Abstract

The invention discloses a hydraulic ball type sectional soft start and overload protection device. The hydraulic ball type sectional soft start and overload protection device comprises a jaw crusher frame, an eccentric shaft mounted on the frame, a flywheel and a belt wheel, wherein the belt wheel is idly mounted on the eccentric shaft through a first bearing bush; a driven ball bearing disc is idly mounted on the eccentric shaft through a second bearing bush; the belt wheel is connected with a driving ball bearing disc; a separation spring is arranged between the driving ball bearing disc and the driven ball bearing disc; eight square ball holes are respectively formed in the end surfaces of the driving ball bearing disc and the driven ball bearing disc; driving force conveying steel balls and driven force conveying steel balls are respectively loaded into the ball holes; the ball holes are respectively sealed with driving ball collecting rings and driven ball collecting rings; the peripheral surface of the driven ball bearing disc is connected with a transmission sleeve and an annular oil cylinder through splines; and annular pistons capable of butting against one side end surface of the driven ball bearing disc are mounted in the transmission sleeve and the annular oil cylinder. The hydraulic ball type sectional soft start and overload protection device has the advantages of reliable operation, sensitive response to overload, quick clutch, convenience for discharging complete objects and low cost.

Description

technical field [0001] The invention relates to a mechanical protection device, in particular to a hydraulic ball-type segmented soft start and overload protection device and a control system thereof applied to a jaw crusher. Background technique [0002] Jaw crusher is a kind of engineering machinery widely used in mineral processing, building materials, silicate and chemical industries. Such as figure 1 As shown, the crushing of materials is carried out between the movable jaw plate and the fixed jaw plate. The movable jaw plate swings periodically to the fixed jaw plate around the suspension mandrel. When the movable jaw is close to the fixed jaw, the ore located between the two jaws is crushed. When the movable jaw leaves the fixed jaw plate, the crushed ore will be discharged through the ore discharge port under the action of gravity. At present, there are only two types of jaw crushers that are most widely used: the jaw crusher with a crank double rocker mechanism ...
