detection pressure sensor 105 decreases, and the wireless transmission module transmits the electrical signal emitted by the detection pressure sensor 105 to the control circuit of the audible and visual alarm, causing the audible and visual alarm to sound an alarm, reminding the staff that the bearing temperature is too high, so that the staff can cool the bearing in time, and also prevent the rolling elements from jamming or falling off due to insufficient support force after the cage softens.

[0030] Example 2:

[0031] As attached Figure 2 To be continued Figure 6 As shown:

[0032] Based on Embodiment 1, an extrusion structure is also included; the extrusion structure is disposed on the inner side of the engineering plastic pad 2.

[0033] The extrusion structure includes a fixed mounting plate 101 and a position indicator needle 102; multiple fixed mounting plates 101 are provided, and the multiple fixed mounting plates 101 are evenly distributed and fixedly connected to the outside of the two retainer bodies 1; multiple position indicator needles 102 are provided, and the multiple position indicator needles 102 are respectively fixedly connected to the middle of the multiple fixed mounting plates 101.

[0034] The extrusion structure also includes position limiting rods 201 and anti-slip rubber rings 202; multiple position limiting rods 201 are provided, and multiple position limiting rods 201 are slidably connected to the middle of multiple engineering plastic pads 2 respectively. Multiple position limiting rods 201 are inserted into two retainer bodies 1 respectively, and scales are provided on the outer side of multiple position limiting rods 201; multiple anti-slip rubber rings 202 are provided, and multiple anti-slip rubber rings 202 are respectively bonded to the outer side of multiple position limiting rods 201.

[0035] The extrusion structure also includes a limiting extrusion plate 203 and a limiting extrusion block 204; multiple limiting extrusion plates 203 are provided, and multiple limiting extrusion plates 203 are respectively fixedly connected to the inner side of multiple position limiting rods 201; multiple limiting extrusion blocks 204 are provided, and multiple limiting extrusion blocks 204 are evenly distributed and fixedly connected to the outer side of multiple limiting extrusion plates 203.

[0036] The specific usage and function of this embodiment are as follows: When assembling the cage body 1, first insert the engineering plastic pad 2 into the corresponding position, then rotate the position limiting rod 201 so that the scale on the position limiting rod 201 is aligned with the position indicator 102 on a fixed mounting plate 101. At this time, the limiting squeezing block 204 on the outside of the limiting squeezing plate 203 will push the grease squeezing plate 4 outward, so that the grease squeezing plate 4 is fixed inside the grease storage tank 3. At this time, add high viscosity grease to the grease storage tank 3. After installing the rolling elements, rotate the position limiting rod 201 in the opposite direction so that the scale on the position limiting rod 201 is aligned with the position indicator 102 on the other fixed mounting plate 101. At this time, the limiting squeezing block 204 and the grease The extrusion plates 4 are staggered, and the corrugated rubber elastic element 6 continuously pushes the grease extrusion plates 4, making the grease extrusion plates 4 push the grease to fit tightly against the rolling elements. At the same time, it also prevents the grease from flowing and ensures uniform distribution. The anti-slip rubber ring 202 can increase the rotational resistance of the position limiting rod 201 and reduce the autonomous rotation of the position limiting rod 201. When the grease is too low, the warning pressure sensor 5 will contact the engineering plastic pad 2 under the push of the corrugated rubber elastic element 6. At this time, the warning pressure sensor 5 is under pressure and sends an electrical signal to the control circuit of the audible and visual alarm through the wireless transmission module, causing the audible and visual alarm to sound an alarm and remind the staff to add grease. When the cage is worn, the damaged engineering plastic pad 2 can be replaced separately.
