Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a motor for engineering machinery. Background Art

[0002] Engineering machinery is an important part of the equipment industry. Generally speaking, all mechanical equipment required for earthwork construction, road construction and maintenance, mobile lifting and loading and unloading operations, and comprehensive mechanized construction projects required for various construction projects are called engineering machinery.

[0003] During the operation of engineering machinery, due to the extremely harsh working environment, the protection level of its motor is required to be extremely high. In the prior art, the motor is generally protected from vibration during operation by a shock-absorbing base on the motor. However, the existing motor shock-absorbing base has a single structure and is generally treated by a unidirectional shock-absorbing spring and a damping component. For example, the utility model patent with the publication number CN210693644U discloses a high-voltage motor assembly, specifically a high-voltage motor shock-absorbing base, which includes a cylindrical shell, and strip plates are provided on both sides of the bottom of the shell. The characteristic is that there is a bottom plate below the strip plate, and the two end surfaces of the bottom plate are respectively flush with the outer side surfaces of the two strip plates. The four corners of the upper surface of the bottom plate are provided with vertically arranged connecting rods, and the strip plates corresponding to the connecting rods are provided with through holes. The upper end of the connecting rod passes through the corresponding through hole and extends above the strip plate.

[0004] The above-mentioned prior art can eliminate the vibration generated by the motor through the deformation of the shock-absorbing spring during use. However, the shock-absorbing spring is mounted on the connecting rod, so it can only buffer the vibration in the direction of the connecting rod and is not convenient for eliminating vibration in other directions.
