Abstract
A step-by-step compaction device used in assembly of an internal-combustion DC electric locomotive wheelset shaft-holding box is disposed on a vehicle shaft to compact a component to be compacted and comprises a hollow hack, an upper pressing plate, a connecting rod and a plurality of compaction screws, wherein the lower end of the connecting rod passes through the upper pressing plate to be connected with the vehicle shaft, the upper end passes through the hollow jack to be fixed on the hollow jack, and the upper pressing plate is connected to the multiple compaction screws to constitute a pressing frame which compacts the component to be compacted. On the premise of ensuring end face jumping of each reference face (the contact end face of an assembled part is the assembly reference face of the next assembly part), step-by-step compaction mainly outputs a certain pressure value to uniformly act on the contact face of each hot sleeve or each cold pressing part by the jack during assembly of each part by the wheelset shaft-holding box, in order to control and reduce axial transformation generated by an article during natural thermal expansion and chilling contraction to a normal temperature and further ensure sealed adherence of adjacent parts and end face jumping of contact faces. The fault of bearing-holding clearance tolerance does not exist in application of a DF7G locomotive wheelset assembled with this method.
Description
Technical field
The utility model belongs to locomotive inspection and repair technical field, relates generally to for assembling internal combustion, continuous current locomotive and rolls and embrace the substep compaction apparatus that structure wheel is used axle suspension bearing box assembling process.
Background technology
Internal combustion, continuous current locomotive roll and embrace the assembling mode that structure takes turns the parts such as right sealing ring and bearing inner race is hot charging, impact due to factors such as material and external environment conditions, in naturally cooling process, can there is certain thermal deformation in it, the contact-making surface of adjacent elements can form not closely connected, at wheel, to measuring axle suspension bearing play after assembling, meet the requirements, but use after a period of time, part there will be axle suspension bearing box bearing clearance to become large overproof fault, the traffic safety that jeopardizes to a certain extent locomotive.
Utility model content
Technical problem to be solved in the utility model is to provide internal combustion, continuous current locomotive wheel to the substep compaction apparatus of using in axle suspension bearing box assembling, makes to need the parts of hot charging can not be out of shape in group pressure process, makes the contact-making surface of installing component closely connected, reduces the loss.
The utility model is to solve the problems of the technologies described above adopted technical scheme to be: internal combustion, continuous current locomotive wheel are to the substep compaction apparatus of using in axle suspension bearing box assembling, be arranged on axletree, compacting parts are carried out to compacting, comprise hollow jack, top board, connecting rod and a plurality of compression clamping screw, the lower end of connecting rod is connected with axletree through top board, its upper end is through after hollow jack and be fixed on hollow jack, on top board, be connected with many and compress clamping screw, form a pressure rack that compacting parts are compressed.
Connecting rod described in the utility model is fixed on axletree by spindle nose gland, and spindle nose gland is fixed on axletree by clamping screw.
One end of compression clamping screw described in the utility model is fixedly connected with top board, and its other end is connected with lower platen.
The shape of lower platen described in the utility model and compacting parts match.
The beneficial effects of the utility model are:
Substep compacting is mainly axle suspension bearing box to be assembled in the assembling process of each part at wheel, guarantee under the prerequisite of each datum level (the contact end face of assembly is the assembling datum level of next assembly) end face run-out, by jack, export certain force value stepless action in the contact-making surface of each hot jacket or the part of colding pressing, control reduce object in natural heat expansion and shrinkage to the axial deformation producing in the process of normal temperature, and then guarantee the closely connected property of adjacent elements and the end face run-out of contact-making surface.
Accompanying drawing explanation

In figure: 1, axletree, 2, driven gear, 3, sealing ring II, 4, technique cushion block, 5, lower platen, 6, clamping screw, 7, spindle nose gland, 8, top board, 9, hollow jack, 10, nut, 11, connecting rod, 12, seal cover II, 13, flank axle suspension bearing, 14, axle-hang box, 15, non-flank axle suspension bearing, 16, seal cover I, 17, sealing ring I.
The specific embodiment
Illustrate by reference to the accompanying drawings embodiment of the present utility model.
With specific embodiment, the utility model is illustrated by reference to the accompanying drawings:
The assembling DF7G type locomotive wheel of take is example explanation to sealing ring II 3, and Fig. 1 is axletree 1 and driven gear 2 assemblies, and the gear side of assembly is stood on workbench downwards, to overhaul, apolegamy, clean qualified sealing ring II 3 heating, sealing ring II 3 labyrinths that heat are installed on axletree sealing ring II mount pad upward, rotary seal circle II is until turn motionless, then install rapidly technique cushion block 4, make it be pressed in sealing ring II 3 upper surfaces, and lift compaction tool assembly, compaction tool assembly is containing lower platen 5, clamping screw 6, spindle nose gland 7, top board 8, hollow jack 9, nut 10, connecting rod 11, spindle nose gland 7 passes through bolt assembly and connection with axletree 1, connecting rod 11 lower ends are connected with spindle nose gland 7 by screw thread, top is fixedly connected with by nut 10 through hollow jack 9, lower platen 5, clamping screw 6, top board 8 consists of cage shape one frock (can form in advance), after each frock has connected, start hollow jack 9, the hollow main shaft of hollow jack 9 stretches out and withstands nut, set the output pressure value of hollow jack, the pressure of hollow jack output reacts on top board 8, power is transmitted by clamping screw 6, finally act on sealing ring II 3, schematic diagram is as Fig. 3, after circle II 3 to be sealed is naturally cooling, each frock is taken off, with closely connected between clearance gauge inspection sealing ring II 3 and driven gear 2 end faces, with dial gauge, check the end face run-out of sealing ring II 3, if overproof, change.
DF7G type locomotive is taken turns right sealing ring I, flank axle suspension bearing (inner ring), non-flank axle suspension bearing (inner ring) hot charging and is all needed to adopt compaction tool compacting assembling, the embodiment of its specific embodiment and sealing ring II basically identical (except the length of screw rod 6 and the output pressure value of jack there are differences).
After each hot charging parts hot charging of axle suspension bearing box, all adopt compaction tool compacting assembling, thereby guarantee the closely connected property of adjacent elements and the end face run-out of contact-making surface.
