Deep groove ball bearing limit speed of the step is the maintenance?

When the deep groove ball bearings in 0. 1 c load working conditions for the roll body and raceway contact surface between the contact stress increases, the bearing operating temperature, smooth agent performance is relatively worse, therefore, the limit of the deep groove ball bearing speed will decrease accordingly. About the range of C / = 10, because of the limit speed drop is very small, so it can not be considered, namely the f1 = 1. Centripetal bearing about accept joint load function, because the number of the roll body to accept the load increasing, the friction resistance increases, higher calorific value, smooth and cooling conditions, and the force applied to keep the rack also increases, thus, bearing co. , LTD. , zhejiang province technical claims related personnel must be based on the size of the bearing type and load Angle, the deep groove ball bearing limit speed multiplied by the coefficient of a decline in f2. If the selected speed limit speed cannot be satisfied with requirements of the bearing, can choose some improvement progress, technical measures to reach satisfactory requirements. Such as progress bearing level public service; Appropriate increase clearance; Use special materials and the structure of the improved cage; Change the way smooth, if choose oil and gas, oil mist and eruption is smooth; An improved cooling condition, etc. A smooth, deep groove ball bearing protection should keep smooth in the operation of the test method of oil unobstructed, regularly check the sealing condition of seal to replace the damaged seal in time. And to monitor the running status from noise. Smooth agent, the three aspects, such as temperature monitoring. Because when normal operation should be a steady hum, abnormal when handled in time, normal smooth agent is clear and clean, if smooth agent has become dirty, there will be wear particles or contaminants, at higher temperatures, the job will appear abnormal. 2, deep groove ball bearing is smooth to protect the concrete steps of 1, the importance of smooth smooth technology attaches great importance to the deep groove ball bearings. Smooth and able to take advantage of the roll surface of relative movement between the oil film will separated from each other, not as rough point contact lead to excessive wear and failure, also can guarantee the designated life remained stable during the period of performance test and rotation accuracy. 2, smooth category into fat oil and smooth smooth, fat smooth smooth facilities is the advantage of a brief, smooth and fat is not easy to leak, have certain waterproof, gas and other impurities into the ability, thus generally widely used grease is smooth. Such as overloading, high speed, high temperature working condition of oil is smooth. 3, smooth the use of the fat in moderation. Best to fill space bearing and deep groove ball bearing shell of 1/3 and 1/2 shall prevail, if add too much fat, because of mixing and heat, will worsen fatty metamorphosis or chin. High speed should be padding to only one-third or less. When the speed is very low, in order to avoid external foreign body of science into the deep groove ball bearings can full housing space. 4, bearing safekeeping is strict with its storage and preservation of the environment, such as temperature, humidity, etc. To do before delivery are coated with anti-rust oil, room temperature should be controlled in 0 25 ℃, relative humidity should be kept at 45% 60%.
