Problems solved by technology

Occasionally, there are planetary transmission patents that mention hypocycloids. For example, the hypocycloid arc used in the tooth profile of the hypocycloid wheel in the patent No. 93210989.6 "Hycloidal Reducer" is essentially the outer equidistant curve of the short epicycloid. (the number of teeth of the needle wheel is one tooth more than that of the hypocycloid wheel), which conforms to the principle of epicycloid meshing and has not yet involved the hypocycloid

Embodiment Construction

[0062] The hypocycloid planetary transmission is a new type of cycloidal planetary transmission designed on the principle of hypocycloid formation and meshing. The structure and components that make up this transmission device are shown in the appendix Figure 5 .

[0063] The planetary carrier is composed of an input shaft (4) and double eccentric sleeves (5), and the two eccentric directions on the eccentric sleeves (5) are mutually 180°. Usually one end of the input shaft (4) is supported on the back cover (2), and the other end is supported on the front force transmission disc (15).

[0064] The planetary gear is a pin wheel formed by alternately installing short pins (9) (not used when the number of teeth is small) and long pins (13) on the pin rack (8). Usually, pin gear sleeves (10) are installed on the pin gear, and (1-2) rotating arm bearings (6) are installed in a pin gear frame (8). A group of through holes that can pass through the connecting rod (3) are arrange...

Abstract

The invention is a planetary gearing, designed by hypocycloid forming and engaging principles, engaging hypocycloidal wheel with pin gears, using a hypocycloidal wheel with external equidistant curve of curtate hypocycloid (or hypocycloid) as a center wheel, and using pin gears with pin teeth as planetary gear mounted on a tumbler shaft with eccentric distance A, where a pinhole output mechanism directly drives front transfer dish, rear transfer dish and balanced transfer ring of a combined output shaft by extensions of long pin teeth on the pin gears, to make angular speed output of two pin gears with 180 deg. phase shifted in equal speed ratio. And it has many advantages of the existing cycloidal-pin gear planetary gearing and can largely improve load-bearing capacity and transfer power, reduce bulk of driving device, improve rigidity and shock resistance of output shaft, realize dynamic balance of input shaft, and apply to high speed, heavy load and large power driving.

Description

[0001] (1) Technical field: the present invention relates to the field of mechanical planetary transmission (two) background technology: [0002] The cycloid pin wheel planetary transmission is a planetary transmission in which the epicycloid wheel and the pin gear are meshed according to the principle of epicycloid meshing. See attached figure 1 , the center wheel b is a pin wheel with cylindrical needle teeth, the planetary wheel a is an epicycloid wheel with a tooth profile of an inner equidistant curve of a short epicycloid, the arm shaft H with an eccentricity A and the hole pin type The composition of the output mechanism. Its output mechanism is that the pillar pins (2) are arranged on the disc of the output shaft (4), the pillar pins (2) have a pillar pin sleeve (1), and the pillar pins with sleeves are inserted into the pillar pins of the two cycloidal wheels a together. in the hole. During the transmission process, the pin sleeve (1) is in contact with the pin hol...
