Bearing cleanliness is an important assessment index of bearing quality, which must be guaranteed by the cleaning quality in the production process. The improvement of cleaning quality requires not only strict production management, but also the application of advanced cleaning technology to meet the cleaning requirements of products. At present, in the bearing industry, the main way of bearing cleaning is spray cleaning with gasoline or kerosene as the cleaning medium. This method not only has high cost, high labor intensity, low production efficiency, but also poor safety. More importantly, this cleaning method is difficult to meet the standard of bearing cleanliness requirements. Seeking a safer, more economical and more efficient cleaning method is of great significance to the cleaning of bearing finished products.

轴承零件的常规清洗方法有刷洗、浸洗、喷淋清洗或高压喷洗等，相关的因素主要是有清洗液的性能及使用要求、工件的结构、尺寸、重量和材料以及批量大小、清洗作业场所的劳动及要求等。但对清洁度要求甚高的轴承而言，这些清洗方法的效果都不够理想，而超声波清洗作为一种优良的新工艺，已在轴承行业越来越得到重视。

The conventional cleaning methods of bearing parts include brushing, immersion, spray cleaning or high-pressure spray cleaning. The relevant factors are mainly the performance and use requirements of cleaning fluid, the structure, size, weight, material and batch size of workpiece, labor safety and environmental protection requirements of cleaning workplace, etc. However, for bearings with high cleanliness requirements, the effect of these cleaning methods is not ideal, and ultrasonic cleaning, as an excellent new process, has been paid more and more attention in the bearing industry.

滚动轴承的清洁度对它的振动、嗓声、异音和使用寿命有很大影响。尤其在小型低嗓声深沟球轴承的生产中，提高清洁度是轴承嗓声、异音的关键之一，所以清洗工序是十分重要的一环。轴承清洗在生产过程中一般分为两步即在装配前的零件(套圈、钢球、保持器等)清洗和装配铆合后的成品清洗。 决定清洗效果的三要素：清洗介质(清洗液)、清洗工艺和清洗装置。

The cleanliness of rolling bearing has a great influence on its vibration, noise, abnormal sound and service life. Especially in the production of small low noise deep groove ball bearings, improving cleanliness is one of the keys to solve the bearing noise and abnormal sound, so the cleaning process is a very important link. Bearing cleaning is generally divided into two steps in the production process, that is, the cleaning of parts (ferrule, steel ball, retainer, etc.) before assembly and the cleaning of finished products after assembly riveting. Three factors that determine the cleaning effect: cleaning medium (cleaning solution), cleaning process and cleaning device.

轴承成品清洗工艺和清洗装置，基于清洗系统设计基础和实际需求,确定了以超声波清洗和喷淋清洗为清洗方式的轴承成品典型清洗工艺流程:退磁→初喷淋→超声波清洗→精喷淋→风刀吹净→二次吹净→热风烘干。

Based on the design basis and actual requirements of the cleaning system, the typical cleaning process of bearing finished products by ultrasonic cleaning and spray cleaning is determined: demagnetization → primary spraying → ultrasonic cleaning → fine spraying → air knife blowing → secondary blowing → hot air drying.

根据清洗工艺流程,清洗装置的机械结构设计采用机械臂手由PLC的控制系统,实现了装置的手动及全自动控制，不需要随轴承大小改变作调整的定位装置,实现准确定位。在超声清洗、精喷淋和二次吹净三个主要的清洗工位,设计了旋转机构,保证了清洗的充分性。

According to the cleaning process, the mechanical structure design of the cleaning device adopts the manipulator and the PLC control system to realize the manual and full-automatic control of the device. There is no need to adjust the positioning device with the change of bearing size to realize accurate positioning. In the three main cleaning stations of ultrasonic cleaning, fine spraying and secondary blowing, a rotating mechanism is designed to ensure the sufficiency of cleaning.
