The purpose of this utility model can realize by following technical proposal:
The detachable worm gear of a kind of gear teeth, comprise rotating shaft and be set in disc-shaped body in this rotating shaft, the outer ring surface of described body is provided with the gear teeth of some even settings, the described gear teeth are obliquely installed along the axis of body, it is characterized in that, described body is provided with for the fixed base that the above-mentioned gear teeth is fixed on the body, described fixed base is two: first fixed base and second fixed base, has compressed part one on described first fixed base, has compressed part two on described second fixed base, the described gear teeth are positioned on the both sides of body and are respectively equipped with shoulder block one and shoulder block two, above-mentioned compressed part one is pressed on the shoulder block one, and above-mentioned compressed part two is pressed on the shoulder block two.
In the detachable worm gear of the above-mentioned gear teeth, described first fixed base is discoideus, described second fixed base is discoideus, described first fixed base and second fixed base lay respectively at the both sides of body, and described first fixed base and second fixed base are oppositely arranged, and described body is provided with the fastening structure that links together for first fixed base and second fixed base.
In the detachable worm gear of the above-mentioned gear teeth, described fastening structure has the screw rod of bar head for several, is arranged with nut on the body of rod of described screw rod.After installing, the bar head is resisted against on first fixed base, and nut is resisted against on second fixed base, after it is tightened, can reach the purpose that first fixed base and second fixed base are linked together.
In the detachable worm gear of the above-mentioned gear teeth, have the through hole of some even settings on the described body, above-mentioned screw rod is located in this through hole.
In the detachable worm gear of the above-mentioned gear teeth, described compressed part one is positioned at the edge of first fixed base, and described compressed part two is positioned at the edge of second fixed base.
Compared with prior art, the detachable worm gear of these gear teeth has the following advantages:
The reasonable in design of this worm gear, its gear teeth can dismantle, easy for installation, easy to process, reduced processing technology, cut down finished cost, reduced the wearing and tearing to machining tool, the installation precision height.
