    • The invention relates to a lock washer (39) comprising two rings of teeth (10, 26) each having a bearing face (11, 11'), said bearing face having a plurality of asymmetric radial teeth (16, 16'), each of said asymmetric teeth having, on the one hand, a crest (20, 20') and a root (18, 18') spaced angularly away from said crest, and secondly an inclined slippage flank (22, 22') extending angularly between said crest (20, 20') and said root (18, 18'), the bearing faces (11, 11') of said rings of teeth being able to press against one another, whereas said slippage flanks (22, 22') come respectively into contact with one another along a contact surface. Said bearing face (11') of at least one of said rings of teeth (26) has an indentation (28) to reduce the area of said contact surface of said slippage flanks (22, 22').
    • 本发明涉及包括两个齿环(10,26)的锁紧垫圈(39),每个齿具有支承面(11,11'),所述支承面具有多个不对称的径向齿(16,16'),每个 所述不对称齿一方面具有角度远离所述顶部间隔开的顶部(20,20')和根部(18,18'),并且其次具有倾斜延伸的倾斜滑动侧面(22,22'),所述倾斜滑动侧面 所述顶部(20,20')和所述根部(18,18')之间,所述齿圈的支承面(11,11')能够相互压靠,而所述滑动侧面(22,22') 沿着接触表面分别彼此接触。 所述环齿(26)中的至少一个的所述支承面(11')具有凹口(28)以减小所述滑动侧面(22,22')的所述接触表面的面积。

    • A method for producing metallic washers (1) for locking in bolted joints, a washer having an annular configuration and on one side (9) a pattern of radially extending cams (10) and on the other side having a pattern of radially extending teeth (3), the washers on at least the side (2) having the pattern of teeth having a surface with a hardness preferably exceeding the hardness of the material to interact with the washer pattern of teeth in a locking operation. The method is especially characterized in the steps of-coating a batch of washers (1) with a corrosion resistant outer surface layer (7), the hardness of which exceeding the hardness of the material (6) to interact with the washer pattern of teeth (3) in a locking operation. The present invention also relates to a washer and a plant.
    • 一种用于制造用于锁定螺栓接头的金属垫圈(1)的方法,具有环形构造的垫圈和在一侧(9)径向延伸的凸轮(10)的图案,并且在另一侧上具有径向延伸的齿的图案 如图3所示,至少具有牙齿图案的侧面(2)上的垫圈具有在锁定操作中硬度优选地超过材料的硬度以与垫圈图案相互作用的表面的表面。 该方法的特征在于以下步骤:用耐腐蚀的外表面层(7)涂覆一批垫圈(1),其硬度超过材料(6)的硬度以与牙齿的垫圈图案相互作用 (3)锁定操作。 本发明还涉及洗衣机和植物。
