Direction of Radial Force in Internal Gear Meshing?

In internal gear meshing, the direction of radial force and the circumferential force act at the meshing point of the tooth profile on the pitch circle, passing through the centerline of the two gears. The circumferential force at the meshing point of the tooth profile on the pitch circle coincides with the common tangent of the two pitch circles. The radial force passes through the meshing point of the tooth profile, aligns with the centerline of the two pitch circles, points toward the center of the pitch circle, and is perpendicular to the circumferential force. Introduction to External Gear Meshing: External gear meshing involves two gears with external teeth. It mainly consists of a pair of bearings supporting the gears, along with a housing, front cover, and rear cover. The rotors rotate in opposite directions. The drive shaft extends from the front cover and is sealed by a shaft seal. External meshing also ensures good wear resistance, especially at low speeds. Internal sealing, achieved by a clamping force proportional to the discharge pressure, ensures optimal efficiency. Introduction to Internal Gear Meshing: Internal gear meshing involves one gear with external teeth and one with internal teeth (teeth inside a hole). The meshing of these two gears is called internal meshing. Internal gear pumps include involute gear pumps and cycloidal gear pumps (also known as rotor pumps). The advantages of internal gear pumps are compact structure, small size, light weight, long service life, low pressure pulsation, and low noise. The disadvantages are complex tooth profiles, high machining accuracy requirements, and higher costs.

Does the Parking Diesel Heater Consume a Lot of Electricity?

Diesel heaters do not consume much power from the battery. How diesel heaters work: Diesel heaters primarily heat the engine's coolant by burning fuel, achieving the effect of warming up the engine before starting. During winter traffic jams or after parking, you can use the heater for warmth without starting the engine. Precautions for using diesel heaters: Modifying a vehicle to install a diesel heater involves altering the original fuel and electrical systems. It is essential to pay attention to installation standards and ensure safety compliance during installation; otherwise, various issues can easily arise. When using a diesel heater, maintain proper air circulation inside and outside the vehicle to avoid carbon monoxide poisoning due to excessive buildup.

What are the functions of fuel additive?

Fuel additive functions include removing carbon deposits, reducing fuel consumption, and restoring power. Effects of fuel additive: Fuel additive is a common name for fuel system cleaner, which can to some extent clean the fuel injectors and fuel system, improve the atomization effect of the fuel injectors, promote thorough mixing and combustion of air and gasoline, and with the help of antioxidant detergents, remove gum and moisture from the fuel system, thereby achieving the effect of cleaning carbon deposits. Testing of fuel additive: After adding fuel additive to a vehicle, the tested vehicles showed no significant changes in power, and the same was true for instantaneous fuel consumption, with very little cleaning effect observed. If you want to improve engine power or directly reduce fuel consumption by adding fuel additive, do not expect it to deliver such results.

Are Insurance-Designated Repair Shops Reliable?

Whether an insurance-designated repair shop can be trusted depends on the reputation of the insurance company and the technical level of the auto repair shop. Generally speaking, the technology and parts of repair shops designated by insurance companies are relatively reliable, with little difference from 4S shops, so they can be trusted. Definition of Auto Repair: Auto repair is a general term for automobile maintenance and repair. It involves troubleshooting faulty vehicles through technical means to identify the cause of the failure and taking certain measures to eliminate the fault and restore the vehicle to a certain level of performance and safety standards. Categories of Auto Repair: Auto repair includes major repairs and minor repairs. Major auto repair refers to the restorative repair method of repairing or replacing any component (including basic parts) of the vehicle to restore its sound technical condition and fully (or nearly fully) recover its service life. Minor auto repair, on the other hand, refers to the operational repair method of replacing or repairing individual parts to ensure or restore the vehicle's working capability.

How Long Should You Practice for Subject 2 Before Booking the Test?

Subject 2 driving practice can be scheduled for a test after 10 days. Driving schools generally arrange eight half-day sessions for students, with no more than four hours of practice per day. Therefore, the Subject 2 driving practice can be completed in about eight days, and the interval between booking tests for each subject is 10 days. Subject 2 Test Items: Five mandatory test items: reversing into a garage, stopping and starting on a slope, parallel parking, curve driving, and right-angle turning. For large buses, tractors, city buses, medium-sized buses, and large trucks, the test must include no fewer than six items. For small cars, small automatic transmission cars, small automatic transmission cars for disabled people, low-speed trucks, ordinary three-wheeled motorcycles, and ordinary two-wheeled motorcycles, the test must include no fewer than four items. Subject 2 Test Scores: The full score for Subject 2 is 100 points. For large buses, tractors, city buses, medium-sized buses, and large trucks, a score of 90 or above is required to pass. For other vehicle types, a score of 80 or above is required to pass.

How Long Before a Used Car Can Be Transferred Again?

There is no time interval restriction between two transfers of a used car. As long as all documents are complete, the car can be transferred again at any time. After the transfer of a used car, it is usually archived on the spot or within 3 working days. Once archived, the transfer process can be initiated again. It is important to note that before transferring the vehicle, all traffic violations and other issues must be resolved, and there should be no unresolved records such as traffic accidents. Precautions for the transfer of a used car: When relocating the vehicle, it is advisable to consult the local vehicle management office in advance to clarify the name of the office. Relocating to another region requires the compulsory insurance of the vehicle, so do not cancel the vehicle insurance before obtaining the license plate in the new location. Wait until the license plate is obtained before canceling the commercial insurance and compulsory insurance. Before processing the transfer, all traffic violation records of the vehicle must be cleared. Documents required for the transfer of a used car: Original owner's ID card, new owner's ID card, original and duplicate of the vehicle license, purchase tax certificate, proof of payment of vehicle and vessel use tax, motor vehicle registration certificate, criminal inspection report of the vehicle, road maintenance fee receipt, insurance policy/card/invoice. All of the above must be provided in original.
