Here are the structural characteristics of drive shafts shared by Drive Shaft Suppliers, please feel free to contact us if you need
The drive shaft is a high speed, less supported rotating body, so its dynamic balance is crucial. Generally the driveshaft is dynamically balanced before it leaves the factory and is adjusted on a balancing machine. For a front engine rear wheel drive car is the shaft that transmits the rotation of the transmission to the main gearbox, it can be several sections, and the sections can be connected to each other by universal joints.
The drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The drive shaft is connected or assembled with various accessories, and the circular object accessories that can be moved or rotated are generally made of light and good torsional resistance alloy steel tubes. For a front-engine, rear-wheel-drive car, it is the shaft that transmits the rotation of the transmission to the main gearbox, which can be several sections connected by universal joints. It is a high-revving, less-supported rotating body, so its dynamic balance is critical. Generally the transmission shaft is dynamically balanced before it leaves the factory and is adjusted on a balancing machine.
The driveshaft is composed of a shaft tube, telescopic sleeve and universal joint. The telescopic sleeve can automatically adjust the distance between the transmission and the drive axle changes. Universal joint is to ensure that the transmission output shaft and the drive axle transmission axis of the two axis line angle change, and to achieve the two axes of equal angular speed transmission. General universal joint cross shaft, cross bearing and flange fork and other components. The drive shaft universal joint used in the Steyr series of heavy vehicles uses a roller cross shaft bearing, with a short and thick cross shaft, can transmit a large distance. Butterfly spring is provided at the end of the bearing to compress the roller. The end face of the cross shaft has a reinforced nylon spacer with spiral grooves to prevent sintering when transmitting power at large angles or large distances.
The conventional structure of the drive shaft expansion sleeve is a spline sleeve welded to the flange fork, and the spline shaft is welded to the drive shaft tube. GWB's drive shaft is a change from the traditional structure, the spline sleeve and the drive shaft tube are welded together, and the spline shaft and the flange fork are made into one. And the rectangular tooth spline is changed into a large pressure angle involute short tooth spline, which not only increases the strength but also facilitates the extrusion molding to meet the needs of large torque working conditions. In the expansion sleeve and spline shaft teeth surface, the overall coating of a layer of nylon material, not only to increase the wear resistance and self-lubricating, and reduce the impact load on the drive shaft damage, to improve the cushioning capacity.
This type of drive shaft outside the flange spline shaft added a tube seal protection sleeve, in the protective sleeve end set two polyurethane rubber oil seal, so that the expansion sleeve inside the plant to form a completely sealed space, so that the expansion spline shaft from the erosion of external sand and dust, not only dustproof and rust-proof. Therefore, when assembling the spline shaft and sleeve, a one-time application of grease can fully meet the requirements of use, no need to install oil nozzle lubrication, reducing the content of maintenance.
Drive shaft is a high speed, less supported rotating body, the prisoner of its dynamic balance is essential. General drive shaft in the factory before the dynamic balance test, and in the balance machine for adjustment. Therefore, a set of drive shaft is a matching factory, in use should pay special attention.
