THE MULTIPLE-ANGLE SHAFT

Abstract: The multiple-angle shaft is used in a process in which it transmits the power received from the driving shaft to the following shaft. A normal usual universal joint can be used below 30<o> at the normal speed, within 45<o> at the very low speed, and at high speed it can only be used under the condition of below 5<o>. But this invention can be used at any degree ( alpha <= 90<o>) regardless of high or low speed. And as the normal multiple-angle shaft, the shaft of this invention can be used as a basic power transmitting process; it is more economic and simple than the gear of direct power transmitting process and the chain and belt of indirect power transmitting process.

Description: DESCRIPTION Title of invention The multiple - angle shaft Thechnical field This invention is called multiple - angle shaft Back around art It is used in the process in which it transmits the power received from driving shaft. It is also possible to use this shaft coupling when these two shafts are meeting in any intersecting angle ( <t =90° ) In other words, althought the intersecting angle of these two shafts is varied during transmission of rotation power, it is an application of juornal crank mechanism which can be used regardless of the velocity. For example, the conventional universal joint is used below 30° at the ordinary speed and can be used with in 45* at the very low speed. That is when the high speed is required angle ( <* ) below 5 is desirable. Generally. It is used when is below 30 and can't be used when is over 45 Disclouser of invention But this invention has a merit that it can be used widely in any angle ( °t ^ 90° ) regandless of high, or low speed rotation even when the intersecting angle between two shaft varies. Futhermore when the angle beyong (<*>90 ) is required, it can be used in all angle (0° =<= 360° ) by combining two mechanism of more. Therefore the multiple - angle shaft can be used widely at the transmission device of rotation which the designer want to use. Finally the result of experimention the multiple-angle shaft convinced us that we can manufacture and use it. Brief description of drawings Let's explain this more detaily as fellow according to the appended photo. The structure of the multiple-angle shaft is that both ends of the primeshaft pipe (1) and passive shaft pipe (2) is devided into two parts, where, at each ends of the prime shaft pipe (1) and passive shaft pipe (2) , Journal case (3) is combined respectively. And also both shafts are connected to rotate the journal, which is an applieating of double crank that is put into the journal- case (3) . Because the torsion is occured at the journal when the prime shaft and passive shaft are about to rotate, pin bearing (5) is installed at the outward of center ring with the torsional. As we can see the photo 2, to reduce the load imposed on the rotating multiple-angle shaft and friction resistance of the weight as low as possible, journal case (3) performs as function of bearing and needle roller (7) is inserted into throught the clearance. Hence, needle roller (7) support to a journal so that the journal can do a good function on rotation speed. And spring (8) prevent the multiple-angle shaft from deflecting downward by winding it around, and sets the whole components in equilibrium. Spring (8) is a stationary and fixed part not rotating with the multiple-angle shaft. Industrial applicability According to the method mentioned above, we invented widely useful multiple-angle shaft which has merits that is can be not only of great help in designing the fundamental trans¬ mission device of rotation power but also be of effective and economical value.
