EX200 Link Separate For HITACHI Excavator Undercarriage Link Parts

After the chain works for a period of time, wear causes the pin to become thinner, and the sleeve and rollers to become thinner. Under the action of the tensile load F, the chain pitch is extended.

　　After the chain pitch becomes longer, the pitch circle d moves toward the tooth top when  the chain is wound around the sprocket. Generally, the number of chain links is even to avoid the use of transition joints. In order to make the wear uniform and improve the service life, the number of teeth of the sprocket and the number of chain links should be mutually prime. If the quality is not guaranteed, the common factor should be made as small as possible.

　　The larger the chain pitch, the higher the theoretical carrying capacity. However, the larger the pitch, the greater the dynamic load caused by the change in chain speed and the impact of the chain linking into the sprocket, which will reduce the chain's bearing capacity and life. Therefore, a small-pitch chain should be selected as much as possible in design. The actual effect of selecting a small-pitch multi-row chain under heavy loads is often better than selecting a large-pitch single-row chain.

How to prevent slack in EX200 link separate

　　Our EX200 link separate will become loose or even disconnected in the case of long-term use and excessive wear. To prevent EX200 link separate, first of all, in order to prevent the wear and disconnection of EX200 link separate, we should improve the tension of EX200 link separate. In order to reduce its wear and tightness, we can choose a better quality EX200 link separate, which can improve the machining accuracy of the gear and the hardness of the working surface.

　　When we install EX200 link separate, we should install it in parallel with the EX200 link separate axis and properly calibrate it. This can effectively reduce the wear of the EX200 link separate. Otherwise, the deviation of the EX200 link separate and EX200 link separate axes will worsen the EX200. link separate wear and tear.

　　We have improved the tightness of the EX200 link separate. You can change the gold screws from two to four, which will make the operation lighter and increase the safety of the EX200 link separate operation.
