Description

Technical Field

[0001] The utility model relates to the technical field of motors, and particularly relates to a motor with good impact resistance effect. Background Technique

[0002] As a power component, a motor provides power output for other devices. When the motor is in use, the motor is first fixed on other mechanical devices, and then the motor is started. The rotation of the output shaft of the motor drives the operation of other mechanical devices.

[0003] After retrieval, a generator cover with an impact-resistant structure, with the publication number CN202110966291.X, includes a rear end cover and an impact-resistant component. An outer pressure-resistant component is arranged on the outer side of the rear end cover, and an installation and fixing component is arranged around the outside of the rear end cover. The installation and fixing component includes a connecting convex plate, a movable shaft, a fixed connecting rod, a positioning plate and a positioning hole. The movable shaft is rotatably arranged inside the connecting convex plate, and the fixed connecting rod is connected to the outer side of the movable shaft. The end of the fixed connecting rod is fixed with the positioning plate, and the positioning hole is arranged inside the positioning plate. The impact-resistant component is arranged on the outer end face at the rear of the rear end cover and the outer side of the outer pressure-resistant component. The impact-resistant component includes an outer airbag, an upper airbag, side airbags, a fixed connecting pipe and an inflation port. The outer airbag is fixedly connected to the rear end cover, and the inflation port is arranged on the lower side of the outer airbag. The upper airbag and side airbags are respectively fixed on the upper side and the left and right sides of the outside of the outer pressure-resistant component, and the upper airbag and side airbags are both connected to the outer airbag by the fixed connecting pipe. The generator cover with the impact-resistant structure is provided with an outer pressure-resistant component. Rubber bumps with a hemispherical flexible structure are evenly distributed between the pressure-resistant cover layer and the rear end cover, and can play a role in pressure resistance inside the pressure-resistant cover layer. Its hemispherical shape can bounce back the pressure, so the pressure resistance is better. The setting of the buffer spring can further play a role in earthquake resistance and pressure reduction, so that the pressure-resistant cover layer can fully protect the rear end cover on its outer side. When the existing motor works while being installed on the shell of other equipment, it is easily impacted by foreign objects, causing the internal parts of the motor to become loose or damaged, resulting in the motor being unable to work properly.
