Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of screw rod drilling tool driving-shaft assembly of the utility model, forms primarily of O type circle 6, pad 7, disc spring sheet 8, bearing adjustable ring 9, housing 10, centralizer body shell 11, righting scapus 12, string bearing 13, bearing filler ring 14, lower TC O type circle 15, lower TC overcoat 16, lower TC inner sleeve 17, power transmission shaft 18 in upper TC inner sleeve 1, back-up ring 2, pin 3, upper TC overcoat 4, the outer O type circle 5 of upper TC, upper TC.Described string bearing 13 top is mainly provided with TC inner sleeve 1 and upper TC overcoat 4, back cushion sheet 7 and bearing adjustable ring 9 are located, string bearing 13 bottom is mainly provided with lower TC inner sleeve 17 and lower TC overcoat 16, locate by bearing filler ring 14 and lower TC overcoat 16, described housing 10 is threaded with lower TC overcoat 16, and described centralizer body shell 11 is threaded with housing 10.
Described pin 3 is placed in the cylindrical hole of housing 10, and upper end is provided with back-up ring 2.
Described housing 10 upper end is provided with taper thread, and middle and end portion is provided with common coarse thread.
Described disc spring sheet 7 has 4, and top and bottom are equipped with pad 7, and is placed between bearing adjustable ring 9 and housing 10.
Described centralizer body shell 11 is uniform-distribution with 5 projections, each projection is distributed with the small cylindrical opening of same number.
Described righting scapus 12 is placed in the small cylindrical opening of centralizer body shell 11 projection.
The lower end inner ring of string bearing 13 is fixed in described bearing filler ring 14 upper end, and bearing filler ring 14 lower end compresses lower TC inner sleeve 17.
