MTSF
WORM AND WHEEL UNIT
The Worm and Wheel Unit “MTSF” allows to demonstrate the principle of a worm gear and to study the torque and to determine the efficiency and the
transmission ratio of a worm gear.
TENDER SPECIFICATIONS
Anodized aluminum frame, with panel in painted steel. Diagram in the front panel with similar distribution to the elements in the real unit.
The unit is self-contained and the wheel, worm and pulleys are mounted on ball bearings.
The unit includes:
Wheel:
Material: bronze.
Worm:
Material: steel.
Modulus: 4 mm.
Number of gears: 1.
Power transmission: 10.
The worm and wheel pair has a single start and a transmission ratio of 30:1.
Two pulleys:
Material: aluminum.
One pulley is located on the worm shaft (diameter: 40mm) to help to exert the effort to raise a load and the other pulley on the wheel shaft
(diameter: 120mm) to load the system.
Set of weights:
Weights on worm side:
1 x 50N.
1 x 20N.
2 x 10N.
2 x 5N.
It includes a 5 N weight holder.
Weights on wheel side:
1 x 5N.
4 x 2N.
2 x 1N.
2 x 0.5N.
It includes a 0.5 N weight holder.
Manuals: This unit is supplied with the following manuals: Required services, Assembly and Installation, Starting-up, Security, Maintenance and Practices
manual.
Dimensions: 400 x 400 x 800 mm. approx. (15.75 x 15.75 x 31.50 inches approx.).
Weight: 30 Kg. approx. (66 pounds approx.).
EXERCISES AND PRACTICAL POSSIBILITIES
1.- Learning the key variables and correlations of a worm gear.
2.- Learning the basic terminology of gearing (number of teeth, reference circle and axle base and modulus).
3.- Investigation of transmission ratio, torque, friction and self-locking.
4.- Experimental determination of velocity ratio.
5.- Comparison of the determined velocity ratio with the calculated value.
6.- Determination of effort with variation of load.
7.- Determination of friction with variation of load.
8.- Determination of efficiency with variation of load.
9.- Determination of limiting efficiency of the unit.
Optional:
- MTSF/CAI. Computer Aided Instruction Software System:
This complete software package consists on an Instructor Software (INS/SOF) totally integrated with the Student Software (MTSF/SOF). Both are
interconnected so that the teacher knows at any moment what is the theoretical and practical knowledge of the students.
INS/SOF. Classroom Management Software (Instructor Software):
The Instructor can:
- Organize Students by Classes and Groups.

WORM AND WHEEL UNIT
- Create easily new entries or delete them.
- Create data bases with student information.
- Analyze results and make statistical comparisons.
- Generate and print reports.
- Detect student’s progress and difficulties.
...and many other facilities.
This Software, working in network configuration, allows controlling all the students in the classroom.
MTSF/SOF. Computer Aided Instruction Software (Student Software):
It explains how to use the unit, run the experiments and what to do at any moment.
- This software contains:
Theory: gives the student the theoretical background for a total understanding of the studied subject.
Exercises: divided by thematic areas and chapters to check out that the theory has been understood.
Guided Practices: presents several practices to be done with the unit, showing how to perform the exercises and practices.
Exams: set of questions to test the obtained knowledge.
- MTSF/CAL. Computer Aided Learning Software (Results Calculation and Analysis):
This Computer Aided Learning Software (Results Calculation and Analysis) “CAL” is a Windows based software, simple and very easy to use,
specifically developed by EDIBON.
CAL is a class assistant that helps in doing the necessary calculations to extract the right conclusions from data obtained during the experimental
practices.
With a single click, CAL computes the value of all the variables involved and performs the calculations.
Also, CAL allows to plot and print the results. Within the plotting options, any variable can be represented against any other.
Available different plotting displays.
It has a wide range of information, such as constant values, unit conversion factors and integral and derivative tables.
