Instrument for measuring oscillation backlash of bearing

Abstract

The invention relates to an instrument for measuring an oscillation backlash of a bearing, which comprises an operation hole segment and a mounting hole segment which are formed in a columnar instrument stand, wherein the operation hole segment and the mounting hole segment are coaxially formed and the inner end parts of the operation hole segment and the mounting hole segment are connected, so the joint of the operation hole segment and the mounting hole segment is shaped like a stage; the inner diameter of the mounting hole segment is more than that of the operation hole segment; two or more than two lock-screw holes are formed on the columnar instrument stand corresponding to the mounting hole segment; lock-screws are in threaded connection in the lock-screw holes; the inner end parts of the lock-screws extend into the mounting hole segment; a measuring hole is formed on the operation hole segment; the columnar instrument stand at the position of the outer wall of the operation hole segment is fixedly provided with a measuring dial-gauge; and a trigger bar is inserted into the measuring hole, the outer end part of the trigger bar is connected with the measuring dial-gauge, and the inner end part of the trigger bar extends into the operation hole segment. The instrument can precisely and visually measure the oscillation backlash of the bearing. The instrument has the advantages of simple structure, convenient measurement and the like.

Description

technical field [0001] The invention relates to a measuring device, in particular to a bearing swing clearance measuring instrument. Background technique [0002] In general, bearings have radial clearance and axial clearance requirements, such as figure 1 As shown, the internal clearance after the inner ring, outer ring, steel ball, and cage of the bearing are combined is usually called clearance in the industry. C-Dw>0, the axial clearance is called axial clearance, represented by Ga; the radial clearance is called radial clearance, represented by Gr. However, some users require that after the bearing and the shaft are assembled, the swing clearance meets the requirements, such as figure 2 shown. [0003] At present, the user can only use the swing gauge measuring instrument to grasp the bearing and shake the shaft to feel the size of the clearance. There is no accuracy and no data at all. Contents of the invention [0004] The purpose of the present invention is to...
