Improve the quality of INA plastic bearings operating protective measures

Bearing on the environment for the first time inspection should be in the light environment, it is the best astigmatism, in order to better INA bearings, was observed on the surface appearance and no crack and other anomalies. Such as cloud of mechanical wear and scratches, touch pressure in the process of bearing equipment can lead to shift, and result in poor equipment location, lead to the shape of the plastic bearing flat load and stress concentration, reduce precision and service life. When the detection of rivet head main observation is there a link between slanting, easing the welding position is not correct. The welding quality. Welding point is too small, do you have any welding or welding, solid ball card caused problems. INA bearing test need to pay special attention to the process. There are also some problems needing attention. And lubrication of the bearing is the best in the equipment downtime and implementation of the plan and added on a regular basis, at the same time, the old rid grease or via the drain the old oil out empty. Before adding fresh grease injection nozzle should be wiped clean. If there is no zerk bearing box, should open the bearing box cover or end cover, in order to remove the old grease, clean up after, supplement the same type of fresh oil. Record the activity refers to the bearing and after complete assembly of finished bearings, starting up should not jammed, binding, abrupt stop etc. Bad phenomenon. Plastic bearings rolling series of general requirements include shape dimension and tolerance grade and the public and, codes, chamfer size maximum, the radial clearance, rolling bearing ring and body hardness of materials, parts, vibration value, interchangeability and measurement method, rated load and rated life, mark, inspection rules, packaging, the residual magnetic, surface quality and cleanliness, rotational flexibility, etc. Surface quality including logo, beautiful, fine roughness etc. , are not allowed to have knocked wounded, crack, broken, black, burr, rust, wait for a phenomenon. Bearing the marks is directly related to rolling bearing surface waviness of noise, the noise is a kind of pure tone, for constant speed, its frequency is constant, with the speed of change, and the changes of its frequency. Plastic bearing need to check the oil level of lubricating oil and oily, under normal circumstances, the normal oil level should be equipment oil level Windows or mark a third - Two-thirds of the range. Oil compensating way for oil cup, the display of the oil level represents oil compensating ability, and the bearing box oil level is to meet operation requirements, oil cup CPC a lower than a quarter of its total volume filling oil may be considered. INA bearing the correct installation and maintenance is an important factor for normal operation of bearing, at the same time, must pay attention to maintain the purity of the bearing. Bearings must prevent polluted by contaminants and moisture, must have a correct installation and lubrication. In addition, the design of the bearing arrangement, the condition of the oil seal, the form of a lubricant and change cycle and special maintenance also play an important role, must be attention. When selecting new bearing, should check bearing hole of roundness and taper error, and make it conform to the prescribed standards. Check, the bearing cover and torque tighten according to regulations, dosage of cylinder table or inside diameter micrometer, the roundness and taper error should not exceed 0. 02 mm, otherwise will damage the plastic bearings and shaft neck normal fit clearance, accelerate bearing and shaft neck of wear and tear. New bearing put seat holes, each side was bearing shall be bearing surface above the 0. 03 - 0. 04mm。 This makes bearing pressure, bearing in the elastic deformation and to everyone here, not loose, and has the good performance of thermal conductivity. Bearing plate fixed tooth should be intact, or in the workplace will make shift INA bearing, lubricating oil way blocked, the oil supply disruption, burn out parts. Bearing the reverse side should be smooth level off, are not allowed to use file processing, or padded pieces of paper, so as not to affect the cooling. But in the maintenance work, often will meet with some necessary conditions, such as bearings and shaft neck fit clearance is too large, or use the old bearing, allowing padded a layer of thin copper sheet on the back of the bearing, but it must be flat and spear out of the oil hole. In addition to pay special attention to the work environment or the pollutants in the water, which is most likely to lead to import bearing rust, rust is lead to bad INA bearing installation, early wear and tear, will lead to more serious waste is a direct relationship. Therefore, it is important to pay special attention to in water to moisten of course.
