In this embodiment, the user only needs to rotate the threaded column 9 with a simple tool to easily fix and disassemble the wheel, without the need for complicated disassembly and assembly steps, which significantly shortens the maintenance time and reduces the downtime maintenance cost. Through the above design, the problem of replacement caused by wheel damage and wear of the drive belt or rope after long-term use is effectively solved, ensuring the continuous and efficient operation of the elevator while reducing the safety hazards caused by loose wheel damage and improving the safety factor of the overall operation.
[0021] The utility model provides a hoist sheave bearing, wherein the guide mechanism comprises a guide groove and a guide block 11, wherein the guide groove is arranged on one side of the fastening groove, the guide block 11 is located in the guide groove, the guide block 11 is slidably connected to the guide groove, and the guide block 11 is driven to move by the fastening column 7, and the guide block 11 moves linearly in the guide groove, thereby making the guide block 11 move stably linearly in the guide groove, thereby making the fastening column 7 move linearly more stably.
[0022] The utility model provides a hoist sheave bearing, wherein two guide mechanisms are provided and are symmetrically arranged, and by providing two symmetrically arranged guide mechanisms, the fastening column 7 can be made to move linearly stably.
[0023] The utility model provides a hoist sheave bearing, wherein a plurality of the support mechanisms are arranged in a circular array, and the bearing body 1, the mounting ring 2 and the sheave can be stably supported by the arrangement of the plurality of support mechanisms in a circular array.
[0024] The utility model provides a hoist sheave bearing, and the number of the supporting mechanisms is six. By providing the six supporting mechanisms, the mounting ring 2 can be better supported, and the supporting effect of the structure can be stably and reliably improved.
[0025] In the utility model, a hoist sheave bearing is provided, wherein the positioning groove and the positioning block 4 are both in a T-shaped structure. The positioning block 4 and the positioning groove are in a T-shaped structure, so that the positioning block 4 can be more stably located in the positioning groove.
[0026] In the utility model of a hoist sheave bearing, the elastic component 6 is an alloy spring. The alloy spring has the characteristic of good spring properties, so it can stably support the fastening column 7.
