The reduction ratio of the second ring gear teeth or lobes to the roller meshing ring gear housing that is caused by eccentric motion is determined by the number of pins on the ring gear. This ratio is reliant on the eccentric motion that is taking place. In a similar vein, you'll find a more detailed explanation in the guide that I wrote before this one, and you'll also be able to view the 3D printing prototype that I developed for this guide. Now, for this particular iteration, I want to increase the reduction ratio, but at the same time, I want to reduce the size of the cycloid drive.
When it comes to the components for which I require tolerances that are more stringent than the standard tolerances, we have the option of selecting the surface roughness and tolerance that we want. When I placed the order for the components, I discovered that they arrived in a timely manner and were packaged with great care.
Between the front plate of the motor and the coupling, there must be a space that is at least 2 millimeters wide in order to meet the requirements. To fix the issue, all that is required is the application of two grasping screws. Now, let's take a look at these 20 rollers, which, when combined, will produce a reduction ratio of 19 to 1. The top surface of the bottom plate acts as the location for the housing for the gear ring and serves in this capacity.
I am the one who is to blame for this issue because I did not make any clearance or offset adjustments to the cycloid disc profile that was obtained from the parametric equation. In addition to that, I placed an order for discs that were treated with a powder coating, which resulted in the discs having an even greater diameter. On the other hand, I made up my mind to give CNC Machining Aluminum Parts a try and remove some of the materials from the disk, so I polished it with an instrument that rotates in a circular motion.
The disc can then be inserted, and the motor can be started so that we can watch how CNC Machining ABS interacts with the eccentric bearing and the ring gear roller after the disc has been inserted. This eccentric motion will now be transferred to the output shaft via the six holes that serve as the output shaft on the cycloid plate.
This will be possible once we have completed the previous step. After what seems like an eternity, we are finally in a position to set the cover on top of everything else and fasten it in place with six M6 bolts that are 45 millimeters in length each. The cycloid drive has arrived at the end of its assembly process at this point.
Another step that needs to be completed is mounting some thread inserts on the output shaft so that in the future we can connect a variety of components to the output shaft. Now that we have two cycloidal drives that are all set up and ready to go, CNC Machining Brass Parts is time to put them through some tests to determine how well they operate. Stay tuned for the first part of my analysis, which will focus on determining the torque that is generated by the cycloid drive.
A torque of about 450 n cm, despite the fact that one of the NC machining methods produces results that are both higher and more consistent. I designed this cycloid drive so that it is compatible with NEMA 17 motors as well as NEMA 23 motors. This allows it to be utilized in a wide variety of contexts. In order to successfully replace the motor, it is necessary for us to first disassemble a few components. The reading that I was given was somewhere in the neighborhood of sixty Newton. When expressed in terms of other units of measurement, the torque of approximately 3000 Newton cm, also written as 30 Newton meters, is quite impressive.
This is approximately equivalent to 34 Newton meters of torque. On the other hand, the value 2 has been assigned as the value for the rated position of this NEMA 23 stepper motor. To restate, is reasonable to estimate that the level of efficiency is somewhere in the neighborhood of 85%.
Due to an oversight on my part when I was placing the order for the powder coating, the disk profile is currently being handled manually. On the other hand, if we use a better bushing and machine the cycloid disk profile with the appropriate size and clearance, we will unquestionably be able to achieve better results. This is because there is no way that we won't be able to achieve better results. Naturally, the accuracy of the version that was printed with a 3D printer can also be improved by printing the cycloid drive with a higher level of precision. This can be done by printing the cycloid drive with greater precision.
