Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 holds the schematic perspective view of sealing configuration for main shaft of boring machine that the utility model embodiment provides; Fig. 2 holds the plan view of the Rinsing unit of sealing configuration for main shaft of boring machine that the utility model embodiment provides; Fig. 3 holds the D-D face sectional drawing of the Rinsing unit plan view of sealing configuration for main shaft of boring machine that the utility model embodiment provides.
Composition graphs 1 to Fig. 3, first it should be noted that, the main shaft of boring machine that the present embodiment relates to holds sealing configuration and comprises the non-body that revolves and divide and solid of rotation part.
Described non-rotary body part is made up of bearing outer ring 108, headstock 109, seal ring 106, O shape circle 105 and labyrinth pressure ring 104; Described solid of rotation is made up of cutterhead 101, cutterhead and bearing connecting body 102, bearing inner race 107, labyrinth inner ring 103.Wherein cutterhead 101 is core work parts of development machine, and cutterhead and bearing connecting body 102 are links, and bearing inner race 107 and bearing outer ring 108 are driving components, and headstock 109 is the water channel that body supports part provides again Rinsing unit.
Seal ring 106 is arranged on headstock 109, damages bearing and pollution lubricating oil for preventing dust and rock particles from entering bearing bore.Rinsing unit mainly the layout of water irrigation channel and leak free design on headstock 109 and labyrinth pressure ring 104; also comprise O-ring seals 105; the Rinsing unit that main shaft of boring machine described in the present embodiment holds sealing configuration is the first line of defence that main bearing is protected; direct object of protection is seal ring 106, for preventing the foreign body intrusion such as dust and rock particles abradable seal circle 106.
The Rinsing unit that the main shaft of boring machine provided the present embodiment below holds sealing configuration is specifically described.
Particularly, in the present embodiment, the Rinsing unit that main shaft of boring machine holds sealing configuration comprises flushing hole; Described flushing hole is evenly distributed on the non-rotary body of described development machine.
In practical application, described flushing hole is evenly distributed within the scope of 270 degree, described non-rotary body top; Flushing medium in described flushing hole is water.Wherein, described non-rotary body comprises headstock and labyrinth pressure ring; Between described headstock and described labyrinth pressure ring, the described flushing hole place of communicating is provided with O shape to enclose.
Concrete, within the scope of the outer ring outer surface 270 degree of headstock 109, be uniformly distributed multiple radial flushing hole, optionally, the quantity of flushing hole can be determined according to the diameter of development machine, in the present embodiment, headstock 109 arranges 6 radial water flushing holes, and pipe thread is attacked in the aperture of 6 flushing holes; 6 flushing holes are met at the certain depth place of headstock 109 and are axially bored flushing hole to headstock 109 end face, be designed with 6 axial relay holes in the place that labyrinth pressure ring 104 is corresponding with headstock 109 flushing hole, 6 relay holes are met at suitable depth and are radially-inwardly drilled through.
Further, in order to anti-sealing leaks from headstock and labyrinth pressure ring surface of contact and reduces developing result, the place that flushing hole communicates between headstock and labyrinth pressure ring devises O shape circle.
The working procedure that the main shaft of boring machine that the present embodiment provides holds the Rinsing unit of sealing configuration is: the water source provided by water system is by the flushing hole access of six on headstock 109, labyrinth pressure ring 104 is entered by O shape circle 105 along the flushing hole on headstock, radially-inwardly going out the labyrinth entering labyrinth inner ring 103 and labyrinth pressure ring 104 formation again from pressure ring 104, finally carries dust and be discharged labyrinth together with rock particles.This prevents foreign matter and enter the sealing configuration that main shaft of boring machine holds, again owing to being aqueous medium and free from environmental pollution.
The technological scheme of the present embodiment, non-rotary body devises multiple flushing hole, and the quantity of flushing hole can be determined according to development machine diameter; Described flushing hole is evenly distributed within the scope of 270 degree, the top of non-rotary body circumference, water pipe from water system accesses from the tapped hole of headstock, hole on headstock passes into labyrinth pressure ring, finally enters labyrinth from labyrinth pressure ring, and the rock particles and dust that invade labyrinth are gone out labyrinth.In order to anti-sealing leaks from headstock and labyrinth pressure ring surface of contact and reduces developing result, the place that flushing hole communicates between headstock and labyrinth pressure ring devises O shape circle.Owing to have employed aqueous medium, the sealing configuration that the Rinsing unit that the main shaft of boring machine that the utility model is provided holds sealing configuration had both prevented foreign matter to enter main shaft of boring machine to hold, again reduces original oily medium to the pollution of environment.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristics; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment's technological scheme of the utility model.
