Brass Gears

Gears made of Brass, form a very important category of Gearing material. They combine the best qualities and give significant advantages in various types of gearing applications. Many a type of popular gears are successfully made out of brass. Some of them are highlighted here.

Types of Brass Gears
Some of the popular gears made out of Brass are discussed here:

Brass Internal Gears  
Typical specifications of some of the models of Brass internal gears with different pitches are given below. It must be noted that these specifications are product specific and can vary form for other models.

 

Internal Brass with 24 Pitch - 20° Pressure Angle - Face Width = 0.250"

 

Teeth	Pitch Diameter	O.D.	I.D.
36	1.500"	2.250"	1.450"
48	2"	2.750"	1.950"
72	3"	3.750"	2.950"
96	4"	4.750"	3.950"
144	6"	6.750"	5.950"

 

Internal Brass with 64 Pitch - 20° Pressure Angle - Face Width = 0.125"

 

Teeth	Pitch Diameter	O.D.	I.D.
64	1"	2.50"	0.98"
96	1.50"	2.0"	1.48"
128	2"	2.750"	1.98"
192	3"	3.750"	2.98"

 

Brass Miter Gears

• Typical Technical specification for Brass Miter gear sets that has:
• 48 Pitch
• 1:1 Ratio
• 20° Pressure Angle
• Bore Tolerance = ±0.0005"

Brass Racks and Pinions
Brass Racks and Pinions are quite useful in various types of shop and lab applications where it is intended to alter the rotary motion into a controlled uniform linear movement. These Brass Racks and pinions are easy to drill, tap or solder. 48 and 32 pitch racks are very common.

Brass Spur Gears
Brass Spur are very popular. These gears are used for transmission of motion and power between the two parallel shafts. The 20° pressure angle gears typically display a higher load carrying capacity than the ones with 14-½° pressure angle gears.

Brass Bevel Gears
Brass Bevel Gears are cut with typically a generated tooth form. These tooth form has a tooth bearing that is lengthwise localized. For a good performance, it is important that the Gears are pinned to a shaft by using a dowel or a taper pin.

Application of Brass Gears
Brass gears are often applied in clocks as they work soundly without any lubricant. An advantage of using brass gears is that due to constant meshing there is work hardening of their teeth. As a result of this there is little sign of wear.
