The invention relates to a weighing wheel set, the weighing wheel set comprises a weighing sensing assembly, a wheel seat, a roller support, a shaft sleeve and a roller installed on the roller support, the weighing sensing assembly comprises a bearing seat, a weighing sensor, a bearing ball and a bearing shaft, the weighing sensor comprises an outer pressure bearing end and an inner stress end, the outer pressure bearing end is buckled with the bearing seat, and the inner stress end is buckled with the bearing seat. The inner stress end is suspended on the lower portion of the bearing seat, the bearing shaft is located under the inner stress end, and the lower portion of the bearing seat is connected with a ball retainer used for supporting and bearing balls in a floating mode. Due to the arrangement of the floating ball retainer, during weighing, the bearing balls are respectively in vertical contact with the inner stress end and the bearing shaft, so that the lateral component force of the bearing shaft is effectively reduced, the force vertically and upwards transmitted to the weighing sensor is maximally close to the weight of a borne heavy object, and the accuracy and repeatability of weighing are improved.
本发明涉及一种称重轮组,称重轮组包括称重感应组件、轮座、滚轮支架、轴套和安装于滚轮支架上的滚轮,称重感应组件包括承载座、称重传感器、承载滚珠和承载轴,称重传感器包括外承压端和内受力端,外承压端与承载座扣接,内受力端悬空于承载座下部,承载轴位于内受力端的正下方,在承载座的下部连接有用于浮动地支撑承载滚珠的滚珠保持架。由于设置浮动的滚珠保持架,在称重时,承载滚珠分别与内受力端和承载轴相互垂直接触,有效地减小承载轴的侧向分力,竖直向上传递给称重传感器上的力最大地接近所承受重物的重量,提高称重的准确性和重复性。
