Description

Technical Field

[0001] The utility model relates to the technical field of bearing rings, in particular to an impact-resistant bearing ring component. Background Art

[0002] Bearings are a common mechanical part used to support and reduce friction during rotational motion. Bearings are usually composed of an inner ring, an outer ring, rolling elements and a cage. Their basic principle is to transfer loads and reduce friction by the rolling of rolling elements between the inner and outer rings. The inner and outer rings are also called bearing rings, which are important parts of the bearing.

[0003] The Chinese patent with publication number: CN220227542U discloses an impact-resistant bearing ring assembly. The patent can improve its impact resistance through the outer ring and inner ring of steel alloy material, and can shield and protect the gap between the outer ring and the inner ring through a cover to prevent impurities from entering between the outer ring and the inner ring. However, the above patent only uses alloy material to improve the impact resistance of the bearing ring assembly. When it is hit by external force, it still cannot prevent the bearing ring from being hit, which is easy to generate additional impact force between the outer ring, the inner ring and the rolling element, and even cause dislocation and damage of the bearing, thereby affecting the normal use of the equipment. For this reason, we propose an impact-resistant bearing ring assembly. Utility Model Content

[0008] As a further description of the above technical solution:

[0009] The airbag is located at the front and rear parts of the top and bottom of the connecting ring, and the airbag is located between the upper and lower force-bearing plates.

[0010] As a further description of the above technical solution:

[0011] The connecting mechanism includes a slot, a contraction cavity, a connecting spring, a connecting plate, a fixing rod, an insert block and a fixing hole. A slot is provided in the middle of the top of the connecting block, a contraction cavity is provided in the middle of the front and rear sides of the slot, a connecting spring is fixedly connected in the middle of the mutually distant sides of the contraction cavities of the front and rear parts, connecting plates are fixedly connected at the opposite ends of the connecting springs of the front and rear parts, fixing rods are fixedly connected in the middle of the opposite sides of the connecting plates of the front and rear parts, insert blocks are symmetrically fixedly connected to the bottom of the force-bearing plate, and fixing holes are provided in the middle of the front and rear sides of the insert block.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. When the impact-resistant bearing ring assembly is impacted, the force-bearing plate contracts, so that the connecting block drives the sealing plate to move, compresses the compression spring, and cushions the impact through the deformation of the compression spring. At the same time, when the sealing plate moves, the air inside the installation cavity is compressed into the connecting pipe and enters the airbag, causing the airbag to expand, thereby avoiding contact between the force-bearing plate and the bearing, improving the impact resistance of the bearing ring, avoiding damage to the bearing ring, and increasing the service life of the bearing ring.

Then, a new stress plate is installed, so that the insert is embedded in the slot, and the fixing rod is squeezed, so that the fixing rod squeezes the connecting spring. When the fixing hole is aligned with the fixing rod, the fixing rod is embedded in the fixing hole by resetting the connecting spring, and the replacement is completed, thereby facilitating replacement when the stress plate is damaged, making replacement more convenient and improving the practicality of the device.

[0040] In specific use, when the force plate 560 is hit, the technical personnel in this field will contract under the force, so that the connecting block 550 drives the sealing plate 540 to move, squeeze the compression spring 530, and cushion the impact through the deformation of the compression spring 530. At the same time, when the sealing plate 540 moves, the air inside the installation cavity 520 is compressed into the connecting pipe 570 and enters the airbag 580, so that the airbag 580 expands, thereby avoiding the contact between the force plate 560 and the bearing, improving the impact resistance, and when the force plate 560 is damaged, Directly pull the force-bearing plate 560 so that the fixing hole 670 squeezes the fixing rod 650, causing the fixing rod 650 to shrink inside the shrinkage cavity 620, pull out the force-bearing plate 560, and then install the new force-bearing plate 560 so that the plug block 660 is embedded in the slot 610, squeeze the fixing rod 650, causing the fixing rod 650 to squeeze the connecting spring 630, and when the fixing hole 670 is aligned with the fixing rod 650, the connecting spring 630 is reset so that the fixing rod 650 is embedded in the fixing hole 670 to complete the replacement.
