Ka-Wood Gear & Machine

For the last century, Ka-Wood Gear & Machine has been manufacturing precision gear products that include spur, helical, and worm gears, as well as producing spline shafts, racks, timing belt pulleys, and sprockets for a vast array of  industries.

It’s not every company that can boast it’s been in business for a century, and that milestone is not something the owners of Ka-Wood Gear & Machine take for granted. Those 10 decades were filled with a lot of ups and downs for the gear industry, but being able to change with the times while […]

Optimization of asymmetric tooth root generated with protuberance hob

Demonstrating the construction and optimization of the tooth root fillet while leaving required grinding stock on the involute tooth flanks.

The Direct Gear Design [1] method optimizes various parameters and elements of gear tooth geometry to achieve the required gear-drive performance. One such critical element of the tooth profile is the root fillet. Previous publications had considered asymmetric tooth root fillet optimization assuming the tooth involute flanks and root fillets are processed (machined) simultaneously. However, […]

Long hob cost savings over the length of a job

Comparing the influence of geometric variations in physical hob size on tool life; specifically, the overall length of the hob.

Manufacturers consider many factors when shopping for a gear hob solution: What material is being cut? What is the pitch of the part? Will the hob be delivered on time, and what will it cost? Unless the job is hot and lead time is critical, the cost of the tool tends to be the deciding […]

Conjugate Action Law in Intersected-Axes Gear Pairs and in Crossed-Axes Gear Pairs

Dealing with geometrically-accurate gears with parallel-axes gear sets, intersected-axes gear sets, and with crossed-axes gear sets.

The article deals with the kinematics and the geometry of geometrically-accurate gearing (with perfect gearing). Considered at the beginning for parallel-axes involute gearing, conjugate action law later on is formulated for intersected-axes gearing (straight bevel gearing, spiral bevel gearing, and so forth), as well as for crossed-axes gearing (hypoid gearing, spiroid gearing, worm gearing, and […]

Determining tooth thickness of various gear types – Part III

How to calculate the nominal values of over-pin or ball measurement of teeth for various types of gearing.

In order to determine the tooth size of a gear after taking into account the backlash allowance, you first must determine what the nominal tooth thickness should be. There are three methods for determining this value: chordal tooth thickness measurement, span measurement, and over-pin or ball measurement. For this article, we will discuss measurement over […]

Back to basics – Toughness testing of material

The Charpy impact test determines the amount of energy absorbed by a material during fracture. 

In the last series of articles, we discussed hardness testing and tensile testing. In these applications, the loading is a static load over a short time duration. All the forces on the body are in equilibrium. However, in many applications, a static load is not what the part experiences in service. In dynamic loading, the […]

The challenges of generic deburring vs. CAVF deburring

CAVF allows use of HDNA media, which has a low attrition rate, keeping its shape and size much longer and reducing fear of media lodging problems.

Relative to gear hobbing, shaving, and/or post heat-treat grinding to generate accurate tooth morphology there may come a time wherein vibratory deburring is a requirement to remove adherent burrs.  What are the advantages and disadvantages of generic deburring as opposed to chemically accelerated vibratory finishing (CAVF), and why would you consider one option compared to […]
