What is point contact and line contact?
Point contact is a sharp point contact and a line contact is spread over a larger plane. While gears can be easily conceptualized on a 2D plane, this is 3D we’re talking about so line contact would really translate to surface (face) contact and point contact to line contact (sharp edge over a length.
What is a gear drive?
Gear drives are packaged units used for a wide range of power-transmission applications. They are used to transmit power to a driven piece of machinery and to change or modify the power that is transmitted.
What is point of contact in gears?
Point contact or line contact is before the application of the load. Conventionally, elliptical or rectangular contact area is, after application of the load. Area kind corresponds the of engagement type. In this case there will be either point or line contact not surface contact.
What does a point of contact do?
A point of contact (POC), or a single point of contact, is an individual or a department that handles communication with customers. They serve as coordinators of information in terms of an activity or a project and act as an organization’s representatives.
What is the difference between a driving gear and a driven gear?
The gear that supplies the energy is called the DRIVING GEAR (often called the driver). The gear to which the force is directed is called the DRIVEN GEAR (often called the follower).
In which type of gearing the contact is point contact?
Screw Gear
Screw Gear Because the tooth contact is a point, their load carrying capacity is low and they are not suitable for large power transmission.
Which type of gears have a point contact between two mating gears?
Answer: There is a point of contact between two gears where as there is a line contact in a helical gear. Because of point of contact which changes during action, there is considerable sliding between the teeth. Efficiency of spiral gear is very low.
What is point of contact example?
When someone walks through the door of an outlet, the person who answers his queries acts as a point of contact for him.

Which gear goes the fastest?
Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that first gear is for speeds up to 10 mph, second gear is for speeds up to 15 mph, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear …
What is a girth gear?
Girth gears are used to drive large, rotating systems such as dryers, rotary kilns or horizontal mills.
Where does the line of contact begin and end?
The line of contact begins at the intersection A between the line of action and the addendum circle of the driven gear and ends at the intersection E between the line of action and the addendum circle of the driving gear. The so-called pressure angle α b refers to the angle between the normal of the line of centers and the line of action .
What is meant by Arc of contact in gear teeth?
Gear tooth are generally have cycloidal or involute profile. The curved traced by the point of contact of two teeth form beginning to the end of engagement is known as path of contact. It is the curve traced by the pitch point form the beginning to the end of engagement is known as arc of contact.
What is drive gear and drive gear?
The gear transmitting the force or motion is called the drive gear and the gear connected to the drive gear is called the driven gear. Gears are Used to Control Power Transmission in These Ways 1. Changing the direction through which power is transmitted (i.e. parallel, right angles, rotating, linear etc.) 2.
Why does the intersection of two involute gears describe a straight line?
Due to the special design of the tooth shape of an involute gear (rolling a straight line on a circle), the intersection of two involutes rolling off each other describes a straight line. This situation occurs when two gears are meshing.
