Motor with turbine and worm decelerator

Abstract

This invention relates to a kind of electric motor equiped with worm and worm-gear reducer which composed of an elecric motor and a worm / worm-gear reducing mechanism. The pivot of electric motor and worm of the reduce are combined into a single one. On the outer ends of said pivot and worm are equipped, respectively, bearings. It is characterised by that the diameter of the worm is 1.5 times of the diameter of pivot of electric motor. The other end near the pivot is equipped with another bearing. This invention electric motor is compacted with its size while gives out greater output force moment, which increased rigidity and stability and lowered noise and vibration.

Description

technical field [0001] The invention belongs to a small motor with a worm gear reduction mechanism. Background technique [0002] In a traditional small motor with a worm gear reduction mechanism, the shaft of the fixed armature is coaxial with the worm of the worm gear reduction mechanism connected to its transmission, and the diameter of the armature shaft is basically the same as that of the worm, so that both There is a contradiction between mutual containment: the overall diameter of the rod shaft is large, that is to say, when the diameters of the worm and the armature shaft are large, although the large diameter of the worm can increase the contact area between the worm and the worm wheel, increase the output torque and the worm wheel. service life, but the corresponding armature shaft diameter is also larger at this time, resulting in a corresponding increase in the diameter of the armature plate and commutator, thereby increasing the volume of the motor.

[0002] In a traditional small motor with a worm gear reduction mechanism, the shaft of the fixed armature is coaxial with the worm of the worm gear reduction mechanism connected to its transmission, and the diameter of the armature shaft is basically the same as the diameter of the worm, so that both There is a contradiction between mutual containment: when the diameter of the overall shaft is large, that is to say, when the diameters of the worm and the armature shaft are large, although the diameter of the worm is large, the contact area between the worm and the worm wheel can be increased, and the output torque and the worm gear can be increased. service life, but the corresponding armature shaft diameter is also larger at this time, resulting in a corresponding increase in the diameter of the armature plate and commutator, thereby increasing the volume of the motor

Conversely, if the diameter of the overall rod shaft is reduced, the diameter of the armature will be reduced, and the diameter of the worm will be reduced accordingly, which will affect the output torque and life of the worm gear reduction mechanism.

Moreover, the armature worm shaft of this overall structure is only at its two ends: that is, the outer end of the armature shaft and the outer end of the worm shaft are provided with support bearings, and there is no supporting point in the middle of the integral rod shaft, so the rigidity and rotation of the motor are affected.
