Abstract

The invention relates to a chain tensioning adjusting mechanism which comprises a shell, a direct drive motor, a drive controller, a transmission device, a transmission lead screw, a first connector device, a chain and a second connector device. The direct drive motor is arranged in the shell, and the drive controller is arranged at the upper end of the shell and is connected with the direct drive motor through a line; a supporting plate is arranged on the outer side of the shell, the transmission device is arranged on the side, close to the shell, of the supporting plate, and the direct drive motor is connected with the transmission device; one end of the transmission lead screw penetrates the supporting plate to be connected with the output end of the transmission device, and the other end of the transmission lead screw is connected with one end of the first connector device; the other end of the first connector device is connected with the second connector device through a chain; and a tension sensor is arranged at the connecting position of the first connector device and the chain and is connected with the drive controller through a line. By means of the chain tensioning adjusting mechanism, automatic chain tensioning is achieved, the chain driving accuracy is improved, chain falling is prevented, the chain tensioning adjusting mechanism can adapt to the wicked work environment, and the reliability coefficient is high.

Description

technical field [0001] The invention relates to the technical field of tension adjustment, in particular to a chain tension adjustment mechanism. Background technique [0002] The chain will wear and tear when it continues to work. The intensification of this wear will cause the chain to relax on the basis of the initial tension, and the tension of the chain will decrease accordingly, which will affect the working condition of the chain and even the entire system. For the occasions where the chain drive precision is very high, the change of the chain spacing caused by some tiny chain wear that cannot be distinguished by the naked eye will affect the drive precision of the entire system. Even if the chain is found to be slack, the original tensioning device can only be stopped manually. Adjust and re-tension. The traditional chain tensioning device cannot realize automatic and accurate tensioning under the start-up condition. It can only perform preliminary tensioning before ...
