Analyze the significance of the influence of bolt tightening torque on generator rental connection box

Generator rentalBusiness is very common in Shenzhen. Due to peak power consumption restrictions and some construction sites must rent generators to generate electricity for construction. The connection box is one of the key components of the diesel generator set. The connection box is connected by bolts, and the tightening torque of the bolts is affected by many factors. Affected by several factors, and insufficient tightening torque during operation will lead to loosening of connections or failure of bolts. Taking into account changes in the physical parameters (weight, center of gravity, mounting base position, etc.) of the diesel engine and main generator and the impact of impact vibration during operation , and the influence of conditions such as torque, bending moment, shear stress, tensile stress, impact load, and excitation load of each gear speed of the diesel engine during the working process of the connecting box bolts of the diesel generator set. Based on the analysis of the stress on the bolts, the connecting box bolts were studied Factors affecting the tightening torque and establish a calculation process for the tightening torque of the connection box bolts for diesel engines. The research results can provide a reference for the calculation of the tightening torque of the connection box bolts of different types of diesel generator sets.

The main function of the generator rental connection box is to connect the diesel engine and the main generator, and to fix the diesel engine and the main generator as a whole to form a diesel generator set. Because the connection box not only has to withstand the vibration of the diesel generator set when working, but also withstands the diesel The reaction force on the casing when the generator set shaft system rotates. Therefore, appropriate bolt tightening torque should be selected when installing the connection box to ensure that the diesel engine and main generator remain stable and tight when the locomotive is running. Tighten the threaded fasteners The stress was analyzed, and a simple and practical calculation formula for the bolt tightening torque was derived. The calculation method of the tightening torque was improved, and the theoretical calculation of the tightening torque was more comprehensively explained. However, regarding the bolt tightening of the diesel generator set connection box Research on the calculation of torque is relatively rare. Therefore, it is crucial to carry out relevant research on the calculation of the tightening torque of the connecting box bolts of diesel generator sets. Therefore, the force of the connecting box bolts is analyzed, the influencing factors of the connecting box bolt tightening torque are explored and the establishment of a diesel engine The calculation process of the tightening torque of the connecting box bolts provides a theoretical basis for the selection of the connecting box bolts and the calculation of the tightening torque of the diesel generator set.
