Technical Field
[0001] The utility model belongs to the technical field of equipment maintenance, in particular to a dynamometer bearing assembly tool. Background Art
[0002] When repairing and replacing the rotor bearing of the dynamometer, it is necessary to ensure the bearing sinking amount. Since the dynamometer housing itself has no limit point, the sinking amount cannot be accurately controlled when the bearing is pressed. If the sinking amount is small, it will not meet the working needs. If the sinking amount is large, the bearing end face fits the housing, the bearing will not be able to rotate normally, and the oil filling cavity space will also be compressed. At the same time, the bearing is installed with an interference fit. After the bearing is disassembled once, it cannot be used a second time. Because the bearing adopts an interference fit, each disassembly and assembly operation is extremely difficult. If the installation is not standard, it will greatly affect the maintenance efficiency of the equipment, and will damage the replacement parts and increase the equipment maintenance cost. Therefore, a maintenance and assembly tool that can perform standard installation of the dynamometer rotor bearing is needed. Summary of the invention

It can ensure that the bearing can be assembled into place in a single time, ensure smooth installation and improve installation quality and efficiency.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a dynamometer bearing assembly tool, including a knocking sleeve, a limiting ring, an inner ring bearing seat and an outer ring bearing seat; the knocking sleeve is detachably fixedly arranged on one side of the operating end of the limiting ring, and the bearing seat is detachably arranged on one side of the working end of the limiting ring, the working end face of the bearing seat is fitted against the end face of the bearing to be installed, and the bearing to be installed can be installed in a suitable position by knocking the rear end of the knocking sleeve, the bearing seat is divided into an inner ring bearing seat and an outer ring bearing seat, and the inner ring bearing seat and the outer ring bearing seat are alternately installed on the limiting ring according to the working conditions.
[0005] The beneficial effects of the utility model are as follows: the tooling assembly is provided with a knocking sleeve, a limit ring and a bearing seat, and the bearing can be accurately installed on the dynamometer through a simple combination connection, and the structure is streamlined and easy to use; the tooling is preset with bearing seats of various sizes, and can be adapted to install bearings of various structural shapes, with high flexibility and strong practicality; the tooling is simple to operate and has high maintenance and use efficiency; because of the accurate installation of the bearing and high success rate, the equipment maintenance cost is effectively controlled.
