Sprock­ets and Dri­ve Wheels

Dri­ve ele­ments are used in agri­cul­tur­al machin­ery as pos­i­tive dri­ve sys­tems. Dri­ving wheels or sprock­ets trans­mit the pow­er of the motor to the screen­ing belt. The JÄGER Group offers var­i­ous dri­ve wheels, which are avail­able in diam­e­ters from 120 to 800 mm.

The fol­low­ing four dri­ve options can be dis­tin­guished:

Dri­ving method Belt­ing pro­file Type of dri­ve wheel
Via the rods Low pro­files, dou­ble pro­files HS-RT‑Z
Via under belt cams High pro­files, dou­ble pro­files N
Via rods and cams High pro­files, dou­ble pro­files NC
Fric­tion dri­ve All pro­files FRD — HS – KW

Pro­duc­tion

Cast iron forms the heart of all dri­ve wheels. Most dri­ve wheels are sep­a­ra­ble to facil­i­tate assem­bly and replace­ment. The wheel halves form match­ing pairs and must not be mixed. Our dri­ve wheels are sup­plied drilled and keyed accord­ing to your spec­i­fi­ca­tions and, depend­ing on require­ments, the type and size of the key­ways are cut accord­ing to Ger­man DIN (met­ric) or cus­toms stan­dards. The fric­tion dri­ve types FR, FRD and KW can be used with any belt type and pitch.

HS Dri­ve wheels The dri­ve teeth grip direct­ly between the down­ward curved rod. The dri­ve belt is sup­port­ed by the lat­er­al cage fin­gers to pre­vent wear in the tooth root and to ensure a con­stant pitch cir­cle diam­e­ter through­out its life. The basic length of the flights or the rod cov­er require free paths for the sprock­et.
3TB Dri­ve wheels The dri­ve tooth­ing works direct­ly against the upward curved, i.e. con­vex, rod. They are often used in con­vey­or sys­tems with one or more cen­tral belts to which the rods are attached with clamps or clamps. The rods with mid­dle clamps are usu­al­ly posi­tioned high­er and there­fore require a larg­er pitch cir­cle diam­e­ter. 3 TB dri­ve wheels are found on HS, RT, NC and Z dri­ve types.
RT Dri­ve wheels The actu­a­tor of the RT type is sim­i­lar to the type HS, but has a sol­id side ring sup­port flange. RT units offer a per­fect pitch cir­cle diam­e­ter for the heav­i­est loads. With this sprock­et type, it is pos­si­ble to mount a scraper to pre­vent the accu­mu­la­tion of dirt.
Z‑Typ Dri­ve wheels With the Z‑type, the riv­et rods are locat­ed in the low­er area of the tooth form. The wheels are used for light appli­ca­tions.
NC Dri­ve wheels The NC dri­ve wheel is a com­bi­na­tion of a HS and N dri­ve wheel and was devel­oped for high belt pro­files. For opti­mum pow­er trans­mis­sion, this dri­ve wheel is dri­ven via rods and cams.
N Dri­ve wheels The N dri­ve wheel is designed for cam pro­file belts. The dri­ve fin­gers engage in the cams of the belt and dri­ve it. Since there is no con­tact with the rods, there is no wear of the rods, which makes this type of sprock­et run very smooth­ly. The N‑type is the pre­ferred dri­ve sys­tem for Silen­tium Dri­ve appli­ca­tions.
