Abstract
The utility model relates to a lubricated mechanism of entry driving machine pars contractilis, including the floating seal seat, float seal carrier with the cooperation of floating seal seat, in run through installation cut main shaft on the unsteady seal carrier, cooperation department of seal carrier and floating seal seat of floating still sets up the cavity, in in the cavity still cooperate the installation floating seal on the unsteady seal carrier still opened on the floating seal seat a set of with the oilhole that the cavity is linked together. The utility model has the advantages of simple structure, through set up a set of oilhole on the floating seal seat, two chamber UNICOMs of bearing and floating seal have been guaranteed, make lubricating oil can give certain lubrication and the cooling of floating seal through the oilhole when giving bearing lubrication, O type circle prevents that the lubricating oil in the floating seal from leaking outward, the 2nd O type circle and the 3rd O type circle prevent oil circuit and water route intercommunication, set up a set of oil filler point in addition on the cut main shaft, can smooth and easy oiling when guaranteeing crude oil seal lock stopper, there is sufficient fluid lubricated in guaranteeing the pars contractilis cavity.
Description
Technical field
The utility model relates to technical field of mechanical equipment, particularly relates to flexible part of heading machine lubricating structure.
Background technique
At present, the lubricating structure oiling difficulty of existing flexible part of heading machine, fluid easily leaks, and development machine parts thereof feed lubrication is not enough, and oil circuit and water route easily intercommunication occur, and have a strong impact on transmission efficiency and the working life of flexible part of heading machine.
Model utility content
The applicant is for above-mentioned existing issue, be studied improvement, a kind of flexible part of heading machine lubricating structure is provided, it efficiently solves flexible part of heading machine oiling difficulty and the fluid problem of easily leaking, avoid oil circuit and water route intercommunication, substantially increase transmission efficiency and the working life of flexible part of heading machine.
The technological scheme that the utility model adopts is as follows:
A kind of flexible part of heading machine lubricating structure, comprise floating seal seat, floating seal frame coordinates with described floating seal seat, run through on described floating seal frame and cut main shaft is installed, the cooperation place of described floating seal frame and floating seal seat also arranges cavity, also coordinate in described cavity, on described floating seal frame and floating seal is installed, described floating seal seat also has one group of oilhole be connected with described cavity.
Further improvement as technique scheme:
In the joint of described floating seal frame and floating seal seat, the O type circle for preventing lubricant oil from leaking outside also is set;
Between described floating seal seat and cut main shaft, at the periphery of described cut main shaft also fitted seal cover, 2nd O type circle is also set between the outer ring of described stuffing box gland and floating seal seat, the 3rd O type circle is also set between the inner ring of described stuffing box gland and cut main shaft;
Also oil hole is offered in described cut main shaft.
The beneficial effects of the utility model are as follows:
The utility model structure is simple, easy to use, by offering one group of oilhole on floating seal seat, ensure that bearing and floating seal Liang Qiang UNICOM, make lubricant oil to while bearing lubrication by oilhole to the certain lubrication of floating seal and cooling, O type circle prevents the lubricant oil in floating seal from leaking outside, 2nd O type circle and the 3rd O type circle prevent oil circuit and water route intercommunication, one group of oil hole is offered in addition on cut main shaft, energy smooth and easy oiling during guarantee crude oil hole plug, ensures there are enough oil lubrications in pars contractilis cavity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlargement structural representation of Fig. 1.
Wherein: 1, floating seal seat; 2, floating seal frame; 3, floating seal; 4, cut main shaft; 5, stuffing box gland; 6, an O type circle; 7, the 2nd O type circle; 8, the 3rd O type circle; 9, oilhole; 10, oil hole.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1 and Figure 2, flexible part of heading machine lubricating structure comprises floating seal seat 1, floating seal frame 2 coordinates with floating seal seat 1, run through on floating seal frame 2 and cut main shaft 4 is installed, floating seal frame 2 also arranges cavity with the cooperation place of floating seal seat 1, also coordinate in cavity, on floating seal frame 2 and install floating seal 3, floating seal 3 is communicated with bearing (not marking in figure) installation cavity by cavity 3, oilhole 9.Floating seal seat 1 also has one group of oilhole be connected with cavity 9, by injecting lubricant oil in oilhole 9, make lubricant oil enter cavity lubricate bearing and floating seal 3 and cool, the O type circle 6 for preventing lubricant oil from leaking outside also is set in floating seal frame 2 and the joint of floating seal seat 1.Between floating seal seat 1 and cut main shaft 4, in the periphery of cut main shaft 4, also fitted seal overlaps 5, also arranges the 2nd O type circle 7 between the outer ring of stuffing box gland 5 and floating seal seat 1, also arranges the 3rd O type circle 8 between the inner ring of stuffing box gland 5 and cut main shaft 4.2nd O type circle 7 and the 3rd O type circle 8 can prevent oil circuit and water route intercommunication.Oil hole 10 is also offered in described cut main shaft 4; due under ore deposit during operation the oilhole 9 of floating seal seat 1 side easily by foreign matters from being blocked; and this oil hole 10 has the protection of inner spline housing and big gun head; can keep unimpeded; when oilhole 9 blocks; this oil hole 10 as oil hole for subsequent use, thus makes to keep enough oil lubrications in the cavity of pars contractilis.
More than describing is to explanation of the present utility model, and be not the restriction to model utility, the utility model limited range is see claim, and when without prejudice to basic structure of the present utility model, the utility model can do any type of amendment.
