Case Study: Reducing Noise in Steering Column Splines
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. In unlubricated systems, the steering shaft slides up and down the spline which causes friction and vibration that presents itself to a driver in the form of a stick/slip noise. This noise can impact how a driver perceives the quality of a vehicle.
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 the stick/ slip issue that they were experiencing within their steering column splines.
Turning Down the Volume
While every application is different, Nye has many proven solutions that we recommend to our automotive customers who experience common issues such stick/slip noises. Damping greases are often recommended to address noise issues as they reduce vibration and impart a smooth quality feel to almost any mechanical and electromechanical device.
Nye has four families of damping grease that are all non-melting, shear-stable, and plastic compatible. Damping greases are often used in automotive and have been formulated to suit a wide range of operating temperatures.
The Nye Solution
After consulting with the customer, Nye recommended that the company apply our damping grease Fluorocarbon Gel 866 to their steering column splines. This PTFE thickened, light viscosity, synthetic hydrocarbon grease is intended for instruments with gears and sliding movements such as those found in a steering column spline.
Fluorocarbon Gel 866 is compatible with plastic components and is also rust-inhibited to protect metal components from oxidation. With an operating temperature of -54 to 125°C, this grease extends the low temperature range requirement of -40°C set by automotive OEMs.
| Product | Chemistry | Temp Range (°C) |
Application Notes |
|---|---|---|---|
| FLUOROCARBON GEL 866 | PAO/PTFE | -54 to 125 | A light viscosity grease intended for instruments with moving plastic parts, gears and slides and lightly loaded mechanical applications where available torque is low. |
The customer was pleased with Fluorocarbon Gel 866 after it performed in the desired temperature range, met their durability requirements, and eliminated the stick/slip noise. The customer decided to use our lubricant in their steering column spline and remains satisfied with its performance.
