Guest guest Posted March 20, 2000 Report Share Posted March 20, 2000 Having aquired a lorry axle and six speed gear box we are now preparing everything to sit tightly. although the axle could be buried into concrete thus supporting it sufficiently, this would mean any future movement would mean a major job. Radhe Syam has cot off one of the wheels at a distance of about 20cm from the differential. He wants to then build a frame to support the other wheel and dif' vertical. The gear box will be fitted directly onto the dif'. Cutting off one of the wheels means a metal plate will have to welded in its place to stop the oil from pouring out. The axle cost 100 pounds sterling. The gear box cost 100 pounds sterling and the propshafts cost 15 pounds sterling each. We are hiring a JCB to dig out the concrete foundations of the old power unit base. A new concrete base will be laid. The axle and frame will be bolted into the concrete.

Guest guest Posted March 21, 2000 Report Share Posted March 21, 2000 Dear Syam, Hare Krsna, I just wanted to let you know of some things that I've seen here. I've seen advertisment for small simple power units that used only one animal swing but could be implemented to many different uses. They were simple though and didn't require much power. As for doing things like cutting wood (logs), would require more power (oxen) and also heavier equipment, like the one here at Gita Nagari. This I think was one of the prime objectives to the design of this particular power unit. So It sounds as though you are planning simular heavy work for this unit you are building? There are other power unit failiers laying in the woods near the main power unit, one of which looks exactly the way you described the one your building. Balabhadra and I were looking at this thing about a week ago and he said that the dif. gears torqed out. Its a heavy duty axle with one end cut off and welded to a frame. Now it is sitting with the dif cover off of it and a heavy trans. sitting next to it (maybe also broke)?. The success came from the use of a cement trucks gear drive unit for the rotating tank. It has two gear reductions and the top gear is about 3.5 feet across and about 2.5 inches thick steel. The big gears are driven by chains. using it from the other end steps the RPM's if I remember right; around 600. then drive shafts, 2 long and 1 short connect to the next unit which steps the RPM's even higher then to a belt drive that goes to the cutting blade which turns at about 2000RPM. It has 5 swings on the turn. My concern with yours is hoping you don't end up with something not heavy enough for the way you were speaking.(6 teams) Also when ever you extend the drive shaft length, or have long shafts with a lot of force you increase the torque presure in the shafts which make it easier for them to twist or snap universal joints. And if you plan to have multiple gear step ups to maybe consider some type of flyweel some where on the higher end. So I hope this helps you in some way. yr servant, Derek, -GN- usa. *************************************** >"Syamasundara (das) (Bhaktivedanta Manor - UK)" ><Syamasundara (AT) pamho (DOT) net> >"Syamasundara (das) (Bhaktivedanta Manor - UK)" ><Syamasundara (AT) pamho (DOT) net>, Cow (AT) pamho (DOT) net >"Cow (Protection and related issues)" <Cow (AT) pamho (DOT) net> >Ox-power unit >Mon, 20 Mar 2000 18:17 +0000 > >Having aquired a lorry axle and six speed gear box we are now preparing >everything to sit tightly. > >although the axle could be buried into concrete thus supporting it >sufficiently, this would mean any future movement would mean a major job. >Radhe Syam has cot off one of the wheels at a distance of about 20cm from >the differential.
