After the end external cylindrical surface of the inner hole indentation fork truck differential mechanism 200 of another bearing 100, computer control system control three
The upside electromagnet 105B of position four-way valve 1 is powered, and the oil inlet A1 of three-position four-way valve 1 is connected to pressure port T1, out
Hydraulic fluid port B1 is connected to oil return opening P1, and the piston rod 1 of upper hydraulic cylinder 9 retracts, and upper lifter plate 7 is on dynamic bearing grip slipper 10
It moves, another bearing 100 can smoothly be deviate from out of semicircular ring 1 and semicircular ring 2 1001.
Computer control system control four downside electromagnet 108A of three-position four-way valve be powered, three-dimensional four-way valve 4 108 into
Hydraulic fluid port A4 is connected to pressure port P4, and oil outlet B4 is connected to oil return inlet T 4, and hydraulic motor 12 rotates, left vee-block 26, right vee-block
It is located remotely from each other;
The upside electromagnet 106B that computer control system controls three-dimensional four-way valve 2 106 is powered, three-dimensional four-way valve 2 106 into
Hydraulic fluid port A2 is connected to pressure port T2, and oil outlet B2 is connected to oil return opening P2, and the piston rod two of lower hydraulic cylinder 2 retracts downwards.
Rear clamp nut 42, right clamp nut are unscrewed, after-opening washer 45, open front washer are removed from side, to rear side
Compact heap 46 after overturning, forward compact heap before side to overturn, remove fork truck differential mechanism 200, realize the two of a fork truck differential mechanism 200
End is all made of the same hydraulic motor 12 and realizes centralized positioning, completes the indentation of differential mechanism both ends bearing, another is poor
Fast device is placed on differential support plate 34, is repeated the above process, and realizes the double-sided bearings indentation of the differential mechanism.
