· Cone Crusher Eccentric, Gears, Pinion-shaft. The eccentric is made of high carbon cast steel and fitted with a bronze inner wearing sleeve. The eccentric turns in a bronze bottom shell bushing. Both sleeve and bushing are replaceable. The eccentric throw can be changed in the field by installing a different sleeve.
· The single-toggle crusher is also known as an overhead eccentric for its eccentric shaft is up above compared to the Dodge which has its shaft below/under. Here, the eccentric is integrated into the "swing" jaw plate that''s moving up/down as the flywheel rotated by the motor.
If the eccentric shaft of jaw crusher appears severe wear, we can adopt the following fixes. Polishing the abrasive shaft neck, control the surface roughness and processing capacity. Then put the size of shaft neck as reference to mate a bearing. Using electric arc to weld journal surface, then cut to achieve the desired size of shaft neck.

Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always). Cone Crusher Components. The main components of a cone crusher include the main shaft, mantle, concaves, cone, eccentric bushing, drive, crown gear, frame, and tramp release mechanism (mechanically or hydraulically actuated).
Eccentric motion is achieved by the lower eccentric bushing and drive arrangement on the bottom of the main shaft. The input pinion drive countershaft is supported by pinion bearings and powered by an electric motor. An external gearbox or belt drive arrangement reduces the motor speed to approximately 100-200 RPM at the crusher.

When the eccentric shaft is installed, the boss of the lower* pad is clamped in the groove of the bottom cover to be secure. The upper* pad of the conical crusher thrust bearing is fixed on the ...
A gyratory crusher includes an anti-spin mechanism which couples a lower end of the eccentric shaft of the crusher to the stationary frame of the crusher so as to prevent the eccentric shaft and associated crushing head from spinning when the crusher is not subject to a crushing load. The anti-spin mechanism includes 1) a gear train preferably formed from two sets of intermeshing gears, and 2 ...
· Movable jaw crusher jaw plate movement is the eccentric rod, and thrust with the board to achieve, It is by the flywheel, eccentric shaft, connecting rod, thrust plate and thrust board (known as cubits after board) composition. Two flywheels are mounted on both ends of the eccentric shaft. Eccentric shaft supported on bearings on the wall rack.
In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw. A double toggle crusher has, basically, two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an ...

Eccentric shaft with counterweight …. On an eccentric shaft having at least one counterweight (20) which is mounted to the shaft as separate part, the seat of the ...
· The eccentric shaft is driven by a V-belt drive, with the inertia of two flywheels mounted onto the shaft accumulating crushing energy (see Figure 1). The kinematic principle applied in the ERC ensures the stroke remains the same throughout the entire crushing chamber.
The eccentric shaft is in poor contact with the copper bush of the frame, including: There is foreign matter in the eccentric shaft positioning hole of the cone crusher. The lower end of the eccentric shaft does not match the size of the location on the upper surface of the thrust bearing.
· 1. Cause analysis of eccentric shaft fracture of Vibrating Screen. (1) According to industry data and user usage, the service life of eccentric shaft is generally 1-2 years. If the time is too long, the eccentric shaft may break due to fatigue failure due …
In a typical jaw crusher, two outer bearings located on either side of the main frame support an eccentric shaft, while two inner bearings support a movable jaw. These are commonly known as "Pitman" bearings. The reciprocating motion of the shaft moves the Pitman against a …
· The eccentric shaft is made of Alloy Steel Fitted with anti-friction bearings and is in the pitman and dust proof housing. 6. Flywheel. The rotational energy is fed into the eccentric shaft of the jaw crusher by means of a sheave pulley which usually has multiple V-belt grooves. In addition to turning the pitman, eccentric shaft usually has ...
· Single-toggle jaw crushers (also known as overhead eccentric crushers) operates with its eccentric shaft above it. In here, the eccentric is built into the the swing jaw plate that moves in an up and down motion as the flywheel is rotated.

Eccentric Shaft Function. Jaw crusher eccentric shaft plays an quite important role in jaw crusher operating. The pitman is put in motion by the oscillation of an eccentric lobe on a shaft that goes through the pitman''s entire length. This force is also put on the shaft itself so they are constructed with large dimensions and of hardened steel.
As we know, jaw crusher is a kind of mining equipment that is very important. The equipment stands wear and tear, however it''s not all. Eccentric shaft is one of the main vulnerable parts of jaw crusher. If jaw crusher fails to work caused by abrasive eccentric shaft, users would have no idea because they learn little about the maintenance and repairment of jaw crusher.
Therefore, the eccentric shaft of the jaw crusher must have better abrasion resistance. Some jaw crushers, the dynamic jaw axis and moving jaw connection is the use of double tangential key connection method, the advantages of this method is easy to disassemble. And the whole jaw crusher, this jaw crusher eccentric shaft is not so good demolition.
