We need to understand the entire mechanical equipment (composition: drive device, speed change device, etc.), and then inspect the degree of friction between the machined surface of each part and the bolt. The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, which can be designed to match the raceway surface according to the application. With this outer ring, the rollers can roll directly on the raceway and can withstand heavier loads and shock loads. 2. During mechanical installation, dry oil should be applied to the fixed contact surface, and thin oil should be applied to the movable surface. In particular, after the bearing is installed, the outer ring must be inclined to apply the bearing lubricant to reduce or avoid friction and wear). 3. The lubricant coating of the bearing is also very particular. When grease is applied, all the roller surfaces are covered. After coating, the position of the outer ring is restored. It is also necessary to cover the dust with plastic film. 4. Pay attention to cleaning the bearing in daily use, first put the bearing in the oil, then use a brush to brush off the dirt on the bearing surface, then properly heat the oil, and then clean the balls and holes inside the bearing in detail. . Then everyone should have some understanding of this knowledge! If you know of other better ways to extend the life of bolt roller bearings, please report to the staff of the needle roller bearing manufacturer in time, and we will listen to your suggestions carefully. and make corresponding adjustments. The improper way of the bolt roller bearing manufacturer can also cause the roller bearing to heat up. Lubrication can reduce the wear of parts in motion, ensure the accuracy of the press, and reduce energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication, etc. The main carrier in the composite roller bearing mainly bears the vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full complement roller bearing, it can also be used alone as a one-way bearing. The regular inspection of the oil of the bolted roller bearing replaces the oil replenishment method, removes a small amount of oil, fresh oil samples and more potential enterprises can be used for oil testing to ensure qualified crude oil. If the sample is cloudy and then mixed with water, it can be said that the emulsified oil has a darker color on the bearing. If the sample or process thickens, it will indicate that the crude oil has already been completely replaced by carbonization. old oil. The oil should be washed with fresh oil if it will. The oil change should ensure that the new oil is replaced, the same old car series, and oil is added to meet the requirements. Bolt roller bearings, oil bath air intake system, if the water temperature is in the 60°C (40°F) section, the oil is not damaged by the environment, and the oil can be replaced many times over the years. If the oil temperature is 60-00°C (40-20°F), change the oil five times a year. If the water temperature is 00-20°C (20-250°F), then change the oil several times a month. If the water temperature is around 20°C (250°F), then change the oil several times a week. The bolted roller bearings have no leaking storage warehouse storage parts, prevent sun exposure, indoor environment retail, but there can be no dust. Ventilation and temperature control facilities should be set up. The warehouse should be kept dry, the air humidity should be below 80%, the room temperature should be 25 degrees, and the temperature change at night should not be so great. If the temperature is too low, it is easy to crack the crystal of the rust remover, causing some exposed metals to corrode, heat-resistant, and the rust inhibitor is easy to damage (volatile) or deteriorate, and the temperature difference between day and night moisture is easy to corrode and cause initial Condensed on the surface of the bearing. In winter, the bearing should not be placed near the heating part.
