Plum coupling processed through turning, milling, broaching and other machining methods, and then through the whole heat treatment. In order to ensure sufficient mechanical strength plum coupling of two types, the market there is a claw plate is cast, it is possible mass production, but also eliminates the processing loss. So in terms of price is much lower than machining, but performance is not very good casting. In some important occasions or should not be used. And casting prongs at high speed or high load conditions prone to fight tooth (claw tooth loss).
(1) compact, backlash-free, offers three different hardness elastomer;
(2) can absorb vibration, compensate the radial and angular misalignment;
(3) simple structure, easy maintenance, easy to check;
(4) maintenance-free, resistant to oil and electrical insulation, temperature 20 ℃ -60 ℃;
(5) Plum elastomer has four, six, eight and ten;
(6) Covered wire fixation, clamp, keyway fixed.
ML Series plum-shaped flexible coupling consists of two main closely meshed with teeth and bear radial pressing to transmit torque, when the two axes relative offset elastic element corresponding elastic deformation occurs, played the role of automatic compensation.
Tag example: ML3 type plum-shaped flexible coupling elastic element MT3 hardness ≥75HZ
Active end: Z type shaft hole, A-type keyway, d1 = 30mm, L1 = 60mm
Driven end: Y Type shaft hole, B-type keyway, d2 = 25mm, L = 62mm
