Description
Technical field
This utility model relates to decelerator technical field, particularly relates to a kind of robot and slows down
Device.
Background technology
Decelerator plays coupling rotating speed between prime mover and working machine or actuator and transmission turns
The effect of square, decelerator is a kind of relatively accurate machinery, and the purpose using it is to reduce rotating speed,
Increase torque.At present, decelerator is as one of the core component of industrial robot, commercial production
In field, the application of industrial robot is more and more extensive, along with the development of industrial production technology, work
Industry robot has powerful market development prospect.But existing decelerator can not have higher
Bearing capacity, transmission accuracy is the highest and decelerator volume is bigger, it is impossible to be used on industrial robot
Come as driving means.
Utility model content
This utility model is in order to solve the problems referred to above, it is provided that a kind of robot decelerator,
This reducer structure is simple, volume is little, under same mechanism size, have bearing capacity big,
The feature that transmission accuracy is high, can be used on industrial robot as driving means.
Solve the technical problem that required by this utility model and can come by the following technical programs in fact
Existing:
A kind of robot decelerator, including power shaft, sun gear, planetary gear, described input
Axle is connected with sun gear, and described sun gear meshes together with planetary gear, and described planetary gear has three
Individual, three planetary gears are connected with Cycloidal Wheel by three eccentric shafts, described Cycloidal Wheel have two and
Position mutual deviation 180 °, the described Cycloidal Wheel gear teeth mesh together with the pin tooth of pinwheel, and described three
Eccentric shaft is connected through Cycloidal Wheel with output axillare, has output shaft to be connected with output axillare.
Further, between described Cycloidal Wheel and eccentric shaft, excentric sleeve is installed.
Further, capacity eccentric bearing axle is installed between described Cycloidal Wheel and excentric sleeve.
Further, described Cycloidal Wheel has the odd number gear teeth.
Further, output bearing is had to be connected with output shaft described in.
Further, described output bearing is taper roll bearing.
Further, the pin tooth of described pinwheel is the cylindrical gear teeth.
This utility model provides the benefit that: a kind of robot decelerator, this reducer structure letter
List, volume are little, under same mechanism size, have the spy that bearing capacity is big, transmission accuracy is high
Point, can be used on industrial robot as driving means.

8, pinwheel 9, output shaft 10, output bearing 11, output axillare 12.
Power shaft 1 is connected with sun gear 2, and sun gear 2 meshes together with planetary gear 3, OK
Star-wheel 3 has three, and three planetary gears 3 are connected with Cycloidal Wheel by three eccentric shafts 6, cycloid
Wheel has two to be respectively Cycloidal Wheel 7 and Cycloidal Wheel 8, Cycloidal Wheel 7 and Cycloidal Wheel 8 position mutual deviation
180 °, the gear teeth of Cycloidal Wheel mesh together with the pin tooth of pinwheel 9.Three eccentric shafts 6 are worn
Cross Cycloidal Wheel to be connected with output axillare 12, have output shaft 10 to be connected with output axillare 12.
In order to reduce friction, excentric sleeve 5, Cycloidal Wheel are installed between Cycloidal Wheel and eccentric shaft
And capacity eccentric bearing axle 4 is installed between excentric sleeve 5.For enabling power shaft to reach static balance
And the bearing capacity of just transmission is improved, Cycloidal Wheel has the odd number gear teeth.There is output bearing
11 are connected with output shaft 10, and output bearing 11 can be taper roll bearing.The pin of pinwheel
Tooth can be cylindrical wheel tooth.
This utility model robot decelerator, this reducer structure is simple, volume is little, in phase
With under mechanism size, have the advantages that bearing capacity is big, transmission accuracy is high, industry can be used in
Come as driving means in robot.
Of the present utility model ultimate principle, principal character and this practicality are more than shown and described new
The advantage of type.Skilled person will appreciate that of the industry, this utility model is not by above-described embodiment
Restriction, principle of the present utility model is simply described described in above-described embodiment and description,
On the premise of without departing from this utility model spirit and scope, this utility model also has various change
Change and improve, in the range of these changes and improvements both fall within claimed this utility model.This
Utility model claims scope and is defined by appending claims and equivalent thereof.
