Foreword

This revised standard adopts ISO 5292.1995 "belt and ribbed V belt drive power rating calculation." In order to maintain existing national standard This standard is GB/T 11355-1989 "V belt drive power rating calculation" amendment. The main technical differences between standard compared with GB/T 11355-1989 as follows. --- Ribbed belt increased rated power calculations. This standard is proposed and managed by China Machinery Industry Federation. This standard was drafted. Productivity Promotion Center in the machine. The main drafters of this standard. Huang Gang, Qin Shuan. This standard replaces the standards previously issued as follows. --- GB/T 11355-1989. Vp and ribbed belt power rating calculation

1 Scope

This standard specifies the computing industry with two V-belt pulleys and ribbed belt power rating and a correction term and the correction coefficient formula. This standard applies to the current cross-section V-belt and V-ribbed belt national standards also apply to the process of being developed and V-ribbed belt With a cross-section.

2 Terms and definitions

Under conditions of transmission properly installed and maintained, according to the geometry and environmental conditions specified in the prescribed period of time, given Single V-belts and ribbed each wedge can transfer power. Rated power is a cross-sectional V-belt and V-ribbed belt, pulley small pulley pitch diameter and small angular velocity function. About gear ratios, corners and tape Long-term correction, have been included in the calculation formula.

3 formula

Each V-ribbed belt of each belt or wedge rated power P delivered by the following formula. P = K (P1 + ΔP1 + ΔP2) Where. K = m1 m1 -1 (L m1 - π) 10 + 1 C2 Ju - () 1 among them. M1 --- V belt when 5, when the V-ribbed belt is 4 or 5; α --- small pulley wrap angle in radians (rad); P1 --- basic rated power, in kilowatts (kW); ΔP1 --- the gear ratio value caused additional power, in kilowatts (kW); ΔP2 --- caused by the additional power with a long value, in kilowatts (kW); ω --- small pulley angular velocity in radians per second (rad/s); C1, C2, C3, C4 --- parameters satisfy a certain level and (the same or different manufacturers of different types of quality specified period of time with the quality Level with the parameters may be different);
