What is the standard for adding grease to turntable bearings?The standard for adding grease to turntable bearings should be determined according to the requirements and usage of the equipment manufacturer. Generally speaking, the amount and cycle of grease addition should follow the following standards: 1. Requirements of equipment manufacturers: The lubrication requirements of turntable bearings of different brands and models may be slightly different. Therefore, before adding grease, you should first consult the instructions provided by the equipment manufacturer to understand its lubrication requirements, grease type and amount of grease addition. 2. Bearing operation time: The amount and cycle of grease addition will also be affected by the equipment operation time and use environment. Generally speaking, the longer the equipment works and the greater the load, the faster the grease consumption rate will be, and the cycle of adding grease needs to be shortened. 3. Working environment: The grease consumption rate of turntable bearings will be different in different working environments. For example, for equipment working in high temperature, high humidity or dusty environment, the amount and cycle of grease addition need to be adjusted accordingly. In short, before adding grease, you should understand the requirements of the equipment manufacturer, and determine the amount and cycle of grease addition based on the equipment operation time and use environment. For more complicated situations, you may consider asking specialized equipment maintenance personnel for advice and assistance.

Deep groove ball bearing materialsDeep groove ball bearing is a widely used rolling bearing, which is characterized by low friction resistance, high rotation speed, and can withstand radial load or combined load acting simultaneously in radial and axial directions. The materials of deep groove ball bearings include but are not limited to carbon steel, bearing steel, stainless steel, plastic, ceramics, etc. Among them, bearing rings and steel balls are usually made of GCR15 (AISI 52100) refined bearing steel, and the retainer is stamped from 08F high-quality cold-rolled steel strip.Materials for deep groove ball bearings also include high-carbon chromium steel, a heat-treated material that has excellent strength and wear resistance and is suitable for high load and high-speed conditions. Stainless steel materials have excellent corrosion resistance and are often used in humid or chemically corrosive environments. Ceramic materials such as alumina ceramics and silicon oxynitride ceramics have the characteristics of high strength, high hardness, and low friction coefficient, and are suitable for high-speed, high-temperature, and high-precision application scenarios.In addition, there are miniature deep groove ball bearings, which are made of equally diverse materials, including carbon steel, stainless steel, plastic, ceramics, etc. Among them, various types of bearings with an outer diameter of less than 9.525mm in the inch series are also widely used.On the assembly drawing, the materials of deep groove ball bearings are usually clearly marked, including but not limited to material type, hardness grade, accuracy grade, etc., to ensure their suitability and performance in specific applications.

SKF applies for a health diagnosis patent for electric vehicle motor bearings to monitor the health status of motor bearingsAccording to news from the financial industry on October 28, 2024, information from the State Intellectual Property Office shows that SKF has applied for a patent titled "Health Diagnosis Method and System for Motor Bearings for Electric Vehicles", with the public number CN 118817306 A. The application date is April 2023.The patent abstract shows that the present invention provides a health diagnosis method and system for motor bearings of electric vehicles. The method may include: collecting parameter data related to the motor bearing; preprocessing the parameter data to generate preprocessed parameter data; performing feature extraction processing on the preprocessed parameter data to obtain one or more features; and inputting the obtained one or more features into an anomaly detection model, and diagnosing the health status of the motor bearing based on the output of the anomaly detection model, wherein the parameter data includes the At least one of current data associated with the motor of the electric vehicle and rotor rotation data associated with the rotor of the motor.The health diagnosis method and system of the motor bearing of the present invention can be used to monitor the health status of the motor bearing without the need to additionally set up a specific acceleration sensor in the electric drive system, thereby avoiding an increase in cost.

Focus on the 2024 World Robot Conference held in Beijing. This conference received support from 26 international organizations. The number of international participants increased by 9.7% compared with last year, setting a record high. Many foreign companies and visitors are increasingly interested in China’s “intelligent manufacturing”. At the exhibition site, a robot spherical bearing produced by a Chinese company attracted widespread attention. Exhibitors said that such products are very popular in overseas markets. North American sales director Jerry Nick said: "We mainly sell spherical bearings and connecting rod assemblies produced in China. Although there are similar companies in my country, Chinese companies have done an excellent job in mass-producing these products. This time The conference is large-scale and covers a wide range of fields from industrial robots to bionic robots.China's manufacturing industry has received high praise overseas and has also attracted the attention of many foreign manufacturers. A sensor originating from a Korean university is attracting attention for its potential applications in bionic robotics and security. The huge potential of the Chinese market attracts these engineers. Li Runxing, head of the exhibiting company, said: “Our hand devices have built-in sensors that can sense and grasp objects like humans. We believe that China is a key market for the rapid growth of the global robotics industry, and China is very active in robotics technology and manufacturing. We are actively preparing and hope to introduce our sensors to the Chinese market and show them to Chinese customers.In addition to humanoid robots and bionic robots of various shapes, various service robots have also attracted the interest of a large number of audiences. At the venue, service robots that can make coffee and pancakes were particularly eye-catching. An audience from Peru said in an interview: "I am from Peru, and I am mainly looking for some service-type robotic arms that can make coffee. I think China's robotics technology is very advanced and incorporates artificial intelligence. This exhibition is very exciting .
