Advantages and Disadvantages of Internal Circulation Ball Screws
Internal circulation ball screws, such as the Hojama 40mm Rolled Ball Screw, have distinct characteristics that make them suitable for specific applications: ?
1. Advantages
?
Compact design: The overall dimensions are compact, with a securely fixed reverser that offers high rigidity and wear resistance. The short ball return channel and fewer balls ensure smooth movement, minimal friction loss, and high transmission efficiency.
Space-saving: For the same nominal diameter, the nut’s outer diameter is smaller than that of external circulation ball screws, making it ideal for applications with limited installation space.
?
2. Disadvantages
?
Shaft processing constraints: The screw shaft must have one end smaller than the root diameter, which imposes stricter requirements on manufacturing and installation precision.
Limitations in harsh conditions: Inferior impact resistance compared to external circulation types, so they are less suitable for large-sized or high-load applications. Additionally, most internal circulation models use plastic reversers, restricting their operating temperature range.
Applications in Industrial Automation
Hojama rolled Ball Screw sets are integral to various automated systems, leveraging their precision and reliability: ?
Robotics: As a core component in robot joint transmissions, they deliver high-precision, high-rigidity, and high-speed motion control, enabling accurate robotic movements.
CNC Machines: Used in lateral, longitudinal, and lifting motions, their high precision, load capacity, and long service life ensure stable machining accuracy.
Semiconductor Equipment: Provide extreme positioning accuracy and repeatability, maintaining stability during high-speed operation to enhance production efficiency.
Medical Equipment: Critical in imaging devices, surgical robots, and bedside robots, ensuring precise positioning and safe operations.
Food Packaging: Control conveyors, fixtures, and robotic arms, ensuring efficient, hygienic production line operations.
