Gear Reducer Technical Notes
The main reason for the loss of the axle is from the above gears. Gear) Macroanalysis and mirror analysis of axle cut-off, as well as the results of the fatigue calibration, can determine the special speed-reducing machine of the decomposition cell
First, the main reasons for the break-up of the second gear axis are the following: Axial cut-off, the central area of the axis and the border microorganism are defective tissues, the crystals are thick, and the heat is processed. temperature It's too high, which increases the flaccidness and resilience of the axis. toughness And it's not very plastic. The planet's gear-retarder is also called the planet's speed-retarder, and it's waiting for the speed-retarder. In the speed-reducing family, the planet's speed-reducing machine, with its small size, speed-reducing efficiency, speed-reducing range and accuracy, has many advantages, and is widely applied to the power-receiving system, such as the electric machine, the step-up machine, the straight-flower. Its function is to be used primarily to reduce the rate of rotation to increase the twister and to reduce the rate of movement of the load/engine. Retarder)
I. I. Inadequate intensity of fatigue and low safety factor for the second gear axis
The main reason for the broken axle is the macro-analysis of the cut-off from the above-mentioned gear axle. Analyse) and mirror analysis, as well as irritation calibration results, can determine the rater of the decomposition cell. Retarder)
I. Secondary gears Gear Axes fractured () fracture The main reasons for this are that at the axle cut-off point, the central area of the axis and the border microorganism are defective tissues, the size of the crystals, and the high temperature of the thermal treatment (ch ⁇ l-l-l-l-l-l-l-l-l-l-l-l-l-l-L-l-l-l-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L-L- toughness) and plastic is inadequate. Decomposition cells are special.
I. The intensity of fatigue in the secondary gear axis (() strength 5. The combined effect of the material ' s organizational defects and fatigue, which result in the early formation and rapid expansion of the crack source to the heart, and the deterioration of the operational accuracy (accuracy) of the operation, and the subsequent break-off of the axes under the payload effect.Hard-noodle gear brakes.The drive equipment, which is usually used for low-speed, large-twirling rectangulars, can also achieve the desired speed-reducing effect of a few of the same principle gears, and the ratio of the teeth to the size of the gears is a moving ratio. As the speed-reducing industry continues to develop, more and more firms are using the speed-reducing machines.
All the decompressors of the decompressor's axle are broken.
I. Second-axis, with a slightly larger number of fractured roots for the second-axis than for the first-axis. Gear There was no load jump (zhá) before the axle broke (Zhá) tripping) For example, there are clear signs of a sudden accident causing a forced stoppage. position Most of the response is concentrated in sensitive (sensitized) areas.
The macro-analysis of the cut-off can be seen as sand-striped, full-cut, less visible, and very few smooth areas, indicating the short time between the break-ups and the break-ups.
Macroforma beach stripes;b final fracture (b) fracture A mirror analysis of the cut-off in the zone shows that the centre of the axis is the same as the border microorganism, all upper bezid + small stripes, with thick crystals and essentially the same microclinics, with a typical upper beige fracture at the cut.Planetary gear decelerator.As the speed-reducing industry continues to develop, a growing number of firms are using the speed-reducing machine. Micro-scans of the broken mouth show that the fractures formed on the surface extend to the heart in a 45-way direction, the cutthroats of the cutthroats, and can be observed along the crystalline line, as well as ice-sugar fractures.
The surface crack spreads to the heart in the direction of 45 angles, and it is clear from this that the presence of this defective tissue of upper Bessor reduces the resilience of the axis; the overall cut-off is the same with the same micro-hardness, indicating that the hard layer of the cylindrical is too deep, the crystals are thick and the temperature of the heat is shown to be heated. temperature (b) High, which increases the flaccidness of the material.
It can be argued that the lack of the necessary resilience and plasticity of the gear axes is due to the faulty gold-phased organization obtained from thermal (ch ⁇ l) treatment. Under load working conditions, surface crack sources in stress concentration areas are formed and extended to the heart, and the formation and extension of cracks result in trace deformation and destruction of the gear axis at the initial stage (e.g. vandalism The pre-existing geometric operating centres have caused a deterioration in the operational accuracy (accuracy) of the gear axes, which in turn has led to an increase in the impact load of the j ⁇ n yún, resulting in a rapid expansion of the source of cracks, causing the fatigue of the gear axes in a short period of time.
3. 2 Fragile Nucleus to further prove gears Gear) Fragmentation of the axis () fracture) It is necessary to have a fatigue calibration of the 1-2 gear axis.

Table 1 and 2 gear axes are measured as basic data.
Validation calibration indicates that the speed-reducing machine (ATM) Retarder) First-stage cog axis safety factor, Interceptor IS = 1 05, cross S = 1 56, second-stage cog line IS = 0 7, cross S = 1 01, all smaller than S = 1 3, 1,5, which is another cause of the axle fracture (fact). Fact The fractures that occurred also coincided with the dangerous cross-section of the concentrated response.
