Abstract
The utility model relates to a planet carrier assembly, in particular to an easy-to-install planet wheel dedicated for the planet carrie assembly, and mainly aims at solving the technical problems that a planet wheel for a planet carrier assembly in the prior art is complex in structure, complex in manufacturing technology, high in production cost, not easy to assemble, low in transmission efficiency, and the like. The planet wheel comprises a cylindrical planet wheel body (1) and is characterized in that through holes (2) are formed inside the planet wheel body (1), tooth bodies (3) are evenly distributed on the outer surface of planet wheel body, tooth body chamfers (4) are arranged at two ends of each tooth body, and through hole chamfers (5) are arranged at two ends of each through hole.
Description
Technical field
The utility model relates to a kind of planet carrier assembly, especially relates to a kind of special-purpose planet wheel of planet carrier assembly of easy installation.
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 planetary 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 a kind of special-purpose planet wheel of planet carrier assembly of easy installation, it mainly is that to solve the planetary 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 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 planet wheel of the planet carrier assembly of easy installation of the present utility model, comprise columniform planet wheel body, the inside of described planet wheel body is provided with through hole, and the outer surface of planet wheel is evenly equipped with denticle, the two ends of denticle are provided with the denticle chamfering, and the two ends of through hole are provided with the through hole chamfering.Denticle and through hole all are provided with chamfering, make planet wheel comparatively to be easy to install in the planet carrier assembly.The nitrogencase hardening of planet wheel body, carburized layer depth 0.8-1.2mm, hardened face hardness HRC56-62, core hardness HRC30-45.
As preferably, the number of teeth of described planet wheel is 19, and modulus is 3.25.
Therefore, planet wheel 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: planet wheel body 1, through hole 2, denticle 3, denticle chamfering 4, through hole chamfering 5.
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 planet wheel of the planet carrier assembly of the easy installation of this example as Fig. 1, comprises columniform planet wheel body 1, the inside of planet wheel body is provided with through hole 2, the outer surface of planet wheel is evenly equipped with denticle 3, and the two ends of denticle are provided with denticle chamfering 4, and the two ends of through hole are provided with through hole chamfering 5.The number of teeth of planet wheel is 19, and modulus is 3.25.
During use, it is encased in the 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.
