Abstract
The utility model relates to a planet carrier assembly, in particular to an inner gear ring for a high strength first-gear planet carrier assembly. The inner gear ring mainly solves the technical problems that an inner gear ring of a planet carrier assembly in the prior art is complex in structure and manufacturing process, high in production cost, uneasy to assemble, poor in transmission efficiency and the like. The inner gear ring for the high strength first-gear planet carrier assembly comprises an inner gear ring body (1) and is characterized in that the section of the inner gear ring body (1) is in a T shape, and an inner gear body (2) is arranged on the inner surface of the small end of the inner gear ring body, and an outer gear body (3) is arranged on the outer surface of the large end of the inner gear ring body.
Description
Technical field
The utility model relates to a kind of planet carrier assembly, especially relates to the special-purpose ring gear of one grade of planet carrier assembly of a kind of high strength.
Background technique
It is very extensive that planetary type gear transmission unit uses in auto parts machinery, as in clutch; One comprises gear ring, planet carrier and sun wheel shaft planetary type gear transmission unit, different velocity ratios is arranged between gear ring, planet carrier and the sun wheel shaft, go out the modes that is connected different between end and gear ring, planet carrier and the sun wheel shaft by input end, axle, can obtain different speed changing effect.Chinese patent discloses a kind of planet carrier assembly (notice of authorization number: CN 202327039 U), it comprises the planet support body, the planet support body is a cylindrical body, one end of planet support body is provided with output shaft, the other end of planet support body is provided with installation base, be provided with a ditch cavity with an end opening in the planet support body vertically, opening is positioned on the end that described planet support body has installation base, be evenly equipped with at least 3 installation cavitys that planet wheel can be installed on the sidewall of ditch cavity, this installation cavity radially runs through the planet support body and is connected with the ditch cavity, the two side of installation cavity is provided with the mounting hole that is located along the same line and runs through the planet support body vertically, be provided with planet wheel shaft in the installation cavity, the two ends of this planet wheel shaft are fixed in the mounting hole, and this planet wheel shaft is set with planet wheel outward, and planet wheel can rotate relative to planet wheel shaft; Planet support body and output shaft are made one, are provided with bearing between planet wheel and the planet wheel shaft.But the ring gear structure that this planet carrier assembly is used is comparatively complicated, and manufacturing process is comparatively numerous and diverse, and cost of production is higher, and assembling is comparatively difficult, and transmission efficiency is relatively poor.
The model utility content
The utility model provides the special-purpose ring gear of one grade of planet carrier assembly of a kind of high strength, it mainly is that to solve the ring gear structure that the existing in prior technology planet carrier assembly uses comparatively complicated, manufacturing process is comparatively numerous and diverse, cost of production is lower, and assemble comparatively difficult, the technical problem of the relatively poor grade of transmission efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The special-purpose ring gear of one grade of planet carrier assembly of high strength of the present utility model comprises the ring gear body, and the section of described ring gear body is the T font, and the small end internal surface of ring gear body is provided with inner tooth body, and the big end outer surface of ring gear body is provided with outer denticle.Carburizing and quenching, carburized layer depth 0.8-1.2mm, surface hardness HRC56-60, core hardness HRC30-45 can be carried out in the surface of inner tooth body, outer denticle.The ring gear body of T font is arc transition all in the bending place, and intensity is stronger like this.
As preferably, the tooth root place of described outer denticle has positioning hole.Positioning hole is drilled in the tooth root place, and it is interspersed along circumference.
As preferably, the two ends of described inner tooth body are provided with chamfering.Utilize chamfering, can easily ring gear be encased in the axle of planet carrier assembly.
As preferably, described outer denticle is provided with positioning block.
Therefore, ring gear manufacturing process of the present utility model is comparatively simple, and cost of production is lower, and assembling is comparatively easy, and intensity is higher, and transmission efficiency is better, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering among the figure: ring gear body 1, inner tooth body 2, outer denticle 3, positioning hole 4, chamfering 5, positioning block 6.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the special-purpose ring gear of one grade of planet carrier assembly of this routine high strength, as Fig. 1, comprise ring gear body 1, the section of ring gear body is the T font, the small end internal surface of ring gear body is provided with inner tooth body 2, and the big end outer surface of ring gear body is provided with outer denticle 3.The tooth root place of outer denticle has positioning hole 4.The two ends of inner tooth body are provided with chamfering 5.Outer denticle is provided with positioning block 6.
During use, it is encased in one grade of planet carrier assembly gets final product.
The above only is specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
