Abstract
The utility model relates to a planet carrier assembly, in particular to a special alloy steel planet shaft for a reverse gear planet carrier assembly. The special alloy steel planet shaft mainly solves the technical problems that the planet shaft for the existing planet carrier assembly is relatively complicated in structure, relatively miscellaneous in manufacturing technology, higher in production cost, relatively difficult to assemble and poorer in transmission efficiency in the prior art. The special alloy steel planet shaft comprises a planet shaft main body (1) and is characterized in that the planet shaft main body (1) is made of 20CrMnTi alloy steel, wherein a carburized layer is arranged on the surface of the planet shaft main body; an oil hole (2) is formed in a shaft body of the planet shaft main body and communicated with an inclined oil injection channel (3); and an inclination angle alpha of the oil injection channel is 30-40 degrees.
Description
Technical field
The utility model relates to a kind of planet carrier assembly, especially relates to a kind of reverse gear planet carrier assembly special metals steel planet axis.
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 planet axis 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 a kind of reverse gear planet carrier assembly special metals steel planet axis, it mainly is that to solve the planet axis 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 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:
Reverse gear planet carrier assembly special metals steel planet axis of the present utility model, comprise the planet axis body, described planet axis body is made by the 20CrMnTi alloyed steel, the surface of planet axis body is provided with carburized case, and have oilhole on the axle body of planet axis body, oilhole is communicated with the oiling passage of oblique setting, and the inclined angle alpha of oiling passage is 30-40o.The nitrogencase hardening of planet axis body, carburized layer depth 0.8-1.2mm, hardened face hardness HRC58-64, core hardness HRC33-45.The oblique planet axis body that runs through of oiling passage.
As preferably, have rectangle groove on the axle body of described planet axis body.Rectangle groove can play the effect of location.
As preferably, the two ends of described planet axis body are provided with chamfering.Utilize chamfering, can planet axis be encased in the ring gear of planet carrier assembly easily.
Therefore, planet axis 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.
