How Many Teeth Does a Gear Have?

Gears generally have a module (m) of ≥2. Below is relevant information about gears: 1. Composition: Typically consists of teeth, tooth spaces, end faces, normal planes, tip circles, root circles, base circles, and pitch circles. Each protruding part used for meshing is usually arranged radially, and the teeth of paired gears contact each other to enable continuous meshing operation; tooth spaces are the gaps between two adjacent teeth on a gear; end faces refer to planes perpendicular to the gear or worm axis on cylindrical gears or cylindrical worms; normal planes are planes perpendicular to the tooth line; tip circles are the circles where the tooth tips lie; root circles are the circles where the tooth spaces' bottoms lie. 2. Repair Methods: Gear repair methods include the reversal method, tooth insertion method, gear ring replacement method, plastic deformation method, and welding repair method. Gears often transmit power in one direction, leading to one-sided wear. When their structure is completely symmetrical, they can be flipped 180 degrees and reinstalled for use. If not symmetrical, the gear can first be annealed, the asymmetrical part cut off and welded to the other side of the gear, and then the gear can be heat-treated again.

Is it necessary to wait a full year for license upgrade after B2 downgrade?

After downgrading a B2 driver's license, it generally takes about one year to apply for reinstating the B2 driving qualification. 1. License downgrade system: The downgrade system only applies to large buses, tractors, city buses, medium buses, and heavy trucks, with step-by-step downgrades (minimum C1 class). 2. Cancellation of permitted vehicle classes: No downgrade applies to small cars or motorcycles. Note that if eligible for downgrade, only the highest-level permitted vehicle class will be canceled each time. For example, for a license with both B1 and B2 codes, only B1 will be canceled initially. 3. 12-point record: Applicants must wait one year without another 12-point violation record before applying for license upgrade.

What is the normal coolant temperature for a BMW?

BMW's normal coolant temperature is 90 degrees. The car's radiator consists of an upper water chamber, a lower water chamber, cooling tubes, and cooling fins on the outside of the tubes. The hot coolant cools down by dissipating heat to the air, while the cold air warms up by absorbing the heat from the coolant, making the radiator a heat exchanger. Taking the BMW X1 as an example, its dimensions are 4565mm in length, 1821mm in width, and 1620mm in height, with a wheelbase of 2780mm. The BMW X1 is equipped with a 1.5T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum power of 103 kW and a maximum torque of 220 Nm. It uses a MacPherson strut front suspension and a multi-link rear suspension.

How to Sleep Cool in the Car During Summer?

To sleep comfortably in the car during summer, always open the sunroof if available, prepare a small car fan and a cooling mat. Ideally, power an air-conditioning fan or cooler using the car's negative battery or a 1000W portable power bank. Parking location significantly impacts comfort—choose a well-ventilated spot, install mosquito nets, and lower the windows halfway. Below are key precautions for summer car sleeping: 1. Tip 1: Always activate the car’s external air circulation mode and park in a breezy area with windows slightly cracked to prevent lethal buildup of carbon monoxide (CO) and carbon dioxide (CO₂). 2. Tip 2: When idling, limited air exchange occurs between the interior and exterior. CO, being denser, accumulates around the vehicle from exhaust emissions. Prolonged engine operation may concentrate CO inside the cabin. Combined with occupants’ oxygen consumption and CO₂ exhalation, oxygen levels drop while CO/CO₂ rise, risking unconsciousness or fatal poisoning. 3. Tip 3: Using internal recirculation to maintain temperature/air quality restricts airflow, posing hazards. Never remain in a stationary car for extended periods—whether running AC, heat, or idling—as it’s extremely dangerous.
