Abstract

The utility model solves the technological scheme that its technical problem adopts: a kind of high leak tightness speed reducer, comprises casing, end cap, seal ring and the pressure ring for press seal circle; Described end cap is arranged on the opening of casing, described seal ring is arranged on end cap inwall, the both sides of described seal ring are the inclined-plane that outer ring width is less than inner race width, described end cap exterior edge face offers the threaded annular groove of tool, described pressure ring has the threaded ring-like protrusion mounting end of the tool matched with annular groove and annular groove internal thread, described pressure ring also has the annular hypotenuse one corresponding with seal ring ramp with seal ring joint; Described end cap inwall also have the annular hypotenuse two corresponding with another inclined-plane on seal ring.The utility model with the addition of pressure ring arrangements on original speed reducer, and it can press seal circle further, thus makes speed reducer sealing effect better.

Description

High leak tightness speed reducer
Technical field
The utility model relates to a kind of high leak tightness speed reducer.
Background technique
Owing to there being the lubricant oil for realizing functions such as lubricating, antirust in the speed reducer of speed reducer, and speed reducer has been not hermetic casing, and therefore leakage of oil is the modal problem in speed reducer field, is also a great problem in related domain.Oil-leakage-prevention way common in prior art arranges seal ring on end cap, but this method leakage of oil situation is serious, can not well seal speed reducer.
Model utility content
The technical problems to be solved in the utility model is: the deficiency solving speed reducer poor sealing in prior art, provides a kind of high leak tightness speed reducer.
The utility model solves the technological scheme that its technical problem adopts: a kind of high leak tightness speed reducer, comprises casing, end cap, seal ring and the pressure ring for press seal circle; Described end cap is arranged on the opening of casing, described seal ring is arranged on end cap inwall, the both sides of described seal ring are the inclined-plane that outer ring width is less than inner race width, described end cap exterior edge face offers the threaded annular groove of tool, described pressure ring has the threaded ring-like protrusion mounting end of the tool matched with annular groove and annular groove internal thread, described pressure ring also has the annular hypotenuse one corresponding with seal ring ramp with seal ring joint; Described end cap inwall also have the annular hypotenuse two corresponding with another inclined-plane on seal ring.The utility model with the addition of pressure ring arrangements on original speed reducer, and it can press seal circle further, thus makes speed reducer sealing effect better.
Further, for improving the sealing effect of seal ring further, described seal ring outer ring is at least arranged a circle projection, described end cap inwall offers at least one circle groove accordingly.
As preferably, described number of slugs is two, and projection cross section is circular arc, and described groove surface is circular arc
The beneficial effects of the utility model are, the utility model with the addition of pressure ring arrangements on original speed reducer, and on end cap and seal ring, done further improvement, the sealability of speed reducer is obviously better than the sealability of traditional speed reducer, thus prevents the problem of leakage of oil.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model high leak tightness gearbox structure schematic diagram;
In figure: 1. casing, 2. end cap, 21. annular grooves, 22. hypotenuse two, 3. seal rings, 31. projections, 4. pressure ring, 41. protrude mounting end, 42. hypotenuses one.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
As shown in Figure 1, a kind of high leak tightness speed reducer, comprises casing 1, end cap 2, seal ring 3 and the pressure ring 4 for press seal circle 3; Described end cap 2 is arranged on the opening of casing 1, described seal ring 3 is arranged on end cap 2 inwall, the both sides of described seal ring 3 are the inclined-plane that outer ring width is less than inner race width, described end cap 2 exterior edge face offers the threaded annular groove 21 of tool, described pressure ring 4 has the threaded ring-like protrusion mounting end 41 of tool matched with annular groove 21 and annular groove 21 internal thread, described pressure ring 4 also has the annular hypotenuse one 42 corresponding with seal ring 3 ramp with seal ring 3 joint; Described end cap 2 inwall also have the annular hypotenuse two 22 corresponding with another inclined-plane on seal ring 3.The utility model with the addition of pressure ring arrangements on original speed reducer, and it can press seal circle further, thus makes speed reducer sealing effect better.For improving the sealing effect of seal ring further, described seal ring 3 outer ring arranges two circle projections 31, described end cap 2 inwall offers two circle grooves accordingly.The utility model with the addition of pressure ring 4 device on original speed reducer, and it can press seal circle 3, thus makes speed reducer sealing effect better.
The utility model with the addition of pressure ring 4 device on original speed reducer, and has done further improvement on end cap 2 and seal ring 3, and the sealability of speed reducer is obviously better than the sealability of traditional speed reducer, thus prevents the problem of leakage of oil.
