Internal Gear Pinion Drive
Internal Gear Pinion Drive (Product Code: SLE/MCE/80) is a hand-cranked bench-top model used to demonstrate the fundamentals of how an internal gear and pinion drive works in theory of machines and technical training classrooms. The gear train is left open for study between two clear plastic plates, and two dials show rotation so students can compare the movement of the gears. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Internal Gear and Pinion Drive Used For?
In an internal gear drive, a small pinion meshes with teeth cut on the inside of a larger ring gear. Unlike an ordinary external gear pair, both gears turn in the same direction and the centre distance is shorter, which is why the arrangement appears in planetary gearboxes and compact reduction drives. Turning the hand crank slowly lets students watch the teeth engage through the clear plates and see the same-direction rotation for themselves.
Using the two dials, the class can count turns and compare the result with the ratio of tooth numbers, then discuss why internal gearing gives a compact reduction. At 5 kg and 400 x 200 x 300 mm, the model is easy to carry between classroom and workshop, making it handy engineering educational equipment in India for ITI, polytechnic and first-year engineering courses. Wipe the plastic plates with a soft cloth so the mesh stays clearly visible.
OEM Manufacturer
This demonstrator is an OEM product. Jain Scientific Equipments Private Limited, trading as ScienceLab, manufactures the Internal Gear Pinion Drive at its own licensed factory at Saha, Ambala, Haryana, India, rather than reselling a bought-in model.
Training institutes, schools, dealers and importers order it directly from the manufacturer, which also handles repeat orders when more classrooms need the same model. Read more on the ScienceLab company profile.

Frequently Asked Questions
What does the Internal Gear Pinion Drive demonstrate?
The Internal Gear Pinion Drive demonstrates the fundamentals of how an internal gear and pinion drive works: a pinion meshing inside a ring gear, same-direction rotation of both gears, and the speed ratio shown on its two rotation dials.
How is the Internal Gear Pinion Drive operated?
The Internal Gear Pinion Drive is operated manually with a hand crank, so no electrical connection is listed. Students control the speed themselves, which makes it easy to stop at any position and examine how the teeth mesh.
What is the Internal Gear Pinion Drive made of?
The Internal Gear Pinion Drive is constructed from heavy duty metal and plastic. Its open gear system sits between two clear plastic plates on a base, so the working parts remain visible from both sides during a demonstration.
How big is the Internal Gear Pinion Drive?
The Internal Gear Pinion Drive measures 400 x 200 x 300 mm and weighs 5 kg. It is designed as a bench top or desktop item, so it needs no special stand or floor space.
Who manufactures the Internal Gear Pinion Drive?
The Internal Gear Pinion Drive is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. It is supplied factory-direct to institutions, dealers and importers.
Can the Internal Gear Pinion Drive be ordered for several classrooms?
Yes, the Internal Gear Pinion Drive can be quoted in multiple units for schools, training institutes and dealers in India and international markets. Send the quantity and destination through the contact page for a single consolidated quotation.
