Abstract
The utility model relates to a planet carrier assembly, in particular to a high-hardness annular gear for a reverse planet carrier assembly. The high-hardness annular gear for the reverse planet carrier assembly mainly solves the technical problems, existing in the prior art, that an annular gear for the reverse planet carrier assembly is complex in structure, complicated in manufacturing technique, high in production cost, low in hardness, short in service life, and poor in transmission efficiency. The high-hardness annular gear for the reverse planet carrier assembly comprises an annular gear body, wherein a gear body is arranged on the inner surface of the annular gear body, one end of the gear body is flush with one end surface of the annular gear body, a gap is reserved between the other end of the gear body and the other end surface of the annular gear body, an annular groove is formed in the inner surface, in the gap, of the annular gear body, a carburized layer is arranged on the outer surface of the gear body, and a positioning hole is formed in the root of the gear body.
Description
Technical field
The utility model relates to a kind of planet carrier assembly, especially relates to the special-purpose ring gear of a kind of high hardness reverse gear planet carrier assembly.
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 hardness is not high, and working life is shorter, and transmission efficiency is relatively poor.
The model utility content
The utility model provides the special-purpose ring gear of a kind of high hardness reverse gear planet carrier assembly, 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 higher, and hardness is not high, working life is shorter, 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 high hardness reverse gear planet carrier assembly of the present utility model, comprise the ring gear body, the internal surface of described ring gear body is provided with denticle, the end face of denticle one end and ring gear body, the end face of the denticle the other end and ring gear body has a determining deviation, and have annular groove on the ring gear body internal surface in this spacing, the outer surface of denticle is provided with carburized case, and the tooth root portion of denticle has positioning hole.Carburizing and quenching can be carried out in the surface of denticle, carburized layer depth 0.8-1.2mm, and surface hardness HRC56-62, core hardness HRC30-45, the hardness of whole like this ring gear is stronger.
As preferably, described denticle is provided with step near an end of annular groove.Utilize step more easily ring gear to be encased in the planet carrier assembly.
As preferably, the two ends of described ring gear body all are provided with chamfering.Utilize chamfering, can easily ring gear be encased in the axle of planet carrier assembly.
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 hardness 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, denticle 2, annular groove 3, positioning hole 4, step 5, chamfering 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 this routine high hardness reverse gear planet carrier assembly, as Fig. 1, comprise ring gear body 1, the internal surface of ring gear body is provided with denticle 2, the end face of denticle one end and ring gear body, the end face of the denticle the other end and ring gear body has a determining deviation, and has annular groove 3 on the ring gear body internal surface in this spacing, the outer surface of denticle is provided with carburized case, and the tooth root portion of denticle has positioning hole 4.Denticle is provided with step 5 near an end of annular groove 3.The two ends of ring gear body all are provided with chamfering 6.
During use, it is encased in the reverse gear 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.
