There are several kinds of roller chain coupling transmission purposes, such as short pitch roller chain coupling, double pitch roller chain coupling, short pitch sleeve chain coupling, bent plate roller chain, toothed chain, forming chain, etc. The roller chain coupling transmission can reduce friction and is used in places where the power is relatively large and the running speed is relatively slow;The roller chain coupling is operated by the chain and the half coupling gear, and its fit requires strict tolerance error.
Roller chain couplings
The pitch of the roller chain coupling is twice that of the standard chain, and its side plate is often a rectangle with a semicircle at both ends, and its shape is very different from the ordinary roller chain, and the shape of the standard sprocket is not much different from the ordinary chain sprocket, the double pitch sprocket is used with the single pitch chain, and the tooth pitch of the sprocket is greater than the due tooth pitch;Single-pitch sprockets are used in conjunction with double-pitch chains, and the tooth pitch of the sprocket should be smaller than the expected tooth pitch.
The sprocket has to determine the size of the sprocket according to the pitch, width, diameter of the roller and the speed ratio of the transmission, and the gear has to determine the situation of the gear according to the torque to be transmitted, the speed ratio and the size of the space. Fix the outer leg of the motor on one side of the coupling of lifting accessories, and move the inner leg until the eccentricity line between the motor and the pump is zero. In order to prevent the motor from moving arbitrarily, after fixing the feet on one side of the motor, the other side should be pressed against the top wire.
Roller chain couplings
Fix the inner leg of the coupling and move the outer leg so that the eccentricity of the two lines is zero. The two half-couplings should be tested against each other, and this method is suitable for rotating equipment with high-speed, rigid connection requirements. Roller chain couplings have cushioning and vibration damping properties that can reduce the size of the coupling, which is also useful for reducing the weight of the coupling, saving materials and reducing costs. Roller chain couplings have the characteristics of smooth transmission and are widely used in low-noise equipment.
