Rail transit crankshaft balancing machine

Rail transit crankshaft balancing machine

As we all know, the crankshaft, one of the important parts of the locomotive engine, bears the force from the connecting rod and converts the force into torque, which is output by the crankshaft and drives other accessories above the engine to work. When the crankshaft is subjected to the centrifugal force of the rotating mass, the combined action of the reciprocating inertia force and the gas inertia force when the cycle changes, it is required to have sufficient rigidity and strength, and the surface of the journal needs to be wear-resistant, and the uniformity and balance of the work should be better.

In order to enable the crankshaft of the locomotive to have a better balance performance, to allow the driver and passengers to have a better driving experience, reduce the instability of the locomotive as much as possible, through a variety of unbalanced factor analysis and combined with these problems, Shanghai Jianping developed a special crankshaft balancing machine, this crankshaft balancing machine is more applicable to the crankshaft with weight over 5T.

Product characteristics

Ship-shaped brackets, specially designed for CRRC large crankshaft, transfer mechanical force, durable, small vibration damping, good rigidity.

High sensitivity sensor, good linearity, high machine efficiency.

Once calibration, permanently use, allowing large initial unbalance.

Balancing machine uses universal coupling transmission, smooth power transmission, fast start, easy to operate.

Suitable for rotors whose outer circle can not use a belt transmission device or require a large transmission power.

Jianping independent research and development of electronic measurement system, friendly HMI, easy to operate.

Shanghai Jianping R & D team members from Jilin University, Shanghai Jiao Tong University and other universities and have strong software development ability and mechanical structure design ability. They have solved the precision speed sensor design, precise positioning, mathematical model establishment, automatic tool setting and tool feeding, dynamic density compensation and other problems. We have a full set of system intellectual property rights and can measure, modify, optimize and improve the corresponding solutions to the balancing machine at any time.
