What exactly is the lift spindle assembly? Let's take a closer look at Ruihai’s technology:
The main shaft assembly of an elevator consists of several key components, including the main shaft itself, the main shaft support, transmission elements mounted on the shaft, and sealing mechanisms. This assembly plays a critical role in ensuring smooth operation and stability during lifting processes.
The main shaft is a hollow stepped shaft designed to allow the passage of steel bars or long rods when needed. It can also be operated using hydraulic or electric clamping devices. The front end of the main shaft features a 60-degree tapered hole, which serves as a reference surface during machining, ensuring precision and consistency in manufacturing.
The main shaft assembly utilizes a two-point support structure, offering advantages such as simplified manufacturing processes and lower costs compared to traditional three-point support systems. This design effectively meets the requirements for rigidity and accuracy, making it ideal for demanding industrial applications.
The front support of the main shaft assembly is equipped with a double-row short cylindrical roller bearing. The clearance of this bearing significantly affects the rotational accuracy of the main shaft, so proper preloading is crucial. If the preload is too tight, it can lead to excessive heat and thermal deformation of the shaft. On the other hand, if it's too loose, it may result in reduced accuracy due to play. Therefore, finding the right balance is essential for optimal performance.
