摘要： The invention is directed to a guide bar for guiding the saw chain of a motor-driven chain saw. The guide bar of the invention has a lamellar configuration and is not made of three parts as are conventional guide bars. Instead, the guide bar of the invention is made of two side parts. The two side parts are connected by means of spacers which are configured as projections on at least one of the two side parts. The side parts can be frames having large inner openings and are preferably stiffened. The connected frames define a composite frame which can be filled with plastic. The spacers determine the spacing of the side parts and therefore the width of the guide groove for the saw chain. The invention is also directed to a method of making the guide bar.

摘要： A guide bar for a motor-driven chain saw is disclosed wherein the guide bar is provided with a center cutout extending in the longitudinal direction of the bar which is filled out with a bonded fiber material made of plastic and reinforced with long fibers. The guide bar reduces the weight and facilitates manipulation of the chain saw equipped therewith while at the same time providing a high strength and the capacity to take up bending and torsion loads.

摘要： A guide bar for a motor chain saw has a guide bar member having a peripheral guide groove and peripheral shoulders for guiding a saw chain in the peripheral direction of the guide bar member. The drive members of the saw chain engage the guide groove and the lateral connecting members of the saw chain are guided on the shoulders. Wear protectors, made of a material that is more wear-resistant than the guide bar member, are provided. The wear protectors are connected to the peripheral shoulders so as to extend at least over a portion of the guide bar member in the peripheral direction. Each wear protector has a first wear surface facing the drive members of the saw chain and a second wear surface facing the lateral connecting members of the saw chain. At least one of the first and second wear surfaces of each wear protector has at least one peripheral recess extending in the peripheral direction.

摘要： The invention relates to a guide bar having a main member made of solid material for a motor chain saw. The guide bar has two flat sides and narrow edges defining a saw chain path. A cutout extends through the main member of the guide bar for reducing weight. The openings in the main member defined by the cutout are closed by cover plates for maintaining the stiffness and are attached to the main member of the guide bar. A fill body is seated in the cutout with an approximately precise fit and is connected to the cover plates in a force-transmitting manner. In this way, a higher torsion stiffness is obtained while at the same time retaining the reduction in weight.

摘要： The invention relates to a saw chain for a motor-driven chain saw equipped with a guide bar and a drive motor for imparting a force to the saw chain for moving the latter around the guide bar in a predetermined running direction. The chain saw is further equipped with a device for supplying lubricating oil to the saw chain during the movement thereof. The saw chain includes a plurality of cutting links, a plurality of driving links and a plurality of side links all pivotally interconnected by rivets. Abrasive small particles become entrained in the lubricating oil which can lead to premature wear at the pivot locations. The saw chain of the invention includes a hold-back element in front of a rivet to hold back such particles and yet not affect the flow of lubricating oil to the pivot connection.
摘要翻译：本发明涉及一种用于电动链锯的锯链，其具有引导杆和驱动马达，该驱动马达用于向锯链赋予力，以沿预定的行进方向将其围绕导杆移动。链锯还装备有用于在锯链运动期间向锯链供应润滑油的装置。锯链包括多个切割连杆，多个驱动连杆以及通过铆钉枢转地互连的多个侧链。研磨性小颗粒被夹带在润滑油中，这可能导致枢转位置处的过早磨损。本发明的锯链在铆钉前面包括一个夹持元件，用于阻挡这些颗粒，但不影响润滑油流向枢转连接。

摘要： A guide bar for a chain saw includes three layers. The two outer layers are defined by side plates which can be welded together by means of inserts and the intermediate member located therebetween is held in a form-tight manner by means of the inserts that are welded to the side plates. Because of this configuration, the intermediate member may be made of plastic or aluminum thereby reducing the weight of the chain saw. The guide bar with this sandwich configuration has excellent strength and has a weight less than conventional guide bars of comparable size.
