Product overview | Integrated measuring system for BRS and RRS 7 Integrated measuring system IMS for ball and roller rail systems Rexroth ball rail and roller rail systems can be supplied with a completely integrated, inductive linear measuring system. The length measuring system consists of a scanner, a scale, reference marks, and the absolute code band. The Scanner with sensors is mounted on the runner block. As it travels over them, it evaluates the scale, the reference marks or the absolute code band integrated in the rail. This mechatronic system combines the functions of guidance and measurement...

Technical data | Integrated measuring system for BRS and RRS 9 General technical data and calculations of runner blocks Loads due to forces and moments on the runner block The forces acting on the system are distributed among the guiding wagons depending on the runner block. The loads due to forces and torques resulting from the effective forces need to be calculated for each runner block when performing the life expectancy calculation. All load calculations require an infinitely rigid mounting base and an infinitely rigid structure. The service life calculation for the IMS is performed in a...

Integrated measuring system for BRS and RRS | Technical data  Description and technical data of scanner (IMS-I / IMS-A) Scanner on the The basic design of the scanner is explained here, using a ball runner block as an example. runner block The scanner for roller runner blocks differs only in minor details. The scanner is mounted on the runner block via the adapter plate. It is no wider and no higher than the runner block. The mounting hole pattern of the runner block remains unchanged. Advantage: The mounting of the runner block on the adjoining structure remains the same even with a measuring...

Technical data | Integrated measuring system for BRS and RRS 11 Evaluation electronics The evaluation electronics contains all components for generating, processing, calibrating and transmitting signals. These signals are evaluated by external electronics (e.g. IndraDrive servo controller from Rexroth). To provide added protection, a front seal (1) is screwed onto the scanner. This prevents water, oil, cooling lubricant, shavings and dust from working their way into the scanner from the end face. The bottom side of the scanner is protected by longitudinal seals (3). Support plate The support...

Exceptions: Safety functions which do not rely on the encoder signals. Scanner mounting side The scanner mounting side defines the side upon which the reference edge (2, ) of the runner block is located in relation to the incremental scale (1) and the spacing T1 (3) of the guide rail when the scanner is mounted.
