Abstract

The invention relates to the technical field of vertical stirring equipment driving devices, in particular to a vertical transmission structure which can reduce axial height, save space and solve the problem of oil leakage at the same time.

Description

Vertical transmission structure

Technical Field

The invention relates to the technical field of driving devices of vertical stirring equipment, in particular to a vertical transmission structure.

Background

Currently, in the vertical stirring field, a general structure is shown in fig. 1, wherein 1 is a speed reducer, 2 is a supporting sleeve of the speed reducer, 3 is a speed reducer output shaft, 4 is a speed reducer output shaft oil seal, 5 is a stirring shaft, the speed reducer output shaft 4 and the stirring shaft 5 are connected through a coupler 6 and transmit torque, 8 is an upper oil seal of the stirring shaft and plays a role in sealing, 9 is a bearing at the upper end of the stirring shaft and plays a role in supporting and positioning the stirring shaft; the above structure has two main disadvantages: 1. the axial dimension is longer, the larger space is occupied, is particularly inconvenient when being used vertically; 2. the speed reducer output shaft oil seal is at the speed reducer lower extreme, and inside lubricating oil uses for a long time has the risk of revealing.

Disclosure of Invention

In order to solve the problems that the existing axial height is too high, the occupied space is large, and the oil leakage risk exists, the invention provides a vertical transmission structure which can reduce the axial height, save the space and solve the oil leakage problem.

The technical scheme is as follows: the utility model provides a vertical transmission structure, its includes the reduction gear, the reduction gear is installed in the supporting seat, the (mixing) shaft is connected to the reduction gear bottom, its characterized in that, the reduction gear includes sleeve and reduction gear casing in the middle of the reduction gear, the reduction gear casing with be provided with the reduction gear bearing between the sleeve in the middle of, the lower flange is connected to reduction gear casing bottom, the step hole has been seted up in the middle of the lower flange up end, be provided with the lantern ring on the step face in step hole, the lantern ring inboard is provided with the baffle ring, the (mixing) shaft passes the step hole passes through the key connection the lower flange, the (mixing) shaft outer peripheral face seted up with baffle ring complex annular.

The baffle ring is further characterized in that the baffle ring is formed by splicing two half semicircular rings;

an upper flange is arranged on the upper end face of the middle sleeve of the speed reducer and is connected with the supporting seat, and a speed reducer oil seal is arranged between the speed reducer and the upper flange;

the supporting seat is supported on the bottom plate, a through hole is formed in the middle of the bottom plate, the upper end face of an opening of the through hole is an annular boss, an annular groove corresponding to the annular boss is formed in the bottom of the lower flange, and a gap is reserved between the lower flange and the bottom plate.

After the invention is adopted, the traditional coupling is canceled, the speed reducer shell and the lower flange replace to transmit torque to the stirring shaft, the stirring shaft support bearing and the oil seal on the stirring shaft are canceled, the speed reducer shell and the lower flange share the internal speed reducer bearing and the oil seal with the speed reducer, the axial space is saved, the oil seal position is positioned at the upper part of the speed reducer, the oil leakage risk does not exist at the bottom, the oil leakage problem is effectively solved, the stirring shaft is supported by the lantern ring and the baffle ring on the lower flange in a matched manner, the structure is more compact, the length of the stirring shaft and the height of the support seat are also reduced, the overall axial height is greatly reduced, and the axial space is saved.

Drawings

FIG. 2 is a schematic diagram of the structure of the present invention.

Detailed Description

See the figure 2 shows, a vertical transmission structure, it includes the reduction gear, the reduction gear is installed in supporting seat 3, the (mixing) shaft 12 is connected to the reduction gear bottom, the reduction gear includes sleeve 4 and reduction gear casing 5 in the middle of the reduction gear, be provided with reduction gear bearing 6 between reduction gear casing 5 and the intermediate sleeve 4, the lower flange 9 is passed through to reduction gear casing 5 bottom, the step hole has been seted up in the middle of the lower flange 9 up end, be provided with the lantern ring 8 on the step face in step hole, the lantern ring inboard is provided with baffle ring 7, baffle ring 7 is by the concatenation of two semicircle rings of halving, form a complete baffle ring jointly, the thickness of retaining ring can be confirmed after the size of stirring axle 12 bearing axial force is calculated, baffle ring 7 is realized outside diameter by lantern ring 8 and is contained spacingly, stirring axle 12 passes step hole and passes through key connection lower flange 9, the annular with baffle ring 7 matched is seted up to stirring axle 12 outer peripheral face, stirring axle 12 is stabilized and is supported on baffle ring 7.

The supporting seat 3 is supported on the bottom plate 11, a through hole 13 is formed in the middle of the bottom plate 11, the upper end face of an opening of the through hole 13 is an annular boss, an annular groove corresponding to the annular boss is formed in the bottom of the lower flange 9, the annular boss and the annular groove are not in contact with each other, a gap is reserved between the lower flange 9 and the bottom plate 11, and the annular boss and the annular groove can play a certain limiting role.

The upper flange 1 is installed to the upper end face of sleeve 4 in the middle of the reduction gear and goes up flange 1 and be connected with supporting seat 3, is provided with reduction gear oil blanket 2 between reduction gear and the upper flange 1, and relative rotation is located reduction gear upper portion, and the problem of oil leak can be reached to reduction gear oil blanket 2 on only needing an upper portion of whole structure, and the bottom does not have rotatory oil blanket, does not have the oil leak risk.

In the invention, the output shaft of the motor outputs power to the speed reducer, the gear mechanism 10 in the speed reducer transmits torque to the speed reducer shell 5, the speed reducer shell 5 is transmitted to the lower flange 9, and the lower flange is transmitted to the stirring shaft 12 to rotate.
