Abstract
A gear shaping machine for elliptic gear is composed of slotting head, main body, bench, changegear group, slotting tool driver, speed variator, drive axle and gear linked to drive axle. Said bench has dual-eccentric sleeve structure. Said slotting tool driver uses involute planetary drive with less teeth difference. Its machining method features that the long axis and short axis of raw elliptic gear blank must be consistent to those of elliptic gear by regulating changegear. Its advantage is convenient machining.
Description
The invention belongs to machining equipment, relate in particular to the equipment of processing oval gear, also relate to method simultaneously with this equipment processing elliptic gear.
The advanced equipment of processing elliptic gear is to adopt numerical control gear milling or numerical control gear shaping both at home and abroad at present, and this process equipment costs an arm and a leg, the processing cost height.
It is cheaper to the purpose of this invention is to provide a kind of price, and elliptic gear process equipment easy to use provides the method with this equipment processing elliptic gear simultaneously.
The objective of the invention is to realize by the following technical solutions.
A kind of ellipse gear tooth pluging machine, comprise that plug, lathe bed, workbench, gear changing group, driven wheel slotting tool do the mechanism of rolling movement, gear and power transmission shaft and coupled gear, workbench links to each other with transmission mechanism, its workbench is two eccentric bushing structures, distance between workpiece installation shaft and outer eccentric bushing two center lines, more than or equal between the inside and outside two eccentric bushing center lines distance difference smaller or equal to distance between the inside and outside two eccentric bushing center lines and; The mechanism that the driven wheel slotting tool is made rolling movement adopts the involute planetary gear transmission; And to make the tie-rod of this transmission mechanism and the speed ratio of planetary gear be 2, and outer eccentric bushing equates with the angular speed of tie-rod; Be fixed with elliptic gear on the planetary gear, planetary gear is meshed with internal gear, and the distance of both center lines equals 1/2 of elliptic gear major semiaxis and semi-minor axis difference.
The workpiece installation shaft of workbench is equipped with interior eccentric bushing outward, and interior eccentric bushing is outer eccentric bushing outward, and the workpiece installation shaft is packed on the end of sliding cross coupling, and the other end and the power transmission shaft of this shaft coupling connect firmly, the central lines of center transmission shaft line and outer eccentric bushing.
