关于塑料齿轮强度校核标准 VDI 2736已经发布了。现在将各个部分的介绍发上来。
*************************
【1】VDI 2736 Blatt 1:2014-06
Title (english): Thermoplastic gear wheels - Materials, material selection, production methods, production
tolerances, form design
Document type: Technical rule (draft)
Publication date: 2014-06
Abstract: The standard describes specific characteristics of polymeric gear materials as well as manufacture,
testing and design of thermoplastic gear wheels. The most important properties of polymer materials are
presented in an executive summary. In addition to information on the microstructure, typical material and
physical characteristics, additional reference values are given for the thermal limitations of use.
【2】VDI 2736 Blatt 2:2014-06
Title (english): Thermoplastic gear wheels - Cylindrical gears - Calculation of the load-carrying capacity
Document type: Technical rule
Publication date: 2014-06
Abstract: This standard describes the load-carrying capacity calculation for cylindrical gear teeth made of
thermoplastics. Based on temperature calculation, safety values are determined with regard to tooth base break,
tooth flank damage and tooth distortion. For the first time, an additional wear calculation is described. This
allows a sound life span prediction for the described machine elements.
【3】VDI 2736 Blatt 3:2014-05
Title (english): Thermoplastic gear wheels - Crossed helical gears - Mating cylindrical worm with helical gear
- Calculation of the load-carrying capacity
Document type: Technical rule
Publication date: 2014-05
Abstract: The standard describes the calculation of the load-carrying capacity for crossed helical gears or
snail gears with the materials pairing metal/plastic and a shaft angle of 90°. For the calculation of the
load-carrying capacity the standard covers for the special properties of plastics. The calculation of the tooth
root and tooth flank is based on the design calculation. Since in some cases only a few or even no
characteristic values at all are as yet available, this standard will form the basis for determining
permissible values.
【4】VDI 2736 Blatt 4:2014-06
Title (english): Thermoplastic gear wheels - Determination of strength parameters on gears
Document type: Technical rule (draft)
Publication date: 2014-06
Abstract: The standard describes the determination of load-capacity relevant characteristic values,
temperatures and the degree of efficiency for spur wheels and crossed helical gears. It defines a uniform
method for the statistical evaluation of results from different series of experiments.
