Incorporated by reference to Fig. 1 and Fig. 2, the wheel group 10 of the hoisting crane of an embodiment comprises axletree 100, wheel 200, bearing 300, axle spacer 400, axle end baffle plate 500 and connecting element 600.
One end of axletree 100 is provided with block wall 110, and middle part is stepped shaft structure 120, and the other end is provided with draw-in groove 102.In the present embodiment, the part that the mid diameter of stepped shaft structure 120 is larger is wheel mounting portion, and two ends are axle bearing mount portion.To be part arranged around the end of axletree 100 draw-in groove 102.
The periphery of wheel 200 is provided with race 202.The middle part of wheel 200 is provided with the wheel shaft mounting hole and bearing mounting hole (not indicating in figure) that axially run through.The internal diameter of wheel shaft mounting hole and the larger external diameter (i.e. wheel mounting portion) of stepped shaft structure suitable and be less than the internal diameter of bearing mounting hole.Bearing mounting hole is positioned at the both sides of wheel shaft mounting hole and is communicated with wheel shaft mounting hole.Wheel 200 is set on axletree 100 and the larger part of the diameter of this stepped shaft structure is positioned at wheel shaft mounting hole.
Wheel 200 is overall tooth-like adhesion wheel, and namely at least one side channel wall of race 202 is gear structure 210.The thickness of the cell wall of this gear structure 210 is greater than the thickness of opposite side cell wall, can ensure power transmission precision, and then improves power transmission stability.As shown in Figure 3 and Figure 4, in other embodiments, this wheel 200 also can be fixed shaft type by motor car wheel, this by the both sides cell wall thickness of the race 202 of motor car wheel, highly consistent, and does not have gear structure.
The bearing 300 of present embodiment is the deep groove ball bearing of band cover of dust.Bearing 300 carries cover of dust, and can avoid needs to load other dust-proof member when mounted, thus simplifies kind and the quantity of parts, makes integral structure more compact, and simplifies fitting operation, be convenient to equipment detachable maintaining.Bearing 300 has two, to be set in respectively on axletree 100 and to be positioned at bearing mounting hole, and wherein a bearing 300 abuts against with block wall 110.
Axle spacer 400 is set on axletree 100, and one end and another bearing 300 abut against.In the present embodiment, this gear structure 210 is located on the side cell wall of race 202, the cell wall of the race 202 specifically near axle spacer 400 side.
Axle end baffle plate 500 part is stuck in draw-in groove 102.Axle end baffle plate 500 abuts against with the other end of axle spacer 400, and is fixed in the end carriage (not shown) of hoisting crane by connecting element 600.
The connecting element 600 of present embodiment is bolt assembly.Connecting element 600 comprises bolt and packing ring (not indicating in figure).Wheel 200 is provided with the screw (not shown) suitable with bolt.In the present embodiment, corresponding each wheel 200, connecting element 600 has two groups, and each axle end baffle plate 500 is fixed on corresponding end carriage by two groups of connecting elements 600.
This wheel group 10 can be widely used in hoisting crane, as crane in bridge type, and gauntry crane etc.
In the present embodiment, the corresponding each wheel 200 of this wheel group 10, only need axletree 100, two pieces band cover of dust deep groove ball bearing 300, axle spacer 400, axle end baffle plate 500 and two groups of connecting elements 600 (i.e. two groups of bolts and packing ring), thus this wheel group 10 only needs 10 parts just can assemble, and structure is simple.Than traditional car wheel group structure, parts kind, specification and the quantity needed for wheel group of present embodiment want much less, and processing and fabricating is simple, and easily, production efficiency significantly improves in assembling.This wheel group 10 is steadily stablized when transmission, there will not be traditional gear bolt to connect split or wheel work of a specified duration after the loosening problem that occurs, and the compact conformation of wheel group, low-profile.Bearing 300 with cover of dust simplifies kind and the quantity of parts, make wheel group 10 structure more compact, effectively reduce the assembling width of wheel group 10, reach the object of the end carriage weight reducing matched, loop wheel machine monnolithic case size is reduced, overall weight also mitigates, and effectively reduces costs and reduces energy consumption with saving resource.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this specification sheets is recorded.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
