陶瓷轴承 的概念：大家都知道在 工程陶瓷 产品的开发应用中，陶瓷球轴承是工程陶瓷在工业领域应用的典型范例，受到广大陶瓷结构件轴承厂家的重视，在高速 精密轴承 中，应用最多的是混合陶瓷球轴承，即 滚动体 使用热压 Si3N4 陶瓷球，轴承圈为钢圈或者44C。 First of all, let's first understand the concept of ceramic bearings : Everyone knows that in the development and application of engineering ceramic products, ceramic ball bearings are a typical example of the application of engineering ceramics in the industrial field. Among the bearings , the most widely used are hybrid ceramic ball bearings, that is, the rolling elements use hot-pressed Si3N4 ceramic balls, and the bearing rings are steel rings or 44C. This kind of bearing has a high degree of standardization, small changes to the structure of the machine tool, easy maintenance, and is especially suitable for high-speed operation. 电主轴 ，具有高速、高刚度、大功率、长寿命等优点。 The assembled high-speed electric spindle has the advantages of high speed, high rigidity, high power and long life. 轴承钢 /不锈钢+陶瓷球+ PA66 /不锈钢保持器+2RS/ZZ2.高温油脂，3.采用陶瓷球轴承和普通轴承相比的优势. 1. Bearing configuration: inner / outer ring bearing steel / stainless steel + ceramic ball + PA66 / stainless steel retainer + 2RS / ZZ2.High temperature grease, 3.Advantages of using ceramic ball bearings compared with ordinary bearings.
微型陶瓷轴承 的范围： 微型陶瓷轴承 是指外径小于25mm的轴承，这些轴承中2mm及以下的轴承是用途特别广泛，不过由于机器设备和装配的难度很多一般工厂的设备还达不到生产要求。 Secondly, Yuwei let everyone know the scope of miniature ceramic bearings : miniature ceramic bearings refer to bearings with an outer diameter of less than 25mm. Among these bearings, bearings with a diameter of 2mm or less are particularly versatile, but due to the difficulties of machinery and equipment and assembly, many ordinary factories The equipment does not meet the production requirements.
陶瓷轴承生产厂家 ，我们一直在寻找这方面技术的突破。 As an industry-leading manufacturer of miniature ceramic bearings , we have been looking for technological breakthroughs in this area. By chance, I met a customer in Xi'an specializing in the production of motors. This customer is a member of the China Electromechanical Association and a listed manufacturer of national military motor products. They mainly produce high-precision motors and motors, and have accumulated rich R & D and production for many years. Manufacturing experience. At the same time, they have also cooperated with many domestic research institutions and colleges, and have made significant contributions to the fields of national aerospace, petroleum exploration, and robotics.
What this customer needs to do is an open type coverless bearing with a size of 2 * 5 * 2.5mm. They want to use it on a miniature high-speed motor. The specific requirements are as follows:
1. Need high temperature resistance of about 700 degrees, 2. To achieve a speed of 55,000 rpm; 3. Life expectancy of more than 190 days; 4. Noise to 31 decibels.
Note: This customer has used imported bearings from a well-known foreign brand, but the internal cage of the bearing was severely deformed in less than a month, and other non-deformed bearings have abnormal sounds.
御微轴承 给了客户如下的建议： Thirdly, according to customer requirements, Yuwei Bearing gave customers the following suggestions:
氮化硅陶瓷轴承 。 (1) Judging from the first requirement of this bearing, Yuwei Technology Department recommends that customers use silicon nitride ceramic bearings .
(2) This is MR52 bearing in terms of size, but the customer needs to make it open without cover. If it is made of bearing steel or stainless steel, it will be more troublesome. There is no difficulty in selecting ceramic bearings, because ceramic bearings are manufactured by sintered blanks, so it is not a big problem to produce bearings with open caps in this size.
(3) Because it is difficult to produce ceramic bearings with an inner diameter of 2mm, it is even more difficult to add silicon nitride. For light ferrules, a small amount of scraps will be produced by accident. In addition, it will not be easy to assemble during assembly. Our workers need the cooperation of a magnifying glass to assemble these bearings.
After the tireless efforts of Yuwei technicians and workers, a bearing sample with an inner diameter of 2mm was finally made. After receiving the sample test, the customer said that the effect was very good, let us mass produce. 高品质陶瓷轴承生产厂家 ，御微严格按照客户要求，不会放过任何一个技术黑洞。 Yuwei Sales tells customers about the production process of Yuwei. As a manufacturer of high-quality ceramic bearings , Yuwei strictly follows the customer's requirements and will not let go of any technical black hole. It is not easy for customers to admire them. Customers are amazed by Yuwei's spirit of overcoming difficulties. After three months, the customer's order came again, and introduced another counterpart customer for Yuwei Company.
