NMRV worm gear reducer form Description:
Reducer input is divided into: hole input, shaft input, extension
worm shaft; reducer output type is divided into: hole
output, one-way shaft output, two-way shaft output. Third, NMRV
worm gear reducer installation.
I. nmrv reducer Overview worm worm gear is driven by the cross-axis
helical cylindrical gear drive evolved. The
pinion of the pinion is wound on a cylindrical surface for more
than one week. Such a pinion is like a screw, called
a worm. Large gears are called worm gears. In order to improve the
meshing condition, the worm indexing
cylindrical surface of the busbar into a circular arc, so that the
worm part of the package, and with the worm
shape and parameters of the same hob Fan processing worm, so that
the tooth profile between the line contact ,
Can pass a larger power.
Worm worm gear drive features: 1. It is a special cross-axis
helical gear drive, the angle of ?? Σ = 90 °, z1 little,
generally z1 = 1 ~ 4;
1. It has some characteristics of the spiral drive, the worm is
equivalent to the screw, the worm wheel is
equivalent to the nut, the worm part of the understanding of the
worm. Nmrv series worm gear reducer series
according to Q / QS1-1999 technical quality standards design and
manufacturing. Nmrv series worm gear
reducer in line with the national standard GB10085-88 cylindrical
worm wheel on the basis of parameters, learn
from the most advanced technology at home and abroad, unique
novelty "square box" shape structure, high-
quality aluminum die-casting
