轴承座托辊配件。 Bearing seat roller fittings. 托辊密封圈用与带式输送机的托辊两端一种能防水、防尘侵入有效保护托辊轴承的新型托辊密封。它是由内侧封、外侧封、轴承、中封、端封五部分组成，装在小轴上，并用轴用卡簧作为轴向定位和轴向受力，使中封和端封形成型防水腔和偏心球面气旋腔，从而达到轴承防水、防尘的功能。内密封圈与外密封圈进行紧密结合，新城不同形式的迷宫形式。本实用新型结构简单合理，可有效地防止水和粉尘侵入托辊轴承内部，托辊配件现货，因此提高托辊的使用寿命。 A new type of roller seal with waterproof and dustproof to protect the roller bearing of the roller sealing ring and belt conveyor. It is formed by the medial, lateral sealing, bearing, seal, sealing side sealing of five parts, in small axis, and shaft with the circlip as axial positioning and axial force, make the sealing and end seal type eccentric spherical cyclone and waterproof cavity, so as to achieve the function of the bearing is waterproof, dustproof. The inner sealing ring is closely combined with the outer sealing ring, the different form of the maze in the new city. This practical new structure is simple and reasonable, which can effectively prevent the water and dust from entering the inside of the roller bearing, and the roller parts are in stock, so the service life of the roller is improved.
