Grab 3, described grab 3 is used for limiting described motor 1 in the axial movement installing in the hole.Above-mentioned driver, motor 1 is in high rotating speed
During operation, be connected to grab 3 on motor 1 can limiting motor 1 in the axial movement installing in the hole, it is to avoid there is play in it.
And the ejecting force that motor 1 produces also can be unloaded in motor fixing seat 2 by grab 3 it is ensured that the safety and stability of operation.
In the present embodiment, the first end of described motor 1 is connected on the diapire of installing hole, the second end of described motor 1
Stretch out from installing hole, described grab 3 includes connected extension 30 and pothook 31, it is solid that described extension 30 is fixed on motor
In reservation 2, described pothook 31 is connected on the second end end face of motor 1, is moved in the axial direction installing in the hole with limiting motor 1
Dynamic.Preferably, described grab 3 is two, and two grabs 3 are symmetrical arranged, and improve spacing reliability further.It is appreciated that
Ground, described grab 3 can also be plural arbitrary number, arranges according to actual needs.Card described in the present embodiment
Hook 3 is obtained by the core pulling of mould local, and motor fixing seat 2 is only provided with two mould core pulling holes, will not be to the knot of installing hole
It is configured to affect.
As shown in figure 3, the described installing hole of this enforcement is mounting hole, the profile of described motor 1 and the shape phase of installing hole
Coupling, with limiting motor 1 in the radial rotating installing in the hole, so can ensure that motor 1 in the six-freedom degree installing in the hole all
Limited.It should be noted that the shape of installing hole can also be the other shapes such as square, triangle or ellipse, only
Want energy limiting motor 1 in the radial rotating installing in the hole.Described installing hole is shoulder hole, and described motor 1 is fastened on ladder
