Product Description
BL type pin coupling is a coupling suitable for connecting two coaxial transmission shaft systems, with compensation for relative offset of two shafts and general shock absorption performance. Its working environment temperature range is -20℃ to +70℃, and it is not suitable for parts with high requirements for shock absorption effect and noise control.
Main features:
1. A pin made of several non-metallic elastic materials is placed in the flange holes of the two half couplings to achieve connection.
2. Simple structure, easy to manufacture and assemble.
3. Convenient installation and replacement of elastic elements without moving the two half couplings
Use:
BL type pin coupling is mainly used to connect two coaxial transmission shaft systems, with compensation for relative offset of two shafts and general shock absorption performance
Application scenarios:
BL type pin coupling is widely used in various heavy machinery and equipment, such as metallurgy, mining, ships, lifting and transportation.
In particular, in transmission systems that need to withstand large torque, radial load and have certain displacement compensation requirements, BL type pin coupling performs well.
Product advantages:
1. Strong bearing capacity: Due to the design of the rod pin, the BL rod pin coupling can withstand large torque and radial load, and is suitable for heavy-duty transmission occasions.
2. Strong compensation ability: The rod pin coupling can compensate for the radial displacement, angular displacement and axial displacement between the two shafts to a certain extent, improving the flexibility and reliability of the transmission.
3. Easy maintenance: The rod pin coupling has a simple structure, is easy to disassemble and repair, and reduces maintenance costs.
4. High transmission efficiency: Due to the large contact area between the rod pin and the groove, the friction loss during the transmission process is small, so the transmission efficiency is high.
Application areas:
1. Mechanical equipment: In various mechanical equipment, such as conveying equipment, mixers, etc., it is used to connect the transmission shaft system.
2. Industrial production line: In the automated production line, it is used to connect various workstations to ensure the stable operation of the production line.
3. Heavy machinery: In heavy machinery, such as cranes, excavators, etc., it is used to connect the power transmission part and withstand large torque and displacement.
