Abstrak. Busi merupakan salah satu komponen dalam system pengapian berperan sebagai penghasil api. Busi terdiri dari berbagai varian yang dalam penggunannya membakar campuran udara dan bahan bakar dalam ruang yang kemudian memberikan pengaruh terhadap peningkatan maupun penuruan kinerja dari mesin. Untuk itu penelitian ini bertujuan untuk mengetahui pengaruh penggunaan tipe busi terhadap kinerja sepeda motor empat langkah 135cc. Metode penelitian dilakukan dengan pendekatan eksperimental menggunakan kendaraan Jupiter MX 135 cc, pengujian dilakukan secara statis dengan menggunakan alat bantu dynamometer type prony brake. Data yang diukur berupa putaran di poros engkol dan putaran dari prony brake  pada berbagai variasi beban prony sebesar 3kg, 4kg, 5kg dan 6kg (beban diletakan pada pedal rem cakram belakang) yang kemudian dikonversikan ke dalam satuan Newton untuk dua tipe busi masing – masing yakni busi standar dan busi platinum. Berdasarkan data-data tersebut dihitung torsi pada prony brake, torsi motor, dan daya efektif. Hasil penelitian menunjukan bahwa torsi maksimum dan daya maksimum kendaraan untuk penggunaan busi standar dicapai pada reduction gear 4 sebesar 10,74 Nm dan 5813,11 W dibandingkan dengan reduction gear 1, 2 dan 3. Begitu juga dengan tipe busi Platinum menghasilkan torsi maksimum dan daya maksimum pada reduction gear 4 sebesar 8,24 Nm dan 4684,22 W lebih rendah dibandingkan busi  Standar. Dari hasil pengujian dapat dilihat busi platinum harus digunakan pada kendaraan yang mengutamakan kecepatan tinggi namun hanya menerima sedikit pembebanan (torsi kecil) sedangkan busi lebih di khususkan pada kendaraan harian yang mengutamakan torsi yang besar namun tidak membutuhkan kecepatan tinggi.

The Finite Element Model

To assure the safety of the power bogies for train, it is important to perform the durability analysis of reduction gear considering a variation of velocity and traction motor capability. In this study, two types of applied load histories were constructed from driving histories considering the tractive effort and the train running curves by using dynamic analysis software (MSC.ADAMS). Moreover, this study was performed by evaluating fatigue damage of the reduction gears for rolling stock using durability analysis software (MSC.FATIGUE). The finite element model for evaluating the carburizing effect on the gear surface was used for predicting the fatigue life of the gears. The results showed that the fatigue life of the reduction gear would decrease with an increasing numbers of stops at station.

The Royal Danish Navy frigate Peder Skram successfully passed her sea trials on March 15–19, 1966, and has been in operation for about nine months, with an accumulated gas turbine operation of 490 hr at the end of December 1966. The frigate has twin-screw CODOG propulsion machinery consisting of a 22,000-shp jet-engine-fed power turbine and a 2400-shp two-stroke diesel engine. These two alternative prime movers drive the propeller shafts with controllable-pitch propellers through a common reduction gear including freewheeling clutches. The control system is described, embracing the governor system, the maneuvering system, and the instrumentation and safety systems. Operational experience at sea, including parts of the trials, is described, as well as experience gained by the Royal Danish Navy, including the voyage made by the frigate to the United States in October–December 1966.

This paper firstly starting mechanism of vibration and noise from gear, gear noise mechanism is explained, and analyze the factors and the impact of noise on the gear reducer. Secondly, the establishment of a complete solid model of gear reducer and reducer model for finite element model, the reduction gear box gear reducer of modal analysis and finite element modal calculation, and points out the dynamic analysis of structure, size and weight factor is proportional to the reciprocal of the modal frequencies of each mode is the with the frequency is low, that is, the greater the weight. Once again, the main measure of load and control of gear noise of gear is analyzed, including the calculation, for exciting force reduction gear reducer gear load computation. The analysis and calculation are the theoretical basis of gear structure design and its performance evaluation.

Current domestic and international for the experimental apparatus been associated asynchronous motor design generally used hand horseshoe magnet rotates to drive the rotor rotates, While it is possible to achieve, the apparatus is too simple, and the effect is not in great satisfaction. To further improve the experimental results, a new type of asynchronous motor experimental device is designed, whose working mechanism is a DC motor as a driving source, driven by a reduction gear mechanism to produce a rotating magnetic field, the control circuit can be achieved by utilizing the rotational speed and adjust direction. By apparatus of the stator, rotor apparatus, the related motor control and display device design can make the operation more stable, more easily observed. The experimental apparatus can enhance students' awareness and understanding of asynchronous motor, so that the original abstract theory becomes boring incomprehensible gusto, to stimulate students' desire for knowledge, strengthen students' practical knowledge and ability, with higher practical significance. The apparatus simple shaped, with simple and safe operation, is able to facilitate teaching, with better promote the use of value.

Tribological Characterization

There is a great consumption of grease in an excavator (∼200 Kg/year). This big amount of lubricant is poured directly to the environment. A grease based in sunflower oil and polymer thickener has been developed. An extensive tribological characterization has been carried out in order to ensure a good compromise between EP and AW properties so that the grease could be used in two different applications: in the reduction gear (crown) and in the articulations (bushing/pin). The performance of the biogrease has been compared with two reference mineral lubricants.

Abstract An object-oriented programming (OOP) technique is investigated in order to develop the framework for mechanical design automation systems. A task-oriented decomposition approach is applied to conceptualize the task-object (or task-performing-object) in which common behavior and communication protocols are encapsulated [1]. Each task in the entire design process, either controlling design strategies or performing design methods, is made into an object. The design method objects are implemented using Artificial Intelligence (AI) paradigms, such as artificial neural networks and expert systems. This report explains how OOP is integrated to develop a mechanical design framework (MDF). A single reduction gear box design process was used to identify some of the general tasks involved in mechanical design process. From this process the guidelines for developing task-objects for future systems are formed. Full details of these guidelines and an implementation example in Smalltalk on a PC are available in [7].

Approach Zero

The combined wear of water-lubricated bearings supporting a flexible shaft has a modal characteristic, that is, the cumulative wear can be represented by distinct patterns (modes) that increase geometrically at unique rates. The instantaneous wear rates decrease exponentially with time and approach zero asymptotically. The total load on the outboard bearings decreases and the total load on the inboard bearings increases: the redistribution of outboard and inboard loads is controlled by the shaft stiffness matrix (the reaction influence numbers). The characteristics of modal wear are examined and the changes in alignment loads are calculated, particular attention being paid to reduction-gear loads. Numerical results are displayed.
