Hamenako worm module harmonic reducer SHG-65-160-2SO, a flexible wheel with external teeth that can produce radial elastic deformation when working, and a wave generator with elliptic shape and flexible rolling bearing on the outer ring installed in the internal transmission part of the flexible wheel. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
In addition, the structure of worm wheel hub should be axially symmetric with the middle plane of tooth width. The middle line of worm tooth width should be symmetrical with the middle line of left and right axes as far as possible. This design is because worm tooth is easy to wear parts. After one side of worm working face is damaged, the smoke wheel or worm can be installed in reverse, and the other side of tooth face can continue to work.
Enveloping ring surface worm drive has developed very rapidly in China in recent years, especially in the early 1960s, China began to introduce the development of plane enveloping ring surface worm drive, has been able to manufacture the diameter of 2160mm precision indexing plane worm gear pair, used in astronomical telescopes, One tooth motion error is less than 1.1971 Shougang and metallurgical department of China successfully created the planar secondary enveloping ring surface worm drive.
From the perspective of meshing characteristics, under the reasonable selection of parameters. The instantaneous contact line of the transmission, its shape and distribution position is in favor of the establishment of the sliding oil film state, so the transmission efficiency of the Harmonics reducer SHG-65-160-2SO of Hamenako worm module is obviously improved than the ordinary cylindrical worm transmission, thus its bearing capacity may also be greatly improved, but the test data is still not sufficient.
The graded curved side is a worm with a mass torus. Called ring and worm. A ring surface worm, when its axial tooth profile is straight, is called straight profile ring surface worm (commonly known as spherical worm) Hamenako worm module harmonic reducer SHG-65-160-2SO, and the corresponding worm drive is called straight profile ring surface worm drive
