Description
A BEARING ASSEMBLY
FIELD OF THE INVENTION
This invention relates to a bearing. In particular, the invention relates to a bearing assembly and to a bearing.
BACKGROUND
In the field of mechanical apparatus, and the like, use is often made of bearings to inhibit wear between parts, or components, or the like, which move relative to each other while in contact with each other. In some cases, components are arranged to be in sliding contact with each other. For example, in the case of mechanical hoisting apparatus, rope conveyance apparatus, elevators, or lifts, and the like, elongate elements, such as steel wire wound ropes, or cables, and the like, are often guided through the apparatus and make sliding contact with the apparatus when in use.
In the case of conveyances arranged to travel along a constrained path defined by an elongate element, such as a wire wound rope, or cable, or the like, the conveyance is often guided along the elongate element by means of a constraining mechanism on the conveyance. The constraining mechanism is typically arranged to run along the elongate element so as to guide the conveyance along the elongate element. Frictional contact typically takes place between the elongate element and the constraining mechanism as the conveyance is guided along the elongate element. In some cases constraining mechanisms make use of guide rollers arranged to roll along the elongate element. In other cases constraining mechanisms make use of longitudinal low friction material slippers, or slide bearings.
It has been found that constraining mechanisms making use of guide rollers provide relatively low frictional resistance but are relatively maintenance intensive.
Furthermore, constraining mechanisms making use of guide rollers typically have rather bulky and relatively complicated support structures which are sometimes impractical. In the case of longitudinal low friction material slippers, or slide bearings, it has been found that constraining mechanisms which make use thereof suffer from relatively high rates of wear and cause the elongate element to suffer from wear as well.
Traditionally, the materials of which the longitudinal low friction material slippers have been made have been relatively soft to inhibit wear on the elongate element.
Such materials include non-magnetic metals, such as brass, bronze, and the like, as well as plastics, nylons, urethanes and the like. Although such materials inhibit wear on the elongate element, these materials have been found to exhibit relatively high wear rates resulting in relatively high levels of consumption, frequent operational downtime and relatively high production cost losses, in certain cases. Attempts have been made to provide lubrication between the elongate element and such constraining mechanisms, but these attempts have met with limited success. The use of relatively soft magnetic metals has been investigated. However, such metals typically have higher coefficients of friction than the non magnetic metals mentioned above which typically causes higher wear rates of the elongate element which is undesirable.
It is an object of this invention to provide a constraining mechanism which is simpler than those which make use of guide rollers and which has a lower rate of wear than the constraining mechanisms of the longitudinal low friction material slipper type.
SUMMARY OF THE INVENTION
According to the invention, there is provided a bearing assembly including a bearing mount and a bearing on the bearing mount, the bearing being of a ceramic material.
The bearing may be defined by a plurality of ceramic tiles secured on the bearing mount.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to Figures 1 to 3 of the drawings, a bearing assembly, in accordance with the invention, is generally indicated by reference numeral 10. The bearing assembly can typically be used as a constraining mechanism in a high speed winding operation, or the like, or another kind of conveyance, for example. When used for such a purpose, the assembly 10 is typically mounted on a conveyance apparatus, or structure, schematically indicated at 11. It is envisaged that the assembly 10 can advantageously be used in hoisting, rope conveying and elevator applications. However, it is to be
5 appreciated that the bearing assembly of the invention is not limited for use as a constraining mechanism in such applications only, but extends to use as a slide bearing in general.
The bearing assembly 10 includes a bearing mount, generally indicated by reference numeral 12, and a bearing 14. The bearing 14 is on the bearing mount 12 and is of a ceramic material. The mount 12 can typically be of metal.
The bearing 14 can be of a moulded ceramic material. The bearing 14 can be cast to any desired shape or size depending on the application. The bearing 14 can be defined by a plurality of ceramic tiles or strips secured on the bearing mount 12. The bearing 14 can be secured on the bearing mount 12 by bonding. Instead, or in addition, the bearing 14 can be secured on the bearing mount 12 by any appropriate mechanical arrangement.
Instead, the bearing 14 can be defined by at least two parts 14.1, 14.2. The parts 14.1, 14.2 of the bearing 14 can be secured on the bearing mount 12 by mechanical means, such as by means of screw-threaded fasteners, or the like, for example.
Instead, or in addition, the parts can be secured on the bearing mount 12 by bonding.
The bearing mount 12 is typically defined by two parts 12.1, 12.2. The parts 12.1, 12.2 are secured to one another releasably to enable the parts 12.1, 12.2 to be separated from one another. The bearing 14 is defined between the two parts 12.1, 12.2 of the bearing mount 12 and defines a bearing passage 16 extending through the bearing assembly 10 when the two parts 12.1, 12.2 of the bearing mount 12 are releasably secured together. The passage 16 is arranged to receive an elongate component, such as an elongate element 17 in the form of a wire wound rope, or the like, for example, in sliding relationship therethrough. The bearing passage 16 is typically cross-sectionally generally circular in shape. It will be appreciated that when the element 17 is received in sliding relationship in the passage 16, the axial movement along the element 17 can be achieved but lateral movement relative to the element 17 is inhibited.
The bearing assembly 10 includes a bearing mount, generally indicated by reference numeral 12, and a bearing 14. The bearing 14 is on the bearing mount 12 and is of a ceramic material. The mount 12 can typically be of metal.
The bearing 14 can be of a moulded ceramic material. The bearing 14 can be cast to any desired shape or size depending on the application. The bearing 14 can be defined by a plurality of ceramic tiles or strips secured on the bearing mount 12. The bearing 14 can be secured on the bearing mount 12 by bonding. Instead, or in addition, the bearing 14 can be secured on the bearing mount 12 by any appropriate mechanical arrangement.
Instead, the bearing 14 can be defined by at least two parts 14.1, 14.2. The parts 14.1, 14.2 of the bearing 14 can be secured on the bearing mount 12 by mechanical means, such as by means of screw-threaded fasteners, or the like, for example.
Instead, or in addition, the parts can be secured on the bearing mount 12 by bonding.
The bearing mount 12 is typically defined by two parts 12.1, 12.2. The parts 12.1, 12.2 are secured to one another releasably to enable the parts 12.1, 12.2 to be separated from one another. The bearing 14 is defined between the two parts 12.1, 12.2 of the bearing mount 12 and defines a bearing passage 16 extending through the bearing assembly 10 when the two parts 12.1, 12.2 of the bearing mount 12 are releasably secured together. The passage 16 is arranged to receive an elongate component, such as an elongate element 17 in the form of a wire wound rope, or the like, for example, in sliding relationship therethrough. The bearing passage 16 is typically cross-sectionally generally circular in shape. It will be appreciated that when the element 17 is received in sliding relationship in the passage 16, the axial movement along the element 17 can be achieved but lateral movement relative to the element 17 is inhibited.
6 In one embodiment, the bearing 14 is releasably mounted on the bearing mount 12. Accordingly, in such a case, the bearing 14 can be removed and replaced by separating the parts 12.1, 12.2 of the bearing mount 12 from one another. The parts 12.1, 12.2 can be secured relative to one another by means of conventional screw-threaded fasteners, such as bolts, screws, or the like, extending through apertures 18.
The bearing mount 12 defines a bearing seat 20 when the two parts 12.1, 12.2 are releasably secured together. Tlie bearing 14 is seated on the bearing seat 20 releasably.
Each part 12.1, 12.2 of the bearing mount 12 defines a cross-sectionally generally semi-circular shaped surface 20.1, 20.2 such that when the parts 12.1, 12.2 of the bearing mount 12 are releasably secured together, the bearing mount 12 defines a cross-sectionally generally circular shaped bearing seat 20. The bearing 14 defines an outer cross-sectionally generally circular shaped surface arranged to seat between the bearing surfaces 20.1, 20.2 of the parts 12.1 12.2 of the bearing mount 12 when the parts of the bearing mount 12 are secured together.
Referring now to Figure 4 of the drawings, in which like reference numerals have been used to designate similar parts, unless otherwise stated, another bearing assembly in accordance with the invention is generally indicated by reference numeral 110.
The bearing assembly 110 is similar to the assembly 10 save that the one part 112.2 of the bearing mount 112 of the assembly 110 has flange formations 113.1, 113.2.
As can best be seen in Figure 4, the bearing 14 has a body formed from a ceramic material. The body can typically be made up of two parts 14.1, 14.2 as already mentioned. When mounted on the mount 112 the parts 14.1, 14.2 together form the bearing 14. Each bearing part 14.1, 14.2 defines an elongate body having an axially extending cross-sectionally part circular, preferably generally semi-circular, outer surface 14.3. Each bearing part 14.1, 14.2 further defines an axially extending cross-sectionally part circular, preferably generally semi-circular, inner surface 14.4. When in a mouiited condition on the mount 112, the inner surfaces 14.4 together define the passage 16 through which the elongate component 17 can extend.
The bearing mount 12 defines a bearing seat 20 when the two parts 12.1, 12.2 are releasably secured together. Tlie bearing 14 is seated on the bearing seat 20 releasably.
Each part 12.1, 12.2 of the bearing mount 12 defines a cross-sectionally generally semi-circular shaped surface 20.1, 20.2 such that when the parts 12.1, 12.2 of the bearing mount 12 are releasably secured together, the bearing mount 12 defines a cross-sectionally generally circular shaped bearing seat 20. The bearing 14 defines an outer cross-sectionally generally circular shaped surface arranged to seat between the bearing surfaces 20.1, 20.2 of the parts 12.1 12.2 of the bearing mount 12 when the parts of the bearing mount 12 are secured together.
Referring now to Figure 4 of the drawings, in which like reference numerals have been used to designate similar parts, unless otherwise stated, another bearing assembly in accordance with the invention is generally indicated by reference numeral 110.
The bearing assembly 110 is similar to the assembly 10 save that the one part 112.2 of the bearing mount 112 of the assembly 110 has flange formations 113.1, 113.2.
As can best be seen in Figure 4, the bearing 14 has a body formed from a ceramic material. The body can typically be made up of two parts 14.1, 14.2 as already mentioned. When mounted on the mount 112 the parts 14.1, 14.2 together form the bearing 14. Each bearing part 14.1, 14.2 defines an elongate body having an axially extending cross-sectionally part circular, preferably generally semi-circular, outer surface 14.3. Each bearing part 14.1, 14.2 further defines an axially extending cross-sectionally part circular, preferably generally semi-circular, inner surface 14.4. When in a mouiited condition on the mount 112, the inner surfaces 14.4 together define the passage 16 through which the elongate component 17 can extend.
7 Referring now to Figure 5 of the drawings, in which like reference numerals have been used to designate similar parts, unless otherwise stated, another bearing assembly in accordance with the invention, is generally indicated by reference numeral 210. The bearing assembly 210 is similar to the bearing assembly 110, save that the bearing 114 of the assembly 210 has two parts 114.1, 114.2 each part being elongate and defining a collar formation 114.3, 114.4 projecting radially outwardly from each end 114.5, 114.6.
The collar formations 114.3, 114.4 serve to hold the bearing parts, or inserts, 114.1, 114.2 captive on the bearing mount 112 when in a mounted condition.
It will be appreciated that by providing the mount 12, 112 and the bearing 14, in split form, the assemblies 10, 110, 210 can be disassembled and assembled around an elongate component, such as the component 17, without having to thread the component through an aperture such as the passage 16. In certain cases, such as where the elongate element, or guidance system, is fixed as in the case of a rail like elongate element as opposed to flexible as in the case of a rope-like elongate element, the bearing assembly of the invention need not necessarily surround the whole circumference of the elongate element, but can be arranged to extend around the elongate element by a sufficient amount to inhibit the elongate element form escaping laterally. Accordingly, the bearing assembly can be arranged to extend around the elongate element for about 270 , or the like.
