Title:
LINEAR MOTION GUIDE UNIT AND METHOD OF MEASURING LOAD OF LINEAR MOTION GUIDE UNIT
Document Type and Number:
Japanese Patent JP2022189279
Kind Code:
A
Abstract:
To provide a linear motion guide unit capable of further correctly determining a direction of a load applied to a casing.SOLUTION: A linear motion guide unit is equipped with a rail, a casing, a plurality of rolling bodies, a side face strain sensor, an end face strain sensor, and a pair of direction conversion members. The rail includes a pair of rail side rolling faces disposed on both sides in a width direction. The casing includes a casing body, and a pair of sleeve portions connected to both sides in the width direction of the casing body. The pair of sleeve portions is formed with a casing side rolling face forming a pair of rolling body rolling paths between the rail side rolling faces. The casing is formed with a pair of return paths penetrating the casing. The pair of conversions is formed with a direction conversion path connecting the rolling body rolling paths and the return paths. The side face strain sensor is disposed on the casing side face. The end face strain sensor is disposed on a casing end face that is an end surface of the casing in a longitudinal direction.SELECTED DRAWING: Figure 2
