Worm Gears Unit are a category of helical rolling gears that are classified as transmission or conversion elements within machine elements. They are smaller and easier to operate than spur gears or bevel gears of the same performance and gear ratios. This type of gear comprises the usual driving worm and the driven worm wheel. Worm gears are quiet and have a damping effect.
Features:
Design and principle of worm gears.
Learning Objectives And Experiments:
Investigation of transmission ratio, torque, friction and self-locking
Development of the main variables and relationships in a worm gear
Determine the efficiency.
The flexible hoses connect to a small service console containing a water heater, reservoir, circulating pump and flowmeter. The flow and return temperatures of the heated water are measured together with the water flow rate which is also adjustable. The Water To Air Heat Exchanger Accessory includes a series connected copper tube bundle with flexible flow and return hoses that is designed to fit the aperture in the Cross Flow Heat Exchanger duct. This allows investigation of the heat transfer at various operating conditions.
Expermental Capabilities:
Determination of heat transfer rates of water and air together with the efficiency.
Determination of overall heat transfer coefficient and how this is affected by flow velocity.
The side walls of the experimental section are made of tempered glass, which allows excellent observation of the experiments. All components that come into contact with water are made of corrosion-resistant materials. The experimental flume with a closed water circuit has a cross-section of 309x450mm. The inlet element is designed so that the flow enters the experimental section with very little turbulence. The length of the experimental section is between 5m and with further extension elements a maximum of 12,5m.
Learning objectives/experiments:
Flow Transition (Hydraulic Jump)
Energy dissipation (hydraulic jump, stilling basin)
Flow over control structures
Together with optionally available models
Uniform and non-uniform discharge
Flow formulae
Flow-measuring flumes
Local losses due to obstacles
Weirs (sharp-crested, broad-crested, ogee-crested)
Discharge under gates
Sediment transport
Transient flow: waves
Vibrating piles.
A stainless steel hook or point is attached to the bottom end of the rod and is used to locate the water surface. A mounting frame is clamped to a suitable support structure and a gauging rod is free to slide up and down over the water surface.
Capabilities:
Measurement of slowly changing water levels in flumes and hydraulic models.
Location of air-water surface boundaries with high resolution.
Measurement of mechanical deformation.

Circuit Lab
The Circuit Lab with prototyping breadboard, power supplies and an universal connector as connections environment, is a low cost but ideal tool for learning.
Power Project Board
The Power Project Board with prototyping breadboard, power supplies.
A versatile Centrifugal Pump mounted on a trolley, for transferring liquids from one process to another.
A low rpm ensures that the liquid is not shaken.
The system is composed of a hardware unit and of a software for the analysis of the bus: through the analogue or digital modification of the values of the can module (by means of the software) it is possible to check how the system (hardware) reacts to errors. The System For The Study Of CANOPEN has been designed for the study of electronic systems with can bus architecture, based on CAN OPEN protocols. Thanks to the functions of the software, there are different possibilities for disturbing the input signal, so that it is possible to simulate the different situations of errors in the operation of an industrial machine.
General Features:
The system is composed of two sections, a programmable master control unit and a full CAN OPEN slave, and permits the realization of simple bench experiments: using the appropriate controls it is possible, in fact, to create simple applications and different simulations of the operation of the controller. The System For The Study Of CANOPEN is composed of a dedicated hardware and of a software interface. The connection between hardware and software is carried out via two can connections, connected to the doors can line A and can line B.
System For The Study Of CANOPEN is accompanied by a software that realizes the functions of protocol and data analysis: through the software it is possible to realize the function of fault simulation that allows simulating the different error situations that may occur in an automation network. The System For The Study Of CANOPEN is open to integration with any type of device with CAN OPEN interface; the device has a dual function of use as it can be used independently or in combination with other experiments, in which it replaces the traditional PLC. The programming of the master device, to realize the function of automation, is made with a suitable compiler.
This instructional kit provides the necessary material for students to learn systematically how a shaft is joined to a hub or a coupler in a professional way using taper keys. The material is clearly laid out on a plastic tray. We recommend that the exercises are carried out in a workshop, as all preparations such as filing, drilling, countersinking and tapping must be carried out in a correct and proper manner by the student. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.
