The shaft and related parts are used for power transmission. The primary drive shaft system consists of a shaft section connected by bolted flange couplings and supported by bearings that keep the shaft in place. It requires less maintenance than the chain system. They have high torsional strength. They have a high polar moment of inertia value. They are solid and unlikely to fail.
The shaft is designed so that the deflection is within the permissible range. Excessive deflection can, for example, reduce transmission performance and cause noise and vibration. The maximum allowable deflection of the shaft will be determined by critical speed limits, the minimum deflection required to operate the gearbox, and bearing requirements.
Features:
- They are unlikely to get stuck.
- It requires less maintenance than a chain system.
- They have high torsional strength.
- They have a high polar moment of inertia value.
- Since the internal shape of the shaft is hollow, less material is required.
- They have a large turning radius.
