To achieve the above object, the utility model provides following technical solution: a kind of close tolerance seal transmission worm gear case
Body, including cabinet, the cabinet are equipped with several axis holes, and the inner wall of axis hole is equipped with sealing mechanism, and sealing mechanism includes setting
In on axis hole installation annular groove, be set to installation annular groove in sealing ring and be set to sealing ring and install annular groove between determine
Hyte part, sealing ring are equipped with adsorption tank, adsorb the trapezoidal shape of slot cross-section, and the slot inner wall of adsorption tank is in arc-shaped, and adsorption tank
Groove depth between 0.5-0.8mm.
By using above-mentioned technical proposal, cabinet is equipped with several axis holes, in order to improve mentioning to the sealing effect of axis hole
It rises, by being equipped with sealing mechanism on the inner wall of axis hole, and sealing mechanism is set as including the installation being set on axis hole
Annular groove, the sealing ring being set in installation annular groove and the positioning component being set between sealing ring and installation annular groove, pass through peace
It fills annular groove and cooperates sealing ring, will be fixed, then improve good between sealing ring and installation annular groove by positioning component
Limit effect is assembled, adsorption tank is further equipped on sealing ring, is set as by the adsorption tank of setting, and by adsorption tank
The slot inner wall of the trapezoidal shape in section, adsorption tank is in arc-shaped, and the groove depth of adsorption tank then improves suction between 0.5-0.8mm
Covered effect between attached slot and axis, and then ensure sealing effect between the two.
The utility model is further arranged to: the positioning component includes the locating piece being set in installation annular groove and sets
It is placed on sealing ring and locating slot compatible with locating piece, the groove width of the locating slot is gradually subtracted from notch toward slot bottom direction
It is small.
By using above-mentioned technical proposal, positioning component includes the locating piece being set in installation annular groove and is set to close
In seal and locating slot compatible with locating piece, by the cooperation between locating piece and locating slot, then improve sealing ring and
Assembly effect between annular groove is installed, and the groove width of locating slot is gradually reduced from notch toward slot bottom direction, then improves to fixed
The limit effect of position block, and then ensure good sealing effect.
The utility model is further arranged to: the outer wall of the cabinet is equipped with several cooling fins, the thickness of each cooling fin
It is gradually reduced from the connecting pin of cooling fin and cabinet toward another extreme direction, and cooling fin is equipped with several thermal vias.
By using above-mentioned technical proposal, the outer wall of cabinet is equipped with several cooling fins, by the cooling fin of setting, and
The thickness of each cooling fin is gradually reduced setting from the connecting pin of cooling fin and cabinet toward another extreme direction, improves heat loss
Speed, and cooling fin is equipped with several thermal vias, then increases the area of heat dissipation, and then ensures that good heat dissipation is imitated
Fruit.
Detailed description of the invention
Fig. 1 is a kind of schematic perspective view of close tolerance seal transmission worm gear cabinet embodiment of the utility model.
Fig. 2 is a kind of close tolerance seal transmission worm gear cabinet embodiment axis hole schematic cross-sectional view of the utility model.
Specific embodiment
A kind of close tolerance seal transmission worm gear cabinet embodiment of the utility model is described further referring to figs. 1 to Fig. 2.
A kind of close tolerance seal transmission worm gear cabinet, including cabinet 1, cabinet 1 are equipped with several axis holes 2, in order to improve pair
The promotion of the sealing effect of axis hole 2 by being equipped with sealing mechanism on the inner wall of axis hole 2, and sealing mechanism is set as wrapping
It includes the installation annular groove 30 being set on axis hole 2, the sealing ring 31 being set in installation annular groove 30 and is set to 31 and of sealing ring
Positioning component between annular groove 30 is installed, sealing ring 31 is cooperated by installation annular groove 30, is passing through positioning component for sealing ring 31
It is fixed between installation annular groove 30, then improves good assembly limit effect, be further equipped on sealing ring 31
Adsorption tank 310 is set as the trapezoidal shape in section, the slot of adsorption tank 310 by the adsorption tank 310 of setting, and by adsorption tank 310
Inner wall is in arc-shaped, and the groove depth of adsorption tank 310 then improves between 0.5-0.8mm and coats effect between adsorption tank 310 and axis
Fruit, and then ensure sealing effect between the two.
The utility model is further arranged to, positioning component include be set to installation annular groove 30 in locating piece 301 and
It is set on sealing ring 31 and locating slot 310 compatible with locating piece 301, by between locating piece 301 and locating slot 311
Cooperation then improves sealing ring 31 and installs the assembly effect between annular groove 30, and the groove width of locating slot 311 is from notch toward slot
