Application News of DK Heavy-load Hollow Rotary Platform

Heavy-duty hollow rotary platform is an extremely practical rotary platform, it has a hollow spindle and load support structure, has a simple structure, easy to use and maintain, in various fields are widely used in various industrial fields, such as: chemical, petroleum, iron and steel, electric power and other industrial fields, can withstand a large number of radial and axial loads.

The structural characteristics of precision heavy-duty hollow rotary platform are introduced:

The rotating platform is supported by a set of precision crossed roller bearings, the rollers in the bearings are staggered at 90 degrees, and the diameter of the rollers is slightly larger than the size of the raceway between the inner and outer rings of the bearings, so that there is a preload between the inside and outside of the crossed roller bearings and the rollers, and the hollow rotating platform supported by the bearings is able to withstand a variety of moments in the radial direction or bearings, tilting and other moments, and the use of a single-stage helical gear reduction mode to increase the output torque, the gear grade Precision in the following 5 levels, hollow rotary platform of the hollow structure, servo side connection, convenient electrical installation, by changing the gear center distance way to control the side gap, so that the hollow rotary platform is very small empty back, repeat positioning accuracy of 5 arc seconds or less, hollow rotary platform through the customized flange and the input shaft hole way, the flexibility to change the size of the interface becomes larger, suitable for connecting any brand of stepping motors / servo motor, hollow The hollow rotary platform can be accurately positioned at any angle;

High load and high precision: the roller and cam are matched without clearance, which can maintain high dividing precision and high torque, and ensure the ability to bear heavy loads;

Heavy-duty hollow rotary platform internally adopts cam input and rotary shaft output, which can lift any movement, and can realize high load and high precision, with high speed and smoothness of high output drive;

Smooth and noiseless: the output shaft is designed to rotate continuously at any position, so the drive is smooth with very little vibration and noise.

High speed and no vibration: Pre-pressurized loads are applied to the precision-machined taper support rib of the rollers and cams, completely avoiding the generation of backlash and making the turntable run smoothly and at high speeds, and fully controlled acceleration reduces shocks generated by loads or vibrations;

HTM/HTN hollow rotary platform, the use of spiral guide program Hai Bo teeth than spiral bevel gears have the advantages of higher reduction ratio, high precision, high torque, low wear, running in a sliding mode, so that the transmission efficiency of up to 96%, the transmission accuracy can reach 30 arc seconds, gear geometry tolerance ≤ 0.002mm, suitable for lifting, horizontal mounting, side mounting and other working conditions.

In short, the heavy-duty hollow rotary platform is a very important automation equipment, in the choice of rotary platform, should be based on the actual application requirements and working conditions for comprehensive consideration, to select to meet the conditions of the hollow rotary platform, and strictly comply with the corresponding use of procedures and precautions, with the continuous development of science and technology, I believe that the hollow rotary platform in the future prospects for applications will be more broad.
