Background technology
Speed reducer is the independent type closed driving device between prime mover and working machine, is turned for reducing rotating speed and increase
Square, to meet need of work.Speed reducer is turned the higher rotation speed of input shaft by transmission parts (generally gear or worm screw)
Become the relatively slow-speed of revolution of output shaft.
When speed reducer works, output shaft is connected with execution unit, and input shaft is connected with motor shaft, and input shaft
Be sequentially connected between output shaft by transmission parts (such as planetary reducer, transmission parts be the sun gear that is meshed and
Planetary gear), so as to fulfill torque transmission of the prime mover (motor) between execution unit.
Existing speed reducer is general using the center that motor shaft is extend into input shaft when input shaft is with motor axis connection
In hole, then the bolt of unilateral setting is used to be locked, during bolt locking, the contact surface of input shaft and motor shaft occurs
Deformation and lead to discontinuity on periphery (because two peripheries can not be bonded completely), this unilateral stress can not only be made
Into the unstability of transmission, it can also aggravate the bounce of axis, influence transmission accuracy；Axis beat and transmission unstable phenomenon run at high speed it is lower outstanding
To be apparent, therefore its structure is further improved.
Utility model content
To solve the problems, such as that present technology exists, the utility model offer is simple in structure, and connection is reliable, and operating is stablized, biography
A kind of dynamic speed reducer input Axile connection structure with three-point fix with high accuracy.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of speed reducer input Axile connection structure with three-point fix, including being set to the motor shaft of motor center and subtracting
Fast machine input shaft, the motor shaft are inserted into the speed reducer input shaft, and the rear end of the speed reducer input shaft is fixed with
External jacket, the external jacket are placed on outside the motor shaft, and the external jacket is radially slotted and forms opening, on the external jacket
Opening is provided with screw, the inner circumferential radial convex of the external jacket is equipped with three locking bars, and three locking bars are uniformly arranged
In on periphery.
The technical measures of optimization further include：
Face aperture position opens up fluted on the external jacket.
The inner end of the locking bar is respectively arranged with the arc groove being adapted with the motor shaft outer diameter.
It cuts to form a plane far from opening side on the external jacket.
Cavity is provided on the external jacket, the head of the screw is embedded in the cavity, the screw
The bottom surface of head undersurface and the cavity mutually supports.
The speed reducer input Axile connection structure of the utility model, external jacket is fixed in the rear end of speed reducer input shaft,
And three locking bars being uniformly distributed on periphery are equipped in the inner circumferential radial convex of external jacket, form three using three locking bars
Point location structure, when screw lock, external jacket deforms upon, and three locking bars is made to securely fix motor shaft, so as to make electricity
It is formed and is reliably connected between arbor and speed reducer input shaft, simple in structure, connection is reliable, and operating is stablized, high transmission accuracy.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is structure diagram when external jacket clamps speed reducer input shaft.
Reference numeral therein is：Motor 1, motor shaft 11, speed reducer input shaft 2, external jacket 3, opening 3a, groove 3b,
Plane 3c, cavity 3d, locking bar 31, screw 4.
Specific embodiment
As shown in Figure 1 to Figure 2,
A kind of speed reducer input Axile connection structure with three-point fix, the motor shaft 11 including being set to 1 center of motor
With speed reducer input shaft 2, the motor shaft 11 is inserted into the speed reducer input shaft 2, after the speed reducer input shaft 2
End is fixed with external jacket 3, which is placed on outside the motor shaft 11, and the external jacket 3 is radially slotted and forms opening
3a, screw 4 is provided on the external jacket 3 at opening 3a, and the inner circumferential radial convex of the external jacket 3 is equipped with three lockings
Item 31, three locking bars 31 are uniformly arranged on periphery.
Face opening 3a positions open up fluted 3b on the external jacket 3.
The setting of groove 3b, under the premise of 3 integral strength of external jacket is ensured, during making the locking of screw 4, external jacket 3
Deformation be more prone to, so as to make the locking process of screw 4 more laborsaving, quick.
The inner end of the locking bar 31 is respectively arranged with the arc groove being adapted with 11 outer diameter of motor shaft.It utilizes
Arc groove when making 31 locking motor axis 11 of locking bar, has the effect of a automatic centering, such as between locking bar 31 and motor shaft 11
This, there is more centering effect when motor shaft 11 being made to be connect with speed reducer input shaft 2.
It cuts to form a plane 3c far from opening 3a sides on the external jacket 3.One piece of formation is machined away on external jacket 3
One plane 3c can not only mitigate the weight of external jacket 3, reduce generated rotary inertia during its rotation, and can avoid
Unilateral weight saving is caused when screw hole is set.
Cavity 3d is provided on the external jacket 3, the head of the screw 4 is described in cavity 3d
The head undersurface of screw 4 and the bottom surface of the cavity 3d mutually support.
This speed reducer inputs Axile connection structure, by being fixed with external jacket 3, external jacket 3 in the rear end of speed reducer input shaft 2
It dismantles and coordinates with speed reducer input shaft 2, facilitate the repair and replacement of external jacket 3, use cost can be reduced；And in external jacket
3 inner circumferential radial convex is uniformly distributed in locking bar 31 on periphery equipped with three, and three-point fix is formed by three locking bars 31
Structure, under the premise of securely locking is ensured, the raising that avoids setting excessive locking bar 31 and cause processing cost.
During connection, motor shaft 11 is passed through into external jacket 3 and is inserted into speed reducer input shaft 2, then lock-screw 4,
During screw 4 is locked, external jacket 3 deforms upon, and three locking bars 31 are firmly locked motor shaft 11, and make in motor shaft 11
Mandrel is located at the central shaft of speed reducer input shaft 2 on straight line always, the two is made to have good concentricity, so as to ensure
Transmission accuracy.
Embodiment of above is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with this skill
The people of art understands the content of the utility model and is implemented, and can not limit the scope of protection of the utility model with this, all
