Description

Quick-release hub, roller and roller cage shoe

Technical Field

The invention relates to a wheel hub for a roller cage shoe, and also relates to a roller with the wheel hub and a roller cage shoe with the roller.

Background

The roller cage shoe is generally arranged on the cage for guiding the cage, the conventional structure of the roller cage shoe can be seen in pages 1-4 of a coal industry standard MT236-2011 (the standard name is a rectangular steel cage shoe roller cage shoe), the conventional structure of the roller cage shoe comprises a bottom frame, a swinging arm with one end arranged on the bottom frame through a hinge shaft, one end of the swinging arm is connected with one end of a buffer through the hinge shaft, the other end of the buffer is connected on the bottom frame through the hinge shaft, and the roller is arranged on the swinging arm. The cushioning effect of the bumpers is relatively low on the cushioning effect of the rollers themselves, although it is common to use relatively thick outer wheels (typically polyurethane or rubber). The basic structure of the roller cage is not limited thereto, and in some implementations, the undercarriage has a vertical frame body that is generally parallel to the swing arm, and a resilient assembly, such as a spring guide post assembly, is disposed between the swing arm and the vertical prosthesis.

In general, hubs of rollers used for roller cage shoes all comprise 2-3 hub bodies, for example, chinese patent document CN201043106Y discloses a light roller cage shoe, wherein the hub bodies adopt a left-right structure or a left-middle-right structure, the left-right structure is formed by assembling a first main support body-a first auxiliary support body through bolts, and the left-middle-right structure is formed by assembling a first auxiliary support body-a first main support body and a second auxiliary support body through bolts. When the hub is detached, all bolts are required to be loosened first, and since nuts are required to be arranged at one end opposite to the bolt heads, the wrench is required to be arranged at the two ends of the hub, the detachment is difficult, and when the first auxiliary supporting body is detached, for example, the second auxiliary supporting body at the other end can lose constraint.

In recent years, a number of roller cage ears for convenient maintenance are presented, such as chinese patent document CN207111696U, in which the hub is mainly assembled from an inner ring and left and right outer rings, the outer rings are used for mounting the rubber rim, and when the single-side outer ring is removed, the rubber rim can be removed, so that the maintenance is relatively convenient. However, the left and right outer rings still have to be connected by bolts, and when one outer ring is detached, the other outer ring also loses constraint, and when the other outer ring is detached, a spanner is also required to be simultaneously detached from both ends of the roller.

Chinese patent document CN207161514U discloses a readily removable roller hub, which has a rubber groove on its outer periphery, and which has a bearing housing, a radial connector fixedly connected to the bearing housing at its centripetal end, a support sleeve fixedly connected to the centrifugal end of the radial connector, and two annular end plates and two cone sleeves. The easily-detached roller hub divides the hub into smaller units, and has better casting manufacturability, but the assembly difficulty is relatively higher because of more pieces. Although the bolts are used for fixing the end plate on the bearing seat or other relatively fixed structures, the outer wheel can be replaced by removing the end plate and the taper sleeve at one end, the number of the disassembly is relatively large, and the later maintenance is relatively troublesome.

Detailed Description

Referring to fig. 1 of the drawings, the axle 17 is referred to in the drawings, and it will be understood that the left and right ends of the axle 17 face inward and face outward.

In the embodiment shown in fig. 1 and 6, the rollers are mounted on the axle 17 by means of a pair of tapered roller bearings 6, the bearing housing 29 provided by the main hub 3 being a basic frame of reference, hereinafter, with respect to the axial, circumferential or radial direction, based on the bearing housing 29 unless specifically stated.

In some implementations in the field of roller shoes, bearings are mounted on the swivel arm for the dynamic connection of the axle 7 to the swivel arm. If the bearing is mounted in the bearing chamber 24 shown in fig. 2, the connection between the axle 7 and the pendulum arm is a static connection. In the embodiment of the present invention, the bearing housing 23 is used to represent the fitting structure between the hub and the axle 7, and not necessarily to represent the structure that provides the bearing chamber 24. In the embodiments of the present invention, the term name is mainly used to name related technical features, and does not mean that they necessarily have a corresponding structure.

The roller is mounted on the roller cage in two main ways, one of which is shown in fig. 1, namely, the right end of the wheel shaft 17 is fixedly mounted on the swing arm of the roller cage.

In some implementations, the hub is integral with the axle 17, or the axle is in static connection with the hub, in which case the axle 17 is in dynamic connection with the pendulum arm via bearings.

Referring to fig. 1 and 6 of the drawings, it can be seen that the hub provided on the roller mainly comprises two parts, one being a main hub 3 and the other being a secondary hub 2, which are connected together by a plurality of screws 9, wherein the secondary hub 2 alone provides the mounting base rim 23 of the outer wheel 1.

In general, the outer wheel 1 of the roller for the roller cage ear adopts a polyurethane rubber wheel, the hub needs to provide a rubber wheel groove for installing the polyurethane rubber wheel, and the polyurethane has a certain hardness, for example, the hardness is between shore a10 and shore D75, so that the outer wheel 1 is required to be assembled and disassembled in the rubber wheel groove, the restraint of the rim of the hub on the outer wheel 1 in the axial direction of the roller is required to be removed, and the outer wheel 1 is difficult to be disassembled from a single side of the roller.

In the structure shown in fig. 3, the base rim 23 formed at the radial end of the secondary hub 2 provides support for the independent outer wheel 1, and the outer wheel 1 is formed on the base rim 23 based on an encapsulation process without additional constraint of the rim, and the outer wheel 1 formed thereby is denoted as an encapsulated outer wheel, and the material used is the same as that of the existing outer wheel 1, preferably polyurethane.

The thickness of the rubber-coated outer wheel is far smaller than that of the outer wheel 1 based on the rubber wheel groove, and the material consumption is relatively lower.

Furthermore, since the outer wheel 1 can be removed together with the sub-hub 1, replacement is relatively easy.

Referring to the main hub 3, and referring to figures 4 and 5 of the drawings, it can be seen that it has a bearing seat 29 and a main web extending radially from the bearing seat 29, the main web may be replaced by a main web, the main web may be provided with lightening holes, and the lightening spaces may be defined between adjacent main webs.

As mentioned above, the bearing housing 29 is only used to represent the structure on the hub for assembly with the axle 17 in the embodiments of the present invention, and the connection between the bearing housing 29 and the axle 17 may be a dynamic connection or a static connection, with the difference that the assembly positions of the bearings are slightly different.

As shown in fig. 1 and 5, the bearing housing 29 provides a bearing chamber 28, and a pair of tapered roller bearings 6 are mounted in the bearing chamber 28 for mounting the hub on the axle 17. If the hub and the axle 17 form an integral shaft or are welded to the axle 17, the right end of the axle 17 may be mounted on the swing arm of the roller cage through a bearing.

The arrangement of the bearings on the swing arms is more suitable in the implementation of the two-end support axle 17 shown in fig. 6.

It will be appreciated that the main web or spokes on the main hub 3, whether radially extending or not, are intended to provide the base rim 23 with a defined diameter, and thus, for example, the main web may have a certain extent in the axial direction of the roller, and for integral hubs, such as the main web, the outer or centrifugal end thereof typically has a rim. In an embodiment of the invention, a support rim or support fanning ring is formed at the centrifugal end of the main web or main spoke.

Wherein, the support fan ring is mainly matched with the main wheel pair.

Regarding the sub-hub 2, see fig. 1, 3 and 6 of the specification, the sub-hub 2 is integrally supported on the main hub 3 and serves to support the outer wheel 1. For the secondary hub 2, the illustrated construction can be seen in fig. 2 and 3, the secondary hub 2 having a hub sleeve which is nested and supported on a bearing seat 29, as in the portion of fig. 3 having the first countersink 21.

It should be noted that for a roller, the geometry defined by its axis is generally referred to as the width, whereas for a wheel, such as a spoke or web, the width is often less than the width (or axial length) of the hub (such as bearing seat 29) and less than the width of the rim, so it will be appreciated that, for example, a spoke, when attached to the hub, does not occupy the entire hub width, and the remainder may serve as a support for the hub of the secondary hub 2.

Further, the sub-hub 2 has a sub-web or sub-web extending radially from the hub sleeve, and the sub-hub 2 and the main hub 3 are each formed of one piece, so that the sub-web and the main web are juxtaposed in a position, for example, between them, as shown in fig. 1 and 2.

As described above, the rim for supporting the outer wheel 1 is provided by the sub-hub 2, and therefore, the base rim 23 is formed at the centrifugal end of the sub-spoke or sub-spoke, the centrifugal side of the base rim 23 is contoured as a cylindrical surface, the centripetal side has the second tapered surface 24 shown in fig. 3 in addition to the portion for connecting with the sub-spoke or sub-spoke, and the centripetal side of the base rim 23, such as the portion where the second tapered surface 24 is located, is supported at the centrifugal side of the main hub 3, i.e., the support rim or support fan ring. The portion of the base rim 23 for cooperation with the support rim or support fan ring is denoted as the second portion.

The portion of the secondary hub axially opposite the second portion is denoted as a first portion which is recessed to reduce the weight of the secondary hub itself and to enhance the casting manufacturability.

The spokes and the spokes belong to radial connectors, so that the main spokes or the main wheel pair are approximately parallel to the auxiliary spokes or the auxiliary spokes, and screw holes 22 are formed in the auxiliary spokes as shown in fig. 3, while in the structure shown in fig. 5, screw holes 34 are formed in positions, and then the main spokes or the main spokes and the auxiliary spokes or the auxiliary spokes are connected by the screws 9 in cooperation with spring washers (short for elastic washers).

When the screw 9 is used for connection, the convenience of assembly and disassembly is better, and the spanner can be arranged from one end instead of the spanner at two ends like a bolt.

In particular, as shown in fig. 1, if the sub-hub 2 is detached from the left end, the sub-hub 2 can be detached from the main hub 3 only by detaching the screws 9.

In the configuration shown in fig. 5, for example, a cone 33 forming a support rim or support fanning ring, is cantilevered toward the second end in the axial direction of the bearing housing 29 to provide a relatively large bearing surface area, such as the area of the second outer conical surface 32, that is relatively large and does not interfere with the secondary spokes or webs.

Accordingly, the first portion of bearing housing 29, which engages the hub, is located on a first side of the primary web or spoke, opposite the side on which the second end is located, so that interference between the secondary web or spoke and, for example, cone 33, can be avoided.

In the foregoing it was pointed out that the use of screws 9 for the connection between the main hub 3 and the secondary hub 2 may in some implementations improve the removability or maintainability of the hub or the roller in that its maintenance is mainly reflected in the replacement of the outer wheel 1. As shown in fig. 1, the axle 17 corresponding to the bearing seat 29 is supported by a single end, that is, the right end of the axle 17 in fig. 1, and the secondary hub 2 carrying the outer wheel 1 can be detached from the left end shown in fig. 1, because the fastening is realized by the screws 9, the detachment can be performed simply by the left end of the roller, and the detachment efficiency is relatively high because only six screws 9 and the matched elastic pad 10 are required besides the secondary hub 2.

Further, if the axle 17 corresponding to the bearing housing 29 is supported by a single end, the supporting end of the axle 17 is the second end, as shown in the right end of fig. 1.

In the structure shown in fig. 6, the wheel shafts 17 are supported at both ends, and if the sub-hub 2 is to be removed, the roller is removed as a whole, and then the sub-hub 2 is removed from the left end.

In the structure shown in fig. 6, the screws 9 may be used for the assembly between the main hub 3 and the sub-hub 2, or bolts may be used for the assembly of both.

As described above, in order to enhance the reliability of the overall assembly, the hub sleeve of the sub-hub 2 needs to be fitted over the bearing housing 29, and further, the main spokes or the main web are offset toward the second end in the axial direction of the bearing housing 29, and the portion of the hub sleeve that engages with the bearing housing 29 is located on the first end side of the main wheel set, so that the hub sleeve can have a relatively large width when the main wheel set or the main web is offset toward the second end in the axial direction of the bearing housing 29.

In the construction shown in fig. 1, the displacement of the primary wheel set to the right is relatively pronounced, and in fig. 6, the displacement of the primary wheel set to the right is relatively small due to the relatively wide bearing housing 29.

If the axle 17 corresponding to the bearing seat 29 is supported by a single end, as shown in fig. 1, the second end surface of the supporting rim or the supporting fan ring is coplanar with the second end surface of the base rim 23.

If the axle 17 corresponding to the bearing seat 29 is supported at both ends, as shown in fig. 6, the second end surface of the supporting rim or the supporting fan ring is located inside the second end surface of the base rim 23.

Unlike conventional roller cage rollers, in the roller of fig. 1 and 6, the outer wheel 1 is independently supported by the secondary hub 2, and two supporting surfaces exist between the secondary hub 2 and the main hub 3, one of which is provided with a bearing housing 29, and the other of which is provided with a cone 35 shown in fig. 5. The two supporting surfaces of the main hub 3 for supporting the sub-hub 2 may have the following problems, affected by the machining precision:

if both support surfaces of the main hub 3 for supporting the sub hub 2 are cylindrical surfaces, it is possible that only one cylindrical surface can play a supporting role, and a gap exists between the other cylindrical surface and the surface to be supported.

Thus, in a preferred embodiment, the engagement of the hub with the bearing seat 29 is a first cone of taper and the engagement of the second portion with the support rim or support fan ring is a second cone of taper, in particular the first cone 21 forms a first cone of taper with the seat of the bearing seat 29 and the second cone 26 forms a second cone of taper with the cone 33.

One necessary condition for meeting the reliable matching of the auxiliary hub 2 and the main hub 3 is that the first taper of the first taper hole cone is the same as the second taper of the second taper hole cone, and the taper hole matching is based on extrusion, so that the problem of assembly interference caused by machining precision can be effectively eliminated or reduced.

In addition, based on taper hole cone cooperation, through the pretension of screw 9, can form reliable interference fit, assembly reliability is higher.

Preferably, the first taper and the second taper are 1 or more: 24-1:6, wherein the minimum taper is also ensured that the friction angle of the cone taper hole matching is larger than the pressure angle, and the maximum taper is influenced by the maximum axial movement amount during assembly.

Further, as shown in fig. 1 and 6, a gap is left between the main web or the main spoke and the auxiliary web or the auxiliary spoke, and the gap belongs to a design gap, so that on one hand, the reliability of assembly is ensured, and on the other hand, the space between the main web or the main wheel pair and the auxiliary web or the auxiliary spoke is relatively large, so that the rigidity of the hub is relatively high.

Further, the gap is positively correlated with the first taper, i.e., the greater the taper, the greater the gap. It should be noted that, regarding the taper, the size is not easily distinguished in some people's understanding, and here, the smaller the numerical value is, the larger the taper is, based on, for example, a numerical value corresponding to d/h. Wherein d represents the bottom side length of the equivalent isosceles triangle corresponding to the cone, and h represents the height corresponding to the bottom side of the isosceles triangle.

The wheel hub is provided with an outer wheel 1, an axle 17 and a component for assembling the wheel hub and the axle 17, namely, a roller is formed, the roller is arranged on a swinging arm of a roller cage, the swinging arm is hinged to a bottom frame, the swinging arm is approximately L-shaped, the roller is usually arranged at a corner of the L-shaped structure, the other end of the swinging arm is hinged to one end of a buffer, the other end of the buffer is hinged to the bottom frame, the buffer is generally vertical to the bottom frame, the bottom frame is used for mounting the roller cage at the upper end or the lower end of a cage for a vertical shaft, and the supporting wheel is provided with an outer wheel formed based on a rubber coating process.

If the wheel axle 17 of the roller is supported by a single end, as shown in fig. 1, the oil seal cover 18 is mounted on the same end of the bearing seat 29 as the supporting end of the wheel axle 17, and the end cover 8 is mounted on the opposite end of the supporting end of the wheel axle 17.

If the wheel shafts 17 of the rollers are supported at both ends, both ends of the bearing chamber 28 are fitted with oil covers 18.

The end cap 8 is mounted on the bearing seat 29 by the screw 4, and as it is a static seal, the assembly requirements are relatively low, and a sealing element, such as a sealing gasket, can be added to the joint surface of the end cap 8 and the bearing seat 29.

In fig. 1, the end cap 8 is provided with an oil filling hole, and correspondingly, the right end of the axle 17 is provided with an oil passage aligned with the oil filling hole, and the outlet end of the oil passage is aligned with the middle position of the bearing seat 29 at the side surface of the axle.

Accordingly, the oil filling hole is provided with an oil plug.

For the oil seal cover 18, the seal between the oil seal cover 18 and the bearing seat 29 belongs to static seal, the seal between the oil seal cover and the wheel axle 17 belongs to dynamic seal, and in order to ensure that the dynamic seal has better sealing capability, the part of the oil seal cover 18 assembled with the bearing seat 29 as a whole is a flange, the flange extends outwards to form a pipe sleeve, a gap is reserved between the pipe sleeve and the wheel axle 17, and the pipe sleeve and the wheel axle are dynamic and static.

Further, a sub-cap 16 is provided, the sub-cap 16 having a cylindrical structure with a central hole, wherein a tub is coaxially sleeved outside the socket, and an inner diameter of the tub is larger than an outer diameter of the socket, so that a sealed space is formed between the tub and the socket.

Further, the central hole is in interference fit with the axle 17, which is also called interference connection, in other words, the auxiliary cover 16 is integrally connected with the axle 17, and there is relative movement with the oil seal cover 18, so that a clearance for avoiding movement is required to be left between the end face of the barrel body of the auxiliary cover 16 and the oil seal cover 18.

Further, a double lip seal 15 is provided in the sealed space defined between the tub and the axle 17.

In fig. 1 and 6, two double-lip seal rings 15 are arranged in one auxiliary cover 16, a spacer bush is arranged between the two double-lip seal rings 15, the spacer bush is in interference fit with the pipe sleeve, and the sealing space is configured into a labyrinth structure.

In some embodiments, the center of the oil cover 18 may have an axial length that forms a sleeve within which a seal ring is disposed or a skeletal oil seal is disposed.

In addition, the main hub 3 and the sub-hub 2 in fig. 1 and 6 are not complicated in overall structure from the viewpoint of casting manufacturability, and meet the casting manufacturability requirements.

The main hub 3 and the auxiliary hub 2 are mainly made of cast aluminum, and have high strength and small overall weight.

In some implementations, the primary and secondary hubs 3, 2 are formed from wrought aluminum alloy.
