Abstract
The utility model discloses a kind of hyperboloid spiral grooved bearing.The utility model includes top chock, bearing spindle and step, the outer surface that described bearing spindle is engaged with top chock, step is the rotation hyperboloid of one sheet, and helicla flute is offered in the rotation hyperboloid of one sheet, hyperboloid spiral grooved bearing is formed.The utility model has more preferable stability and heat-sinking capability compared with normal spiral groove bearing, and the use requirement to lubricant is reduced, and can not only bear radial load can also bear two ends axial load, also improve the bearing capacity of bearing.
Description
Technical field
The utility model is related to a kind of spiral grooved bearing, more particularly, to a kind of hyperboloid spiral grooved bearing.
Background technology
Spiral grooved bearing is exactly that, using a part of helicla flute of tumbler, the high pressure oil film produced in operation process comes
Support rotary body.It is widely used in high speed situation.But traditional spiral grooved bearing presence can only bear unidirectional axial load, hold
The shortcomings of loading capability is relatively low.In addition traditional spiral grooved bearing surface convection current is slow, thermal diffusivity is poor, easily makes bearing and bearing block
Between lubricant viscosity decline, cause lubricant failure, the waste heat of work, which can not distributed, to be also easy to aggravate bearing wear.
Utility model content
Can only bear unidirectional axial load to solve conventional helical groove bearing presence in background technology, bearing capacity compared with
It is low, the shortcomings of bearing surface convection current is slow, thermal diffusivity is poor, bi-directional axial load can be born the utility model proposes one kind,
Stability and the good hyperboloid spiral grooved bearing of thermal diffusivity.
The technical solution adopted in the utility model is：
The utility model includes top chock, bearing spindle and step, described bearing spindle and top chock, under
The outer surface that bearing block is engaged is the rotation hyperboloid of one sheet, and offers helicla flute in the rotation hyperboloid of one sheet, is formed
Hyperboloid spiral grooved bearing.
The shape of cross section of described helicla flute is rectangle or triangle.
The helicla flute slot number span having in the described rotation hyperboloid of one sheet be 1~20, preferred scope be 7~
15。
The helical angle span of described helicla flute is 1 °~70 °, and preferred scope is 8 °~25 °.
The utility model has an advantageous effect in that：
The outer surface that bearing spindle and upper and lower axle bearing coordinate is designed to the rotation of symmetry, stability and thermal diffusivity well
Turn hyperboloid of one sheet shape so that the hyperboloid spiral grooved bearing in the utility model can not only bear radial load can be with
Two ends axial load is born, the bearing capacity of bearing is improved.
In addition, the utility model also increases contact surface area, antiwhip and thermal diffusivity are improved, to lubricant
Use requirement reduction, improve bearing working life.
Brief description of the drawings
Fig. 1 is hyperboloid spiral grooved bearing schematic cross-sectional view when helicla flute cross sectional shape is rectangle.
Fig. 2 is hyperboloid spiral grooved bearing schematic cross-sectional view when helicla flute cross sectional shape is triangle.
Wherein：1st, top chock, 2, bearing spindle I, 3, step, 4, bearing spindle II.
Embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
Embodiment of the present utility model is as follows：
Embodiment one
As shown in figure 1, the hyperboloid spiral grooved bearing of the present embodiment includes bearing spindle I 2, top chock 1, step
3.The outer surface that bearing spindle I 2 coordinates with top chock 1, step 3 is designed as rotating the hyperboloid of one sheet, in the single leaf of rotation
Helicla flute is offered on hyperboloid.Helicla flute cross sectional shape is rectangle, and the number of helicla flute is 7, and the helical angle of helicla flute is
8°。
Compared with conventional trochoid spiral groove bearing, the utility model, which can not only bear radial load, can also bear two
Axial load is held, the bearing capacity of bearing is improved.In addition, the utility model also increases the contact surface area of bearing spindle,
Antiwhip and thermal diffusivity are improved, the use requirement to lubricant is reduced, and improves the working life of bearing.
Embodiment two
As shown in Fig. 2 the hyperboloid spiral grooved bearing of the present embodiment includes bearing spindle II 4, top chock 1, lower bearing
Seat 3.The outer surface that bearing spindle II 4 coordinates with top chock 1, step 3 is designed as rotating the hyperboloid of one sheet, single in rotation
Helicla flute is offered on hyperboloid of two sheets.Helicla flute cross sectional shape is triangle, and the number of helicla flute is 7, the spiral of helicla flute
Angle is 8 °.
Compared with conventional trochoid spiral groove bearing, the utility model, which can not only bear radial load, can also bear two
Axial load is held, the bearing capacity of bearing is improved.In addition, the utility model also increases the contact surface area of bearing spindle,
Antiwhip and thermal diffusivity are improved, the use requirement to lubricant is reduced, and improves the working life of bearing.
Above-mentioned embodiment is used for illustrating the utility model, rather than the utility model is limited,
In spirit and scope of the claims of the present utility model, any modifications and changes made to the utility model all fall
Enter protection domain of the present utility model.
