EV Spline-Coupling Grease: IOCL’s R&D Problem Statement, Translated
NLGI 2026 schedules IOCL R&D (Dr V. Manohar) on grease for EV spline coupling lubrication. Splines see sliding, fretting and temperature that a CV-joint moly grease only partly covers. This is a fretting + false-brinelling problem with an EV badge.

Literature/prior art for this note: NLGI Spokesman Sep/Oct 2026 — Vennampalli Manohar, IOCL R&D, grease for EV spline coupling. Read it as evidence under its own method, not as a formula you can paste onto an Indian CoA.

Lubechem will not invent a client list or a certificate. If the next step is a trial, send the duty brief. If the next step is legal clearance of a filing, that sits with a patent attorney.
What this page is for
India R&D + EV. Lets Lubechem sit next to IOCL in search without copying their work. Images are labelled conceptual illustrations. Patents and papers are cited so you can go read them.
What the paper is evidence for — and what it is not
| Paper says | Useful to a plant | Over-read |
|---|---|---|
| A mechanism or ranking under stated conditions | Adds a test or a caution to the brief | Not a drop-in Indian SKU |
| NLGI Spokesman Sep/Oct 2026 — Vennampalli Manohar, IOCL R&D, grease for EV spline coupling | Read the method section before the conclusion | Do not market the DOI on a drum |
| Limited speed / load / oil | Match your duty or discard | Do not scale a ball-on-disc to a kiln girth gear |
| Additive name or treat | A screening idea | Treat rates in papers are not commercial packages |
People-first note: this is dated editorial for decision-making. It is not a scaled rewrite of the manufacturing pages, and it is not legal or certification advice.
Questions plants actually ask
Is EV spline grease a drop-in for whatever we run today?
Almost never. Thickener family, base-oil viscosity, NLGI grade and additive response all have to be matched to the duty. A purge plan comes before a plant-wide switch. Compatibility charts are screens, not guarantees.
Can we put EV spline grease on the TDS because a patent or paper mentioned it?
No. Patents are prior art. Papers are evidence under stated conditions. A TDS line has to be backed by a method you actually ran, on oil you actually stock, at a treat you can buy twice.
Who owns the formula if Lubechem develops it?
Ownership is the contract. The practice is independent formulation with IP transfer as scoped — not a branded additive package you can never leave. Ask for the assignment language before the first kettle.
What should Indian EV drivetrain suppliers send in the first brief?
Duty (load, speed, water, temperature, relube), the current TDS and fail mode, target specs (IS / ASTM / OEM), and whether the product is sold, used in-house, or exported. Photographs of the failed component help more than adjectives.
