Generation of Involute Gear Tooth Profile
Product Code : LSK-TOMLE-10620
Generation of Involute Gear Tooth Profile (SKU LSK-TOMLE-10620) is a teaching board that reproduces how a rack-type cutter generates involute gear teeth. Students trace a tooth profile of module 25 mm onto paper for three gear blanks of different size and see how interference and undercutting appear. It serves Theory of Machines and machine design classes. Science Lab Supplies turns out the board at its Saha, Ambala manufacturing site in India and quotes colleges, polytechnics and tender contractors itself.
Specifications
Disc sizes, cutter and module of the involute board are given row by row below. In short, three white acrylic discs, A, B and C, with pitch circle diameters of 450, 300 and 200 mm work against a rack-type cutter of module 25 mm, and paper placed between disc and cutter records each generated profile.

Applications and Experiments for the Involute Gear Tooth Profile Board
The board is used to generate and compare involute tooth profiles on gears of three sizes cut by the same rack. Because the smaller blanks carry fewer teeth for the same module, the traced profiles show clearly when undercutting at the root and interference at the tip begin.
- B.Tech/B.E. mechanical, Theory of Machines: generation of involute profiles by a rack cutter.
- Machine design: effect of blank size on undercutting and interference.
- Diploma and ITI courses: understanding gear generation before seeing teeth indexed on the shop floor with a Universal Dividing Head on a Universal Milling Machine.
- Vocational training equipment for TVET mechanical drawing and gearing modules.
Standard Scope of Supply
Each board comprises the three white acrylic discs A, B and C of 450, 300 and 200 mm pitch circle diameter and the rack-type cutter of module 25 mm. Drawing paper for tracing profiles is a consumable supplied by the user, as is the pencil used to trace each position.
Packing, MOQ and Lead Time
You can ask for one board or several for a drawing hall or mechanisms lab, and the quotation will state packing, delivery time and price for that quantity. The companion Interference and Undercutting board and other units from this TVET lab equipment supplier can be added.

Drawing-hall and mechanisms-lab buyers can reach the company on the contact page, combine both gear boards in the enquiry cart, or go through the lab tender page for tenders.
Frequently Asked Questions
How is the involute profile generated on this board?
Paper is placed between a disc and the rack cutter, and the cutter outline is traced at successive positions as the disc rolls. The envelope of these outlines is the involute tooth profile.
Why are there three discs of different size?
The 450, 300 and 200 mm discs share the same 25 mm module, so they carry different numbers of teeth. Comparing their traced profiles shows how undercutting grows as the gear gets smaller.
Who manufactures the Generation of Involute Gear Tooth Profile board?
Science Lab Supplies makes the board itself in Saha, Ambala, India. There is no trading intermediary, so price and specification questions go straight to the team that builds it.
What are the discs made of?
All three discs are made of white acrylic, which gives a clean white background for positioning the drawing paper and seeing each profile traced with the rack cutter.
