PURPOSE: To make it possible to reduce cost by manufacturing two symmetrical component parts of a sleeve separately as discrete parts and subsequently intercoupling these parts by joining. CONSTITUTION: After the two symmetrical component parts 1, 2 are separately manufactured, these parts are intercoupled along the symmetrical plane 3 thereof. The sleeve has a toothed rim 5 on its inside surface 4. The strength, tolerance and surface finishing required for a transmission technique may be attained by this stage. |
