Abstract

Wear strips have been used along the frames upon which robotic arms slide via ball bearings. These strips can be replaced when worn, and thus save replacing of the frame member or the whole frame. These wear strips tend to wear very fast, and thus have to be replaced quite often. One means of extending the life of these wear strips is to provide a secondary heat treatment, which hardens the material, thus lessening the wear rate.

Ball Work Hardening of High Yield Stainless Stell Wear Strips

Wear strips have been used along the frames upon which robotic arms slide via ball bearings. These strips can be replaced when worn, and thus save replacing of the frame member or the whole frame. These wear strips tend to wear very fast, and thus have to be replaced quite often. One means of extending the life of these wear strips is to provide a secondary heat treatment, which hardens the material, thus lessening the wear rate.

The new arrangement proposes using commercially available wear strip material. This commercially available material is a special high yield stainless steel with a low nickel content. These strips 10 are placed along the frame members 12, shown in Fig. 1, where the ball bearings l6 of the sliding joint 14 will ride. The ball bearing 16 will press into the wear strip 10 during initial operation of the arm along the frame member until a slight trough 18 is formed, as shown in Fig. 2. This trough will not only reduce the stress and end yielding of the wear strip, but at the same time work hardening occurs, increasing the hardness of the wear strip and, therefore, increasing the life.
