Heavy Duty Hollow Rotary Platform is an industrial rotating equipment that integrates high-precision transmission, strong load-bearing capacity, and a central hollow structure. It is designed to achieve precise rotation, indexing, or continuous rotation of workpieces or mechanical structures under high load conditions. Its core feature is to withstand huge loads through high-strength structures, ensure positioning accuracy through precision transmission systems, and solve engineering problems such as pipeline threading and workpiece avoidance through central hollow channels. Heavy Duty Hollow Rotary Platform is widely used in heavy manufacturing, automated production lines, heavy equipment and other fields.
Heavy Duty Hollow Rotary Platform is a rotary motion system designed specifically for high load, high-precision industrial applications. Its core feature is the combination of a large hollow through-hole structure and super strong load-bearing capacity. It meets the demands of demanding scenarios such as heavy-duty machining, automated assembly, and precision testing by integrating high rigidity bearings, high torque drive systems (such as worm gears, gear drives, or direct drive motors), and hollow shaft designs.
When selecting Heavy Duty Hollow Rotary Platform, it is important to pay close attention to the following parameters to ensure that they match the load and operating conditions:
|
Category |
Core Parameter |
Description |
|
Load capacity |
Maximum output torque, radial load, axial load, and overturning moment |
Should be calculated based on the load weight and center of gravity offset. It is recommended to reserve a safety factor of 1.2 to 2 times |
|
Precision indicators |
positioning error, repeated positioning error, backlash, and rotation resolution |
For precision scenes, models with backlash ≤ 1 arc minute and positioning error ≤ 0.05 ° should be selected |
|
Hollow parameters |
hollow aperture, tabletop diameter, and through-hole length |
The aperture should be larger than the diameter of the threading pipeline/workpiece, while also considering structural rigidity (excessive aperture can reduce load-bearing capacity) |
|
Transmission performance |
transmission ratio, input/output speed range, transmission efficiency |
Planetary gear transmission efficiency is usually 85%~95%, and efficiency affects energy consumption and heat generation |
|
Environmental adaptation |
protection level (IP code), working temperature, humidity range. |
IP65 or above protection is required for humid/dusty environments, and special heat dissipation design is required for high temperature scenarios |
|
control interface |
driver type (servo/stepper), control signal (pulse/bus), and encoder feedback |
compatible with the upper control system (such as CNC, PLC) |
