The speed reduction motor has the advantages of compact structure, convenient mounting or dismounting and assembly, large range of transmitting ratio and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of reducing motor.
Background technology
At present, the reducing motor of selling on the market or in life, in the factory and enterprise, use, it is formed by connecting by reduction gear box and motor.This connected mode is exactly to be fastened on the rear end cap of reduction gear box by the front end housing of bolt with motor.During work, the power output shaft of motor rotates, because the power output shaft of the motor gear reduction interior with being arranged on gear reduction box is connected, and the running of driven gear reducing gear, thus realized the purpose of slowing down.
But being connected between the one-level travelling gear in the power output shaft of this reducing motor and the gear reduction is for axle key is connected.Because this axle key cooperates and links generally all is interference fit, thereby mounting or dismounting are relatively more difficult, and assembling is inconvenience also; And owing to be that axle key cooperates binding, add axis hole and keyway on the one-level travelling gear, this just requires travelling gear must have enough big external diameter.The change of external diameter means increasing of the one-level travelling gear number of teeth greatly, because the gearratio between one-level travelling gear and the secondary travelling gear is the inverse ratio of their numbers of teeth, the number of teeth of secondary travelling gear is constant, so gear ratio is just less, this has just restricted range of transmission ratio.
Summary of the invention
The purpose of this utility model is at the above-mentioned problem that exists in the prior art, and a kind of easy to loading and unloading, reducing motor that gear range is big is provided.
The purpose of this utility model can realize by following technical proposal: a kind of reducing motor, comprise motor and the reduction gear casing that is connected with motor, in reduction gear casing, be provided with gear reduction, be provided with rotor and motor output shaft in the motor, it is characterized in that described motor output shaft end has profile of tooth and this end is meshed with gear reduction.
During energising, motor comes into operation, and rotor and motor output shaft begin to rotate, and the direct driven gear reducing gear running of motor output shaft makes last output speed reach requirement.
In above-mentioned a kind of reducing motor, described gear reduction comprises gear shaft and the output shaft that is arranged on the reduction gear casing, gear shaft cooperates by axle key and is connected with the one-level gear, and gear shaft is provided with profile of tooth and is meshed with secondary gear, secondary gear cooperates by axle key and is connected with output shaft, and above-mentioned one-level gear is meshed with the profile of tooth end of motor output shaft.
During reducing motor work, the rotation of motor output shaft is rotated one-level gear and gear shaft synchronously, and then gear shaft drives the secondary gear rotation, and last secondary gear drives the rotation of output shaft.
In above-mentioned a kind of reducing motor, described one-level gear and secondary gear are helical gear.Stability when helical gear has guaranteed one-level gear and secondary gear running.
In above-mentioned a kind of reducing motor, be equipped with bearing between described gear shaft and output shaft and the reduction gear casing.Bearing supporting gear axle and output shaft have reduced the friction of gear shaft and output shaft, have increased useful life.
In above-mentioned a kind of reducing motor, described bearing and reduction gear casing inwall directly are provided with packing ring.Packing ring has cushioned the collision between bearing and the gear box body, makes reducing gear stable.
In above-mentioned reducing motor, be provided with sealing ring between the inwall of described reduction gear casing and the motor output shaft.Sealing ring prevents that the oil in the reduction gear casing from infiltrating motor, makes the motor security of operation stable.
In above-mentioned reducing motor, the bottom of described reduction gear casing is provided with installation foot.Installation foot makes reducing motor convenient and reliable when mounted.
Compared with prior art, the motor output shaft of this reducing motor is meshed with one-level gear in the gear reduction, cancelled motor output shaft in the past and cooperated with axle key between the gear reduction, motor and gear reduction is easy to loading and unloading like this, mechanism's compactness.And eliminated axle key and cooperate the problem of bringing that can increase about the one-level outside diameter of gear, so the gear range of this reducing motor is big.
