Explanation:
In the case of an involute toothed gear, the involute starts from the base circle. The base circle is an imaginary circle that is tangent to the profile of the gear tooth at the point where the involute curve starts.
Understanding Gear Tooth Profiles:
To understand why the involute starts from the base circle, let's first understand the concept of gear tooth profiles. In involute gears, the shape of the tooth profile is crucial for proper functioning and smooth meshing of gears.
The gear tooth profile is defined by two curves - the involute curve and the fillet curve. The involute curve is a specific mathematical curve that is used to define the shape of the gear tooth. It is a curve traced by a point on a taut string as it unwinds from the base circle.
Base Circle:
The base circle is an imaginary circle that is used as a reference for generating the involute curve. It is defined by the radius of the base circle, which is directly related to the module or diametral pitch of the gear.
The involute curve starts from the point where the base circle and the pitch circle intersect. This point is called the base point. The involute is then generated by unwinding a string from the base point while keeping it tangent to the base circle.
Role of the Base Circle:
The base circle plays a crucial role in determining the shape and size of the gear tooth profile. It defines the starting point of the involute curve and ensures that the gear teeth mesh properly.
The involute curve is designed to have certain properties that make it ideal for gear tooth profiles. It provides a smooth and gradual transition of contact between the gear teeth, resulting in less wear and noise during operation.
Conclusion:
In conclusion, the involute starts from the base circle in the case of an involute toothed gear. The base circle is an imaginary circle that is tangent to the profile of the gear tooth at the point where the involute curve starts. The involute curve is generated by unwinding a string from the base point while keeping it tangent to the base circle. The base circle plays a crucial role in determining the shape and size of the gear tooth profile, ensuring proper meshing and smooth operation of the gears.
