Problems solved by technology

Textbooks can only explain it theoretically, and it is difficult for students to intuitively understand the specific process of Fan Chengfa's gear machining
However, the transmission system of gear shaping machine tools for production is complex, and the mechanical transmission mechanisms are all enclosed inside the machine bed (box), which has poor visibility and is inconvenient for classroom teaching

Abstract

The invention relates to a gear shaping machine tool for teaching. The gear shaping machine tool is used for demonstrating the process of machining a gear in teaching by a generation method. A mechanical transmission system of a gear shaping machine is transmitted by a motor connecting belt or outputs power by manual, a main shaft is driven to rotate, move vertically and do cutter relieving motion by the mechanical transmission system, and a workpiece rotary table is simultaneously driven to rotate and do feed motion. The gear shaping machine tool has a simple structure and an appropriate size, is intuitive and convenient to operate, and can be used for deepening the understanding of a student on the working principle of making an involute-cylindrical gear by the generation method througha gear shaping experiment during teaching. Moreover, the student can also intuitively study various mechanical transmission devices.

Description

technical field [0001] The invention relates to a mechanical teaching experiment device, in particular to a gear shaping machine tool for processing involute cylindrical gears using the Fancheng method in teaching. Background technique [0002] Involute gears are the most widely used gears. At present, the most commonly used method in gear processing is the Fancheng method. It is processed according to the principle that when a pair of gears mesh and drives, the tooth profiles of the two wheels are conjugate curves. At present, the gear shaping machine tool is a typical machine tool that adopts the Fancheng method to process involute gears. [0003] Machining involute gears by Fan Cheng method is an important content of the courses "Principles of Mechanics" and "Mechanical Manufacturing Engineering", and it is also one of the difficulties in teaching. Textbooks can only be explained theoretically, and it is difficult for students to intuitively understand the specific proce...
