Since the definition of bypass ratio is the ratio of gas flow in the inner and outer bypass channels, how does a gear driven turbofan that slows down the fan increase the bypass ratio??Is it because the torque increases after the fan slows down, resulting in an increase in the inclination angle of the fan blades? Can more air be sucked in?

Helical gear transmission has the following advantages:1. Having a larger transmission ratio: Helical gear transmission can provide a larger transmission ratio, making the structure of the transmission system simple and the structural size small.2. Has good balance: Helical gears have good balance and can reduce noise and vibration.3. Has lower no...

A worm gear reducer is a reduction transmission device consisting of a worm gear and a worm gear. A worm gear is a helical gear, while a worm gear is a cylindrical body with helical teeth. Worm gear transmission is used for two shafts intersecting at 90 degrees. In worm gear transmission, the active part is the worm gear and the passive part is the...

The material selection of general mechanical transmission systems is a broad concept. Here, I will mainly talk about the situation of gear transmission in iron-based friction pairs, which is the selection of gear materials.Gears can be made of various materials, including steel, copper, cast iron, aluminum, plastic, and so on. Among them, steel i...

1. Gear operation generates heata. Overload or ultra high speed.The driving load is too large, causing an increase in gear meshing sliding heat generation.b. Insufficient or incorrect selection of lubricating oil/grease.Too little lubricating oil/grease can cause oil film failure and increase meshing friction. In addition, improper use of lubricant...

1. Transition curve interferenceTransition curve interference refers to the interference at the transition curve between the tooth tip of a gear and the tooth root of the matched gear during the meshing process.2. In order to prevent interference in the transition curve during the meshing process, the selected meshing parameters must ensure...

What is the difference between synchronous belt drive and chain drive? In the eyes of many people, this doesn't seem to make much difference, which is a mistaken view. As long as you observe carefully, you can still see the difference. Synchronous belt drive has more advantages than chain drive. The synchronous belt pulley has the characteristics o...

1. Gas sourceThe air source for the pneumatic system is pure compressed air. So, the commonly used air source components include air compressors, filters, dryers, pressure reducing valves, pressure gauges, oil mist eliminators, and other components. Air compressors mainly produce compressed air (working medium); Filters are mainly used to filter im...

The main characteristics of gear transmission are:1) High efficiency is the highest among commonly used mechanical transmissions, with gear transmission being the most efficient. The efficiency of a first level cylindrical gear transmission can reach 99%. This is very important for high-power transmission because even if the efficiency is only incr...

This article proposes a new concept of using energy driven molecular gears. Using visible light as the energy source, HTI actively promotes different gear transmission processes at the nanoscale.Unlike hot gear transmission, light gear transmission is the dominant movement within the molecular framework. Meanwhile, the conversion of 180 ° doubl...
