Discussion Overview

The discussion revolves around building a small lifting device using a Kohree motor to lift a weight of 10 pounds a few inches. Participants explore various mechanical solutions, including the use of pulleys and gears, while considering the constraints of size and cost.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant suggests that the Kohree motor should be sufficient for the task.
  • Another participant inquires about the setup, asking for a schematic and details about the motor shaft connection.
  • Concerns are raised about visualizing how to lift the weight horizontally with the motor mounted horizontally.
  • Participants discuss the potential use of pulleys, key screws, and gearboxes as part of the lifting mechanism.
  • One participant shares a link to a project that offers solutions for coupling a motor to a shaft, suggesting it may provide relevant insights.
  • There is a request for simpler solutions or additional ideas from the community.

Areas of Agreement / Disagreement

Participants generally agree on the suitability of the motor, but there is no consensus on the best method to connect the motor to the weight or how to achieve the lifting mechanism effectively. Multiple approaches and ideas are presented without resolution.

Contextual Notes

Participants express uncertainty regarding the feasibility of fitting the lifting mechanism within specific dimensions, and there are unresolved questions about the mechanical setup and connections needed for the motor.

Who May Find This Useful

TL;DR
Lift from a horizontal motor shaft
I am trying to build a device that will push up a small piece of wood (attached to a weight) from its’ base to support 10 pounds. I would only need to move 1 to 2 inches. My device would be about 1 - 2 feet wide. I would use perhaps this motor:

Kohree 12V DC Gear Motor 30RPM Small High Torque Electric Motor 37mm GearBox

I would want to mount the motor horizontally but this is where my problem begins. How could I move the wood weight up horizontally at a reasonable price? Perhaps using gears? I cannot use an actuator because the price would be prohibitive.

I was wondering if anyone could impart a rough solution. Even just a few keywords or concepts could help me jump start my mind to the next level.

Welcome, reg326j :cool:

I believe that motor will be sufficient.
Could you post some basic schematic of the set up?
Do you have a pulley with a key screw that will fit that shaft?
Do you have a base that will fit the exterior diameter of the gear box clamping it by friction?

I have found this about your motor:

Note that output speed should be around 25 rpm under load.

Thank you so much for the response! Good to know the motor looks fine. The connection between the motor shaft and the weight is where I am having trouble. I cannot figure out how to lift 10 pounds a few inches using the motor "and" I cannot visualize how to lift horizontally using a motor/shaft mounted horizontally.

I am hoping to get some pointers that will help me answer your last 2 questions...just the words pulley, key screw, and gear box help though.

I just thought of this though after you said the word "pulley" - I am trying to fit this in a 25 " x 15" x 3" box. Maybe with these dimensions might be impossible? Here's a pdf of my super rough schematic. Thank you again for the response.

Thank you for the schematic.
Here is an idea:
