Power operation, from the no-load low-speed start slowly and progress to the conditions determined by the rated operation. Test run to check the matters, whether there is abnormal sound, fag bearing temperature changes, smooth agents leaked or discoloration. If abnormal operation should be stopped, check the mechanical, if necessary, to remove the bearing check.
After the forklift bearing device, in order to check whether the device should stop running the check. Small mechanical hand rotation, to confirm the ability to rotate smoothly. Inspection items nick, indentation, which are dysfunctional, bad device, the device processing bad moment instability, the clearance is too small, the device error, and seal friction sparked torque and so on. If nothing abnormal was able to start power operation.
Large machinery can not be manually rotated so cut off the power immediately after the no-load start, idle machinery, check for vibration, noise, ability to have contact with rotating parts, etc., to confirm that no abnormality, the power operation.
The bearing of the rotating sound checked with a stethoscope and other strong metal noise, abnormal sound, irregular sounds and other states of exception. Smooth bad its cause, the poor accuracy of shaft or bearing, fag bearing damage, such as dust and debris.
Medium and large ball bearings, fat smooth, especially in the winter, low temperature and other environmental conditions, there will be grinding roll sound. Ordinary, even if the onset of grinding roll tone, the bearing temperature will not rise, do not affect the fatigue life of smooth fat life, normal use.
Forklift bearing temperature, bearing the external temperature of the ordinary can be based on speculation. Application hole directly measure the temperature of the bearing outer ring is even more accurate. Bearing temperature is gradually increased from a running start, usually 1 to 2 hours after temperature stabilization. If the forklift bearing device is bad, the temperature will soar, showing unusually high temperatures. Its cause, such as smooth agent too much, fag bearing clearance is too small, adverse installations, seal installation friction. A place of high-speed rotation, the bearing structure, smooth the way, the wrong choice of its cause.
Grease lubrication method is simple and easy roll replacement and convenient features, a wide range of applications. Should be based on the rolling mill bearing temperature, speed, rolling force and sealed waterproof performance, the impact shock size for fat method to choose the appropriate grease. Opt for the high temperature, viscosity, extreme pressure grease of good performance and high resistance to water washout performance of the regular factory. The working characteristics of rolling mill bearings should be selected additives containing ep 2 #, 3 #, lithium grease or polyurea fat.
Although the high-performance grease procurement costs, but with less, forklift bearing life, the total cost is to reduce. Other to fill grease in moderation and fill the place, not mix different brands of grease, mill bearing surface is always in the film normal state.
Initial grease fill fag bearing internal space fill to fill a sufficient amount of grease for each bearing of the vertical roll or oblique roll upper and lower lid. Each roll to check the grease hardening black, is the impurity contamination of whether the oxidation of the emulsion. If you continue to use the above situation should be thoroughly replace the grease and check the seals and seal the structure to be replaced or improved; if the situation is still good to add new fat.
Oil lubrication bearing lubrication and bearing from time to time in the work which the compressed air drops with a lubricant into the bearing internal lubricant to stay within the forklift bearings, air bearings running in the heat away, while preventing external impurities in water vapor immersed within the fag bearing. The oil is atomized and does not pollute the environment.
