Abstract
The utility model provides a compact type decelerator with large deceleration ratio, which comprises a casing and a decelerating mechanism mounted in the casing, wherein the decelerating mechanism consists of a planetary gear mechanism, a worm wheel and worm mechanism, and a gear mechanism; output shaft of the planetary gear mechanism is coaxial to the worm; the worm wheel fits the worm and is provided with a coaxial gear engaging into a large gear; gears coaxial to the large gear engage into the gear fixed on the output shaft. The utility model realizes the deceleration with the cooperation of the planetary gear mechanism, the worm wheel and worm mechanism, and the gear mechanism, gaining large deceleration ratio and rendering the general volume of the decelerator with small size as well as compact and simple structure and thereby lowering the manufacture cost and facilitating the decelerator mounting.
Description
(1) technical field
The utility model relates to a kind of retarder.
(2) background technique
Between dynamic power machines such as motor, petrol engine, diesel engine and action actuating mechanism, speed reducer to be set usually, make the purpose of action actuating mechanism to reach with suitable speed motion, speed reducer of a great variety, the speed reducer of different structure can meet the different needs.
(3) summary of the invention
The purpose of this utility model is to provide a kind of compact structure, reduction speed ratio is big, fabricating cost is low compact type big retarding ratio speed reducer.
The purpose of this utility model is achieved in that it comprises housing and is installed in the interior reducing gear of housing, described reducing gear comprises planetary gears, worm-and-wheel gear and gear mechanism, the output shaft of planetary gears is coaxial with worm screw, worm gear matches with worm screw, in-line gears are installed on the worm gear and this gear is meshed with gearwheel, with fixing gear engagement on coaxial gear of gearwheel and the output shaft.Described planetary gears comprises the two-stage planet reducing gear.
The utility model cooperatively interacts by planetary gears, worm-and-wheel gear and gear mechanism, reach the deceleration purpose, by this combination, reach bigger reduction speed ratio, make the overall volume of speed reducer little, compact structure, simple, thus fabricating cost reduced, and make installing and using of speed reducer more convenient.
(4) description of drawings
Accompanying drawing is a structural representation of the present utility model.
(5) embodiment
For a more detailed description to the utility model for example below in conjunction with accompanying drawing:
The composition of compact type big retarding ratio speed reducer comprises housing 1 and is installed in the interior reducing gear of housing.Reducing gear comprises planetary gears 2, the worm-and-wheel gear of being made up of worm gear 3, worm screw 4 and by with the coaxial gear 5 of worm gear, gearwheel 6, with the coaxial gear 7 of gearwheel be fixed on the gear mechanism that the gear 9 on the output shaft 8 is formed.The output shaft of planetary gears is coaxial with worm screw, and worm gear matches with worm screw, is fixed with in-line gears on the worm gear, is meshed with gearwheel with the coaxial gear of worm screw, with fixing gear engagement on coaxial gear of gearwheel and the output shaft.The output of power mechanism is input to planetary gear reducing mechanism, further slows down at the input turbine and worm decelerator behind planetary gear speed-reduction, reaches required rotating speed in the deceleration by reduction gears mechanism at last, is exported by output shaft.
Claims (2)
1, a kind of compact type big retarding ratio speed reducer, it comprises housing and is installed in the interior reducing gear of housing, it is characterized in that: described reducing gear comprises planetary gears, worm-and-wheel gear and gear mechanism, the output shaft of planetary gears is coaxial with worm screw, worm gear matches with worm screw, be fixed with in-line gears on the worm gear and this gear is meshed with gearwheel, with fixing gear engagement on coaxial gear of gearwheel and the output shaft.
