Dual-purpose gear generating instrument

Abstract

The invention provides a dual-purpose gear generating instrument. The dual-purpose gear generating instrument comprises a frame, a rack cutter, a support plate, a circular disk, a nut cap, a fixed disk, a gear cutter, a positioning plate, a driven gear and a slide carriage, wherein the slide carriage is arranged in a slide carriage sliding groove of the frame; the positioning plate is fixed above the frame; the slide carriage is provided with two gear support bars; the driven gear is inserted into the gear support bar on the lower side of the slide carriage; the gear cutter is inserted into the gear support bar on the upper side of the slide carriage; the gear cutter comprises a main meshing gear and a sectorial cutter; the main meshing gear of the gear cutter is meshed with the driven gear; and the tooth part of the sectorial cutter of the gear cutter is pressed on the circular disk. According to the dual-purpose gear generating instrument, the structure of the conventional gear generating instrument is improved, and students can perform rack cutter machining gear simulation tests and gear cutter machining gear simulation tests, so that the students can deeply understand rack cutter machining gears and gear cutter machining gears.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to a dual-purpose gear generator. [0002] Background technique [0003] The generating method uses the principle that when a pair of gears (or racks and pinions) mesh with each other, their conjugate tooth profiles are the envelopes of each other to process the gear teeth. During processing, one of the gears (or racks) is a tool, and the other One is the wheel blank, the two ensure a fixed angular speed ratio transmission, just like a pair of real gears (or rack and pinion) meshing transmission, at the same time, the cutter also performs cutting motion along the axial direction of the wheel blank, so the cut gear The tooth profile is like the envelope of the blade at various positions. If the involute is used as the tooth profile of the tool, its envelope must also be an involute. Since the process of forming the envelope of the blade at each position cannot be seen during actua...

[0007] However, this gear generation instrument, like the original gear generation instrument, can only carry out the simulation test of rack slotting machining gears, and cannot perform the simulation test of gear slotting machining gears. The principle of the simulation test is basically the same, so the applicant hopes to further improve the gear generation instrument, which can be used for the simulation test of the gear cutting tool processing by the rack and the simulation test of the gear cutting tool processing, so that the students can make a tool for the rack.
