Explore the non-standard bearing maintenance RunHua method

Explore the non-standard bearing maintenance RunHua method source: bearing | last updated: - 2020 10 - 14 to explore non-standard bearing maintenance RunHua methods according to the suitable position and application of standard specifications, according to the natural environment standard choice precision and adaptation of non-standard bearings, bearing life and reliability is the premise. Position of use: apply to undertake non-standard bearing dominated the axial and radial axial and the coordination of the axial load, generally USES two non-standard bearings, its key parts should be in the car before and after the left and right wheels, active circular gear shaft, transfer case, speed reducer drive system such as position. Allows the speed ratio, appropriate, RunHua good natural environment, the limit allowed speed ratio is bearing limit speed than 0. 3 - 0. 5 times. Usually in normal cases, the limit speed ratio is 0. 2 times the most suitable. Permissible Angle: non-standard bearings are usually not allowed on the axle housing with dip Angle, Angle, if any, shall not exceed 2 'biggest. All allow temperature: under normal load, under the standard of lubricating wet, high temperature resistance and enough normal bearing can be in - 30 c - 150 c operation. Non-standard bearing grease selection properly, non-standard bearing failure too early, accounting for 36%. General cannot meet the needs of all kinds of bearing with grease, and can only use one or more general to consider all the use of the bearing grease, this creates great difficulties for general purpose grease, because gm grease has gone far beyond the general benefits of grease. Use the operation condition of the bearing is varied, the appropriate RunHua is consistent regulation the operation condition of the bearing and lubricating oils. Even under the most extreme working standard, and ensure a steady bearing, bearing grease running smoothly and with higher reliability. Can prevent air pollutants into the bearing grease, cache the impact of the bearing and the ability to resist corrosion. Choose the appropriate lubricating oil used in the specific application is the basic standard for bearing a long lifespan. Appropriate choice of lubricant standard include: types and specifications of non-standard bearing, temperature, speed, load and expected lifespan, as well as the lubrication cycle. In the input quantity decides the degree of mutual cooperation and at the same time, the initial axial bearing clearance decreases in the input process. Therefore, before the installation must first accurate measurement of non-standard bearing the axial clearance. Whole process for accurately measuring bearing feed axis to the lateral clearance, until meet the reduce a small amount of the axial clearance and ideal transition fit. Due to temperature RunHua, speed ratio, load and natural environment factors, such as the value table only said about temperature range. To effective RunHua roll bearing, the fatigue life and wear and tear, damage, heat, vibration, etc all have important harm, all normal RunHua, bearing cannot work normally. Analyzes the damage reasons of non-standard bearings, shows that 40% of bearing damage associated with RunHua adverse. Therefore, the high quality RunHua non-standard bearings is reasonable countermeasures to reduce bearing wear and damage. In addition, bearing RunHua with sealing, heat removal, rust and reduce the impact of various effects.
