Bearing cleanliness is a quality assessment indicators bearing must be ensured by cleaning quality of the production process. Improving the quality of cleaning, which requires strict management, but also need to apply advanced cleaning technology to meet the cleaning requirements of the product. Currently bearing industry, bearing cleaning manner mainly gasoline or kerosene as cleaning medium spray cleaning. This approach is not only costly, labor-intensive, low productivity, and poor security, and more importantly, this cleaning method is difficult to achieve the required cleanliness standard bearings. Seek safer, more economical, more efficient cleaning method for cleaning the finished bearing great significance.
Conventional cleaning methods bearing parts are brushing, immersion, spray cleaning or high pressure spray and other factors related to the main cleaning agent (use ultrasonic cleaning) and the use of performance requirements, the structure of the workpiece, the size, weight and material as well as the batch size, clean workplace occupational safety and environmental requirements. Ultrasonic cleaning cleaning as a good new technology, has been more and more attention in the bearing industry.
Cleanliness of rolling bearing vibration it, my voice, different tones and life have a great impact. Especially in small, low voice sound deep groove ball bearing production, improve cleanliness is the solution to one of the key bearing my voice, abnormal sound, so the cleaning process is a very important part. Bearing cleaning in the production process is generally divided into two steps namely in the parts prior to assembly (rings, balls, retainers, etc.) finished cleaning and riveting assembly after cleaning.
Third, we must determine the cleaning effect of the number of: cleaning media (cleaner), cleaning processes and cleaning devices.
First, ultrasonic cleaning agents
Ultrasonic cleaning agent Description: ultrasonic cleaners having to various parts of the oil thorough cleaning function. A unique role in the destruction of the chemical structure of various molecules grease, so as to quickly and thoroughly remove heavy grease purposes. Mechanism of ultrasonic cleaning: because cavitation bubbles generated when the powerful blast shattered, part of the dirt layer is peeled shock wave, dispersion, emulsification, off. Because cavitation bubbles generated by the gap and voids and surface dirt layer formed by an impact between the penetration, since such small bubbles and the sound pressure synchronization expansion, contraction, peeling-like repeated physical forces acting on the dirt floor, dirt layer a layer is peeled off, the bubble continues to penetrate inside until the dirt layer is completely stripped. This is a secondary effect of cavitation. Ultrasonic cleaning liquid cleaning ultrasonic vibration impact on the dirt. Ultrasonic chemical cleaning agent for accelerating the process of dissolution of dirt, chemical and physical forces, combined forces to accelerate the cleaning process.
Instructions 1, cleaning method: ultrasonic 2, cleaning method: Usually 5 - 10% according to dope watered slotted continued use liquid dosage 1--3%, temperature 25--60 ℃, recommended temperature 40--60 ℃, ultrasonic cleaning time 1--30min, after washed with water, drying can be. Specific cleaning process according to the actual situation of production, developed by professional engineers behind cleaning solution can be used.
