Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a bearing which is convenient for internal cleaning. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. The working principle of bearings is to use the rolling of rolling elements between inner and outer rings to reduce the friction between mechanical parts, and the contact line pressure between the rolling elements and the inner and outer rings is the key to the load that the bearing can withstand. There are various types of bearings, including sliding bearings and rolling bearings. Among them, rolling bearings are more diverse, such as angular contact ball bearings, spherical roller bearings, thrust spherical roller bearings and tapered roller bearings. Each bearing has its own unique characteristics and application scenarios. For example, the contact angle of an angular contact ball bearing affects its axial load level and adaptability to high-speed operation; a spherical roller bearing can automatically adjust the misalignment of the axis caused by the deflection or differential center of the shaft or housing. The application range of bearings is very wide, covering almost all fields of mechanical equipment that require rotational motion, such as metallurgy, wind power, mining machinery, aerospace, automotive parts, etc. In daily life, bearings are also commonly used in various equipment, such as car rear wheels, transmissions, household appliances, motors, instruments, etc. In addition, bearings are also used in some occasions that require precise rotation and reduced friction, such as toys, clocks, electronics, and precision shaft zeros of audio-visual equipment.

[0003] The utility model discloses a bearing which is easy to install and has the announcement number of CN208816540U, and relates to the technical field of bearings. The utility model comprises an inner ring and an outer ring, wherein an annular opening is provided on the outer peripheral side of the inner ring; ten rotating rods are arranged in an annular array on a relative surface in the annular opening; the peripheral side surfaces of the ten rotating rods are all rotatably connected with a connecting rod; a slider is fixed on an end surface of the connecting rod; a spring is fixedly connected between the ten rotating rods; the inner ring is slidably connected with a connecting ring through a surface of the slider; a first slide groove is provided on the inner peripheral side surface of the connecting ring; a second slide groove is provided on the outer peripheral side surface of the connecting ring; the connecting ring is rollingly connected with a ball assembly through the second slide groove; the ball assembly comprises a plurality of upper arc-shaped connecting members and a plurality of lower arc-shaped connecting members. The utility model is conducive to reducing the pressure generated by the inner ring on the outer ring when the bearing is installed through the functions of the rotating rod, the nut, the connecting rod, the slider, the spring, the first slide groove and the connecting ring, so as to prevent the bearing from being easily damaged during the press-fitting process. In this scheme, the structure is relatively complicated, and the bearing needs to be disassembled when cleaning the inside, and the cleaning efficiency is relatively slow. Therefore, a bearing which is easy to clean the inside is proposed. Utility Model Content
