Amplification device for converting low-frequency motion into high-frequency motion

Abstract

The invention discloses an amplifying device for converting low-frequency motion into high-frequency motion. Comprising a lower base, an upper base and a screw rod, the lower base comprises a lower bottom plate and a support, an annular groove is formed in the upper surface of the support, a plane thrust ball bearing is installed in the annular groove, the other end of the plane thrust ball bearing is sleeved with a large gear, a lower ratchet wheel is arranged on the upper end face of the large gear, and a plurality of corresponding deep groove ball bearing holes are evenly formed in the lower surface of the upper base. A plurality of columnar cam shafts are arranged between the upper base and the lower bottom plate and around the periphery of the support, small gears are arranged at the positions, corresponding to the large gears, of the middles of the cam shafts, the upper base is sleeved with an upper protection shell, and the lower base is sleeved with a lower protection shell. The amplitude after the frequency is increased is controlled by changing the maximum radius and the minimum radius of a cam in the device, and the amplitude of object movement can be accurately controlled; and the movement of the object in the vertical direction can be changed into the movement in the horizontal direction.

Description

technical field [0001] The invention belongs to the technical field of mechanical motion frequency amplifying devices, and in particular relates to an amplifying device for converting low-frequency motion into high-frequency motion. Background technique [0002] There are many low-frequency movements in nature, such as: human body walking, car vibration, etc. At this stage, there are not many motion devices that can convert these low-frequency movements into high-frequency ones. [0003] At present, there are mainly frequency-up devices composed of cantilever arms and mass blocks, and structures that use magnets to increase frequency. These structures do increase the frequency of motion and vibration to a certain extent, but they are uncontrollable for the frequency of the increase. After the frequency is increased, the amplitude of the object's motion cannot be accurately calculated. Therefore, these structures have the defect that the data cannot be calculated objectivel...
