Abstract
Series -parallel connection formula cycloid gear reduction unit comprises casing (J) first order speed reducing component (J1) second level speed reducing component (J2), its whole shape is greater than axial length's disc for the diameter, the simple weighing pan speed reducer that appears, the middle section has the flange of slow running and operating mechanism to join and output power. The one -level is slowed down to the external toothing, and the double reduction is the inner gearing, the profile of tooth curve parametric equation formula of two -stage adopts the same rolling diameter, makes its inside and outside two vice centre -to -centre spacing A of meshing equal that then the radial dimension of 3 input shafts is the same, and a plurality of part sizes such as bearing, bearing cap are also the same. Its speed reducing ratio series does: 40, 60, 84, 112, 144, 180, 220, 264, 312, 364. It is big to have the velocity ratio, small, light in weight, and the noiselessness is difficult for calorifing, and characteristics such as reliable operation are particularly suitable for the reciprocal rotary mechanism in elbow joint of robot or manipulator to reach other low -speed, heavy rotary mechanism.
Description
Technical field:
This utility model relates to a kind of series parallel type cycloid gear reductor, and feature can be called for short dish type reductor in shape.
Belong to mechanical transmission fields.It is particularly suitable for the ancon articulation mechanism less than 180 degree of robots repeatedly rotated or mechanical hand；Also
It is suitable for low speed, heavy duty and requires the narrowest narrow special environment condition of installing space.
Background technology:
In prior art, for the gearing under specific condition, typically use Involutes Gears Transmission, or cycloidal pin more
Wheel transmission.But, these transmissions have following shortcoming unavoidably:
1, heating: improve the temperature of lubricant, reduces the life-span of bearing, reduces transmission efficiency.
2, noise: affect the quiet environment of operator, strengthen feeling of fatigue and affect workers ' health.
3, volume is bigger: take the overall space that lathe is more.
4, weight is bigger: consume metal material more.
For disadvantages mentioned above, this utility model uses the cycloid gear Meshing Pair rolled in opposite directions, the theoretical analysis and calculating,
Its flank of tooth sliding velocity is the lowest, only the 1/10 of involute gear, overcomes noise and heating problem.
Another distinguishing feature of cycloid gear Meshing Pair, is that high speed shaft is equivalent to " the tooth axle of only one of which tooth ", plays
The structural principle advantage of " the little then size of speed ratio is little ", use existing parallel connection have again series connection, should external toothing internal messing again two
Level hybrid connected structure, it is achieved the target of " small size is big passes ratio ".
Tooth shape character the most of the present utility model: tubbiness is plump, there are not tensile, compressive, bending, cuts equal strength problem, Ke Yishe
Count out volume little, lightweight special reductor, not only to save a large amount of metal, reduce cost, and efficiency is the highest, work can
Lean on.
Summary of the invention:
In order to solve the problems referred to above, present invention content is as follows:
