Though one might not think of gears to be versatile, gear couplings are very much regarded as a flexible coupling. A gear coupling je sigurno a mechanical device designed to transmit torque between two shafts that are not collinear. The coupling typically contains two flexible joints, one set to each shaft. These joints tend to be linked by a third shaft called the spindle.
Each joint generally includes a 1:1 gear ratio internal/external gear set. The tooth flanks and outer diameter of the external equipment are crowned to allow for angular displacement between your two gears. Mechanically, the gears are equivalent to rotating splines with modified profiles. They are known as gears because of the relatively huge size of the teeth. Gear couplings are usually limited by angular misalignments of 4 to 5°.
Gear couplings ordinarily come in two variations, flanged sleeve and continuous sleeve. Flanged equipment couplings consist of short sleeves encircled by a perpendicular flange. One sleeve is positioned on each shaft so the two flanges line up face to encounter. A series of screws or bolts in the flanges keep them together. Continuous sleeve equipment couplings feature shaft ends coupled collectively and abutted against each other, which are then enveloped by a sleeve. Generally, these sleeves are constructed with metal, but they can also be made of Nylon.
Single joint gear couplings are used to connect two nominally coaxial shafts. In this application the device is named a gear-type versatile, or versatile coupling. The one joint allows for minimal misalignments such as installation errors and adjustments in shaft alignment because of operating conditions. These types of gear couplings are usually limited by angular misalignments of 1/4 to 1/2°.

Gear couplings are torsionally rigid and are supplied to two designs – completely flexible and flexible/rigid. A completely flexible coupling comprises two hubs with an exterior gear and two outer sleeves with an internal gear. It’s a universal coupling for all sorts of applications and accommodates all feasible misalignments (angular, offset and mixed) and also large axial moments. Machines, bearings, seals, and shafts are therefore not put through the additional forces, sometimes of substantial magnitude, which occur from unavoidable misalignment usually associated with rigid shaft couplings.
A flexible/rigid coupling comprises one flexible geared half and one rigid fifty percent. It does not support parallel displacement of shafts but will accommodate angular misalignment. This kind of couplings are primarily utilized for “floating shaft” applications.
Sizes 010 – 070 all have crowned teeth with a 20° pressure contact. This enables to accommodate up to at least one 1,5° static angular misalignment per equipment mesh. However, minimizing the operational misalignment will increase the life span of the coupling and also the life of other machinery components such as for example bearings etc.

SERIJA H Karakteristike i pogodnosti

Veća sposobnost neusklađenosti
Veličine 1-7 kompenziraju ± 1 1/2 ° statički kutni pomak po mrežici mreže.
Minimizing working misalignment will maximize the life span of the coupling. Refer to the Set up and Alignment Instructions for alignment recommendations.
Veće mogućnosti otvora omogućavaju najekonomičniji odabir veličine za osovine do 10 5/8 ″.
Higher Torque Ratings because of bigger tooth pitch diameters than various other couplings.
Versatility in that Series H’s are interchangeable by half coupling with competitive coupling designs.
1 1/2° Curved-Face Teeth are a prime feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth type with flank, tip, and root curvature. When
used in combination with the straight faced sleeve teeth, these 1 1/2° curved encounter hubs offer increased shaft misalignment capability
All couplings feature precision-drilled flange bolt holes, and tight tolerance Grade 5 flange bolts to assure a long-lasting flange to flange and fastener fit. Exposed bolt flanges are
regular. Shrouded bolt flanges can be provided through size 5. Size #5 1/2 and larger couplings are only available with exposed bolt flanges.

Each sleeve flange comes with two pipe plugs 180° apart. This permits assembly of a full flex coupling with four lube plugs positioned every 90°, facilitating lubrication. The lube seal is definitely a Buna-N O-ring to greatly help retain grease and exclude contaminants. KHP or KSG coupling greases are recommended in order to obtain maximum operating life.
