Description
Technical field
The present invention relates to technical field of mechanical transmission, especially a kind of vector cycloid speed change applied to articulated robot
Unit.
Background technique
Currently, the transmission device for being applied to the elaborate servo mechanisms such as robot, precision machine tool, aerospace requires have high biography
Dynamic precision, high transmission stiffness, transmission ratio is big, and transmission efficiency is high, small in size, light-weight, and transmission return difference is small, and the rotation of rotating member is used
Measure the features such as small.In order to design the rotating device for meeting above-mentioned requirements, disclosed in Chinese patent one it is entitled " gearless
The application (CN86104457) of differential speed reducer " is machined with the disk of hypocycloid raceway using a pair respectively and is machined with epicycloid
The disk of raceway is the advantages of engaged transmission is secondary, and two disks are opposite and transmission steel ball is put into raceway, and cyclo drive is utilized in it, and
And steel ball energy shuttling movement.
In addition it in the CN102767600A announced in 2012, discloses a kind of using S shape cycloid groove and its built-in
Ball realizes the BS speed reducer to slow down, this technology does not need to realize speed change by gear or worm-drive, to a certain degree
On reduce the noise of speed reducer, improve transmission efficiency.
Notification number is that CN104964011A discloses a kind of crosshead shoe driving speed reducer for articulated robot, this
Item technology is also to be slowed down using transmission of the driving ball in motion profile to realize, reduces speed reducer to a certain extent
Noise improves transmission efficiency.
Application No. is 201610997116 .6, the application of entitled trailing type driving speed reducer is disclosed is rolled by transmission
Pearl, which is fixed on, on transmitting balls fixation hole, allows transmitting balls to move in the ball moving track of differential speed variator on output shaft,
It will not be displaced in motion process ball, guarantee speed reducer proper motion.
Earlier application application No. is 201810297804.0, the application of entitled vector cycloid speed changer is disclosed and will be rolled
Pearl, which is arranged in the cycloid groove of cycloid disc and the ball fixation hole of drive disk, carries out gear, wherein cycloid disc is fixed on machine
On body, drive disk is driven by input shaft, which formed by two transmission combinations.
In above-mentioned each open file, ball is to move in the slot of arc, and ball itself is rounded, so slot pair
The active force of ball is in all directions, therefore in speed-change process, plays the variable-speed unit of speed changing function in transmission process
There is only radial forces can also generate axial force, and the axial force is unidirectional axial force, so after working long hours, each portion
It is constantly squeezed in the axial direction between part, generates huge frictional force, variable-speed motor is caused to export unstable, stepping vibration, hair
The bad phenomenons such as heat is big, wear rate is high.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides the vector cycloid speed change lists that one kind will not generate axial force
Member.
