The mute wheel comprises a rotating column, the top of the rotating column is provided with a wheel frame supporting face, one side of the rotating column is provided with a wheel body, the wheel body comprises a hub and a wheel core, the wheel core is installed at the center of the hub, at least one side of the wheel core is provided with a bearing, the bearing comprises a bearing sleeve fixed to the end wall of the wheel core, and the bearing sleeve is sleeved with a bearing sleeve. The bearing and the bearing sleeve are made of plastic materials, a protruding ring piece is arranged on the end wall of the outer side of the bearing sleeve, a plurality of installation teeth are arranged on the outer side wall of the protruding ring piece, a first ball is placed between every two adjacent sets of installation teeth, a bearing outer ring is installed on the outer side of the protruding ring piece, and trundles are installed on the bearing outer ring. A plurality of rib position clamping pins are arranged on the side wall of the bearing outer ring, and a second ball is placed between every two adjacent rib position clamping pins. According to the mute wheel, the defects that an existing mute wheel adopts a hardware bearing, friction sound is large, sharp friction sound is likely to be generated, the mute effect is poor, and corrosion is likely to happen are overcome.

    本发明公开了一种静音轮,包括:旋转柱,所述旋转柱的顶部装有轮架托面,所述旋转柱一侧装有轮体,所述轮体包括轮毂和轮芯,所述轮芯安装在轮毂的中心处,所述轮芯至少一侧装有轴承,所述轴承包括固定在轮芯端壁的轴承套,所述轴承和轴承套采用塑料材质制成,所述轴承套的外侧端壁上设有凸出环件,所述凸出环件的外侧壁上布置有多个安装齿,相邻的两组安装齿之间放置有第一滚珠,所述凸出环件外侧装有轴承外圈,所述轴承外圈装有脚轮,所述轴承外圈的侧壁上布置有多个筋位卡销,相邻的两组筋位卡销之间放置有第二滚珠。本发明解决了现有的静音轮采用五金轴承,其摩擦声音大,容易发出尖锐的摩擦声,静音效果差、容易腐蚀的缺陷。
