Problems solved by technology

Looking at the current situation of domestic CNC cardless rotary cutting machines, it is difficult to achieve the above processing range only by frequency converters without the help of mechanical transmission systems. Generally, frequency converters have poor performance in both high and low frequencies. To meet the above processing range, the frequency conversion must be greatly increased. The power configuration of the machine and the feed motor, there is a phenomenon of large horses and small carts, the excess power of the knife motor when rotary cutting thick skins and small diameters is still insufficient torque when rotary cutting large diameter thin skins, resulting in a great waste of resources

Embodiment 1

[0037] as attached figure 1 Shown, the multifunctional free clutch of the present invention, its structure comprises planetary gear train frame, planetary gear train, sun gear train;

[0038] The planetary gear train frame includes a frame gear 1 and a frame pulley 2 that are fixedly connected coaxially. Two sets of planetary gear trains are arranged in the cavity formed by the frame gear 1 and the frame pulley 2. The two sets of planetary gear trains are based on the frame gear 1 wheel The central axis is a symmetrical point, which is symmetrically arranged on the diameter of the frame gear 1 wheel disc.

[0039] The planetary gear train includes an input planetary gear 3, an output planetary gear 4 and a planetary gear shaft 5. The input planetary gear 3 and the output planetary gear 4 are splined to the planetary gear shaft 5, and one end of the planetary gear shaft 5 is connected to the frame gear 1 through a bearing. On the planet shaft shaft hole 4, the other end is con...

Embodiment 2

[0043] as attached Figure 13 As shown, the multi-functional free clutch is used as a clutch, and its function is equivalent to the function of two electromagnetic clutches, and its advantage is that there is no free change in speed during the neutral time.

[0044] Take the currently widely used rotary cutting machine as an example, as attached Figure 13 As shown, the working principle and application method are as follows: the main force 19 is passed into the hanging wheel frame shaft input sprocket 17 through the chain, the hanging wheel frame shaft is input into the sprocket 17, the constant connection thickness conversion hanging wheel frame 14, the thickness quick change control hanging wheel The wheel frame 15 is coaxially threaded on the wheel frame shaft 16, and there is a flat key connection between them, and the thickness of the wheel frame 14 is connected to the input gear 9 of the multifunctional free clutch 13, which can be kept connected without disconnection. ...

Embodiment 3

[0049] The multifunctional free clutch also has the function of a speed reducer and can be directly used as a speed reducer.

[0050] The multifunctional free clutch is directly used as a reducer, and it needs to be attached figure 1 On the basis of the shown structure, the following changes are made: (1) the tooth profile of the frame gear 1 is removed, and the rest of the structure remains unchanged, and the name is changed to the planetary wheel frame 1; (2) the input gear 9 and the output sprocket 10 are removed; (3) Redesign the output shaft bearing seat 12 on one side, add the inner hole for fixing the input sun gear 6, and draw the keyway; the application method is as follows:

[0051] Except for the above three changes, the structure of the other free clutches remains unchanged. Only the outer circle of the sleeve of the input sun gear 6 protruding from the planetary gear frame 1 is fixed on the inner hole of the output shaft bearing seat 12 through a flat key to form ...

Abstract

The invention provides a multifunctional free clutch, solves the technical problems of alternated input and cross superposition of multiple inputs, and belongs to the technical field of mechanical transmission. The clutch is structurally characterized in that a set or more than a set of planetary gear train is arranged in a planetary gear train framework; the planetary gear train consists of an input planetary gear, an output planetary gear and a planetary gear shaft in spline connection; and a sun gear train consists of an output shaft and an output sun gear in spline connection, the output sun gear is meshed with the output planetary gear, the output shaft is connected with a shaft sleeve to drive an integral input sun gear, and the input sun gear is meshed with the input planetary gear. The clutch has the functions of two electromagnetic clutches during use, has the advantage of free change of non-neutral time and speed, can also be used as a decelerator, has the function of a differential mechanism, can be used for synthesis of speed, and has wide application.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a multifunctional free clutch. Background technique [0002] Generally, the clutches in the prior art can be divided into two types according to the working principle of its transmission torque: fitting type and friction type; ); can be divided into mechanical type, pneumatic type, hydraulic type, electromagnetic type (such as electromagnetic clutch) according to its operation mode. In the existing mechanical structure, it is often necessary to have multiple inputs and one output. In order to improve the degree of automation, electromagnetic clutches or overrunning clutches are often used. No matter which clutch has a separation and engagement process, frequent separation and engagement will affect the service life of the clutch. . There is a gap time when using electromagnetic clutches, and as many electromagnetic clutches are needed as there are inputs. Using ...
