Device for measuring wear in large roller bearings
First Claim
1. An arrangement for measuring wear in large roller bearings, comprising:
- two bearing rings having an inner ring and an outer ring with a space for receiving rollers between said bearing rings;
indicator means for indicating a specific deflection between said rings;
probe means secured in an opening in said outer ring;
said probe having an end for contacting a surface of said inner ring, said inner ring having a groove with walls facing said probe, said end of said probe extending into said groove without contacting said walls of said groove;
said groove having surfaces located as far from said end of said probe as the maximum permissible depth of wear on said bearing;
said end of said probe being spaced from said walls of said groove for as long as wear on said bearing is less than said maximum permissible depth of wear;
said end of said probe contacting said walls of said groove when said permissible depth of wear is exceeded and becoming connected thereby to said indicator means;
said wear on said bearing being measurable in both radial and axial directions;
said probe means being adjustably secured in radial and axial direction in said opening in said outer ring.

Abstract
A device for measuring wear in large roller bearings that have two bearing rings (1 & 2) with space accommodating the rollers (3) between them. The device has an indicator that indicates a prescribed deflection between the rings and a probe (9) that is accommodated in an opening (10) in the outer bearing ring (2) with the end (11) of the probe able to come into contact with one of the surfaces of the inner bearing ring (1). The object is a device that will provide accurate and reliable indications of bearing wear even after years of use, that will be simple in design, and that cannot be damaged or destroyed by outside forces. The inner bearing ring accordingly has a groove (12) facing the probe, and the end of the probe extends into the groove. The surfaces of the groove are as far from the end of the probe as the maximal permissible depth of the wear on the bearing.
