    CZPT Torque Limiter Products

    Whether you’re looking for a magnetic torque limiter or a permanent-magnet synchronous limiter, CZPT(r) has a torque limiter solution for you. In addition to these products, we also offer Roller-detent and Challenge torque limiters.

    Over-torque limiters

    During heavy duty high cycle operations, it’s critical to have the proper equipment for maintaining torque levels. Having the right torque limiters can protect your machine from damage and help to reduce the frequency of downtime and cost of repair.
    Torque limiters work to prevent the buildup of rotational energy, which can cause mechanical overloads. The torque limiter system detects the overload and disconnects the drive from the driven components. When the torque level drops below the preset level, the device reengages.
    Torque limiters are widely used in industrial and assembly line applications. They are used in manufacturing equipment such as industrial robots and printing and converting machines. They are also used in conveyors and woodworking machines.
    There are many types of torque limiters available. The most common are mechanical and hydraulic. The mechanical torque limiters can be installed in a single point or multiple points in the machine. Hydraulic torque limiters are a compact option for accurate torque overload release. They also allow users to set a precise disengagement torque value.
    Typically, these devices are adjustable with a single screw. For offset mounted systems, an external bearing may be required. Most quality torque limiters include a bearing between the base of the clutch and the output flange.
    Mechanical torque limiters are available in a variety of sizes and designs. They can be used in virtually any application. They provide an integrated mechanical and electrical design.limiter torque

    Magnetic torque limiters

    Using Magnetic Torque Limiters will increase the reliability and durability of your equipment. They also help prevent catastrophic failure, which is essential for preventing downtime. They are used in a wide range of applications, including printing and converting machines, woodworking machines, conveyors, and many more.
    They are designed to disengage from the driven system when the torque load exceeds the design limit. This protects rotating equipment and machinery from torsional strain and other hazards. They are also designed to provide precise overload protection. Using a torque limiter can protect equipment through its entire life cycle. It may prevent a mechanism from failing or even prevent a workplace accident.
    A torque limiter is typically packaged as a shaft coupling. It is also available in other forms, such as friction-plate couplings and magnetic particle couplings. It is also available in many different sizes. It is important to choose a torque limiter that is right for your needs. The design of the torque limiter must match the type of torque load generated.
    They are used in a variety of applications, including speed and torque sensors, acceleration sensors, position sensors, and more. They also can be found in various counters, tachogenerators, scales, and measuring devices.
    Magnetic torque limiters are lightweight, require no maintenance, and don’t suffer wear and fatigue. They also can be used at any temperature. They have a quick response time, and they can reduce the transmission of torsional vibrations.

    Permanent-magnet synchronous torque limiters

    Various types of torque limiters are available in the market. These include friction torque limiters, magnetic particle clutch torque limiters, and spring-loaded pawl-spring torque limiters. These devices are used to limit the torque transmitted from an input shaft to an output shaft. These devices reduce the force experienced by the drive train components and thus enhance the reliability of electromechanical actuators. They protect expensive components from damage and physical injury.
    In a magnetic particle clutch torque limiter, a magnetic field is generated from current. This field is transmitted to an output shaft through a physical barrier or air gap between the magnetic field lines. Magnetic particles in the assembly lock into chains along the field lines. The torque generated is statically or dynamically set. The torque is proportional to the current passing through the windings.
    Friction torque limiters are used in various applications such as robotics. These devices have a radial and axial design. They also utilize sensors to prevent overload. These devices are also used as shaft-to-shaft couplings. The torque density is good and the devices are easy to operate.
    Permanent-magnet synchronous torque limiters are another type of torque limiters. This type uses twin discs with mated magnets on their faces. These devices are fast acting and provide quick response. They can also have backlash.
    In a permanent-magnet synchronous torque limiter, the magnetic field is generated from an excitation source. This field then interacts with a PM field to generate torque.limiter torque

    Roller-detent torque limiters

    Whether you’re working on a manufacturing or processing line, it’s important to be aware of the various types of torque limiters and how they work. They can protect your equipment from overload and damage, and prevent physical injury to personnel. These devices can also be used in industrial robots, assembly lines, printing and converting machines, and conveyors.
    Torque limiters can be mechanical, pneumatic, or electronic. Some systems have a single-position device, while others have a flexible coupling model that allows small parallel offsets and angular misalignments. Some systems also offer random reset devices.
    Torque limiters are designed to protect expensive components from overloaded conditions. Modern machines have a predictable motion and torque, but unexpected forces can exceed their design limits. They can also eliminate physical injury by isolating driving and driven equipment from each other when overload occurs.
    Mechanical torque limiters are available in a wide range of sizes and are designed for use in virtually any application. They are also backlash-free and offer superior repeat accuracy. They are ideal for processing different materials, and are suitable for applications such as woodworking.
    Electronic torque limiters are less expensive than mechanical devices, and offer a more reliable control mechanism. They can apply pressure to thrust flanges and control the volume of air in the air chamber. They are commonly used in sheet metal processing equipment, printing and converting machines, and industrial robots.

    CZPT(r) Tolerance Ring

    CZPT(r) Tolerance Ring is a custom-designed component that is used to transfer torque and axial force between mating components. The component can be used as a slip clutch and as a force limiter.
    The tolerance ring may be made from metal, such as nickel-copper, spring steel, carbon steel, or copper-beryllium. The material may be heat-treated to provide the desired hardness and durability. The tolerance ring is typically curved to facilitate assembly. The tolerance ring can also be manufactured as an annular band.
    The tolerance ring includes a generally cylindrical body. The body may be formed with a slit down the side. The body may also be constructed with one or more rows of projections. A tolerance ring is typically located between the inner component and the outer component. The tolerance ring transfers torque between the inner and outer components.
    A tolerance ring may have an apex radius of no less than 1.01 RB. The base radius is measured perpendicularly from the ring’s central axis to the outer surface of the apex.
    A tolerance ring may be arranged in a centered or piloted configuration. A centered configuration requires grooves in the bearing housing. A piloted configuration uses a step instead of a groove.
    In a two-layer tolerance ring configuration, the first layer may include a plurality of radially extending projections. The second layer may include a smooth, regular surface. The two layers may overlap in some locations. When the layers overlap, the second layer may act as a sleeve around the inner component. The second layer may also act as a diffuser for transmitted force.limiter torque
