Description
Technical field
This utility model relates to a kind of fixing device, specifically a kind of packing_seal bar fixing device.
Background technology
Now with the fast development of food industry, the technology of pipelining equipment is required also day by day to improve by food machinery field.Fixed form for the sealing shroud in conventional dynamic seal structure is to adopt holding screw to fix, sealing shroud can loosen rotation in use for some time, sealing shroud can be caused to leak, and power transmission shaft is also damaged to some extent, the equipment that affects runs and service life, and causing that production efficiency is low affects production cost.
Utility model content
The purpose of this utility model is to provide a kind of stable performance, simple in construction, replacing is convenient, production cost is low sealing sleeve fixture mechanism.
For achieving the above object, the technical solution of the utility model includes power transmission shaft (1) and sealing shroud (2), described power transmission shaft (1) and sealing shroud (2) fit, it is characterized in that, described power transmission shaft (2) right part diameter is more than left part diameter, pillow block rank (3) are formed at power transmission shaft (2) middle part, described sealing shroud (2) is linked in power transmission shaft (1) right part, described sealing shroud (2) left side is provided with retainer ring (5, 6, 7) and draw-in groove (4), described retainer ring (5, 6, 7) it is linked in draw-in groove (4) place by bolt (8), described retainer ring (5, 6, 7) both sides are provided with double wedge (9) up and down, described sealing shroud (2) left side is provided with the groove (10) corresponding with double wedge (9), described groove (10) coincide with double wedge (9), described retainer ring (5, 6, 7) retainer ring (5) and lower retainer ring (6) are also included, fixed ring (5) and lower retainer ring (6) joint are provided with fixing hangers (7), fixed ring (5) and lower retainer ring (6) run through fixing hangers (7) by bolt (8) and connect fixing, described draw-in groove (4) bottom side and fixing hangers (7) inside contact surface and power transmission shaft (1) central axis.
Owing to adopting technique scheme, the beneficial effects of the utility model:
1, realized by simple structure, it is to avoid the rotation of sealing shroud and moving axially, it is prevented that occur sealing unsuccessfully because sealing shroud rotates to cause, improve sealing effectiveness, improve power transmission shaft service life, reduce spoilage, improve work efficiency.
2, retainer ring is changed also more convenient, and production cost is low, reduces maintenance cost, reduces production cost.
Accompanying drawing explanation
In conjunction with accompanying drawing, this utility model is described further.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
In figure: 1, power transmission shaft, 2, sealing shroud, 3, pillow block rank, 4, draw-in groove, 5, upper retainer ring, 6, lower retainer ring, 7, fixing hangers, 8, bolt, 9, double wedge, 10, groove.
Detailed description of the invention
As shown in Figure 1-2, this utility model includes power transmission shaft 1 and sealing shroud 2, described power transmission shaft 1 and sealing shroud 2 fit, it is characterized in that, described power transmission shaft 2 right part diameter is more than left part diameter, pillow block rank 3 are formed in the middle part of power transmission shaft 2, described sealing shroud 2 is linked in power transmission shaft 1 right part, it is provided with retainer ring 5 on the left of described sealing shroud 2, 6, 7 and draw-in groove 4, described retainer ring 5, 6, 7 are linked in draw-in groove 4 place by bolt 8, described retainer ring 5, 6, about 7 both sides are provided with double wedge 9, the groove 10 corresponding with double wedge 9 it is provided with on the left of described sealing shroud 2, described groove 10 coincide with double wedge 9, described retainer ring 5, 6, 7 also include retainer ring 5 and lower retainer ring 6, fixed ring 5 and lower retainer ring 6 joint are provided with fixing hangers 7, fixed ring 5 and lower retainer ring 6 run through fixing hangers 7 by bolt 8 and connect fixing, described draw-in groove 4 bottom side and fixing hangers 7 inside contact surface and power transmission shaft 1 central axis.
Operation principle of the present utility model: coordinate installation equipment to realize limiting the moving axially of sealing shroud 2 by retainer ring 5,6,7 and draw-in groove 4, by retainer ring 5,6,7, draw-in groove 4, double wedge 9 and groove 10 coordinate the rotation limiting sealing shroud 2.
