Application range and structure of the machine 1. Application scope and advantages: This machine is widely used in various lifting, transportation, mining machinery and other various machinery for deceleration. The linkage mode can be directly linked by the coupling, and the flexible belt can also be used for linkage. The machine has strong versatility and interchangeability, simple maintenance, and an efficiency coefficient of 0.94. It has the advantages of small starting resistance and flexible movement. The structure of the machine is a two-stage three-axis cylindrical helical gear horizontally split and fully sealed. The lubricating oil is contained inside the reducer, and the oil retaining plate is arranged on the driving shaft and the intermediate shaft. The rolling bearing is used for each pivot point, and the axial clearance can be adjusted by the internal adjusting ring. The upper part of the machine has an inspection cover, and the lower part has an inspection cover. Oil pointer and oil for waste oil.
