Description
Technical field
The utility model relates to field of industrial machinery, particularly relates to a kind of arbor portion leakage of oil sealing configuration.
Background technique
At present, to the conventional method that leakage of oil situation in arbor portion on the equipment such as speed reducer, blower fan processes be: change or repair the arbor or main gland that are are worn and torn by outside framework oil seal lip, the high and length consuming time of rehabilitation cost.
Model utility content
The utility model embodiment discloses a kind of arbor portion leakage of oil sealing configuration, for solving the problem of arbor portion leakage of oil.
A kind of arbor portion leakage of oil sealing configuration that the utility model embodiment provides, comprising: main gland, secondary gland and outside framework oil seal;
Described secondary gland is inserted in arbor and is fixedly mounted on described main gland;
Described outside framework oil seal is arranged on described secondary gland, or is arranged between described secondary gland and described main gland.
Alternatively, described arbor is provided with axle sleeve;
Described outside framework oil seal is arranged on described axle sleeve.
Alternatively, described axle sleeve is thin-wall shaft sleeve.
Alternatively, described secondary gland is mounted by means of bolts on described main gland.
As can be seen from the above technical solutions, the utility model embodiment has the following advantages:
In the utility model embodiment, a kind of arbor portion leakage of oil sealing configuration comprises: main gland, secondary gland and outside framework oil seal; Described secondary gland is inserted in arbor and is fixedly mounted on described main gland; Described outside framework oil seal is arranged on described secondary gland, or is arranged between described secondary gland and described main gland.In the utility model embodiment, install secondary gland additional on described main gland, outside framework oil seal is arranged on secondary gland, and to arbor, portion seals, thus solves the problem of arbor portion leakage of oil.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of a kind of arbor portion leakage of oil sealing configuration in the utility model embodiment;
Fig. 2 is the another kind of structural representation of a kind of arbor portion leakage of oil sealing configuration in the utility model embodiment.
Embodiment
The utility model embodiment discloses a kind of arbor portion leakage of oil sealing configuration, can solve the problem of arbor portion leakage of oil.
Refer to Fig. 1 or Fig. 2, a kind of arbor portion leakage of oil sealing configuration in the utility model embodiment, comprising: main gland 1, secondary gland 2 and outside framework oil seal; Described secondary gland 2 is inserted in arbor and is fixedly mounted on described main gland 1; Described outside framework oil seal is arranged on described secondary gland 2, or is arranged between described secondary gland 2 and described main gland 1.Wherein, marking 3 is the mounting point of outside framework oil seal.
Preferably, described arbor is provided with axle sleeve, described outside framework oil seal is arranged on described axle sleeve.Be understandable that, sometimes, when not the mating of the diameter of axle and outside framework oil seal of arbor, first on arbor, axle sleeve can be installed, by this axle sleeve of skeleton oil seal, thus reach the effect of arbor portion sealing.In addition, preferably, described axle sleeve is thin-wall shaft sleeve.
Preferably, described secondary gland 2 is fixedly mounted on described main gland 1 by bolt 4, is fixed by bolt, more reliable and more stable, durable.
For ease of understanding, the embodiment described by Fig. 1 or Fig. 2, is described arbor portion leakage of oil sealing configuration a kind of in the utility model embodiment with a practical application scene below:
Input (output) axle of speed reducer, generally adopts skeleton oil seal, when the lip of outside framework oil seal be may wear to recessed more than 0.2mm by axle, greatly will reduce the sealability of oil sealing.If repair this groove, this axle will be made on the one hand to produce distortion or stress is concentrated, on the other hand for the cost repaired main equipment and cost too large.Now again can make an end cap, adopt displacement method, the position of outside framework oil seal outwards mobile 5 ~ 8mm can to stagger groove.In emergency circumstances, in order to this groove that staggers can fill counter for outside framework oil seal.
Motor side for JZQ type speed reducer and centrifugal blower can adopt the main gland of Fig. 2 form, and L is widened 5 ~ 8mm; For large centrifugal fan, near the logical lid of fan blade one end, cumbersome because changing outside framework oil seal, preferably logical lid being designed to not only can with outside framework oil seal but also available wool felt seal form, as Fig. 1 structure.After outside framework oil seal loses efficacy, (this oil sealing was cut off taking-up, be replaced with wool felt and ensure that spill port is unimpeded) use instead wool felt sealing time, between primary and secondary lid cover, surface of contact should smear happy safe 660 sealers or the thick asbestos slate sealing of pad 1mm, like this can spreadable life of extension device.
For large-scale roots blower, because the large gland and reparation main shaft groove of tearing equipment open are cumbersome, a secondary gland can be processed, install to after loading onto outside framework oil seal on main gland, two lid surface of contact should be coated with happy safe 660 sealers or pad asbestos slate sealing, and the tapped hole of fixed joint gland should smear happy safe 626 sealers.When processing secondary gland, internal diameter car to than after the large 0.1mm of the new oil sealing of input shaft, install on main gland and join brill fixed hole, then remove and be worked into given size, as Fig. 2.
Outside framework oil seal is filled on secondary gland, run into this place's diameter of axle be not 5 integral multiple maybe this place roughness spy difference time, the thin-wall shaft sleeve that an external diameter is the integral multiple of 5 can be processed, after the internal surface of cover evenly coats happy safe 600 sealers, install on axle, then select suitable standard outside framework oil seal.
Above a kind of arbor portion leakage of oil sealing configuration provided by the utility model is described in detail, for one of ordinary skill in the art, according to the thought of the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
