Abstract
The utility model provide a kind of can the gear bending fatigue test fixture of alignment jig error automatically.Described first seaming chuck bottom is sphere, and described second seaming chuck top is sphere, and the sphere of described second seaming chuck matches with the sphere of described first seaming chuck; The shaft shoulder of described second seaming chuck is sphere, and matches with the sphere of described gland nut bottom inner surface; Described push-down head and gear contacts are divided into involute surface.Second seaming chuck upper and lower surface of the present utility model is sphere, can when fixture loads automatic load sharing, even if fixture or gear work in-process exist certain error, also automatically can regulate when stand under load, guarantee that the power be carried on gearing line is uniformly distributed.
Description
Technical field
The utility model relates to a kind of gear bending fatigue test fixture, is particularly useful for the repeated bend test that gear-type is spur gear.
Background technology
Gear is widely used in mechanical transmission structure, and the excellence of its manufacturing property and usability all can cause serious impact to the normal work of plant equipment.The fatigue property of gear is an important performance indexes of gear, and in the design and checkout procedure of gear, the repeated bend test of gear is also the work that must carry out.Current gear bending fatigue test mainly adopts monodentate or bidentate load mode, applies the position that pulsation is loaded in the upper bound, single gear tooth region of engagement point, until gear breaking lost efficacy by loading pressure head.The design of gear bending fatigue test fixture has very important impact to test efficiency and precision.Very loaded down with trivial details during the fixture clamping gear of usual gear bending fatigue test, and cannot the position of rapid adjustment gear tooth, the test period is increased, and conventional efficient reduces.
Be disclose a kind of gear bending fatigue test device in the Chinese patent of 20142066224.8 at application number, comprise push-down head, lower compression nut, seaming chuck, upper gland nut, bracing frame, back shaft, gland, changeable die, push-down head is fixed on fatigue tester by lower compression nut, changeable die is fixed by screws in the aperture at push-down head top, bracing frame is fixedly connected with push-down head, gear is fixed on back shaft, back shaft is placed in the circular hole that formed by bracing frame and gland, and fixed by bolt tightening, seaming chuck is fixed on fatigue tester by upper gland nut.This utility model is simple and reliable for structure, accurately can determine the position of load(ing) point, position once determine, without the need to adjusting fixture again in campaign; Changeable die is easy to installation and removal, is convenient for changing use.But the fixture of this utility model cannot regulate each other, once there is error in the manufacture process of fixture, error will exist always, cannot eliminate.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of can the gear bending fatigue test fixture of alignment jig error automatically.
For solving the problem, the utility model have employed following technical scheme:
A kind of gear bending fatigue test fixture, comprises the first seaming chuck, the second seaming chuck, push-down head, little round nut, gland nut, bracing frame, back shaft, gland; Described push-down head is fixed on by described little round nut with it leaving the bed of fatigue tester; Have circular hole bottom support frame as described above, described push-down head can penetrate circular hole by circular hole bottom, until the shaft shoulder of push-down head overlaps with circular hole lower surface, is fixedly connected with by push-down head with little round nut by the shaft shoulder with bracing frame; The sidewall of support frame as described above has semicircle orifice and locating slot; The sidewall of described gland has and the semicircle orifice of the radiuses such as support frame as described above semicircle orifice and locating piece; Described back shaft is placed among the semicircle orifice of the sidewall of support frame as described above, and limits it by the semicircle orifice of gland and move radially, and described gland is fixedly connected with the sidewall of support frame as described above by bolt; Described first seaming chuck bottom is sphere, and described second seaming chuck top is sphere, and the sphere of described second seaming chuck matches with the sphere of described first seaming chuck; The shaft shoulder of described second seaming chuck is sphere, and matches with the sphere of described gland nut bottom inner surface; Described push-down head and gear contacts are divided into involute surface.
Described first seaming chuck, the second seaming chuck and push-down head are the high hard alloy steel through quenching.
Second seaming chuck upper and lower surface of the present utility model is sphere, can when fixture loads automatic load sharing, even if fixture or gear work in-process exist certain error, also automatically can regulate when stand under load, guarantee that the power be carried on gearing line is uniformly distributed.
