What are the advantages of QLQLZ ball couplings compared to other couplings?

QLQLZ ball couplings have higher bearing capacity than drum-shaped gear couplings and heavy cross universal couplings, stable operation, good cushioning, strong aligning ability, high transmission efficiency, long service life, simple structure, easy maintenance, etc. Features. Dry oil has a long lubrication cycle, convenient maintenance and inspection, no broken teeth and shaft, and accidents. The advantages are obvious. Can work stably under harsh working conditions. Therefore, it is widely used in metallurgy, beneficiation, electric power, heavy-duty transmission and transportation vehicles, ship mooring, port transportation machinery, crane (day) vehicles and other industries, as long as it is a plant and equipment mine using a toothed coupling and a heavy cross universal coupling. The QLQLZ Ball Coupling can be used. The outer surface of the external gear hub of the drum gear tooth coupling and the internal surface of the internal gear flange are circumferentially machined into correspondingly equally divided semi-cylindrical concave arc grooves with drum-shaped balls placed inside and outside. In the cylindrical hole formed by the arc slot, the three cooperate to realize the transmission torque, and a ball retainer is arranged at the port of the arc tooth slot of the outer tooth sleeve to ensure that the balls work on the same circumferential line to achieve synchronous self-alignment within two The flange flange flange is provided with a positioning ring at the flange flange to control the axial flow range of the internal tooth flange flange and avoid the phenomenon of crashing the cover plate.
Compared with the traditional coupling, the spherical roller coupling has very obvious characteristics, mainly in the following aspects:
1, the transmission of large torque, long service life; spherical roller coupling tooth surface is circular arc tooth surface, with high contact strength and bending strength;
2, smooth and efficient, low noise; between the coupling, the ball and the ball between the pair of small friction, the contact gap is small, so high efficiency, low noise;
3, strong ability to align: The relative position accuracy of the coupling to the two shafts is to be low ball, which can replace the tooth coupling to achieve an ideal centering range.
4, easy to maintain. After the use period reaches 2-3 months, remove the end cap and inject the viscous grease. The maintenance cost is low and the operation is simple.

Self-Recovery Rapid Door

High Speed self-Recovery Rapid doors are the technological evolution of old, PVC high speed doors or heavy folding doors, now obsolete and not suited to today's industrial needs.

High-quality panels, the resistive safety edge fitted to the bottom edge of the door, photocells and barriers make this product both safe and durable, being totally self-repairing, thanks to its special [Anti Crash System".

This door designed with a perimeter structure in galvanized or stainless steel, which is ideal for sliding panels. The door panel rides effortlessly within a track, thanks to the special profile and hinge designed by us, requiring low maintenance. The panel is rolled up on a roller placed within the upper crossbeam.

The door can be equipped with a counterweight or ups batteries, to fully open the door in case of power failure, and can also be equipped with large transparent sections to create a brighter and safer working environment.

Self-Repairing Door Curtain made of reinforced PVC, with flexible weighted soft bottom edge.

The edge of curtain has continuous injection molded teeth that then move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames.
