Description

The gearbox of adjustable sealing structure
Technical field
The utility model relates to a kind of curved fast case, especially a kind of gearboxes of adjustable sealing structure.
Background technique
Gearbox is common component in machinery equipment, including cabinet, and multiple transmission shafts, transmission shaft are supported by cabinet End extend to the outside of cabinet, bearing is equipped between transmission shaft and cabinet, the outside of bearing is equipped with bearing gland, bearing pressure Lid is fixedly connected by bearing gland bolt with cabinet, and bearing gland is sleeved on transmission shaft, in transmission shaft and bearing gland Sealing ring is equipped between heart hole.This sealing structure can not adjust, and after running for a period of time, grind between sealing ring and transmission shaft Damage, leads poor sealing, oil leakage phenomenon occurs, needs replacing sealing ring, thus the gearbox consumption sealing ring of this structure compared with It is more, operating cost is increased, the high-grade more aobvious protrusion of sealing ring having higher requirements especially for sealing ring material.
Summary of the invention
The purpose of the utility model is to provide a kind of sealing structure, simple and seal degree is adjustable, extends sealing ring uses Time, reduce operating cost adjustable sealing structure gearbox, overcome the deficiencies in the prior art.
The gearbox of the adjustable sealing structure of the utility model, including cabinet and the transmission shaft being supported on cabinet, transmission The end of axis extends to the outside of cabinet, and bearing is equipped between transmission shaft and cabinet, and the outside of bearing is equipped with bearing gland, bearing Gland is fixedly connected by bearing gland bolt with cabinet, and bearing gland is sleeved on transmission shaft, transmission shaft and bearing gland Sealing ring is equipped between centre bore, having section on the outside of the sealing ring is in the annular groove of triangular shape, the inner side edge of annular groove There is the first inclined-plane of annular, sealing ring gland is set on transmission shaft, has protruding ring on the inside of sealing ring gland, in protruding ring On have with first inclined-plane match annular the second inclined-plane, the sealing ring gland pass through sealing ring gland bolt and axis Pressure cap is fixedly connected, and adjustment gasket is equipped between bearing gland and sealing ring gland;Cabinet and all biographies for having extension end Sealing structure between moving axis is all the same.
The gearbox of the adjustable sealing structure of the utility model after running a period of time, goes out between sealing ring and transmission shaft It now wears, detachable lower seal gland, the thickness of corresponding thinned trimmer, then screwing hermetic circle gland, makes on sealing ring gland The circumferential sealing ring of protrusion on annular groove in move a certain distance, i.e., the second inclined-plane presses to the first inclined-plane, and sealing ring is in pressure Effect is lower to generate a certain amount of deformation, and making sealing ring, adapter sleeve ensure that sealing on transmission shaft again, sealing that no replacement is required Circle, can be repeated several times, and have sealing structure is simple and seal degree is adjustable, extends sealing ring use the time, reduce operating cost The advantages of.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention;
Fig. 2 is the portion A shown in FIG. 1 enlarged diagram;
Fig. 3 is the structural schematic diagram of sealing ring gland shown in FIG. 1;
Fig. 4 is the structural schematic diagram of sealing ring shown in FIG. 1.
Specific embodiment
It is as shown in Figure 1,2,3, 4: the gearbox of the adjustable sealing structure of the utility model, including cabinet 1 and it is supported on case Transmission shaft 7 on body 1, the end of transmission shaft 7 extend to the outside of cabinet 1, bearing 8 are equipped between transmission shaft 7 and cabinet 1, i.e., Transmission shaft 7 is supported on cabinet 1 by bearing 8.The outside of bearing 8 is equipped with bearing gland 3, and bearing gland 3 passes through bearing pressure Bonnet bolt 2 is fixedly connected with cabinet 1.Bearing gland 3 is sleeved on transmission shaft 7, the centre bore of transmission shaft 7 and bearing gland 3 it Between be equipped with sealing ring 5.It is in the annular groove 12 of triangular shape that, which there is section in the outside of sealing ring 5, and the inner side edge of annular groove 12 has annular First inclined-plane 13.Sealing ring gland 6 is set on transmission shaft 7, there is protruding ring 10 in the inside of sealing ring gland 6, in protruding ring There is the second inclined-plane 11 of the annular to match with the first inclined-plane 13 on 10.Sealing ring gland 6 passes through sealing ring gland bolt 4 and bearing Gland 3 is fixedly connected.Adjustment gasket 9 is equipped between bearing gland 3 and sealing ring gland 6.Cabinet 1 and all there is extension end Sealing structure between transmission shaft is all the same.
The gearbox of the adjustable sealing structure of the utility model, after running a period of time, between sealing ring 5 and transmission shaft 7 It wears, detachable lower seal gland 6, the thickness of corresponding thinned trimmer 9, then screwing hermetic circle gland 6, makes sealing ring pressure Protruding ring 10 on lid 6 moves a certain distance in the annular groove 12 on sealing ring 5, i.e., the second inclined-plane 11 presses to the first inclined-plane 13, sealing ring 5 generates a certain amount of deformation under pressure, and deformation result is that the diameter of bore of sealing ring 5 reduces, and makes close Adapter sleeve ensure that sealing on the transmission shaft 7 again for seal 5, no replacement is required sealing ring 5, can be repeated several times, there is sealing to tie Structure is simple and seal degree is adjustable, extends sealing ring uses the time, reduces the advantages of operating cost.
