Description

technical field [0001] The invention relates to the electric power manufacturing equipment industry, in particular to a horizontal winding machine. Background technique [0002] Winding machine is an important production equipment in the power manufacturing equipment industry. It is an important process equipment for completing the production elements of transformers, transformers, inductors and many other power products. With the leap of the technological level of power equipment, the voltage level of transformers , The capacity is constantly increasing, and the weight of the coil winding is also increasing, so the requirements for the performance and structure of the winding machine are more prominent, but its development is relatively lagging behind, the coil diameter is large, the linear speed is large, the centrifugal force is large, the wire tension force, The pressing force, integral main shaft, rotating torque of the winding die, load, etc. all increase accordingly. ...

AI Technical Summary

Problems solved by technology

[0003] 1. During the gear transmission process of the main shaft speed change mechanism, the speed change is multi-stage speed change, there are many gears, and the gear load is too large during output, which is easy to cause slippage and gear loss, and multi-gear transmission is easy to generate noise;

[0004] 2. The main shaft adopts rolling bearings, and the dynamic and static loads are relatively weak, which cannot meet the requirements of large tonnage and large diameter coil weight and stress, leaving hidden dangers for the main shaft transmission process;

[0005] 3. The faceplate of the main shaft is large, and the force is transmitted to the winding die through the fork, and the shear force at the left end of the main shaft bearing and both ends of the winding die increases, causing impact;

However, under the basic condition of static load, the top bearing force at both ends must also bear the weight of the coil and the torque force transmitted to the winding die by the disc shift fork. The linear speed will generate centrifugal force and tension force during the wire winding process. Compression force, etc., so almost all the stress is concentrated on the tops at both ends. According to the on-site investigation and analysis: the tops are easy to wear, easy to slip, and even easy to break. Small, causing top fatigue hazards;

[0007] 5. The structure of the tailstock is unreasonable, the size is too small, the active top is limited by the Morse taper, the bearing capacity of the internal ball bearing is limited, the top and the Morse taper shank journal are small, the bearing capacity is not enough, and the force on the top is concentrated. The protection of the support roller frame still cannot improve the structural defects
