The cast iron worm helical gearbox has a high technological content. It combines helical gears with worm gears for transmission, improving the torque and efficiency of this machine. It is mainly composed of an input shaft, an output shaft, helical gears, oil seals, bearings, worm gears and a housing, etc. The cast iron worm helical gearbox mainly utilizes the meshing between helical gears and worm gears to reduce speed and increase torque. When the input shaft rotates, the high-speed rotation of the input shaft is converted into the low-speed rotation of the helical gear through the meshing of the helical gear. Then, the worm gear meshes with the helical gear, converting the low-speed rotation of the helical gear into the high-torque rotation of the output shaft. The input shaft is connected to the motor, and the output shaft is connected to the driven mechanism. It has a wide speed range, good versatility, and can adapt to various installation methods. The performance is safe, reliable and has a long service life, meeting international standards.

The key components of the cast iron worm helical gearbox motor are made of highly wear-resistant materials and have undergone special heat treatment. It features high processing accuracy, smooth transmission, small volume, large load capacity and long service life. This reducer can be equipped with various types of motors, forming mechatronics. It fully guarantees the quality characteristics of product usage.
