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.

HPMC is a water-soluble ether, with thermal gelation properties, which has excellent cold-water soluble and hot water insoluble properties, It is a non-ionic cellulose ether mixture, the solution of non-ionic charges, which can`t react with metal salts or ionic compounds. It has PH stability, strong enzyme resistance and metabolic inertia; also has a good dispersion, emulsification, thickening, adhesion, water retention and protective colloid properties, so they are which is widely used in construction, paint, synthetic resin , ceramics, tobacco, textile, daily chemical, petrochemical and electronics industries.

The main purpose:

1. Construction industry: As a water retention agent for cement sand slurry, the retarder makes the slurry pumpable. Used as a binder in plasters, gypsums, putty powders or other building materials to improve spreadability and extend maneuverability. Used as a paste tile, marble, plastic decoration, paste enhancer, can also reduce the amount of cement. The water retention of HPMC enables the slurry to not crack too quickly after application, and enhances the strength after hardening.

2. Ceramic manufacturing: widely used as a binder in the manufacture of ceramic products.

3. Coatings industry: As a thickener, dispersant and stabilizer in the coatings industry, it has good compatibility in water or organic solvents. Can be used as a paint remover.

4. Ink printing: as a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvent.

5. Plastic: as a mold release agent, softener, lubricant, etc.

6. Polyvinyl chloride: As a dispersant in the production of polyvinyl chloride, it is the main auxiliary agent for the preparation of PVC by suspension polymerization.

7. Other: This product is also widely used in leather, paper products, fruit and vegetable preservation and textile industry.
