A case study of gear wheel material and heat treatment effect on gearbox strength calculation

Silvia Maláková,Anna Guzanová,Dagmar Draganovská,Gabriel Fedorko,Vieroslav Molnár 대한기계학회 2019 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.33 No.12

The paper is focused on the influence of gearing material and thermal or chemical-thermal processing of wheels on the results of the strength calculation carried out in accordance to the standard, in particular on the safety factor. This effect is examined on a gearbox that was part of the steel coil production line in the integrated steel plant. Due to changes in production, the load on the gears increased. Thus, the result of this work is the selection of new materials for the two-speed gearbox and their heat treatment to meet the safety conditions of the gearing mechanism without changing the geometrical parameters of the gearbox.

<ABSTRACT>When the expression "quality" is used, we usually think in terms of an excellent product or service that fulfills or exceeds our expectations. These expectations are based on the intended use and the selling price. For example, a customer expects a different performance from a plain steel washer than from a chrome-plated steel wasger because they are a different grade. When a product surpasses our expectations we consider that quality. Thus, it is somewhat of an intangible based on perception.According to ANSI/ASQC Standard A3-1987, quality is the totality of features and characteristics of a product or service that bear on its ability to satisfy implied or stated needs. Stated needs are determined by the contract, whereas implied needs are a function of the market and must be identified and defined. These needs involve safety, availability, maintainability, reliability, usability, economics (price), and environment. Price is easily defined by some monetary unit such as dollars. The other needs are defined by translating the features and characteristics for the manufacture of a good product or the delivery of a service into specifications. Conformance of the product or service to these specifications is measurable and provides a quantifiable and operational definition of quality. If the specifications do not satisfy the customer needs (fitness for use). they should be changed. Needs usually change over time. thereby requiring a periodic reevaluation of specifications.Quality control is the use of techniques and activities to achiecve, sustain, and improve the quality of a product or service. It involves intergrating the following related techniques and activities : 1. Specifications of what is needed 2. Design of the product or service to meet the specifications 3. Production or installation to meet the full intent of the specifications 4. Inspection to determine conformance to specifications 5. Review of usage to provide information for the revision of specifications if needed Utilization of these activities provides the customer with the best product or service at the lowest cost. The aim should be continued quality improvement. Statistical quality control(SQC) is a branch of quality control. It is the collection. analysis, and interpretation of data for use in quality control activities. While mush of this book emphasizes the statistical approach to quality control, this is only a part of the total picture. Statistical process control(SPC) and acceptance sampling are the two major parts of SQC. A number of different techinques are needed. All the planned or systematic actions necessary to provide adequate confidence that a product or service will satisfy given requirements for quality is called quality assurance. It involves making sure that quality is what it should be. This includes a continuing evaluation of adequacy and effectiveness with a view to having timely corrective measures and feedback initiated where necessary. There is a distinct difference between quality control and quality assurance. Quality control is involved with the activities of specification, design, production or installation, inspection, and review of usage. These activities are the responsibility of the functional areas. Quality assurance is involved with these activities as well as the entire quality system. The generic elements of a quality system are given later in the quality manatgement.

Dance was once considered an expression of individual feeling, but many studies have shown that dance is more related to cultural pattern. Foreign countries have recently more accessible, and interest in other cultures has therefore increased. Intra-cultural dance styles are also part of search for deeper understanding of dance as a cultural and universal experience, as well as the different elements in apparently foreign culture. The paper was studied Alan Lomax's Choreometrics, a dance-work rating system, as a methodology of understanding certain basic cultural aspects of dance. Its descriptive coding system includes study of the followings: (a) body parts habitually involved, (b) the body attitude, (c) nature of transition.

A systematic study on the reaction of the lithium-borane system in tetrahydrofuran with representative organic compounds under standardized conditions (THF, 0℃, H?/compd=4/1) has been carried out in order to characterize the reducing characteristics and entity of this reducing system. Most aldehydes and ketones are reduced rapidly to the alcohol stage. Carboxylic acids and acid chlorides are rapidly reduced to corresponding alcohol stages are reduced only slowly. Nitro compounds are very slowly reduced and sulfur compounds are essentially inert to this reducing system. Consequently, this system possesses both reducing characterictics of borane, an acidic type, and lithium borohydride, a basic type.

통영 내만 투명도의 변동

1997년 1월부터 1999년 12월까지 통영 내만의 5개 정점에서 관측한 총 624회의 투명도 자료를 정리하여 투명도의 계절 및 경년변동의 특성을 조사한 결과를 요약하면 아래와 같다 1) 3년 간의 투명도 편차 범위는 0.2~8.3m이었다. 투명도의 연평균은 지점에 따라 그 변화의 추이가 서로 상이하게 나타났다. 일부 투명도 분포는 대수정규분포로 나타낼 수 있었다 2) 월평균은 지점에 따라 차이가 켰으나 5~9월에 전반적으로 낮은 경향을 보였다. 3) 계절평균은 전반적으로 겨울에서 여름으로 가면서 낮아지고 가을에 상승하는 경향을 보였으나 지역에 따라 다른 양상을 보였다. 변동계수는 봄에 지역적인 차이가 가장 심하고 여름에 지역 차이가 작았다. 4) 정점간의 상관성은 북만에 위치하는 두 지점 사이에는 높은 상관을 보였으나, 다른 정점간에는 상관성이 약하게 나타났다. 5) 25시 관측에서 투명도의 주간과 야간, 대조와 소조, 창조와 낙조 및 고조와 저조의 차이가 분명하지 않았다. Water transparency, Secchi depth in meter, was observed 624 times totally at five sites in the bays near Tongyeong-si during 1997 through 1999 and analysed statistically. The range was 0.2~8.3m mean 2.3m, and variation coefficient 50% in totally. Some distributions of each sampling site could be fitted to the log-normal distributions. Each sampling site showed a different patterns by each sites in the monthly and seasonal changing.

활성오니로 부터 분리한 PHB 분해세균의 특성

김말남 상명대학교 기초과학연구소 1996 기초과학연구 Vol.9 No.-

PHB를 유일한 탄소원 및 에너지원으로 사용하는 세균 5주를 서울시 소재 중랑천 하수처리장의 활성오니로부터 분리하였다. PHB 생분해도가 가장 높은 균주 1주를 선택하여 그 특성을 조사한 결과 Gram 음성의 구균(1㎛)으로 PHB를 보강한 무기염배지와 비교할 때 복합배지에서 배양하였을 때에 약 100배 이상 더 많이 성장하였고 항생제 ampicillin, cephalothin 및 streptomycin에 내성을 나타내었다. 여러 생화학적 검사를 실시한 결과 이 균주를 Enterobacter cloacae FC-101로 동정하였다. Five bacteria capable of degrading and utilizing PHB as sole carbon and energy source were isolated from the activated sludge of the wastewater treatment plants at Seoul Jungrangchun. One strain, exhibiting the most effective capability for PHB degradation, was characterized to be a gram negative coccus. The strain grown in rich medium was 100 times as numerous as that cultivated in mineral medium supplemented with PHB. It showed resistance to antibiotics such as ampicillin, cephalothin and streptomycin, and was identified as Enter-obacter cloacae FC-101 by the biochemical tests.
