Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present utility model, and be described in detail, enablely understand function of the present utility model, feature better.
As Figure 1-Figure 2, be the torque limiter according to a preferred embodiment of the present utility model, this torque limiter comprises: the first main shaft 1, degree of tightness sheet 2, pad 3, tightening nut 4, the second main shaft 5, steel ball 6, spring 7, square toes 8, shell 9.
Wherein, the first main shaft 1 has the radial round plate 101 extended, and the cylindrical portion 102 of axially extending above and below round plate 101 respectively and cylindrical part 103.Wherein, round plate 101 also has eight the spring penetration holes 1001 be circumferentially evenly arranged, this round plate 101 also has two location penetration holes 1002; Degree of tightness sheet 2, pad 3 and tightening nut 4 successively through the cylindrical portion 102 of the first main shaft 1, and coordinate with the outside thread on cylindrical portion 102 surface.Bottom surface outstanding extension two locating columns 21 downwards of degree of tightness sheet 2, the free end of this locating column 21 inserts in two location penetration holes 1002 on the round plate 101 of the first main shaft 1.The top of cylindrical portion 102 also has the square hole be connected with torque input device.
Second main shaft 5 is coordinated with the first main shaft 1 in below by the cylindrical part 103 of the first main shaft 1, this second main shaft 5 has eight ball-and-sockets 51 corresponding with eight spring penetration holes 1001 on the first main shaft 1.A steel ball 6 is placed with respectively in each ball-and-socket 51.Steel ball 6 only has a hemisphere to be arranged in ball-and-socket 51, and another hemisphere is then arranged in the spring penetration hole 1001 of the first main shaft 1, and spring 7 is arranged in each spring penetration hole 1001 respectively, the bottom surface of one end and degree of tightness sheet 2 against, the other end then with steel ball 6 against.The body 81 that square toes 8 have cuboid shape and the flange 82 extended from its top radial direction, its body 81 extends from the below of the second main shaft 5 is outstanding, flange 82 is for being connected between the first main shaft 1 and the second main shaft 5, and these square toes 8 are for being connected with moment of torsion output unit.9, shell is sheathed on outside the first main shaft 1 and the second main shaft 5.In a particular application, shell 9 can be weldingly connected with the second main shaft 5.
In order to avoid friction produces abnormal sound, this torque limiter also preferably includes the first copper sheathing 10 between the upper limb of the round plate 101 being arranged on the first main shaft 1 and shell 7, and is arranged on the second copper sheathing 11 between the cylindrical part 103 of the first main shaft 1 and the second main shaft 5.
In the present embodiment, locating column 21 is two, is arranged symmetrically in the bottom surface of described degree of tightness sheet respectively, but is actually not limited to two, can also be other numbers.
In the present embodiment, described spring and steel ball are eight covers.But in other embodiments, can also be six covers, or ten covers, etc., specifically determine according to required torque size.The quantity of spring and steel ball is more, and the moment of torsion that can provide is larger.
According to a preferred embodiment of the present utility model, the using method of this torque limiter is as follows:
First, set the moment of torsion of this torque limiter, after determining torque safety cut off value N, with bench vice clamping square toes 8, rotate the first main shaft 1 with torque wrench simultaneously, adjust pine or tighten tightening nut 4, until torque wrench just can rotate and show value is N.
Then, anaerobic adhesive is spread upon on tightening nut 4, in the cylindrical portion 102 that anaerobic adhesive penetrates into the first main shaft 1 in thread gaps, tightening nut 4 is tightly binded at this screw thread place, now set moment of torsion and complete.
Then, consult shown in Fig. 3-Fig. 4, the square toes of pneumatic removable digital display type valve operator 200 are made to insert in the square hole on cylindrical portion 102 top of the first main shaft 1 of torque limiter, and fix with pin, the other end, then by the square hole of the square toes 8 insertion valve ABAP Adapter 300 of this torque limiter, fix with pin equally, the other end of valve ABAP Adapter 300 is connected with valve 400.
Finally, start pneumatic removable digital display type valve operator 200, valve operator 200 drives the first main shaft 1 of torque limiter to rotate, and is rotated, be further advanced by square toes 8 and be with movable valve ABAP Adapter 300 to rotate together with valve 400 handwheel by steel ball 6 and then drive the second main shaft 5.In this process, the first main shaft 1 and the second main shaft 5 and the relative non rotating of square toes 8.
When the output torque of pneumatic removable digital display type valve operator 200 is greater than the setting moment of torsion N of torque limiter, first main shaft 1 relatively degree of tightness sheet 2 rotates and produces displacement, the pressure that now spring 7 is subject to becomes large, and then stir steel ball 6 and jump out from a ball-and-socket 51 of the second main shaft 5, first main shaft 1 and then rotate relative to the second main shaft 5, steel ball 6 falls into next ball-and-socket 51 immediately, in this course, first main shaft 1 continues to rotate, steel ball 6 constantly jumps to another ball-and-socket from a ball-and-socket under the extruding of spring, second main shaft 5 stops the rotation, realize this torque limiter skid when input torque is excessive, thus cannot continue to drive valve ABAP Adapter 300 and valve 400 handwheel to rotate, play the effect of protection valve 400.
Above-described, be only preferred embodiment of the present utility model, and be not used to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Namely every claims according to the utility model application and description are done simple, equivalence change and modify, and all fall into the claims of the utility model patent.The not detailed description of the utility model be routine techniques content.
