Abstract
The utility model relates to a bearing oscillating play measuring instrument which comprises an operating hole section and an installation hole section which are arranged in a columnar gauge stand. The operating hole section and the installation hole section are coaxially arranged. The operating hole section is connected with the internal end part of the installation hole section and thereby the joint between the operating hole section and the installation hole section is step-shaped. The inner diameter of the installation hole section is larger than the inner diameter of the operating hole section. Two or more than two locking screw holes are arranged on the columnar gauge stand corresponding to the installation hole section. Locking screws are screwed in the locking screw holes. The internal end part of each locking screw stretches into the installation hole section. A measuring hole is arranged on the operating hole section. A measuring dial gauge is fixedly arranged on the columnar gauge stand at the outer wall of the operating hole section. A trigger rod is inserted in the measuring hole. The external end part of the trigger rod is connected with the measuring dial gauge and the internal end part of the trigger rod stretches into the operating hole section. The utility model has the advantages that the bearing oscillating play can be accurately and intuitively measured, the structure is simple, the measurement is convenient and the like.
Description
Technical field
The utility model 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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of instrument for measuring oscillation backlash of bearing that can measure the oscillation backlash of bearing accurately and visually is provided
The technical scheme that provides according to the utility model, 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.
