Abstract

The invention discloses a cylinder type self-balancing eccentric shaft. A center line of a connecting guard in the eccentric shaft is originally arranged together with a center line of eccentric bearing guards in the same direction (or coincides with a rotary center line) but is currently arranged in the opposite directions, and self-balancing of the eccentric inertia spin moment of the eccentric shaft is achieved by utilizing the opposite eccentric inertia moment balance principle. The eccentric inertia spin moment of the eccentric shaft in the prior art is self-balanced by the interior of the eccentric shaft instead of original external flywheels, thus eccentric balance weights on the external flywheels can be omitted. The cylinder type self-balancing eccentric shaft has high balance precision and a simplified structure, is easy to detect and control, reduces the manufacturing cost of equipment and saves the operating cost.

Description

technical field

[0001] The invention relates to the technical field of jaw crushers, in particular to a cylindrical self-balancing eccentric shaft for jaw crushers. Background technique

[0002] Jaw crusher, commonly known as jaw crusher, is one of the oldest and most widely used crushing equipment. The eccentric shaft is the core part of the jaw crusher equipment. The jaw plate in the jaw crushing pair is tightened and loosened when crushing materials, which comes from the eccentric design of the eccentric shaft.

[0003] Prior art eccentric shafts have two centerlines (see figure 1 ): ① Rotation center line, that is, the center line where the axes of the concentric bearing gear, locking gear and reference gear are located; ② Eccentric center line, that is, the center line where the axes of the eccentric bearing gear and the connecting gear are located. The working mechanism of the eccentric shaft is: when the motor is connected with the flywheel on the reference gear thr...
