The moving jaw is the overall quality of steel structure, the inner hole and groove parts after fine processing and testing, to ensure the work safety and reliability. The eccentric shaft is of high quality and high strength steel, through several precision machining, heat treatment and inspection is made, it has enough strength and rigidity. The 4 sets of bearings double row spherical roller bearing, has good performance of bearing and self-aligning. Both the fixed and movable jaw are high-quality high manganese steel castings, to prolong its service life, its shape is designed, which is symmetrical, wear can be turned around to use. The flywheel and Geneva wheel are of high quality iron castings. Their weight and structure can ensure the break The position of the two ends of the flying wheel on the eccentric shaft can be exchanged with each other and connected by the expansion sleeve.
Assembly process of moving jaw parts:
A.eccentric shaft, bearing two and cleaned with kerosene, and then the two ends of the oil baffle is installed on the eccentric shaft. Two bearing heating oil at 80-100 DEG C for about 15 minutes, the inner hole measuring bearing eccentric shaft neck is greater than 0.15, and set out the heat to the eccentric shaft at both ends of the pressure off the bearing and the shaft shoulder near the bearing until completely cooled until the gap, not more than 0.05. set after finishing clean, injection 50%-70% grease in the bearing.
B. installed at one end of the movable jaw, paper washer, and bolt fastening. At this point, the movable jaw hole stow on end, so that one end installed transparent cover down, then the eccentric shaft assembly into the moving jaw, must pay attention to: when lifting the eccentric shaft and the movable jaw hole center line consistent put the first light pressure bearing jacket, to guide, when pressed into uniform amount of gradual, but continuous knocking pressure. (not hammer percussion bearing, should be on the bearing pad on the bar, and then tap copper); when the first press bearing after loading second bearing when the program ibid. Then, 50%-70% grease in the bearing cover, then reassembled at the other side of the paper. The gasket should be fastened with bolts. After installation, the gap between the outer ring of the bearing outer ring and the cover of the cover should be 0.2-0.4, which is obtained by placing an appropriate amount of paper gasket
C. to each key are respectively arranged in the eccentric shaft keyway, which are respectively arranged in the labyrinth of inner cover, pay attention to in the right direction, the other two bearings, cleaned with kerosene, put abdapter into the bearing hole, and then installed on the eccentric shaft, according to the structure of revolving round nut, washer. Note the left and right-hand thread on the eccentric shaft, the eccentric shaft rotates to make round nuts are screwed tighter and tighter, the first rotary eccentric shaft round nut, the pressing abdapter, round nut screwing the bushing, the bearing inner ring on the seal, so repeated several times, the end of the bearing fastening and the round nut abdapter exit, with the inner ring of the bearing clearance About 1mm (in the demolition of bearings, first loosen circular nut of the eccentric shaft and then tighten the nuts on the circular sleeve bearings). The long short teeth of gasket are respectively pressed into the locking groove of the lining round nut and tighten, then pour 50%-70% lubricant in the bearing, and then which are respectively arranged in the inner loop of the cover.
