Description

A RH harmonic reducer device

technical field

The invention relates to a reducer, in particular to an RH harmonic reducer device.

Background technique

The reducer is generally used for low-speed and high-torque transmission equipment. The motor, internal combustion engine or other high-speed running power is used to achieve the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer and the large gear on the output shaft. Ordinary The reducer will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

The principle of its motion is that the small cylinder in the inner wheel cavity makes circular motion, which can realize the differential meshing of the inner and outer gears, and make them move, so as to carry out tooth-to-teeth mutual meshing with the outer wheel. Because every time the small cylinder turns a full circle, the corresponding point reaches an extreme value, that is, one tooth moves, so as to achieve the effect of deceleration.

Detailed ways

A RH harmonic reducer device as shown in Figure 1 and Figure 2 includes a central shaft assembly 1, which is different in that: the peripheral working surface of the central shaft assembly 1 used in the present invention passes through the main bearing assembly sleeve An internal gear assembly 2 is provided. At the same time, considering the smooth progress of deceleration transmission, the outer gear 3 is sheathed on the outer working surface of the inner gear assembly 2 . Moreover, the front end of the central shaft assembly 1 is connected with an integral cross bearing 4, so that the structure of the reducer is more compact and the rigidity is enhanced. Correspondingly, an auxiliary bearing assembly is connected to the tail end of the central shaft assembly 1 .

As far as a preferred embodiment of the present invention is concerned, the main bearing assembly adopted is the deep groove ball bearing 5 in consideration of making the rotation of the main bearing assembly smoother and functioning as a double support structure. In this way, the force couple of the overall structure of the reducer is more balanced, the strength is higher, the output is more stable, and the reducer works more smoothly.

Further, in order to realize the smooth and precise deceleration process, each tooth moves to achieve the deceleration effect, and the internal gear assembly 2 used is composed of at least two identical internal gears arranged side by side.

At the same time, considering that it needs to bear radial load and axial load at the same time, it can also bear pure axial load, and can work at a higher speed. The auxiliary bearing assembly used in the present invention is a four-point contact ball bearing 6 .

Looking further, considering the connection of the client, the rear end of the central shaft assembly 1 is provided with a keyway 7 . At the same time, in order to facilitate customers' cables to pass through in the middle, a hollow shaft channel 8 is arranged in the central shaft assembly 1 . Moreover, the inner wall of the hollow shaft channel 8 is provided with connecting threads, which facilitates the installation of other components. In this way, the space and raw materials used under the same specification can be satisfied and saved.

It can be seen from the above textual expressions that after adopting the present invention, the existence of the hollow shaft channel and the machining precision are guaranteed, so that the structure of the whole part is more compact and the precision is higher. At the same time, considering the user, it is not only convenient and practical, but also optimizes the overall structure on this basis, making it more compact and precise, with more stable output and more stable work of the reducer.
