A torque limiter is a mechanical device that prevents mechanical overload by controlling the amount of torque the drive shaft is subject to. It can completely decouple the load or allow it to slip during overload. There are several designs, including shear pins, synchronous magnets, bawl catch and pawl, friction plates, magnetic particles, and magnetic […]
Bolts have specific tolerance levels determined by material, size, and torque capacity. PSI tables guide technicians to prevent overtightening. Torque wrenches measure PSI and prevent overtightening. Head and lug bolts have specific torque requirements. Bolts are designed to securely fasten objects together. Each bolt has specific tolerance levels before failure. This tolerance level is determined […]
Stall torque is the torque of a device at zero rotational speed or the torque load required to bring it to zero. Electric motors, steam engines, and hydrodynamic drives produce stall torque. Torque converters multiply stall torque and have ratios ranging from 1.8:1 to 2.5:1. The formula relating torque, stall torque, and RPM is T=Ts-(NTs/Nf). […]
Torque is the force needed to rotate an object around an axis. Starting torque is the force needed to initiate rotational motion, determined in part by static friction. It is important in threaded fasteners and cylinder engines, where too much or too little torque can cause issues. In physics and mechanics, torque is the rotational […]
A torque sensor measures rotational force on machinery and transmits the data to control systems. The sensor is classified as rotary or reaction and can handle different loads and drives. To prevent measurement errors, a rotating sensor can be used. The type of engine and load force affects the sensor’s rating. It is used in […]
Torque keys adjust the load on a car’s torsion bars, allowing for suspension stiffness or softness. Adjusting the keys can raise or lower the vehicle, but it can also be dangerous and cause premature failure of suspension components. It is recommended to record the number of turns made to each side for consistency. Torque keys […]
Front-wheel drive cars can experience torque steering, causing the vehicle to jerk to one side under heavy acceleration. Uneven driveshaft length is the most common mechanical cause, but other factors such as poor tire sidewall design and differences in the road surface can also contribute. Maintaining a constant incremental acceleration can mitigate torque steering. Steering […]
Variable torque is when a motor directs power to a load as needed, reducing power when too much is detected. It is found in cars, hybrid cars, snowmobiles, ATVs, and aircraft. It saves fuel and provides cleaner emissions. Variable torque is described as the ability of a motor to direct power in a limited way […]
The torque reaction is the equal and opposite reaction to a rotating force, and is important in both helicopters and ground vehicles. In helicopters, the tail rotor or tandem rotors counteract the torque reaction caused by the main blades, while in motorcycles, the torque reaction allows riders to do a wheelie. The torque reaction is […]
Direct torque control optimizes and maintains AC motor operation by monitoring voltage and current to regulate power and maintain optimal torque and flux ranges. It has numerous industrial applications, but requires high-quality measurement equipment and fast computers for effective implementation. Direct torque control is a method of optimizing and maintaining normal operation, typically within an […]
A torque wrench measures the circular force when tightening bolts or nuts and comes in various styles and complexities. A spoke torque wrench has a flexible arm and scale, while a click torque wrench can be set to deliver a specific amount of torque. They vary in price and size depending on the application. A […]
A torque screwdriver applies precise rotational force to fasteners. It is available in manual, pneumatic, and electric versions, and has a pressure-sensitive clutch to control torque. Consistent torque improves structural integrity and stability. Regular calibration is necessary for accurate results. A torque screwdriver is a tool used to turn screw head fasteners into precise, even […]
Friction torque is the force that causes an object to rotate around an axis. It is affected by the friction between two objects, and is used in machines such as automobiles. Frictional torque can cause problems in machines, but can be controlled with torque limiters. Friction torque is the force between two objects that causes […]
An air torque wrench applies a specific amount of torque to a fastener using compressed air. It is smaller, more powerful, and cheaper than electric or manual versions. It is commonly used in engineering applications where precise tensioning is required for multiple fasteners. An air torque wrench is a pneumatic tool designed to apply a […]
Actuator torque is the amount of twisting force an actuator can produce. It determines the range of loads the actuator can handle, with higher torque allowing for a wider range. Torque is also important in tools and vehicles, where it affects performance. Actuator torque is a quantitative expression of the amount of torque an actuator […]
