The page and the bearing assembly method and installation technology requirements

The page and the bearing assembly method and installation technology requirements of the bud and the bearing assembly method: assembly, bud when the bearing is the most basic requirement is that the axial force exerted directly applied to the installation of the bearing ring end face ( When installed on the shaft, the axial force exerted is straight connection effect, circle, when installed on the hole, the force applied directly on the outer ring) 。 Try not to impact roller. Assembly method is a hammer, pressure machine assembly method, thermal assembling method, freezing method for assembling, etc. 1, with a hammer peening method mat tongbang then hammer soft material such as the bud of bearing inner ring or outer ring. Be careful not to let foreign bodies fall into such as at the end of the copper bearing raceway, don't directly hit with a hammer or a punch bearing inner ring and outer ring, so as not to affect the page the page and the matching precision of bearing or damage to the bearings. 2, for interference tolerance a big beautiful page and bearing, and can be through the screw press or hydraulic press assembly. Before the pressure into the shaft and the bud and the bearing is flat, and apply a little oil, pressure velocity shoulds not be too fast, the page should be quickly remove the pressure after the bearing in position, so as not to damage the bud is the bearing or shaft. 3, hot pack is the first page and the bearing in oil heated to 80 ° C - 100 ° C, make beautiful bud again after the bearing inner hole expansion is set in the shaft, prevent damage of the bearing axis and the bud. For belt and bearing, dust cover and seal of the bud is inside the bearing grease filling the beauty of the bud is not suitable for hot pack. The bud and the technical requirement of bearing installation 1, with the beauty of the code page and bearing end shall be installed along the direction of visible and so that to be the time when replacement model check. 2, the steps of the journal or shell hole arc radius should be less than the radius of the circular arc of the corresponding to the bearing. 3, bearing installed on the shaft and bearing hole, should not be skewed. 4, in the coaxial two bearings, there must be a bearing with axial thermal produced when axis movement. 5, U. S. page and bearing assembly, must be strictly prevent dust foreign body into the bearing. 6, after assembly, the bearing should be flexible rotation, low noise, working temperature is generally not more than 65 ° C.
