Gear Helical Pinion – RA1028922

Angled teeth set this helical pinion apart from a straight-cut gear, letting each tooth engage the mating gear gradually rather than all at once, which is what makes the drive run smoother and quieter through a Raymond lift truck's drivetrain. As the smaller, driving member of the mesh, the pinion turns the larger gear to pass engine or motor torque on through the transmission.

The helical form keeps more than one tooth in contact at any moment, so the load spreads across several teeth instead of hammering onto one, which both carries torque steadily and cuts the whine that straight-cut gears produce. A pinion that has chipped, pitted, or worn its tooth profile transmits load roughly and noisily, and replacing it returns the drivetrain to smooth engagement. Match the tooth count, pitch, and helix angle to the pinion being replaced, since the pinion must mesh exactly with its mating gear to run true.
