Model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of detachable gear wheel is provided, rational in infrastructure, stable connection is reliable, and matching gap is little, when gear wear need be changed, direct replacing external teeth base, without the need to dismantling coupling shaft, convenience easy to maintenance, maintenance efficiency is high, saves maintenance cost.

For achieving the above object, the technical solution of the utility model is: detachable gear wheel, comprise gear, base cover, tapered sleeve, nut, plain cushion, tooth base established by described gear, apertured in the middle of described tooth base, excircle establishes uniform tooth, left end setting heart shelves, right-hand member establishes outer cone, put centered by hole and be outwards divided into split one, split two, split three, described split one, split two, after the merging of original position order is pressed in split three, be enclosed within base to put, hole covers axle shelves circumference, in the fixed groove established in centering shelves embedding fixed end, right-hand member proceeds to tapered sleeve, through hole is established in described tapered sleeve, the inner cone of described through-hole wall is inserted in outer cone, plain cushion is established in tapered sleeve exterior edge face, described nut screws in the outside thread of base cover and locks.

Further setting, the angle of described outer cone, inner cone is 15 degree.

Further setting, establishes attachment hole in described tapered sleeve, and described attachment hole inwall establishes keyway.

Further setting, working width when described gear is separated is not more than 0.1mm.

The beneficial effects of the utility model are: the setting of base cover, is beneficial to the gear of split, and connects with transmission shaft; The setting of axle shelves, is beneficial to split one, split two, split three centering; The setting of fixed groove, is beneficial to the centering shelves of radial fixed gear, simultaneously energy axial restraint gear; The setting of outer cone, is beneficial to peripheral hardware tapered sleeve, coordinates with inner cone, under the inside coupling mechanism force effect of end nut outside, gear and base being overlapped fixing reliably, when gear wear need be changed, directly changing external teeth base, without the need to dismantling coupling shaft, convenience easy to maintenance, maintenance efficiency is high, saves maintenance cost.
