Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of speed reducer, particularly a kind of worm reduction gear.
Background technique
The structure of present worm reduction gear generally all is such, a kind of (application number: 200410074746.3) of motor with turbine and worm decelerator is disclosed as Chinese patent, be provided with motor, turbine and worm decelerator, the armature shaft of motor is one with coaxial being in transmission connection of the worm screw of turbine and worm decelerator, the armature shaft outer end and the worm screw outer end that are positioned on the same axis are equipped with block bearing and block bearing respectively, described worm screw diameter is 1.5～6 times of armature shaft diameter, and worm screw is equipped with block bearing at its end near armature shaft.There are the following problems for the motor of said structure: because the existence of turbine and worm decelerator, in the process of motor rotation, the axial force that rotor shaft is subjected to is bigger, easily cause moving axially between rotor shaft and the end cap, it is even more serious when reducing gear connects bigger load, this mobile ride quality that will have a strong impact on motor, even may cause scrapping of motor.
The model utility content
The purpose of this utility model is to have above-mentioned problem at existing worm reduction gear, provides that a kind of structure is simpler, the worm reduction gear of longer service life, deceleration better effects if.
The purpose of this utility model can realize by following technical proposal: a kind of worm reduction gear, comprise a housing, it is characterized in that, also be provided with motor, worm gear and worm screw in the described housing, described worm and wheel is meshed, and an end and the motor of worm screw link, and also are arranged with the rotating shaft that an energy and wheel hub link in worm gear.
This worm reduction gear is used for slowing down, and can be applied on the tire etc. of belt, automobile.The working principle of this worm reduction gear is such, the rotation of motor drives the rotation of worm screw, the rotation of worm screw drives the rotation of worm gear again, and the rotation of worm gear drives the rotation of the rotating shaft that links with it again, and rotating shaft makes in the deceleration of the belt that links with it or tire again.
In above-mentioned worm reduction gear, also be provided with a shoe cream room between the described worm and wheel, have a filler opening that passes housing on the described shoe cream room.By the oil in the shoe cream room worm and gear is lubricated, makes the transmission better effects if.
In above-mentioned worm reduction gear, described rotating shaft outer end also is provided with end cap, and described end cap is fixed together by bolt and housing.By end cap rotating shaft is covered and to prevent that dust from entering in the housing.
In above-mentioned worm reduction gear, also be arranged with bearing in the described rotating shaft.By bearing rotating shaft is fixed.
In above-mentioned worm reduction gear, also be provided with Sealing between described rotating shaft and the housing.By between rotating shaft and the housing Sealing being set, make the better tightness between rotating shaft and the housing.
Compared with prior art, this worm reduction gear has the following advantages:
1, this worm reduction gear is used as speed reducer by worm and gear, simple in structure, slow down effective.
2, this worm reduction gear has a shoe cream room, by the oil in the shoe cream room worm and gear is lubricated, and makes the longer service life of this worm reduction gear.
3, the rotating shaft outer end of this worm reduction gear has an end cap, by end cap rotating shaft is covered and prevents that dust from entering in the housing.
