Q:For planetary gears, the fixed ring gear connects the sun wheel and the planet carrier, but does it still move?

(3) the output shaft is usually connected with the forward planetary gear and the rear ring gear assembly (Fig. 7-4). Thus, the mechanism becomes one of these 4 independent components, and is (1) the front ring gear (2), the rear sun wheel assembly (3), and the rear star bracket

Q:What is the cause of the serious wear of the flywheel ring gear of the engine?

The processing quality does not meet the requirements of the drawings, the balance of bad performance, the end of the flywheel axial or circumferential radial runout is too large, so that the two plane cannot smooth joint friction is not uniform, so that the flywheel wavy.When the flywheel rotates, because the clutch is in the separation and the combination instantaneous and the flywheel plane has the rotational speed difference, causes these two relative sliding, causes the flywheel work surface to produce the attrition. The plane of the flywheel will be partially ablated and hardened due to the high temperature generated by the high velocity friction.

Q:Why does the radial runout of the gear ring reveal only the geometric eccentricity of the gear?

The accuracy of the spindle rotation of the workpiece is low.3, the tool scene is larger, or the center of rotation of the tool axis and geometric center error is larger.

Q:1115 how many teeth are used when the diesel engine is switched on?

Disassemble and inspect the suction and hold coils of the motor starter and their contacts

Q:What is the function of the toothed ring clamp in the die?

So that the material in the shear zone is in the three direction compressive stress state; the material is pressed to avoid the bending and tensile deformation of the sheet metal; after the blanking is finished, the material is discharged again

Q:The number of planet gear is 20, the drive ratio is 7.5. The number of teeth of solar wheel and ring gear is required

You drive ratio is really strange, I figure out the sun gear number of 6 points Oh.

Q:Planetary gear reduction problem. The outer gear ring is fixed with 80 teeth, the planet tooth is 30 teeth, the center tooth is 20 teeth.1, can the meshing drive.2, the planet carrier input power, the sun tooth output power. What is the speed ratio?

The ring is fixed, the frame is active, the sun wheel is driven, and the speed ratio of the same direction increase is 1/5 (the number of the teeth of the rack = the number of the sun gear teeth and the number of teeth inside the gear ring;

Q:Can the planetary gear reducer require no gear ring? The solar wheel is active and the planet carrier outputs

Transmission diagram (4) 5 shift operation component is arranged in the Simpson planet gear mechanism (2 clutches and 2 brakes and 1 one-way overdrive clutch), to be a planetary gearbox with 3 forward and 1 reverse gear, the 5 gear shift operation module the layout as shown in Figure 7-5, C1 is used to connect the clutch input shaft and the clutch wheel assembly before and after the sun, C2 is used to connect the input shaft and the ring gear, brake for B1 solid was fixed after the planet carrier, B before and after the sun wheel brake assembly, brake speed clutch F11 B2 and Dan Xiangchao and B2 can use the band brake or disc brake. Simpson type 3 gear planetary gear box gear lever position and operation assembly worksheet

Q:How to remove the flywheel ring gear of the van engine?

Assemble new gear ring: clean the flywheel ring and blow dry first. The ring gear with waste oil is heated to 30035090, so that the inner diameter swell, while hot pressing to rapid vertical flywheel or with a hydraulic machine on the outer edge, and check whether the assembly in place, fit, natural, after cooling has a certain degree of tension. In order to prevent the gear ring from loosening, it can be drilled at every 1200 places and fixed by the steel pin method.After the gear ring is assembled firmly, the chamfering of the gear still needs to be repaired.

Q:The radial runout of the gear ring affects the accuracy of the gear drive, so the gear is to be checked on the shaft and the runout of the end face.

The gear detects the radial runout of the gear ring; it is the pulsation of the teeth of the teeth or teeth; the radial circle of the smooth cylinder is the beating of the cylindrical surface
