Transmission drive

Spare parts for drive transmissions for combine harvesters Niwa

Single-circuit variator enables stepless change speed combine within one of gear.

The variator includes

• drive belt tensioner
• master unit (with the movable and fixed pulleys)
• Slave unit (fixed pulley)

The principle of operation is based on the change in gear ratio HZ unilateral actions that acting on the hub of mobile driving unit pulley moves it.

The clutch is necessary to short-term separation and transmit torque from the variator speed of the movement at the checkpoint. Coupling stands on the primary shaft of a check point and includes a master, slave and push drives with the release lever and release bearing. Enabling is performed using GC, which pusher and a fork connected to the lever. At the same time during power-MS pusher activates the traction and tormozka lever.
