Abstract
The invention discloses a kind of top and drive alignment bearing and oil sealing configuration structure under gear-box, comprise top and drive main shaft, carrying neck and lower alignment bearing and gear oil sealing and rotary seal, wherein, lower alignment bearing and gear oil sealing are arranged on the end of carrying neck, rotary seal is separated setting with swivel head, and rotary seal is installed on swivel head bottom as absolute construction.Lower alignment bearing and gear oil sealing move down by the present invention, be arranged on the end of carrying neck, rotary seal and suspension ring ABAP Adapter are provided separately simultaneously, thus improve bearing righting effect, alleviate the labor intensity of workman, shorten engineering time simultaneously, improve drilling progress.
Description
Technical field
The present invention relates to a kind of top and drive alignment bearing and oil sealing configuration structure under gear-box.
Background technique
As shown in Figure 1 to Figure 3, to drive the upper and lower alignment bearing spacing of main shaft less on top in the past, righting DeGrain.And lower alignment bearing 1 and gear oil sealing 2 are all positioned at the upper end of carrying neck, dismounting and change is very inconvenient, gear-box 3 need be opened, main shaft and carrying neck entirety propose, and can complete replacing task, waste time and energy, increase the labor intensity of workman, delay drilling time.
On the other hand, the oil circuit that hydraulic system is driven on tradition top is opened on carrying neck and suspension ring ABAP Adapter, and therefore rotary seal 4 must be positioned at swivel head, when suspension ring ABAP Adapter hangs drilling tool, extra extrusion stress can be caused to rotary seal 4, especially when two suspension ring load are uneven, when there is unbalance loading, particularly serious to the wearing and tearing of rotary seal 4, replacing seal ring is frequent, and change also inconvenient, swivel head 5 entirety need be unloaded, delay man-hour.
Summary of the invention
For prior art Problems existing, the object of the present invention is to provide and a kind ofly improve bearing righting effect, improve the top of drilling progress and drive alignment bearing and oil sealing configuration structure under gear-box.
For achieving the above object, alignment bearing and oil sealing configuration structure under gear-box are driven in top of the present invention, comprise top and drive main shaft, carrying neck and lower alignment bearing and gear oil sealing and rotary seal, wherein, lower alignment bearing and gear oil sealing are arranged on the end of carrying neck, rotary seal is separated setting with swivel head, and rotary seal is installed on swivel head bottom as absolute construction.
Further, the end of described carrying neck is the lower end of the carrying neck be positioned at below suspension ring ABAP Adapter.
Further, the bottom of described carrying neck is provided with uses bolted gland, and described lower alignment bearing and gear oil sealing are arranged on described carrying neck by gland.
Further, the below of described suspension ring ABAP Adapter is provided with described rotary seal, and described rotary seal is arranged on described carrying neck.
Further, described rotary seal is arranged on described carrying neck by described gland
Lower alignment bearing and gear oil sealing move down by the present invention, be arranged on the end of carrying neck, rotary seal and suspension ring ABAP Adapter are provided separately simultaneously, thus improve bearing righting effect, alleviate the labor intensity of workman, shorten engineering time simultaneously, improve drilling progress.

Embodiment
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.But the present invention can be presented as multiple multi-form, and should not be construed as the exemplary embodiment being confined to describe here.But, these embodiments are provided, thus make the present invention comprehensively with complete, and scope of the present invention is fully conveyed to those of ordinary skill in the art.
For ease of illustrating, here can use such as " on ", the space relative terms such as D score " left side " " right side ", for illustration of the element of shown in figure or the feature relation relative to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as the element being positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and space used here illustrates relatively can correspondingly explain.
As shown in Figures 4 to 6, alignment bearing and oil sealing configuration structure under gear-box are driven in top of the present invention, comprise top and drive main shaft 6, carrying neck 7, lower alignment bearing and gear oil sealing 8, rotary seal 9, suspension ring ABAP Adapter 10, gland 11.
Wherein, in the present invention, lower alignment bearing and gear oil sealing 8 mounting point of top being driven main shaft 6 move down, and lower alignment bearing and gear oil sealing 8 are arranged on the end of carrying neck 7, and the end of carrying neck 7 is the lower end of the carrying neck 7 be positioned at below suspension ring ABAP Adapter 10.By being moved down the position of lower alignment bearing and gear oil sealing 8, increasing the spacing of upper and lower alignment bearing, not only improving righting effect like this, and change bearing and gear oil sealing simple and convenient.
The bottom of carrying neck 7 is provided with bolted gland 11, lower alignment bearing and gear oil sealing 8 are fixed on carrying neck 7 by gland 11, when needs change bearing or gear oil sealing, only the bolted gland in bottom need be unloaded, more can change jobs, simplify the task of hard work originally.
The below of suspension ring ABAP Adapter 10 is provided with rotary seal 9, and rotary seal 9 is also arranged on carrying neck 7 by gland 11.The present invention adopts the mode of rotary seal 9 being separated with suspension ring ABAP Adapter 10, self-contained unit is made in rotary seal 9, it is arranged on suspension ring ABAP Adapter 10 lower end, which solves from unbalance loading problem during suspension ring ABAP Adapter lifting drilling tool, extends the working life of seal ring, cost-saving, and simplifying repair and replacement work, when changing rotary seal, unloading lower bottom part gland equally can finish the work, shorten engineering time, accelerate drilling progress.
