In today's industrial areas of transmission systems, coupling function and role is not the same, but the most consumable couplings such as: heavy, metallurgy, mining, machinery, lifting transportation, petroleum, chemical industry, light industry, automobile, motorcycle, ships, water pump, fan, compressor shaft transmission of mechanical products such as the coupling, and its main function is to transfer power.

Science and technology and the development of industry, promoted the high-power, high speed and high precision and low speed and heavy machinery products and the development of equipment, the transmission system coupling also puts forward new requirements, in addition to transfer torque and exercise outside, still requires a compensation two axes relative offset, improve the transmission efficiency, improve the transmission precision, energy saving, improve the transmission system performance, light weight, carrying capacity, high reliability, comprehensive requirements, in this case, a gear coupling is the ideal solution.

A gear coupling characteristics:

Compact structure, light weight, carrying capacity, compared with other coupling, the torque weight than the largest, transmission torque can be in 250-000N. M range 630 design;

Has for installation error compensation function, but also achieve radial, axial and Angle deviation combination of compensation.

Speed with other coupling wide range, compared to its speed weight than the largest;

High transmission efficiency;

High driving accuracy;

High reliability;

Use maintenance cost is low;

GF a gear coupling characteristics:

The same specifications parts are interchangeable, optimize production and use;

But according to different functions need to undertake integration, combination, the best meet customer demand;

Sauder couplings products completely by oneself to completely ensure production of the product delivery time, the highest and the lowest price; integrity

GF series coupling outer profile can be positive and negative assembly to get three different axial distance, convenient customer use;

Tooth crest undertake repairing margins and help to improve the meshing performance, eliminate gear load, and also reduce tip clearance and radial clearance, improve the transmission stability;

GF coupling using different material and heat treatment process, create different performance products in order to enlarge choices, let the customer get the best cost-effective products;

Sauder couplerhas a special surface treatment or coating protection, improve its corrosion resistance;

In order to guarantee the most simple to assemble and disassemble, fasteners galvanized function, in order to prevent corrosion and unable to tear open outfit;

12.9 grade high strength fasteners provide additional protection couplings failure.

Coupling choices:

A, torque calculation:

Calculation torque (Tc) = theory torque x K = 9550 x power generator power (kW) x K voting speed (RPM)

K - load coefficient, press table selection; (insert condition coefficient table)

B, selection: choose rated torque greater than or equal to work torque specifications

C, view the aperture, wheelbase, allowable speed and rotary space;

Hole - check the biggest size couplings allow. If the aperture is not enough, consider to choose a large scale of the coupling.

Speed - check coupling allow RPM, if insufficient, consider balance; Balance can allow increased by 50% speed;

Wheelbase -- check the gap, couplings shaft length, installation presidents (when in general enough outside every lap with couplings adjust);
