Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
As shown in Figure 1 and Figure 2, a kind of planetary reducer with deformation gear ring structure, including it is procapsid 1, back casing 5, defeated
Shaft 3, rack gear 4 is arranged at the assembly of procapsid 1 and back casing 5, and gear ring 4 uses flexible deformable thin-walled gear ring, procapsid
1, back casing 5, gear ring 4 are connected as one by screw 8, and there are assembly with the place of docking of procapsid 1, back casing 5 for gear ring 4
Gap, as shown in figure 3, the face A, the face B, the face C as shown in Figure 4, assemble the gap in gap using same size, the wall thickness of gear ring 4
For 3mm-20mm.
Gear ring 4 is processed relatively thin, and it is alloy steel that the material of gear ring, which is 35CrMo, and the deformation coefficient of gear ring is 0.05-
0.25, change the flexibility of gear ring.Gear ring and procapsid 1 are convenient for assembly and disassembly, together there are assembly gap when back casing 5 assembles
When it is impaired when preventing matched components from dismounting.Because there are the assembly faces gap C at gear ring 4 and 5 cooperation of back casing, so dress
Timing convenient for assembly, work at the same time it is middle because planetary gear 6 rotate bring error can play the role of elimination, make to make an uproar when work
Sound, transmission accuracy are more preferable.
In addition, output shaft 3 connects the mandrel 9 of planetary gear 6, the both ends of the surface of planetary gear 6 are socketed with wear-resistant pad 7, row
The radial outside of star gear 6 is engaged in gear ring 4, and the radially inner side of planetary gear 6 is engaged in sun gear 10, and sun gear 10 connects
Input shaft 11 is connect, input shaft 11 is socketed big gasket 17 close to 10 end face of sun gear, and the surface of output shaft 11 offers screw hole, greatly
Gasket 17 is anchored on the screw hole on 3 surface of output shaft by screw, and the surface of output shaft 3 is socketed with duplex bearing 2, the diameter of duplex bearing 2
Support force is provided by procapsid 1 outward, the surface of input shaft 11 is socketed with single-bearing 12, and the radial outside of single-bearing 12 is by rear
Shell 5 provides support force.
Gear ring 4, planetary gear 6, sun gear 10 are all made of high gear tooth-shape structure.Input shaft 11, sun gear 10,
The axle center of output shaft 3 is in same straight line.
Input shaft transfers power to sun gear, and input shaft drives sun gear rotation, and sun gear engages planet tooth
Wheel, planetary gear are three, and gear ring is engaged in planetary gear outer ring, because of ring gear machining sShape features, are cooperated with other components
When, it can achieve elimination mismachining tolerance, rigging error.Because of ring gear machining shape, gear ring is thinning, increases the toughness of gear ring.Tooth
Circle processing shape effect, when assembly, are easily installed disassembly.There are space when cooperating when assembly, can become in the gear ring course of work
The problem of shape, can eliminate mismachining tolerance, rigging error.The precision of speed reducer is improved, noise is reduced, exports axis connection planet tooth
The mandrel of wheel, mandrel drive output shaft rotation, and output shaft outputs power, and complete deceleration, and assembly can achieve when cooperating
The effect of error is eliminated, is convenient for assembly and disassembly, while preventing the damage of other parts.
