In physics, the torque is given as the twisting force that generate rotation of object. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Lets say youre a shipowner, and you are concerned that your newly re-engined ship is not outputting the horsepower that it should be. Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. n1/n2 = 1450/1.9 = 763 (here is the choice of four-stage motor), Therefore: P1N = P1 * f1 = (500 * 1450) * 1 / (9550 * 763 * 0.85) = 0.117 (KW) so we generally choose 0.15KW speed ratio is about 763 enough to cope with. Gearbox output torque refers to the actual working output torque. Torque is proportional to excitation flux and armature current. T-torque; 9550-constant (do not have to find outits source); P-motor power (KW); n-output speed (rev/min r/min) Note: if When calculating the torque through the reducer gearbox, the factor of gear transmission efficiency loss should be considered. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Gravity = 386 in/sec. In physics, the torque is given as the twisting force that generate rotation of object. Torque measurement can provide you the information you need to keep heavy industrial and manufacturing machinery up and running properly and efficiently. In imperial units the Full-load Torque can be expressed as, T = 5252 Php / nr (1), nr = rated rotational speed (rev/min, rpm), In metric units the rated torque can be expressed as, T = 9550 PkW / nr (2). The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isn't work or energy, so should just be newton-meters). By using our site, you agree to our. You would find that the torque is 188 Nm: For example, suppose you're trying to figure out the magnitude of torque on a solid disc. How to calculate the torque of the reducer? Instead, the lug wrench fits onto the lug nuts so that it is at a 15% incline to the horizontal. The load is constant power, then T and N is basically the inverse relationship. You can compare your horsepower calculation to what the manufacturer has stated to see how your ship is performing. T = 9.55 * P / N, T output torque, P power, N speed, the motor load has a constant power and cross-torque points, constant torque, T constant, then P and N is proportional relationship. Definition and Equations, Difference Between Independent and Dependent Variables, M.S., Mathematics Education, Indiana University, The same argument as above applies to cases of. The service factor is also called the using factor or safety factor; especially for users who select the gearbox, the gearboxs use factor should be determined in combination with other factors like working conditions and driven machinery. If you know the torque of the equipment T2 and the rated speed of the motor n1 and the output shaft speed n2 and drive the equipment system f1 (this f1 can be defined according to the actual operation of the site, most of the domestic 1.5 above) and the motor power factor m (that is, the ratio of work to total work, in the motor winding can be understood as the slot full rate, generally in 0.85). The above equations are particularly helpful when there is a single known force acting on an object, but there are many situations where a rotation can be caused by a force that cannot easily be measured (or perhaps many such forces). One stage helical gear unit: 95%, two-stage helical gear unit:90%. It looks ugly in calculation, since it is not standard, but it works! To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. In the torque equation, this distance is represented by "r" for radius or radial vector. Unfortunately, that doesn't work. in). Jones, Andrew Zimmerman. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. The Pull-up Torque is the minimum torque developed by an electrical motor when it runs from zero to full-load speed (before it reaches the break-down torque point). Load torque : T LR = Nmax 9550 P LR [N . Sign up to receive the latese information from us. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The Full-load Torque is the torque required to produce the rated power of an electrical motor at full-load speed. For this reason, you'll sometimes see it represented with an "r" in the basic torque equation. https://courses.lumenlearning.com/suny-osuniversityphysics/chapter/10-6-torque/, https://www.khanacademy.org/science/physics/torque-angular-momentum/torque-tutorial/a/torque, https://www.grc.nasa.gov/WWW/K-12/airplane/torque.html, https://www.khanacademy.org/science/in-in-class11th-physics/in-in-system-of-particles-and-rotational-motion/in-in-torque-and-equilibrium-ap/a/torque-and-equilibrium, https://openstax.org/books/university-physics-volume-1/pages/10-7-newtons-second-law-for-rotation. Motor power = torque 9550 Rated powers motor input speed /Ratio /service factor. How do you calculate the torque of a gearbox? Torque Formula. Input the value that you wish to convert. For example, suppose you know that the moment of inertia for an object is 10 kgm. You need both horsepower and torque to be able to accurately quantify the performance of an engine. That value is dependent on both torque and RPM. This image may not be used by other entities without the express written consent of wikiHow, Inc.
