Input gear axle is often longer, and the gear parts for so generally causing the input gear axle away from motor shaft end are running at high speed
When can perturb, and then influence robot transmission accuracy, particularly heavy load industrial robot, it is this perturb caused by
Have a great influence.
Utility model content
The purpose of this utility model is to provide a kind of joint transmission structure of industrial robot, by existing industrial machine
The transformation of person joint's drive mechanism, perturbing for input gear axle gear parts is reduced, reduce this and perturb to joint of robot transmission
Influence.To achieve these goals, the utility model adopts the following technical scheme that：
A kind of joint transmission structure of industrial robot, including housing, motor, input gear axle, RV reductors, bearing block
And bearing, the motor are arranged on housing, its output shaft is fixedly connected with input gear axle, the gear of the input gear axle
Part is meshed with the planetary gear of RV reductors, and RV reductors are fixed on housing, linking arm on the output shaft of RV reductors
Bar, the bearing block is arranged in input gear axle, and is fixed on housing, and bearing is provided with inside the bearing block.
Further, the bearing block center and input gear axle are coaxial.
Further, the pivot of the bearing and input gear axle are coaxial.

The transmission accuracy of high joint of robot, the raising to whole robot repetitive positioning accuracy play the role of it is very big, while to motor
With protective effect.
Brief description of the drawings
The Figure of description for forming the part of the application is used for providing further understanding of the present application, and the application's shows
Meaning property embodiment and its illustrate be used for explain the application, do not form the restriction to the application.
Fig. 1 is the joint transmission structural representation of existing industrial robot；
Fig. 2 is the joint transmission structural representation of the utility model industrial robot；
Wherein：1. motor, 2. input gear axles, 3. housings, 4.RV reductors, 5. gear shaft fixing screws, 6. reductors
Mounting screw, 7. bearing block mounting screws, 8. bearings, 9. hole back-up rings, 10. bearing blocks.
Embodiment
Utility model is described further below in conjunction with the accompanying drawings：
As shown in Fig. 2 a kind of joint transmission structure of industrial robot, including housing 3, motor 1, input gear axle 2, RV
Reductor 4, bearing block 10 and bearing 8, the motor 1 are arranged on housing 3, and its output shaft passes through gear with input gear axle 2
Axle fixing screws 5 are fixedly connected, and the gear parts of the input gear axle 2 are meshed with the planetary gear of RV reductors 4, and RV subtracts
Fast machine 4 is fixed on housing 3 by reductor mounting screw 6, and when motor rotates, input gear axle 2 can rotate, so as to drive
The output shaft rotation of RV reductors 4, armed lever, drive of the armed lever in RV speed reducer output shafts are connected on the output shaft of RV reductors 4
Lower rotation, the bearing block 10 is arranged in input gear axle, and is fixed on housing, and bearing is provided with inside the bearing block
8。
Further, the center of bearing block 10 and input gear axle 2 are coaxial.
Further, the pivot of the bearing 8 and input gear axle 2 are coaxial.
Further, inside the bearing block 10, the side of bearing is provided with hole back-up ring 9.
Further, the bearing block 10 is arranged on housing 3 by bearing block mounting screw 7.
When each inertia of the heavier loads installed on RV speed reducer output shafts is larger, the gear part of input gear axle 2 can be caused
Divide and perturb, to reduce perturbing for the gear parts of input gear axle 2, add bearing block 10 and bearing in bearing block 8, hole back-up ring
9, input gear axle 2 is supported on bearing 8, and when input gear axle rotates, the inner ring of bearing 8 follows rotation, and to input gear
Axle 2 plays certain supporting role, reduces perturbing for input gear axle gear parts, and then improves the transmission essence of joint of robot
Degree, while motor is played a protective role, the worst situation is that motor shaft perturbs, and the bearing of motor internal can be made to support
The bearing heating of motor shaft, the bearing can be damaged quickly.
It is not new to this practicality although above-mentioned specific embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
