Tests & Measurements

This is a two-station assembly system for pinion shaft to the housing assembly for a line of wheel loaders for the construction industry. The first station is a servo pressing station which locates the cups in the pinion housing and the bearing cones on the pinion gear shaft. A second station tightens a nut on the pinion shaft to remove the endplay and set preload on the tapered roller bearings. Rolling torque is measured automatically to verify proper bearing preload. Each station uses manual material handling but assembly operations are electronically controlled to assure each step is completed before the operator can move on to the next. Bearing preload is measured through shaft rolling torques which are critical for product quality.
