When grinding wheel bearing installation and dismantling

Actually grinding wheel bearing is a special kind of cutting tool, the speed is very fast, when used in order to better use of the grinding wheel bearing we must pay attention to its installation and remove some of the method and the matters needing attention. Wheel bearing installation method 1, steps the clamping flange plate grinding wheel: larger aperture used parallel grinding wheel, grinding wheel with nut and screw clamp first between the two flanges, and then loaded on the outside of the grinding wheel spindle vertebral body, with a nut fastening. 2, plane clamping wheel flange plate: not too big diameter used parallel grinding wheel and cup wheel, the grinding wheel with plane flange and gasket with nut directly clamped on the long axis of the grinding wheel spindle or pick up. 3, connect a long axis clamping: small diameter used ( 20 mm below) The grinding wheel. 4, sulfur adhesive clamping is suitable for the cylinder wheel. When the erection and dismantling of grinding wheel bearing should be paid attention to the following: 1, grinding wheel bearing before installation, should check the grinding wheel crack. Commonly used method is to hang wheel, with wooden handle gently tap on a grinding wheel profile, such as the sound of a ringing, grinding wheel, no crack, such as the sound of a 'dumb', then grinding wheel has a crack. 2, grinding wheel bearing inner hole and extension shaft, flange, etc. , shall have the appropriate clearance, to avoid heat expansion and make the wheel up when grinding crack. 3, when using the clamping flange plate grinding wheel, the diameter of the two flanges must be equal, they should be no less than a third of the grinding wheel diameter, the size of the flange end face on the center of the part to dig deeply within 2 ~ 3 mm ring groove, make its only a circle to the outer ring surface contact with the grinding wheel, in order to make sure the clamping stable, at the same time, contact with the grinding wheel flange plate face must be straight. 4, between the flanges, gaskets and grinding wheel face, should be put on the cardboard, oil resistant rubber liner made of elastic material, such as the compression flange and gasket stress uniform distribution, so as not to damage the grinding wheel. The thickness of the liner can be 0. Between 5 ~ 1 mm, its diameter should be slightly larger than the diameter of the flange or washer. 5, the fastening flange, nut cannot twist too tight, otherwise the grinding wheel will be broken. When using a few screw flange, should press diagonal sequence points several times to gradually tighten the screws. Tighten the screws, can only use standard wrench, and are not allowed to use the method of extension wrench or beat up tight. 6, the grinding wheel flange when loaded on the grinding machine spindle, must take the taper hole of flange plate and grinding machine spindle cone wipe very clean, to ensure the concentricity of the grinding wheel and spindle. 7 after balance, the new grinding wheel loaded on the grinding machine for the first time, must have a shield under the condition of idling 1 ~ 3 min, at this moment the operator must stand in the side of the grinding wheel, in case of an accident. 【 Warm prompt. 【 The bearing network] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent our views to its approval or responsibility for their authenticity.
