Abstract
The utility model relates to a worm and worm gear speed reducing motor for opening and closing an automobile skylight. A worm is mounted on a rotary shaft of a direct-current motor used as a power source, power is transmitted to a worm gear by the worm in a variable direction manner, the worm gear is connected with a transmission gear by a spring spline, the transmission gear is connected with an output gear in a meshed manner, a bevel gear is assembled at an output end of an output gear shaft, and the worm gear and the transmission gear are arranged in a split manner. The worm and worm gear speed reducing motor is reasonable in structure, reliable in performance, high in transmission efficiency and low in noise, a temperature and current automatic heat dissipating integral protector is further mounted inside the motor, can automatically dissipate heat and cut off a power supply to protect the motor against being burned under conditions of excessively high temperature of an operating environment or over-current, a plastic inductive magnetic ring is further mounted on the motor shaft to bring convenience for rotation speed detection, and the worm and worm gear speed reducing motor can act by manually pressing down the spline when the power source of the motor is blocked due to the fact that the worm gear and the transmission gear are split and connected with each other by the spring spline.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of worm and wormwheel reducing motor that is used for the switch vehicle dormer window.
Background technology
Reducing motor is a kind of power drive mechanism, utilizes the velocity transducer of gear, the winding number of motor is decelerated to desired winding number, and obtain bigger torque, is being used for the mechanism of transferring power and motion at present, and the application of reducing motor is quite extensive.
The worm decelerating machine transmission efficiency is low, the gear-driven efficiency height, and when the certain speed reducing ratio of power was very big, the gear drive meeting was bigger than worm-drive volume, can solve the problem that volume is excessive, transmission efficiency is low excessively with gear and worm screw combination.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple in structure, technology is reasonable, noise is little, power output is big worm and wormwheel reducing motor that is used for the switch vehicle dormer window is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of worm and wormwheel reducing motor that is used for the switch vehicle dormer window, on dc motor shaft, worm screw is installed as power source, give worm gear by worm screw break-in transmission, worm gear is connected with travelling gear by spring spline, travelling gear and output gear are connected with a joggle, and output is fitted with helical gear on the output gear shaft, and worm gear and travelling gear are the split setting
According to another embodiment of the present utility model, a kind of worm and wormwheel reducing motor that is used for the switch vehicle dormer window further comprises: described motor internal is equipped with temperature and overcurrent spontaneous heating integrated protective device near an end of rotating shaft.
According to another embodiment of the present utility model, a kind of worm and wormwheel reducing motor that is used for the switch vehicle dormer window further comprises: in the rotating shaft of described motor reaction magnetic ring is installed.
The utility model has solved the defective that exists in the background technology, and its beneficial effect is: compact conformation, and gearratio is big, and technology is reasonable, and noise is little, and power output is big; The spontaneous heating protector is equipped with in inside, occurs behind the overcurrent oneself heating cutting off the electricity supply, and the protection motor is not burnt out; Plastics magnet ring with induction effect is housed, the convenient rotating speed that detects in the rotating shaft of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the stereochemical structure broken away view of preferred embodiment of the present utility model;
Wherein: 1, motor, 10, rotating shaft, 11, commutator, 17, protector, 19, the plastics magnet ring, 20, worm screw, 22, deceleration box, 27, output gear, 29, helical gear, 31, travelling gear, 33, spring spline, 34, worm gear, 36, gear box cover.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As depicted in figs. 1 and 2, the center of the utility model reducing motor 1 is equipped with rotating shaft 10, worm screw 20 is installed in the rotating shaft 10 to insert in the reduction box and worm gear 34 engagements, worm gear 34 is installed in the center of a cavity of deceleration box 22 and gear box cover 36 compositions, on the same axle of worm gear 34, travelling gear 31 is installed also, worm gear 34 is connected by spring spline 33 between the two with travelling gear 31, travelling gear 31 is connected with a joggle with helical gear 29, and helical gear 29 and output gear 27 all are connected on the same axis by spline; Motor 1 an inner end near rotating shaft 10 also is equipped with spontaneous heating protector 17, can oneself generate heat to cutting off the electricity supply behind overcurrent and protect motor 1 not burnt out; In the rotating shaft 10 of motor 1 plastics magnet ring 19 is installed also, it has induction effect, the convenient rotating speed that detects.
The course of work of the present utility model is: motor 1 drives rotating shaft 10 and worm screw 20 is rotated simultaneously, and worm screw 20 is given worm gear 34 by engagement with power transmission, thereby finishes the bigger deceleration of gearratio; Worm gear 34 is given coaxial travelling gear 31 by worm-wheel shaft with transmission of power, and travelling gear 31 is given helical gear 29 by engagement with transmission of power, thereby finishes the change of direction and deceleration once more; Thereby helical gear 29 transmission of power the most at last outputs power for coaxial output gear 27.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
