Helical gears have teeth that are oriented at an angle to the shaft, unlike spur gears which are parallel.ħ. Spur gears transmit power through shafts that are parallel.Ģ. If the shaft was not created by the shaft generator. In the drawing area, select the objects that form the shaft to analyze.ĥ. At the command prompt, enter C (for create).ģ.
Click Content tab Calculation panel drop-down Shaft Calculation. Some of GearTeqs enhanced features: Face gears, axis coincident and at 90 degrees. GearTeq can also be run as a standalone program. Available for SOLIDWORKS, Solid Edge and Inventor. Step 4: Use Circular Pattern to Finish the Sprocket.ĥ. GearTeq provides the designer with advanced tools for creating solid models of drive components and assemblies. Step 1: Get DraftSight or Other 2D CAD.Ģ. If the sprocket gear is created outside of the active body, drag and drop it into a body for the application of further features like padding.
Set the DataNumber Of Teeth and the DataSprocket Reference.Ĥ. It changes the rotational movement by 90 degrees, and the plane of movement also changes due to the position of the worm on the worm wheel (or simply “the wheel”). How do you identify a worm gear?īasically, a worm gear is a screw butted up against what looks like a standard spur gear with slightly angled and curved teeth. Worm Gear Screw Jacks Design Versions Rotating screw - version R Driven by a precision worm gearing (worm shaft and worm wheel), the rotary motion of the screw is translated into linear motion of the travelling nut on the screw. Typical pressure angles are 14.5° or 20°. Pressure angle is the angle of tooth drive action, or the angle between the line of force between meshing teeth and the tangent to the pitch circle at the point of mesh. In a worm drive, it is called axial pitch and can be measured by the formula CP= Π ÷ DP.

Step 4: Measure the centre of the driven gear from the centre of the driver gear. Step 3: Calculate the pitch centre distance.Ĥ. Step 2: Draw a vertical centre line for the driver gear on the left.ģ. Step 1: Start by drawing a horizontal centre line for both gears.Ģ.
