摘要： A roller assembly for a diesel engine used in a high mileage vehicle includes a roller having an exterior roller surface and an interior surface that defines a bore extending therethrough. A pin is positioned in the bore and defines an exterior pin surface. A plurality of rolling elements is positioned between the exterior pin surface and the roller interior surface. Each of the rolling elements rollingly engages the exterior pin surface and the roller interior surface. The roller assembly defines a clearance of between about 0.01 mm to about 0.03 mm between the rolling elements, the exterior pin surface and the interior surface. The roller assembly is configured to achieve extended life criteria wherein the clearance does not increase to more than 0.02 mm to 0.06 mm after 500,000 miles of travel of a vehicle powered by a diesel engine having the roller assembly installed therein.

摘要： A high-pressure oil pump roller tappet, used for automobile fuel injection system, mounted between the driving cam and the tappet. The roller tappet includes a shell, a holder, a roller, and a pin. Planes A are arranged on both sides of the seam on lateral sides of the shell. Holes I are arranged at symmetrical positions on two planes A. Holes II are arranged on symmetrical positions on vertical plates. The roller is located in the middle of the pin. Welding has no requirement on the thickness of the plate. The weight can be controlled effectively, reducing inertia force, friction, and wear, improving engine efficiency. The shell and holder are designed as being separate, ensuring that the shell subjects to lateral force as little as possible when the holder subjects to a force, such that the shell is less likely to vibrate. Thus, the shell avoids the abrasion.
摘要翻译：用于汽车燃油喷射系统的高压油泵滚轮挺杆安装在驱动凸轮和挺杆之间。滚子挺杆包括壳体，支架，滚子和销。平面A布置在壳体侧面的接缝的两侧。孔I布置在两个平面A的对称位置上。孔II布置在垂直板上的对称位置上。滚轮位于销钉的中部。焊接对板的厚度没有要求。可以有效控制重量，减少惯性力，摩擦和磨损，提高发动机效率。外壳和支架被设计成分离的，以确保当外壳承受力时，外壳承受尽可能小的横向力，使得外壳不太可能振动。因此，壳避免了磨损。

摘要： In one aspect, the present disclosure is directed to a tappet assembly for a machine. The assembly may include a tappet body, a pin fixedly mounted in the tappet body, and a substantially cylindrical roller mounted about the pin. The roller may have a substantially cylindrical outer surface with a circumferential dimension and a width dimension, the width dimension being defined by two lateral edges. The roller may be configured to provide rolling contact between the outer surface of the roller and a cam lobe. The outer surface of the roller may be crowned such that at maximum operational loading conditions of the machine a footprint of contact pressure from the cam lobe is spread substantially the full width of outer cylindrical surface of the roller.
