Example two
The method for installing the planet carrier 2 comprises the steps of arranging the first bearing 1, wherein the first bearing 1 and the planet carrier 2 are coaxially arranged, an inner ring of the first bearing 1 is attached to a cylindrical peripheral section on the planet carrier 2, an outer ring of the first bearing 1 is attached to a cylindrical inner section on the inner gear 3, and the inner gear 3 is meshed with a planet gear 4 corresponding to the planet carrier 2. The contents of this portion are the same as those of the first embodiment, and the technical effects are not described herein again.
As shown in fig. 2 and 3, on the basis of the above structure, the first bearing 1 and the internal gear 3 are fixed by clearance fit, and an elastic buffer ring 6 is provided, wherein the elastic buffer ring 6 is disposed around the periphery of the first bearing 1, attached to the outer side of the first bearing 1, and disposed in a first mounting groove 31 disposed on the internal gear 3 in a pressed state.
The bearing is fixed in a relatively conventional mode through an interference fit mode, a standard size table is provided for the installation of the bearing, but in the invention, the planet carrier 2 is different from parts such as shafts and the like which are conventionally supported by the bearing, so for the installation requirement of the first bearing 1, a new mode is provided in the embodiment, namely, the elastic buffer ring 6 is added, and through the arrangement of the elastic buffer ring 6, when the operation of the first bearing 1 fluctuates, the vibration and the like caused by the fluctuation can be alleviated through the buffer effect of the elastic buffer ring 6 in a pressed state, so that the operation stability of the planetary reducer is improved.
As a preferable mode of the second embodiment, as shown in fig. 4 to 6, the elastic buffer ring 6 is provided as a combined structure of an inner buffer ring 61 and an outer buffer ring 62; the inner buffer ring 61 comprises a hollow cylindrical inner ring body 61a and a plurality of annular convex edges 61b arranged on the outer side of the inner ring body 61a, the annular convex edges 61b are arranged in parallel along the axial direction of the inner ring body 61a, and two sides of the inner ring body 61a are arranged at intervals with the side wall of the first mounting groove 31; the outer buffer ring 62 comprises an outer ring body 62a in a hollow cylindrical shape and support ring bodies 62b protruding from two edges of the inner side of the outer ring body 62a, and the two support ring bodies 62b are symmetrically arranged; the support ring body 62b includes a side surface 62b1 and an abutment surface 62b 2; the side surface 62b1 is spaced apart from the side wall of the first mounting groove 31, and the outer ring body 62a is retracted inward relative to the side surface 62b 1; the abutting surface 62b2 is connected to the side surface 62b1, and the abutting surface 62b2 is a curved surface and is abutted against the inner ring 61 a.
Each annular protruding edge 61b is located between the two support ring bodies 62b, and before the first bearing 1 is installed and works, the annular protruding edges 61b and the outer ring body 62a are arranged at intervals, the interval distance is smaller than the gap distance between the first bearing 1 and the inner gear 3, and the outer buffer ring 62 is pressed by the inner buffer ring 61 under the extrusion of the support ring bodies 62 b.
As shown in fig. 7, in the state shown in the figure, the first bearing 1 is not operated yet, and therefore, the deviation of the installation position occurs without being affected by the operation of the speed reducer, and a predetermined gap exists between the first bearing 1 and the internal gear 3, and the gap is generated by the clearance fit between the first bearing 1 and the internal gear 3, wherein the range of the gap is preferably controlled to be 0.05 to 0.3mm, so that the fluctuation which may occur in the first bearing 1 is effectively controlled, the gap is filled by the inner ring 61a, the inner ring 61a and the bearing are tightly attached by the elastic force generated by the outer cushion ring 62, and the edge of the inner ring 61a is also properly pressed at this time.
In the above preferred solution, the fluctuation generated when the planet carrier 2 drives the first bearing 1 is buffered by two stages:
primary buffering: for the buffering of the non-laminated small range of the first bearing 1 and the inner gear 3, the buffering is mainly realized by the deformation of the outer buffering ring 62 concentrated on the supporting ring bodies 62b at the two sides and the deformation of the inner buffering ring 61 concentrated on the edges at the two sides, the fluctuation of the first bearing 1 is alleviated by the deformation, thereby improving the stability of the operation, under the condition of stable product quality, the probability of the micro fluctuation of the first bearing 1 is higher, therefore, the high-frequency buffering with more sensitivity can be realized by the small range concentration of the deformation, the two sides of the inner ring 61a and the side wall of the first installation groove 31 are arranged at intervals, and the side surface 62b1 of the supporting ring body 62b and the side wall of the first installation groove 31 are arranged at intervals to reduce the friction force, so that the sensitivity is ensured.
Of course, the annular flange 61b and the inner ring 61a are relatively pressed during the damping process, but since there is no initial pressing therebetween, the force for supporting the first bearing 1 generated during the wave motion is negligible.
Secondary buffering: the purpose of buffering in a large range when the first bearing 1 collides with the internal gear 3 is to alleviate the hard impact between the first bearing 1 and the internal gear 3, and the purpose is realized by large deformation extrusion between each annular convex edge 61b and the outer ring body 62a, and the two-stage buffering mode is matched with the buffering mode in the one-stage buffering, so that the collision between the first bearing 1 and the internal gear 3 is flexible, the noise generation and the large fluctuation of the structure are effectively reduced, and the fluctuation generation probability is small, so that even though the deformation recovery sensitivity of multiple parts is low, the one-stage buffering is not greatly influenced.
In the secondary damping process, in addition to the radial fluctuation, the axial fluctuation inevitably occurs due to the large vibration, and in the above embodiment, the buffer of the first bearing 1 in the axial direction can also be achieved simultaneously by the annular flanges 61b being arranged at intervals from the two support ring bodies 62b, with the roots fixed and the ends free, as shown in fig. 8, the axial damping may be provided by play of the inner ring 61a relative to the outer damping ring 62, and the slight bending of the annular convex edge 61b, the invention selects the separately arranged inner and outer buffer rings, so that in the axial buffer process, the influence of the structural stability of the radial damping is reduced because of the change in the relative position of the two in this direction, i.e. excessive changes in shape in one direction caused by the material being stretched in the other direction are avoided.
EXAMPLE III

In the present embodiment, the method for mounting the planet carrier 2 in the first embodiment is adopted, but this method only alleviates the fluctuation transmitted to the outside of the planet carrier 2, and the fluctuation is necessarily transmitted to the axial direction, so that the fluctuation may be brought to the relative position relationship between the planet wheel 4 and the shaft body 5, in order to solve the above problem, the planetary reducer is further optimized in the present embodiment, the original mounting method of the second bearing 7 at the end of the shaft body 5 is changed, and the second bearing 7 can be buffered in the radial direction through the arrangement of the elastic buffer ring 6.
