Miniature couplings create precision

The minia­ture cou­plings from Jakob are designed as ser­vo com­pen­sat­ing cou­plings for the off­set or the axi­al dis­place­ment of two axes. For the dif­fer­ent appli­ca­tions such. For tachographs, NC-axes, step­per motors, poten­tiome­ters, robot dri­ves, lin­ear units, han­dling devices, angle encoders or ser­vo dri­ves, var­i­ous designs are avail­able. The shaft is fas­tened by clamp­ing ring or thread­ed pins. The minia­ture cou­plings are avail­able as bel­lows cou­plings, elas­tomer cou­plings or cross slide couplings.

As bel­lows cou­plings they are absolute­ly play and main­te­nance-free and designed for the trans­mis­sion of high speeds. They are char­ac­ter­ized by a high tor­sion­al rigid­i­ty and a low mass moment of iner­tia. Thus, the angu­lar true, back­lash-free trans­mis­sion of the rota­tion­al move­ment is pos­si­ble. The com­pact elas­tomer minia­ture cou­plings as plug­gable, back­lash-free and flex­i­ble shaft cou­plings can com­pen­sate for slight­ly larg­er shaft off­sets. They are elec­tri­cal­ly insu­lat­ing and have a good vibra­tion-damp­ing behavior.

The advan­tages of the also elec­tri­cal­ly insu­lat­ing cross slide cou­pling are in addi­tion to a very short length, a large dis­place­ment capac­i­ty, low restor­ing forces, the plug­ga­bil­i­ty and a result­ing arbi­trary com­bi­na­tion of dif­fer­ent bore diameter.

In nor­mal oper­a­tion, the cou­plings are main­te­nance-free and with prop­er instal­la­tion, the Jakob minia­ture cou­plings achieve an almost unlim­it­ed ser­vice life. Due to the proven mod­u­lar sys­tem and the stor­age of the com­mon diam­e­ters short­est deliv­ery times are guaranteed.
