1. Bowl bearings and seals
When installing the bowl-shaped bearing,
taking care not to make the rope break something slinger (available hardwood
material support in the rope between).
Assembly, the spherical bearing
should be scraped to ensure that the crushing cone and bowl each other spherical
outer contact with the inner ring should ensure that the annular gap of
0.35-0.5mm.
Bowl bush around the perfusion bar alloy nail in the bowl
bearing shelves, rotating along the circumferential how to prevent the bowl
bearing.
Bowl-shaped bearing frame and use (sales) and fixed in the work
bowl bearing frame and the gap must be handled immediately.
2. Conical
bushing
Bushes empty eccentric shaft to research co-injection of zinc
alloy to prevent the sleeve rotation, zinc alloy to be full of all clearance,
due to the thermal Note the sake of the zinc alloy may cause deformation of the
sleeve, so better check the size of the new cone Set d1 and d2 incorrect and B,
etc. should be promptly amended the actual size of the sets of inner diameter of
preparation in order to maintain the original with the manufacture of spare
parts should be eccentric.
3, Spring
(1) the role of the spring
when the crusher into the protect the crusher can not be broken material is not
damaged, the spring pressure crusher broken power crusher spring in the normal
working hours is not moving, just fall into the iron overloading of crusher
crushing chamber when the lift supporting the phenomenon of the spring is
compressed.
(2) the upper part of the crusher during normal working hours
occurred beating, this is not a normal phenomenon must be carefully analyzed,
the cause and take measures to remove the incorrectly compression spring not
only does not work, but may occur part of the damage, because of the compression
spring will cause the increase of the crushing force.
Caused by the
crusher the upper beating for several reasons:
A. ore uneven or to mine
too much
B. ore contains too many small pieces and powdered ore or
humidity is too large.
C. entrance to the mine clearance is too small.
4. machine exposed to the rotating part, should be added to the shield, the
shield is owned by the user.
5.Cylindrical bushing and the frame body with
the third transition is again injected into the upper slot in the bush in order
to prevent the bush rotation, zinc alloy, and replace the new bushing should
frame body size preparation, because crusher after long hours of work, loading
and unloading will inevitably lead to change with the relationship. If the gap
is too general cause the bushing to rupture.
