Description
Technical field
The utility model relates to a kind of speed reducer, especially relates to the stockbreeding machine speed reducer of a kind of motor flange band bearing location.
Background technique
Reducing motor is a kind of actuating unit, mainly utilizes gear to carry out rate conversion, the output winding number of motor shaft is decelerated to required winding number, just obtains the device of larger torque.Chinese patent discloses the power plant (Authorization Notice No.: CN 202575293 U) for feed conveying machine, on its motor output shaft, fixed cover is equipped with coupling, coupling is by a bearing (only having a bearing) speed reducer inwall location relatively, coupling front end is nested arranges tooth axle, and the reduction gear that tooth beam warp one engages with tooth axle drives pto＝power take-off.Because coupling and speed reducer inwall are only supported by a bearing, when output loads is unstable, the coupling that can affect on input gear is subject to fluctuating load impact, is easy to the bearing wear of this coupling of supporting is killed, affects normal transmission.
Model utility content
The utility model is to provide the stockbreeding machine speed reducer of a kind of motor flange band bearing location, it mainly solves only being supported by a bearing due to coupling and speed reducer inwall existing for prior art, when output loads is unstable, the coupling that can affect on input gear is subject to fluctuating load impact, be easy to the bearing wear of this coupling of supporting is killed, affect the technical problem of normal transmission etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The stockbreeding machine speed reducer of a kind of motor flange band bearing location of the present utility model, comprise casing, described tank ends is respectively equipped with input flange, output flange, input flange place is provided with input gear axle, the external part of input gear axle the inner is engaged with driven gear, driven gear is fixed with output shaft, output shaft outer end is stretched out outside output flange, input gear axle is provided with step, the first bearing of input shaft is respectively equipped with between the input gear axle outer surface of the both sides of step and the inwall of casing, second bearing of input shaft, input shaft oil seal is provided with between input gear axle outer end and input flange, O-ring seals is provided with between casing and input flange.Input gear axle, by the first bearing of input shaft, the second bearing of input shaft, gives dual supporting relative to cabinet wall, thus ensures that input gear axle is operably comparatively stable.On the left of input gear axle, bearing external part is gear structure, and this gear engages with driven gear, transferring power; Be band keyway endoporus in the right side of input gear axle, this endoporus coordinates with input motor shaft, and connects transmitting torque by keyway.Driven gear is fixed on output shaft by key, is inputted and drive output shaft rotation, outputting power after engaging with driven gear by input gear axle.Input shaft oil seal, O-ring seals can avoid the pollution of lubricant oil to working environment of seepage, have also stopped speed reducer and have lost oil and cause gear wear.
As preferably, the first output shaft bearing, the second output shaft bearing is respectively equipped with between the output shaft of described driven gear both sides and casing, output shaft oil sealing is provided with between in the middle part of casing and output shaft, the both sides of the first output shaft bearing are respectively equipped with hole back-up ring, shaft block ring, and the casing of output shaft the inner is provided with oil seal cover.Oil seal cover can facilitate the demolition of output shaft under the effect of external force by instrument after taking out.Output shaft oil sealing can prevent oil seepage.
As preferably, described casing top is fixed with case lid by sunk screw, is provided with case lid sealing gasket between case lid and casing.Opening case lid can so that the dismounting of speed reducer inner components.
Therefore, the utility model installs the first bearing of input shaft, the second bearing of input shaft respectively additional on input gear axle, the effect of double supporting can be played input gear axle, thus prevent the coupling on input gear to be subject to fluctuating load impact, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: casing 1, input flange 2, output flange 3, input gear axle 4, driven gear 5, output shaft 6, first bearing of input shaft 7, second bearing of input shaft 8, first output shaft bearing 9, second output shaft bearing 10, output shaft oil sealing 11, hole back-up ring 12, shaft block ring 13, oil seal cover 14, input shaft oil seal 15, O-ring seals 16, sunk screw 17, case lid 18, case lid sealing gasket 19.
