Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-3, a kind of brushless motor governor, including governor body 1 and protection shell 3, protection shell 3 is top
Housing of the end equipped with opening, governor body 1 are located at the inside of protection shell 3, and the surrounding side wall of governor body 1 is equipped with four
A horizontally disposed limited block 4, four 4 array arrangements of limited block protect vertically disposed limit there are four being opened on the inner wall of shell 3
Position slot 5, limited block 4 are slidably connected in limiting slot 5, and the bottom end of governor body 1 is fixed with horizontally disposed fixed plate 7, Gu
The bottom end centre position of fixed board 7 is fixed with vertically disposed connecting pole 15, and the bottom end of connecting pole 15 is fixed on the bottom of protection shell 3
It holds on inner wall, connecting pole 15 is surrounded by four struts being obliquely installed 8, four 8 array arrangements of strut, the top of strut 8
It is hinged in fixed plate 7, the bottom end of strut 8 is hinged with sliding block 12, protects horizontal there are four being opened on the bottom end inner wall of shell 3
The sliding slot 14 of setting, four 14 array arrangements of sliding slot are in the surrounding of connecting pole 15, and sliding block 12 is slidably connected in sliding slot 14, sliding block
Horizontally disposed fixed link 10, side side of the sliding slot 14 far from connecting pole 15 are fixed on the 12 side side walls far from connecting pole 15
Horizontally disposed fixing groove 9 is provided on wall, the one end of fixed link 10 far from sliding block 12 is extended in fixing groove 9, fixed link 10
Outside is socketed with horizontally disposed first spring 11, and the both ends of the first spring 11 are separately fixed at the side wall of sliding block 12 and sliding slot 14
On, sliding block 12 is fixed with horizontally disposed elastic string 13 on the side side wall of connecting pole 15, and elastic string 13 is far from sliding block 12
One end be fixed on the side wall of sliding slot 14, the bottom end of limited block 4 is respectively and fixedly provided with vertically disposed second spring 6, second spring 6
Bottom end be each attached on the bottom end side wall of limiting slot 5, connecting pole 15 is hollow telescopic mast, and rubber is filled in connecting pole 15
Block, and the surrounding side wall of governor body 1 is equipped with cushion pad 2.
Operation principle:Governor when being worked normally to generate certain amplitude vibrations so that governor body 1 with
Shell 3 is protected mutually to squeeze, connecting pole 15 is squeezed at this time, due to the retractility of connecting pole 15, the rubber in connecting pole 15
Block is squeezed, while limited block 4 slides in limiting slot 5, and second spring 6 is squeezed, and rubber block is exchanged with second spring 6
The vibrations that fast device ontology 1 generates carry out snubber, this is level-one damping, and governor body 1 is mutually squeezed with protection shell 3 to be made
The bottom end for obtaining strut 8 is moved outward, and sliding block 12 slides in sliding slot 14 at this time, since sliding block 12 is to fixed link 10 and first
Spring 11 is squeezed so that fixed link 10 is moved into fixing groove 9, and elastic string 13 is stretched, due to 11 He of the first spring
The elasticity of elastic string 13 hinders strut 8 to move outward by sliding block 12, and the first spring 11 and elastic string 13 are to governor body
1 vibrations generated carry out snubber, this is two level damping, and cushion pad 2 carries out buffer protection to the side wall of governor body 1,
Governor body 1 and protection 3 mutual extrusion damage governor body 1 of shell are prevented, the present apparatus can carry out governor multistage
Damping reduces the vibration amplitude of governor, prevents the normal use of governor vibration amplitude larger impact brushless motor, damping effect
Fruit is good, and working efficiency is high.
