Problems solved by technology

However, the existing explosion-proof motors generally have no shock-absorbing measures. When the explosion-proof motor is installed on equipment such as fans and compressors, the vibration generated is relatively large, and it is easy to resonate with the equipment connected to it, reducing the service life of the equipment. Noisy

Embodiment Construction

[0021] Examples, see e.g. Figure 1 to Figure 5 As shown, an explosion-proof motor provided with a shock-absorbing base includes an explosion-proof motor 1, and two left and right symmetrical legs 2 are formed on the shell of the explosion-proof motor 1, and the shock-absorbing legs 2 are formed with a lower opening. The hole 21 is sealed with a mandrel 3 in the shock-absorbing hole 21, and the mandrel 3 is fixed at both ends of the bottom plate 4, and the shock-absorbing chamber formed by the shock-absorbing hole 21 and the mandrel 3 is filled with hydraulic oil 6;

[0022] The outer wall of the lower end of the support foot 2 is formed with a plurality of circumferentially evenly distributed lugs 22, and the lugs 22 are formed with through holes 23 that penetrate up and down. Large and small step through holes 41; the small end hole of the step through hole 41 is sleeved with a pull rod 51, and the end of the pull rod 51 extending into the large end hole of the step through ...

Abstract

The invention discloses an explosion-proof motor having a shock absorption base. The explosion-proof motor having a shock absorption base comprises an explosion-proof motor. Two bilaterally symmetrical support legs are disposed on the housing of the explosion-proof motor. Shock absorption holes are disposed on the support legs. Mandrels are sealed in the shock absorption holes and are fixed to both ends of a bottom plate. The shock absorption cavities formed by the shock absorption holes and the mandrels are filled with hydraulic oil. The support legs are fixedly connected with the bottom plate. The shock is absorbed by the hydraulic oil between the support legs and the bottom plate, thereby effectively reducing the vibration of the explosion-proof motor output to a device and reducing thenoise.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an explosion-proof motor provided with a shock-absorbing base. Background technique [0002] Explosion-proof motor is a kind of motor that can be used in flammable and explosive places, and does not generate electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, it is also widely used in textile, metallurgy, city gas, transportation, grain and oil processing, papermaking, medicine and other departments. As the main power equipment, explosion-proof motors are usually used to drive pumps, fans, compressors and other transmission machinery. However, the existing explosion-proof motors generally have no shock-absorbing measures. When the explosion-proof motor is installed on equipment such as fans and compressors, the vibration generated is relatively large, and it is easy to resonate w...
