The invention relates to a novel winching machine roller. The novel winching machine roller comprises a roller body and a roller main shaft located at the axis of the roller body and used for supporting the roller body. A groove is formed in the roller main shaft and meshed with a protruding block in the roller body, the two axial ends of the roller body are fixedly connected with the roller main shaft through a roller hub, six threaded through holes are symmetrically formed in the roller hub in a machining mode according to the center, and six threaded blind holes are symmetrically formed in the outer edge of the roller body according to the center. By adopting the groove and the protruding block which are meshed with each other, the connection between the roller body and the roller main shaft is realized, the defect that an existing roller is rigidly connected with the roller shaft through a key groove of a center hole is avoided, the damage to the roller main shaft is avoided, and the service life of the roller is greatly prolonged.
本发明涉及一种新型绞磨机滚筒,包括:滚筒、位于滚筒轴心处且用于支撑滚筒的滚筒主轴,滚筒主轴上设有凹槽,凹槽与滚筒内部的凸块相啮合,滚筒的轴向两端通过滚毂与滚筒主轴固定连接,滚毂上按照中心对称加工六个螺纹通孔,滚筒外沿按照中心对称加工设计六个螺纹盲孔。本发明通过采用相啮合的凹槽和凸块,实现滚筒和滚筒主轴的连接,避免了现有的滚筒通过中心孔的键槽与滚筒轴刚性连接的弊端,避免对滚筒主轴的损坏,大大提升滚筒的使用寿命。
