TPAPlanar enveloping toroidal wormThe reducer (JB/T9051-1991) is a flat primary gearboxEnveloping worm gear reducerTransmission. Center distance: 100, 125, 160, 200, 250, 315, 400, 500. Speed ratios: 10, 12.5, 16, 20, 25, 31.5, 40, 50, 60. Planar torusEnveloping worm gear reducerIt is an emerging transmission device with high load-bearing capacity, high transmission efficiency, compact and reasonable structure. suchworm gear reducerIt can be widely used in deceleration transmission of various transmission machinery, such as metallurgy, mining, lifting, chemical, construction, rubber, shipbuilding and other industries, as well as other mechanical equipment. The suitable working environment temperature is -40 ℃~+40 ℃, the input shaft speed is not more than 1500 revolutions per minute, and the worm shaft can rotate in both directions. This reducer is designed in accordance with the Chinese mechanical industry standard JB/T9051-1999 "Flat Envelope Ring Surface"Worm reducer》Design and manufacture.
