A Novel Tool For Producing Externally Splined Sleeves

[Full Text]

Externally Splined Sleeves, Ballizing Technique, Process parameters, Forming rate and ball spinning.



The sleeves with external splines have an increased attention due to its use as power transmission parts in automotive, aviation, airspace, and machining equipment such as lathe, milling, and all equipment that have gear box. The manufacturing process of these sleeves by machining is expensive due to the consumed power, use of a special tool, and the material loss in machining. A new tool is proposed here to form the sleeves with external splines in one shoot. The new tool consists of a die with splines opposite to the required splines at its inner face. This die has a support for the specimen at the lower side and the specimen which has a longitudinal hole is fixed inside the die. A ball is forced inside the specimen hole to take the required sleeve shape by compelling the specimen inside the die cavities. The new tool is tested with different ball diameters to check the splines filling ratio. The forming process was conducted using a universal test machine and the forming load was recorded. The suggested process found to be successful.
