Selection envelope reducer should know: the prime mover, the work load of the machine type and nature pw envelope reducer, the average daily operating time, start frequency and ambient temperature. 1) gear commonly used sump lubrication, smooth action when the worm computing speed vs> 10m / s, the use of forced lubrication. 2) synthetic worm gear oil. 3) gear lubricating oil viscosity index should be greater than 100. 4) gear lubricant oil press table. Allows the use of lubricating properties comparable to or higher oil. Lubricating oil (recommended lubrication). 5) gear splash lubricated bearings hwwb envelope reducer, can also be greased. Plane double enveloping gear is on a very wide industrial use machinery, its invention has great significance for improving productivity, but also a change in the mechanical manufacturing industry. Plane double enveloping worm Vice is a flat surface for the mother, through a phase in a circular motion, enveloping the tooth surface of the worm, then the worm tooth surface for female faces, by the relative motion of the envelope of the worm tooth surface. Plane double enveloping worm with ordinary cylindrical worm and worm Hindley, compared with the following characteristics: the worm is Worm, while increasing the number of teeth meshing with the worm; after hardened precision ground worm tooth surface cut from the tooth surface hardness, surface roughness rating table tpa80 envelope reducer, can achieve high precision tooth; tooth surface contact area is large envelope reducer, and instantaneous contact wire, the total length of the contact line lengthened. Tooth surface lubrication angle, and the engagement is easy to form hydrodynamic oil. Plane double enveloping gear is "flat envelope worm reducer" designed and manufactured in accordance with the People's Republic of China Machinery Industry Standard JB / T90501-1999, the allowable operating speed of not more than 1800rpm, the worm can forward and reverse rotation, work Ambient temperature tail -40 ℃ ~ + 40 ℃, can be widely used in metallurgy, mining, lifting, transportation, chemical, construction and other gear transmission machinery. pwo envelope reducer | Wulanchabu envelope reducer | Runchi gear provided by the Texas Runchi reducer Limited.
