Pinion Preload Machine

About Us

ASTA Technologies design and manufacture high precision backlash setting machine for eliminating backlash in differential. This machine provides precise method to move the crown and pinning through a NUT assembly. A precision encoder is mounted with pneumatic Collet arrangement to measure the backlash.

One of the backlash setting machine is installed at Carraro, Pune.

Specifications

The project includes the design, concept building & development of Assembly Machine for the Driveline differential of an earth-moving vehicle.

After setting the preload and arranging the crown and bevel in the differential housing sets the desired backlash.

The backlash setting procedures includes the movement and fixing of the crown and pinion contact through a NUT assembly.

The backlash is measured by locking the differential bush through a pneumatic Collet arrangement and turning the coupled wheels and measuring the backlash through the encoder system.

The backlash of the system can be set and measured at an accuracy of 10 micron.

After Setting the Backlash in the differential, Final preload of the system is set and measured through an inline torque cell.

Hardware used: PCI cards, LabVIEW 8.5 software, Torque sensors, encoders and servo motors were used for this machine development.

The Setting parameters of Backlash and Final Preload value are set from SAD ( network from Pinion Preload Machine), The reports are further saved on SAD.
