Description
Technical field
The utility model is related to a kind of fixed structures, and in particular to a kind of simple in structure, easy to use, repair does not need to change
Entire water pilot bearing substantially reduces the water pilot bearing fixed structure of large pump maintenance cost.
Background technology
Existing large-scale vertical pumps guide bearing fixation, and there are mainly two types of connection types：
1, rubber bearing bush and bearing body are fixed by being interference fitted；
It mostly uses and breathes out furan structure, rubber bush is generally directly pressed by transition cooperation in bearing body, then is subject to screw
It is fixed；Or directly pour colloid on bearing body, it is produced by the Interference size of bearing body inner cylinder face and guide bearing external cylindrical surface
Raw pretightning force, makes bearing when equipment is run, does not generate radial and axial displacement.
2, rubber bearing bush and bearing body are bolted, and bearing is fixed on by stud and nut by the flange that bearing carries
On body, bearing is made not generate radial and axial displacement when equipment is run.
The first structure the problem is that：The axial force or radial load of large vertical water pumps are all very big, water pilot bearing
Service life all will not be very long, and through operation after a period of time, the rubber bush of water pilot bearing will be worn, and needs to carry out more
It changes, just water pilot bearing must integrally be removed, all replaced at this time, dismounting bothers, and replacement cost is higher.
Second of structure the problem is that：Conveying be corrosive medium when, due to the corrosiveness of medium, frequently result in
The stud and nut of fastening fail, and guide bearing is made to generate axial displacement (guide bearing for mainly pumping lowest part).To make pump not
Energy safe and stable operation, it is serious that pump lower part is made to damage.
Utility model content
In view of the above-mentioned problems, the main purpose of the utility model is to provide a kind of simple in structure, easy to use, repair is not
Entire water pilot bearing is needed to change, the water pilot bearing fixed structure of large pump maintenance cost is substantially reduced.
The utility model is to solve above-mentioned technical problem by following technical proposals：A kind of water pilot bearing fixed knot
Structure, the water pilot bearing fixed structure include：Bearing body, bearing shell, arc-shaped pressing plate, connecting key, ring-shaped groove；Bearing body
Inner surface is equipped with the ring-shaped groove, and the arc-shaped pressing plate, the bearing shell and bearing body are fixed in ring-shaped groove
Between by connect be keyed, the thickness and ring-shaped groove of arc-shaped pressing plate are highly consistent, be provided on arc-shaped pressing plate one with company
Connect the consistent groove of width of key；The end face that the connecting key is higher by guide bearing extends in groove.
In specific embodiment of the utility model, after arc-shaped pressing plate installs, with two trip bolts, pass through axis
It holds two through-holes opened up on body and is screwed into arc-shaped pressing plate, arc-shaped pressing plate is fixed in the ring-shaped groove on bearing body.
In specific embodiment of the utility model, the arc-shaped pressing plate is 90 degree of arc-shaped pressing plate.
The positive effect of the utility model is：Water pilot bearing fixed structure provided by the utility model, due to axis
Connecting key is equipped with watt between bearing body will not cause connecting key to fail when conveying is corrosive medium, will not make guide bearing
Axial displacement is generated, to enable pump safe and stable operation, pump lower part will not be made to damage.And not when replacing guide bearing
Need integral replacing, it is only necessary to replace bearing shell, reduce the expense for replacing accessory, also shorten the time.This practicality is new
Type is simple in structure, easy to use；Repair does not need to change entire water pilot bearing, substantially reduces large pump maintenance cost.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
Specific implementation mode
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
Fig. 1 is the overall structure diagram of the utility model, and Fig. 2 is the left view of Fig. 1, as shown in Figs. 1-2：This practicality is new
The water pilot bearing fixed structure that type provides, including：Bearing body 1, bearing shell 2, arc-shaped pressing plate 3, connecting key 5, ring-shaped groove 7；Axis
The inner surface for holding body 1 is equipped with ring-shaped groove 7, is fixed with arc-shaped pressing plate 3 in ring-shaped groove 7, leads between bearing shell 2 and bearing body 1
Cross connecting key 5 connection, the thickness and ring-shaped groove 7 of arc-shaped pressing plate 3 are highly consistent, be provided on arc-shaped pressing plate 3 one with connect
The groove 6 of 5 equivalent width of key；The end face that connecting key 5 is higher by guide bearing extends in groove 6.
After arc-shaped pressing plate 3 installs, with two trip bolts 4, circle is screwed by two through-holes opened up on bearing body 1
Arc-shaped pressing plate 3 is fixed in the ring-shaped groove 7 on bearing body 1 by arc pressuring plate 3.
The arc-shaped pressing plate that the arc-shaped pressing plate 3 of the utility model is 90 degree.
After bearing shell 2 installs on bearing body 1, the length of connecting key 5 will be higher by the end face of bearing shell 2, and the size being higher by is answered
Less than the depth of groove 6.Then arc-shaped pressing plate 3 is packed into ring-shaped groove 7, the groove 6 on arc-shaped pressing plate 3 and connecting key
5 are harmonious, and connecting key 5 outstanding mainly prevents arc-shaped pressing plate 3 from making circumferential movement when equipment is run.On arc-shaped pressing plate 3
Equipped with 4 holes 301, two holes on large radius circumferential position are screw hole.After arc-shaped pressing plate 3 installs, with two fastening spiral shells
Nail 4, is screwed into arc-shaped pressing plate 3 by two through-holes opened up on bearing body 1, is used with making the radially fixed of arc-shaped pressing plate 3.
The installation fixed structure of large size guide bearing provided by the utility model, is connected between bearing shell and bearing body by connecting key
It connects, fixed bearing shell prevents it from moving radially in the circumferential position of bearing body.Groove on arc-shaped pressing plate 3 with it is outstanding
Connecting key is harmonious, and connecting key outstanding mainly prevents arc-shaped pressing plate 3 from making circumferential movement when equipment is run.In arc-shaped pressure
After plate 3 installs, with two holding screws, it is screwed into semicircle pressing plate by two through-holes opened up on bearing block, it is fixed semicircle
Pressing plate.Connecting key will not be caused to fail when conveying is corrosive medium due to being equipped with connecting key between bearing shell and bearing body,
Guide bearing will not be made to generate axial displacement, to enable pump safe and stable operation, pump lower part will not be made to damage.And more
Integral replacing is not needed when changing guide bearing, it is only necessary to be replaced bearing shell, be reduced the expense for replacing accessory, when shortening yet
Between.
The utility model is simple in structure, easy to use；Repair does not need to change entire water pilot bearing, substantially reduces large pump
Maintenance cost.
