Description
Technical field
The utility model relates to a kind of tangential elastic force analyzer, is specifically related to a kind of multiple-piece piston-ring tangential elastic force analyzer.
Background technology
Multiple-piece piston-ring is meant by two or many piston rings that accessory combines, for example the cast iron oil ring of support spring in the band, by firm band compound oil ring of scraping blade and grommet combination or the like.As control oil part important in the internal combustion engine, its tangential elastic force is the key factor of decision piston ring control oil effect.The compound oil ring elastic force assay method that is widely used at present is the clearance measurement method, its principle be with the oil ring correct installation to the elastic force support, be placed into earlier in the corresponding ring gauge with the thin slice clearance gauge and measure its gap; The ergometry that is applied is wrapped up it by artificial control again with flexible steel band, tighten up steel band and with the clearance gauge control gap; The artificial control of ergometry makes the gap identical with before, draws the elastic force value thus, and it is bigger that this method measurement result is influenced by human factor; And complicated operation, measuring error is bigger.So be necessary to develop novel measuring method and corresponding determining instrument.
Summary of the invention
The technical matters that the utility model will solve provides a kind of measuring error multiple-piece piston-ring tangential elastic force analyzer little, simple to operate.
For solving the problems of the technologies described above, the multiple-piece piston-ring tangential elastic force analyzer of the utility model comprises working plate, is fixed in the worktable on the working plate; Described worktable is provided with shaking device; Working plate is provided with upper and lower steel band seat, is provided with steel band between the upper and lower steel band seat, and the steel band bag circle that is arranged on the steel band places the shaking device top; The working plate below is provided with micromatic setting; Described micromatic setting comprises handle, the worm screw that is connected with handle, the worm gear that is connected with worm screw, the ball screw that is connected with worm gear, and force transducer is fixed on the worktable through line slideway, ball screw activity, and the one of which end is connected with following steel band seat; The other end is connected with clock gauge, also comprises the display that is connected with force transducer.
After adopting technique scheme; The utility model will place steel band bag circle with the calibrated bolck (its diameter is nominal cylinder diameter) that tested multiple-piece piston-ring is complementary earlier when measuring the piston ring tangential elastic force, open shaking device and make it vibrations; The adjustment micromatic setting makes steel band bag circle closely wrap up calibrated bolck; Record clock gauge reading S0, display reading F0, then tested multiple-piece piston-ring is placed steel band bag circle, it is S0 that the adjustment micromatic setting makes the clock gauge reading; Obtain display reading F1 this moment, and the difference of F0 and F1 is the multiple-piece piston-ring tangential elastic force.Use the utility model to carry out the multiple-piece piston-ring tangential elastic force and measure, because measurement data is not influenced by human factor, so measuring error is little, and simple to operate, and measuring repeatability is good.
