SHA-CG high precision actuators are a great alternative for direct drive motors. SHA-CG actuators offer direct drive motor performance in a compact, significantly lighter package. Ideal for high precision rotary applications such as indexing turn tables, the SHA-CG offers improved rotary positioning accuracy with surface runout less than 10 microns.

The SHA-SG is a hollow shaft actuator with a compact outer diameter and exceptional torque/volume ratio. SHA Series AC Servo Actuators provide high torque and highly accurate rotary operation. These servo actuators utilize Harmonic Drive® precision gears combined with a brushless servomotor and magnetic absolute encoder. The SHA Series is an advanced version of the FHA series AC Servo Actuators, featuring a larger hollow shaft with a smaller, outside diameter.

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.

These hollow shaft servo actuators utilize Harmonic Drive® precision gears combined with a brushless servomotor and magnetic absolute encoder. The SHA Series features a large hollow shaft in a compact package. The SHA Series connects directly with Mitsubishi Electric’s MELSERVO-J4 SSCNETⅢ/H, see brochure.

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.
