The invention provides a guide wheel, a cable reel and a crane, and relates to the technical field of ship manufacturing. According to the guide wheel provided by the invention, when the guide wheel guides the cable, the wheel main body rotates around the axis to form rolling friction with the cable, so that compared with the prior art that the cable is guided by using sliding friction, the wear and deformation of the cable are effectively avoided, and the service life of the guide wheel is prolonged; and the situation that the production time is delayed due to shutdown maintenance of the cable reel and the crane applying the cable reel is also avoided. The concave part is jointly defined by the first end part and the second end part, and the cable can be pressed into the concave part so as to form interference fit with the concave part, so that the cable can be ensured to be always or basically in a linkage state with the guide wheel in the guiding process, and further sliding friction caused by slippage between the cable and the guide wheel can be avoided; therefore, the rolling friction provided by the guide wheel is always or basically effective in the process of guiding the cable.
本申请提供了一种导向轮、电缆卷盘及起重机,涉及船舶制造技术领域。根据本申请提供的导向轮,在导向轮引导电缆时,轮主体绕着轴线的旋转以与电缆之间形成滚动摩擦,相较于现有技术中利用滑动摩擦引导电缆而言,有效避免了电缆的磨损及变形,并提高了导向轮的使用寿命,也避免电缆卷盘以及应用电缆卷盘的起重机停机维护耽误生产时间的情况出现。利用第一端部和第二端部共同限定出凹部,由于电缆能够压入到凹部内,从而与凹部形成过盈的配合,能够确保电缆在引导过程中始终或者基本上与导向轮处于联动的状态,进而能够避免电缆与导向轮之间出现打滑而产生滑动摩擦,因此有利于确保导向轮提供的滚动摩擦在引导电缆的过程中始终或者基本上有效。
