Bucket tooth and bucket tooth assembly
The invention discloses a bucket tooth and a bucket tooth assembly, and relates to the technical field of excavating machinery, and the bucket tooth and the bucket tooth assembly are characterized in that the bucket tooth comprises a tooth tip, two tip blocks are arranged at the operation end of the tooth tip at intervals, coaxial penetrating openings are formed in the two tip blocks, threads are formed in the inner walls of the penetrating openings, and limiting columns are screwed into the penetrating openings in a matched mode through the threads; each limiting column is of a cylindrical structure with one end being a spherical head, and the spherical heads of the two limiting columns get close to each other between the two tip blocks along with screwing-in of the limiting columns. A rolling wheel is rotationally arranged between the two tip blocks, bowl-shaped embedding grooves are formed in the two side faces of the rolling wheel, the spherical heads of the limiting columns are in movable clearance fit with the embedding grooves, and the rolling wheel can move in the axial direction of the rolling wheel. According to the bucket tooth, sliding friction of the tooth top can be reduced, abrasion is reduced, the service life is prolonged, the rolling wheels can be independently replaced and are convenient to maintain, meanwhile, a self-cleaning function is achieved between the rolling wheels and the limiting columns, and the situations of jamming and unsmooth rolling can be avoided.
本发明公开了一种斗齿及斗齿组件，涉及挖掘机械技术领域，其技术方案要点是，包括齿尖，齿尖的作业端间隔设置有两块尖端块，两块尖端块内均开设有同轴心的贯穿口，贯穿口的内壁上开设有螺纹，各贯穿口内均配套螺纹拧入有限位柱，限位柱为一端为球形头的圆柱状结构，随着限位柱的拧入，两根限位柱的球形头在两块尖端块之间相互靠近；两块尖端块之间转动设置有滚轮，滚轮的两侧面均开设有呈碗状的嵌入槽，限位柱的球形头与嵌入槽活动间隙配合，滚轮能够沿着自身轴向进行位移。该斗齿可以减少齿尖滑动摩擦，降低磨损，提高使用寿命，而且滚轮可以单独更换，方便维护，同时滚轮与限位柱之间具有自清洁的功能，可以避免卡壳和滚动不畅的情况。
