Pow­er Trans­mis­sion

The field of dri­ve tech­nol­o­gy includes all ele­ments for the trans­mis­sion of pow­er and motion between dif­fer­ent shafts. This trans­mis­sion enables, for exam­ple, an effec­tive speed con­ver­sion, the con­trol of motion sequences in indus­tri­al pro­duc­tion facil­i­ties or the gen­er­al trans­port of goods. The JÄGER Group offers a wide range of prod­ucts, espe­cial­ly for the area of belts and tapes made of rub­ber, plas­tic and var­i­ous mate­r­i­al com­bi­na­tions. In con­trast to chain dri­ves, which have a high degree of effi­cien­cy but do not allow any twist­ing with­in the sys­tem, belts and bands offer a sig­nif­i­cant­ly low­er noise devel­op­ment with low main­te­nance. For these rea­sons, they are used in mechan­i­cal and plant engi­neer­ing, the pack­ag­ing indus­try as well as in the equip­ment and agri­cul­tur­al machin­ery indus­try, among oth­ers.

Non-pos­i­tive dri­ve ele­ments

If the ener­gy in a tech­ni­cal sys­tem is trans­mit­ted by the fric­tion­al forces gen­er­at­ed between belts and dri­ving wheels, this is referred to as non-pos­i­tive dri­ve ele­ments. These are used wher­ev­er no syn­chro­nous move­ment of the ele­ments is required and the dri­ve may or should have slip. For this area we offer, among oth­ers, V‑belts, V‑ribbed belts and flat belts.

flat belts have a rec­tan­gu­lar cross sec­tion and, like all non-pos­i­tive dri­ve ele­ments, trans­mit ener­gy exclu­sive­ly via fric­tion­al forces. The con­tact sur­faces of the asso­ci­at­ed dri­ve wheels usu­al­ly have upward­ly curved or raised edges to pre­vent the belts from slip­ping off the pul­ley.

V‑belts are char­ac­ter­ized by their easy instal­la­tion and long ser­vice life and allow a high trans­mis­sion ratio. They are avail­able with sheathed or open-flank design and offer high­er trans­mit­table pow­er than flat belts.

V‑ribbed belts have indi­vid­ual ribs which run length­wise to the belt itself. The larg­er con­tact sur­face on the V‑belt pul­ley results in greater fric­tion and thus a high­er pow­er trans­mis­sion than with ordi­nary V‑belts. They are very well suit­ed for the simul­ta­ne­ous dri­ve of aux­il­iary units.

Pos­i­tive dri­ve ele­ments

If the ener­gy in a tech­ni­cal sys­tem is trans­mit­ted by belts and asso­ci­at­ed dri­ve wheels with form-fit pro­files, these are called form-fit dri­ve ele­ments. These are used when the dri­ve requires a syn­chro­nous move­ment which must have no slip. In this case, pow­er is not trans­mit­ted via fric­tion­al forces, but by the nor­mal force occur­ring between the belt tooth and toothed pul­ley. These include toothed belts and flat belts.

Toothed belts and flat belts made of rub­ber or PUR allow a low-noise trans­mis­sion of high torques with low space require­ments and weight. Due to their posi­tion­ing accu­ra­cy, these belts are also par­tic­u­lar­ly suit­able as finite ele­ments for lin­ear dri­ves. In addi­tion, tim­ing belts can effec­tive­ly per­form con­trol tasks between dif­fer­ent ele­ments of a sys­tem.
