Problems solved by technology

Furthermore, piezoelectric sensors, i.e. sensors that generate a voltage under the action of an external load, are not suitable for measuring static stress
Its impedance is so high that the piezo voltage immediately breaks down when the piezo sensor is loaded with an ohmic load

Embodiment Construction

[0030] figure 1A cross-section of a linear rolling bearing 10 with a guide carriage 20 according to the invention is shown. In this case, the guide carriage 20 has four continuously encircling rows of rolling bodies 22 which are designed in the shape of rollers. A row of rolling elements 22 is provided on each raceway insert 30 . The linear rolling bearing 10 is constructed largely according to EP 2 110 571 B1, wherein in particular the raceway insert 30 is bonded to the main body 21 . The invention can also be used for guide carriages with ball-shaped rolling elements and for guide carriages without rolling element surrounds.

[0031] The number of rows of rolling elements can largely be chosen arbitrarily. For example, the invention can also be applied to linear rolling bearings constructed according to EP 2 949 954 B1. Here, ball-shaped rolling bodies are provided, wherein two rows of rolling bodies are assigned to each raceway insert. The raceway insert rests against ...

Abstract

The invention relates to a guide carriage (20) for use in linear rolling bearings, wherein said guide carriage (20) comprises individual rollers with carriage raceways (32) for rolling bodies (22) track insert (30). According to the invention, the raceway insert (30) is provided with piezoresistive layers (50) and electrodes (51) in order to measure external loads acting on the guide carriage (20).

Description

technical field [0001] The invention relates to a guide carriage according to the invention, which comprises a main body and at least one separate raceway insert, wherein on the base body of the raceway insert at least one Extended carriage raceways, wherein a row of rolling bodies is respectively assigned to at least one carriage raceway, said rolling bodies being able to communicate with the associated carriage raceway and the associated track raceway on said guide rail A rolling joint is provided in which the base body has at least one support surface via which the base body is at least indirectly supported in a force-transmitting manner on the main body. Background technique [0002] A linear rolling bearing with a guide carriage is known from DE 10 2008 051 682 A1. The guide carriage comprises several rows of continuously surrounding rolling bodies, wherein each row is supported in a load-transmitting manner on the main body of the guide carriage by means of associated...
