Description
Technical field
The present invention relates to a kind of cylinder bodies, and in particular to a kind of cylinder body with needle bearing.
Background technology
In the prior art, clinopyramid tooth quantitative plunger pump, in high-speed cruising, cylinder center hole is run with centration axis friction
It is middle because fit clearance is small, locking damage is easily deformed due to temperature increases, while other accessories also damage, fit clearance mistake
Big efficiency is low.
Invention content
Goal of the invention：The purpose of the invention is to overcome deficiency of the prior art, provide it is a kind of simple in structure, easily
The interchangeable needle bearing cylinder body of band of replacement.
Technical solution：In order to solve the above-mentioned technical problem, the interchangeable needle bearing cylinder body of band of the present invention, it includes cone
Tooth cylinder body is equipped with bearing hole in the middle part of the cone tooth cylinder body, bearing I and bearing II, the bearing I is equipped in the bearing hole
The distance between cone tooth cylinder body end face of outer surface and the outer surface the same side and the length ratio of bearing hole be 1：（12-13）,
The length ratio of the distance between the outer surface of the bearing II and the cone tooth cylinder body end face of the outer surface the same side and bearing hole is
1：（16/25-18/25）.
The bearing I is pressed into close-fitting in bearing hole with bearing II and connects.
The bearing I and bearing II are needle bearing.
The distance between the outer surface of the bearing I and the cone tooth cylinder body end face of the outer surface the same side and the length of bearing hole
Degree is than being 1：12.5.
The distance between the outer surface of the bearing II and cone tooth cylinder body end face of the outer surface the same side and bearing hole
Length ratio is 1：17/25.
Advantageous effect：Compared with prior art, the present invention its remarkable advantage is：Structure setting of the present invention is reasonable, in bearing
Be equipped in hole the distance between bearing I and bearing II, the cone tooth cylinder body end face of the outer surface of bearing I and the outer surface the same side and
The length ratio of bearing hole is 1：（12-13）, between the outer surface of bearing II and the cone tooth cylinder body end face of the outer surface the same side
Distance and the length of bearing hole ratio are 1：（16/25-18/25）, it is pressed into place, by needle bearing, makes operation light and handy, replaces and hold
Easily, it as long as replacing needle bearing when safeguarding, is changed without entire cylinder body, less with worry because the locking of pump housing elevated temperature deformation is damaged
Bad other accessories, substantially reduce maintenance cost, more improve the service life of pump, meet actual operation requirements.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, the interchangeable needle bearing cylinder body of band of the present invention, it includes cone tooth cylinder body 1, in the cone tooth cylinder
Bearing hole 2 is equipped in the middle part of body 1, bearing I 3 and bearing II 4 are equipped in the bearing hole 2, the outer surface of the bearing I 3 is with being somebody's turn to do
The length ratio of the distance between 1 end face of cone tooth cylinder body of outer surface the same side and bearing hole 2 is 1：（12-13）, the bearing II 4
The distance between 1 end face of cone tooth cylinder body of outer surface and the outer surface the same side and the length ratio of bearing hole 2 be 1：（16/25-
18/25）；The bearing I 3 is pressed into close-fitting in bearing hole 2 with bearing II 4 and connects；The bearing I 3 and bearing II 4 are needle roller axis
It holds.Structure setting of the present invention is reasonable, bearing I and bearing II is equipped in bearing hole, the outer surface of bearing I and the outer surface are same
The length ratio of the distance between cone tooth cylinder body end face of side and bearing hole is 1：（12-13）, the outer surface of bearing II and the appearance
The length ratio of the distance between cone tooth cylinder body end face of face the same side and bearing hole is 1：（16/25-18/25）, it is pressed into place, leads to
Needle bearing is crossed, makes operation light and handy, it is easy to replace, as long as replacing needle bearing when safeguarding, is changed without entire cylinder body, more
Without worrying to damage other accessories because of the locking of pump housing elevated temperature deformation, substantially reduce maintenance cost, more improve pump uses the longevity
Life, meets actual operation requirements.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, more than institute
State only is the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the guarantor of the present invention
Range is protected, all undefined components in this embodiment can be implemented in the prior art.
