Problems solved by technology

[0002] In the planetary gear transmission system, when the load distribution is uneven, it is easy to generate vibration, increase noise, and even break the gear teeth, thereby shortening its service life. Therefore, the improvement of the uneven load distribution between planetary gears must be considered.

Embodiment Construction

[0011] figure 1 It is a structural schematic diagram of the present invention, as shown in the figure: the planetary mechanism load sharing system of this embodiment includes a synchronous load sharing system that is connected between each planetary gear 1 in the planetary mechanism and is used to synchronously adjust the position of the planetary gears to achieve load sharing Mechanism: Due to the influence of machining accuracy, there is a certain fit gap between the planetary gear 1, the sun gear 2 and the ring gear 6. After adjusting the rotation angle of the planetary gear 1 to eliminate the above gap, connect the synchronous load equalizing mechanism to each planet Between the wheels 1, each planetary gear 1 is mutually constrained to realize the synchronous rotation of each planetary gear 1, and avoid the operation delay of the planetary gear 1.

[0012] In this embodiment, the synchronous load equalizing mechanism includes a balancer 3 and a connecting rod 4; the balan...

Abstract

The invention discloses a uniform load system of a planet mechanism. The uniform load system comprises a synchronous uniform load mechanism which is in transmission connection to the part among planet wheels in the planet mechanism and is used for synchronously adjusting the positions of the planet wheels to achieve the uniform load. According to the uniform load system of the planet mechanism, after the planet wheels are adjusted to be sufficiently engaged with an inner gear ring and a sun wheel, the synchronous uniform load mechanism is arranged, and the planet wheels synchronously rotate. Accordingly, sufficient meshing among the planet wheels, the inner gear ring and the sun wheel is kept, a meshing gap between the planet wheels in the planet mechanism is eliminated, and the running delay of the planet wheels is avoided.

Description

technical field [0001] The invention relates to a load equalizing system, in particular to a planetary mechanism load equalizing system. Background technique [0002] In the planetary gear transmission system, when the load distribution is uneven, it is easy to generate vibration, increase noise, and even break the gear teeth, thereby shortening its service life. Therefore, the improvement of the uneven load distribution between planetary gears must be considered. Especially when the number of planetary gears is more than three, the planetary gears are more likely to be eccentrically loaded. The main reasons for the unbalanced load distribution are as follows: First, the inevitable errors in manufacturing and assembly. The error is roughly divided into two parts: the manufacturing error of the gear itself and the comprehensive error of the manufacturing and assembly of the planet carrier, box, bearing, etc. Since the sun gear is required to maintain a balanced mesh with se...
