The present invention adopts following a kind of mechanism to replace existing waveguide generating mechanism: be clamped on the input shaft one radially between square position and waveguide bevel gear with one group of different planet rolling element of diameter, a planet frame keeps the interelement relative position of planet rolling, and guarantees their revolution motion radius.
Because the waveguide bevel gear is held on input shaft or output shaft or the frame by universal hinge knot mechanism rack, for guaranteeing the normal engaged of bevel gear pair, the planet rolling element among the present invention can not be less than two.
It is on the determined planet revolution orbit in square position in all optional planet rolling elements maximum one that the size of one group of planet rolling element and the best mode of distribution are wherein maximum one, be that it is in input shaft radially square position face and the waveguide bevel gear back side are apart from the position of maximum on the planet revolution orbit, other planet rolling element evenly distributes according to the circumference of planet revolution orbit.The good engagement state of bevel gear pair when this mode can guarantee the waveguide campaign.
The present invention has three kinds of embodiments about the planet rolling element, a kind of is to use the different steel ball of diameter as the planet rolling element, a ball-collecting rack is as the planet frame, the steel ball circumference slot rolling that on the radially square position of input shaft a cross section to be arranged be circular arc, during the input shaft rotation, radially the square position forces rolling element to do planetary motion, causes the waveguide campaign of waveguide bevel gear.The diameter of circular cross-section is got the diameter of maximum planetary steel ball.
Second kind is as the planet rolling element with one group of roller, roller is made planet rolling between the radially square position card of input shaft and the waveguide bevel gear back side, the wheel shaft of roller is vertical with input shaft, and is connected with the planet frame, and the planet frame is held on the input shaft by bearing bracket stand.
More than the characteristics of motion of two kinds of embodiments when being desirable transmissions, be that the friction driving at planet rolling element and square position and waveguide bevel gear back is when non-slip, every two weeks of rotation of input shaft, the waveguide bevel gear is finished the waveguide campaign of one-period, be equivalent to increase a gear-stage velocity ratio and be 2 deceleration prime in existing bevel-gear waveguide speed-reducer, this is because planetary component is basic identical in the revolution radius of a circle at square position and waveguide bevel gear back.
The third is as the planet rolling element with one group of tapered roller.In this case, the planet rolling element is line with square position radially with the waveguide bevel gear and contacts.
Because, the revolution radius of a circle R of tapered roller on the square position is obviously greater than the revolution radius of a circle r at waveguide bevel gear back, so finish the waveguide campaign of one-period, input shaft rotated less than two weeks, and the reduction speed ratio of waveguide generating mechanism is 2r/R during desirable transmission.
