Summary of the invention
The utility model purpose is to provide a kind of manufacturing cost lower, planetary gear reduction box that the transmission noise is less and reducing motor thereof, problem such as it is higher to have solved the manufacturing cost that existing planetary gear reduction box exists, and the transmission noise is bigger.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise the ring gear as casing, the front end housing of ring gear output and be positioned at the rear end cap of ring gear input, be used to accept the one-level sun gear of input torque near the rear end cap setting, the output shaft swivel bearing that is used for output torque is in front end housing, the final stage planetary gear is hollow shaft with the output shaft, the planetary gear and the sun gear transmissions that are arranged alternately by some levels between one-level sun gear and final stage planetary gear cooperate, sun gears at different levels and later planetary gear at different levels after the intensity of described one-level sun gear transmission intensity and the one-level planetary gear that meshes with the one-level sun gear is weaker than respectively.Because sun gears at different levels and planetary gear at different levels suffered moment of torsion in transmission process have nothing in common with each other, from the one-level planetary gear promptly at a high speed a level planet to take turns to the final stage planetary gear be that the suffered moment of torsion of slow speed turbine stage planetary gear increases gradually, it is one-level planetary gear suffered moment of torsion minimum in planetary gears at different levels, in like manner, one-level sun gear suffered moment of torsion in sun gears at different levels is also minimum, therefore, the utility model is arranged to the more weak gear of intensity with one-level sun gear and one-level planetary gear, and more weak its manufacturing cost of gear of intensity is lower usually, so guaranteeing that the utility model can effectively reduce the manufacturing cost of planetary gear reduction box under the situation that transfer torque needs; Simultaneously, more weak its quality of gear of intensity is also softer, so more weak one-level sun gear of itself and intensity and one-level planetary gear also can reduce the noise in the utility model transmission process.
As preferably, described one-level sun gear and one-level planetary gear are made by plastics, described after sun gears at different levels and later planetary gear at different levels all adopt metal gear.When one-level sun gear and one-level planetary gear adopt plastics to be formed in to reduce the utility model and make cost and transmission noise, also can alleviate overall weight of the present utility model; The metal gear that adopts later planetary gear at different levels then can satisfy them and bear needs than high pulling torque.
As preferably, described after the number of planetary gears at different levels take turns to the final stage planetary gear from secondary planet and increase gradually, the number of described secondary planet wheel equates with the number of one-level planetary gear.Wherein, the number by planetary gears at different levels after increasing gradually can improve the stationarity of transmission.
As preferably, cooperate by one-level planetary gear, secondary sun gear, secondary planet wheel, three grades of sun gear transmissions successively between described one-level sun gear and the final stage planetary gear, described one-level planetary gear is made up of three plastic gears, described secondary planet wheel is made up of three metal gear, and described final stage planetary gear is made up of four metal gear.Wherein, one-level planetary gear and one-level planetary gear adopt the plastics plastics to make when guaranteeing transmission intensity, have alleviated the noise in the transmission process; Secondary, three grades of sun gears and secondary, third-level planetary wheel adopt metal gear then can guarantee the intensity of transmission; The secondary planet wheel adopts three metal gear third-level planetary wheels to adopt four metal gear then can improve the stationarity of transmission in addition.
As preferably, described output shaft the inner is formed with the final stage planet carrier of one with it, and the wheel shaft of described final stage planetary gear and final stage planet carrier are fixed.Wherein, final stage planetary wheel carrier and output shaft are designed to integrative-structure, can further improve the stationarity of the utility model transmission.
The reducing motor that comprises the utility model planetary gear reduction box, motor shaft cooperates with the transmission of described one-level sun gear.
Therefore, it is lower to the utlity model has manufacturing cost, characteristics such as the transmission noise is less.
