Abstract
The utility model relates to a non-rotating self-locking reducer with internal teeth driving and small teeth difference, which is characterized in that: when the input shaft rotates, the bearing sleeve of the eccentric shaft is driven to rotate and then the swing disk of the internal gear ring covering on the bearing sleeve is driven, and the swing disk of the internal gear ring only can do eccentric plane swinging but cannot rotate because of the hindrance function of a fixed disk; when the internal teeth and the external tooth are driven with one tooth difference, as long as the eccentric input shaft rotates every circle, the swing disk of the internal gear ring strikes one tooth of the external gear on the output shaft of the external gear to the opposite direction, and as the input shaft rotates continuously, the output shaft rotates continuously with slowing down; when the input shaft stops rotating, the swing disk of the internal gear ring stops swinging because of the function of the fixed disk, and the output shaft of the external gear stops and then the self locking is realized. The utility model has the advantages of compact structure, few transmission links, transmitting power directly from the input shaft to the output shaft, big speed ratio, small size, high efficiency, small heating, small noise, strong self-locking, long service life and reducing the cost by two-thirds than the original apparatus. The utility model can be made to a micro-structure of big speed ratio and has wide application range as a result.
Description
Technical field:
The utility model relates to a kind of few tooth difference speed reducer of internal tooth transmission, and particularly a kind of ring gear does not rotate, and has few tooth difference self-locking speed-down machine of the non-rotating internal tooth transmission of self-locking property.
Background technique:
Few its input shaft of tooth difference speed reducer of present known internal tooth transmission and output shaft are all not possess self-locking property by the rotation transmission, must be provided with middle output mechanism for transmitted power and motion simultaneously, so structure is not compact, part is many, frictional loss and power loss is big, heating greatly, efficient is low, noise is big, cost is high.But the worm drive self-locking, but volume is big, efficient is low, the life-span is short, expend a large amount of non-ferrous metals.
Summary of the invention:
The utility model is for solving the technical problem that exists in the known technology, and provide a kind of restriction ring gear to rotate, input shaft directly connects with output shaft, input shaft is directly passed to output shaft to power, the internal tooth transmission has few tooth difference self-locking speed-down machine of a kind of irrotational tooth transmission of auto-lock function by stirring transmission.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the input part is made up of input shaft, bearing, eccentric shaft bearing sleeve, key, ring gear wobble-plate, fixed tray, bearing pin, side cover.Input shaft one end is bearing on the side cover with bearing, and the other end is fixed with key and eccentric shaft bearing sleeve, bearing outer ring and ring gear wobble-plate drive fit, and ring gear wobble-plate outside cover fixed tray, their garden has aperture on week, wherein inserts bearing pin; Output is made up of support, bearing, external gear output shaft, and the external gear output shaft is bearing on the support by bearing, external gear and ring gear engagement;
Side cover, fixed tray, support connect with bolt.
The utility model can also be taked following technical measures: the aperture on described ring gear wobble-plate and the fixed tray is that its hole diameter is identical at the center line of the garden of certain diameter halving hole on week; Its diameter of described bearing pin is less than hole diameter; The profile of tooth of described ring gear and external gear is involute, cycloid, triangle equiconjugate curve profile of tooth.
Advantage and the good effect that the utlity model has are: can not rotate because of ring gear is subjected to the restriction of fixed tray, only doing off center plan moves, garden Zhou Yundong is in its axle center, the internal tooth transmission is for stirring transmission, transmission is irreversible to have self-locking property, input shaft power is directly passed to output shaft simultaneously, simplified part, reduced processing technology, frictional loss and power loss, the reaction arm of force increases, noise is little, the efficient height, cost has descended 2/3, volume can be littler and have enlarged using scope, also can make the large speed ratio microstructure, can replace worm drive because of having self-locking performance again, not only saved the space, also saved the nonferrous materials of a large amount of costlinesses, and improved working life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model major part axle side schematic representation.
Embodiment:
For further understanding summary of the invention of the present utility model, characteristics and effect exemplify following examples now, and conjunction with figs. is described in detail as follows, and see also Fig. 1, Fig. 2.As shown in Figure 1 and Figure 2: input shaft 1 one ends are bearing on the side cover 11 by bearing 13, and the other end is fixing with eccentric shaft bearing sleeve 2 with key 3, bearing outer ring on the eccentric shaft bearing sleeve 2 and ring gear wobble-plate 5 drive fits, its outer fixed tray 4 that is with.Week place, the garden of certain diameter waits minute 6 center holes on ring gear wobble-plate 5 and fixed tray 4, the equal diameters in its each hole, insert bearing pin 9 in the hole, its diameter is less than the diameter in hole, bearing pin 9 can freely rotate in the hole, fixed tray 4, support 6 are fixedly connected with side cover 11 usefulness bolts 10, external gear output shaft 7 is bearing on the support 6 by bearing 8, in order to reduce the couple of balance, it is enclosed within on the output shaft 1 and add counterweight 12 in the middle of the end face of side cover 11 and ring gear wobble-plate 5 when input shaft 1 high speed rotating.During work, input shaft 1 rotates by key 3 and drives 2 rotations of eccentric shaft bearing sleeve, but be subjected to the restriction of fixed tray 4 because of ring gear wobble-plate 5, it can only do under the effect that 6 bearing pins 9 move in aperture that off center plan moves but garden Zhou Yundong is in the axle center, so the ring gear on the ring gear wobble-plate 5 is a planet wheel, the external gear engagement of the ring gear 7 of the ring gear wobble-plate 5 that drives because of input shaft 1 and external gear output shaft 7 again.The power of output shaft 1 is directly passed to external gear output shaft 7.The number of teeth of ring gear, can Duo that one or several promptly forms a tooth difference or multiple tooth poor than the external tooth on the external gear output shaft 7, if a tooth difference then the input shaft 1 ring gear wobble-plate 5 that rotates a circle just stir the external gear output shaft and turn over a tooth, different gear ratios can obtain different reduction speed ratio, so this speed reducer be the internal tooth transmission by stir transmission it can only positive transmission can not be reverse, output shaft 7 could rotate when promptly having only input shaft 1 rotation, and output shaft oneself can not rotate, and therefore has self-locking performance.This speed reducer one gear-stage velocity ratio is 1/6-1/100, also can multistagely contact, optional speed ratio.It can make the large speed ratio microstructure, and application area is extremely wide.
