Spur gears are the most easily visualized common gears that transmit motion between two parallel shafts. Because of their shape, they are classified as a type of cylindrical gears. Since the tooth surfaces of the gears are parallel to the axes of the mounted shafts, there is no thrust force generated in the axial direction. Also, because of the ease of production, these gears can be made to a high degree of precision. On the other hand, spur gears have a disadvantage in that they easily make noise. Generally speaking, when two spur gears are in mesh, the gear with more teeth is called the “gear” and the one with the smaller number of teeth is called the “pinion”.
The unit to indicate the sizes of spur gears is commonly stated, as specified by ISO, to be “module”. In recent years, it is usual to set the pressure angle to 20 degrees. In commercial machinery, it is most common to use a portion of an involute curve as the tooth profile.

Just as the name suggests, stock gears are defined as gears which are always stocked.
When the gears of machines in operation break, the person in charge of the maintenance of the machines can immediately replace them if gears of the same shape are in stock at a supplier’s base. Also, for the machine designers, when designing machines they can check the specifications of already designed stock gears and adopt stock gears as the gears to use when the specifications of said stock gears match the needs of the machine they are designing. In such cases there is no need for the machine designers to design new gears, and furthermore it is possible to procure the small amount of gears needed to produce a prototype of the machine quickly and affordably.

A worm gear is a type of staggered shaft gear that transmits motion between two shafts that are neither intersecting nor parallel. Even though it is compact it can provide a large speed reduction.
A worm gear is a thread cut into a round bar, and a worm wheel is a gear that meshes with the worm at a shaft angle of 90 degrees. The set of a worm and worm wheel is called a worm gear.
Its history is so old that its existence is described by Archimedes in around 250 BC.
There are roughly two types of worm gears.
One is a cylindrical worm that meshes with a worm wheel as a pair to form the "cylindrical worm gear".
The other is the "drum-shaped worm gear" which is a pair consisting of a drum-shaped worm and a worm wheel.
The latter type is also called "throated worm gear".

Helical gears are one type of cylindrical gears with slanted tooth trace. Compared to spur gears, they have the larger contact ratio and excel in quietness and less vibration and able to transmit large force. A pair of helical gears has the same helix angle but the helix hand is opposite.
When the reference section of the gear is in the normal plane, by tilting the hobbing tool, the spur gear hobbing machine and hobbing tool can be used to produce helical gears. Because of the twist of teeth, their manufacturing has the disadvantage of more difficult production.

The standard definition of a Bevel Gear is a cone-shaped gear which transmits power between 2 intersecting axels.
Looking at bevel gears from the differences in helix angles, they can be generally classified into straight bevel gears, which do not have helix angles, and spiral bevel gears (including zerol bevel gears), which do have helix angles. However, because of the fact that manufacture facilities for straight bevel gears are becoming rare and the fact that straight bevel gears teeth cannot be polished, making spiral bevel gears which can be polished superior in terms of noise reduction, spiral bevel gears are likely to become more common in the future.

Internal gear is a gear with its teeth cut in the internal surface of a cylinder and meshes with spur gears.
In its manufacturing, because of its shape, the usual hobbing machine used in spur gear production cannot be used. Generally it is made with gear shaper (or gear shaping machine) equipped with a pinion cutter. More recently, the efficiency of internal gear cutting has been improved by a different process called skiving.

Miter gears are one type of bevel gears where the two rotational axes intersect. When speaking of narrow definition of bevel gears with ability to increase or decrease speed, miter gears do not have that ability due to the pair’s same number of teeth. Their purpose is limited to the change in transmission direction. Because they are a type of bevel gears, the basic characteristic of bevel gears exist such as presence of gear forms of straight cut, spiral cut and zerol types.
Also, because the shafts can be set to any angle, there are miter gears with non-90 degree (non-perpendicular) angle called angular miter gears. KHK is capable of producing angular miter gears with shaft angles in the range of 45 to 120 degrees.
