Jiaxing bearing small make up for you to share bearing vibration damage of several major problems should be paid attention to

There is rotational, have HRB bearing ( ) Jiaxing bearing the author to share for you bearing vibration damage of several major problems should be paid attention to. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. Bearing vibration in production in general, the rolling bearing itself does not produce noise. Often feel 'bearing noise' is in fact the bearing directly or indirectly, with the surrounding structure vibration sound effects. This is why many times the noise can be seen as involving the whole bearing vibration problem of application. （ 1) Due to loading quantity change of vibration roller: when a load on a bearing radial load, the number of rolling element bearing load will be a slight change in the running, this caused the load in the direction of migration. The resulting vibration is inevitable, but can be by axial preload to ease, loading in all rolling body ( Do not apply to the cylindrical roller bearing) 。 （ 2) Partial damage: due to the operation or installation errors, a small number of bearing raceway and rolling element may be damaged. In the running, rolled the damaged bearing parts will produce a particular vibration frequency. Vibration frequency analysis can identify the damaged bearing parts. This principle has been used in the condition monitoring equipment, used to detect damage of bearing condition. If you want to calculate the bearing frequency, please see the application 'bearing frequency. （ 3) The precision of the related parts: in the bearing ring and the bearing seat or under the condition of close cooperation between the shaft, bearing ring with adjacent components are likely to match the shape and deformation. If there is a deformation, can produce vibration in the operation. （ 4) Pollutants: if run in environmental pollution, impurities may enter the bearing and roller compaction. Vibrations depends on the number of impurity particles crushed, size, and composition won't produce the frequency of the typical form, but you can hear a disturbing noise. Cause noise of rolling bearings is more complex, one is the bearing inner and outer surface wear. Due to the wear and tear, damage to the bearings and shell, bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound. When the bearing fatigue, its surface metal flake, also can produce sound make bearing radial clearance increases. In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise. Bearing wear loose after kuang, maintains a looseness damage, also can produce sound. Bearing used in daily life, need careful attention to its use, let's see if we need to pay attention to the nine big matters. 1, combine the riveting pieces such as the moving blade assembly, rivet are generally made of cold extrusion in riveting right should not be heating, such as heating will reduce the strength of the material. Forming punch riveting after application of the heavy willow, to strengthen the robustness of blades and knife bar. 2, the vulnerable parts, especially the pin shaft, tabletting, cover, cushion iron does not replace to add butter in maintenance and repair, such as long time use of wear and tear to the limit of components can cause other mechanical life cut short. 3, no balancing machine axle repair in the repair of various axial balance, can be in one end of the shaft to a thrust bearing, holding on the lathe three jaw, on the other side can use top to resist, such as lathe, available center frame clamp at the other end mounted on the shaft SKF bearing, balance correction. But in weight, with bolt tightening, try not to weight in welding way. 4, in the maintenance of bearing material type is various, not easy to purchase, available old axle processing at present our country most of axial is 45 # carbon steel guitar is given priority to, such as quenching and tempering, in the case of bad conditions, available oxygen, soil furnace heat required parts to red found put the salt water, according to demand. 5, as much as possible in the set of parts machining parts in a set of holes in the tank for harvester refueling is very difficult and the place difficult oiling every available butter and heavy oil, except the nylon sleeve. All nylon sleeve parts, it is best not to replace with cast iron, copper, aluminum, because nylon set under certain impact without deformation. 6 key and keyway on the shaft, pulley, and repair shall ensure that the size is not in advance, could not increase the size of the key, otherwise it will affect the strength of the shaft, shaft keyway available welding filler repair welding in the opposite direction to the old key a keyway milling, pulley keyway on the set of available ( Transition fit) After way, with good, with countersunk screw tapping to tighten the plug button in the set of seam. 7, harvester maintenance of hydraulic parts distributor and reducing valve, air flushing with air pump to the pipe pressure, the hydraulic oil secondary load should be filter, exhaust, hydraulic maintenance is mainly seal assembly, and the seals had better off after change new. 24-hour customer service hotline: if you are more interested in jiaxing bearing the author introduced the industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - - - - - - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
