X-Y System X-Y-Z System

The master X-axis transmission is shown fitted with a high precision planetary gearbox and a industrial servo motor. It is connected to the slave X-axis by a transmission shaft connecting between the output shaft of the first X-axis and the input shaft of the second X-axis by flexible couplings. The Y-axis transmission also has the same motor and gearbox arrangement fitted. It is connected to the carriages of the X-axes using the long fixing clamps which fit directly onto the carriage plate mounting holes. Both master X-axis and the Y-axis have a switch cam on the carriage and a system of two limit switches and a home switch fitted. The system illustrated is a logical extension of the basic X-Y system above. A short cantilever Z-axis is attached to the Y-axis to give controlled vertical motion. To minimize the moment load on the slides and bearings, the Y and Z-axes are connected directly by their carriages. In systems where the movement is rapid and the moving axes are not very long, the Y and Z-axes can use the lightweight beam to minimize the moving mass, and so improve dynamic performance.The cantilever Z axis is shown with the fitted planetary gearbox, which is well suited to the servomotor which is also shown. It is possible to back-drive this gearbox. If this is not permissible, then a brake motor should be specified. © Bishop-Wisecarver Corporation 2007. All rights reserved. www.bwc.com 888.580.8272 7
