Transmission components
Custom Gears, Racks & Worms
Custom transmission components manufactured to customer drawings, tooth specifications and assembly requirements.
A transmission component is defined by more than its teeth.

Define the Complete Component
Tooth geometry is only one part of the manufacturing definition.
Tooth Definition
- Module / diametral pitch
- Pressure angle
- Tooth count or starts
- Helix angle
- Lead / hand
Part Definition
- Bore / shaft
- Hub
- Keyway / thread
- Datums
- GD&T
- Accuracy standard
Mating Parts & Assembly Relationships
Define the interfaces that locate and connect the supplied component.
- Gear-to-gear engagement
- Gear-to-rack relationship
- Worm-to-wheel engagement
- Shaft / bore fit
- Mounting and datum relationship
This review focuses on the interfaces relevant to the supplied component. The customer retains responsibility for the overall assembly design and system validation.
Материалы, Heat Treatment & Finishing
Define material, treatment and finishing requirements for the supplied component.
Материал
- Material grade
- Supply condition
- Customer specification
Heat Treatment
- Hardness requirement
- Treatment sequence
- Post-treatment machining
Finishing
- Surface treatment
- Protected surfaces
- Final dimensional condition
Clearly identify whether critical dimensions apply before or after heat treatment or finishing.
Inspection & Acceptance
Tooth characteristics and ordinary dimensional features may require different verification methods.

Часто задаваемые вопросы
Answers to common questions about custom transmission components.
Which transmission components can you supply?
GPT Precision supplies custom gears, gear racks, worms, worm shafts and related toothed transmission components to customer specifications. Geometry, материал, accuracy requirements and manufacturing scope are reviewed for each inquiry.
Is tooth count enough to quote a gear?
Tooth count is one part of the component definition. A quotation normally requires the complete tooth specification together with bore, shaft or hub features, материал, quantity and relevant inspection requirements.
Should I provide the mating component?
Да, when it affects tooth engagement, выравнивание, fit or acceptance requirements. A mating-part drawing or assembly view can clarify the relevant interfaces; the information can be limited to the parts that affect the supplied component.
How should gear accuracy be specified?
Identify the applicable standard and required accuracy designation on the drawing or inquiry. Also state the specific characteristics, inspection records or functional checks required for acceptance.
Can you work from a sample?
A sample can provide useful reference information. Tooth geometry, состояние материала, tolerances and acceptance criteria still need to be defined. Include a controlled drawing where available, and clarify missing specifications before the manufacturing scope is confirmed.
Can heat treatment and finishing be included?
Heat treatment and finishing requirements can be reviewed as part of the component scope. Specify the required material condition, твердость, treatment or finish, and identify dimensions or surfaces with requirements after processing.
