The invention discloses an automatic centrifugal supporting wheel assembly of an automobile mixer, which comprises a supporting wheel, a supporting wheel main pin, a bearing and a bracket. The bearing is installed in the supporting wheel and both ends are fixed by an end cover. The supporting wheel main pin passes through the bearing and supports the supporting wheel on the bracket. The supporting wheel relative to the bearing can rotate and swing around the axis of the supporting wheel main pin, wherein the bearing is composed of a bearing outer ring, a bearing inner ring and several The roller consists of a spherical surface for the contact surface between the outer side of each roller and the outer ring of the bearing, and a flat surface for the contact surface between the inner side of each roller and the inner ring of the bearing. Because the contact surface between the roller and the outer ring of the bearing in the invention is a spherical surface, the supporting wheel can realize self-adjusting when rotating around the main pin of the supporting wheel. The use of this roller assembly can greatly reduce the wear between moving components, prolong the service life of components, reduce the cost, reduce the noise of cylinder rotation, and improve the economic efficiency.

汽车搅拌车自动离心托轮总成
本专利技术涉及工程机械
,具体涉及一种汽车搅拌车自动离心托轮总成。
技术介绍
搅拌车托轮总成是搅拌车中的重要组成部件。托轮总成主要用于支撑搅拌罐体转动,由于搅拌罐体的重量较大,所以对托轮总成的质量要求较高。托轮的回转轴线与搅拌车滚筒轴线的平行度是稳定运行的关键。若上述两轴线不能保持平行,则会引起运动副之间的串动,从而直接影响运动构件的使用寿命。而现有的托轮是无法调整,因此搅拌车的筒体在滚动时就会与托轮造成共振,噪音大,而且设备容易损坏。
技术实现思路
为了克服现有技术中存在的上述不足之处,本专利技术的目的在于提供一种结构简单,安装方便,动作平稳的汽车搅拌车自动离心托轮总成。本专利技术通过下述技术方案实现:汽车搅拌车自动离心托轮总成,包括托轮、托轮主肖、轴承、支架,所述轴承安装在托轮内且通过侧盖固定,所述托轮主肖穿过轴承将托轮支撑在支架上,所述托轮相对轴承可绕托轮主肖轴线转动和摆动,其中轴承由轴承外圈、轴承内圈和若干个滚子组成,各所述滚子外侧面与轴承外圈接触面为球面,各所述滚子内侧面与轴承内圈接触面为平面。进一步地,本专利技术所述轴承两侧分别设有与支架支撑的端盖,每个端盖套设有油封,其中一油封端部紧贴端盖,另一油封端部紧贴托轮。进一步地,本专利技术所述端盖和托轮上均设有用于限制油封密封的限位块。进一步地,本专利技术所述油封一端设有橡胶套,其另一端设置有金属圈。进一步地,本专利技术所述油封截面呈喇叭形状。进一步地,本专利 ...
