Description

Durable planetary gear

Technical Field

The utility model relates to a gear especially relates to a durable planetary gear.

Background

In addition to the planet gears rotating about their own axes of rotation as fixed axis gears, their axes of rotation also rotate about the axes of the other gears with the blue carrier. Rotation around its own axis is called rotation, and rotation around the axis of another gear is called revolution, like a planet in the solar system, and hence the name. Planetary gear transmissions have many unique advantages over conventional gear transmissions. The most remarkable characteristic is that power splitting can be carried out when power is transmitted, and the input shaft and the output shaft are on the same horizontal line. Planetary gear transmissions have been widely used in reduction, speed-increasing and speed-changing devices in various mechanical transmission systems. However, the existing planetary gear is used as a standard part, and the structure is very simple, so that the running precision, the transmission efficiency and the service life of equipment are influenced. Therefore, a new technical solution should be provided to solve the above problems.

The further technical scheme is as follows:

a plurality of arc-shaped grooves are formed in the gear body.

The wear-resistant ring is made of wear-resistant rubber.

The further technical scheme is as follows:

four arc-shaped grooves are formed in the gear body.

Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have following advantage:

1. the utility model discloses a durable planetary gear, fixedly connected with wear ring on the outer lane of gear body, wear ring is formed by the preparation of wear-resisting rubber, and its wearability that can increase the gear body prolongs its life.

2. The utility model discloses a durable planetary gear is equipped with a plurality of constant head tank along its circumferencial direction upward interval on the inner wall in shaft hole, is equipped with the boss between adjacent constant head tank, and the setting of boss has improved the anti deformation strength and the atress intensity of constant head tank, and then has improved the atress intensity of gear, has prolonged the life of gear.

3. The utility model discloses a durable planetary gear is equipped with the rubber pad in the inside of constant head tank, and the spring is installed to the rubber pad rear end, and it can reduce the vibration that the gear produced in the motion process, noise reduction.
