What is Curvic grind?

Curvic Grinding is among the most challenging grinding applications performed at Metalex, with the precision fit of each curvic interface being essential to the successful function of critical assemblies for highly engineered and demanding applications.

What is a Hirth?

A Hirth joint or Hirth coupling is a type of mechanical connection named after its developer Albert Hirth. It is used to connect two pieces of a shaft together and is characterized by tapered teeth that mesh together on the end faces of each half shaft.

What are the types of coupling?

Types of Couplings

• Rigid coupling.
• Flexible coupling.
• Sleeve or muff coupling.
• Split muff coupling.
• Flange coupling.
• Gear coupling.
• Universal joint (Hooke’s joint)
• Oldham coupling.

What are the two main types of coupling?

Following are the different types of coupling:

• Rigid Coupling.
• Sleeve or muff coupling.
• Clamp or split-muff or compression coupling, and.
• Flange coupling.
• Flexible coupling.
• Bushed pin-type coupling,
• Universal coupling, and.
• Oldham coupling.

What are the three types of coupling methods?

The different types of coupling are: Common-mode impedance (galvanic) coupling. Capacitive coupling. Inductive coupling.

What are the classification of coupling?

However there are two main types of couplings (Fig 1) which are (i) rigid couplings, and (ii) flexible couplings. Rigid couplings are used for shafts having no misalignment.

What are the different types of coupling?

What are different methods of coupling?

To connect analogue circuits together there are three basic methods, Direct Coupling, Capacitive Coupling and transformer coupling. All have different properties and can be used in any linear or non-linear circuit. With direct coupling, or DC coupling, two components are connected directly to each other.

What is the difference between oscillator and amplifier?

The main difference between an amplifier and oscillator is that amplifier is a circuit that amplifies the input signal and an oscillator generates AC waveforms of a particular frequency that acts as a source for an electronic circuit.

What is the principle of oscillator?

There are many types of electronic oscillators, but they all operate according to the same basic principle: an oscillator always employs a sensitive amplifier whose output is fed back to the input in phase. Thus, the signal regenerates and sustains itself. This is known as positive feedback.

How are Curvic couplings made?

Figure 1 : Typical curvic coupling Curvic couplings are produced by plunging a cup shaped grinding wheel towards the blank material, i.e. the wheel is moved along its axis of rotation, parallel to the curvic axis.

How to evaluate the stiffness weakening caused by Curvic couplings?

The stiffness weakening caused by the connection of curvic couplings is evaluated by the ratio of the stiffness difference between curvic couplings and continuous structures to the stiffness of continuous structures with the same size. The results are shown in Table 4.

Where are the teeth located in a curvic coupling?

In a typical curvic coupling of a shaft, the teeth are generally located at the end faces of annular shafts, showing a hub-and-spoke pattern, as shown in Figure 1 (a). The shape of tooth surfaces is part of a cone, and the cross section of a tooth along the radius of the shaft is trapezoidal.

How are the teeth of a joint coupling cut?

After each cut the curvic blank is rotated through the pitch angle of the teeth and another pair of faces is cut. In some couplings a slot is machined in the middle of the teeth in order to allow the joint coupling bolts to apply the clamping force through the centre of the teeth.
