Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bearing seat, specifically, high bearing capacity bearing seat. BACKGROUND

[0002] Bearing seat is a supporting component of rotary parts, which needs to have a large bearing capacity. Turntable bearing seat is a kind of bearing seat that can accept comprehensive load or is specially constructed for large and extra-large bearing seats. It has the characteristics of compact structure, sensitive rotation and convenient maintenance. 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 known bearing seat. Since different bearing seats can be selected for a bearing, and different types of bearings can be selected for a bearing seat, there are many types of bearing seats. However, the same bearing seat model is not completely the same in different company samples. For different applications of standard bearing seats, different materials can be selected for bearing seats, such as gray cast iron, ductile cast iron, cast steel, stainless steel, or special plastic bearing seats. Because the bearing sleeve is in a state of wear for a long time, it often needs to be replaced. The existing bearing seat is often fixed and disassembled by traditional bolts to replace and maintain the bearing sleeve. It is not convenient to quickly replace the bearing sleeve, which reduces the replacement efficiency.
