Description
Technical field
This utility model relates to bearing assembly or disassembly aid technical field, refers specifically to a kind of bearing dismounting tool.
Background technology
At machinery industry, bearing is by the vitals of the transmission of power, residing work under bad environment, especially metallurgical,
Mining and shipping industry, the running requirements to machinery equipment is higher, and in the transmission process of machinery, bearing block is in high temperature, punching
Hit, in the harsh environments of high dust.After bearing assembling, if finding, existence assembling defect or periodic maintenance maintenance are changed
Time, needing to unload bearing down, traditional way is to pound out from bearing pilot hole the most bit by bit, this operation
Method is cumbersome, wastes time and energy, not only inefficiency, can cause the damage of bearing toward contact, especially needs dismounting many
When planting the bearing of different size, even with more existing aids, it is also difficult to reach the purpose of fast quick-detach, existing
Aid can not adapt to the bearing of multiple different size, adjusts process complicated, wastes time and energy, and work efficiency is low, needs badly
Solve.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of bearing dismounting tool.
For solving the problems referred to above, this utility model offer techniques below scheme:
A kind of bearing dismounting tool, including the frock head that the body of rod of hollow-core construction and body of rod two ends specification are different；Described frock head
Including cutting ferrule；The draw-in groove mated with required dismounting bearing outside diameter it is provided with, away from the one of the described body of rod on card set inside described cutting ferrule
End is provided with holding screw, is provided with screwed hole near one end of the described body of rod, and cutting ferrule can by the fixing screw being screwed in screwed hole
Being connected on the body of rod of dismounting；Described holding screw is along the described uniform setting of body of rod circumferencial direction.
Further, the wall thickness of the described body of rod is 5mm-10mm.
Further, described cutting ferrule and the body of rod all use spring steel to make.
Further, described cutting ferrule is provided with lead-in chamfered away from the opening part of one end of the described body of rod.
Further, the described body of rod is provided with and several runs through through hole.
Further, the described body of rod is length-adjustable Telescopic shaft type structure.
Further, described cutting ferrule inwall is provided with Nitinol wearing course.
Beneficial effect: this utility model structure designs, and can match different size of frock head according to the bearing of different size,
Therefore, it is possible to be applicable to the dismounting of different size bearing, easy to use, time saving and energy saving, it is effectively increased the work of dismounting bearing
Efficiency.Cutting ferrule inwall is provided with Nitinol wearing course, and cutting ferrule wearability is good, and permanent use is unlikely to deform, the most easy to wear.Further,
According to actual needs the length of the body of rod can be made accommodation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the 1-body of rod；2-cutting ferrule；3-holding screw；4-fixes screw；5-runs through through hole；6-guiding surface.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
A kind of bearing dismounting tool, as it is shown in figure 1, include the body of rod 1 of hollow-core construction and the work that the body of rod 1 two ends specification is different
Dress head；Described frock head includes cutting ferrule 2；Described cutting ferrule 2 is internal is provided with the draw-in groove mated with required dismounting bearing outside diameter, at card
On set 2, the one end away from the described body of rod 1 is provided with some holding screws 3, is provided with screwed hole near one end of the described body of rod 1, card
Set 2 is removably attachable on the body of rod 1 by the fixing screw 4 being screwed in screwed hole.It should be noted that on the body of rod 1
Holding screw 3 along the uniform setting of body of rod circumferencial direction, and at least 3, when making fastening bearing, exert a force more stable reliably,
It is readily disassembled.
It is pointed out that the wall thickness of the above-mentioned body of rod 1 is preferably 5mm-10mm, the body of rod in this wall thickness range, both met
The force request when body of rod 1 uses, the most also effectively reduces the use of metal material, and low cost is lightweight, good portability.
Wherein, described cutting ferrule 2 and the body of rod all use spring steel to make, and tensile strength is good, and fatigue strength is high, in dismounting bearing mistake
Cheng Zhong, will not fracture.
Wherein, described cutting ferrule 2 is provided with lead-in chamfered 6 away from the opening part of one end of the described body of rod, in the guiding of guiding surface 6
Under effect, bearing can be relatively easy to be inserted in cutting ferrule 2, and disassembling section is easy, time saving and energy saving, and efficiency is high.
Wherein, the described body of rod 1 is provided with and several runs through through hole 5, can iron staff or spanner etc. be inserted through in through hole, as
Boosting-rod is used, it is easy to dismounting, the most laborsaving.
In order to improve the adaptability of this bearing dismounting tool, the described body of rod 1 is length-adjustable Telescopic shaft type structure, can basis
It is actually needed, the length of the body of rod 1 is made accommodation.
Wherein, described cutting ferrule 2 inwall is provided with Nitinol wearing course, and cutting ferrule wearability is good, and permanent use is unlikely to deform, and is difficult to
Abrasion.
During use, the cutting ferrule 2 of dimension can be matched as required, utilize fixing screw that cutting ferrule is arranged on the body of rod, will
Cutting ferrule 2 alignment bearings end face is inserted in, and assists percussion force, after making the complete bearing set of cutting ferrule 2, screws holding screw 3,
The holding screw on the body of rod 1 is made to fasten axle, afterwards, it is possible to use iron staff or spanner etc. are inserted through in through hole, as reinforcing
Bar use, screws bearing, is allowed to loosening, slowly takes off bearing.
This utility model structure designs, and can match different size of frock head according to the bearing of different size, therefore, it is possible to
It is applicable to the dismounting of different size bearing, easy to use, time saving and energy saving, it is effectively increased the work efficiency of dismounting bearing.
The above, be only preferred embodiment of the present utility model, not make any to technical scope of the present utility model
Limit, thus every according to technical spirit of the present utility model, above example is made any trickle amendment, equivalent variations with repair
Decorations, all still fall within the range of the technical solution of the utility model.
