aodisi Z5 220*285,Z5 130*180 keyless locking devices

 Z5  Locking Devices/Locking Assemblies/Shrink Disc (JB/T7934-1999) 

Application: mining machinery, coal mining machinery, ball mill, belt conveyor, packaging machinery, heavy machinery, light industrial machinery, food machinery, CNC machine tools, metallurgical machinery, textile machinery, printing machinery, plastic machinery, chemical machinery, paper machinery, Marine machinery, tobacco machinery, fans, blowers, reducers, etc.

Model: Z5 sleeve locking device 

Compared with the Z4 type, the Z5 type expansion sleeve has the same taper of each cone ring, and the inner ring has a flange in the middle for easy disassembly.

The Z5 type has a long joint surface and a small taper, and is used for transmitting large loads and high precision in alignment.

The Z5 expansion sleeve is suitable for the coupling of shaft and shaft parts to transmit torque, axial force or a combined load of both.

The shaft tolerance combined with the expansion sleeve is h8 and the tolerance band of the hole is H8.

Material: 45# steel 

Nominal torque/ rated torque:  14.4KNm-1363KNm 

Hole diameter: 100mm- 600mm 

The Z5 type expansion joint screw has a mechanical performance rating of 12.9.

1, installation:

The expansion sleeve is greased at the factory and can be installed directly. When installing, first screw three bolts 4 into the screw holes of the flange of the other part 1 and spread them evenly around the circumference to open the inner sleeve 1 and the outer sleeve 2. Then place the expansion sleeve into the hub hole of the design position and tighten the bolt with the force gauge. The method of tightening is to screw each bolt to 1/4 of the rated torque at a time. The order of tightening is bounded by the slit. The left and right cross symmetry is tightened one after the other to ensure that the rated torque value is reached. 

2. Disassembly:

Loosen all bolts a few turns before disassembly. Then screw in the bolt 4 top loose sleeve in the disassembled screw hole. 

3. Protection:

MoS2 oil is strictly prohibited during installation to prevent contamination of the expansion sleeve. On machines with poor open air or working environment, rust-proof grease should be applied regularly on the exposed end face and bolts of the expansion sleeve. The expansion sleeve type with better rust resistance should be selected.
