Description

Technical Field

[0001] The utility model relates to the field of bearing seats, in particular to a combined bearing seat with adjustable shaft spacing. Background Technique

[0002] A bearing seat is a large and extra-large bearing seat that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, convenient installation and maintenance, etc. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is the commonly said bearing seat. Bearing seats are widely used in large rotary installations such as hoisting and transportation machinery, mining machinery, construction machinery, port machinery, ship machinery, and high-precision radars. Bearings are one of the most widely used components in the field of mechanical manufacturing. Correspondingly, the bearing seats used in different machines are also different. Due to the different machines applied, the appearance, strength, and applicable performance of the bearing seats are also different. Since some machines that can apply bearing seats need to change the shaft spacing at any time to work.

[0003] According to a combined bearing seat with an adjustable shaft spacing function disclosed in Chinese Patent No. CN206723267U, which includes an outer base ring, a tubular bearing base, a slide rail, and an inner bearing ring. The inner bearing ring is movably installed inside the outer base ring. The bottom of the outer base ring is fixedly connected to the tubular bearing base. The slide rail is movably connected inside the tubular bearing base. A load-bearing pulley is fixedly installed on the upper part of the inner wall of the tubular bearing base. Guide pulleys are fixedly installed on both sides of the inner wall of the tubular bearing base. In the above patent solution, the slide rail is used to cooperate with the bearing seat for sliding adjustment. When adjusting, it is necessary to manually control the spacing adjustment between the bearing seats, resulting in inconvenient adjustment of the bearing seats. Therefore, we propose a combined bearing seat with adjustable shaft spacing to solve the above problems. Content of the Utility Model
