Utility model content
The applicant, for the disadvantages mentioned above of prior art, carries out studying and improving, it is provided that a kind of simple in construction, good sealing effect, be prone to the closed-smelting machine rotor axle head mechanical sealing connecting device of part replacement.
In order to solve the problems referred to above, this utility model adopts following scheme:
A kind of closed-smelting machine rotor axle head mechanical sealing connecting device, including the mixing room wear ring being installed on armature spindle, quiet wear ring and rotary packing ring, rotary packing ring is installed on armature spindle by hot charging axle sleeve, on quiet wear ring, spiral is provided with softening oil inlet pipe, the end of described armature spindle is provided with spring seat ring and big nut, big nut spiral is installed on spring seat ring, the cylindrical hole of spring seat ring is provided with rotary packing ring against spring base, spring housing is placed on spring base and compresses anticreep by the spring washer of spring base end and spring press-cover；Being also equipped with the locating snap ring of holddown spring gland on described spring seat ring, locating snap ring is installed on spring seat ring by alignment pin locking and is compressed by big nut.
Further improvement as technique scheme:
Described spring seat ring is split type structure, and it is positioned by hollow pins and is fixed by the screw of both sides.
Of the present utility model have the technical effect that
Simple in construction of the present utility model, reasonable in design, seal reliable, in that context it may be convenient at production scene dismounting and change parts.
Accompanying drawing explanation
Fig. 1 is main sectional view of the present utility model.
Fig. 2 is sectional drawing of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Such as Fig. 1, shown in Fig. 2, the closed-smelting machine rotor axle head mechanical sealing connecting device of the present embodiment, including the mixing room wear ring 1 being installed on armature spindle 16, quiet wear ring 2 and rotary packing ring 4, rotary packing ring 4 is installed on armature spindle 16 by hot charging axle sleeve 19, on quiet wear ring 2, spiral is provided with softening oil inlet pipe 3, the end of armature spindle 16 is provided with spring seat ring 15 and big nut 14, big nut 14 spiral is installed on spring seat ring 15, the cylindrical hole of spring seat ring 15 is provided with rotary packing ring 4 against spring base 5, spring 6 is placed on spring base 5 and compresses anticreep by the spring washer 8 of spring base 5 end and spring press-cover 7；Being also equipped with the locating snap ring 13 of holddown spring gland 7 on spring seat ring 15, locating snap ring 13 is installed on spring seat ring 15 by alignment pin 12 locking and is compressed by big nut 14.
As shown in Figure 1 and Figure 2, quiet wear ring 2 fixed by the right side screw 9 of mixing room end wear ring 1, the right side built-up welding of quiet wear ring 2 alloy, and used on quiet wear ring 2 softening oil inlet pipe 3 threaded.The annular boss of the cannelure of armature spindle 16 and spring seat ring 15 is connected, armature spindle 16, spring seat ring 15 and rotary packing ring 4 have all driven keyway, spring seat ring 15 and rotary packing ring 4 are connected with armature spindle 16 by key 10, and rotate with armature spindle 16, key 10 screw 11 is fixed on armature spindle 16.Rotary packing ring 4 is enclosed within rotor hot charging axle sleeve 19, and seals with O-ring seals, the left side hardfacing alloy of rotary packing ring 4.Equipped with spring base 5 in the cylindrical hole of spring seat ring 15, spring 6 is enclosed within spring base 5, and spring press-cover 7 is enclosed within spring base 5 and holddown spring 6, prevents spring press-cover 7 from departing from spring base 5 with spring washer 8.
The left side of right side with rotary packing ring 4 in order to use quiet wear ring 2 forms end face rotational pressure and seals, equipped with locating snap ring 13 on spring seat ring 15, locating snap ring 13 alignment pin 12 is positioned on spring seat ring 15, big nut 14 is tightened on spring seat ring 15 by screw thread, and compress locating snap ring 13, locating snap ring 13 holddown spring gland 7, spring press-cover 7 holddown spring 6, spring 6 holddown spring seat 5, spring base 5 compresses rotary packing ring 4, rotary packing ring 4 compresses quiet wear ring 2, when armature spindle 16 rotates, rotary packing ring 4 and quiet wear ring 2 form reliable end force rotatory sealing.The degree that screws regulating big nut 14 can regulate the applanation between rotary packing ring 4 and quiet wear ring.
