Advantages Provided By Gear Shaping Cutters

In production, gear shaping cutters are only one of many possible processes that might use to create the same gear. Gear hobbing is making teeth in a backpack or spline using a specialized milling machine fitted with a hobbing tool. Even though the specifics of each job are different, hobbing packs offer the following five advantages:

  • Speed

Gear hobbing is relatively more rapid than other processes involved in making gears. Keeping the machine running requires less attention because of the machine’s ease of use. Some gears may be assembled from numerous separate parts and hobbed as a unit.

  • Precision

Hobbing has the potential to be an exact technique that produces high-quality gears if done correctly. A hobbing machine, however, is something that only some can use.

  • Flexibility

Different hobs and hobbing machines allow the production of an almost infinite number of customized gear sets.

  • Versatility

While spur gears are the most common form of gear to have its teeth cut off, other gears such as cycloid gears, helical gears, worm gears, ratchets, splines, and sprockets may also be hobbed.

  • Output

Gear hobbing is a fast method of producing gears, allowing you to increase output and fulfill more orders in a shorter amount of time.

When determining which production method is best for your gears, it is essential to consider the task’s unique specifications. Contact their gear manufacturing experts to get a quote or determine whether hobbing is right for you.

To cut gear teeth, a rack-shaped cutter

For this method, we use a rack-shaped cutter, also called a rack-type blade, to make precise gear cuts—the notion in Figure for clarity. The technique is similar to that used to manufacture a gear-type cutter.

The rack-type cutter rotates the gear blank slowly while moving in a vertical reciprocating motion. Only the downward stroke does the actual cutting; the upward movement is only a return stroke. The main difference between this method and the previous one is that after the rack is completely exhausted, the gear blank is restored to its original position before a fresh run of gear cutting may begin. Thus, this process is periodic for more giant gears with many teeth all over their circumference.

Gear sizing has several advantages:

The procedure’s primary advantages are as follows:

  • Decreased manufacturing lead time; well suited for high-volume production of medium- to large-sized gears.
  • Except for worm gears and wheels, several bags may be manufactured.
  • When cutting gears, may maintain precise tolerances.

It is practical to keep the gear tooth profile accurate and repeatable

For a given value of the gear tooth module, you may use a single gear shaper cutters regardless of the number of teeth in gear. Reciprocating at a high enough speed to remove material from the workpiece’s face necessitates a blade that is supplied progressively in a radial direction to dive to the proper tooth depth. A relieving mechanism lets the cutter clear the work on a non-cutting or return stroke.

Feeding the cutter to its maximum depth and gently rotating the workpiece in a perfect ratio to the number of teeth on each side using a sequence of gears, including changing gears, creates the continuous generation action. The workpiece is the driven part, and the cutter is the driving gear; however, an external connection in the gear train affects the accuracy of motion transmission.
