Description
Technical field
The utility model belongs to is used cooperatively component technology field with hydraulic motor, and in particular to one kind is used for dextrorotation circular cone
Axis stretches the axle sleeve structure of hydraulic motor.
Background technology
Axle sleeve is machinery industry connection power output (hydraulic motor, motor, retarder, engine, gearbox etc.) axis
With the transition member between acting component (flabellum, water pump vane, flying wheel etc.).
Hydraulic motor is stretched for from the dextrorotation cone axis of external import, the external screw thread and clamp nut that axis is stretched are dextrorotation spiral shell
Line pair, when driving flabellum, there is following two aspects in conventional bushings：First, flabellum is when starting, working, brake
Turning moment, there is clamp nut loosening, common locking arrange can not be taken due to the radial dimension of limitation of axle sleeve
It applies.Secondth, the axis of cone is stretched coordinates with taper hole, and axial position change is big, and axle sleeve left end is it is possible that encounter hydraulic motor non-rotating
Part makes axle sleeve generate friction with hydraulic motor non-rotating part, causes to generate heat, reduce mechanical efficiency, even make driving hydraulic pressure
The hydraulic pump of motor can not work, and hydraulic motor and flabellum basic function is caused to be lost.
Utility model content
The purpose of the utility model is to overcome in the prior art the defects of, and for from the dextrorotation cone axis of external import
Hydraulic motor is stretched a kind of simple in structure, reasonable design is provided and clamp nut can be effectively prevent to loosen and effectively prevent non-rotation
Transfer part point and the axle sleeve structure that hydraulic motor is stretched for dextrorotation cone axis of axle sleeve friction.
The purpose of this utility model is achieved like this：Main shaft including hydraulic motor, the outside of main shaft is taper shaft
Stretch end, the hydraulic motor end face on the outside of main shaft is equipped with hydraulic motor seam allowance, the external peripheral surface of the taper axle stretch end end
Dextrorotation external screw thread is offered, the dextrorotation external screw thread of taper axle stretch end end passes through the dextrorotation fastening in the hole and axle sleeve of axle sleeve one end
Nut is adapted, and offers levogyrate inner thread in another stomidium of axle sleeve, and the levogyrate inner thread in hole is left-handed in hole with being sleeved on
Locking thread nut is adapted；The outside of described axle sleeve one end is equipped with axle journal boss, and the outer diameter of axle journal boss is less than hydraulic motor
The outer diameter of main shaft, the length of axle journal boss are more than the depth of hydraulic motor seam allowance.
Preferably, it is provided with washer between the hole of described axle sleeve one end and clamp nut.
Preferably, the side excircle of the left hand thread stop nut is adapted with the levogyrate inner thread in hole, left-handed
The distance between the end side of locking thread nut and clamp nut are not more than 0.1mm.
The utility model has simple in structure, reasonable design, clamp nut loosening and hydraulic motor can be effectively prevent to stop
Mouth bottom surface and axle sleeve friction, the advantages of generating heat, reduce mechanical efficiency and can not start.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In order to which the technical features, objects and effects to utility model are more clearly understood, now control illustrates this
The specific embodiment of utility model, in the various figures identical label represent identical component.To make simplified form, in each figure
Only schematically show with the relevant part of the utility model, they do not represent its practical structures as product.
As shown in Figure 1, the utility model is a kind of axle sleeve structure that hydraulic motor is stretched for dextrorotation cone axis, including hydraulic pressure
The main shaft 9 of motor 1, the outside of main shaft 9 is taper axle stretch end 2, and 1 end face of hydraulic motor in 9 outside of main shaft is equipped with hydraulic motor
Seam allowance 3, the external peripheral surface of 2 end of taper axle stretch end offer dextrorotation external screw thread, outside the dextrorotation of 2 end of taper axle stretch end
The hole for being thread through 4 one end of axle sleeve is adapted with the dextrorotation clamp nut 6 in axle sleeve 4, is offered in 4 another stomidium of axle sleeve left-handed
Internal thread, the levogyrate inner thread in hole are adapted with the left hand thread stop nut 7 being sleeved in hole；Described 4 one end of axle sleeve
Outside is equipped with axle journal boss 8, and the outer diameter of axle journal boss 8 is less than the outer diameter of hydraulic motor main shaft 9, and the length of axle journal boss 8 is more than
The depth of hydraulic motor seam allowance 3.Washer 5 is provided between the hole of described 4 one end of axle sleeve and clamp nut 6.The left hand thread
The side excircle of stop nut 7 is adapted with the levogyrate inner thread in hole, the end side of left hand thread stop nut 7 with
The distance between clamp nut 6 is not more than 0.1mm.
When the axis that the axis of cone stretches hydraulic motor 1 is stretched when upper screw thread, clamp nut and motor rotation direction are dextrorotation this reality can be used
With novel, the utility model is sleeved on the outside of the 9 taper axle stretch end 2 of main shaft of hydraulic motor 1 by when use, makes taper axle stretch end
2 end passes through the hole of 4 one end of axle sleeve, and in the end mounting gasket 5 of taper axle stretch end 2 and dextrorotation clamp nut 6, axle sleeve 4
Levogyrate inner thread is offered in another stomidium, the left hand thread stop nut 7 of non-national standard is sleeved in 4 other end of axle sleeve
Portion, and left hand thread stop nut 7 is made to be meshed with levogyrate inner thread, the end side of left hand thread stop nut 7 can be with
Certain interval can also be had between clamp nut 6 by compressing clamp nut 6, excellent to achieve the purpose that prevent clamp nut 6 from loosening
Selection of land, above-mentioned gap are not more than 0.1mm；By taking electric fan as an example, 1 propeller shaft sleeve 4 of hydraulic motor drives electric fan dextrorotation, when
Electric fan start, work when, braking when, by above structure can effectively prevent the situation loosened by inertia occur.Together
When, the outside of 4 one end of axle sleeve is equipped with axle journal boss 8, and the outer diameter of axle journal boss 8 is less than the outer diameter of hydraulic motor main shaft 9, due to it
Outer diameter be less than main shaft 9 outer diameter, so the outer diameter of axle journal boss 8 be smaller than it is straight at 1 hydraulic motor axle stretch end lid of hydraulic motor
Diameter, and the length of axle journal boss 8 is more than the depth of hydraulic motor seam allowance 3, by designing above structure, even if assembling or axle sleeve 4
When being subjected to displacement, the end of axle journal boss 8 can only will not be sent out with 9 joint of motor spindle, axle sleeve 4 with the shell of hydraulic motor 1
Raw contact, and motor spindle 9 rotates together with axle journal boss 8, therefore will not generate friction, generates heat, reduces mechanical efficiency, even
The defects of can not starting.It should be noted that the hydraulic motor seam allowance 3 described in the utility model is arranged on hydraulic motor 1
It is non-rotating part on end face.
The a series of tool that the feasibility embodiment only for the utility model is described in detail of those listed above
Body illustrates, they are all to be made without departing from the utility model skill spirit not to limit the scope of protection of the utility model
Equivalent implementations or change should be included within the scope of protection of this utility model.
