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.

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.
