Description

Technical Field

[0001] This utility model relates to the field of bearings, and in particular to an impact-resistant plastic bearing. Background Technology

[0002] Bearings are components that support shafts, enabling them to rotate and reducing friction. They consist of an inner ring, outer ring, rolling elements, and a cage. The rolling elements are evenly arranged between the inner and outer rings, and their shape, size, and number directly affect the bearing's load capacity and performance. There are various types of bearings, such as deep groove ball bearings, self-aligning ball bearings, and thrust ball bearings. Each type is suitable for different machinery and equipment, playing a vital role in supporting, rotating, and reducing friction and wear. Plastic bearings are components in electromechanical equipment, fitness equipment, etc., and are mainly divided into plastic rolling bearings and plastic sliding bearings. They possess characteristics such as good corrosion resistance, high mechanical strength, light weight, low manufacturing cost, noiseless operation, vibration absorption, wear resistance, and self-lubrication, and are suitable for high and low temperature operation. Plastic bearings are widely used in industrial production, bottling equipment, conveying systems, food industry, and other fields. Their customizability, water resistance, dirt resistance, and dustproof functions make them an optimal choice in various environments. Plastic bearings are often subjected to impacts from external objects during use, and these impacts have a certain probability of causing damage, which in turn affects the normal use of the plastic bearings and reduces their service life. Therefore, an impact-resistant plastic bearing is needed to solve the above problems. Utility Model Content

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an impact-resistant plastic bearing includes a plastic bearing body 1. A first impact-resistant component 2 is fixedly sleeved on the plastic bearing body 1. The first impact-resistant component 2 consists of a buffer rubber airbag 8 and a connecting rubber sheet 9. Several buffer rubber airbags 8 and connecting rubber sheets 9 are provided, and the connecting rubber sheet 9 connects two adjacent buffer rubber airbags 8 together. Two second impact-resistant components 3 are symmetrically fixedly installed at both ends of the plastic bearing body 1. The second impact-resistant component 3 consists of a hard base ring 10, a wave spring 11, and a protective rubber ring 12. The wave spring 11 and the protective rubber ring 12 are respectively installed at both ends of the hard base ring 10. The plastic bearing body 1 consists of an inner ring 4, an outer ring 5, a cage 6, and balls 7. The outer ring 5 is sleeved on... On the outer side of the inner ring 4, there are several balls 7, all of which are movably installed between the inner ring 4 and the outer ring 5. The cage 6 is also located between the inner ring 4 and the outer ring 5, and the cage 6 is movably connected to several balls 7. Thus, by setting the first anti-impact component 2 and the second anti-impact component 3 on the plastic bearing body 1, the first anti-impact component 2 and the second anti-impact component 3 can block objects that collide with the plastic bearing body 1 to a certain extent, thereby reducing the probability that the plastic bearing body 1 will be directly impacted by external objects. At the same time, the first anti-impact component 2 and the second anti-impact component 3 can buffer the impact force generated by the impacting object, thereby reducing the probability of damage to the plastic bearing body 1 and ultimately improving the service life of the plastic bearing body 1.

[0022] Specifically, the first impact-resistant component 2 is fixedly sleeved on the outer ring 5 of the plastic bearing body 1. The buffer rubber airbag 8 and the connecting rubber sheet 9 on the first impact-resistant component 2 are fixedly connected, and the buffer rubber airbag 8 is also fixedly connected to the outer ring 5 on the plastic bearing body 1. The buffer rubber airbag 8 is fixed to the outer wall of the outer ring 5 with glue. When an external object impacts the first impact-resistant component 2 from the front, the buffer rubber airbag 8 on the first impact-resistant component 2 will undergo elastic deformation upon impact. In this process, the impact force generated by the impact of the external object can be weakened, thereby reducing the impact force on the plastic bearing body 1 and thus reducing the probability of damage to the plastic bearing body 1. When the impact force disappears, the buffer rubber airbag 8 will elastically recover.

[0023] Specifically, the hard base ring 10 on the second impact-resistant component 3 is fixedly connected to the wave spring 11 and the protective rubber ring 12, and the wave spring 11 is also fixedly connected to the outer ring 5 on the plastic bearing body 1. When an external object impacts the second impact-resistant component 3 from the front, the impacting object will move the hard base ring 10 and the protective rubber ring 12 on the second impact-resistant component 3 toward the plastic bearing body 1. At this time, the hard base ring 10 will squeeze and deform the wave spring 11. During the elastic deformation of the wave spring 11, the impact force generated by the impact of the external object can be weakened, thereby reducing the impact force on the plastic bearing body 1 and reducing the probability of damage to the plastic bearing body 1. When the impact force disappears, the wave spring 11 will return to its original state, and under the elastic support force of the wave spring 11, the hard base ring 10 and the protective rubber ring 12 will also move outward and return to their original state.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
