Customized Castings And Forgings Of Thrust Roller Wheel Steel Wheel
1. Product description of thrust roller wheel Castings And Forgings
Hydraulic retaining wheel is used to control the axial movement of
the rotary kiln body, so that the wheel belt and supporting wheel
can be evenly worn on the full width, but also to ensure the
straightness of the center line of the kiln body, so that the size
of the gear meshing well, reduce power consumption.
2. Fault protection measures for thrust roller wheel Castings And Forgings
In order to avoid similar problems in the future, we have taken
corresponding protection measures based on the above analysis:
(1) Improve the existing unreasonable structure or hidden parts;
(2) Strict equipment management, improve and refine feasible
operation specifications for the implementation of various
projects;
(3) In the field maintenance, the management department should
strictly quantify the installation technical requirements and
indicators, and the construction unit should make detailed
arrangements for the feasibility of the operation plan according to
the requirements;
(4) Ensure that all common inspection data meet the requirements
and specifications;
(5) Ensure key quality control points such as interference of shaft
hole fit, comprehensive mechanical properties of shaft and surface
hardness of wheel disc;
(6) Control whether each bolt reaches the required strength grade
index, sealing ring performance is up to standard and other
details;
(7) Strengthen the technical training for workers, do a good job in
daily spot inspection and maintenance, and report any problems in
time.
3. Analysis of the reasons for the failure of thrust roller wheel Castings And Forgings
Although there is no big fault in the hydraulic system, poor
treatment may also cause kiln shutdown and production reduction.
(1) The interference of the shaft hole of the retaining wheel is
small
The baffle wheel and the shaft use a flat key interference
connection, in order to prevent the baffle wheel axial channeling,
the upper part of six anti-loosening bolts; The matching tolerance
of the retaining wheel and solid shaft is selected according to the
load transferred by the retaining wheel; According to the
calculation of retaining wheel shaft hole matching theory
selection; Once the actual interference is less than this value,
the pressure on the mating surface will be too small to meet the
working conditions under this working condition, resulting in
relative sliding between the shaft holes, and the torsion force
will act directly on the key, so that the torque transferred by the
interference fit of the shaft hole will be changed into the torque
transferred together with the key. Under impact load, especially
when the key is also selected relatively loose fit can not meet the
requirements of use, it is easy to cause rolling key, block wheel
and other fault phenomenon.
(2) Axis class itself
Shaft parts once improper material selection, may lead to its own
mechanical properties can not meet the requirements of use;
Improper processing or heat treatment may lead to stress
concentration or crack source, which can easily lead to cracking
failure. Rapid heating and cooling during welding repair will
change the toughness of the matrix, and if the residual stress can
not be eliminated well, it is easy to cause crack failure.
