Z14 Keyless Shaft Locking Assemblies Device

Locking Device Z14 Assembly Locking Shaft

Products Features

Features of expanding and tightening coupling sleeve: the connecting centering machine can work well; No heating is required during assembly; It is convenient to adjust the corresponding position of the shaft and hub; No stress concentration; Strong bearing capacity; High torque; Good stability; Precision measurement; Do not damage the mating surface. For example: belt pulley, sprocket, gear, bevel pulley, impeller, synchronous belt pulley, propeller, large and small fan, blower or direct connection with shaft and hub and other transmission connections. After disassembly, all bolts can be loosened without removing the bolts. Then screw the appropriate bolts into the disassembly hole with an Allen wrench and loosen the disassembled parts

1. Use the expansion sleeve to make the manufacturing and installation of host parts simple. The machining of the shaft and hole for installing the expansion sleeve does not require high-precision manufacturing tolerance as interference fit. When installing the expansion sleeve, there is no need for heating, cooling or pressurizing equipment. Only tighten the bolts according to the required torque. The adjustment is convenient, and the hub can be conveniently adjusted to the required position on the shaft. The expansion sleeve can also be used to connect parts with poor weldability.

2. The expansion sleeve has long service life and high strength. The expansion sleeve is driven by friction, and there is no keyway weakening or relative movement to the connected parts, so it will not be worn in work.

3. When the expansion sleeve is overloaded, it will lose the connection function and protect the equipment from damage.

4. The expansion sleeve connection can bear multiple loads, and its structure can be made into a variety of styles. According to the installation load, multiple expansion sleeves can also be used in series.

5. The expansion sleeve is easy to disassemble and has good interchangeability. Because the expansion sleeve can combine the shaft hub with large fit clearance, loosen the bolts during disassembly, so that the connected parts can be easily disassembled. When expanding and tightening, the contact surface fits tightly, does not rust, and is easy to disassemble
