Abstract
The utility model provides a kind of three supporting type water lubriucated bearings, including bearing insert and supporting element, and the bearing insert passes through internal fixed supporting element and transmission shaft three-point contact.The utility model by with transmission shaft three-point contact, can reduce bearing dismantling difficulty, mitigating weight of equipment simultaneously reduces frictional resistance.
Description
Technical field
The utility model relates to transmission technical fields, and in particular to a kind of three supporting type water lubriucated bearings.
Background technique
For the water lubrication shaft bearing structure in marine propulsion shafting, traditional approach generally uses the water lubrication of strip type bearing shell
Bearing, bearing shell are all made of complete cycle arrangement in bearing insert, and not only the weight of bearing shell itself is big, but also leads to bearing insert
Processing is also complex, needs to open many bolts hole along axial direction on bearing insert, significantly increases manufacture difficulty and cost.?
Installation, lath-shaped bearing shell use screw-driving or dovetail groove fixed form, need to tighten the screw on all laths one by one,
Since mostly not only result in shaft bearing plate installation difficulty big for lath quantity, and bearing bore diameter size Control is also extremely difficult.
Utility model content
In view of this, the present invention provides a kind of three supporting type water lubriucated bearings, can reduce bearing dismantling difficulty,
Mitigate weight of equipment and reduces frictional resistance.
Specific embodiment of the present utility model is as follows:
A kind of three supporting type water lubriucated bearings, including bearing insert and supporting element, the bearing insert pass through internal fixed
Supporting element and transmission shaft three-point contact.
Further, the supporting element is three groups of bearing laths, and three groups of bearing laths are evenly arranged on bearing insert inner wall；Often
One group of bearing lath is fixed on bearing insert inner wall by flexible fastening seat.
Further, the bearing lath upper and lower surfaces are planar structure, are provided with thin pad below every bearing lath
Piece, shim liner lower section are equipped with elastomeric pad.
Further, the bearing lath is manufactured using high molecular material.
Further, the supporting element is monoblock type bearing shell, and the monoblock type bearing shell passes through three supporting planes and transmission
Axis contact.
The utility model has the advantages that
1, the utility model smart structural design, by with transmission shaft three-point contact, water lubriucated bearing can be greatly decreased
The quantity of bearing shell or lath not only reduces the difficulty of processing of bearing insert, additionally aids and mitigates weight of equipment and reduce friction
Resistance makes bearing be easier to assemble, and has very extensive application prospect.
2, the utility model bearing lath upper surface uses the planar structure for advantageously forming lubrication, and lower surface design has
The shim liner of plane and the integral supporting structure of elastomeric pad cannot be only used for adjusting bearing clearance, can also make bearing lath edge
Length direction can adapt to the deformation of axis automatically, and the adaptive ability of bearing can be improved, effectively promoted bearing self-lubricating property, from
Centring property is further reduced the fretting wear of bearing, alleviates the friction noise of slow-speed of revolution lower bearing, in high performance water lubricating axis
It is with high application prospect to hold field.
3, the bearing lath of the utility model uses high molecular material, can provide lower rub in shafting starting, operating
Coefficient is wiped, helps to reduce the friction of bearing, abrasion, further increases the service life of bearing.
Detailed description of the invention
Fig. 1 is the diagrammatic cross-section that the utility model uses bearing lath；
Fig. 2 is the diagrammatic cross-section that the utility model uses bearing shell.
Wherein, 1- bearing insert, 2- bearing lath, 3- flexible fastening seat, 4- locked spacer, 5- fastening bolt, the thin pad of 6-
Piece, 7- elastomeric pad, 8- transmission shaft, 9- monoblock type bearing shell.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
The utility model provides a kind of three supporting type water lubriucated bearings, and embodiment one is as shown in Figure 1, include bearing insert
1, bearing lath 2, flexible fastening seat 3, locked spacer 4, fastening bolt 5, shim liner 6, elastomeric pad 7.
Bearing insert 1 is the outer structural parts of bearing, is in thin shelled tubular structure, is provided with three sets on 1 inner wall of bearing insert
Bearing lath 2 and flexible fastening seat 3, three groups of bearing laths 2 are evenly arranged on 1 inner wall of bearing insert, and bearing lath 2 passes through elasticity
Fixing seat 3 is fixed on 1 inner wall of bearing insert, and the contact surface of flexible fastening seat 3 and bearing lath 2 is plane.Flexible fastening
Seat 3 is fixed on 1 inner wall of bearing insert by two column fastening bolts 5, and fastening bolt 5 loosens in order to prevent, is provided with stop pad
Piece 4.
2 upper and lower surfaces of bearing lath are planar structure, are manufactured using high molecular material.It is set below every bearing lath 2
Shim liner 6 is set, elastomeric pad 7 is installed below shim liner 6.Shim liner 6 is manufactured using corrosion-resistant metallic material, simultaneously because bearing
Lath 2 uses high-mechanic, self-lubricating nonmetallic materials, can provide lower coefficient of friction in shafting starting, operating, helps
In the friction, the abrasion that reduce bearing, the service life of bearing is further increased.
Three groups of bearing laths 2 and 8 contact area of transmission shaft are the working face of bearing, are used to support the weight of transmission shaft 8, are limited
The radial displacement of transmission shaft 8 processed, and partner the pair that rubs with transmission shaft 8.
Embodiment two is as shown in Fig. 2, be fixed with monoblock type bearing shell 9 in bearing insert 1.Monoblock type bearing shell 9 is equipped with A, B, C tri-
A supporting plane.These three supporting planes are the working surfaces of bearing, and monoblock type bearing shell 9 and transmission shaft 8 directly contact, and limit
The radial displacement of transmission shaft 8.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection scope.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
