Sliding bearing sleeve is very good, the quality is very good

The most important part of the machine is the bearing sleeve, sliding bearing sleeve is very good, the quality is very good, then the bearing sets how to produce it?
1. Forging: Forging process if the overgrowth, overheating, cracking into a network of carbide and so will reduce the toughness and strength of the ring. So must always strictly control the processing temperature, the cycle of heating and forging heat dissipation conditions (such as spray cooling), especially when the larger varieties of rings after the final forging, the temperature above 700 ℃, not stacked.
2. Heat treatment: close monitoring of heat treatment equipment is an important work of the workshop.
Monitor the reliability of the equipment. On the instrument, thermocouple and other important temperature control equipment to be closely monitored to ensure accurate and reliable measurement data; the error should be replaced in a timely manner, is strictly prohibited disease operation.
3. Grinding process monitoring. Finished imported sliding bearing rings do not allow grinding burns and grinding cracks exist, especially the inner ring taper with the surface can not have burns. Ferrule if the pickling should be after the full inspection, tick out the burn products, serious burns can not be reworked or reworked should be scrapped, do not allow grinding grinding rings into the assembly process.
4. Identification management, steel storage to the ring before grinding, the process must be strictly managed, strictly distinguish between GCr15 and GCr15SiMn two different materials and products.
In order to better play the best condition of stainless steel bearings, the choice of grease on the bearing is directly related to the stable operation of the equipment. Foshan proud of the following under the Mechanical Bearing Co., Ltd. for everyone to explain the choice of stainless steel under the bearing grease must be considered from the following aspects:
1. Anti-rust performance
The rust inhibitor is preferably insoluble in water. Grease should have good adhesion, used in the bearing grease must have anti-rust effect. And can form a layer of oil in the oil film.
2. Mechanical stability
Leading to leakage. Normal operation, grease in the mechanical processing will become soft. Grease will be thrown into the bearing by the bearing. If the mechanical stability of the grease is not enough, the process of operation, will make the structure of the grease soap disintegration, resulting in oil is destroyed, and thus lose lubrication.
1. Choose an important factor in oil
Choose a kind of grease, if the wrong choice of grease all the measures to prevent the bearings is also in vain. Base oil viscosity at the operating temperature is able to provide sufficient lubrication effect is very important viscosity is mainly affected by the temperature, with the temperature rise and decreased when the temperature drop is increased. Therefore, it is necessary to know the base oil viscosity at the operating temperature. Machinery manufacturers usually use a certain kind of grease, but most of the specifications of the grease is applicable to a wide range.
2. Oil seal
During the operation of the joint bearing, the oil seal is necessary to maintain the bearings and lubricants from external contamination. Regardless of debris or moisture can not penetrate the bearing, to prevent damage to it. The correct device maintenance is to play the bearing of the longest life of the important factors. At the same time, it is necessary to pay attention to the cleanliness of the bearing, the correctness of the bearing selection and the selection of appropriate equipment and maintenance tools. In addition, the bearings must be protected against contamination by contaminants and moisture and are guaranteed to be properly installed and lubricated. So the design of the bearing arrangement, the status of oil seals, the type of lubricant and lubrication cycle, and even special maintenance are playing the same and important role.
3. Classification of oils and fats
Grease consistency and lubrication capacity is affected by the operating temperature of a temperature operation of the joint bearing must choose the same temperature under the correct consistency and good lubrication effect of grease. Grease is made in different operating temperature range can be divided into low temperature, medium temperature and high temperature grease. At the same time, mainly according to the temperature and working conditions to distinguish: grease can be classified according to its allowable working temperature. There are a class of oils called anti-extrusion or resistance to extrusion and add molybdenum disulfide, while adding additives to enhance the strength of the lubricating oil film.
4. Mix grease
If you mix two incompatible oils and fats, never mix compatible oil. Usually its consistency will become soft, and finally may be easily lost due to grease and cause damage to the bearing. If you do not know what kind of grease used in the original bearing, you must first completely remove the old grease inside and outside the bearing before adding new grease.
Check the surface before cleaning the machine, and then remove the parts around the SKF bearings. Seal is a very fragile part, in the need to carefully disassemble, do not over-force, and then carefully check the oil seal and its surrounding parts, if there have been bad symptoms, be sure to replace the bad oil seal will lead to the bearing Damage and strict equipment downtime.
Check the lubricant, stained with little lubricant between the two fingers, if there is contaminant, can feel out, or in the back of the hand coated with a thin layer of lubricant, and then sealed light inspection.
Replace the lubricant, oil lubricated bearings in the diarrhea in addition to the old oil, then pour fresh oil and let the machine rotate at a low speed for a few minutes. As far as possible so that the oil to collect residual pollutants, and then diarrhea in addition to these oils, oil in the best before the first filter.
Grease-lubricated bearings used in the replacement of the grease should be avoided with a cotton material angle to any part of the bearing, because these residual fibers may wedge between the rolling parts and cause damage, especially Is the application of small bearings should pay attention.
Cover exposed bearings, check SKF bearings, do not let the bearing exposed to contaminants or moisture environment. If the work is interrupted, should be oil paper plastic film or similar material over the machine. If you do not have to disassemble and may perform the inspection of the case of cleaning unmasked bearings, to apply the brush with a solvent to wash the oil solvent, and then dry with a lint-free fabric or compressed air dry (careful not to let Bearing assembly starts to rotate).
Do not clean the seal or dust-proof bearings; only wipe the external surface can be. If the bearing is damaged, it is necessary to replace it. It is much more economical to replace the joint bearing in the regular downtime than the sudden loss of the selected seal due to the damage.
