摘要： The present invention has an object to provide a balance shaft friction damper (1) capable of preventing a torque reduction of a lip sliding surface while ensuring an axial flow path for a lubricant to stably circulate the lubricant. The object is achieved by a balance shaft friction damper (1) including: a metal mounting ring (10) that is mounted in an annular gap (300) between a shaft portion (100) of a balance shaft of an engine and a gear portion (200) provided on an outer periphery of the shaft portion (100), and has a fitting surface (11a) fitted and secured to one of an outer peripheral surface (101) of the shaft portion (100) and an inner peripheral surface (201) of the gear portion (200); and an annular elastic ring member (20) made of a rubber-like elastic material and provided on the mounting ring (10), and has a lip sliding surface (21a) brought into close contact with the other of the outer peripheral surface (101) of the shaft portion (100) and the inner peripheral surface (201) of the gear portion (200), wherein an oil flow path portion (30) that allows axial circulation of a lubricant is formed in a position across the mounting ring (10) and the elastic ring member (20) and apart from the lip sliding surface (21a), and/or an oil flow path portion (30) that allows axial circulation of a lubricant is formed in a position in the mounting ring (10) and apart from the lip sliding surface (21a).

摘要： A method for securing a balancer shaft module to an engine is provided, the method including the steps of passing a mounting feature into at least two mounting apertures of the balancer shaft module; simultaneously rotating two of the mounting features within the mounting aperture, wherein the simultaneous rotation of the two mounting features laterally moves the balancer shaft module with respect to the engine; and securing the balancer shaft module to the engine. In addition, a mounting feature for securing a balancer shaft module to an engine is provided, the mounting feature having: a top portion; a mounting cylinder secured to the top portion, the mounting cylinder being centrally located on the top portion; a securement opening passing through the top portion and the mounting cylinder; and wherein the mounting cylinder has a non-uniform outer wall such that a center of the securement opening is offset from a center of the top portion such that rotation of the top portion rotates the securement opening about the center of top portion.

摘要： A balancing shaft (1) is proposed for compensating for mass forces and/or mass moments of an internal combustion engine, comprising an unbalance section (2) and a bearing journal (5, 6) for the radial mounting of the balancing shafts of the internal combustion engine, wherein the unbalance section and the bearing journal are produced separately from one another from different materials and are subsequently joined axially to one another by means of a torsionally stiff pin/hole connection. Here, the pin/hole connection is to be configured so as to act positively in the rotational direction of the balancing shaft and is to have two pins (8, 9, 10, 11) and associated holes (12, 13, 14, 15, 16, 17, 18, 19) which extend eccentrically with respect to the shaft axis (3).

摘要： A balancer mechanism is disclosed for a straight engine including an odd number of three or more cylinders, a crankshaft having a crank journal, crank arms spaced apart at a predetermined angular interval, a reciprocating portion and a rotating portion generating an inertia couple in the crankshaft, and a crank weight producing a combined inertia couple in the crankshaft by reducing some of the inertia couple. The axes of the cylinders are arranged offset with respect to the axis of the crank journal. The balancer mechanism includes a balance shaft and a balance weight arranged in the balance shaft in order to cancel the combined inertia couple. The phase of the rotation angle of the balance shaft with respect to the rotation angle of the crank journal is retarded by a predetermined angle with respect to such a reference phase that can cancel the combined inertia force in a case in which the axes of the cylinders cross the axis of the crank journal.
