SPRING PLATE AND OVERRUNNING CLUTCH FITTED BY SPRING PLATE Russian patent published in 2014 - IPC F16D41/67 

FIELD: machine building.

SUBSTANCE: invention relates to a spring plate and an overrunning clutch fitted by the said spring plate. The spring plate consists of a supporting plate (3-1), a clamping plate (3-2) and a connecting bridge (3-3). The supporting plate (3-1) keeps a needle roller (2) suspended. The connecting bridge (3-3) couples the supporting plate (3-1) and the clamping plate (3-2). The clamping plate(3-2) is a straight plate (3-2-1) with V-shaped bends (3-2-2) on its ends. The spring plate is designed to be used in an overrunning clutch and is installed on its separator (1). The overrunning clutch also comprises a variety of needle rollers (2) and a variety of spring plates (3). The separator consists of the first and second ring-shaped end face walls (1-2), cross members (1-1) and an intermediate hole (1-3). Mounting slots for the spring plates (1-2-1) are set in places coinciding with each cross member (1-1), on the end face surface of the first and second ring-shaped end face walls (1-2) on both sides of the intermediate hole of the separator (1). The mounting slot base is of V-shape in the axial section of the separator (1). The inner surface of the straight plate (3-2-1) of the spring plate's clamping plate (3-2) corresponds to the outer surface of the cross member. The inner surface of the V-shaped bend (3-2-2) of the clamping plate (3-2) corresponds to the surface of the mounting slot base in a spring plate (1-2-1).

EFFECT: reduced risk of displacement and disconnection of a spring plate during the reciprocal motion of an overrunning clutch at high rotation speed and high frequency.
