Even parsing the pump shaft bearing the installation procedure of bearing and taper roller bearing must be conducted in a dry, clean environment conditions. Before installation should carefully check the shaft and the shell surface, convex shoulder of end face and groove and the connection surface machining quality. All cooperate with the surface of the connection must be carefully cleaned and remove burrs, must remove all traces of sand casting raw surface. Bearing should be taken before installation with petrol or kerosene wash clean, dry after use, and to ensure good lubrication, bearing generally use grease, oil lubrication may be adopted. Using grease lubrication, should choose without impurities, oxidation, rust and extreme pressure properties such as high quality grease. Grease filling quantity for bearings and bearing box - 30% of the volume 60%, unfavorable and overmuch. With sealing structure of double row tapered roller bearing and water pump shaft bearing has good filling grease, users can directly use, shall not be clean. Bearing installation, it must be in the ring width on the circumference of a circle of equal pressure, to press the ring into, can not use ð ¨ +  top tools directly on bearing face, in order to avoid damage In the case of a small amount of interference, but at room temperature with the sleeve pin bearing ring end face, with a ð ¨ +  head banging on sleeve, through the sleeve ring is balanced If large quantities of installation, can use hydraulic press. Fashionable, should guarantee the outer end face and the shell shoulder end face, inner ring end face and the shaft shoulder end face pressure, there is no gap. When large amounts of interference, can use oil bath heating or sensor heating method to install the bearing, the heating temperature range of 80 ℃ - More than 120 ℃, 100 ℃, the highest can't. At the same time, nut or other appropriate method is applied to tighten the bearing, in order to prevent the bearing width after cooling contraction and make the clearance between the ring and the shaft shoulder. Single row tapered roller bearing installed last should undertake clearance adjustment. Clearance value should be used according to different conditions and cooperate with the amount of interference and specify the size. When necessary, shall be tested to determine. Double row tapered roller bearing and water pump shaft bearing in have been adjusted when delivery from factory clearance, installation time don't have to adjust. Bearing test should rotate after installation, the first axis of rotation or bearing box with the hand, without exception, with a power of no load, low speed, then according to the condition of operation gradually increase the speed and load, and detection noise, vibration and temperature rise, found abnormal, should stop and check. Running test normal rear deliverables. Jiaxing bearing co. , LTD. Is a ( ) A specialized production automobile water pump bearings, shaft bearings, water pump bearings professional manufacturers, the company strictly in accordance with the quality of customer requirements and time to provide error-free, with cost-effective products and services, welcome to inquire. A: on the water pump bearing can't work, how to repair? Next article: China bearing industry development trend of good relevant tags: shaft bearing, axis bearing, axis related news even bearing fault even how to recognize the pump shaft bearing radial clearance original water pump bearing vest in non-standard axle even even bearing shaft bearings is to simplify the bearing of double bearing even auto water pump shaft bearing is an important part related products
