Abstract
A method of forming a flapper assembly (200) for a throttle valve (100) is provided. The method includes steps of forming a flapper (110) comprised of hub (112) having an opening (114) and at least one vane (116a,b) coupled to the hub (112), disposing a shaft (210) in the opening (114), and pressing a punch (P) into an outer surface (112a) of the hub (112) such that a torque dimple (118) extends from the hub (112) into the shaft (210) to fasten the flapper (110) to the shaft (210).

A method of forming a flapper assembly (200) for a throttle valve (100), the method comprising steps of:
- forming a flapper (110) comprised of hub (112) having an opening (114) and at least one vane (116a,b) coupled to the hub (112);
- disposing a shaft (210) in the opening (114);
- and
- pressing a punch (P) into an outer surface (112a) of the hub (112) after the shaft (210) is disposed in the opening (114) such that a torque dimple (118) extends from the hub (112) into the shaft (210) to fasten the flapper (110) to the shaft (210).
A flapper assembly (200) for a throttle valve (100) comprised of:
- a flapper (110) comprised of hub (112) having an opening (114) and at least one vane (116a,b) coupled to the hub (112);
- a shaft (210) disposed in the opening (114);
- and
- at least one torque dimple (118) in the hub (112) that extends into the shaft (210) to fasten the flapper (110) to the shaft (210), said at least one torque dimple (118) being pressed by a punch (P) after the shaft (210) is disposed in the opening (114).
A method of forming a throttle valve (100), the method comprising
- forming a flapper (110) comprised of hub (112) having an opening (114) and at least one vane (116) coupled to the hub (112);
- forming and adapting a housing (120) with an aperture (122) to channel a flow stream through the housing (110);
- forming and disposing a shaft (210) in the opening (114) of the flapper (110) and coupling the shaft (210) to the housing (120) such that the flapper (110) is disposed in the aperture (122) to regulate the flow stream through the housing (110);
- and
- pressing a punch (P) into an outer surface (112a) of the hub (112) after the shaft (210) is disposed in the opening (114) such that a torque dimple (118) extends from the hub (112) into the shaft (210) to fasten the flapper (110) to the shaft (210).
