Meaning and Definition
A type of bevel gear where the two meshing gears have the same number of teeth and intersect at a 90-degree angle, used to change the direction of a drive shaft.
In mechanical engineering, a gear designed to transmit power between intersecting shafts at a right angle, with a 1:1 ratio, often used in differentials, hand drills, and other machinery requiring a directional change without speed alteration.
Dialectal Variation

Differences
Spelling: UK 'mitre gear', US 'miter gear'. The technical meaning and application are identical.
Connotations
None beyond the spelling difference. The term is purely descriptive and technical.
Frequency
Equally low frequency in both dialects, confined to engineering texts, manuals, and discussions.

Common Mistakes When Using “miter gear”
- Misspelling as 'mighter gear', 'mitre gear' (US context) or 'miter gear' (UK context).
- Confusing with a 'bevel gear' which can have any ratio, not strictly 1:1.
- Using it as a general term for any gear that changes direction.
FAQ
Frequently Asked Questions
All miter gears are bevel gears, but not all bevel gears are miter gears. A miter gear is a specific type of bevel gear where the two gears are identical (1:1 ratio) and intersect at 90 degrees.
In devices requiring a right-angle change in shaft direction without speed change, such as hand drills, mechanical clocks, some differentials, and various industrial machinery.
The name comes from the 'miter' joint in woodworking, where two pieces are cut at equal angles (typically 45°) to form a 90° corner, analogous to the 45° pitch angle of each gear tooth.
No, by definition, miter gears have the same number of teeth, resulting in a 1:1 speed ratio. If the tooth counts differ, it's a standard bevel gear set.
A type of bevel gear where the two meshing gears have the same number of teeth and intersect at a 90-degree angle, used to change the direction of a drive shaft.

Memory Aids
Mnemonic
Imagine a MITER saw cutting a 45-degree angle; two such angles meet to form a 90-degree corner, just like two miter gears meeting at a right angle.
Conceptual Metaphor
A HANDSHAKE AT A CORNER: Two equal partners meeting and changing direction together without one dominating the other (1:1 ratio).
