Slip and Creep Measurement Apparatus
Product Code : LSK-TOMLE-10623
Slip and Creep Measurement Apparatus (SKU LSK-TOMLE-10623) is a flat-belt drive test rig for measuring belt slip, locating the creep zone and finding the friction coefficient between pulley and belt. Fabric, canvas and rubber belts can be compared under controlled tension and brake load. It serves Theory of Machines and machine design labs. The rig is manufactured by Science Lab Supplies in Saha, Ambala, India, and colleges, polytechnics and contractors order it from the factory itself.
Specifications
Motor, pulleys, belts and instruments of the slip and creep rig are split into single rows below. In short, a 1 HP, 1500 rpm variable-speed DC motor drives equal-diameter pulleys, a brake drum with spring balance loads the output, the driven pulley slides to set tension, and a two-channel digital RPM indicator reads both speeds.

Applications and Experiments for the Slip and Creep Measurement Apparatus
At fixed belt tension students increase the brake load, record both pulley speeds and plot (T1 − T2) against percentage slip to find the creep zone. Repeating at other tensions gives the tension characteristic, power transmitted and the point where gross slip begins.
- Percentage slip at fixed tension and slip characteristics.
- Coefficient of friction between pulley material and different belt materials.
- Power transmitted at varied belt tensions; tension characteristics.
- Belt slip speed and the limiting value at constant speed when slip starts.
- B.Tech/B.E. Theory of Machines and diploma power-transmission practicals, following first belt and chain comparisons on the Drive Systems Kit.
- Brake loading: comparing the drum-and-spring-balance method with the band brake on the Turbine Dynamometer.
Standard Scope of Supply

Frequently Asked Questions
What is the difference between slip and creep in a belt drive?
Creep is the small speed loss caused by the belt stretching and relaxing as it passes from tight to slack side. Slip is gross sliding of the belt over the pulley once the load exceeds what friction can carry.
Which belts come with the Slip and Creep Measurement Apparatus?
Flat belts of fixed length in fabric, canvas and rubber are supplied, so students can compare friction and slip for three materials running on the same pair of pulleys.
Who makes this apparatus?
It is made by Science Lab Supplies at its own plant in Saha, Ambala, India, and the company prices it for colleges and contractors directly, without a reseller.
Why is a stroboscope included?
The stroboscope lets students check pulley speeds visually and observe the belt while it runs, as a cross-check on the two-channel digital RPM readings.
