How to connect the engine and tank gear

If the engine power output shaft is directly connected to the active wheel of the tank, it can theoretically minimize the power in the transmission. The loss, but when the tank armored vehicle is driving, the terrain encountered is very complex, and the driving resistance changes greatly.

Mechanically driven, the speed of the power device is transmitted to the large gear of the turret through a special engine or through a reducer. Then drive the gear ring and bearing to rotate. Through manual control, the physical consumption is relatively high.This generally appeared in early tanks, such as the Soviet T-34. 2.

The transmission device and the engine are connected as a whole through connectors and fixed on a three-point frame, which can be hoisted as a whole. It can be disassembled and installed within 40 minutes on the battlefield, which has gained valuable time for the vehicle to re-enter the battle.

Modern tanks can not only rotate turrets 360 degrees, but also tank guns have a certain pitching ability, and the pitching system relies on the pitch system to achieve tank gun pitching. As we all know, because the tank gun has a strong back seat when fired, it cannot be rigidly connected to the turret.

The installation method of CA6DL235E3F engine timing gear is the installation method of engine timing gear, that is, camshaft gear, camshaft gearThe marked side should face the outside, aim at the pin on the camshaft, press in and put on the lock piece, tighten the mother, and lock the lock piece.

When the engine is working, the flywheel and the pump wheel rotate together, driving the oil in the pump to drive the turbine impeller to rotate. It's like putting two fans together face to face, turning on one fan, and the other fan will also rotate. The guide wheel makes the oil thrown by the turbine hit the pump wheel again, increasing the torque.

Is the engine crankshaft explosion related to the gear chamber?

The impact of unbalanced load: When grinding the crankshaft, when the neck size of the connecting rod becomes smaller, the weight will be reduced compared with the original factory size. The method of grinding the spindle neck adopted in the bending of the crankshaft is to ensure that each spindle neckThe concentricity process will cause the spindle weight to decrease, and the spindle axis will shift to the direction of the crank, resulting in an unbalanced force arm.

The gap between the gear combination is too large or too small. The center distance between the crankshaft main bearing hole and the camshaft bearing hole changes during use or repair, becoming larger or smaller; the center line of the crankshaft and the camshaft is not parallel, resulting in poor gear meshing.

The gap between the gear combination is too large or too small (2) The center distance between the crankshaft main bearing hole and the camshaft bearing hole changes during use or repair, and becomes larger or smaller; the center line of the crankshaft and the camshaft is not parallel, resulting in poor gear meshing.

What is the relationship between the number of teeth of the timing gear of the engine and the crankshaft gear?

1. The following gears are called crankshaft timing gears, and the above two are called camshaft timing gears. The proportion of the number of teeth between the two is 1:2. The number of teeth of camshaft timing gears is twice that of crankshaft timing gears. Because of completing a working cycle of the engine, the camshaft only needs to rotate once, and the crankshaft needs to rotate Move twice.

2. Therefore, the number of teeth of the camshaft timing gear can only be twice the number of teeth of the crankshaft timing gear. If it is a two-stroke engine, the number of teeth of the camshaft timing gear is the same as the number of teeth of the crankshaft timing gear.

3. The transmission ratio is 2:1. The ratio of instantaneous input speed to output speed in the mechanism is called the transmission ratio of the mechanism. The following is a relevant introduction: timing gear: timing gear is a gear that plays a time-scale positioning in mechanical device to complete the relevant control functions.

4. The timing of the car is mainly the timing gear, one in the camshaft position, and the other in the crankshaft position. The ratio of the number of teeth is generally 2 to 1, so if the difference is within one tooth, the ignition will generally occur early or ignition lag, and the engine shakes, affecting the power.

What does the gear of the gearbox look like? How is it connected to the engine?

1. Although the hydraulic torque converter can transmit and increase the engine torque, the torque ratio is not large and the speed change range is not wide, which is far from meeting the needs of the working conditions of the car. In order to further increase the torque, expand its transmission range, and improve the adaptability of the car, an auxiliary transmission is installed behind the hydraulic torque converter, and the planetary gear mechanism is mostly used.

2. It is realized through a hydraulic automatic transmission.The hydraulic torque converter is equipped with three types of impellers. The one connected to the engine is called "pump wheel", the one connected to the output shaft is called "turbo", and the one that plays a regulating role in the center of their inner circumference is called "guide wheel".

3. Nowadays, automatic transmissions are generally hydraulic torque converter automatic transmissions, commonly known as "AT" automatic transmission. It is mainly composed of two major parts: the hydraulic torque converter connected to the engine flywheel. The variable speed mechanism that follows the back of the hydraulic torque converter.
