Aiming at the problem that the applicable scope and results of the three existing domestic standards for the gluing of involute cylindrical gears are not clear, the flash temperature method and the integral temperature method are studied in detail. Through a large number of examples, the similarities and differences and limitations between the standards are compared. The main conclusions are as follows:
(1) In most cases, based on HB/Z 84 The calculated results of the tooth surface temperature of FZG A involute cylindrical gear are better than those of GB/Z 6413 2. 30%~50% higher, mainly due to HB/Z 84 4 The influence of roughness coefficient XR and lubricant coefficient XL is not considered, resulting in average friction coefficient μ M The calculation result is 40%~60% higher, resulting in HB/Z 84 4 is conservative.
(2) In a large range of torque, oil temperature and rotational speed, the calculation results of tooth surface temperature of GB/Z 6413 using flash temperature method and integral temperature method are basically the same, but with the decrease of modulus, GB/Z 6413 1 and GB/Z 6413 2. The error of tooth surface temperature calculation results increases. When the modulus decreases to 2 mm, the error of both is up to 18 6%, GB/Z 6413 2 is conservative, the modulus is within 4~7 mm, and the calculated results of the tooth surface temperature of the two are similar.
(3) Based on GB/Z 6413 2 Calculation standard: for FZG A involute cylindrical gear, the tooth surface temperature of load level 12 is 249% higher than that of load level 3 9%； Compared with the speed of 1000 r/min, the tooth surface temperature increases by 95% 9%； The oil temperature of 120 ℃ is 41. 5% higher than that of 40 ℃ 8%。
