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
The present invention relates to a kind of measurement mechanism, especially a kind of instrument for measuring oscillation backlash of bearing.
Background technology
Generally speaking, bearing has end-play and end-play requirement, and as shown in Figure 1, the internal clearance after the inner ring of bearing, outer ring, steel ball, the retainer combination is called play usually in the industry.C-Dw＞0, end play are represented with Ga end-play; Radial play is represented with Gr end-play.But after the customer requirements bearing that has assembled with axle, oscillation backlash met the requirements, as shown in Figure 2.
Present oscillation backlash table surveying instrument, the user can only be used to catch bearing, shakes axostylus axostyle and feels the size of play, and no precision can say that no datat can be sayed.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of instrument for measuring oscillation backlash of bearing that can measure the oscillation backlash of bearing accurately and visually is provided
According to technical scheme provided by the invention, described instrument for measuring oscillation backlash of bearing, be included in handle hole section and the mounting hole section offered in the column gauge stand, the handle hole section is coaxial setting with the mounting hole section, and handle hole section and mounting hole section inner end join, make handle hole section and mounting hole section junction present step-like, the internal diameter of mounting hole section is greater than the internal diameter of handle hole section, offer two or more lock-screws hole on the column gauge stand of corresponding mounting hole section, the axis in described lock-screw hole and the axis of mounting hole section are vertical setting, and the center of circle of the inner end in lock-screw hole is identical with the place end face distance of mounting hole section junction to the handle hole section, in the lock-screw hole, be bolted with lock-screw, the inner end of lock-screw stretches in the mounting hole section, on the handle hole section, offer measured hole, on the column gauge stand at handle hole section outer wall place, be fixed with the measurement dial gauge, in measured hole, be plugged with frizzen, the outer end of described frizzen is connected with the measurement dial gauge, and the inner end of frizzen stretches in the handle hole section.
