Agricultural machinery bearing selection method
2018-01-09
Bearings are supports for rotating shafts or movable parts of various machines. They are widely used in agricultural machinery such as agricultural vehicles, tractors, diesel engines, electric motors and threshers. Buy bearings commonly used bearing code, but the bearing code is more complicated, if the identification of agricultural machinery hand the code of the law, the purchase is easy.
Commonly used bearings are some of the standard models, code-named "0", tolerance level "G" (general level), the first paragraph of the general bearing can not write, so many of its code-named to the basic code of 7 digits. Now illustrate the meaning of bearing code: Example 7002136 (135 series diesel engine main bearing), the basic code from right to left to identify. "36" double digit means that the light, which is calculated as 36 × 5 = 180 mm; "1" means that the diameter series of extra-light; "2" means the type of cylindrical roller bearings; "00" No wall; "7" means the width series is narrow. If the hands buy 7-digit other standard models bearing code can be similar.
Buy bearing multi-reference bearing diameter, bearing diameter in the basic code with the first right and second digits. Bearing diameter sub-standard and non-standard diameter, the difference between the non-standard diameter is not an integer or integer multiples of 5. To facilitate the purchase of hand, is an example:
1. Bearing diameter of 9 mm below the first digit with the right end of the actual size that. For example, bearing number 18, the inner diameter is 8 mm.
2. Bearing diameter in 10-17 mm with a fixed number. For example, bearing number 100,201,302,403, the inner diameter of the code for the right two digits are 00,01,02,03, the inner diameter of 10,12,15,17 mm fixed figures that.
3. Bearing diameter of 20-480 mm (except 22,28,32), in addition to the inner diameter size of 5 said.
4. Bearing diameter of 500 mm or more (22,28,32) with a fraction that denominator diameter, the size of the molecular bearings that series, type and structure. For example, 30031/560 bearing, the inner diameter of 560 mm, and so on and so forth.
