Case Study: Reducing Noise in Steering Column Splines
Background
When it comes to automotive steering systems, the spline is responsible for accommodating the motion from the steering column as it moves separately from the vehicle’s suspension. Without the proper lubricant, this motion will cause drivers to hear a stick/slip noise. A leader in the production of advanced automotive steering, driveline, and automated driving technologies came to Nye in search of a lubricant that would eliminate a stick/ slip issue that they were experiencing within their steering column splines.
Challenge
- Can the lubricant reduce noise coming from slip/stick in steering column splines?
Solution
Fluorocarbon Gel 866
A PTFE thickened, light viscosity, synthetic hydrocarbon grease.
- Greatly reduces the stick/slip noise
- Rust-inhibited
| Product | Chemistry | Temp Range (°C) |
Oil Separation (24 hrs @ 100°C) |
Evaporation (24 hrs @ 100°C) |
|---|---|---|---|---|
| FLUOROCARBON GEL 866 | PAO/PTFE | -54 to 125 | 1.8% | 0.08% |
Results
Ultimately, the customer decided to go with Fluorocarbon Gel 866 after it performed in the desired temperature range, met their durability requirements, and eliminated the stick/slip noise. The customer has remained satisfied with the product’s performance within their steering column splines.
