A device that changes the speed ratio and the direction of motion. It is used in automobiles, tractors, ships, machine tools and various machines to change the torque, rotational speed and movement direction transmitted from the driving shaft to the driven shaft according to different working conditions. A geared gearbox is generally composed of a case and several gear pairs.Located between...
The drive shaft is the shaft that can transmit power in the drive shaft of the universal gear. It is a high-speed, less-supported rotating body, so its dynamic balance is critical. Generally, the drive shaft must be tested for dynamic balance before leaving the factory, and adjusted on the balancing machine. For front-engine rear-wheel drive vehicles, it is the shaft that transmits the rotation of...
The possible reasons for the abnormal noise of the drive shaft are unbalanced drive shaft assembly, damage to the universal joint, damage to the drive shaft and sliding fork. The assembly error of the drive shaft exceeds the limit, the size of the parts is inaccurate, and the wear and deformation during use are exceeded. The mass of the drive shaft will be unevenly distributed along the length dir...
The reasons for the transmission oil leakage failure are as follows: 1. The oil seal is worn, deformed or damaged; 2. Cracked or damaged gearbox housing or cracked extension housing 3. The air vent is blocked and the oil drain plug is loose; 4. The installation between the cover and the casing of the gearbox is loose or the gasket is damaged; 5. Too much gear oil or improper use of gear oil, resul...
Oil seal is the customary name for general seals, which is simply the seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also generally refers to the general liquid substance).It isolates the parts that need to be lubricated in the transmission parts from the output parts, so that the lubricating oil wi...
Transmission gearbox is a device that changes the speed or traction of machines such as machine tools, automobiles, and tractors. It is composed of many gears with different diameters. It is usually installed between the driving shaft and the driven shaft of the engine. The speed changer is a gear transmission device that can change the transmission ratio of the output shaft and the input shaft fi...
The automobile differential is the main part of the automobile drive axle. The function of the differential is to allow the two half shafts to rotate at different speeds while transmitting power to the two half shafts, so that the wheels on both sides can drive at unequal distances in the form of rolling, which can reduce the friction between the tires and the ground . The reason why a car generat...
1. The crankshaft pulley is a part of the disc hub. The crankshaft pulley is mainly installed at the front end of the automobile crankshaft assembly to drive the overall rotation of the crankshaft. It plays a very important role in the operation of the car. Generally speaking, the size will be relatively large, and the manufacturing process is generally based on casting and forging. Generally, the...
