Many of these features are highlighted in the sections below. ### Input Block - Mounting Holes {% tabs %} {% tab title="Front Side" %} The Input Block includes four #10-32 tapped holes, highlighted below, for custom mounting options. These holes follow the [1/2" Pitch Spacing Standard ](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing)used across our product line, allowing for seamless integration with other WCP components.

{% endtab %} {% tab title="Back Side" %} The Input Block features two #10-32 clearance holes, highlighted below, that support motors with a 2" bolt circle mounting pattern. Alternatively, these holes can be used to directly mount the Input Block by capturing #10-32 nuts in the integrated pockets, allowing it to be securely attached to a surface while following the [1/2" Pitch Spacing Standard](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing). {% hint style="warning" %} The Nut Pocket feature can **ONLY** be used if direct [Motor Mounting](/welcome/gearboxes/planetaryx/assembly-instructions/planetaryx/motor-mounting.md) will not be done and an Input Coupler is going to be used during the [Shaft Installation](/welcome/gearboxes/planetaryx/assembly-instructions/planetaryx/input-coupler-installation.md) process. {% endhint %}

{% endtab %} {% tab title="Side Mounting" %} The Input Block features two distinct Side Mounting hole patterns with #10-32 tapped holes, highlighted below. These threaded holes can then be used to mount the Input Block while following the [1/2" Pitch Spacing Standard](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing). {% hint style="info" %} Due to each stage of the Planetary X being 0.75" thick, the hole highlighted in orange in the image below is intentionally offset by 0.25". This ensures that at least one hole always aligns with the 1/2" Pitch. For Example: * **Odd number of stages**, the **center hole (highlighted in ****Orange****)** will align to the 1/2" Pitch. * **Even number of stages**, the **two outer holes (highlighted in ****Blue****)** will align to the 1/2" Pitch. {% endhint %}

{% endtab %} {% endtabs %} ### Input Block - Bolt Circles The Input Block features four standard FRC motor bolt circle patterns, providing compatibility with virtually any legal FRC motor. This eliminates the need for additional adapter plates, making motor integration quick and straightforward.

### Input Couplers The PlanetaryX is designed to support both Direct Motor input and 1/2" Hex Shaft Input through the use of the couplers shown below. {% tabs %} {% tab title="Female Input Coupler" %} The Female Input Coupler features a 1/2" deep hex bore designed to accept standard 1/2" hex shafts. It includes a #10-32 clearance hole, allowing a bolt to pass through and secure the shaft in place. This coupler provides a simple and effective way to transmit torque while maintaining axial retention.

{% endtab %} {% tab title="Male Input Coupler" %} The Male Input Coupler features a 1.5" long, 1/2" hex shaft with a #10-32 blind tapped hole that is 3/4" deep. This coupler is designed to transfer torque efficiently while providing a secure fastening point for axial retention.

{% endtab %} {% endtabs %} ### Output Block - Mounting Holes {% tabs %} {% tab title="Front Side" %} The Output Block includes six #10-32 tapped holes on a 2" Bolt Circle, highlighted below, for custom mounting options.

{% endtab %} {% tab title="Side Mounting" %} The Output Block features two distinct Side Mounting hole patterns with #10-32 tapped holes, highlighted below. These threaded holes can then be used to mount the Input Block while following the [1/2" Pitch Spacing Standard](/welcome/frc-build-system/system-standards.md#id-1-2-pitch-spacing).

{% endtab %} {% endtabs %} ### Output Block - Hex Socket {% tabs %} {% tab title="Front" %} The 1/2" Hex Socket features a standard 1/2" hex output bore, providing seamless compatibility with the WCP 1/2" hex ecosystem and other common FRC components. This also makes it easy to integrate the PlanetaryX into a variety of robot mechanisms. The #10-32 clearance hole, highlighted below, is used to secure the output shaft and prevent the 1/2" Hex shaft from backing out over time due to vibration or repeated cycles. {% hint style="warning" %} If the bolt is threading into the Output Shaft, it must be inserted through the clearance hole from the backside and tightened against the shaft to maintain axial retention during operation. {% endhint %}

The 1/2" Hex Socket also features six 3mm holes on a 0.75" Bolt Circle for the included 3mm dowel pins, as shown below. This optional interface increases torque capacity by providing additional resistance to rotational shear.

{% endtab %} {% tab title="Back" %} The Back Side of the 1/2" Hex Socket features an integrated pocket that is meant to capture a #10-32 nut. This pocket allows for a quick and easy removal or swap of the Output Shaft. {% hint style="warning" %} The Nut Pocket feature is intended to be used only when a bolt is long enough to go through the entire shaft length, through the Hex Socket fully thread into the captured #10-32 nut. {% endhint %}

The image below demonstrates how the integrated nut pocket can be used to secure the output shaft from the outside, allowing for quick and easy shaft removal or replacement. {% hint style="success" %} Refer back to [Step 2 of the 1-3 Stage Assembly](/welcome/gearboxes/planetaryx/assembly-instructions/planetaryx/1-3-stage-assembly.md#step-2) section for assembly information. {% endhint %}

{% endtab %} {% endtabs %} ### Encoder Compatibility The integrated bolt circle on the Output Block provides a simple mounting solution for the WCP ThroughBore Encoder as shown below. {% hint style="warning" %} Do not overtighten the Throughbore Encoder mounting bolt. Excessive torque may deform or compress the encoder housing {% endhint %} {% hint style="info" %} When face mounting the PlanetaryX with the Through Bore Encoder, use 3/4" L spacers (WCP-0217) between the mounting surface and the PlanetaryX face. {% endhint %} {% tabs %} {% tab title="ISO View" %}

{% endtab %} {% tab title="ISO Exploded View" %}

{% endtab %} {% endtabs %} ## PX 180 Degree Gearbox ### Bolt Circles The PX 180 Degree Gearbox Plate features two bolt circle patterns, supporting motors with either a 2" or 1.375" bolt circle. This allows for compatibility with a wider range of motor mounting options.

### Mounting Holes The PX 180-Degree Gearbox Plate features six #10-32 clearance holes for mounting directly to the Planetary X, along with two #10-32 tapped holes that can be used for additional mounting configurations.

### C-C Spacing The PX 180-Degree Gearbox features a 2.552" center-to-center spacing, as shown below. This spacing is designed to support both gear and belt-and-pulley configurations, giving teams the flexibility to choose the method that best fits their mechanism. #### Gear Compatibility The PX 180-Degree Gearbox center-to-center spacing is designed to support a 102T gear spacing configuration.

#### Pulley Compatibility The PX 180-Degree Gearbox center-to-center spacing is designed to support belt-and-pulley configurations, allowing for compact and efficient power transmission. An example setup is shown below.
