Spline shafts are important part of the rotating components. Typically in a gear mechanism, a male spline on the shaft matches with the spline on the female parts. There are ridges or teeth to transfer the torque. They also help in keeping the angular correspondence. Accuracy of spline shafts affects the efficiency of moving parts. Hence, it is important to buy shafts from standard Spline Shaft manufacturers in India. There are various types of shafts, but a few are widely used in various applications: Crowned splines Here, the teeth are symmetrical and the crown points towards the centerline where spline gets the maximum thickness. Since the thickness gets reduced gradually towards the ends, there is an extra thrust to the rotation. There are three categories of crowned splines; diameter fit, fillet and flat root. All of them are involutes with a male tooth which has crowns. In these shafts there are no crowns on the female part. Thickness at the pitch diameter denotes tooth thickness. Due to the difference of thickness, shaft tilts a little bit which causes a deeper penetration. Serration splines Valve shafts and instrument drives need a special type of splines that are known as serration splines. They are manufactured as per international standards like JIS or DIN. In these spline shafts, there are non-involute teeth with a simple included angle. Hence, it can accommodate more teeth in a smaller circumference. As a result, the rotation gets a larger area of contact. Female serration in these shafts has spaces with an equal included angle as there is in the mail detail. It is possible to order high quality serration spline shafts from Spline Shaft manufacturers in India online. There are product catalogues in the website and orders can be sent online. Helical Splines Helical splines can have involute teeth or parallel teeth. They are useful in a variety of applications where a high torque winds up straight spline shafts. Hence, a little bit of helix is given to it so that the winding gets distributed evenly. Since there is complete contact of teeth to the drive side, rotational torque gets distributed to a larger part of the shaft. As a result, there is less wear and tear and a greater efficiency. Due to helical teeth, thrust floats axially in the backward or forward direction according to the direction of rotation. A large number of Spline Shaft manufacturers in India make them by order because precision is highly important. The spline shaft manufacturers in India have plenty of opportunities to supply their products to automobile companies across India and abroad.
