Embodiment
Below, based on accompanying drawing, embodiments of the present invention are described.
Fig. 1 and Fig. 2 represents that be fixed on the positioning fixed parts such as the bearings on the running shafts such as the main shaft being arranged on the High Rotation Speeds such as work mechanism, involved by the 1st mode of execution of the present invention locking nut.
This locking nut is, have on the nut main body 11 of the drum of the internal thread part 12 screwed togather with the external thread part of main shaft at inner peripheral surface, arrange from the through through hole 13 to inner peripheral surface of outer circumferential face at two places in a circumferential direction, spring bolt 14 is inserted in this through hole 13, after nut main body 11 and the external thread part of main shaft are screwed togather, to hold out against screw 15 is screwed in above-mentioned through hole 13, utilizing this to hold out against screw 15 makes the front end of spring bolt 14 nip the external thread part of main shaft, prevents nut main body 11 from loosening thus.
And, this locking nut equally spaced arranges multiple balanced adjustment tapped hole 16 in a circumferential direction on nut main body 11, main shaft is positioned on Equilibrator, measure the spin balancing of main shaft, and in the balanced adjustment tapped hole 16 of assigned position, be screwed into lock screw 17 as weight member, the adjustment of spin balancing can be carried out thus.
In the locking nut of the 1st mode of execution shown in Fig. 1 and Fig. 2, from the end face side of nut main body 1, configuring balanced adjustment tapped holes 16 at six places in the axial direction.
In addition, in the locking nut of the 2nd mode of execution shown in Fig. 3, be configured to the angle relative to the axis of balanced adjustment tapped hole 16 with 45 degree.
The 2nd mode of execution is as shown in Figure 3 such, if configure balanced adjustment tapped hole 16 angularly, then can from main shaft, use fixture to carry out adjustment balanced operation.In addition, if relative to axially configuring balanced adjustment tapped hole 16 angularly, then compared with the locking nut of the 1st mode of execution shown in Fig. 1 with Fig. 2, lock screw 17 as weight member can be changed apart from the distance in axle center, so, adjustment balanced capacity can be increased.
When relative to axially configure angularly balanced adjustment with tapped hole 16, this angle is not limited to 45 degree, can adopt arbitrary angle.
The engagement groove 18 that the outer circumferential face that the locking nut of the locking nut of the 1st mode of execution shown in Fig. 1 and Fig. 2, the 2nd mode of execution shown in Fig. 3 is also separately positioned on nut main body 11 engages with instrument (not shown) during tightening retaining nuts 10.
The feature of locking nut involved in the present invention is, utilize the plastic deformation of the balanced adjustment tapped hole 16 caused by lock screw 17, lock screw 17 as weight member is fastened and fixed in balanced adjustment tapped hole 16, thus, the lock screw 7 be screwed in balanced adjustment tapped hole 6 is not loosened.
In the 2nd mode of execution shown in the 1st mode of execution and Fig. 3 shown in Fig. 1 and Fig. 2, when lock screw 17 is screwed in balanced adjustment tapped hole 16, lock screw 17 is nipped balanced adjustment tapped hole 16, there is plastic deformation in balanced adjustment tapped hole 16, lock screw 17 and balanced adjustment tapped hole 16 are not firmly linked loosely, thus, by the top squeeze of the diagonal position circumferentially of the worm tooth of lock screw 17 in echelon, arrange to the outstanding portion that shoots 19, the both sides of axis.
At the top of worm tooth, if the lock screw 17 be formed to the outstanding portion that shoots 19, the both sides of axis is screwed in balanced adjustment tapped hole 16, then as shown in Figure 5, the two wall generation plastic deformations of balanced adjustment near the lowest point of the worm tooth of the internal thread of tapped hole 16, shoot portion 19 and shoot (the light blackboard of Fig. 5 divides) in balanced adjustment tapped hole 16.
As shown in Figure 5, the top due to the worm tooth of lock screw 17 is squeezed into trapezoidal, therefore, between the lowest point of the worm tooth of the top of the worm tooth of this trapezoidal lock screw 17 and the internal thread part of balanced adjustment tapped hole 16, forms space 21.When the portion that shoots 19 of lock screw 17 shoots in the wall of balanced adjustment tapped hole 16, even if produce the stripping powder 20 of balanced adjustment tapped hole 16, this stripping powder 20 is also incorporated in space 21.Therefore, when lock screw 17 is screwed in balanced adjustment tapped hole 16, is difficult to occur to peel off the again engaging-in of powder 20, can be easily screwed into lock screw 17.
But the balanced adjustment tapped hole 16 be formed on nut main body 11 can be processed to form by thread forming tap.When being processed to form balanced adjustment tapped hole 16 by thread forming tap, forming recess 22 at the balanced adjustment top of the worm tooth of the internal thread part of tapped hole 16, also can receive in this recess 22 and peel off powder 20.
Below, the 3rd mode of execution shown in Fig. 6 is, make the lowest point of the worm tooth of the internal thread part of balanced adjustment tapped hole 16 more shallow, the top of the worm tooth of lock screw 17 is made to shoot the lowest point of balanced adjustment tapped hole 16, thus, make the lowest point plastic deformation of balanced adjustment tapped hole 16, lock screw 17 and balanced adjustment tapped hole 16 firmly do not link loosely (portion that shoots 19 of Fig. 6 with light black represent).
In the 3rd mode of execution shown in Fig. 6, the internal thread part of balanced adjustment tapped hole 16 is formed in the degree of depth that two pitches are not disturbed with the screw thread of lock screw 17 from inlet side, and the lowest point making three pitches later is formed more shallow.By making inlet side be the degree of depth do not disturbed with the screw thread of lock screw 17, easily lock screw 17 is inserted in balanced adjustment tapped hole 16.
In addition, the balanced adjustment top of the worm tooth of the internal thread part of tapped hole 16 of 3rd mode of execution of removing shown in Fig. 6, forms space 21 between the lowest point of the worm tooth of the top of the worm tooth of the internal thread part of balanced adjustment tapped hole 16 and lock screw 17.When the worm tooth of lock screw 17 shoots the lowest point of balanced adjustment tapped hole 16, even if produce the stripping powder 20 of balanced adjustment tapped hole 16, this stripping powder 20 is also incorporated in space 21.Therefore, when lock screw 17 is screwed in balanced adjustment tapped hole 16, be difficult to occur to peel off the again engaging-in of powder 20, so, easily can carry out being screwed into of lock screw 17.
In the 1st ~ 3rd above mode of execution, iron type materials, such as JISSS400 can be adopted to form lock screw 17 and nut main body 11, but make the hardness of the hardness ratio lock screw 17 of the nut main body 11 of formation balanced adjustment tapped hole 16 low, easily make balanced adjustment tapped hole 16 plastic deformation.
In addition, if form black oxidation overlay film or manganese phosphate overlay film on the surface of the lock screw 17 making balanced adjustment tapped hole 16 plastic deformation, then when fastening lock screw 17, reduce with the friction factor of balanced adjustment with tapped hole 16, can link with comparalive ease.
