Acme Gear Co., Inc.
Where Precision Meets Performance
Acme Gear Product Lines
Acme Gear has a robust offering of products listed below to meet any need you may have. In addition to our base product line we offer custom job shop work for that unique need that may arise from time to time. Our engineers are highly skilled at reverse engineering and are eager to tackle your most difficult request.
Helical Gear
Helical Gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement.The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix.
Acme's size range and capabilities are outlined below:
Diametral Pitch:
Max: 1
Min: 48
Face Width: 20"
Unground Tooth: O.D. 60"
Ground Tooth:
O.D. 60"
Spur Gears
Spur gears have straight teeth, and are mounted on parallel shafts. Spur gears are the simplest and most common type of gear. Their general form is a cylinder or disk. The teeth project radially, and with these "straight-cut gears", the leading edges of the teeth are aligned parallel to the axis of rotation.
Acme's size range and capabilities are outlined below:
Pitch Diameter:
Max: 1
Min: 48
Facewidth: 20"
Unground Tooth: Outside Diameter 60"
Ground Tooth: Outside Diameter 60"
Worm Gears
Worm gears are used when large gear reductions are needed. It is common for worm gears to have reductions of 20:1, and even up to 300:1 or greater. The worm can easily turn the gear, but the gear cannot turn the worm. This is because the angle on the worm is so shallow that when the gear tries to spin it, the friction between the gear and the worm holds the worm in place.
Acme's size range and capabilities are outlined below:
Pitch Diameter:
Max: 60"
Min:0.75"
Bull Gears
Bull gears are a toothed driving wheel that is the largest or strongest in the mechanism. A gear or sprocket that is much larger than the others in the same power train.
Acme's size range and capabilities are outlined below:
Pitch Diameter:
Max:48
Min:1
Face Width:20"
Ground: O.D. 60"
Cut: O.D. 60
Bevel Gears
Bevel gears are useful when the direction of a shaft's rotation needs to be changed. They are usually mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well.The teeth on bevel gears can be straight, spiral or hypoid. Straight bevel gear teeth actually have the same problem as straight spur gear teeth -- as each tooth engages, it impacts the corresponding tooth all at once
Acme's size range and capabilities are outlined below:
Maximum Pitch Diameter: 36"
Diametral Pitch: Up to 1
Face Width: 8"
Internal Gears
An actuator consisting of two interlocking gears. One gear with external teeth is housed within a gear with internal teeth.Acme's size range and capabilities are outlined below:Diametral Pitch: 2.5 - 48Internal Diameter:36" Cut42" Ground
Acme's size range and capabilities are outlined below:
Diametral Pitch: 2.5 - 48
Internal Diameter:
36" Cut
42" Ground
Pinions
Pinion gears are used to convert rotation into linear motion.
Acme's size range and capabilities are outlined below:
Diametral Pitch:
Min: 1
Max: 48
Face Width: 20"
Length: 72"
Splines
Shafts are a bar, usually cylindrical, for supporting or transmitting motion to a wheel, pulley, gear, cam, etc
Acme's size range and capabilities are outlined below:
12" x 62"
Sprockets
A sprocket is a profiled wheel with teeth that meshes with a chain, track or other perforated or indented material. It is distinguished from a gear in that sprockets are never meshed together directly, and from a pulley not usually having a flange at each side.
Acme's size range and capabilities are outlined below:
Maximum Diameter: 60"
