The dedicated helical gear reducer includes: casing, input cylindrical gear, primary transmission gear, primary transmission cylindrical gear, secondary transmission gear, secondary transmission cylindrical gear, output shaft cylindrical gear, and output shaft. The input cylindrical gear, primary transmission gear, primary transmission cylindrical gear, secondary transmission gear, secondary transmission cylindrical gear, and output shaft cylindrical gear are all helical teeth, The output shaft and input shaft are not on the same horizontal plane. The product uses helical gears instead of spur gears to ensure safety, structurally meeting the installation needs of users, and has the advantages of safety, reliability, and reasonable structure.

The gear reducer has undergone a special design on the installation structure of the reducer: one left installation connecting plate is set as a rigid plate, and the other right installation connecting plate is set as a flexible plate. At the same time, a bearing is added to the input gear shaft as a support point to improve the rigidity of the high-speed input gear shaft, reducing the impact of installation accuracy errors on the service life of the reducer. Due to the above characteristics, the service life of this gear reducer has been extended, making it widely used in many mechanical products such as large-scale lifting machinery in ports.
