Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to an impact-resistant deep groove ball bearing. Background Technology

[0002] Deep groove ball bearings are the most common type of rolling bearing, widely used in various mechanical transmission components. In practical applications, many mechanical devices face impact loads, such as automotive engines, mining machinery, and construction equipment. However, existing deep groove ball bearings have shortcomings in impact resistance.

[0003] Currently, on the one hand, the structural design of traditional deep groove ball bearings causes a sudden increase in contact stress between the roller body and the inner and outer rings when subjected to impact. This can easily lead to plastic deformation, fatigue spalling, and other damage to the roller body and the surfaces of the inner and outer rings, shortening the bearing's service life. On the other hand, the lack of effective buffering and shock absorption structures makes it impossible to disperse and absorb impact energy in a timely manner, causing serious damage to the internal structure of the bearing. This, in turn, affects the normal operation of the equipment, increases equipment maintenance costs and downtime, and limits its use. Therefore, it is necessary to develop an impact-resistant deep groove ball bearing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an impact-resistant deep groove ball bearing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant deep groove ball bearing, comprising an inner ring, an outer ring, and a roller assembly disposed between the inner and outer rings, wherein a buffer and damping mechanism is further disposed between the inner and outer rings, and the roller assembly cooperates with the buffer and damping mechanism; the buffer and damping mechanism comprises an elastic buffer layer and damping pads, wherein the elastic buffer layer is disposed between the inner and outer rings near the roller assembly, and the damping pads are evenly distributed within the elastic buffer layer.

[0006] Preferably, the elastic buffer layer is made of polyurethane rubber, which has good elasticity and wear resistance, and can effectively buffer impacts.

[0007] Preferably, the damping shock absorber is made of butyl rubber, which has high damping characteristics and can absorb the vibration energy generated by impact.

[0008] Preferably, the roller assembly includes a plurality of roller bodies, which are equally spaced in the raceway between the inner and outer rings, and the surface of the roller bodies is specially hardened to improve their impact resistance.

[0009] Preferably, both the inner and outer ring raceway surfaces are provided with a friction-reducing and wear-resistant coating, which is a molybdenum disulfide coating, which can reduce the coefficient of friction between the roller body and the raceway and reduce wear.

[0010] Compared with the prior art, this utility model provides an impact-resistant deep groove ball bearing, which has the following beneficial effects:

[0011] 1. This impact-resistant deep groove ball bearing, through its buffer and damping mechanism, allows the elastic buffer layer to buffer the impact force immediately when the bearing is subjected to impact, while the damping damping pad absorbs the vibration energy generated by the impact. This effectively reduces the contact stress between the roller body and the inner and outer rings, and reduces damage such as plastic deformation and fatigue spalling. It solves the problem that existing deep groove ball bearings are prone to damage to the roller body and inner and outer rings and have a short service life when subjected to impact.

[0012] 2. This impact-resistant deep groove ball bearing, through the hardening treatment of the roller body surface and the friction-reducing and wear-resistant coating on the inner and outer ring raceway surfaces, further improves the bearing's impact and wear resistance, reduces the coefficient of friction, reduces the energy loss of equipment, and solves the problem of existing deep groove ball bearings experiencing accelerated wear due to impact, affecting normal equipment operation and increasing maintenance costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Example:

[0021] Please see Figure 1-3 This utility model provides a technical solution: an impact-resistant deep groove ball bearing, including an inner ring 1, an outer ring 2, and a roller assembly 3 disposed between the inner ring 1 and the outer ring 2. A buffer and damping mechanism 4 is also disposed between the inner ring 1 and the outer ring 2. The roller assembly 3 and the buffer and damping mechanism 4 cooperate with each other. The buffer and damping mechanism 4 includes an elastic buffer layer 41 and a damping damping plate 42. The elastic buffer layer 41 is disposed between the inner ring 1 and the outer ring 2 near the roller assembly 3, and the damping damping plate 42 is evenly distributed inside the elastic buffer layer 41.

[0022] Working Principle: When the impact-resistant deep groove ball bearing is subjected to impact during operation, the impact force first acts on the elastic buffer layer 41. The elastic buffer layer 41 deforms due to its good elasticity, buffering most of the impact force. At the same time, the damping and shock-absorbing plates 42 distributed inside the elastic buffer layer 41, with their high damping characteristics, convert the vibration energy generated by the impact into heat energy and other forms of energy and dissipate it, thereby further reducing the impact on the roller assembly 3 and the inner and outer rings. The roller body 31 in the roller assembly 3 has stronger impact resistance due to its special surface hardening treatment, and rolls stably between the inner and outer rings. The friction-reducing and wear-resistant coating 5 on the raceway surface of the inner ring 1 and the outer ring 2 effectively reduces the friction coefficient between the roller body 31 and the raceway, reduces wear, and ensures that the bearing can operate stably for a long time.

[0023] The elastic buffer layer 41 is made of polyurethane rubber; the damping damping pad 42 is made of butyl rubber; the roller assembly 3 includes multiple roller bodies 31, which are evenly distributed in the raceway between the inner ring 1 and the outer ring 2, and the surface of the roller body 31 is specially hardened; the raceway surfaces of the inner ring 1 and the outer ring 2 are both provided with a friction-reducing and wear-resistant coating 5, which is a molybdenum disulfide coating; specifically, the molybdenum disulfide coating can effectively reduce friction and improve the wear resistance of the bearing.
