Description

Novel planet wheel gasket

Technical Field

The utility model relates to a gasket field, more specifically relate to a novel planet wheel gasket.

Background

Planetary transmission is widely applied to traffic and transportation tools such as land, navigation, aviation and the like as a mature mechanical transmission mode. The common planet row is composed of a planet wheel, a planet carrier, a sun wheel and a gear ring, wherein the planet wheel does rotary motion around an axis in the working process, and can also move in the axial direction to cause abrasion between the planet carrier and the planet wheel, so that planet wheel gaskets are required to be added at two ends of a planet wheel shaft to serve as abrasion consumption parts.

At present, the planet wheel gasket at home and abroad is generally formed by machining a metal material, and the planet wheel gasket made of the metal material has the defects of high requirement on the parallelism of two surfaces, difficult machining, high rejection rate, complex machining process, high precision requirement, high manufacturing cost, heavy weight of the gasket, large heat generated by friction, strong heat conductivity and quick temperature rise; and the groove that current planet wheel gasket was opened is the straight flute, and the straight flute makes the rotatory in-process formation oil film of planet wheel inhomogeneous, and the lubricity is not good. Therefore, a planet wheel gasket which forms a more uniform oil film and has better lubricating property is urgently needed.

SUMMERY OF THE UTILITY MODEL

Based on above problem, the utility model provides a novel planet wheel gasket for it is inhomogeneous to make the rotatory in-process formation oil film of planet wheel, the not good problem of lubricity to solve the straight flute on the planet wheel gasket among the prior art. The utility model discloses a carve the shape with the oil groove design on the gasket body, the wedge oil groove is compared and is straightly shaped oil groove can form better oil film at the rotatory in-process of planetary gear, has promoted the lubricity.

The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:

the utility model provides a novel planet wheel gasket, includes the gasket body, it has a plurality of oil grooves, a plurality of radially to open along it on the gasket body the oil groove all is the wedge.

The working principle is as follows: when the planet wheel is rotatory, the advantage of the wedge oil groove on the gasket body contrast current straight oil groove is that make lubricating oil produce bigger normal acceleration under the centrifugal force effect, obtains faster oil speed of getting rid of, forms more even oil film, promotes holistic lubricating property.

Preferably, the width of the oil groove gradually increases from the inside to the outside.

Preferably, the oil grooves are uniformly distributed on the gasket body.

Preferably, the gasket body is made of polytetrafluoroethylene or polyetheretherketone.

Preferably, the gasket body is injection molded.

The utility model has the advantages as follows:

(1) the utility model discloses a carve the shape with the oil groove design on the gasket body, the wedge oil groove is compared and is straightly shaped oil groove can form better oil film at the rotatory in-process of planetary gear, has promoted the lubricity.

(2) The utility model discloses the width of well oil groove increases from inside to outside gradually, and lubricating oil gets rid of to narrow limit from the broadside of oil groove under the effect of centrifugal force like this, and lubricating oil can obtain bigger normal acceleration when getting rid of from narrow limit, obtains faster oily speed of getting rid of to can further form more even oil film, further promote holistic lubricating property.

(3) The utility model discloses well a plurality of oil grooves evenly distributed is on the gasket body, and the lubricating oil of throwing away from whole gasket body like this can be more even.

(4) The utility model discloses the material of well gasket body is polytetrafluoroethylene or polyether ether ketone. The adopted polytetrafluoroethylene composite material has large specific heat capacity and large thermal resistance coefficient, can effectively prevent the phenomenon of ablation and even gluing of the planet wheel and the gasket body caused by overheating due to friction, and is beneficial to realizing the integral weight reduction and light weight because the non-metallic material has the characteristics of low cost and light weight.

(5) The utility model discloses well gasket body injection moulding, the cost is lower like this, and processing technology is simpler.

Drawings

FIG. 1 is a schematic view of the front structure of the present invention;

FIG. 2 is a schematic cross-sectional view taken along line A-A of FIG. 1 according to the present invention;

reference numerals: 1 gasket body, 11 oil grooves.

Detailed Description

For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.

Example 1:

as shown in fig. 1-2, a novel planet wheel gasket comprises a gasket body 1, wherein a plurality of oil grooves 11 are radially formed in the gasket body 1 along the gasket body, and the oil grooves 11 are all in a wedge shape.

The working principle is as follows: when the planet wheel is rotatory, wedge oil groove 11 on the gasket body 1 compares the advantage of current straight oil groove 11 and is making lubricating oil produce bigger normal acceleration under the centrifugal force effect, obtains faster oil speed of getting rid of, forms more even oil film, promotes holistic lubricating property.

Example 2:

as shown in fig. 1 to 2, the present embodiment gives a more preferable mode of the gasket body 1 and the oil groove 11 on the basis of the above-described embodiments. The width of oil groove 11 increases from inside to outside gradually promptly, and lubricating oil gets rid of to the narrow limit from the broadside of oil groove 11 under the effect of centrifugal force like this, and lubricating oil can obtain bigger normal acceleration when throwing away from the narrow limit, obtains faster oil speed of throwing away to can further form more even oil film, further promote holistic lubricating property.

Preferably, the plurality of oil grooves 11 are uniformly distributed on the gasket body 1, so that the lubricating oil thrown off from the whole gasket body 1 is more uniform.

Preferably, the material of the gasket body 1 is polytetrafluoroethylene or polyetheretherketone. The specific heat capacity of the adopted polytetrafluoroethylene composite material is large, the thermal resistance coefficient is large, the phenomenon that the planet wheel and the gasket body 1 are ablated and even glued due to overheating caused by friction can be effectively prevented, and meanwhile, the non-metal material has the characteristics of low cost and light weight, so that the weight reduction and light weight of the whole body are favorably realized.

Preferably, the gasket body 1 is injection molded, so that the cost is lower and the processing technology is simpler.

The rest is the same as example 1, and therefore, will not be described herein.

The embodiment of the present invention is the above. The specific parameters in the above embodiments and examples are only for the purpose of clearly showing the verification process of the present invention, and are not used to limit the protection scope of the present invention, which is still subject to the claims, and all the equivalent structural changes made by using the contents of the specification and drawings of the present invention should be included in the protection scope of the present invention.
