4. SAFETY INSTRUCTION

Factor of safety	According to the European CE safety requirements for lifting equipment, and safety regulations on the German accident prevention regulations UVV 18 and VBG 9a, the best safety factor for vacuum lifter is 2.5. For example, each sucker 250mm dia., with suction CZPT to 250kgf, divided by the safety factor 2.5, can load 100kg. If the lifter uses 4 suction cups, the total suction is 100*4=400kg, greater than approved glass 250kg. When the glass is handled and transported vertically, it should be multiplied by the coefficient of friction 0.8 (between rubber and glass), 400kg*0.8=320kg, still greater than the approved glass 250kg.
Safety Protection Instruction	Once glass sucked, the system is under airtight state. The only entrance for air is backflow from vacuum generator to destroy system’s vacuum state. Therefore, the lifter is equipped with the safety non-return valve, for which air can only be extracted from inner system, with no return, and through which it can ensure sufficient vacuum to keep absorption time when power loss.
Vacuum Compensation Protection	Not worried about air leakage and insufficient vacuum, because the lifter is equipped with pressure sensor and vacuum compensation system. When vacuum is not enough, the system automatically senses and resumes operation to keep sufficient vacuum.

Lead Screws and Clamp Style Collars

If you have a lead screw, you’re probably interested in learning about the Acme thread on this type of shaft. You might also be interested in finding out about the Clamp style collars and Ball screw nut. But before you buy a new screw, make sure you understand what the terminology means. Here are some examples of screw shafts:

Acme thread

The standard ACME thread on a screw shaft is made of a metal that is resistant to corrosion and wear. It is used in a variety of applications. An Acme thread is available in a variety of sizes and styles. General purpose Acme threads are not designed to handle external radial loads and are supported by a shaft bearing and linear guide. Their design is intended to minimize the risk of flank wedging, which can cause friction forces and wear. The Centralizing Acme thread standard caters to applications without radial support and allows the thread to come into contact before its flanks are exposed to radial loads.
The ACME thread was first developed in 1894 for machine tools. While the acme lead screw is still the most popular screw in the US, European machines use the Trapezoidal Thread (Metric Acme). The acme thread is a stronger and more resilient alternative to square threads. It is also easier to cut than square threads and can be cut by using a single-point threading die.
Similarly to the internal threads, the metric versions of Acme are similar to their American counterparts. The only difference is that the metric threads are generally wider and are used more frequently in industrial settings. However, the metric-based screw threads are more common than their American counterparts worldwide. In addition, the Acme thread on screw shafts is used most often on external gears. But there is still a small minority of screw shafts that are made with a metric thread.
ACME screws provide a variety of advantages to users, including self-lubrication and reduced wear and tear. They are also ideal for vertical applications, where a reduced frictional force is required. In addition, ACME screws are highly resistant to back-drive and minimize the risk of backlash. Furthermore, they can be easily checked with readily available thread gauges. So, if you’re looking for a quality ACME screw for your next industrial project, look no further than ACME.

Lead screw coatings

The properties of lead screw materials affect their efficiency. These materials have high anti-corrosion, thermal resistance, and self-lubrication properties, which eliminates the need for lubrication. These coating materials include polytetrafluoroethylene (PFE), polyether ether ketone (PEK), and Vespel. Other desirable properties include high tensile strength, corrosion resistance, and rigidity.
The most common materials for lead screws are carbon steel, stainless steel, and aluminum. Lead screw coatings can be PTFE-based to withstand harsh environments and remove oil and grease. In addition to preventing corrosion, lead screw coatings improve the life of polymer parts. Lead screw assembly manufacturers offer a variety of customization options for their lead screw, including custom-molded nuts, thread forms, and nut bodies.
Lead screws are typically measured in rpm, or revolutions per minute. The PV curve represents the inverse relationship between contact surface pressure and sliding velocity. This value is affected by the material used in the construction of the screw, lubrication conditions, and end fixity. The critical speed of lead screws is determined by their length and minor diameter. End fixity refers to the support for the screw and affects its rigidity and critical speed.
The primary purpose of lead screws is to enable smooth movement. To achieve this, lead screws are usually preloaded with axial load, enabling consistent contact between a screw’s filets and nuts. Lead screws are often used in linear motion control systems and feature a large area of sliding contact between male and female threads. Lead screws can be manually operated or mortised and are available in a variety of sizes and materials. The materials used for lead screws include stainless steel and bronze, which are often protected by a PTFE type coating.
These screws are made of various materials, including stainless steel, bronze, and various plastics. They are also made to meet specific requirements for environmental conditions. In addition to lead screws, they can be made of stainless steel, aluminum, and carbon steel. Surface coatings can improve the screw’s corrosion resistance, while making it more wear resistant in tough environments. A screw that is coated with PTFE will maintain its anti-corrosion properties even in tough environments.

Clamp style collars

The screw shaft clamp style collar is a basic machine component, which is attached to the shaft via multiple screws. These collars act as mechanical stops, load bearing faces, or load transfer points. Their simple design makes them easy to install. This article will discuss the pros and cons of this style of collar. Let’s look at what you need to know before choosing a screw shaft clamp style collar. Here are some things to keep in mind.
Clamp-style shaft collars are a versatile mounting option for shafts. They have a recessed screw that fully engages the thread for secure locking. Screw shaft clamp collars come in different styles and can be used in both drive and power transmission applications. Listed below are the main differences between these 2 styles of collars. They are compatible with all types of shafts and are able to handle axial loads of up to 5500 pounds.
Clamp-style shaft collars are designed to prevent the screw from accidentally damaging the shaft when tightened. They can be tightened with a set screw to counteract the initial clamping force and prevent the shaft from coming loose. However, when tightening the screw, you should use a torque wrench. Using a set screw to tighten a screw shaft collar can cause it to warp and reduce the surface area that contacts the shaft.
Another key advantage to Clamp-style shaft collars is that they are easy to install. Clamp-style collars are available in one-piece and two-piece designs. These collars lock around the shaft and are easy to remove and install. They are ideal for virtually any shaft and can be installed without removing any components. This type of collar is also recommended for those who work on machines with sensitive components. However, be aware that the higher the OD, the more difficult it is to install and remove the collar.
Screw shaft clamp style collars are usually one-piece. A two-piece collar is easier to install than a one-piece one. The two-piece collars provide a more effective clamping force, as they use the full seating torque. Two-piece collars have the added benefit of being easy to install because they require no tools to install. You can disassemble one-piece collars before installing a two-piece collar.

Ball screw nut

The proper installation of a ball screw nut requires that the nut be installed on the center of the screw shaft. The return tubes of the ball nut must be oriented upward so that the ball nut will not overtravel. The adjusting nut must be tightened against a spacer or spring washer, then the nut is placed on the screw shaft. The nut should be rotated several times in both directions to ensure that it is centered.
Ball screw nuts are typically manufactured with a wide range of preloads. Large preloads are used to increase the rigidity of a ball screw assembly and prevent backlash, the lost motion caused by a clearance between the ball and nut. Using a large amount of preload can lead to excessive heat generation. The most common preload for ball screw nuts is 1 to 3%. This is usually more than enough to prevent backlash, but a higher preload will increase torque requirements.
The diameter of a ball screw is measured from its center, called the ball circle diameter. This diameter represents the distance a ball will travel during 1 rotation of the screw shaft. A smaller diameter means that there are fewer balls to carry the load. Larger leads mean longer travels per revolution and higher speeds. However, this type of screw cannot carry a greater load capacity. Increasing the length of the ball nut is not practical, due to manufacturing constraints.
The most important component of a ball screw is a ball bearing. This prevents excessive friction between the ball and the nut, which is common in lead-screw and nut combinations. Some ball screws feature preloaded balls, which avoid “wiggle” between the nut and the ball. This is particularly desirable in applications with rapidly changing loads. When this is not possible, the ball screw will experience significant backlash.
A ball screw nut can be either single or multiple circuits. Single or multiple-circuit ball nuts can be configured with 1 or 2 independent closed paths. Multi-circuit ball nuts have 2 or more circuits, making them more suitable for heavier loads. Depending on the application, a ball screw nut can be used for small clearance assemblies and compact sizes. In some cases, end caps and deflectors may be used to feed the balls back to their original position.
