Shaft connection in confined space

Mod­ern mechan­i­cal engi­neer­ing is aimed at reduc­ing out­er mass­es with con­stant or increas­ing pow­er den­si­ty. With the bel­lows cou­pling series “KG”, Jakob Antrieb­stech­nik ful­fills the devel­op­ment accord­ing to reduced dimen­sions and high pow­er density.

The KG series, option­al­ly also avail­able in stain­less steel as series “KG-VA”, meets high require­ments. The trans­mis­sion is made via tor­sion­al­ly rigid, two- or four-shaft stain­less steel bel­lows, the cou­plings are avail­able for torque ranges of 5 — 1300 Nm as well as shaft diam­e­ters of 6 — 90 mm. It can be used at tem­per­a­ture ranges from ‑40 ° C to + 350 ° C.

One side is designed as a cus­tomer-spe­cif­ic flange or hub for the machine-side con­nec­tion, the radi­al clamp­ing hub of the oth­er side facil­i­tates easy and fast assem­bly and guar­an­tees an absolute­ly play-free, secure and force-trans­mit­ting trans­mis­sion of the torques, even with­out a keyway.

The con­nec­tion between bel­lows and hub is made by a micro-plas­ma weld­ing process. This offers con­struc­tive advan­tages, such as the reduced over­all length. The cou­pling is absolute­ly back­lash free, high con­cen­tric and has max­i­mum tor­sion­al stiffness.

The cou­plings are par­tic­u­lar­ly suit­able for use on the input side of low-back­lash worm or plan­e­tary gear units. In stain­less steel, they are qual­i­fied for trans­port, pack­ag­ing and fill­ing plants in the food indus­try. But also in the met­al­lur­gi­cal indus­try, the gal­van­ic indus­try, the vac­u­um sec­tor or the area of ​​satel­lite tech­nol­o­gy equip­ment, stain­less steel bel­lows cou­plings are prefer­ably installed.
