Abstract
The utility model relates to a flange type stepless speed regulation vertical output speed reducer whose structure is that a motor and a stepless speed regulation device are connected directly and formed into the first stage deceleration. A pinion and a gear wheel that are fixed on the output shaft of the stepless speed regulation device fixed on the box body a speed reducer constitute the second stage deceleration. The gear wheel is installed fixedly on the shaft platform on one end of a worm rod, and the shaft platform on the middle part of the worm rod is provided with a supporting rotary bearing; a worm gear drives the worn rod to rotate, and the interior of the shaft hole of the worm gear is installed fixedly with a vertical output shaft. The output end of the speed reducer is also provided with a flange disk with a rabbet and an installation hole, and the positioning rabbet of the flange disk is concentric with the vertical output shaft; consequently, the connection between the speed reducer and the external equipments is easier and quicker, and the structure of the connection is more compact. According to the user's requirement, the vertical output shaft is served as the hollow structure and the solid structure; the speed reducer also has the advantage of higher stepless speed reducing ratio. The utility model can be used broad in the deceleration mechanism of various mechanical devices for the metallurgy, the mine, the hoisting, the light industry, the chemical industry, the transportation, the architecture, etc.
Description
Technical field
The utility model belongs to speed reducer, particularly relates to a kind of flange plate type stepless speed regulation vertical output speed reducer.
Background technique
At present, domestic known standard stepless speed regulation speed reducer mostly is the friction type speed change, and its speed adjustable range is less, generally only is 950～190 rev/mins, can not obtain bigger reduction speed ratio.Another kind of standard stepless speed-regulating device+cycloid speed reducer though can obtain bigger reduction speed ratio, all can only be same shaft drive generally, and the interval of speed ratio be bigger, also can't realize vertical transmission and quill drive.If adopt worm-gear speed reducer, though this can obtain vertical transmission, there is the big at interval shortcoming of speed ratio, can not realize direct connection with stepless speed-regulating device.If adopt the hardened face gear speed reducer, desire will seek out bigger reduction speed ratio, and therefore its transmission shaft must, certainly exist volume and increase more than three, the shortcoming that weight is also heavier than other speed reducer, and, can not carry out stepless time adjustment.
Summary of the invention
The utility model provides a kind of flange plate type stepless speed regulation vertical output speed reducer for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of flange plate type stepless speed regulation vertical output speed reducer, be made up of motor, stepless speed-regulating device, small gear, gearwheel, worm screw, worm gear, casing, output shaft, flange plate, bearing, flat key and fastening piece, it is characterized in that: the shaft of motor is by the be connected input hollow shaft of a stepless speed-regulating device of flat key; The blind flange of stepless speed-regulating device is connected by the casing of seam location and fastening piece and speed reducer; Small gear of the output shaft fixed connection of stepless speed-regulating device; Gearwheel of pinion; Gearwheel is packed on the pillow block of worm screw one end; Be equipped with on the middle part pillow block of worm screw and support the bearing that rotates, worm drive worm gear; Install a vertical output axle in the axis hole of worm gear; The output terminal of this speed reducer also is provided with the flange plate of band seam and mounting hole.
The utility model can also adopt following technical measures:
Described vertical output axle can be vertical hollow output shaft, also vertical solid output shaft.
Advantage and the good effect that the utlity model has are: the shaft of motor forms the first order and slows down by the input hollow shaft direct connection of flat key and stepless speed-regulating device, without coupling, makes structure very compact.Adopt the stepless speed-regulating device of standard herein, not only easy to assembly, but also can obtain bigger stepless reduction speed ratio, and forming the second level by small gear and gearwheel engagement simultaneously and slow down, worm screw drives worm drive, thereby forms the vertical output of speed reducer.According to user's needs, vertical output can be made hollow shaft, also can make solid shaft.This speed reducer also is provided with the flange plate of band seam and mounting hole, and the positioning spigot of flange plate is concentric with the vertical output axle, so it is convenient, quick that this speed reducer is connected with external equipment, structure is compact more.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the shaft of motor 1 is connected by the input hollow shaft of flat key and stepless speed-regulating device 2, and simultaneously, the blind flange of motor 1 is connected by the casing of bolt and stepless speed-regulating device 2.The blind flange of stepless speed-regulating device 2 is connected by the casing 6 of seam location and bolt and speed reducer; The small gear 4 and the output shaft 3 usefulness flat keys of these arrangements for speed regulation 2 are connected; Small gear is meshed with gearwheel 5; The axis hole of gearwheel 5 is packed in by flat key on the pillow block of worm screw 7 one ends, is equipped with on the middle part pillow block of worm screw 7 to support the thrust bearing that rotates, and worm screw 7 drives worm gear 8 and rotates, and the axis hole of worm gear 8 installs a vertical output axle 9; The output terminal of this speed reducer also is provided with the flange plate 10 of band seam and mounting hole in addition.The positioning spigot of flange plate 10 is concentric with vertical output axle 9, so it is convenient, quick that this speed reducer is connected with the installation of external equipment, its structure is compact more.
The vertical output axle 9 of this reductor can be vertical hollow output shaft, also vertical solid output shaft. This deceleration Machine can obtain bigger stepless speed reducing ratio, has the advantages such as compact conformation, easy for installation and vertical output axle, can be widely used in The reducing gear of the various plant equipment such as metallurgy, mine, lifting, light industry, chemical industry, transportation and building.
