Detailed Description

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

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example 1:

as shown in fig. 1, the roller transmission connecting belt comprises a transmission layer 1, a framework layer 2 and an outer layer 3. The transmission layer 1 is directly contacted with the roll shaft and sleeved on the roll shaft to drive the roll shaft to move. The framework layer 2 is used for connecting the outer layer 3 with the transmission layer 1 and improving the tear resistance and tensile strength of the integral connecting belt. The diameter of outer 3 is the biggest, and when two roller of the different distances of adaptation, outer 3 deformation volume is the biggest, consequently outer 3 has better elasticity, can produce the roller connection of the different distances of great deformation volume adaptation.

The middle part of the outer edge of the outer layer 3 is provided with a groove 7. The setting of recess 7 is used for material saving on the one hand, and on the other hand reduces the resistance of outer 3 when tensile, improves elasticity and the stretchability of outer 3 on the physical layer face to, set up recess 7 at the middle part and can carry out force balance to recess 7 both sides, make the connecting band can not take place the skew in the motion process.

The transmission layer 1 can be made of rubber material such as natural rubber. The framework layer 2 is made of ethylene propylene diene monomer rubber or fluorine-containing rubber containing carbon black, and has strong tear resistance. The outer layer 3 is made of TPU rubber or CPU rubber and has good elasticity and tensile property.

In addition, the transmission layer 1, the framework layer 2 and the outer layer 3 are integrally arranged in a U shape. The connecting band presents the U-shaped setting and helps the atress concentrate, conveniently provides bigger power for the roller motion.

Example 2:

the difference from the embodiment 1 is that, as shown in fig. 2, 3 and 4, the friction strips 4 are arranged in the circumferential array on the inner side of the transmission layer 1, the friction strips 4 can be made of silicon rubber or butadiene-acrylonitrile rubber, and the friction coefficient of the friction strips 4 is large. The friction strip 4 is provided with an arc-shaped surface 5 and a plane 6, the moving direction of the roll shaft needs to be considered when the friction strip is installed on the roll shaft, and the moving direction of the roll shaft is opposite to the direction of the plane 6. The reason is that the frictional force of plane 6 and roller contact is great for providing great frictional force and driving the roller motion, the setting of arcwall face 5 is used for being pressed by the roller and takes place deformation after the roller passes through plane 6, and setting up of whole friction strip 4 is similar with the ratchet setting, provides a guiding force for the roller motion, promotes the unidirectional movement of roller. As shown in fig. 5 and 6, the rubbing strip 4 is in a partial contact motion state with the roller shaft, and when the roller shaft moves, the rubbing strip 4 and the roller shaft move in opposite directions to provide a propelling force, so that the roller shaft is driven to move. After passing through the plane 6, the roll shaft moves in one direction under the guiding action of the arc-shaped surface 5. Fig. 8 shows a state where the connection belt is connected to the roller shaft.

The framework layer 2 is a supporting framework of the outer layer 3 and the transmission layer 1, plays a role in preventing the outer layer 3 from being torn and connecting the transmission layer 1, and achieves the purpose of improving the overall physical strength of the connecting belt.

The deformation volume of outer 3 is great compared with framework layer 2 and transmission layer 1 for the torn possibility greatly increased of outer 3 prevents through framework layer 2 that outer 3 is torn, and does not influence the tensile properties of outer 3, makes the connecting band can adapt to the roller installation of different distances.

The transmission layer 1, the framework layer 2 and the outer layer 3 are structurally shown in fig. 7, connecting blocks 8 in opposite directions are arranged on two sides of the framework layer 2, and connecting grooves 9 matched with the connecting blocks 8 are formed in the corresponding transmission layer 1 and the corresponding outer layer 3. The connecting belt is constructed in a nested mode, so that the connection between the framework layer 2 and the transmission layer 1 and between the framework layer and the outer layer 3 is tight, the possibility of separation of the framework layer 2 from the outer layer 3 and the transmission layer 1 is reduced, the connection between the connecting block 8 and the outer layer 3 is tight, and the outer layer 3 is further prevented from being torn. The connecting blocks 8 on the two sides of the framework layer 2 are arranged in the opposite direction, so that the tearing strength of the whole connecting belt in all directions tends to be consistent, and the adaptability of the connecting belt is improved.
