Hi Reverse Engineer Your Conveyor.

Timing, Timing, Timing!

Efficient manufacturing boils down to cohesiveness, and a major component of this is timing. When dealing with container handling solutions, that translates into timing screws.

With the ability to make or break production, it's important that you properly manage every aspect of your timing screws. 

In this case, knowing their functionality and terminology are a great starting point.

What are they?

Timing screws are perhaps one of the most critical aspects of a packaging line. 

Without them, your line is pretty much useless. 

The major function they have is to smoothly transfer containers between packaging machines.

They run on rotary equipment and are placed next to a star wheel so that they can accept, separate, accelerate, or discharge containers according to the machine's requirements.

Timing screws can be designed in many different shapes and patterns to accommodate the container they will be handling, but to make sure you're getting one that will work best for you, careful engineering and craftsmanship must be used to get it right.

Terminology;

There are a couple different terms that are useful to know when dealing with timing screws. That way when yours is getting designed, you know what elements the designer is referring to.

Pockets and Lands;

A pocket is basically the part that the container is nestled into when it's moved along the timing screw. 

This must be carefully measured and designed so that it fits the container precisely and properly.

The land is the part of the screw that protrudes out and holds the container in place on either side. 

As the screw spins, the land moves forward, holding and pushing the container with it. 

The land can vary in size and width depending on the container being handled and the function of the timing screw.

Lead Edge and Following Edge;

The lead edge is the edge of the land that is in front of the container, separating it from the container in front of it. 

The following edge is the edge behind the container that pushes it and keeps it nestled in the pocket (the area between the lead edge and following edge).

Discharge Pitch;

The discharge pitch is basically the distance from lead edge to lead edge-or from the front of one pocket to the front of the next pocket.

Root Diameter and Outside Diameter;

The root diameter is the diameter of the inside of the screw-the cylinder that the land protrudes from.

The outside diameter includes the land. 

So, this would be the measurement of the root diameter plus how far out the land protrudes on all sides.

Other Functions;

Although the main function of timing screws is to move containers along smoothly from one section to another, new designs and creative engineering has enabled them to do far more than just that.

For instance, timing screws can also be designed to accelerate or decelerate the movement of a container, divide containers, combine them, or even halt them momentarily, but these tasks are only possible if the screw is specially tailored to the shape of the container. 

So, as was said before, proper measurement and design is crucial.

1 - "What is a Thin Section Bearing and How Does it Reduce Cost?."

Thin section bearings are a family of bearings designed from a limited number of widths and thicknesses (cross sections), with each cross section manufactured in a wide range of bore diameters.

 Most radial ball bearings are designed so that as the bore size increases, the width and the thickness of the bearing change proportionately. In the case of thin section bearings the cross section remains the same as the bore diameter increases. 

The thin section bearing family is made up of 12 primary cross section sets ranging from 3/16" to 1" and with bore sizes ranging from 1" to over 40". 

The combination of a large bore diameter in proportion to the small cross section makes these parts appear "thin" in comparison to standard ball bearings. Thin section bearings are made from 52100 chrome steel and 440C stainless steel.

"Thin section bearings help reduce total cost in a system by allowing for design efficiency over standard bearing sizes."

 They can also be coated with platings like thin dense chrome. Some sizes can be configured with seals or shields. Thin section bearings are also made in one of three different contact styles; radial contact, angular contact, and four point contact. These options, along with several ball and retainer types make for a diverse range of parts even among the limited cross sections of the thin section bearing family.

Thin section bearings help reduce total cost in a system by allowing for design efficiency over standard bearing sizes. As thin section bearings have cross sections that don't change as bore sizes increase, there needs to be no change in the space requirements, and little change in the weight of the bearing, even as the diameter of an application increases. 

Especially in the case of medical equipment, airborne optical and infrared scanning equipment, and robotics, the space and weight requirements of a system are major factors in the overall design and manufacturing cost. 

In many cases, the price of a thin section bearing is higher than a standard bearing with a similar bore size, but application and design savings due to reduced space and lower weight decrease the total cost in the application.

2 - "Thin Section Bearings - Why are there 3 different types?"

Thin precision thin section bearings are used in numerous exotic and high tech applications. 

These Provide precision and performance in applications such as robotics, aerospace, machine tools, semiconductor manufacturing and medical equipment. Applications requiring thin profiles are ideal for thin section bearings. 

They are available in bore sizes from 1” to 36” with cross sections from 3/16 to 1”. Stainless steel and sealed versions are also available to meet specific application requirements. 

A Sample Of Thin bearings are manufactured in three different types for explanation purposes & understanding other manufacturers may wish a different format to their bearings & selection.

The C-Type - Is a “Radial Contact” type of conventional bearing design. It has a single row of balls which allows for Conrad-type assembly. 

The C-Type is most commonly used among the three thin section types. Although the radial type is used primarily in applications with radial loads, it can withstand moderate axial and reversing loads as well as moment loads.

The A-Type - Is an “Angular Contact” type bearing with a reduced shoulder on one side of the inner or outer race ball path. 

These bearings accept radial loads and single direction thrust loads. 

The A-Type requires an application of thrust to establish the appropriate race and ball contact angle. 

These bearings are commonly used in pairs for applications requiring axial loads in one direction or for reversing axial loads. 

They provide the appropriate stability, load capacity and repeatability needed in applications requiring higher speeds than the C-Type.

The X-Type - Is a “4-Point Contact” bearing used where a high level of rigidity is required. 

This bearing can accept radial and thrust loads in either direction. 

They are also extremely effective with high moment loads. 

X-Type bearings are designed with gothic raceways creating 4 contact points between each ball and the raceway. 

Preloading will provide for additional precision and rigidity of movement. 

X-Type bearings may be able to replace two thin section bearings in many applications.

Thin section bearings are specified in areas requiring design efficiency, high precision and minimal space. 

Creating space and saving weight are also two key considerations when selecting thin section bearings.

3 - "Don't forget to consider moment loads when specifying thin section bearings."

What is a moment load?A moment load is a tilting load that attempts to rotate the rings of a rolling element bearing in a rotational manner perpendicular to the designed rotational axis. 

Single ball bearings aren't usually designed to handle moment loads, but Silverthin offers engineered solutions for space and weight limited applications.

To further explain, a moment load may also be thought of as a "torque". 

A "moment", or "torque", is a force (or load) acting at a specified distance from a specified point.

 For example, when you tighten a bolt using a wrench, the resulting "moment" is the product of the amount of actual force you exert on the wrench multiplied by the distance from the center of the bolt to the position of your hand on the wrench. 

In the case of a bearing, a moment load is a multiple of the distance from the center of the bearing and the force acting on an arm.

Most designers are familiar with bearing applications having multiple bearings (2 or more) that work together to accommodate the loading in the system. 

The resulting bearing loads in these cases are typically analyzed as radial or thrust loads when evaluating the bearing system. 

However, by only having a single bearing, any radial load in a system acting anywhere other than at the center of the bearing ball path will generate a moment load. 

Some Thin manufacturers offer bearings from stock that are specifically designed for applications with significant moment loads, where there are space, weight and cost saving benefits of using a single bearing. 

These are unique and specially designed single row, thin-section ball bearings where the internal geometry of the race is reminiscent of a gothic arch, also known as an "X-Type" design.

When only one bearing is in a system, as is also the case in many slewing ring bearing applications, any load can generate significant moment load. 

Large moment loads often occur when an apparatus extends from a platform with a slewing ring or thin section bearing at its base.

 A simple example might be that of a robotic arm extending a few feet from a stationary base to pick a heavy object and turn it. 

The thin-section or slewing ring bearing at the base of the arm connecting it to the platform experiences a moment load.

When a bearing is constantly or intermittently loaded, it should be engineered to handle the life requirements of the application.

 It is important to identify as much of the potential loading that a bearing system could face at the design stage in order assure the complete system will meet its users' service requirements.
