The utility model discloses a kind of fixed mechanism of base bearing sheath, include bracing frame and shaft, described bracing frame includes base plate and the annular brace cylinder being fixed on base plate, at least one opening window is provided with the side wall of the annular brace cylinder, the top of described annular brace cylinder is fixed support and is provided with annular shaft bearing, the annular shaft bearing inwall is fixedly installed tetrafluoroethene set, rotate in the tetrafluoroethene set and be provided with sheath, the inner chamber of the sheath is the shaft linkage hole for shaft grafting, the lower axial end of described sheath is fixedly installed sheath base plate, multiple bolt fixing holes are offered on described sheath base plate, described shaft is plugged in shaft linkage hole, and be fixed on the axial end of shaft through bolt fixing hole by fastening bolt.This utility model has the advantages that to change easy to maintenance.
Description
Technical field
This utility model is related to a kind of fixed mechanism of base bearing sheath.
Background technology
In stirring system, base bearing is a kind of common Auxiliary support, and it can efficiently control the swing of shaft, carry
The stability of high equipment operation.Because which need to carry out long-term sliding friction, therefore the sheath of its protection shaft need to be carried out periodically more
Change, to guarantee the normal operation of equipment.
Ordinary circumstance lower jacket and shaft using holding screw carry out it is radially fixed couple, to prevent sheath and shaft
Generation relative motion.But when the sheath more serious or holding screw of abrasion is worn, sheath is just difficult to split out, and causes plant maintenance
Time greatly prolongs.If separately have replacing accessory tightening screw also more difficult same last time to upper.
Utility model content
The purpose of this utility model is, for the shortcoming and defect for overcoming prior art to exist, and to provide a kind of structure design
Rationally, change the fixed mechanism of base bearing sheath easy to maintenance.
For achieving the above object, the technical solution of the utility model is to include bracing frame and shaft, described support
Frame includes base plate and the annular brace cylinder being fixed on base plate, is provided with least one and opens on the side wall of the annular brace cylinder
Mouth window, the top of described annular brace cylinder are fixed support and are provided with annular shaft bearing, and the annular shaft bearing inwall is fixedly installed
There is tetrafluoroethene set, rotate in the tetrafluoroethene set and be provided with sheath, the inner chamber of the sheath is the stirring for shaft grafting
Axle linkage hole, the lower axial end of described sheath are fixedly installed sheath base plate, offer multiple spiral shells on described sheath base plate
Bolt fixing hole, described shaft are plugged in shaft linkage hole, and are fixed on through bolt fixing hole by fastening bolt and stir
Mix on the axial end of axle.
It is inwardly protruding at the inwall lower edge of described annular shaft bearing to be provided with circular orientation convex tendon, institute further to arrange
The supported underneath of the tetrafluoroethene pipe stated is fixed on the circular orientation convex tendon, and is provided with footpath on the side wall of the annular shaft bearing
To connecting hole, screw is fixed on the outer wall of tetrafluoroethene pipe through radially connected hole.
The utility model has the advantages that being to fix the axial bolts that the fixing screws of sheath are changed to bottom, spiral shell is so fixed
Bolt just will not be destroyed, while the position of accessory bolt is also easily guaranteed that, change simple-to-maintain convenient.
This utility model is described further with reference to specification drawings and specific embodiments.
Description of the drawings
Fig. 1 this utility model specific embodiment structural representations.
Specific embodiment
This utility model is specifically described below by embodiment, is served only for carrying out further this utility model
Explanation, it is impossible to be interpreted as the restriction to this utility model protection domain.
Specific embodiment of the present utility model as shown in Figure 1, includes bracing frame 1 and shaft 2, described support
Frame 1 includes base plate 11 and the annular brace cylinder 12 being fixed on base plate, be provided with the side wall of the annular brace cylinder 12 to
A few openning 121, the openning be used for when following fastening bolts are loaded and unloaded it is convenient it is lateral operate, the present embodiment openning
121 are provided with 4, and circumferentially uniform.
Additionally, support is fixed in the top of the annular brace cylinder 12 described in the present embodiment is provided with annular shaft bearing 3, the annular
3 inwall of bearing block is fixedly installed tetrafluoroethene set 4, rotates and be provided with sheath 5 in the tetrafluoroethene set 4, the inner chamber of the sheath 5
It is the shaft linkage hole 51 for shaft grafting, the lower axial end of described sheath 5 is fixedly installed sheath base plate 6, this
The embodiment sheath base plate 6 is fixed on sheath 5 by the way of welding, offers multiple bolts on described sheath base plate 6
Fixing hole 61, described shaft 2 are plugged in shaft linkage hole 51, and solid through bolt fixing hole 61 by fastening bolt 7
On the axial end of shaft 2.
Additionally, inwardly protruding at the inwall lower edge of annular shaft bearing 3 described in the present embodiment be provided with circular orientation convex tendon
31, the supported underneath of described tetrafluoroethene pipe 4 is fixed on the circular orientation convex tendon 31, and the side wall of the annular shaft bearing 3
On be provided with radially connected hole 32, screw 8 is fixed on the outer wall of tetrafluoroethene pipe 4 through radially connected hole 32.
