Description
Technical field
The utility model relates to a kind of improvement invention of vertical type speed reducer (change gear).
Background technique
Vertical type speed reducer (change gear) is gained the name because when work wants vertical installation, vertical type speed reducer (change gear) is often used in some and stirs occasion, vertical type speed reducer (change gear) has standard type, but the vertical type speed reducer (change gear) of standard type can not bear large radial force and axial force, first because speed reducer output shaft is to bear axial force by selfaligning roller bearing, when next be the more important thing is because work, suffered radial force and the axial force of speed reducer all can directly act on Gearbox, the support span of output shaft front and back bearings is short simultaneously, integrally-built unstable while easily causing speed reducer work, in addition, the sealing of the output terminal of the vertical type speed reducer (change gear) of standard type neither be reliable especially, just there is certain pollution hidden trouble in the stirring occasion for the high medicine powder of hygienic requirements.
Summary of the invention
In view of the deficiencies in the prior art, when the purpose of this utility model aims to provide a kind of work, overall structure is stable, can bear large radial force and axial force, good seal performance, the vertical type speed reducer (change gear) of long service life.
For solving the problems of the technologies described above, the utility model takes following technological scheme to complete:
Vertical type speed reducer (change gear), comprise speed reducer, speed reducer internal gear transmission parts, output shaft and output flange, output flange is positioned at the bottom of speed reducer, output shaft down passes outward in the center hole of output flange, it is characterized in that: output flange is up big and down small extended type plummer block housing body structure, the upper-end surface of output flange is provided with inside and outside mounting hole, be fixedly connected with speed reducer by interior mounting hole output flange, be fixedly connected with speed reducer scaffold by outer mounting hole output flange, the lower port seat of output flange arranges bearing bore, mounted in pairing mode tapered roller bearing back-to-back in bearing bore, the lower end mouth of bearing bore arranges lower oil sealing, the upper end-hole position of output flange arranges oil sealing.
The vertical type speed reducer (change gear) of technique scheme, comparison with standard type speed reducer, maximum is not both: 1. output flange adopts up big and down small extended type plummer block housing body structure, the lower port seat of output flange arranges the tapered roller bearing of mounted in pairing mode back-to-back, its beneficial effect is, first tapered roller bearing is compared selfaligning roller bearing and can be born much bigger axial force, secondly the support span of output shaft front and back bearings is lengthened, can make the working stability of output shaft improve, secondly the suffered radial force of output shaft all can be delivered on the speed reducer scaffold being fixedly connected with output flange by output flange with axial force again, and can not be delivered on Gearbox, thereby while making speed reducer work, overall structure is stable, can bear large radial force and axial force, long service life.2. because output flange has adopted extended type structure, so the sealing of the output terminal of vertical type speed reducer (change gear) just can before and after twice settings, and distance between two seals can be very long, thereby the sealability that improves speed reducer, makes speed reducer be particularly suitable for the stirring occasion of the high medicine powder of hygienic requirements.
As preferably, be positioned at the oil sealing chamber of bottom at the lower oil sealing of bearing bore lower end mouth setting, bottom fixedly mounts in the lower end surface of output flange by screw.The maximum diameter position that described output shaft and the tactile intermediate section position of sealing-in that oils are output shaft.Described upper and lower oil seals is respectively established two.
Brief description of the drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural drawing of vertical type speed reducer (change gear) of the present utility model,
Fig. 2 is the structural drawing of the vertical type speed reducer (change gear) of prior art standard type.
