WHITTET-HIGGINS防松螺母AN系列產(chǎn)品介紹
Most commonly used locknuts, made of low carbon steel, these locknuts are the least expensive but require a lockwasher and the cutting of a keyway in the shaft.
This series meeting SAE-Society of the Automotive Engineers, ABEC-Annular Bearing Engineers Committee and AFBMA- Anti-Friction Bearing Manufacturers Association specifications offers a positive mechanical lock when combined with a lockwasher and keyway.
An 'A' before the locknut designation indicates this size was previously manufactured with 11 threads per inch whereas now they have either 12 or 8 threads per inch. It is recommended that everyone avoid making shaft threads to this now semi-obsolete 11 pitch series. All new designs could best use the 12 and 8 pitch AN series of threads for the greatest assurance of long term compatibility and future availability.
This N-AN series through size AN-26 meets the many exacting requirements for good operation of tapered roller bearings but series PN in all sizes meets specifications for the safest and best operation of tapered roller bearings.
最常用的鎖緊螺母，由低碳鋼制成，這些鎖緊螺母最便宜，但需要鎖緊墊圈和軸上的鍵槽切割。
該系列符合 SAE-汽車工程師協(xié)會(huì)、ABEC-環(huán)形軸承工程師委員會(huì)和 AFBMA-減摩軸承制造商協(xié)會(huì)的規(guī)范，在與鎖緊墊圈和鍵槽結(jié)合時(shí)提供了一種正向機(jī)械鎖。
鎖緊螺母名稱前的“A”表示該尺寸以前制造時(shí)每英寸有 11 個(gè)螺紋，而現(xiàn)在每英寸有 12 或 8 個(gè)螺紋。建議大家避免為這個(gè)現(xiàn)在半過(guò)時(shí)的 11 節(jié)距系列制作軸螺紋。所有新設(shè)計(jì)都可以最好地使用 12 和 8 節(jié)距 AN 系列螺紋，以最大程度地保證長(zhǎng)期兼容性和未來(lái)可用性。
該 N-AN 系列至 AN-26 尺寸滿足圓錐滾子軸承良好運(yùn)行的許多嚴(yán)格要求，但所有尺寸的 PN 系列均滿足圓錐滾子軸承最安全和最佳運(yùn)行的規(guī)范。
