A Novel Radial Telescopic Tire Building Drum and its Kinematics Design

Abstract:

A novel radial telescopic tire building drum is proposed to meet the radial tire production requirements. After the discussion of the mechanical structure and transmission principle of this mechanism, the kinematics equations together with the formulas of contraction ratio and pressure angle are established. In order to optimize the characteristics of force-transfer, when taking the interference condition into consideration, a kinematics design method of this novel radial telescopic building drum is proposed, which can obtain the minimal value of mechanism maximum pressure angle and satisfy the demand of contraction ratio. The most important feature of this building drum is that the external shell is driven by the internal shell. Designer can derivative more design schemes by applying this transmission principle.
