Rotary table in market mainly includes 4 kinds of mechanism that is worm gear, roller cam, DD driver and harmonic structure. The following is the introduction:
1. worm gear: it’s one of the most popular structrue in NC rotary table because of its irreversibility and costs.The worm is generally made of bronze, but the wear resistance is poor. In order to improve the service life, some manufacturers use the alloy steel.
3.DD motor: it’s the most efficient rotary table with the highest precision. It has the highest precision because it has no mechanical structure, which is directly driven by motor , no reducer. It has high technical difficulty and high price. It is generally used for five axis machine tools.
4. Harmonic driver: Harmonic reducer is a new transmission structure in gear reducer. It uses flexible gear to produce controllable elastic deformation and cause relative staggered teeth between rigid wheel and flexible wheel to transmit power and motion. This kind of transmission is essentially different from the general gear transmission, and has particularity in meshing theory, set calculation and structural design.

At the beginning of the 20th century, industrial robots became popular in factories worldwide, especially in the automotive industry. With the continuous development of the robot industry, light-duty robots have gradually moved to every industry"s factory floor. However, the original RV gear reducers used by traditional large robots have gradually become inadequate because they cannot meet the needs of modern lightweight robots. New generation components made by companies like Leaderdrive have started to supplant the old RV gears. . . Machine assembly parts such as strain wave gears, rotary actuators, and frameless motors make up industrial robots" core components. These parts help production engineers to realize ideal motion functions without experiencing difficulties such as backlash and mechanical wear. The precision offered by strain wave gears and rotary actuators means that modern industrial robots can perform increasingly accurate micro-level actions.. .

Dynamic development of technology has resulted in the automation and robotization of not only manufacturing processes, but also many aspects of everyday life. A good example here is a device for neurorehabilitation, the prototype of which together with the results of its experimental examination was presented by Yamine et al. [1]. The device, equipped with two drives and transmissions providing a reduction rate of 49:1, was designated to support the process of rehabilitation in patients with physical motor disabilities, which made it difficult for them to carry out everyday activities. It is also worth mentioning other devices intended for operation in outer space or on other planets [2].
In view of the above, it is advisable to improve and adapt existing transmission designs and develop new ones, capable of meeting the sophisticated requirements demanded from modern drive systems. Such requirements include, among other things: high accuracy and precision in the transfer of motion; the possibility to obtain large transmission ratios at small overall dimensions of the gear; high efficiency; operability in extreme conditions (e.g., low temperatures [3]); and the overall high culture of drive train operation. The following may serve as examples of research projects aimed at the development of existing solutions:—
The use of duplex worm gears with an adjustable backlash in the joints of robot manipulator arms [4]. The paper presents the results of research on the improvement of motion transfer precision in the drive and minimization of vibrations which were obtained as a result of the reduction in play in meshing by means of the use of a special housing;
One of the newest design solutions in the area of transmissions for modern drive systems is the strain wave transmission, also known as the harmonic drive. The design, in view of its exceptional properties, is used in, among other things, drive trains of devices intended for operation in outer space [6]. The design solution was first patented in 1959 in the United States by C.W. Musser [7,8,9,10].
Among the main merits of harmonic drives, the following are most important:Smooth and silent operation which is a result of multiple-pair intermeshing where up to 50 pairs of teeth may be engaged at the same time;
The subject of the present study is a harmonic drive with a double-wave elliptical cam generator. For the assumed input quantities such as the load and contact geometry, the theoretical model proposed by Dowson and Higginson was used to determine properties of the elasto-hydrodynamic oil film occurring in meshing of toothed wheels. The results presented in this paper were obtained as part of a wider research project concerning the properties of harmonic drives.
I have tested rotary drives with both gear reducers and belt reducers. And while the gear reducers had sufficient holding torque the backlash was not acceptable. The belt driven reducers had very little backlash, but has very little holding torque.
The base plate on the harmonic drive does fit a little too tight for my tastes. You have to use the mounting bolts to pull it into place, and use a hammer to tap it back off. All my chucks have the same issue when mounted on this harmonic drive.
I plan on using the drive to mill four sides of a piece of square stock, and on my plasma cutter to cut features on both sides of a piece of steel angle.
I paid a little more for this drive ($150) as the seller was located in the states and had them in stock. I would have preferred a Sanou K12-100, but there was about a month lead time for them to arrive from China.
The drive is a little rough as the chuck key can be a little stiff as the jaws are tightened. It is loosening with use though, and It fits the harmonic drive. (like the others a little tight)
Is this $430 harmonic drive as good as a $2000 harmonic drive? No it is not. But I would not be willing to put a $2000 drive near my plasma torch. Once I get the drive connected to one of my CNC machines, I will run some repeatability and backlash tests.
The drive does exceed my expectations. I like that the drive has a generic 4” back plate with both 3 and 4 mounting holes. It is going to be fun trying out some new operations that I was not able to perform until now.
I don"t think he is talking about building a 4th axis from harmonic drive, but rather buying one already made for him. You can buy these on e-bay from China for about $400 with a 4" chuck. While not super cheap, it has the stepper motor mounted, and just needs an appropriate stepper driver. If you can get by with a smaller Sherline style lathe chuck, then you can get them for about $200.
If you don"t already have a rotary table then the cost is going to be at least as high unless you find a real deal on an RT, and then you probably need a chuck to go with it.
Harmonic drive bearing is cross roller structure.According to its application area there are two types one is our ring split and inner ring integraty another one is outer ring and inner ring all integraty.Rolling body are cylindrical rollers which arranged orthogonality,this structure can make one bearing can bear the load from every direction e.g. radial,axial and tilting torque etc. Bearing with high rigidity,rotation accurancy and load carrying capacity. This series bearing has compact appearance,with mounting hole,customer can mount directly,suitable for every kinds of harmonic drives.
Outer ring and inner ring are all integraty structure,mounting will have no affect on performance ,it can abtain stable running accurancy and torque.suitable for every kinds of SHF(SHG) series harmonic drives.
Bearing with high quality compound lithium-based grease in factory,so under normal using condition there is no need to add grease.but for bearing running ,in the inital stage ,the frictional torque will increase temporarily, frictional torque will be stable when grease uniformly adhere to raceway and roller.
