How To Make Gears In Onshape?

How to Make Gears in Onshape

Gears are an essential component of many mechanical systems, and they can be used to transmit power from one shaft to another. In this tutorial, we will show you how to create gears in Onshape, a cloud-based CAD platform. We will cover the basics of gear design, and we will walk you through the steps of creating a gear model in Onshape. By the end of this tutorial, you will be able to create your own custom gears for use in your own designs.

What are Gears?

Gears are a type of mechanical linkage that uses the principles of circular motion to transmit power from one shaft to another. Gears are made up of two or more toothed wheels that mesh together, and when one wheel rotates, it causes the other wheel to rotate as well. The ratio of the number of teeth on each wheel determines the gear ratio, which is the amount of speed and torque that is transferred from one shaft to the other.

Why Use Gears?

Gears are used in a wide variety of applications, including:

• Power transmission: Gears are used to transmit power from one shaft to another, and they can be used to increase or decrease the speed or torque of the output shaft.
• Speed reduction: Gears can be used to reduce the speed of a rotating shaft, which is often necessary for applications such as conveyor belts and machine tools.
• Torque multiplication: Gears can be used to multiply the torque of a rotating shaft, which is often necessary for applications such as electric motors and power steering systems.

How to Create Gears in Onshape

Creating gears in Onshape is a relatively simple process, and it can be done using the following steps:

1. Create a new part file.
2. Add a sketch to the part file.
3. Draw the outline of the gear teeth.
4. Extrude the gear teeth.
5. Add fillets to the gear teeth.
6. Add chamfers to the gear teeth.
7. Add a material to the gear.
8. Save the part file.

Once you have created your gear model, you can export it to a 3D printing file or use it in another CAD or CAM software.

How To Make Gears In Onshape?

Onshape is a cloud-based CAD platform that allows you to create and edit 3D models. It is a powerful tool that can be used to create a variety of different types of parts, including gears. In this tutorial, we will show you how to create gears in Onshape.

1. Designing Gears in Onshape

To create a gear in Onshape, you will need to first create a new part. To do this, click on the “New” button in the top left corner of the screen and select “Part.”

Once you have created a new part, you will need to add a sketch. To do this, click on the “Sketch” button in the toolbar and select “XY Plane.”

Now you can start drawing your gear. The first thing you need to do is draw the outline of the gear. To do this, use the “Line” tool to draw a circle. The radius of the circle will determine the size of the gear.

Once you have drawn the outline of the gear, you need to add the teeth. To do this, use the “Gear” tool. The “Gear” tool allows you to specify the number of teeth, the pressure angle, and the diametral pitch of the gear.

After you have added the teeth, you need to generate the gear features. To do this, click on the “Features” tab and select “Gear.” The “Gear” feature will create the gear teeth and the gear hub.

2. Editing Gears in Onshape

Once you have created a gear, you may need to edit it. To do this, you can use the following tools:

• “Change Gear Parameters” tool: This tool allows you to change the number of teeth, the pressure angle, and the diametral pitch of the gear.
• “Add Fillet” tool: This tool allows you to add fillets to the edges of the gear.
• “Add Chamfer” tool: This tool allows you to add chamfers to the edges of the gear.
• “Apply Material” tool: This tool allows you to apply a material to the gear.
• “Apply Finish” tool: This tool allows you to apply a finish to the gear.

In this tutorial, we showed you how to create and edit gears in Onshape. We hope that you found this tutorial helpful. For more information, please refer to the Onshape documentation.

3. Simulating Gears in Onshape

Once you have created your gears in Onshape, you can simulate their operation to ensure that they will perform as expected. This can be done using the gear mesh simulation tool.

To run a gear mesh simulation, follow these steps:

1. Select the gears that you want to simulate.
2. Click the Simulate tab.
3. Click the Gear Mesh button.

The gear mesh simulation dialog box will appear. This dialog box allows you to specify the following parameters:

• The number of teeth on each gear
• The module of the gears
• The pressure angle of the gears
• The lubricant used between the gears
• The rotational speed of the gears

Once you have specified the desired parameters, click the Run button to start the simulation. The simulation results will be displayed in the Results tab.

The simulation results will show the following information:

• The contact forces between the gears
• The gear mesh efficiency
• The power transmitted by the gears

You can use the simulation results to identify any potential problems with your gear design. For example, you can check to make sure that the contact forces are within the allowable limits and that the gear mesh efficiency is high.

Analyzing the Simulation Results

The simulation results can be used to analyze the performance of your gear design. You can use the following steps to analyze the simulation results:

1. Check the contact forces to make sure that they are within the allowable limits.
2. Check the gear mesh efficiency to make sure that it is high.
3. Check the power transmitted by the gears to make sure that it is sufficient for the application.

If any of the simulation results are not within the desired limits, you may need to modify your gear design and run the simulation again.

4. Exporting Gears from Onshape

Once you have created your gears in Onshape, you can export them to a CAD file format or a 3D printing file format. This allows you to share your gear design with others or to use it to create a physical prototype.

Exporting to a CAD File Format

To export your gears to a CAD file format, follow these steps:

1. Select the gears that you want to export.
2. Click the File menu.
3. Click the Export button.
4. Select the desired CAD file format.
5. Click the Export button.

The CAD file will be saved to the specified location.

Exporting to a 3D Printing File Format

To export your gears to a 3D printing file format, follow these steps:

1. Select the gears that you want to export.
2. Click the File menu.
3. Click the Export button.
4. Select the desired 3D printing file format.
5. Click the Export button.

The 3D printing file will be saved to the specified location.

You can then use the 3D printing file to create a physical prototype of your gear design.

In this tutorial, you learned how to create, simulate, and export gears in Onshape. You can use these skills to create gear designs that meet your specific requirements.

How do I create a gear train in Onshape?

To create a gear train in Onshape, follow these steps:

1. Create the gears that will be in the gear train.
2. Align the gears so that their pitch circles are concentric.
3. Connect the gears with shafts.

What are the different types of gears?

There are four main types of gears:

• Spur gears: Spur gears are the simplest type of gear. They have straight teeth that are aligned with the axis of rotation.
• Helical gears: Helical gears have teeth that are inclined to the axis of rotation. This reduces friction and noise.
• Bevel gears: Bevel gears have teeth that are angled to each other. They are used to connect shafts that are at an angle to each other.
• Worm gears: Worm gears have a worm gear and a worm wheel. The worm gear is a screw-shaped gear, and the worm wheel is a gear with teeth that are angled to the axis of the worm gear. Worm gears are used to create a high gear ratio.

What are the advantages and disadvantages of gears?

The advantages of gears include:

• High efficiency: Gears can transmit power with very little loss of efficiency.
• Wide range of gear ratios: Gears can be used to create a wide range of gear ratios.
• Compact design: Gears can be used to create compact mechanisms.

The disadvantages of gears include:

• Noise: Gears can create noise when they are in operation.
• Friction: Gears can create friction, which can reduce efficiency.
• Cost: Gears can be expensive to manufacture.
