Crankshaft thrust plate

The utility model discloses a crankshaft thrust plate which comprises an upper thrust plate and a lower thrust plate, and the upper thrust plate and the lower thrust plate are the same in structure. An oil groove is formed in the upper thrust plate and comprises a first rectangular groove, a second rectangular groove, a third rectangular groove and a trapezoidal groove; a positioning block is arranged on the outer circle face of one end of the upper thrust plate, a semicircular groove is formed in one end of the positioning block, and a semicircular flange is arranged at the other end of the upper thrust plate. The problem of misloading of the thrust plate can be solved, the abrasion of an alloy layer of the thrust plate is effectively reduced, the applicability is high, the lubricating effect is improved, and the service life is prolonged. 本实用新型公开了一种曲轴止推片，包括上止推片和下止推片，所述上止推片和下止推片结构相同；所述上止推片上设置油槽，所述油槽包括第一矩形凹槽、第二矩形凹槽、第三矩形凹槽、梯形槽；所述上止推片一端的外圆面设置定位块，所述定位块的一端设置半圆形凹槽，所述上止推片另一端设置半圆形凸缘。能够解决止推片错装的问题，有效的降低止推片合金层的磨损，适用性强，
