investigation of mechanical efficiency of gears

Description:

• The MT 173unit is used to investigate the functionality of different gears.
• The test stand consists of a drive unit and a brake unit.
• Four different gears are available as accessories.
• Driving and braking power are calculated to determine the efficiencies.
• The components used are common in drive systems and therefore have a high level of practical relevance.
• A three-phase motor with variable speed via frequency converter serves as the drive unit.
• An air-cooled magnetic particle brake is used as the brake unit.
• The constant braking effect can be very finely adjusted via the exciting current; it then serves as a tuneable load.
• The following gear types are available separately as accessories: spur and worm gear, spur gear, bevel gear and planetary gear.
• Jointed shafts connect the gears to the motor and brake.
• Motor and brake are attached to a fixed torque sensor in order to determine the torques.
• The speed of the motor is detected contact-free by means of inductive sensors and is displayed digitally.
• The trainer is controlled by the PLCvia touch screen.
• By means of an integrated router, the trainer can alternatively be operated and controlled via an end device.
• The user interface can also be displayed on additional end devices (screen mirroring).
• Measured values are graphical represented on the user interface.
• Via the PLC, the measured values can be stored internally.
• Access to stored measured values is possible from end devices via WLANwith integrated router/ LAN connection to the customer’s own network.
