Description
Technical field
The utility model relates to large-scale vertical speed reducer technical field, specifically, is a kind of being arranged in the large-scale vertical speed reducer, is the pipeline structure of high pressure combination bearing fuel feeding.
Background technique
The high-pressure oil pipe of tradition large-scale vertical speed reducer generally all is to be placed on outside the casing of retarder; One section high-pressure oil pipe is connected to upper box base plate place by diverter valve piece jointing; Another section high-pressure oil pipe is connected on the hydrostatic bearing of combination bearing from the upper box base plate again; Leakage point on the oil feed line is many like this, and monnolithic case is attractive in appearance inadequately.In addition; The upper box peep hole of vertical type speed reducer (change gear) originally has only 1/4th or 1/5th of hydrostatic bearing quantity; If casing inner high voltage oil connection is loosening or the damage position of high-pressure oil pipe not near peep hole; Then can't online speed reducer high-pressure oil pipe and joint directly be repaired or replaced, and must speed reducer be pulled out from the working machine bottom, speed reducer is disintegrated; Could keep in repair or change the high-pressure oil pipe and the joint of box house, the maintenance of complete machine is long in time limit and cost is higher.
The model utility content
The purpose of the utility model provide a kind of simple in structure, rationally distributed, the leak point is few, can carry out the high pressure combination bearing oil feed line of the large-scale vertical speed reducer of repair and replacement efficiently and easily.
For solving above technical problem; The oil feed line structure of the built-in high pressure combination bearing of a kind of large-scale vertical speed reducer that the utility model provides; Comprise a plurality of high-pressure oil pipes (2) that are arranged in the cylindrical speed reducer upper box (1); One end of each high-pressure oil pipe (2) links to each other with the high pressure filler opening (7) of centralized arrangement at upper box oil sump base plate place respectively through articulation body or end straight coupling body (3); One-way valve (4), built-up joint (5) and articulation body (6) that the other end passes through to link to each other successively are respectively to each self-corresponding hydrostatic bearing fuel feeding; One-way valve (4), built-up joint (5) and articulation body (6) that same high-pressure oil pipe (2) is corresponding are vertically arranged, have first peep hole (8) corresponding with high pressure filler opening (7), second peep hole (9) corresponding with high-pressure oil pipe (2) on the sidewall of said upper box (1).
As preferably; Totally 16 of said high-pressure oil pipes (2), correspondence are arranged on totally 16 of the interior oil supply galleries (10) of hydrostatic bearing, and said oil supply gallery (10) is circle distribution at grade; Every adjacent two oil supply galleries (10) constitute one group; The end that same group of oil supply gallery (10) links to each other with articulation body (6) is drawn close each other and is " eight " font, totally 8 of said second peep holes (9), and correspondence is arranged between two high-pressure oil pipes (2) of same group.
The beneficial effect that the utlity model has:
1) directly filler opening and high pressure combination bearing actuator port are coupled together by whole single high-pressure oil pipe; Reduced leakage point,, can not pollute external environment condition even there have leakage also only to leak at speed reducer to be inner; And reduced taking up room, rationally distributed, monnolithic case is more beautiful and clean;
2) first peep hole corresponding with the high pressure filler opening can be directly when opening its handhole cover repairs or replaces the joint at high-pressure oil pipe filler opening place, with the second corresponding peep hole of high-pressure oil pipe; Can be directly when opening its handhole cover the joint of oil feed line be repaired or replaced; In the speed reducer using process, unusual if fuel oil injection piping occurs, can be in the speed reducer peripheral operation; The joint at direct maintain and replace high-pressure oil pipe or two ends; Need speed reducer not pulled out under working machine, speed reducer is disintegrated, thereby improve maintenance efficiency and significantly reduced maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that the two ends of Fig. 1 mesohigh oil pipe connect schematic representation.
Fig. 3 is that the A of Fig. 2 is to view.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Like the oil feed line structure of Fig. 1, the built-in high pressure combination bearing of a kind of large-scale vertical speed reducer shown in Figure 2, form by high-pressure oil pipe 2, articulation body or end straight coupling body 3, one-way valve 4, built-up joint 5 and the articulation body 6 etc. identical with high-pressure oil pipe 2 quantity.High-pressure oil pipe 2, articulation body or end straight coupling body 3, one-way valve 4, built-up joint 5 and articulation body 6, hydrostatic bearing respectively are 16, all are arranged in the cylindrical speed reducer upper box 1, all have L shaped oil supply gallery 10 in each hydrostatic bearing.
One end of each high-pressure oil pipe 2 links to each other with the high pressure filler opening 7 of centralized arrangement at upper box oil sump base plate place respectively through articulation body or end straight coupling body 3, and one-way valve 4, built-up joint 5 and articulation body 6 that the other end passes through to link to each other successively are respectively to each self-corresponding hydrostatic bearing fuel feeding.High pressure filler opening 7 is arranged on the speed reducer dead astern.Same high-pressure oil pipe 2 corresponding one-way valve 4, built-up joint 5 and articulation bodies 6 are vertically arranged.Have on the sidewall of upper box 1 corresponding with high pressure filler opening 7 first peep hole 8, with corresponding second peep hole, 9, the first peep holes 8 of high-pressure oil pipe 2, second peep hole 9 respectively correspondence be provided with handhole cover.
