Descrição
Helical Pinion
Helical pinions for rack drives and compact transmission assemblies, with bore, keyway, shaft or interface geometry made to the drive design.
Where this component fits
Helical pinions for rack drives and compact transmissions where the tooth form must match the rack and the mounting interface must fit the gearbox or shaft arrangement.
CNC axes, robot travel systems, cutting gantries and other helical rack drives are typical uses.
Technical specifications
The values below are the current catalogue and drawing-based scope already associated with this product family. Where a value is described as project-specific or “confirm drawing,” the released drawing remains the final technical reference.
| Forma do dente | Helical |
|---|---|
| Module / pressure angle | Match the rack or drawing |
| Hand / helix angle | Must match rack system |
| Mounting | Bore, keyed, spline, shaft or flange-style by drawing |
| Material/treatment | Selected for load and wear |
Selection should follow the mating component and the real duty
Module, pressure angle, helix angle and hand have to match the rack. Bore, keyway, spline, shaft or flange geometry then connects the pinion to the drive.
If a requested parameter is not yet fixed, provide the functional target and allow it to remain an open selection item. That is safer than locking the project to an assumed value that has not been checked against the mating component or machine.
Details that change the quotation
These fields help separate a standardizable configuration from a part that needs drawing-specific machining or inspection.
| Tooth data | Tooth count, module/DP, pressure angle and helix/shaft-angle data where applicable. |
|---|---|
| Mating component | Send the rack or mating gear data when mesh/contact/backlash depends on the pair. |
| Interfaces | Bore, keyway, spline, hub, shaft, flange and bearing/shoulder details. |
| Material/treatment | Drawing material, heat treatment, hardness and finish when controlled. |
| Accuracy | Gear-quality/tolerance and runout/concentricity requirements tied to functional datums. |
| Quantity | Prototype, production batch and annual demand if available. |
Process route follows the ordered specification
Manufacturing route depends on gear type, material, heat treatment and required tooth quality. Blank and datum machining, tooth cutting, heat treatment, finishing, bore/shaft features and final inspection should be planned as one sequence so later operations do not compromise the controlled geometry.
Material substitutions, heat-treatment changes and tolerance relaxations should be approved before production. For repeat orders, the approved drawing revision and any agreed inspection scope should remain attached to the order.
Fit, mounting and mating-part considerations
Pinion support and gearbox-output stiffness influence mesh stability. If the pinion is overhung, provide the drive layout so the interface can be reviewed in context.
For replacement work, send the existing part or assembly information as identification support, but confirm the production dimensions before release. Visual similarity is not a substitute for the tooth and interface data.
Inspection should follow the functional datums
Inspection should cover tooth geometry, bore/shaft/flange features, runout and the dimensions that locate the pinion relative to the drive.
If dimensional reports, material certificates or heat-treatment records are required with the order, identify them in the RFQ so they are included in the quality plan rather than requested after production is complete.
Products commonly reviewed together
Related components are shown as practical design companions, not as claims that every item is automatically compatible. Match the actual drawing and mating tooth data before ordering.
What to send for a useful quotation
Attach the latest drawing and state quantity, material, treatment, tooth data and critical inspection requirements. For rack-driven motion, add the axis duty and the mating pinion/gearbox details where available. STEP or DWG files help when secondary machining and interfaces are complex.

A useful quotation starts with the geometry and the operating context. Send the drawing, quantity and controlled requirements; for rack-driven axes, add travel, speed, acceleration, load and the mating pinion or gearbox information when available.
