How to Draw in a Different Plane Solidworks
Welcome to SolidWorks tutorials for beginners and in this Solidworks exercises, you are going to acquire to brand gear 3D model. Information technology contains the both video and step past step pictorial explanations for creating different types of gear (Spur gear, helical gear bevel gear etc) in the graphics area of this CAD software. By doing this exercise, y'all will larn Solidworks features application like Extrude Boss, Extrude cut, Straight line, Eye line, Axis and Round Pattern. You will see how to utilise Solidworks features and sketch tools in simple style to create Spur gear 3D model. Also see How to make Spring 3D Model
Before going to this solidworks tutorial, you should accept some noesis about the gear, its types and major uses in engineering. Checkout All-time SolidWorks Training Materials here.
What is Gear (Mechanical Gear)?
Gear or Gears are toothed wheels which helps to transmit power and motion of i shaft to some other past means of engagement of its teeth. The power transmission is very constructive which gives positive bulldoze and accept constant velocity ratio. Gear box is very meaty in structure due the relatively small distance between drive and driven shaft.
Annotation: Drive shaft means which is directly connected to bulldoze machine (due east.thousand. motor) and driven shaft ways the rotation acquired due to motion of drive shaft (It is drive by drive shaft).
Gears are well capable to huge amount of power transmission every bit compared to chain and belt drives. You tin attain speed reduction even in small range which is cannot achieves by using concatenation or chugalug drives. These are the some of advantages of gears.
The bang-up disadvantages is that requires practiced lubrication and make clean working atmosphere due to date of teeth's. Construction is very compact considering of that manufacturing cost is also high. It also needs perfect alignment of shafts to provide efficient power transmitting capability with less loss and vibration.

Major uses of gears are:-
- In machine, used as Gear box to change the output shaft rotational speed with respect to input shaft speed.
- In Heavy lifting equipment (due east.g. crane), motor is couple to speed reduction gear to gethigh torque of heavy weight lifting
- Process industries, mechanical agitators, mixers, conveyor chugalug drive etc need speed reduction gear box
- In Marine application, Primary engine is turned with turning gear arrangement (pinion and gear blazon flywheel), Diesel fuel engines cranking arrangement contains speed reduction gear box
- In chain pulley
- Purifier drive mechanism( worm gear)
- Lathe, drilling, Milling, Grinding and other car tool applications
Types of Gears
Spur Gear:-
Teeth of spur gear is cutting parallel to the centrality of the shaft and and so it is as well called straight toothed gear. Because of the teeth alignment, yous tin use only when the drive and driven shafts are parallel. If you draw the profile of spur gear, it looks like an anfractuous curve.
Helical Gear:-
In helical gear, the teeth is cut an angle to shaft axis and profile is involute which is similar to spur gear. Hleix angle of both drive and driven gears should be aforementioned and one of should be right hand and other in left hand direction.
Bevel Gear:-
Bevel gear is seem like truncated cone, where the gear molar size and thickness decreasing towards the apex of the cone. Information technology enables the power manual in ninety degree where shaft centrality are intersecting. Bevel gear have 2 types of tooth cut which are either straight or spiral cut.
Worm Gear:-
Worm gear is different from other gear which consists of a worm and wheel. It enables 90 caste power transmission, where shafts axis are not intersecting. Worm is but like threaded screw which engages with molar of worm cycle. Main specialty of this gear is high speed reduction ration as compared to other gear types. Read more in wikipedia

How to Make Spur Gear 3D in SolidWorks Exercises
Pace-1: New Part File
Open up the SolidWorks and New part File. If you don't know it, read how to create new office File. Select the Plane (east.g. Top Airplane) and normalize using the "Normal To" Button.
Step-2: Create Circle Sketch
Go to the Sketch Control manager and select the "Circumvolve tool" from it. You tin select it from the Tools menu also.
This is the dedendum circumvolve of gear. And you have to give dimension equally per your requirement using Smart Dimension tool. Here, information technology is completely dimensions are selected roughly and only for solidworks tutorial purposes.
Stride-3: Use Extrude Boss/Base feature
To make dedendum circle as solid part, you accept to utilize extrude boss/base characteristic tool to circumvolve sketch.
Stride-4: Draw Gear Tooth Shape
Select 1 confront of extruded solid cylinder model and utilise "NormalTo" option from the heads-up toolbar. Yous tin apply it by clicking correct mouse button and select the NormalTo from information technology.
You accept to depict centerline using the Center line sketching tool.
Then depict gear tooth shape using the Line sketching tool which is shown as in the effigy.
It should make it as closed loop for awarding of SolidWorks feature tools.
Step-five: Apply Extrude boss
To catechumen tooth shape sketch to solid gear 3D tooth, apply extrude boss/base of operations feature on it.
Footstep-6: Utilise Circular Pattern
Earlier applying circular blueprint, you accept to make an axis for drive it. For that become to "reference plane" and select "Centrality" from it.
Axis property manager will appear and select "cylindrical/conical face" choice and select the aforementioned in "selections" section which shown in the figure. And click OK.
Then go to Features command manager and select "circular blueprint" from the driblet downward menu of linear pattern.
In the round pattern property manager, select the "parameters" equally similar bear witness in the figure.
Click OK to consummate spur gear 3D model.
If you want to make shaft hole in the spur gear 3D, draw a circle any one side of the gear.
Utilize extrude cutting option from the features command director. Final spur gear is look like the figure below.
