附件24.4 4 The points for assembly and notes for attention (1)Select components carefully and keep them clean (2)Can not change the shape of every parts such as rounding chamfer,Round Edges and so on. (3)Needles which can not be left out should be filled with the inner ring of the Bearing Block.Needle bearing should be pressed into the vertical hole of the front and rear covers Needles should be flexible to rotate in the Bearing retainer (4)When parallel key of the Minor axis and long axis matches with the gear,their lateral clearance should not be too large.Of course,top surface can not be a collision and friction and Shaft and gears can be easy to promote within.What's more.Axis should not produce the phenomenon of radial swing in gear (5)CB-type gear pumps have 0.13~0.16 mm for the radial clearance and 0.03 mm for the axial clearance. (6)Rotating the Driving shaft(long axis)after the gear pumps is Completed assembled.To ensure that it is rotated by hand without let or hindrance. (7)Should pay attention to switch of lateral plate and it's Installation position for the high-pressure pumps with automatic compensating device to oil pressure.
