DEVICE FOR MACHINING NON-CIRCULAR GEARS

Abstract

If at first the non-circular wheels were treated as a hobby subject, their use now becomes ever larger. They are used in robotics, replacing cam mechanisms and lever mechanisms in the textile and agricultural industries. The paper presents a device used for the processing of non-circular gears, a device made according to my own design. For machining non-circular gears, it is necessary to make a toothed wheel on a CNC machine after which, with the designed device, it is possible to proceed to the processing of an unlimited number of wheels identical to the original wheel, which we will call the reference. The device contains an operating rack that engages the reference wheel. The solid rack with the rack is mounted on the generator rack (tool). The two racks are fixed, with the indication that the tool performs both the main cutting movement and the intermittent radial feed motion. The reference wheel and the semi-manufactured wheel move together (jointly) in engagement with the two racks. Taking into account the variable radius of the wheels (reference and green), the device is provided with a system of guides that allow the generation process to be carried out. I appreciate that this device can be improved and adapted for machining non-circular toothed wheels with as many configurations as possible and with different gauges.
