There will be a minimum of 28 teeth in the annular gear that can gear with the 18-tooth pinion.

Given that the gears are Cycloidal gears; interchangeable set; 3 diametral pitch; radial flanks on a 15-tooth gear. Addendum equals 1 in. ÷ diametral pitch.

Clearance equals one-eighth of the addendum.

An 18-tooth pinion drives a 39-tooth annular. We are required to find the path of contact.

Path of contact in Cycloidal gears is a curve generated by a point on a circle rolling along a straight line.

The path of contact is represented by an arc of the pitch circle of each gear.

Cycloidal gears are a type of gear where the teeth have a rounded shape, in contrast to involute gears, which have a tooth profile that is involute in shape.

The rounded teeth allow for smoother engagement and less noise.

The addendum equals 1 in. ÷ diametral pitch, the clearance equals one-eighth of the addendum.

The diametral pitch is given to be 3.

Therefore, the addendum of the gear = 1/3 in

The clearance of the gear = 1/8 * (1/3) = 1/24 in

The base circle diameter = pitch circle diameter - 2 × (1/3) = 5/3 in.

The radius of the base circle = 5/6 in.

The radius of the addendum circle = 5/6 + 1/3 = 7/6 in.

The radius of the dedendum circle = 5/6 - 1/24 = 19/24 in.

The pitch circle diameter of the 15-tooth gear = 15/3 in = 5 in.

Now, to find the path of contact, we need to determine the value of the backlash.

Backlash is the amount by which the width of a tooth space exceeds the thickness of the engaging tooth.

The recommended value of backlash for a cycloidal gear drive is 1% to 2% of the module.

For Cycloidal gears, the recommended backlash is 0.25 x modulus of the gear.

To find the minimum annular tooth that will gear with the 18-tooth pinion, we need to use the formula:

(N1 + N2)/P = (P1 + P2)/P = k,

where P = Diametral Pitch

k = 2 for Cycloidal gears,

N1 and N2 are the number of teeth on the gears 1 and 2 respectively,

and P1 and P2 are their respective pitch circles.

Substituting the values:N1 = 18, N2 = 39P = 3k = 2

Diameter of the pitch circle of the pinion = 18/3 in = 6 in

Diameter of the pitch circle of the annular = 39/3 in = 13 in

Using the formula above:(18 + N2)/6 = (13 + N2)/13

Solving the above equation gives us the value of N2 as 28 teeth.

The path of contact for the above problem is shown in the attached image.

Therefore, there will be a minimum of 28 teeth in the annular gear that can gear with the 18-tooth pinion.

The base circle diameter of the smallest annular gear is calculated as, BD' = PD' - 2a' = 0.9 - 2/20 = 0.8 in

Given that 15-tooth gear has an addendum of 1 in/DP and clearance equals one-eighth of the addendum,

Addendum,

a = 1 in/DP => 1/3 in

Clearance, c = 1/8 * 1/DP => 1/24 in

Therefore, the outside diameter of the 15-tooth gear would be,

OD = PD + 2a = 15/3 + 2(1/3) = 7 in

Also, the pitch diameter of the gear is given as,

PD = N/DP = 15/3 = 5 in.

Now, the base circle diameter of the gear is calculated as,

BD = PD - 2a = 5 - 2/3 = 13/3 in

The path of contact between the mating gears is cycloidal in nature.

It is shown as follows:

Given that 18-tooth pinion drives a 39-tooth annular,

The diametral pitch, DP = 3

For minimum number of teeth, DP should be maximum, say DP' = 20For DP' = 20,

Number of teeth, N = PD' * DP' = 360/20 = 18

Now, the outside diameter of the smallest annular gear would be,

OD = PD' + 2a' = 18/20 + 2(1/20) = 0.95 in

Also, the pitch diameter of the gear is given as,

PD' = N/DP' = 18/20 = 0.9 in.

The base circle diameter of the smallest annular gear is calculated as,

BD' = PD' - 2a' = 0.9 - 2/20 = 0.8 in

The path of contact between the mating gears is shown below:

The amalgam type which tends not to displace the matrix band in class II restorations, requiring a larger wedge to separate the teeth more for good proximal contact is Lathe-cut.

What is amalgam?Amalgam is a dental filling material that has been used for over 150 years to restore decayed teeth. It is made up of a mixture of metals, including silver, tin, copper, and mercury. When these metals are mixed together, they form a soft, pliable material that can be packed into a cavity in a tooth. Over time, the amalgam hardens and becomes a strong, durable filling material.Amalgam restorations are one of the most common types of restorations used to repair cavities.

They are durable, long-lasting, and relatively inexpensive. However, there are some disadvantages to using amalgam as a filling material. One of these is that it can be difficult to get a good proximal contact with the adjacent tooth, especially in class II restorations.

The type of amalgam that tends not to displace the matrix band in class II restorations, requiring a larger wedge to separate the teeth more for good proximal contact is Lathe-cut. Lathe-cut amalgam is made by grinding a mixture of metals into a powder. This powder is then compressed into a solid block and sliced into pieces. Lathe-cut amalgam tends to be more brittle than other types of amalgam, which makes it less likely to deform and displace the matrix band.
