Description
Technical field
The utility model belongs to axle sleeve field, and in particular to a kind of shaft sleeve device for preventing axial float.
Background technique
Axle sleeve is widely used in the occasion that revolving speed is lower, clearance requirement is relatively high to replace rolling bearing, especially extensively
General use is in the hinged place of the equipment structural member of engineering machinery.Axle sleeve in use by uneven mechanical oscillation, rub
Axial play can occur for the influence of power of the effects of wiping, and the effect of hinged place revolving support will be greatly reduced after generation play.For
The existing deficiency of improvement, some technologies prevent axle sleeve from axially sliding by the way that one section of screw thread is arranged in the outer ring of axle sleeve, still
Structure is complicated for the structure type, manufacturing cost is high；Some technologies use T-type axle sleeve, but the structure type can only prevent one
The play in direction, the play of opposite direction need other auxiliary spare parts such as end cap to be positioned, and manufacturing cost is higher.
Utility model content
The purpose of the present invention is to provide a kind of shaft sleeve device for preventing axial float, which uses simple, system
Make axial float at low cost, and that axle sleeve can be effectively prevented.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of shaft sleeve device preventing axial float, including axle sleeve and with axle sleeve termination flange, the flange it is interior
Diameter is identical as the internal diameter of the axle sleeve, and through-thickness is provided on the flange through flange for the shaft sleeve device
Carry out the locating notch of axially position.
As the further preferred of the utility model, the locating notch is set as multiple, multiple locating notch edges
The circumferential direction of the flange is uniformly or non-uniformly distributed on the flange.
As the further preferred of the utility model, the locating notch is gap opened or closed notch.
As the further preferred of the utility model, the locating notch is half slotted hole locating notch, tapered positioning lacks
Mouth or arch locating notch.
As the further preferred of the utility model, the half slotted hole locating notch and arch locating notch are open
Notch；The tapered locating notch is closed notch.
When installation, the shaft sleeve device realizes axially position by carrying out spot welding on locating notch.When disassembly, the axis
Covering device is by falling into capable dismounting for the weld seam planing in locating notch.
As the further preferred of the utility model, the shaft sleeve device is real by the cooperation of bolt and nut and locating notch
Existing axially position.
Compared with the prior art, the utility model has following advantageous effects: the axial direction for effectively preventing axle sleeve is altered
It is dynamic, it is easy to use, structure is simple, manufacturing cost is low, and also positioning method is simple, and locating effect is obvious.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the shaft sleeve device with half slotted hole locating notch of an embodiment of the present invention；
Fig. 2 is the structural schematic diagram of the shaft sleeve device with tapered locating notch of another embodiment of the utility model；
Fig. 3 is the structural schematic diagram of the shaft sleeve device with arch locating notch of another embodiment of the utility model.
Wherein: 1 axle sleeve；2 flange；3 locating notches；Half slotted hole locating notch of 3-1；The tapered locating notch of 3-2；3-3 arch
Shape locating notch.
Specific embodiment
The utility model is further described combined with specific embodiments below.Following embodiment is only used for clearly
Illustrate the technical solution of the utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1-3, a kind of shaft sleeve device for preventing axial float of the utility model, including axle sleeve 1, flange 2 with
And locating notch 3.The flange 2 is terminated with axle sleeve 1, and the internal diameter of the flange 2 is identical as the internal diameter of the axle sleeve 1.It is described fixed
Position notch 3 is arranged on flange 2, for carrying out axially position to the shaft sleeve device.
Wherein, the number of locating notch 3 is not limited to one, can be two or more along the circumferential direction of flange 2
It is distributed on flange 2.The distribution mode, which can be, is uniformly also possible to uneven distribution.
A variety of designs can be used in the structure type of locating notch 3, for example, it may be half slotted hole positioning as shown in Figure 1
Notch 3-1, the slotted hole locating notch 3-1 use Open architecture；It is also possible to tapered locating notch 3-2 as shown in Figure 2,
The tapered locating notch 3-2 uses enclosed construction；It can also be arch locating notch 3-3 as shown in Figure 3, arch positioning
Notch 3-3 is Open architecture.The structure type of the locating notch 3 is not limited to three of the above, and shape can be more
Kind form, the structure type is the preferred embodiment of multiple structural forms.
When carrying out axially position using locating notch 3, can be fixed using welding manner.Specifically, axle sleeve 1 is pressed into
Hinge hole, after flange 2 is bonded rack close to the one side of axle sleeve 1, on electric welding machine locating notch 3 reserved on flange 2
Carry out spot welding positioning.Wherein, the work operating condition different according to axle sleeve 1 can uniformly or non-uniformly be distributed two in the circumferential direction of flange 2
A and more than two locating notches 3.
Abrasion can occur after long-term use and scrap for axle sleeve 1, need to dismantle on axle sleeve 1.Need to only it use gouge machine will when disassembly
Weld seam planing in locating notch 3 is fallen.
