flying shear accomplished cutting the head and end of the rolling piece
after rough rolling in usual ,when accident occurs ,shattering or segmenting
the rolling piece. Material of the rolling piece : carbon constructional
steel, carbon constructional quality steel, low-alloy steel.
2. It has
good rigidity , resistance to impact ,transmitting large torque and run-stop
gearbox features compact structure, light weight, small volume, high ability
of load ,low noise and vibration
gearbox can achieve test of temperature and vibration automatically.
gear is manufactured by high-quality alloy steel 20CrNi2MoA with carburizing
and quenching. The tooth surface hardness is HRC57+4.The gear is modified
with serrated form .The class of precision is 5～6.The material of cutting
case s structural style is horizontal split structure which is combined with
high intensity bolt , which is manufactured conveniently and fine
appearance. The case is welded manufactured which is annealed after welding
.The case will be dealt with aging treatment in order to eliminate residual
stress. So, the case deforms hardly .
gearbox adopts mechanical sealing, which has good effect. It's sealing
structure is reliable and non-maintaining .
gearbox uses forced spray oil lubrication, the lubrication pipelines is
distributed in or out of the gearbox, which can lubricate the gear and
bearing sufficiently. The oil inlet and the oil discharge mouth are mounted
on the gearbox .The pressure switch, the flux monitor and the cut-off valve
are mounted near the oil inlet. The pressure switch and the flux monitor can
monitor the oil supply and feed back the pressure and flux signal which is
switch quantity or analog quantity to primary control system.
