Inclined rail special machine for servo gate valve Brand special machine for servo gate valve's main shaft is a hollow stepped shaft. The inner hole of the spindle is used to pass through the long bar material and the steel bar when the center is removed, and can also be used to pass through the mechanism of the pneumatic, electric and hydraulic clamping device. The taper hole at the front end of the spindle is in metric 90mm for mounting the center sleeve and the front center. Sometimes the mandrel can also be installed, using the friction of the cone match to directly drive the mandrel and the workpiece to rotate. The taper hole at the rear end of the spindle is the process hole.

special machine for servo gate valve special machine for servo gate valve bearing clearance adjustment method is as follows: First loosen the locking screw on the front end adjusting nut, and then tighten the adjusting nut, then the inner ring of model 3182124k moves to the right relative to the spindle cone, because the inner ring of the bearing is very thin, and the inner hole is the same as the spindle cone, with a taper of 112, so the inner ring is radial elastic expansion while moving axially. To adjust the radial clearance of the bearing or the degree of pre-tightening, after proper adjustment, tighten the locking screw of the adjustment nut.

The tolerance of radial runout and glaze runout of the spindle is 0 0imrrJ. special machine for servo gate valve The radial runout of the spindle affects the roundness and concentricity of the machined surface. Axial runout affects the flatness and pitch accuracy of the machined end face. Under normal circumstances, when the runout of the main shaft exceeds the allowable value, the main shaft runout quantifier can be adjusted to the allowable value only by adjusting the clearance of the front support; If the radial runout still does not meet the requirements, the rear bearing should be adjusted.

special machine for servo gate valve The lubrication of the front and rear supports of the spindle is supplied by the lubricating oil pump. The lubricating oil fully lubricates the bearing through the oil inlet hole and takes away the heat generated by the running of the bearing. In order to avoid oil leakage, oil groove sealing is adopted at the front and rear supports, that is, annular grooves with serrated sections on the outer surface of the front nut and the back support sleeve. When the spindle of the special machine for servo gate valve is rotating, due to the role of centrifugal force, The oil is thrown into the oil groove of the flange along the inclined plane (in the direction of the box), and the oil flows to the bottom of the box through the oil return hole, and then flows back to the oil pool in the left bed leg.
