In which of these the two gears are mounted on the same shaft?

Compound gear train: When any shaft have more than one gear (first shaft or second shaft or intermediate shaft) i.e. two gear have same angular velocity, the gear drive is called compound gear drive.

What is a driving sprocket?

1. Any of various toothlike projections arranged on a wheel rim to engage the links of a chain. 2. A cylinder with a toothed rim that engages in the perforations of photographic or movie film to pull it through a camera or projector.

Is torque constant along a shaft?

Torque — also called MOMENT OF A FORCE, in physics, the tendency of a force to rotate the body to which it is applied. a) Torque stays constant along a shaft (so we’re neglecting any friction in bearings that hold the shaft in place).

When there is only one gear on each shaft it is known as?

When there is only one gear on each shaft, as shown in Fig., it is known as simple gear train. The gears are represented by their pitch circles. When the distance between the two shafts is small, the two gears 1 and 2 are made to mesh with each other to transmit motion from one shaft to the other, as shown in Fig.

Do gears on the same shaft have the same angular velocity?

Yes, they will rotate at the same speed and are called compound gears. The gears that make up a compound gear usually differ in size and have a different number of teeth.

How many types of sprockets are there?

There are four main types of sprockets as established by the American National Standards Institute (ANSI): Type A sprockets, which are only the plate with no added thickness or hubs. Type B sprockets, which have a hub on one side. Type C sprockets, which have hubs of equal thickness on both sides of the plate.

Where are sprockets used?

Sprockets are used in bicycles, motorcycles, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc.

Do gears move at the same speed?

A gear is a simple mechanical device that transmits rotational motion (force) to another gear or device. Thus, the larger a gear’s radius, the slower its rotational speed. Gear Ratios. When the teeth of two gears interlock, the gears themselves move at the same speed (meters per second or feet per minute).

What is torque in a shaft?

WHAT IS TORQUE? Shaft torque is measured by a device that records the amount a shaft will twist under a certain amount of force, and it’s recorded in degrees. A shaft with 3 degrees of torque will twist less than a shaft with 5 degrees of torque, and so on.

How is shaft torque calculated?

For motors, find torque (in ft-lb) using this equation: T = (HP*5252)/rpm.

How are the sprockets secured to the shaft?

Typically, the sprockets are secured to the shaft using an ANSI standard dimensioned keyway and one or more set screws. The ANSI standards provide a keyway of specific length, width and depth for a given shaft diameter. See Fig. 6 for a partial listing of common keyway dimensions. It is possible that your application not match this standard.

What is the difference between a sprocket and a gear?

Unlike gears—which interlock together to transfer rotational movement— sprockets only directly interact with different types of chains. Rather than a gear system, most sprocket and chain systems work in a similar manner to bicycle chain assemblies—which is itself a lightweight sprocket and chain assembly.

What is the bore size of a single sprocket?

The sprocket halves are held together by bolts on either side of the hub. This particular style is normally available in chain pitch sizes of 40 through 240, and bore diameters of 3/4” through 6”, depending on chain pitch selected. Double single sprockets: This type of sprocket (Fig.

How does a drive shaft transmit power?

Shafts transmit power directly from a driving device or power source into a load (figure 1). Shafts can carry gears, pulleys, and sprockets in order to transmit rotary motion and power via mating gears, belts, and chains. Alternatively, a shaft may simply connect to another shaft via a coupling mechanism.
