    انواع بلبرینگ

    امروزه برینگ ها در انواع مختلف و در ابعادی بسیار وسیع در سراسر دنیا تولید می شوند. برینگ همان صورت فارسی Bearing است که در فارسی به یاتاقان یا بالشتک ترجمه شده است. کلمه بلبرینگ هم که به صورت رایج و البته به نادرست به کلیه برینگ ها اطلاق می شود، تنها به آن دسته از برینگ ها گفته می شود که جزء غلتشی در آنها ساچمه است. بنابراین به طور دقیق تر باید برینگ هایی را که جزء غلتشی آنها غلتک می باشد، رولبرینگ نامید. برخی از مهمترین انواع برینگ ها عبارتند از:

    خرابی بلبرینگ ها، علل و روش های پیشگیری

    با توجه به نقش مهم بلبرینگ های غلتشی در ماشین آلات گوناگون، اهمیت شناخت علل خرابی آنها و ممانعت از بروز آن واضح می نماید. متأسفانه عدم حصول بلبرینگ به طول عمر محاسبه شده امری غیرعادی نیست. دلایل زیادی برای این امر ممکن است وجود داشته باشد. نظیر:

    –  مقدار بار بیشتر ازحد پیش بینی شده
    –  روانکاری ناقص یا نامناسب
    –  استفاده نادرست
    –  آب بندی غیر مؤثر
    –  انطباق خیلی فشرده و در نتیجه لقی داخلی کمتر از حد لازم

    آشنایی با پسوند برینگ ها

    اکثر برینگ ها علاوه بر شماره اصلی که بیانگر نوع و اندازه ابعاد آن ها است دارای پسوند نیز می باشند که هر پسوند معرف ویژگی خاصی در طراحی داخلی یا بیرونی برینگ است . پسوند ها در نام گذاری برینگ ها نقش مهم و تأیین کننده ای دارند. آشنایی با پسوند ها می تواند کمک بزرگی باشد جهت انتخاب صحیح برینگ مورد نیاز و عدم آشنایی و استفاده نا به جا از برینگ ها می تواند خسارات زیادی در پی داشته باشد. آنچه در ادامه می آید، بررسی است اجمالی، درباره انواع پسوند های رایج مورد استفاده در بلبرینگ ها و رولبرینگ ها. البته باید توجه داشت که این پسوند ها از استاندارد خاصی پیروی نمی کنند و توسط سازندگان تأیین می شوند. به همین دلیل ممکن است در برند های مختلف، کاملاً یکسان نباشند.

    China renews anti-pollution policy

    BEIJING — A revamped pollutant discharge policy requires all stationary sources of pollution in China to have discharge licenses by 2020.

    “Air and water quality in many regions have failed to meet standards for a long period, which is directly linked to emissions from stationary pollution sources,” said Sun Youhai, head of Tianjin University law school.

    The policy comes as China’s environmental management is failing to adapt to new circumstances. Companies have been required to obtain pollutant discharge license since the late 1980s, but the results have proved unsatisfactory due to poor supervision by environmental agencies, according to Zhao Yingmin, deputy minister of environmental protection.

    Housing Bearing

    A pillow block, also known as a Plummer block or housed bearing unit, is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. Housing material for a pillow block is typically made of cast iron or cast steel.
    A pillow block usually refers to a housing with an included anti-friction bearing. A pillow block refers to any mounted bearing wherein the mounted shaft is in a parallel plane to the mounting surface, and perpendicular to the center line of the mounting holes, as contrasted with various types of flange blocks or flange units. A pillow block may contain a bearing with one of several types of rolling elements, including ball, cylindrical roller, spherical roller, tapered roller, or metallic or synthetic bushing. The type of rolling element defines the type of pillow block. These differ from “plumber blocks” which are bearing housings supplied without any bearings and are usually meant for higher load ratings and a separately installed bearing.

    Other Power Transmitters (Linear / Ball Screw / Belt / Chain)

    Linear ball bearings

    The linear ball bearing (also called ball bushing or shaft guiding) consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. Recirculating balls provide unlimited stroke at low friction movement.

    Linear ball bearings are available in two design ranges: the LBBR series (ISO series 1) and the LBC series (ISO series 3).

    Special & High precision & Technical Bearing

    Specialized Bearings

    There are, of course, several kinds of bearings that are manufactured for specific applications, such as magnetic bearings and giant roller bearings. Magnetic bearings are found in high-speed devices because it has no moving parts—this stability enables it to support devices that move unconscionably fast. Giant roller bearings are used to move extremely large and heavy loads, such as buildings and large structural components.

    Super-precision bearings

    Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges.

    Thrust Ball Bearing

    These kinds of bearings are designed to handle almost exclusively thrust loads in low-speed low-weight applications. Bar stools, for example, make use of ball thrust bearings to support the seat.
    Roller thrust bearings, much like ball thrust bearings, handle thrust loads. The difference, however, lies in the amount of weight the bearing can handle: roller thrust bearings can support significantly larger amounts of thrust load, and are therefore found in car transmissions, where they are used to support helical gears. Gear support in general is a common application for roller thrust bearings.

    Roller ball Bearing

    Roller bearings are designed to carry heavy loads—the primary roller is a cylinder, which means the load is distributed over a larger area, enabling the bearing to handle larger amounts of weight. This structure, however, means the bearing can handle primarily radial loads, but is not suited to thrust loads. For applications where space is an issue, a needle bearing can be used. Needle bearings work with small diameter cylinders, so they are easier to fit in smaller applications.
