Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
It the present invention rather than limits the scope of the invention, after the present invention has been read, those skilled in the art are to of the invention each
The modification of kind equivalent form falls within the application range as defined in the appended claims.
As shown in Figure 1, a kind of gear grinding machines helical angle rotating shaft spring balance device, including Worm-gear assembly 3, worm screw 5, roll flute
Machine base 11, spring base group and groups of springs, Worm-gear assembly 3 and worm screw 5 are located in gear grinding machines, and Worm-gear assembly 3 and worm screw 5 match
It closes；Spring base group includes spring base I 1, spring base II 6, spring base III 7 and spring base IV 10, spring base I 1, spring base II 6, bullet
Spring abutment III 7 and spring base IV 10 are mounted on same perpendicular, and spring base I 1 and spring base III 7 are located at the perpendicular of Worm-gear assembly 3
The top of horizontal axis of rotation in straight plane and positioned at Worm-gear assembly 3, spring base I 1 and spring base III 7 are symmetrical with Worm-gear assembly 3
Vertical rotating shaft two sides, spring base II 6 and spring base IV 10 are located on roll flute machine base 11 in vertical surface and are symmetrical with snail
The vertical rotating shaft two sides of wheel assembly 3, spring base II 6 are located at the vertical lower of spring base I 1, and the spring base IV 10 is located at bullet
The vertical lower of spring abutment III 7；Groups of springs includes spring I 2, spring II 4, spring III 8 and spring IV 9, spring I 2, spring II 4, bullet
The both ends of spring III 8 and spring IV 9 are equipped with hook and performance is identical, and the hook of I 2 upper end of spring is fixed on spring base I 1, under
