A gudgeon pin is also commonly known as a wrist pin which is one of the most important components in an internal combustion engine. BS 3537 discusses standards for Gudgeon pins. BS 3537 specifies dimensions, surface textures and other features of the design for various types of gudgeon pins, sometimes referred to as piston pins or wrist pins, all of which are case hardened. They are suitable for use in two and four-stroke cycle spark and compression ignition reciprocating internal combustion engines.
BS 3537 covers pins of 10 mm to 200 mm diameter. Typical applications of various types of gudgeon pins are given in BS 3537. BS 3537 also specifies the basic methods to be used for measuring the essential features of gudgeon pins. Although the gudgeon pins dealt with in BS 3537 are primarily intended for internal combustion engines, they may also be suitable for use in other types of machinery, for instance in reciprocating piston type compressors.
BS 3537 on Gudgeon pins is useful for:
In internal combustion engines, the Gudgeon pin connects the piston to the connecting rod and provides a bearing for the connecting rod to pivot upon as the piston moves. BS 3537 includes designs of gudgeon pins such as plain gudgeon pin, chamfer locking pin, button or end pad pin, clamp groove pins, and set screw location. BS 3537 introduces guidelines recommended for use of the classes of materials required to design gudgeon pins.
BS 3537 quantifies those aspects of quality most commonly encountered in gudgeon pin production which are not easily expressed in dimensional tolerances, including those for which no quantitative measuring procedures exist but which are only checked visually without the aid of magnification.
BS 3537 guidelines help to design and supply effective, high-quality and cost-effective Gudgeon pins up to 200 mm diameter with minimum or no manufacturing defects.
