Installation and removal of pulleys

这里是标题一h1占位文字

Install 1. Check the pulley groove to make sure there are no scratches or sharp edges, and all dimensions are up to standard; 2. Clean the surfaces of all parts, such as hub holes, taper sleeves, bolt holes, etc. Fit the cone sleeve into the pulley, aligning all the screw holes. 3. Apply oil to the screw (TB 1008-TB 3030) and thread (TB 3525-TB 5050) and screw them into the mounting holes, but do not tighten them yet. 4. Clean the surface of the drive shaft, push the pulley with the tapered sleeve installed to the predetermined position on the shaft, and check whether the V-belt pulley is aligned. 5. When using the keyway, it must be inserted into the hub first, and there must be a certain tolerance between the keyway and the hole hub. 6. Using a hexagonal wrench conforming to the DIN911 standard, alternately and gradually and evenly tighten the bolts in each mounting hole until the torque shown in the table below is reached.

6. Using a hexagonal wrench conforming to the DIN911 standard, alternately and gradually and evenly tighten the bolts in each mounting hole until the torque shown in the table below is reached.
7. After a short period of operation (0.5 to 1 hour), check the tightening torque of the bolts and retighten if necessary.
8. In order to prevent the intrusion of foreign matter, fill the connection hole of the hole with grease.
disassemble
1. Loosen all the bolts, take out one or two of the bolts according to the number of disassembly holes, lubricate the bolt pattern and the tip of the bolt with oil, and insert the bolt into the disassembly hole shown in the figure below.
2. Tighten the bolts alternately until the taper sleeve and pulley are loosened.
3. Take out the taper sleeve and pulley from the shaft
