Tire building machine belt layer drum and radial expansion and contraction method thereof

轮胎成型机带束层鼓及其径向张缩方法

Abstract

The invention relates to a tire building machine belt layer drum and a radial expansion and contraction method thereof. A servo motor is adopted as an axial driving device; with motion mode conversion, drum tile radial expansion and contraction changes are caused with a mechanical transmission mode, such that the radial expansion and contraction distance of each drum tile can be precisely controlled. Therefore, belt layer drum diameter range adjustment precision can be improved. The belt layer drum radial expansion and contraction method comprises the steps that: at least a set of drum tiles which can be radially expanded and contracted, and a conical sleeve which can be subjected to synchronous axial rotation with the drum tiles are radially sleeved on a main shaft of the belt layer drum. A thrust device driven by the servo motor is axially arranged along the main shaft. The thrust device comprises a first push rod laterally connected with the conical sleeve. The first push rod rotates synchronically under the driving of the conical sleeve, such that the first push rod can push and pull the conical sleeve along an axial direction, and drum tile radial expansion and contraction can be realized.
本发明所述轮胎成型机带束层鼓及其径向张缩方法,采取伺服电机做为轴向驱动装置,通过运动方式转换以机械传动模式引起鼓瓦在径向方向上的张缩变化,从而实现精确地控制每一块鼓瓦径向张缩的距离,以及提高带束层鼓直径范围的调节精度。带束层鼓径向张缩方法是,沿带束层鼓的主轴径向套设有至少一组可径向张缩的鼓瓦、以及与鼓瓦可同步轴向旋转的锥形套。沿主轴轴向设置一伺服电机驱动的推力装置,推力装置包括一侧向连接锥形套的第一推杆,第一推杆在锥形套带动下同步地旋转,从而第一推杆可沿轴向推拉锥形套以完成鼓瓦的径向张缩。
