Problems solved by technology

At present, the vibration of most shakers is realized by the crankshaft, with a single amplitude, and only a few oscillators are adjustable, such as the stepless adjustable amplitude mechanism of the culture oscillator (patent number: ZL201010150499.6), but its structure is complex , the adjustment mechanism always works in an oscillating environment, and its reliability is affected, which limits its scope of use to some extent

Embodiment 1

[0018] see Figure 1~Figure 4 , the circular oscillation mechanism with adjustable amplitude comprises a main shaft, a bearing fixing seat, a bearing, a driven shaft, an eccentricity adjustment pin, a pin shaft and a rocking plate, and is characterized in that: the main shaft is fixed on the main shaft fixing seat through a bearing and a bearing Above, one shaft end of the main shaft is connected with the transmission shaft driven by the variable speed motor, and the other end has a fixedly connected disc at the main shaft end through a pin shaft and an eccentricity adjustment pin to connect with a fixedly connected disc at the driven shaft end, and the driven shaft The other end of the shaft is fixedly connected with the rocking plate, which drives the rocking plate to perform circular motion; the end disc of the driven shaft can rotate a given angle around the pin shaft relative to the end disc of the main shaft, and the eccentricity adjustment pin can be changed by changing ...

Embodiment 2

[0020] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0021] The eccentric adjustment pin is a short shaft pin fixedly connected to the lower end of a waist block, the waist block is mated with a waist hole on the end disk of the driven shaft, and the short shaft pin is connected to an eccentric hole of the main shaft Mating, the connection position of the short shaft pin and the waist block is different, forming a replaceable eccentricity adjustment pin of different shapes; the end disc of the driven shaft can rotate around the pin shaft relative to the end disc of the main shaft. A certain angle, so that the axis of the driven shaft produces an eccentricity relative to the axis of the main shaft. The eccentricity also changes with the different rotation angles, and the shape of the eccentricity adjustment pin should also be changed accordingly to achieve a rigid connection between the two disc ends. .

Embodiment 3

[0023] Such as figure 1 As shown, the circular oscillation mechanism with adjustable amplitude includes a main shaft 1, a bearing holder 2, a bearing 3 and a bearing 4, a driven shaft 5, an eccentricity adjustment pin 6, a pin shaft 7 and a rocking plate 8, and is characterized in that: In the circular oscillation mechanism with adjustable amplitude, the main shaft 1 is fixed on the main shaft fixing seat 2 through the bearing 3 and the bearing 4, the small end of the main shaft 1 is connected with the transmission shaft driven by the variable speed motor, and the disc at the other end is passed through the pin shaft 6 The eccentricity adjustment pin 7 is connected with the end disk of the driven shaft 5, and the small end of the driven shaft 5 is connected with the rocking plate 8, which drives the rocking plate 8 to perform circular motion. The end disc of the driven shaft 5 can rotate around the pin shaft 6 by a certain angle relative to the end disc of the main shaft 1, an...

Abstract

The invention discloses an amplitude-adjustable circumferential oscillation mechanism. The amplitude-adjustable circumferential oscillation mechanism comprises a main shaft, a bearing fixing base, bearings, a driven shaft, an eccentric distance adjustment pin, a pin shaft and a swing plate. The main shaft is fixed to the main shaft fixing base through the two bearings. The small end of the main shaft is connected with a transmission shaft driven by a change-speed motor, and a disk at the other end of the main shaft is connected with the disc end of the driven shaft through the pin shaft and the eccentric distance adjustment pin. The small end of the driven shaft is connected with the swing plate to drive the swing plate to perform circumferential movement. The disc end of the driven shaft can rotate around the pin shaft by a certain angle relative to the disc end of the main shaft (1). The eccentric distance of the driven shaft relative to the main shaft can be adjusted by replacing eccentric-distance adjustment pins in different shapes, and therefore the amplitude of an oscillation device is adjusted. According to the amplitude-adjustable circumferential oscillation mechanism, rigid connection is reliable, any amplitude within the range from 0 mm to 50 mm can be achieved, and the application to the aspects such as bacterial culturing, fermentation, hybridization, biochemical reactions and enzyme and cell tissue researching with high requirements can be achieved.
