Embodiment
In order more to be expressly understood technology contents of the present invention, describe in detail especially exemplified by following examples.
Example one
See also illustrated in figures 1 and 2, what Fig. 1 and Fig. 2 showed is a specific embodiment of mechanical slide formula angle super acceleration switching device of the present invention, comprise main shaft 1, bearing 2, casing 3, bearing 4, balancing disk 5, inertia dish 6, slide block 7, cover plate 8, extension spring 9, roller seat 10, travel switch 11 and roller 12, extraneous rotation is imported into by the described main shaft 1 that is installed in the described support, described inertia dish 6 is installed on the described main shaft 1 by described bearing 4 and constitutes revolute pair with main shaft 1, roller seat 10 is fixed on the main shaft, slide block 7 is installed in the groove of inertia dish 6 and cover plate 8 is installed, thereby slide block 7 constitutes moving sets with inertia dish 6, slide block 7 moving directions along main shaft 1 radially, extension spring 9 is installed between the adjacent sliders 7, roller 12 with slide block 7 identical effective quantity is installed on the roller seat 10, slide block 6 under the effect of extension spring 9 to shrinking near main shaft 1 direction and contact with roller 12 all the time, thereby the ledge portion of slide block 7 embedding travel switch 11 can away from stir travel switch 11 near main shaft 1 both direction.
When main shaft 1 beginning angle quickened to rotate, because inertia dish 6 is that revolute pair is connected with main shaft 1, inertia dish 6 began to rotate relative to main shaft 1 because of the existence of moment of inertia; And roller 12 is installed on the roller seat 10 that is fixed in main shaft 1, thereby roller 12 rotates relative to inertia dish 6; And slide block 7 can only move and can not rotate relative to inertia dish 6, thereby so roller 12 rotate relative to slide block 7 and promote slide blocks 7 toward moving away from major axes orientation; The power of extension spring 9 points to main shaft all the time and along with slide block 7 is increasing away from main shaft 1 direction displacement increases, when the power of 12 pairs of slide blocks 7 of spring 9 and roller equated, device reached balance point; The ledge portion of slide block 7 embeds travel switch 11, when slide block 7 displacements reach certain value, will trigger travel switch 11 actions, thereby travel switch 11 sends alarm signal; Otherwise, when main shaft 1 beginning angle slows down that speed is rotated and the power of 9 pairs of slide blocks 7 of extension spring during greater than the power of 12 pairs of slide blocks 7 of roller, slide block 7 will be toward moving near main shaft 1 direction, when slide block 7 displacements during greater than certain value, will no longer make travel switch send alarm signal.
Balancing disk 5 is fixedly connected with inertia dish 6, and balancing disk 5 can be regarded the part of inertia dish 6 as, increases or reduce the power that can adjust 12 pairs of slide blocks 7 of roller of balancing disk 5, triggers the required angular acceleration of travel switch 11 work thereby adjust; Adjust the power that the rigidity of extension spring 9 and initial length can 9 pairs of slide blocks 7 of extension spring, trigger the required angular acceleration of travel switch 11 work thereby adjust
