Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In fig. 1 to 3, a duplex-drive reduction gear comprises a driving member 10, an intermediate commutator 5 and two first brake clutch assemblies.

A driving member 10 is provided at one end of the intermediate commutator 5 in the longitudinal direction. Two ends of the middle commutator 5 in the width direction are respectively provided with a first brake clutch component. A first roller 1 is arranged at one end of the first brake clutch assembly, which is far away from the middle commutator 5. The driver 10 controls the first brake clutch assembly via the intermediate commutator 5.

The intermediate commutator 5 is provided with a first bevel gear 51, a second bevel gear 52 and a third bevel gear 53. The first bevel gear 51 meshes with the second bevel gear 52 and the third bevel gear 53, respectively. One end of the second bevel gear 52 and one end of the third bevel gear 53 are respectively abutted with the first brake clutch assembly. The intermediate commutator 5 is also provided with a connecting shaft 15. The driving member 10 is provided with a rotation shaft 11. One end of the connecting shaft 15 is keyed with the rotating shaft 11, and the other end of the connecting shaft 15 is provided with a first bevel gear 51.

The first brake clutch assembly includes a first dual brake 3, a first clutch 4 and a first speed reducer 2. One end of the first speed reducer 2 is provided with a first roller 1, and the first roller 1 is perpendicular to the rotating shaft 35. The first double brake 3 is provided with a rotating shaft 35. The two ends of the rotating shaft 35 are respectively and coaxially connected with the first clutch 4 and the first speed reducer 2. A contact shaft 55 is provided at one end of the intermediate commutator 5 in the width direction. The axis of the abutment shaft 55 coincides with the axis of the rotation shaft 35. Two framework oil seals 31 are arranged at one end of the first double brake 3 close to the first speed reducer 2. A bearing 32 is provided at one end of the first double brake 3 near the first clutch 4. The first double brake 3 is a double brake module, and the braking safety is improved.

When the load is 600 kilograms, the first roller 1 of the first brake clutch assembly is sometimes required to be driven, and the two rollers are sometimes required to be driven simultaneously. When the driving is carried out simultaneously, the left and the right sides need to be synchronous, so that only one power is available. It is also to be realized that braking can be done either individually or simultaneously. A first double brake 3 and a first clutch 4 of a double module are added at the input end of a first speed reducer 2, when the double brakes need to be driven simultaneously, the clutches on two sides are closed, and a left roller and a right roller can rotate simultaneously.

When the first roller 1 of one first brake clutch assembly works and the first roller 1 of the other first brake clutch assembly does not work, the first clutch 4 of one first brake clutch assembly is closed, and the first clutch 4 of the other first brake clutch assembly is opened.

The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
