Internal circular arc tooth cutting tool

Abstract

The invention discloses an internal circular arc tooth cutting tool. The internal circular arc tooth cutting tool comprises a tool body and tool teeth distributed around the circumference of the toolbody; the tool teeth each comprise a front tool face, a main cutting edge and a main rear tool face; each front tool face is a plane, and the included angle between each front tool face and the vertical plane of the corresponding tool tooth in the spiral direction is a front angle; each main cutting edge is an intersection line of the conjugate face of the machined circular arc tooth face and thecorresponding front tool face; the main cutting edges and the machined circular arc tooth face are conjugate all the time in the tooth cutting machining process; each main rear tool face is a free curved face composed of a plurality of main cutting edges; the main cutting edges after the tool is subjected to cutter sharpening again and the machined circular arc tooth face are still conjugate; andthe top circle diameters of the main rear tool faces are gradually decreased from the front end of the tool to the rear, and a rear angle is formed. The internal circular arc tooth cutting tool is used for machining of RV speed reducer pin wheel housings and other arc inner tooth parts and has the beneficial effects of being free of theoretical edge form errors and constant in machining precisionafter re-grinding.

AI Technical Summary

Benefits of technology

This patented cutter used inside an electric power system includes two parts: one part called inner circular teeth that are designed without any errors or variations during manufacturing processes while another part called external ones with larger dimensions like wires. These tools work together on both sides of each wire section they've been worked upon. They also have small inclined surfaces at their ends where it works against other components such as bearings when rotating them. Overall, these technical improvements make this type of machine more accurate than existing designs.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the production of highly accurate robot joint components such as an actuator or reduction mechanism used on vehicles that require precise movement control due to their size constraints. Current methods involve expensive processes like milling or turning which have limitations in terms of machineability (precision) and productivity. Therefore, it would be useful if new techniques could replace these existing ways without compromising performance.
