We all know that there are many types of raw materials for related bearings, and different industries have different types of applications. The commonly used raw materials for bearings include three categories: metal composite materials, porous structured metal composite materials, and non-metallic materials.

The noise of bearings not only affects the quality of use, but also brings a lot of trouble to mechanical equipment. In general, there will be some noise during the use of bearings, and the invasion of foreign substances can directly cause certain noises during the operation of bearings, or improper lubrication, inadequate installation, etc., which can cause various noises from the bearings. What methods can make the use of bearings less noisy?

Assembly of sliding bearings: Sliding bearings are a type of bearing with sliding friction properties, characterized by smooth operation, reliability, low noise, and the ability to withstand heavy loads and large impact loads. They can be divided into integral, split, and tile types according to different structural forms. (1) The assembly of integral sliding bearings, commonly known as shaft sleeves, is also the simplest form of sliding bearings. It is mainly assembled by pressing and hammering, and in special cases, hot fitting is used. Most shaft sleeves are made of copper or cast iron, and assembly should be careful. Wooden hammers or hammers can be used to hit wooden blocks during assembly. When the interference size tolerance is large, a press is used to press in. Regardless of whether it is knocked in or pressed in, it is necessary to prevent tilting. After assembly, the oil tank and oil hole should be in the required position.

Cause analysis:

It can be generated by the vibration and collision between the retainer and the rolling element, regardless of the type of lubricating grease, and is more likely to occur when subjected to torque, load, or large radial clearance.

Cage, also known as bearing cage, refers to a bearing component that partially wraps all or part of the rolling element and moves with it, used to isolate the rolling element. It usually guides the rolling element and keeps it inside the bearing.

Rolling bearings use various mechanical equipment, and the increasingly stringent market requirements for imported bearings require equipment and other properties, resulting in increasingly diverse performance. To select the most suitable bearing from a large number of structures, sizes, and requires different angles. When choosing imported bearings, it is generally believed that the difficulty arrangement of installation and removal, the size of imported bearings, and the market for bearings, as well as the space allowed, generally determine the structure of imported bearings. Comparative research on the design lifespan of various machinery and the limitations of various durable imported bearings, while determining the bearing size.

The world's smallest steel ball bearing is located in Tokyo, Japan. Meibei Co., Ltd. announced that its steel balls have been awarded the Guinness World Record for the smallest commercial steel ball bearing. Representatives from Guinness World Records Co., Ltd. have certified that the outer diameter of its steel balls is only 1.4978 millimeters. Maybella has been trying to prove its ability to produce the smallest mass-produced bearings.

Using a sound meter to check the size and sound quality of the rolling sound of the running bearings, even if there is slight peeling or other damage to the bearings, abnormal and irregular sounds can be distinguished by using a sound meter.

Using auditory perception to identify irregular movements is a common method. For example, using an electronic stethoscope to detect abnormal noise in a certain part is often a method used by experienced operators. If the bearings are in good continuous operation, they will emit a low whining sound. If sharp hissing, squeaking, and other irregular sounds are emitted, it often indicates that the bearing is in poor continuous rotation condition.

Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. With the increasing demand for bearings, problems such as premature damage and short lifespan of bearings are troubling every mechanical enthusiast.

The equipment manufacturing industry is the foundation of a country's industrial development and a core component of the manufacturing industry, responsible for providing production technology and equipment for the national economy and defense construction. Establishing a strong equipment manufacturing industry and achieving the localization of high-end equipment is the fundamental guarantee for improving China's comprehensive national strength and achieving modern industrialization.

1. Requirements for monitoring rolling bearings using magnetic plugs

(1) Magnetic plugs are only suitable for monitoring critical main bearings lubricated with oil and returned through dedicated pipelines.

(2) The magnetic plug should be installed as close as possible to the main bearing being monitored, on the main channel for oil return, without the obstruction of a filter screen, oil pump, or other hydraulic components in the middle.

(3) In order to improve monitoring efficiency, a rotary oil storage tank with return oil inlet and outlet can be made. The oil reservoir should be designed in an inverted conical table shape, and the magnetic plug should be installed at the bottom of the oil reservoir. The oil inlet of the oil reservoir should be tilted at a certain angle to allow lubricating oil to enter from the tangential direction. This is beneficial for the separation of abrasive particles from the lubricating oil that circulates, settling at the bottom, entering the magne
