The aluminum alloy casing protects the spring from being thrown out during operation, and the casing is filled with butter, which not only makes the lubrication good, but also makes the noise when the reeds engage is absorbed by the butter damping.
By tightening the four positioning screws on the end of the coupling, the tent cover is compressed and fixed. It is suitable for the connection and fixation of some stepping motors and servo motors with large torque, such as expansion sleeve diaphragm couplings and expansion sleeve plum blossom couplings. , Expansion sleeve bellows coupling, expansion sleeve GICL type-drum gear coupling, etc.
The initially selected coupling dimensions of the bearing coupling, that is, the shaft hole diameter d and the shaft hole length L, should meet the requirements of the shaft diameters of the driving and driven ends, otherwise the coupling specifications must be adjusted according to the shaft diameter d.
NL type drum gear coupling is a new domestic product and has been widely used. It is suitable for axial and flexible transmission, allows larger axial radial and angular displacement, and has simple structure, convenient maintenance, and easy maintenance. Demolition, low noise, low loss of transmission effect, long service life and other advantages are well received by users.
Drum-shaped gear coupling has the characteristics of high rigidity and flexibility. It is not suitable for equipment that requires vibration reduction and strict cushioning. Let's briefly understand its advantages.
As a common item in factories nowadays, plum blossom couplings have a small number of parts, small radial dimensions, no lubrication, and high load-bearing capacity. A half coupling is required for axial movement. The coupling has a problem with the relative offset of the two shafts. Compensation force.
In many power plants, couplings are used in electrical equipment, and because of long-term use, wear, and frequent replacement, compared with gear couplings, the use of diaphragm couplings not only reduces operating costs , It also reduces noise.
