Description
Technical field
The utility model relates to a kind of automobile component, relates in particular to the skylight motor on the automobile.
Background technology
The skylight motor is the vitals on the automobiles such as car, heavy goods vehicles, for the motion in skylight provides power.Existing vehicle dormer window motor is made of electric machine casing, rotor, stator, armature shaft, decelerator and major axis, and the armature shaft of motor is connected with the input of decelerator, and the output of decelerator is connected with major axis, suit transmission arm on major axis.When the positive and negative rotation of the armature shaft of motor, decelerator is accepted the power of motor, and drives opener and transmission arm by major axis, and the skylight is opened or closed.Owing to spatially intersect between armature shaft and the major axis, mechanism's complexity of whole motor, assembling difficulty, Heavy Weight, the volume that takes up room are bigger; Simultaneously, wear-resisting, the corrosion-resistant of running part, useful life is short, and vibration is bigger in transmission, and the transmission noise is higher.
The utility model content
The vehicle dormer window motor that technical problem to be solved in the utility model is to provide a kind of compact conformation, the volume that takes up room is little.
The technical solution of the utility model is as follows: a kind of vehicle dormer window motor, comprise electric machine casing, rotor, stator, armature shaft, reducer shell and major axis, wherein electric machine casing and reducer shell fix, rotor and stator are installed in electric machine casing, be connected with armature shaft on the rotor, its key is: the end of described armature shaft is designed to worm screw, this worm screw stretches in the reducer shell, and be meshed with gear on worm, described gear on worm is set in an end of small worm, this small worm and armature shaft are perpendicular, the worm screw end of small worm and worm gear engagement, this worm gear set is contained on the major axis, and oppositely stretch out from the both ends of the surface of reducer shell at the two ends of major axis, and major axis is parallel to described armature shaft.
The utility model adopts the double reduction transmission, is cooperated by two groups of worm couples, to realize the change of the torque and the direction of motion.After the energising, armature shaft rotates under the electromagnetic force effect, and drives gear on worm and small worm rotation, realizes the one-level deceleration transmission of 90 ° of crossed axis angles; In the time of the small worm rotation, drive the rotation of worm gear and major axis, realize the double reduction transmission of 90 ° of crossed axis angles, satisfied requirement skylight motor torque and rotating speed.Because major axis is parallel to described armature shaft, whole apparatus structure compactness, in light weight, the volume that takes up room is little, in convenient assembling fast, can effectively reduce production costs.
Described gear on worm is a moulding, and is injection-moulded on the steel small worm; Described worm gear is a moulding also, and worm gear is injection-moulded on the major axis.Above structure can further alleviate the weight of motor, not only wear-resisting, good corrosion resistance, and long service life, and also vibration is little in transmission, and the transmission noise is very low.
The helical angle of worm screw is 13 degree on the described armature shaft, and the helical angle of described small worm is 6 degree, and not self-locking of first-stage worm gear worm mechanism like this, and the self-locking of second-stage worm gear worm mechanism can be guaranteed the flexibility and the reliability of transmission.
Beneficial effect: the utility model belongs to the low rotation speed large torque transmission, satisfied requirement to skylight motor torque and rotating speed, have that reasonable in design, compact conformation, assembling are easy, in light weight, wear resistant corrosion resistant, characteristics such as vibration is little, the transmission noise is low, long service life, production cost are low, help producing fast in enormous quantities.
Description of drawings
