Stand-by decelerator (LRT) Retarder It's usually used with organic racks like JXLD gears. Gear How can we make the structure of the stand-down brakes more rational? 
 Stand-by decelerator (LRT) Retarder It's usually used with organic shelves, such as JXLD support, A-carriers, M-speeders, etc. How can it make the structure of a standing speed-reducing aircraft more rational?
First of all, analyze it. Analyse Unreasonableness in the design of the stand-by wheel-frame structure 1) The speed-reducing machine is calculated (tng guo) Retarder)
　　One, two-axis, all of which are large, and cylindrical ball-rolling bearings. bearing (b) 3. Low energy consumption, high performance, and more than 95 per cent energy efficiency; 5. The selection of high-quality exercise steel materials, steel cast iron containers, high-frequency thermal processing of gear surfaces, and the precision process to ensure axle parallelity and positioning bearing requirements, the formation of an agglomerated speed-reducing machine equipped with a variety of types of electric power, combined with a combination of electron integration, fully assures the quality of product use.
2) Sphere-roll bearings (Spheral roll bearings) bearing Axes () bearing) cannot be adjusted if assembly (assemble) fixed (in accordance with drawing requirements) fixed............................................................. bearing After that, the axis's axle is equal to the bearing. bearing) the axle trajectories, which are approximately four to seven times the trajectories of the ball-roll bearings, and which are quite large, as can be seen from the SKF Manual, at the normal level of 23938CC/ W33 2404 (Death page) 0C The direction of the C/W33 bearings is original. Original Spacing is 0. 13～0. 2mm 23222CC/W33 bearings with an original gap of 0.00 075～0 12, although the radial gap has been slightly reduced after installation, the axle gap, or axle, is still very high, while the pulsation gears are still very large. Gear It's the most taboo to spread it. taboo) Large axle-jumping.Hard-noodle gear brakes.The most efficient of all forms of transmission is that of transmission, which is more efficient than that of snails. The efficiency of gear-reducing machines is largely determined by friction of gears and bearings.
3) Spirillage gears () Gear) At the time of installation, it was positioned by matching the back cone with a reloading of the gearing gear with a moving load () load) Under impact () influence) Most important element of carrying capacity () factor) is the shape and position of the gear contact () position) There is a tendency for the two umbrella gears to be separated, as both axes point in the direction of the working axle towards the greater end (trend With a large axial force, the propeller gear moves in an axial direction, and the area of the rotor's contact is directed to the root and the top. Directional movement and a long direction of the tooth caused by a vertical curvature will result in the area of exposure moving to the end of the gear, which is most afraid of end contact, especially large-end exposure, as long-term exposure at the end causes early failure of the gear, or even loss of teeth 。gear reducer motorThe use of gears at all levels to achieve speed-reduction purposes. Speed-reducing devices are made up of gears at all levels. For example, the use of small gears to drive large gears can achieve a certain speed-reducing purpose, and the use of multi-stage structures can significantly reduce the rate of turn-off.
4) Because of 2
　　V and 4V are often inverted and have to reverse steel, and in reverse, both axes point in the direction of both axes to the lower end of the larvae, where the passive axis is already at the lower end due to gravity. position) So the active axis screw moves internally, the area of active cavity contact moves to the top and the large end, and the traverse is lower (reduce Because of the bearing () bearing It's too big an axle, so it's even possible. maybe It'll be zero, that's it. Condition) It's very dangerous. It can cause a broken tooth.. In the light of the above, it is recommended that the propeller-pattern gears (Gear) For the support read two single-column cones () Tapered) The roller bearings are placed back-to-back, so that they can both withstand a large axis and adjust the course, the axis gap, and the back-to-back axis expands to thermal. inflate This is a set-off.
