Worm copper processing plant worm worm drive shaft for motion and power transfer between the two space staggered. Exercise can be growth or slow down, the most commonly used is the stagger angle of 90 ° deceleration both axes. Helix direction may be right-handed or left-handed, right-handed take on more general. Helical direction of the worm and the turbine must be consistent. Worm drive vibration, shock and noise are very small, work more stable, able to get a larger single-stage transmission ratio, compact structure, it can be self-locking. Its main drawback is the low ratio gear transmission efficiency, require expensive anti-friction non-ferrous metals. Worm drive transmission structure is composed by the worm and worm wheel, for transferring interlaced motion and power shaft, usually two-axis cross angle of 90 °. Worm Drive in general, are active members in the worm. Judging from the appearance, similar worm screw, worm gear is much like Helical Gear. In operation, the worm gear tooth surface along the helical worm for sliding and rolling. In order to improve the exposure of teeth, the worm gear formed along an arc-shaped tooth width direction, so that the worm is partially enclosed. When such a worm gear meshing line contact rather than point contact. Depending on the tooth profile, ordinary cylindrical worm can be divided into Archimedes Worm (ZA worm), involute worm (ZI worm), the normal straight profile worm (ZN worm), cone enveloping cylindrical worm and other four species. Archimedes Worm (ZA worm) this worm, in the vertical plane (ie, end face) to the axis of the worm, the tooth profile of Archimedes spiral (Fig Archimedes Worm), in a plane containing the axis The tooth profile (ie axial tooth profile) is linear, its profile angle α0 = 20 °. It is available in single-pole lathe with a straight edge (when the lead angle γ≤3 °) or pole (when γ> 3 ° when) turning. When installing the tool, the top surface of the cutting edge must pass the worm axis, as shown in Figure Archimedes Worm. This worm grinding difficult, when the lead angle is large processing inconvenience. Normal straight profiled end face of this worm worm (ZN worm) tooth profile extending involute (normal straight profile worm>;), France face (NN) tooth profile is a straight line. ZN worm is turning on a lathe with a line of single-pole or double-pole blade. Installation is shown in the form of the tool; Fig. Grinding it is also more difficult this worm. Involute worm (ZI worm) that the end face of the worm tooth profile involute (FIG), so it is equivalent to a small number of teeth (teeth equal to the number of worm head), large helix angle of involute helical gears. ZI worm two straight cutting edge tools available in the lathe turning. The top surface of the blade should be tangent to the base cylinder, where a high cutter Our main production: spur gears, gear shafts, small modulus gear, spiral bevel gear (bevel gear) helical gears, worm gears and other special-shaped (each seed material), etc. A number of standard models can be customized, cost effective, large more favorable.
