Iranian Knowledge-Based Firm Indigenizes Epicyclic Gear Train
“We have two machines for gears; one is an epicyclic gearing set and the second is a fixed gear set. Most of these two gears are used in industrial gearboxes, automobiles, agricultural machinery, and engineering designs,” said Ali Akbar Shafadi, the managing director of the knowledge-based company.
“These gearboxes are a platform for power transmission, and the purpose of making a solar gear is to teach where and how power can be increased,” he added.
Noting that the epicyclic gear train, in addition to being smaller and more efficient, transmits a higher capacity, Shafadi said, “The educational purpose of this device is that the students use this gearbox to load the rail and obtain the power, etc. of the course that this device navigates. Also they get to know how the gearbox works.”
In a relevant development in August, an Iranian inventor had also succeeded in designing and producing an automatic overdrive gearbox for heavy vehicles which can change gears in less than a second.
Moslem Assadi, the managing director of Bakhtar Gearbox Makers company, stationed at the incubator center of Islamic Azad University’s Kermanshah branch, presented his technological idea titled ‘automatic overdrive gearbox for heavy vehicles and won the honor medal of INV from the International Federation of Inventors' Associations.
“The device we designed is related to the Zf heavy vehicle gearbox in Germany. These gearboxes are one of the most high-quality gearboxes in the world and can be installed on all types of cars of the Benz Myler, Iveco, Volvo, etc. and they are known as overdrive among the users in the world,” Assadi told ANA.
“The way it works is that in heavy cars, unlike passenger cars, due to the high weight of the car, the car accelerates slowly when shifting gears, and in the zf design gearbox and the front part of the shaft, an additional gear is installed, which is forward and backward by the overdrive system,” he added.
“In addition, the overdrive system reduces excessive pressure on the bearings and prevents the so-called dead gear phenomenon,” Assadi said.
