Steel Casting Connecting shaft
A connecting shaft is a cylindrical component used to connect different parts of construction machinery and transmit power. It typically uses bearings, keys, and other components to achieve stable power transmission and mechanical structure.
Core Function
It primarily supports rotating components (such as wheels and hydraulic pumps) and transmits rotational force or torque, ensuring the coordinated operation of all components in the powertrain.
Structural Features
Material: Common materials include steel and nylon, with some using special alloys for improved wear resistance.
Connection Method: Connects rotating components (such as gears and sprockets) to the shaft via a key, ensuring that concentricity within a reasonable range is maintained.
Application Scenarios: For example, connecting the engine and hydraulic pump, or the drive wheel and transmission system in an excavator.
Frequently Asked Questions
Strict concentricity must be maintained during installation. Failure to do so may result in abnormal bearing wear, coupling damage, or increased vibration of the entire machine.
