Belt tightening adjusting device of diesel engine

Abstract

The invention discloses a belt tightening adjusting device of a diesel engine. The belt tightening adjusting device is characterized in that a generator support is arranged on a diesel engine body, installation holes are respectively arranged at the upper end and the lower end of a generator installation disc, and a bolt penetrates through the lower end of the generator installation disc and fixed with the generator support on the installation holes through nuts. A section of arc groove is arranged on the front side of a tensioning support, and a long hole section is arranged on the lateral side of the tensioning support. A sliding block bolt sequentially penetrates through the installation holes arranged at the upper end of the generator installation disc and is fastened with the arc groove of the tensioning support through nuts. A threaded hole is arranged at the cylindrical end of the sliding block bolt, and a screw penetrates through a long hole on the lateral side of the tensioning support and is screwed into the threaded hole at the cylindrical end of the sliding block bolt. A transmission belt is horizontally embedded in a belt groove arranged at the outmost side of a generator, the sliding block bolt is led to displace along the arc groove of the tensioning support by adjusting the screw, and therefore tightening of the transmission belt is adjusted. The belt tightening adjusting device enables belt tightening adjusting to be very convenient, is not limited by small generator peripheral space, and can ensure consistency of tightening of the transmission belt on each trolley.

Description

technical field [0001] The invention belongs to engine parts, in particular to a diesel engine belt tension adjustment device. Background technique [0002] With the development of my country's transportation industry and the continuous improvement of people's living standards, people have put forward higher requirements for the reliability and ride comfort of cars. Vibration and noise are one of the main factors affecting comfort. The transmission wheel train at the front end of the diesel engine is driven by a poly-V-belt, which not only makes the structure of the diesel engine more compact, shortens the length of the whole machine, but also reduces the cantilever of the drive train train, which is beneficial to the reliability of the drive shafts of generators, air conditioners, and water pumps. Make the transmission more stable and effectively reduce vibration. The tension of the belt directly affects the running stability and transmission efficiency. The belt tension...

Problems solved by technology

The belt tension adjustment of the traditional diesel engine is controlled by the feel of the assembler, and it is inconvenient to adjust the belt. It is difficult to ensure the consistency of each car, and it is easy to cause uneven tension.

If the belt is too loose, the transmission efficiency will decrease, the rotation will be lost, and even the belt string groove will be worn faster; shaft failure
