1. The code of the code number consists of the root code and the post code.
Second, the composition of the fundamental code is divided into three parts; the front part is the layout type and the transmission type code; the middle part is the roll diameter (the maximum roll body diameter for the bearings of two rows or more of the roll body); the rear part is the middle of the roll body Round diameter (bearings for two rows or more of rolling elements are the largest diameter of the intermediate body of the rolling body)
1. The layout type code is according to the rules of Table 1.
01 four point contact ball bearing 02 double row reducer ball bearing 11 inserted cylindrical roller bearing 13 three rows of cylindrical roller combined bearing 2, transmission type code according to the rules of Table 2.
0 toothless 1 involute cylindrical gear outer teeth smaller modulus 2 involute cylindrical gear outer teeth larger modulus 3 involute cylindrical gear internal teeth smaller modulus 4 involute cylindrical gear internal teeth larger The modulus 3 code code is used when the code is coded; the layout code and the drive code are written consecutively; the front, middle and back are separated by “.”.
The injection molding machine has a dense plastic product that can be molded in a single shape, accurate in scale or with metal inserts; it is widely used in national defense, electromechanical, automobile, transportation, building materials, packaging, agriculture, culture, education and health. Various fields of the day. The injection molding process has excellent adaptability to the processing of various plastics; high production capacity; and easy to complete automation. Today in the plastics industry, the injection molding machine occupies an important position in terms of quantity or variety. And then become one of the fastest growing plastic machinery; one of the most productive models.
