Description

Novel vibrating screen motor seat Technical Field The utility model relates to the field of industrial screening equipment, in particular to a novel vibrating screen motor seat. Background The vibrating screen is used as key equipment in the field of industrial screening, and the stability of a vibrating motor of a core driving component directly determines screening efficiency and equipment service life. The motor seat is used as a supporting and driving structure of the vibration motor, needs to bear high-frequency vibration load and periodical torque impact, and is particularly important in design rationality. The motor seat of the traditional vibrating screen adopts a single main shaft connection mode, and the vibrating motor is fixed through a rigid bracket. However, long-term high-frequency vibration exposes the following core problems: And the main shaft is subjected to fatigue fracture, namely a single main shaft structure is easy to generate local stress peak values under the continuous alternating stress effect due to concentrated stress, so that fatigue cracks are initiated and expanded. Particularly when the main shaft material is plain carbon steel or is not subjected to surface strengthening treatment (such as nitriding and shot blasting), the fatigue resistance is obviously insufficient. The vibration adjustment is limited because the traditional motor seat adopts a fixed layout, only can provide limited vibration parameter adaptation capability, and lacks a buffer structure, so that vibration energy is directly transmitted to the base, and the integral vibration noise and structural damage of the equipment are aggravated. The above problems severely restrict the long-term stable operation and screening efficiency of the vibrating screen. Therefore, a new motor seat is needed to fundamentally solve the core defect of the conventional technology. In view of the above, there is a need in the art for improvements.
