描述

Screw gears, also sometimes called crossed helical gears, are helical gears used in motion transmission between non-intersecting shafts. The helical gears used in parallel beams have the same helix angle but opposite directions. For shaft angles other than the parallel, an arbitrary helix angle can be chosen. Assuming no profile shift, the intersecting angle of the shafts is the sum of the respective helix angles. Helical gears have point contacts and have lower efficiency than parallel or perpendicular shaft gears, and cannot transmit heavy loads.

Screw Gears: Technical Information

HZPT stock screw gears come in modules 1 ~ 4, 10 to 30 teeth, and four materials: S45C, SUS303, CAC702 (formerly A BC2), and MC nylon.

Selection Hints

Please select the most suitable products by carefully considering the characteristics of the items and the contents of the product tables. Before the final selection, it is also essential to read all applicable "CAUTION" notes. Since screw gears come in the right- or left-hand helix, include the letter "R" or "L" in the catalog number when you order.

1. Caution in Selecting the Mating Gears
Screw gears are used for offset shafts. Whether the shafts are paralleled offset or skewed offset depends on the helix hands of the mating gears.

Skewed Shafts	RH-RH or LH-LH
