Product details:
The advantages of Z7B expansion sleeve
1. It is easy to make and install the main engine parts by using bulking sleeve. The shaft and hole of the mounting sleeve are not required to make high precision manufacturing tolerances. No heating, cooling, or pressurizing equipment is required for the installation of the expansion sleeve, and the bolt must be tightened in accordance with the required torque. With convenient adjustment, the hub can be easily adjusted to the desired position on the axis. The expansion sleeve can also be used to connect the welded parts.
The service life of the expansion sleeve is long and the strength is high. The expansion sleeve relies on the friction drive, which has no keyway and no relative motion. No wear and tear is produced in the work.
The expansion sleeve will lose the coupling effect when overloading, and can protect the equipment from damage.
The expansion sleeve can withstand multiple loads, and its structure can be made into many styles. According to the installation load, it can also be used in series.
Expansion sleeve is easy to disassemble and has good interchangeability. Because the expansion sleeve can combine the shaft hub of the larger fit clearance, the bolt will be screwed loose when disassembling, so that the connecting piece can be easily disassembled. When the tension is tight, the contact surface is closely combined with the non-rust and easy to disassemble.
