7,306. 4. 0. May 26, 2013. #2. Helical gears are stronger than straight cut gears, assuming similar size and materials. More surface area to engage. The helical gear weakness is axial loading, which I'm sure is going to be tolerated differently by different transmissions. I would look for input from dedicated off-roaders using your parts.
The helical bevel gear refers to the tooth line on the crown wheel of the production shape, and is a straight bevel gear that does not pass through the top of the cone. There are orthogonal helical bevel gears and spiral bevel gears. Straight bevel gear pair has relatively few teeth in the transmission at the same time, which is easy to produce ...

Helical Gears have teeth that are set on an angle to the gear axis. Since the teeth engage more gradually, they have a smoother and quieter operation than spur gears. Helical gears also have greater tooth strength and a higher load carrying capacity. Further, helical gears can transmit power between either parallel or non-parallel shafts, while ...

A helical gear doesn't have a single best pressure angle, but it does have a center play. Helical gears have a smaller cross section, which affects the radius of curvature and normal force. As the helix angle increases, the contact ratio decreases. This reduces the contact ratio and increases the length of the gear contact line.
Request Custom or Modified Product. Helical cut gears are similar to spur gears with their teeth cut at an angle. The most popular helical gear design is 45 degrees. Helical cut gears can have a right hand or a left-hand gear helix. When 45° helical gears of the opposite hand operate together they will turn parallel shafts in opposite rotation.

Boston Gear's stock helical gears are manufactured in both right- and left-handed configurations with an industry standard 45° helix angle to transmit motion and power between non-intersecting shafts that are parallel or at 90° to each other. Helical gears can be used in a variety of applications since they can be mounted on either parallel or on 90° non-intersecting shafts.

Helical gears and spur gears are two of the most common gear types and can be used in many of the same applications. Spur gears are simple and inexpensive to manufacture, but helical gears offer some important advantages over spur gears. The teeth of a helical gear are set at an angle (relative to axis of the gear) and take the shape of a helix.
