Description
Technical field
The present invention relates to gear housing support apparatus, more particularly, it relates to the installation method of a kind of milling train gear housing.
Background technology
In the cold rolling processing of seamless steel pipe, the power source of pipe conveying typically uses feeding rotary gear box, and this gear-box is a whole set of
It is placed in mixed earth foundation ditch.Owing to being mounted with the vitals of a whole set of feeding slew gear, existing input equipment in gear-box
(at one), also has an output device (at three), also electric motor belt driving member at two, pipe gear-box to be passed chuck axis
Hole, for guaranteeing mating of gear-box and miscellaneous part, therefore installation accuracy requires height, should ensure vertical direction, ensure again
Horizontal direction, also to ensure parallel with rolling centerline；Generally gear housing can meet the technology of equipment when initially installing
Required precision, but in routine use, gear housing (lower box) there will be the phenomenons such as loosening, will become if disposing not in time
The potential faults of equipment；And cause gear housing (lower box) to loosen the main cause rocked being: one is big for equipment rolling specs,
The shock loading born is relatively big, and higher to fixing bolt fastening requirements, foundation ditch arranges on the low side, especially with the bolt of lower box (block)
It is that trisquare shape minor face position only has the fixing bolt of connection at, and fixed effect can not meet the impact of big specification seamless steel pipe and carry
Lotus, two is the inclination that the reasons such as installation because of gear housing, Excavation Settlement cause, lower box fastening bolt and nut loosening, three
Being pipe bending, in rolling, the output link of logical the move about gear-boxes such as leading screw, mandrel chuck device, angle output device will be anti-
Active force passes to gear housing, causes component abrasion aggravation in casing, produces circular runout and axial float, cause lower box
With loosening of foundation ditch connecting bolt；And the rolling specs of equipment will not change, shock loading will exist, therefore tooth once occurs
Wheel casing is connected the loosening it is necessary to dispose in time of fixing bolt with foundation ditch, disposes and may result in follow-up equipment fault not in time,
Having influence on operation level and production capacity, the quality of equipment, simultaneous faults frequently adds the load of overhaul of the equipments operation.
Method of disposal after feeding swiveling gear casing is connected fixing bolt looseness with foundation ditch at present has two kinds, it may be assumed that
1, periodic maintenance fastening: be exactly that the regular lower box (block) to feeding rotary gear box is connected fixing spiral shell with foundation ditch
Bolt carries out terminal operation, and its feature is exactly terminal operation time few (4 hours), can recover bolt tightness, but operation ring
Border is narrow, narrow, it is necessary to open foundation ditch cover plate, enters in foundation ditch and carries out, fastens many places bolt one by one, and operation is the most inconvenient,
Sledgehammer can only be used to tap mode carry out, labor intensity is high, and there is certain potential safety hazard, and fastening effect is not good enough, is only capable of
Maintain relatively short period of time, repeat operation intensity high, the bolt that the fastening especially can only judged the case as it stands has loosened, and can not correct
The precision destroyed because of bolt looseness, therefore loosens hidden danger and the most thoroughly gets rid of, and only field failure is disposed.
2, correction is periodically installed: be exactly periodically (cycle is longer, usual more than 5 years, and some equipment is not correcting after installing)
Feeding rotary gear box is removed again, installation exercise, correct every precision in an installation, its feature is exactly installation accuracy
Height, adjusts the problem that the factors such as sedimentation, inclination cause, and can effectively recover original precision, but shut down activity duration length (seven
My god), correction operation operation loaded down with trivial details (screw jack is without fine adjustment function), the Work tool of correction operation is used and operation technical ability
Require higher, and do not solve the problem that foundation ditch bolt is on the low side, after reusing, the loosening event of gear housing still can occur
Barrier.
In sum, during current seamless steel pipe cold-rolling mill gear housing looseness fault is disposed, there is certain deficiency, it is necessary to
Bonding apparatus feature and production improve accordingly.
