- Q: What are the main differences between slewing bearing and slewing bearing?
- Slewing bearing is mainly a simple turntable bearings, such as the outer ring, inner ring, steel ball, isolation block combinationSlewing bearings are actually more advanced than slewing bearings. Specifically, check with Baidu.
- Q: Luoyang bearing has been claimed to achieve maximum diameter, the maximum record of 6 meters, I would like to ask is, turntable bearings selection and calculation, need 10What are the key technical factors, especially what is most important in the process? People say that heat treatment is the most important.Luoyang bearings, the most state-owned enterprises after the restructuring of many companies that are trustworthy? What are the strengths and the best in quality?
- Compared with other bearings, slewing bearings have unique bearing characteristics, which are usually used in lifting machines, excavators, rotary tables, wind turbines, telescopes and tank turrets. Through the improvement of machining methods and the renewal of design concept, today's turntable bearings can be applied to smaller, more complex and more precise occasions. In the machine tool industry, the standard structure of turntable bearings adopts high precision grade and applies preload to eliminate clearance and reduce vibration. Bearing radial runout and diameter in the range of 1/1000 to 1/10000 inches (2.54 tan), compact structure, small size of section, and the diameter can be as small as 50 mm (ball size of this type of bearing than the traditional heavy series of slewing bearing steel ball small size). This has prompted designers to reconsider the traditional configuration of bearings. For derrick bearing radial and axial load and torque, the installation configuration using two sets of ball or roller bearings are arranged at intervals along the axis of this configuration is the 2 sets of bearings on the shaft is located remotely to obtain higher torque load capacity. However, for such configurations, it is difficult to adapt to new applications because of the space constraints and the complexity of the installation, which is the advantage of the turntable bearings.
- Q: After I change a new revolving mechanism, it still rattles. What's the matter? Urgently!
- First of all, add lubricating oil, if not, check the bearings are not damaged
- Q: For example, the text information has been searched, so far we can not find the difference between slewing bearings and slewing bearings Seeking help!
- The first turn support should be a rugged application environment, only supporting and rotating requirements, the accuracy of rotation is not high
- Q: The turntable of the excavator keeps ringing and leaking oil. When it hits butter, it does not ring on the same day and it will ring in second days
- (6) the internal seal has obvious damage: turn the gear ring, grease, check the cover, check the ring, the oil cavity, whether there is a significant reduction in oil, and whether there are broken oil seals. If there is a substantial decrease in fat, it indicates that the oil has been left out. (7) to determine the bearing cavity of the oil leakage is still the slewing ring cavity grease: different colored oils and injected into the bearing cavity, after a period of time (such as 150h) after use, such as grease bearing cavity oil has basically replaced after, according to the color of oil leakage around determine the slewing ring of oil or grease in bearing chamber. This is one of the methods used to judge whether the internal seal has failed or not. (8) to observe whether or not a normal rotary equipment: if the equipment in the rotary motion of the abnormal sound or unstable phenomenon, it may be bearing clearance is too large and uneven, resulting from the outer oil seal extrusion bearing in the rotation process of oil. (9) check the inner oil seal: the above inspection has been completed, and the elimination of problems, the problem can be concentrated in the bearing oil seal. Take out the surrounding bolts of the revolving parts, remove the tubing on the moving part, and hoist the upper frame part with a crane. Since this method requires the use of cranes and the workload of the whole process is relatively large, so this is the last step in checking and solving problems. Therefore, it is suggested that this method be adopted after all the foregoing steps have been completed and other possibilities have been eliminated. Three, treatment methods: 1, if once identified as a result of sealing problems, you need to remove the old seal, and use diesel or gasoline cleaning sealing groove, the new seal completely into the sealing groove can. It should be noted that there is a joint after sealing the ring, and it needs double tubes
- Q: Slewing bearing 011.20.250, how to choose gears?
- Slewing bearing is a bearing axial load, radial load and overturning comprehensive load, large bearing special structure function support, rotation, drive and fixed in a variety of. In general, because of its mounting hole, lubrication and sealing device, can meet the different needs of various kinds of working conditions of the host; on the other hand, the turntable bearing has the advantages of compact structure, convenient installation and convenient rotary guide, easy maintenance and other characteristics, is widely used in hoisting and conveying machinery mining, machine, construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers and other large rotary device.
- Q: How to correctly install turntable bearings?
- The inner and outer raceway of the C slewing bearing has a soft belt, which should be placed on both sides of the main load plane. That is, stagger 90 degrees with the main load area. There is a block or a "S" mark on the soft belt. It will also examine the slewing bearing and the mounting surface of the anastomosis, usually by foot inspection, if the agreement is not good, to be filled with the appropriate materials. After the turntable bearing is installed, welding operation on the support is prohibited. D, solid bolts 1, installation bolts selection: should use the specified (size, quantity, strength level, etc.) installation bolts and washers. Another note: 1) cannot use the screw bolt 2) do not use the old bolts and washers, 3) prohibit the use of openings such as elastic washers, washer 2 bolt tightening torque: choice of preload of ordinary metric bolt take 0.6-0.7 times the yield strength of bolts. Bolts recommended greater than M27 shall be hydraulically tightened and shall not exceed 85% of the yield strength. 3. Fastening bolts: slewing ring bearings should be installed without load. Caution: apply a little oil to the thread of the bolt to ensure a balance of frictional resistance. Do not use glue on the bolts.
