This assembly includes a 70:1 gearbox and a 200mm handwheel for precise manual control. All parts are designed for seamless interfacing with the Vention ecosystem. Two kit options will be detailed: - A right angle gearbox attachment to allow for the input axis to be parallel with the output axis (MO-RM-007-1000) - An additional support for the output shaft to allow for increased payload (MO-RM-007-0010) ## **Assembly & Specifications:** ## **MO-RM-007-0000 Worm Gearbox Kit, 70:1 Ratio:** ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/Studio 857F-5153.png) ### **Kit Contents:** - 1x Worm Gearbox; - 1x Hand Wheel; - 1x Flanged Output Shaft Assembly; - 1x Gearbox Attachment Block; - 4x M8×18 screws; - 1x M6×16mm screw; - 6x M8×65mm screws. ### **Installation Instructions** - **Mount the plate**: Bolt the base plate to the extrusion structure. ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image(471).png) - **Secure the gearbox**: Fasten the gearbox to the mounting plate using either a ball-end Allen key, a ball-end t-handle or a stubby hex key to easily reach the bolts. | ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image(472).png) | ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image-1761922459469.png) | | --- | --- | - **Install the hand wheel:** Slide the hand wheel onto the input shaft of the gearbox. Fasten it using the provided washer and M6 × 16mm screw to prevent the hand wheel from sliding off. ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image-1761932313873.png) - **Line up the keys**: The end of the shaft has small raised rectangular parts called keys. They must be lined up with the matching grooves, or keyways, inside the gearbox opening. - **Slide it In**: Once those keys and grooves are aligned, push the shaft into the gearbox. The shaft can be slid in from either side of the gearbox, both orientations are supported. ![Should this have the aluminum plate with the handwheel that the render above has?](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image(417).png) - **Seat It firmly**: Continue pushing the shaft until the stepped section is fully seated. - **Lock It down**: Slide the provided shaft collar onto the exposed end of the shaft. The collar can then be secured by tightening the two fasteners to a torque between 9 and 11 Nm. This will ensure that the shaft cannot slide out of the gearbox assembly. - **Discard plate**: Once you are done, you will be left with one extra plate with the part number MO-RM-007-0002, this is normal and the plate is to be discarded. ### **Technical Specifications** | | | | --- | --- | | Ratio | 70:1 | | Maximum Output Torque* [Nm] (MA) | 58 | | Output Radial Load [N] | 4200 | | Output Axial Load [N] | 840 | | Maximum Payload with MO-RM-007-0010 [kg] | 453 | | Maximum Payload without MO-RM-007-0010 [Nm] (MB) | 400 | **Exceeding this output torque will reduce the life of the gears.

Remove and discard the 6 M6×60mm screws located around the input shaft of the worm gearbox. ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image-1761934076220.png) - **Install the adaptor plate:** Take the right angle adaptor plate and align the mounting holes with the matching set on the gearbox. Use the six M6 × 65mm screws provided in the kit to securely bolt the adaptor plate into position. Torque these screws in a star pattern to a torque between 9 and 11 Nm. ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/MO-RM-007-0002__2 Installation onto MO-RM-007-1000.png) - **Slide the right-angle gearbox on:** Carefully slide the right angle gearbox onto the exposed shaft of the gearbox kit. Use the four M6 × 20mm fasteners provided to secure the right angle gearbox to firmly to the adaptor plate. ![Diagram showing a right angle gearbox with labeled components and assembly instructions.](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/Asm Diagram(1).png) - **Install the hand wheel:** Slide the M16 washer onto the shaft of the 1:1 right angle gearbox. Then slide the hand wheel onto the shaft and fasten it using the provided washer and M5 × 16mm screw to prevent the hand wheel from sliding off. ## **MO-RM-007-0010 Self Aligning Rotary Jig Support:** ![](https://cdn.document360.io/3eee4d14-5ca0-4ea6-b426-1c19393e6a5e/Images/Documentation/image-1760645813675.png) This self-aligning support can be used to compensate for small shaft misalignment errors of less than **2.5 degrees** during installation. The support can be mounted to the Vention extrusion and accommodates the mounting pattern as the flange output shaft assembly. If the shaft is too far off-axis (over 2.5 degrees), the bearing seals may pop out. If this happens, they can be easily pressed back into the bearing by hand. ### Technical Specifications | | | | --- | --- | | Maximum Misalignment [degrees] | 2.5 | | Maximum Payload [kg] | 225 | | Maximum Rotation Speed [RPM] | 18000 | | Maximum Dynamic Radial Load [kN] | 14.3 | | Maximum Static Radial Load [kN] | 4.0 | | Worm Gearbox (MO-RM-007-0000) Maximum Payload with this support [kg] | 453 |
