摘要：【中文】本发明适用于提升机技术领域，提供了一种板链斗式提升机尾轮的配重调节装置，包括轴体组件和配重轮组，所述轴体组件包括下轴以及套设于所述下轴外壁的下链轮和轴承座，且所述轴承座位于所述下轴的两端，所述配重轮组包括配重壳体、配重盘、盖体和螺杆；首先打开盖体，对配重壳体内部配重盘的进行添加或减少，进而便可对整个的配重壳体内部的重量进行调节，当调节完毕之后，将盖体盖合在配重壳体之上，并通过螺杆将盖体和配重盘固定在配重壳体上，避免配重盘在使用的过程中出现晃动的情况，便可完成了对配重盘的组装，同时完成了对配重轮组的重量改变，实现了配重轮组的调节，避免了原有不同固定重量的配重轮组之间的固定搭配使用体。 【EN】The invention is suitable for the technical field of elevators, and provides a counterweight adjusting device for a tail pulley of a plate-chain bucket elevator, which comprises a shaft body assembly and a counterweight wheel set, wherein the shaft body assembly comprises a lower shaft, a lower chain wheel and bearing seats, the lower chain wheel and the bearing seats are sleeved on the outer wall of the lower shaft, the bearing seats are positioned at two ends of the lower shaft, and the counterweight wheel set comprises a counterweight shell, a counterweight disc, a cover body and a screw rod; at first open the lid, add or reduce the inside counterweight disk of counterweight housing, and then alright adjust the inside weight of whole counterweight housing, after the regulation finishes, close the lid on counterweight housing, and fix lid and counterweight disk on counterweight housing through the screw rod, avoid the condition that the counterweight disk rocked in the in-process that uses to appear, alright accomplished the equipment to the counterweight disk, accomplished the weight change to the counterweight wheelset simultaneously, the regulation of counterweight wheelset has been realized, fixed collocation use body between the counterweight wheelset of original different fixed weight has been avoided.

摘要：【中文】本发明适用于轴承座技术领域，提供了一种轴承座的密封结构，包括密封盖、密封环、调整套、密封圈、轴承、轴承座、端盖和球体，使用时，在球体的作用下，将密封盖与密封环之间的滑动摩擦更变为滚动摩擦，从而使密封环转动更加顺畅，滑槽底部开设的置物槽，可以对注入到滑槽内部的密封油进行存储，当密封环在转动的过程中，带动球体同步运动，球体外露的部分便会转入置物槽的内部，与置物槽内部的密封油接触，通过置物槽内部所存储的油对球体进行润滑，并跟随密封环的转动将经过润滑的部分转出，最终与密封环上开设的滑槽内壁相接触，不仅大大减小密封环与密封盖之间的摩擦力，而且进一步提高了对轴承的防尘效果。 【EN】The invention is suitable for the technical field of bearing seats, and provides a sealing structure of a bearing seat, which comprises a sealing cover, a sealing ring, an adjusting sleeve, a sealing ring, a bearing seat, an end cover and a ball body, wherein when the sealing structure is used, the sliding friction between the sealing cover and the sealing ring is changed into rolling friction under the action of the ball body, so that the sealing ring rotates more smoothly, a storage groove arranged at the bottom of a sliding groove can store sealing oil injected into the sliding groove, the sealing ring drives the ball body to move synchronously in the rotating process, the exposed part of the ball body can be rotated into the storage groove and is contacted with the sealing oil in the storage groove, the ball body is lubricated by the oil stored in the storage groove, the lubricated part is rotated out along with the rotation of the sealing ring and is finally contacted with the inner wall of the sliding groove arranged on the sealing ring, so that the friction force between the sealing ring and the, and the dustproof effect on the bearing is further improved.
