The invention relates to a mute rubber coating wheel which comprises a hub and a rubber coating ring, the hub is coated with the rubber coating ring, the mute rubber coating wheel further comprises a first elastic supporting frame, a second elastic supporting frame, two bearings and a locking piece, and the first elastic supporting frame and the second elastic supporting frame are spliced with each other and abut against the two sides of an inner rim of the hub respectively; a first annular gap is reserved between the first elastic supporting frame and the rubber coating ring, a first annular gap is reserved between the second elastic supporting frame and the rubber coating ring, the side faces of the sides, away from each other, of the first elastic supporting frame and the second elastic supporting frame are concaved inwards to form installation areas for installation of the bearings, and the two bearings are located in the two installation areas correspondingly and are coaxially arranged. The locking piece acts on the two bearings, so that inner rings of the two bearings tend to be close to each other, and a mounting channel allowing the rotating shaft to penetrate through is formed in the locking piece. The two bearings do not make direct contact with the hub, the buffering and damping effects of the idler wheel can be achieved through the first elastic supporting frame and the second elastic supporting frame, and therefore the mute effect of the wheel is improved.

    本申请涉及一种静音包胶轮,包括轮毂和包胶圈,包胶圈包覆在轮毂上,还包括第一弹性支撑架、第二弹性支撑架、两个轴承和锁定件,第一弹性支撑架与第二弹性支撑架相互拼接,且分别抵接在轮毂内轮圈的两侧,第一弹性支撑架与第二弹性支撑架与包胶圈之间留有第一环形间隙,第一弹性支撑架与第二弹性支撑架相互远离的一侧侧面内凹形成有供轴承安装的安装区,两个轴承分别位于两个安装区内,两个轴承同轴设置,锁定件作用在两个轴承上,使两个轴承的内圈具有相互靠近的趋势,锁定件上形成有供转轴穿设的安装通道。两个轴承不直接与轮毂接触,能够依靠第一弹性支撑架与第二弹性支撑架实现滚轮的缓冲减震效果,从而提高轮子的静音效果。
