Q:There is no gear with teeth inside or outside, or it is called a ring. The inner teeth are used for internal meshing, and the outer teeth are used for external meshing. Thanks for your help

2, in the transmission of special circumstances, may also have a special gear, both internal and external gear for example, planetary gear drive, a ring gear (also called the internal gear), in the transmission process, if the needs of the entire planetary system to do a whole week to swing, then, can be in a tooth a special ring gear has internal and external gear.

Q:A few days ago to a car POLO, accidentally remove the engine after the ring gear crankshaft behind the crank position sensor to get down, now the engine installed wouldn't burn, a question that is not the ring gear according to the previous position of the good, the master has repaired this a car I ha, very urgent!!!!!!!! Tell me in detail where it is there, the most important is the installation of the ring gear, the engine is 1.4 double cam shaft, 16 valve.

Locate the mark on the gear ring and mark the point on the flywheel.

Q:What is the radial runout error of the ring gear?

The radial runout error of gear ring is a standard for gear post test. Generally speaking, it represents the difference of the teeth on the circumference of a gear. Popular point of view, with the detection of the beating of the outer circle almost, but the benchmark is on the teeth.

Q:How many teeth should the flywheel ring gear of the single speed diesel engine 158D12 teeth of the deceleration starter?

The flywheel has greater rotary inertia. The engine speed varies as the work done by each cylinder of the engine is discontinuous. When the engine speed increases, the kinetic energy of the flywheel energy storage to increase; when the engine speed is reduced, the kinetic energy of the flywheel is reduced, energy is released. The flywheel can be used to reduce speed fluctuations during engine operation.3, installed at the rear end of the engine crankshaft, with rotational inertia, it is the role of the engine energy stored, overcome the other parts of the resistance, so that the crankshaft rotation; through the clutch is installed on the flywheel, connect the engine and drive; joint and starter, so the engine starting. And it is the integration of crankshaft position sensor and speed sensor.

Q:Is the flywheel ring prone to failure?

Reasons for operationWhen the engine is working, sometimes the driver mistakenly switches the ignition switch to the starting gear or causes a malfunction on the 4 moving circuit. If the ignition switch, relay and circuit in vehicle bumped when short circuit caused by a one-way clutch driving gear and the gear meshing force and strong ring scrape. Inspection found that when the situation occurs, most of the ring gear is worn evenly along the circumference, tooth tip 45 degrees chamfer, damage again start, two teeth bite difficult to make the phenomenon of milling more and more serious. This situation is not caused by starter fault, belongs to manual fault or circuit fault, resulting in milling. The method is to strengthen the training and study of drivers' operation, and to enhance their professional skills so that they can master certain theoretical knowledge and be alert to the use and operation of vehicle equipment. In particular, the restart operation of the starter must be strictly spaced at the time of starting. The correct method of use is that the total time of each vehicle is not more than 5 seconds, and the interval is not less than 15 seconds. Also note that the use of starter uninterrupted when starting car will cause the battery due to excessive discharge and damage to the vehicle battery charging condition in time to check whether the lack of electrolyte without added electrolyte must be timely according to the provisions. We do this through the transformation of installing a protection device to prevent repetition priming to protect the engine flywheel ring gear flywheel ring gear and extend the service life of the starter.

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

Check the wear of the starter gear. Check the wear of the flywheel ring gear of the engine

Q:In differential planetary gears, the sun wheel and gear ring are used as the driving wheels. The input speed is ns and NR respectively, and the input power is Ps and Pr respectively. How about the force of the planet carrier as the output?

The torque of each shaft can be calculated by the formula above, the transmission ratio can also be calculated: MN2=MN1 * I *. ETA: efficiency of 1 axis and 2 axis;

Q:The clearance between the slewing ring gear and the drive pinion

And gear accuracy, installation center spacing is related to ~! See the manual ~!

Q:What is the main reason for the radial runout tolerance of gear ring?

The main reason for the radial runout tolerance of gear ring is that:1, the material uniformity is poor.2, the machine tool workpiece spindle rotation accuracy is low.

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.
