2. Reducer pinion type:
Common types of reducer pinion include:
(1) straight pinion: the rack and pinion are parallel to the axis, and the tooth surface is linear, which is suitable for high-speed deceleration transmission.
(2) helical pinion: the rack and pinion are at a certain Angle with the axis, the tooth surface is slanted, and it has smooth transmission characteristics, which is suitable for applications with low noise and high vibration requirements.
(3) conical pinion: the pinion rack and axis intersect at a point, the tooth surface is conical shape, suitable for transmitting the axis of rotation is not parallel.

3. Reducer pinion material:
Reducer pinion commonly used materials are:
(1) Steel: high strength, hardness and wear resistance, suitable for high load and high-speed transmission system.
20CrMnTi (China standard), 8620 (USA standard)
40Cr (China standard), 5140 (USA standard)
42CrMo (Chinese standard), 4140 (American standard)
(2) Cast iron: high impact resistance and noise absorption capacity, suitable for low speed and medium load applications.
HT200 (China standard), FC200 (Japan standard)
HT250 (China standard), FC250 (Japan standard)
(3) Brass: good corrosion resistance and low noise characteristics, suitable for high precision requirements and low speed transmission system.

4. Reducer Pinion parameter table:
The following are the numerical ranges of common pinion parameters for designing and selecting the right pinion:
| Parameter | Description | Reference value |
| Module | Size parameters of the rack and pinion | 1.0 mm - 2.0 mm |
| Number of teeth | The number of teeth of the pinion | 15 - 30 |
| Pressure Angle | The pressure Angle at which the gear engages | 15° - 25° |
| Tooth width | The width of the pinion rack | 10 mm - 15 mm |
| Normal displacement | The amount of axial movement of a gear when engaged | 0.1 mm - 0.5 mm |
| Spiral Angle | Bevel Angle of a pinion | 20° - 40° |
| Hardness | Surface hardness of pinion | HRC 40 - HRC 50 |
| Tooth surface roughness | Roughness of pinion tooth surface | Ra 1.2 μm - Ra 2.0 μm |
By selecting the appropriate value within the parameter range according to the actual requirements and design standards, the transmission efficiency and reliability of the reducer pinion can be ensured.

5. Summary:
Reducer pinion as one of the important transmission components in the reducer, there are many types to choose from, including straight pinion, helical pinion and bevel pinion. Depending on the requirements of the application, the pinion can be selected from different materials such as steel, cast iron or brass to meet the required strength, wear resistance and noise control. In the design and selection of pinion, refer to the numerical range in the parameter table, according to the modulus, number of teeth, pressure Angle, tooth width, normal displacement, helix Angle, hardness and tooth surface roughness and other parameters, can ensure the performance and reliability of the pinion.
