Abstract

The invention discloses an adjusting mechanism for the eccentric radius of an eccentric crankshaft. The adjusting mechanism is characterized by comprising the eccentric crankshaft, eccentric circular rings, fixed screws and connecting bearings. An eccentric circle and a lower eccentric circle, which are symmetrically arranged, are mounted on the eccentric crankshaft. The two eccentric circular rings are respectively assembled on the two eccentric circles in a clearance fit manner, and can rotate oppositely. The eccentric circular rings and the eccentric circles are fixed through the fixed screws. The eccentric circular rings are respectively matched with the corresponding connecting rod bearings. The two ends of the eccentric crankshaft are respectively matched with crankshaft fixed mounting bearings. The eccentric radius is changed by adjusting the radial relative positions of the eccentric circular rings and the eccentric crankshaft so as to change the vibration amplitude, the adjusting mechanism is simple, and convenient to adjust, the vibration amplitude can be randomly adjusted within a certain range, self locking is guaranteed to be realized in operation by fastening the fixed screws, the safety of a device is ensured, the adjusting precision of the device is improved, and the service life of the device is prolonged. The adjusting mechanism has not been used on a tobacco shred vibrating screen, and also has not been used in other industries.

Description

technical field [0001] The invention relates to the adjustment of an eccentric crankshaft, in particular to an eccentric radius adjustment mechanism of an eccentric crankshaft, which can arbitrarily change the amplitude of eccentric vibration within a certain range. Background technique [0002] The eccentric crankshaft eccentric radius adjustment mechanism is the adjustment of the vibration amplitude on the equipment and instruments that use the eccentric principle to vibrate. It can accurately adjust the size of the vibration amplitude within a certain range, and ensure that the vibration eccentric angle has only a small change. For equipment and instruments that vibrate using the eccentric principle, the amplitude is the core issue, so the eccentric radius adjustment mechanism of the eccentric crankshaft plays an important role in the vibration industry. [0003] Traditional eccentric vibration equipment does not have the function of adjustable amplitude. Due to design ...
