The machine is composed of a flanged motor, a reducer casing, a machine base and a quincuncial elastic shaft coupling, wherein, an input and an output shafts of the reducer casing are arranged at the side, and are vertically downwards; the flanged motor shaft is upward connected with the input shaft by using the quincuncial elastic shaft coupling; motor flanges and a casing body are connected and reversely suspended on the reducer casing by using bolts and are parallel to the output shaft; the reducer casing and the machine base are separate. The utility model has the advantages of height of the complete machine reduction, part size decrease, easy processing, convenient installation and centering and low noise, and can be used for machinery of chemical industries, medicine, non-ferrous metallurgy, coal and mine.

Description

Flanged motor is hung by the feet and is hung parallel installation, split type vertical type speed reducer (change gear)

The utility model is a kind of deceleration machinery, particularly a kind of chemical industry, medical automatic reaction jar and nonferrous metallurgy, coal, supporting speed reducer of using of mining machinery of being exclusively used in.

Domestic existing chemical industry, medical automatic reaction jar and nonferrous metallurgy, coal, mine industry all are cycloidal planetary gear speed reducers with coal washer, the matched speed reducer of stirrer, add the whole (see figure 1) that a support is formed again.This type is the boundary dimension extra-high-speed not only, and is also extremely inconvenient to whole machine installation and transportation; And because the size height, it is big to take up space, the factory building height also corresponding increasing, increased the workshop building cost.This kind type is continued to use decades at home, and big improvement is not arranged always.

Task of the present utility model is that a kind of flanged (FLGD) motor of design is hung the parallel installation of extension by the feet, and speed reducer and support make split type, adopt the speed reducer of plum blossom elastic coupling flexible coupling, to lower the complete machine height, dwindle external dimension, convenient installation, centering, reduce noise, be convenient to manufacturing.

The contrast accompanying drawing elaborates to the utility model:

Wherein: accompanying drawing 1 is outside domestic chemical industry, the matching used speed reducer of medical automatic reaction jar

Type figure.

Accompanying drawing 2 is structural representations of the present utility model.

Accompanying drawing 3 is that the K of accompanying drawing 2 is to view.

Accompanying drawing 4 is fundamental diagrams of the present utility model.

The reductor of making according to the utility model is such as Fig. 2, shown in Figure 4. This machine is by the band method Blue motor (1) reduction box (2), support (3), plum blossom yielding coupling (4) form. (5) be to subtract Speed case output shaft, (6) are that motor flange, (7) are reduction box input shafts. This machine reduction box (2) Power shaft and output shaft do at homonymy, and vertically downward, diaxon stretches out on place's casing and is processed with Two inner stoppers, the axle of flanged motor (1) vertically upward, this axle and reduction box input shaft (7) Connect with plum blossom yielding coupling (4), and end on the male half coupling on the motor flange and the casing Mouth cooperates, the location, and fixes with nut, and motor (1) upset hanging is installed on the reduction box, Parallel with reduction gearbox output shaft (5), lower significantly the complete machine height; For reduce accessory size, Facility is processed respectively, and reduction box (2) and support (3) make split type, and support (3) is installed in and subtracts Speed case below, output shaft (5) passes support, becomes vertical installation. Support (3) is upper along end face, adds Worker's male half coupling cooperates with inner stopper on the reduction box, location, and fix with nut, lower edge with Institute's supporting machinery connects, and output shaft (5) connects with work mechanism. Power is by the parallel peace of upset hanging The motor of dress is passed to the power shaft of reduction box by the plum blossom yielding coupling, again through slowing down Case is inner to slow down, and passes on the output shaft, and downward outputting power drives chemical industry, medicine machinery again Retort or nonferrous metallurgy, coal, the coal washer of mine industry, mixer work. Slow down Be roller gear in the case, when speed reducing ratio is 4-20, adopt double reduction, when speed reducing ratio is 22.4-100 o'clock, adopt three grades of decelerations, two gear shaft centre-to-centre spacing A1=a3+a4, when slowing down for three grades, Three gear shaft centre-to-centre spacing A2=a1+a2+a3, as shown in Figure 3, input and output shaft centre-to-centre spacing A1=A2, tubeization casing specification is convenient to processing and manufacturing like this, like this at reduction box (2) size constancy Situation under, split type support (3) can be according to supporting needs, make difformity, no Unidimensional, enlarge the scope of application; Flanged motor (1) is used the plum blossom bullet with reduction box input shaft (7) The property shaft coupling (4) connect, be convenient to install, centering, back noise falls. Roller gear compares cycloidal pin Wheel gear rotational efficienty height.

The utility model has the advantages that and lower significantly the complete machine height, reduce accessory size, convenient Processing, make, be easy to install, centering, reduce noise, match power is big, applied widely, The transmission efficiency height.

Utilize 2,4 pairs of the utility model of accompanying drawing to be further described:

Shown in Fig. 2,4, A-A is the separating surface of speed reducer (2) and support (3), speed reducer (2) and motor flange (6), input shaft of speed reducer (7) and output shaft (5) are made the homonymy at the A-A face, on the A-A face, be processed with respectively and input shaft, two concentric inner stoppers of output shaft, on motor flange (6) and support (3) upper edge end face, also be processed with and motor shaft two outer stoppers that reduction gearbox output shaft is concentric respectively.After speed reducer requires to assemble according to drawing, A-A is faced down, be input shaft (7) and output shaft (5) vertically downward, again with motor (1) the axle vertically upward, this axle is with after input shaft (7) connects with plum blossom elastic coupling flexible coupling (4), with the outer stopper of motor flange (6), aims at that inner stopper on the deceleration box cooperates, the location, and use bolt, make motor (1) hang extension by the feet and be installed on the speed reducer.Support of split (3) and speed reducer (2) are also cooperated, are located by outer stopper on the end face of support upper edge and the inner stopper on the speed reducer, and constitute integral body with bolt.When power is imported into speed reducer input [high speed shaft] (7) by plum blossom elastic coupling flexible coupling (4) by motor (1) after, by gear-box two-stage or three grades of decelerations, pass on the reduction gearbox output shaft [lower velocity shaft] (5), pass to chemical industry, medical automatic reaction jar or nonferrous metallurgy, coal, mine etc. downwards mechanically by input shaft (5) again, drive the work mechanism operation.
