Description
Tool for applying locking moment Technical Field The invention relates to the field of bearing installation, in particular to a tool for applying locking moment. Background In the assembly process of mechanical equipment, the bearing is used as a core transmission part, the installation accuracy directly influences the operation stability, transmission efficiency and service life of the whole equipment, wherein the application of the bearing pre-tightening torque is a key procedure in the bearing assembly, the accuracy and stability of the locking torque directly determine the bearing pre-tightening effect, if the locking torque is insufficient, the problems of overlarge gap, aggravation of vibration, overlarge noise and the like can occur when the bearing runs, the bearing is worn and blocked in serious cases, if the locking torque is overlarge, the internal friction resistance of the bearing can be increased, the bearing aging is accelerated, even the bearing is deformed and damaged, the normal operation of the whole mechanical equipment is influenced, the manual operation of the whole mechanical equipment is usually finished by relying on manual operation of a torque wrench, the operation convenience is poor, when the locking torque to be applied is large, the single operation is difficult to reach the preset torque requirement, not only a large amount of labor cost is reduced, the assembly efficiency is also reduced, the control of the torque is mainly considered through the reading of the torque wrench, the accuracy is low, the deviation is easy to occur, and the tool is also required to be replaced according to the situation. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a tool for applying locking moment, which is more convenient to operate, higher in precision and better in applicability. In order to achieve the above purpose, the invention provides a tool for applying locking moment, which comprises a frame, wherein a transmission assembly and an adjusting assembly are arranged on the frame, the adjusting assembly comprises an adjusting sleeve barrel which is detachably arranged, an installing rod and a moment inductor with a display screen, the adjusting sleeve barrel is used for being meshed with a locking nut, the adjusting sleeve barrel is detachably arranged, the installing rod extends to the upper end of the frame, the installing rod is used for being in clamping sleeve fit with a mandrel, and the transmission assembly comprises an output shaft for driving the adjusting sleeve barrel to rotate. The technical scheme has the advantages that the transmission assembly and the adjusting assembly are arranged on the frame, the mandrel and the bearing which need to be pre-tightened are arranged on the mounting rod, the adjusting sleeve which is used for meshing the locking nut is driven by the output shaft of the transmission assembly to rotate, the manual application of the locking moment of the bearing is replaced, the labor cost is effectively saved, the assembly efficiency is improved, the adjusting assembly is provided with the moment inductor with the display screen, the locking moment value can be displayed in real time, the precise pre-tightening moment is convenient to control, the bearing assembly quality is guaranteed, meanwhile, the adjusting sleeve is detachably arranged, the mounting rod and the mandrel form sleeve fitting, the locking nuts and the mandrel with different specifications can be matched, the universality and the suitability of the tool are greatly improved, and the locking moment application requirements of different bearing assemblies are met.
