The invention relates to the technical field of direct current motors, and discloses a fast-installable direct current motor with a shock-absorbing effect, comprising a bottom plate, the bottom of the bottom plate is fixedly connected with a buffer layer, and the inner thread of the buffer layer is connected with fixing bolts , the top of the base plate is fixedly connected with a card frame, the top of the card frame is clipped with an upper cover, the internal thread of the card frame is connected with a mounting bolt extending to the inside of the upper cover, and the left wall of the upper cover is fixed Connected with bearing housing. The quick-installable DC motor with a shock-absorbing effect buffers the vibration generated by itself through the reverse resistance generated by the shock-absorbing spring when the DC motor body vibrates against the first shock-absorbing tube and the second shock-absorbing tube, In addition, the inner bearing is sleeved on the outside of the rotating shaft, which can make the rotating shaft stable and the vibration is small when rotating, thus effectively solving the problem that the DC motor will generate large vibration during use, and long-term use will affect itself. .

The invention provides a three-phase five-column type amorphous alloy transformer. The three-phase five-column type amorphous alloy transformer comprises an amorphous alloy, a coil, a clip, a transformer frame and a transformer tank, wherein the clip is divided into an upper clip, a lower clip and a side clip; the transformer further comprises a noise reducing device; the noise reducing device comprises a strengthening bar and a shock-absorbing device; the shock-absorbing device is divided into a first shock-absorbing device and a second shock-absorbing device; the second shock-absorbing device comprises a lower fixing plate and lower shock absorbers; the lower fixing plate is connected with the transformer tank via the lower shock absorbers; a shock-absorbing cavity is disposed on the lower fixing plate; the lower shock absorbers are disposed inside the shock-absorbing cavity; the number (N) of the the lower shock absorbers at the bottom of the lower clip is no less than three; the central location of the bottom of the transformer frame is provided with the lower shock absorber all the time; and the rest of the shock absorbers are centrally symmetric in distribution with respect to the central shock absorber. According to the transformer provided by the invention, the shock passing between the amorphous alloy and the transformer tank is reduced to the maximum by adopting multiple shock absorption, and the anti-shock performance of the noise-reducing device is effectively improved; and the assembling of the shock absorbing device is simple and easy.

The invention relates to a cylinder-type shock absorbing device, which belongs to the field of machinery. The device includes a cylinder body, a support plate, a SAW acceleration sensor, a shock-absorbing spring, an upper piston, a middle partition, a lower piston, a conductor assembly and a permanent magnet; the upper The piston is connected to the support plate through the piston rod; the SAW acceleration sensor is set under the support plate; the shock-absorbing spring ring is set outside the piston rod and between the support plate and the upper wall of the cylinder; the middle partition is welded on the inner wall of the cylinder; A damping channel is set on the middle partition, a stepping motor is set inside, and a damping adjustment plate is set on the top; the bottom of the lower piston is connected to a conductor assembly, which is connected to an external resistance through a wire; the conductor assembly is located in the magnetic field generated by the permanent magnet. The device can convert part of the mechanical energy into electric potential energy and consume it in the thermal energy of the metal conductor and the protective resistor, and convert the other part of the energy into the thermal energy between the hydraulic oil, the cylinder wall and the damping channel, thereby realizing three-part shock absorption, making the vibration The effect is more efficient.
