Description
Technical field
The utility model relates to a kind of integral type electricity and drives speed reducer.
Background technique
At present, speed reducer general on market and electric driving device are all splits, need to be connected by connecting plate, and installation process is complicated, the vibrations brought due to motor rotation in the running of motor can cause connecting screw easily to loosen, and the steadiness of tie point is poor, cause whole electric machine structure to loosen, the wearing and tearing between all parts can be strengthened, can motor damage be caused what is more.Greatly, take up room large, and produce very large noise, cost is high, and precision is low, the easy leakage of oil of words of mould assembling poor sealing, reduces mechanical life for speed reducer and electric driving device volume.
Model utility content
For solving the problem, the utility model provides a kind of integral type electricity and drives speed reducer, and this electricity drives speed reducer compact structure, volume is little, lightweight, transmission efficiency is high.
For implementing above-mentioned purpose, disclosed in the utility model, integral type electricity drives speed reducer, and it comprises electricity and drives speed reducer shell, and electricity drives side in speed reducer shell and is provided with electric driving device, and the opposite side that electricity drives in speed reducer shell is provided with planet gear reducing mechanism; The main shaft of electricity driving device is provided with starting gear; Planet gear reducing mechanism comprises internal tooth casing, planet wheel and planetary wheel carrier; Described planet wheel is arranged on described planetary wheel carrier side by bearing pin and bearing rotationally; The cylindrical of described electric driving device is provided with the raised line of bar shaped, described electricity drives the groove being provided with in speed reducer shell and coordinating with raised line, and by the cooperation between raised line and groove, electric driving device is inserted into electricity and drives in speed reducer shell.
Further, described bearing pin is vertically set on described planetary wheel carrier side, and described bearing housing is contained on described bearing pin, and described planet wheel is sleeved on bearing top circle.
Further, described planet gear reducing mechanism comprises some grades of planet wheels and planetary wheel carrier.
Further, described planet gear reducing mechanism comprises primary planet wheel, primary planet wheel carrier, secondary planet wheel and secondary planet wheel carrier.
Further, described primary planet wheel is arranged on primary planet wheel carrier one side rotationally by described bearing and bearing pin, and the another side of primary planet wheel carrier is provided with one-level sun gear; Primary planet wheel to be meshed with described starting gear transmission; Secondary planet wheel is arranged on secondary planet wheel carrier one side by described bearing pin and bearing, and the another side of secondary planet wheel carrier is provided with output shaft; Described secondary planet wheel is meshed with described one-level sun gear.
Further, described electricity drives speed reducer shell and output shaft one end is provided with cover plate, is provided with output bearing between cover plate and described output shaft.
Technique scheme of the present utility model has following beneficial effect: the utility model compact structure, without the need to connecting plate between electricity driving device and speed reducer, realize the integrated design of electric driving device and speed reducer, and cover plate and secondary planet take turns the organic combination of reducing gear, shake when making electricity drive speed reducer running and can not cause between sun gear and linkage structure, between linkage structure and electric driving device, wearing and tearing between linkage structure and internal tooth casing etc. between parts and collision, make overall structure more firm, reduce mechanical loss, extend the working life of machine, and the integrative design between parts, after effectively can making up the equipment prolonged exercise with linkage structure, integrally-built backhaul gap becomes large shortcoming, and the length of single unit system is shortened in the design of integration, reduce consumptive material, simplify structure, reduced volume, reduce manufacture cost, and owing to lacking middle screw connecting link, improve the stability of a system, more steady.
