BEARING CHOCK FASTENING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To prevent a fastening screw of a bearing chock from being loosened.SOLUTION: A bearing chock 1 has a main body 2 including a lower surface perpendicular to a vertical direction and two main body side surfaces 23 perpendicular to a transferring direction and has a flange 3 protruded from the main body 2. A bearing chock fastening part 51 has a bottom surface 511 perpendicular to the vertical direction and two inner wall surfaces 512 perpendicular to the transferring direction. A clearance is present between the lower surface of the flange 3 and an upper surface 54 of a table frame 5. The lower surface 22 of the main body of the bearing chock 1 is contacted with the bottom surface 511 of the bearing chock fastening part 51 in such a manner that it can be resiliently deformed in the transferring direction. There is a clearance between each of the two main body side surfaces 23 and each of the two inner wall surfaces 512 of the bearing chock fastening part 51, and an upper surface 34 of the flange part and a lower surface 55 of the table frame 5 are fastened by fastener screws 41.SELECTED DRAWING: Figure 3
