Code number of slewing bearing
2, transmission type code according to table 2 rules.0 Non gear type; 1 involute cylindrical gear outer teeth smaller modulus; 2 involute cylindrical gear external tooth larger modulus; 3 involute cylindrical gear internal teeth smaller modulus; 4 involute cylindrical gear internal teeth larger modulus.3, basic code rulesThe fundamental code layout, structure type code and transmission type code of practice, between the front middle and back with "separated.".
Bearing code representation of fundamental code is divided into three parts, the front for the construction and transmission type code for rolling body shape, middle diameter (more than two rows of bearing roller for maximum rolling diameter), the rear rolling circle diameter of the bearing weight (more than two rows of rolling bodies for maximum roll weight circle diameter)1. Construction codes shall be in accordance with the rules of table 1.01, four point contact ball bearings; 02 double diameter ball bearings; 11 inserted cylindrical roller bearings; 13, three row cylindrical roller bearings.
The code representation of slewing bearing is made up of Dandong phase three turntable bearing manufacturing Co., Ltd. collects and provides a code name. The bearing code is composed of the basic code and the post code. Two, the fundamental code consisting of fundamental code is divided into three parts, the front for the construction and transmission type code for rolling body shape, middle diameter (more than two rows of bearing roller for maximum rolling diameter), the rear rolling circle diameter of the bearing weight (more than two rows of rolling bodies for maximum roll weight circle diameter), 1 tectonic type code according to table 1 rules. 01, four point contact ball bearings, 02 rows of different diameter ball bearings, 11 insert cylindrical roller bearings, 13, three row cylindrical roller with bearings 2, transmission type code according to table 2 rules. 0 no gear involute gear tooth 1 small modulus involute cylindrical gear tooth 2 large modulus involute gear tooth 3 small modulus involute cylindrical gear teeth in 4, 3 large modulus 3 fundamental rules for the preparation of basic layout code code, code structure and transmission type code to write, between the front middle and back "separated.".
