Reeves Motodrives permit accurate manual or automatic control of speed to compensate for changes in consistency, density, viscosity, etc. I thought the belts would wear in a bit, so I temporarily removed the spring and set the belt tension without the spring. Please remember that safety standards have changed over the years and information in old manuals as well as the old machines themselves may not meet modern standards. Rexnord Right-Angle Gear Drives are application-engineered to minimize stress and wear and extend service life. That's right, all too many times has a spare component or unit been passed over and found a day late. Siemens 802d Parameter Manual File Name: Siemens 802d Parameter Manual.
It functions well from the point of view of sawing, but I don't like what I see when it is running. McMaster and many others sells these belts -- they are a standard item. So, for about the same effort as making step pulleys you can restore the vari-speed drive. See, for example, the Oliver 22-A and the. Of course, if the vari-drive in them has a horrible reputation I doubt it , then you are correct in distancing yourself from it. This is an intermittent load, not a mission critical situation, so even if the life expectancy is reduced, you may never see it fail. The belt can take a set and the Reeves pulleys can wear.
They provide the desired speed without interrupting production flow. For all I know, it could be the wrong belt on that thing causing the problems. It will likely list the belt by part number and not a size. Chances are it's the right size, but worn. I don't see much bouncing up and down, but the pulley oscillation is worse with greater tension.
So I would have to buy a new c-face motor, and a gear box as well as have step pulleys and a vfd to make this all work? Our purpose is to provide information about vintage machinery that is generally difficult to locate. Okay, there is more than one: I'll suggest half of what you don't want to hear. It may well just be that your belt is shot -- people sometimes try to adjust the speed without the drill press running; and any belt can wear. In many cases, simply cleaning and lubing the parts -- maybe replacing the belt -- may get things working just fine. The company was founded by Marshall Truman Reeves in 1869 as the Hoosier Boy Cultivator Co. Introduction to Reeves Variable Speed The variable speed drive has two broad functions in industry: 1 — To provide a complete range of speeds to enable optimum operation of individual machines or equipment. There are a lot of concerns with my proposal, including overhung load on that gear reducer output shaft.
Since it works, I will run it this way for a while and see what happens. It's a rockwell 70-600 I will never buy anything else with a reeves drive in it. I wouldn't consider less than 4 inches diameter for the smallest pulley, whether driving or driven. I can still use it as long as i'm running fairly slow. It sounds simple, but it is always the next step. You just have to measure yours.
It's about the same effort as switching the thing to step pulleys and will work just as well. Making a positive identification of the failed component is the crucial first step. This is an old post that was recently brought back from the dead. Member kPotter is in Arizona, and he has contacts in the used machine trade. That will lock the hole saw on soooo tight that you will feel realllly stoopid. Those requiring an odd part or obsolete industrial component can place a want ad just as easily, again, with no charge or fee.
Based on the size of the spring - it appears to match the drawings in the parts manual I have. Even without a parts diagram, things should be pretty obvious upon inspection. TomGood points, and I did backpedal a bit, to approx. We do not warehouse parts and components, but provide a means for perspective buyers and sellers to achieve their goals. I have tried several different tension settings without the spring from very tight to pretty loose. The variable pulley oscillates back and forth on the shaft when the saw is running.
It's a cogged belt and it says rockwell with a number printed on it. Yes, the cones float on a keyed bushing, are pushed together with a heavy spring, and pushed apart to change the speed with some sort of yoke. Practical Machinist is the easiest way to learn new techniques, get answers quickly and discuss common challenges with your peers. If you run the belt near the rim of one pulley it should be near the last bit of cone on the other. So I can't tell what exact belt it needs for the reeves drive. By many, it is still considered to be a website for collectibles and the like, but a quick search can actually reveal a different side to the 'bay.
My guess is that your unit is severely worn for you to hate it so much? Bearings are easy to rig up. When they fail, they can leave us stranded in a bad situation on the shop floor. When I buy my mill it's guaranteed to be a step pulley bridgeport with a vfd. There are options, however, nothing is ever easy. Reeves Motodrives allow for differences in capability of men and machines by providing the flexibility needed to speed up or slow down to meet changes in number of operators or match differences in skill between operators. I recall that Dave Kamp has created a Franken- Johansson radial arm drill, and he is gratified with its abilities, and he hasn't gotten around to moving the belt on the step pulleys.
All information regarding varidrive has been contributed by a community of industrialists. When I try to crank the speed up a little it will start howling and rumbling. I was hoping I could just oversize the motor and vfd and make it all work for drilling steel. The problem is that once you have gotten your nifty new product, the siemens 802d parameter manual gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging. Steve, I trust you didn't run a 60 Hz motor at 400 Hz. Adjustments to your system are possible when there is no other choice. About Us We are a technology based organization.
