Creating the Gears
You can now create all the construction frames to locate each gear. For each gear, you will create one construction frame on each shaft. You use these construction frames to create gear pairs. Then you create a general part for each gear. You create gears with a fixed diameter (for example, 30 mm). Adams Driveline automatically parameterizes this diameter when you create the gear pairs.
To create the construction frames:
1. Create the first construction frame for the input shaft:
■Construction Frame: input_gear1
■Type: single
■Location Dependency: Delta location from coordinate
■Coordinate Reference: cfs_input_shaft
■Location: 0, 0, 20
■Location in: local
■Orientation Dependency: Delta orientation from coordinate
■Construction Frame: cfs_input_shaft
■Orientation: 0, 0, 0
2. Select Apply.
3. Create more construction frames for the input shaft using the same specifications used for the first construction frame, except for:
Construction Frame: | Location: |
|---|
input_gear2 | 0, 0, 40 |
input_gear3 | 0, 0, 80 |
input_gear4 | 0, 0, 130 |
input_gear5 | 0, 0, 170 |
4. Create the first construction frame for the output shaft using the same specifications used for the last construction frame, except for:
■Construction Frame: output_gear1
■Coordinate Reference: cfs_output_shaft
■Location: 0, 0, 20
■Construction Frame: cfs_output_shaft
5. Select Apply.
6. Create more construction frames for the output shaft using the same specifications used for the construction frame you created in Step 4, except for:
Construction Frame: | Location: |
|---|
output_gear2 | 0, 0, 40 |
output_gear3 | 0, 0, 80 |
output_gear4 | 0, 0, 130 |
output_gear5 | 0, 0, 170 |
To create a general part for each gear:
1. Use the General Part Wizard to create a general part for the first input gear:
■General Part Name: input_gear1
■Type: single
■Geometry Type: Gear
■Construction Frame: cfs_input_gear1
■Method: by entering size
■Top Radius: 30
■Pitch Radius: 30
■Length: 5
■Shaft: scaled off link
■Link: gralin_input_shaft
■Color: red
2. Select Apply.
3. Create general parts for all the other input gears, using the same specifications used for the first input gear, except for:
General Part Name: | Construction Frame: | Color: |
|---|
input_gear2 | cfs_input_gear2 | green |
input_gear3 | cfs_input_gear3 | magenta |
input_gear4 | cfs_input_gear4 | cyan |
input_gear5 | cfs_input_gear5 | skyblue |
4. Create a general part for the first output gear using the same specifications used for the last input gear, except for:
■General Part Name: output_gear1
■Construction Frame: cfs_output_gear1
■Link: gralin_output_shaft
■Color: red
5. Select Apply.
6. Create general parts all the other output gears, using the same specifications used for the first output gear, except for:
General Part Name: | Construction Frame: | Color: |
|---|
output_gear2 | cfs_output_gear2 | green |
output_gear3 | cfs_output_gear3 | magenta |
output_gear4 | cfs_output_gear4 | cyan |
output_gear5 | cfs_output_gear5 | skyblue |
To create the gear pairs:
1. From the Driveline Components menu, point to Gear Pair, and then select New.
2. Create the first gear pair:
■Gear Pair Name: gear1
■Input Shaft: ges_input_shaft
■Output Shaft: ges_output_shaft
■Input Reference Frame: cfs_input_gear1
■Output Reference Frame: cfs_output_gear1
■Gear Number: 1
■Configuration: Input Gear to Shaft
■Backlash: 0.0 deg
■Contact Stiffness: 1e7
■Contact Damping: 1e3
■Sharpness Factor: 1e4
■Invert output direction from input direction: selected
■Reduction Ratio Method: explicit
■Ratio: 4
■Input Gear: gragea_input_gear1
■Output Gear: gragea_output_gear1
3. Select Apply.
4. To create the rest of the gear pairs, repeat Steps 2 and 3, using the same specifications used for the first gear pair, except for:
Gear Pair Name: | Input Reference Frame: | Output Reference Frame: | Gear Number: | Ratio: | Input Gear: | Output Gear: |
|---|
gear2 | cfs_input_gear2 | cfs_output_gear2 | 2 | 3.5 | gragea_input_gear2 | gragea_output_gear2 |
gear3 | cfs_input_gear3 | cfs_output_gear3 | 3 | 2.2 | gragea_input_gear3 | gragea_output_gear3 |
gear4 | cfs_input_gear4 | cfs_output_gear4 | 4 | 1 | gragea_input_gear4 | gragea_output_gear4 |
gear5 | cfs_input_gear5 | cfs_output_gear5 | 5 | 0.8 | gragea_input_gear5 | gragea_output_gear5 |
