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.

Embodiment Construction
[0022] Examples, see e.g. Figure 1 to Figure 5 As shown, a suspension shock-absorbing base of a motor includes four legs 1 and a base 2 formed on the motor casing, two of which are symmetrically arranged on the left side of the casing, and the other two legs 1 The front and back are symmetrically arranged on the right side of the housing, and the two left feet 1 and the right two feet 1 are symmetrically arranged left and right;
[0023] The support foot 1 is formed with a piston hole 11 with a lower side opening, and the base 2 includes four pistons 21 respectively inserted in the piston holes 11 of the four support feet 1. The piston 21 is fixed on the upper end of the push rod 22, the left side The lower ends of the two push rods 22 are respectively fixed on the front end and the rear end of the fixed plate 23 on the left side, and the lower ends of the two push rods 22 on the right side are respectively fixed on the front end and the rear end of the fixed plate 23 on the ...

The invention discloses a suspension-type damping pedestal of a motor. The pedestal comprises four support feet molded on a motor shell and the pedestal. Piston holes are formed in the support feet. The pedestal includes four pistons which are inserted into the four piston holes. The pistons are fixedly arranged on top rods. The four top rods are fixedly arranged on two fixing plates. The two fixing plates are fixedly connected by two extension rods. The left fixing plate is provided with two first oil channels. Each piston is provided with a second oil channel penetrating each top rod, and each second oil channel is connected with the corresponding first oil channel. A cavity formed by the pistons and the piston holes, the first oil channel and the second oil channel are filled with hydraulic oil. A compression spring sleeves the top rods, the compression spring presses against the pistons and a baffle plate, and the baffle plate is fixedly arranged on the support feet. The motor is suspended and connected to the pedestal through the support feet, which can effectively reduce vibration output by an explosion-proof motor to a device, effectively reduce generation of a noise, and increase a service life of the device.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a suspension-type shock-absorbing base of a motor. 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 with the equi...
