Problems solved by technology

At the same time, the inner hole of the existing planetary gear needs to be processed many times, and the precision control is difficult
[0003] In addition, the current pressure angle of the planetary gear is 20°. Although the transmission efficiency is good, the disadvantage is that the planetary gear is easy to form an undercut phenomenon during use, the bending resistance and impact resistance of the planetary gear are weak, and the service life is relatively short. short

Embodiment

[0019] like figure 1 Said, a planetary gear, comprising a gear body 1, said gear body 1 has a rim, said gear body is provided with a gear on the outer surface of the rim, and the pressure angle of the gear is 25-27°. The center of the rim of the gear body 1 is provided with a left end inner hole 4 and a right end inner hole 3 , and a retaining ring 5 is arranged between the left end inner hole 4 and the right end inner hole 3 .

[0020] In this embodiment, the diameter of the inner hole 4 at the left end is the same as that of the inner hole 3 at the right end. The retaining ring 5 is provided with retaining ring holes 2 evenly distributed, and at the same time, the diameter of the retaining ring holes 2 is smaller than the diameters of the inner hole 4 at the left end and the inner hole 3 at the right end.

[0021] In addition, considering the actual use effect, the retaining ring 5 is made of stainless steel and has a thickness of 1-2 cm. The gear body 1 is a ring-shaped g...

Abstract

The invention relates to a planet gear. The planet gear comprises a gear body and is characterized in that the gear body is provided with a gear rim, the outer circle surface of the gear rim of the gear body is provided with a gear, and the pressure angle of the gear is 25-27 degrees; the center of the gear rim of the gear body is provided with a left end inner hole and a right end inner hole; andbaffle rings are arranged between the left end inner hole and the right end inner hole. According to the planet gear, the baffle rings are arranged between left end inner hole and the right end innerhole of the planet gear, the left end inner hole and the right end inner hole are the same in diameter, machining and manufacturing are convenient, and precision control is accurate; and in addition,the pressure angle of the gear is 26.5 degrees, so that the pressure angle of the planet gear is more reasonable, the mechanical strength is good, and the service life is prolonged.

Description

technical field [0001] The invention relates to a planetary gear. Background technique [0002] Planetary gears are widely used in various machinery. The main features of planetary gear transmission are small size, large load capacity and stable operation. However, the transmission structure of high-power high-speed planetary gear is more complex, requiring high manufacturing precision. Some types of planetary gear transmission have high efficiency, but the transmission ratio is not large. Other types can have large gear ratios but are less efficient. When they are used as speed reducers, their efficiency decreases with the increase of transmission ratio, and self-locking may occur when they are used as speed increasers. At the same time, the inner hole of the existing planetary gear needs to be processed many times, and the precision control is difficult. [0003] In addition, the current pressure angle of the planetary gear is 20°. Although the transmission efficiency...
