- Q:What's the camshaft phase shifter for?
- Photoelectric type crankshaft and camshaft position sensor(1) structural featuresPhotoelectric type crankshaft and camshaft position sensor Nissan production is by the distributor and improvement, mainly by the signal disc (signal rotor), signal generator, distributor, sensor shell and harness plug etc..The signal panel is the signal rotor of the sensor and is mounted on the sensor shaft, as shown in figure 2-22. Two inner and outer light transmitting holes with evenly spaced radian are made near the edge of the signal disc. Wherein, the outer ring is made of 360 light transmitting holes (gaps), with an interval radian of 1. (pervious pores account for 0.5. Shading hole accounts for 0.5. ), is used to generate the crank angle and speed signal; the inner production has 6 light holes (rectangular alone L 60), interval radian. An upper TDC signal for each cylinder, in which a rectangular broadside is slightly longer and is used to produce the TDC signal of cylinder 1.The signal generator is fixed on the sensor housing, which is composed of a Ne signal (speed and corner signal) generator, G signal (TDC) generator and signal processing circuit. The Ne signal and the G signal generator are composed of a light emitting diode (LED) and a photosensitive transistor (or photodiode), with two LED facing two photosensitive transistors respectively.
- Q:Why is the tolerance grade of the shaft higher than the tolerance level of the hole?
- This is because the hole processing, than the same size of the shaft processing is difficult, processing costs are higher, in order to make the hole matching
- Q:How to use CAD to draw axonometric drawing
- Command line input: DS enterPoint capture and raster capture type: equal axis capture.Back to the drawing area, press "F8" to open the orthogonal modeEnter in the command line: L (line command, start drawing)You'll see that the direction is limited,
- Q:That's the line of the painting. It's just moving the coordinate axis. I want to make a rotation of the custom axis. Which prawns help me?!
- When the movement is finished, press the insert button again to get back to normal
- Q:The transmission change ratio is defined as the input shaft speed / output shaft speed. So, is the 1 gear drive larger than the 5 gear transmission ratio?
- When the clutch is cut, the body inertia will drive the car to continue, although it is slowing down, because of its larger quality, tire speed decline is relatively slow. If one end of the crankshaft does not continue to supply oil, the drive will decline faster because of its small inertia.A good shift operation is to keep the crankshaft at one end of the wheel speed, as close as possible to the gear box at the end of the gear shift.Understand that the two points, you can, as required, through the clutch pedal to loosen the speed and depth of the throttle to achieve a better gear shift, improve comfort, but also reduce the wear and tear of the clutch.The simplest and most efficient shift operation is fast shift, fast clutch / fast shift / uniform loose clutch, with the aim of minimizing the speed difference between the flywheel disc and one axle, so that the gear shift is smooth.
- Q:What are the differences between axial and oblique strikes of hydraulic generators?
- . The higher the head drop, the greater the power required to meet the requirements of the pipe. This form can be divided into new and old and new turgo "double double turgo", "four ring pipe spray turgo", according to the change of water source, adjust the number of switching nozzle, make better use of water resources.
- Q:What are the differences between axial fans and centrifugal fans?
- The curved plate blade is welded to the conical steel hub. Change the flow by changing the angle of the blade in the upper inlet housing of the impeller.The casing can have an open entrance, but more commonly, it has a right angled bend to allow the motor to be placed outside the pipe. The excretory shell expands slowly to slow down the flow of air or gas and converts kinetic energy into useful static pressure.The role of axial fans and centrifugal fans in mechanical ventilation1, because the temperature and grain temperature difference is great, the first ventilation time should be chosen during the day, in order to reduce the gap between grain temperature and temperature, and reduce the occurrence of condensation. After the ventilation as far as possible in the evening, because the ventilation is to cool at night, humidity is relatively high, low temperature, so that reduce the water loss, and make full use of the night temperature, improve the cooling effect.2 centrifugal fan for ventilation early there may be a door and window and wall condensation, even slight condensation of surface grain surface, as long as the wind stop machine, open the window, open the axial fan, if necessary, changes the grain surface, the positions within the hot air outside the warehouse can be excluded. When the axial fan is used for the slow ventilation, there will be no condensation. Only the upper and middle grain temperature will rise slowly, and the grain temperature will decrease steadily as the ventilation continues.
- Q:When the textbook calculates the diameter of the shaft, he tells me some of his forces, such as the circumference force of the gear on the shaft, etc.. But in reality, the known conditions are quite small: "now I have a question, how to transform, please help me?"Just know that A is a cylindrical, M, radius R, B as a shaft, and A together, C motor, and B through the chain connection, will now enable A to R RPM speed rotation, so how to determine the motor power, what is the minimum diameter of the B axis? What is the moment and torque that the B axis receives if it is specific? Other conditions to be determined, free to add
- Standard shafts shall be used as far as possible in accordance with the requirements of the shaft. Installation of standard parts (such as rolling bearings, couplings, seals, etc.) of the shaft diameter should be taken as the corresponding standard value and the selected combinations of tolerances.In order to make the gears, bearings and other mating parts to be easy to assemble and disassemble, and to reduce the scuffing of the mating surface, smaller diameters should be used before mating the shafts. In order to make with the axis of the interference fit parts, easy assembly, match shaft pressing end should taper; or the size tolerance in two different parts of the same section of the shaft.
- Q:Two axle. What's the meaning of the three axle and four axle truck?
- Two axle truck refers to: two tires, two or four tires at the end of the car. Commonly known as single bridge trucks
- Q:With regard to the matching system, when to choose the base hole system, when to choose the basic shaft system, what are the basis for selection?
- At this time, the base shaft system (for example, the outer diameter of the rolling bearings is matched with the holes is the shaft system fit).
